Thank you for choosing MercedesBenz. We recommend that you familiarise yourself with the vehicle, its operation and the driving, control and comfort systems before starting your first journey. Please ensure that you read the Operating Instructions before starting your first journey. This will help to avoid endangering yourself and others. Since the scope of delivery depends on the order, certain descriptions and illustrations may differ from the equipment actually installed on the vehicle. The Operating Instructions also describe items of optional equipment, if their operation needs explanation. Country-specific vehicle equipment, limited availability of optional equipment or varying product designations are possible in certain countries.

DaimlerChrysler reserves the right to introduce changes in design, equipment and technical features at any time. You cannot, therefore, base any claims on the data, illustrations or descriptions in these Operating Instructions. Please consult your Mercedes-Benz Service Centre should you have any questions. The Operating Instructions, Summary of control elements, Maintenance Booklet and equipment-dependent supplements are an integral part of your vehicle. You should therefore always keep them in the vehicle and pass them on to the new owner if you sell the vehicle. The technical documentation team at DaimlerChrysler AG wishes you pleasant and safe motoring.

As fuel consumption and engine, brake and tyre wear depend heavily on the style of driving and operating conditions, please bear the following in mind:

A regularly serviced vehicle contributes to environmental protection. The driver information system indicates the service due dates in the multi-function display.

 Make sure that the tyre pressures are always correct.

Always have maintenance work carried out at a qualified specialist workshop.

 Avoid frequent, sudden acceleration.

DaimlerChrysler recommends that you visit a Mercedes-Benz Service Centre as it has the necessary specialist knowledge and tools for the work required. For work relevant to safety and work on safety-related systems in particular, it is essential that maintenance work is carried out at a qualified specialist workshop.

 Do not warm the engine up when the vehicle is stationary.  Change gear in good time and use each gear only up to 2/3 of its maximum engine speed.

6

The objectives are for the natural resources which form the basis for our existence on this planet to be used sparingly and in a manner which takes the requirements of both nature and humanity into account.

7

Operate your vehicle in an environmentally compatible manner, and you will help to protect the environment.

 Switch off the engine in stationary traffic.

10

 Keep an eye on the vehicle's fuel consumption.

Work incorrectly carried out on electronic equipment and its software could stop this equipment working. Since the electronic systems are networked, this might also affect systems that have not been modified. Faults in the electronic systems could seriously impair the operational safety of your vehicle. Always have maintenance work carried out at a qualified specialist workshop.

DaimlerChrysler recommends that you visit a Mercedes-Benz Service Centre as it has the necessary specialist knowledge and tools for the work required. For work relevant to safety and work on safety-related systems in particular, it is essential that maintenance work is carried out at a qualified specialist workshop. The operating safety can be affected by other, unauthorised work or modifications to the vehicle.

Wearing seat belts Ensure that all occupants are wearing their seat belts correctly for every journey. Risk of accident

G

An incorrectly worn seat belt will not provide the necessary degree of protection and could even cause injury. For this reason, make sure that all occupants, especially pregnant women, wear their seat belts correctly for every trip. Always fasten your seat belt before starting the vehicle. Airbags and belt tensioners will only be able to perform their protective function if the occupants are wearing their seat belts properly.

7 8 9

46

Persons less than 1.50 m tall cannot wear the seat belt properly. They therefore require additional restraint systems for protection in an accident. Under no circumstances should the seat belts be modified. They will not be able to function as intended.

i The legal requirements for the use of seat belts and restraint systems should be observed at all times.

1 Belt tongue 2 Buckle 3 Release button

Getting started Adjusting Wearing seat belts correctly  Pull the belt smoothly from the seat belt reel and route it over the shoulder.  Do not twist the belt when fastening.

 Click belt tongue 1 into buckle 2 (it must audibly engage).  Adjust the backrest to an almost vertical position.

 Pass the belt over the middle of the shoulder.

 Check the seat belt during the journey to ensure that it is still correctly routed.

 The belt must not pass around the neck or under the arm.

Releasing the seat belt

 If necessary, pull the belt upwards in front of the chest so that it rests tightly against the chest.  The belt must cross over the hips as low down as possible, i.e. over the hip joint and not across the abdomen.

 Press release button 3 in buckle.  Guide belt tongue 1 back to its out-ofuse position.

Risk of injury

G

1

Only one person should use each seat belt at any one time.

2

Do not use seat belts to secure both objects and persons.

3

The seat belt should always pass closely over the body. Avoid wearing bulky clothing.

4

Under no circumstances should the seat belts be modified. They might no longer function correctly.

5

7 8 9

48

DaimlerChrysler recommends that you visit a Mercedes-Benz Service Centre as it has the necessary specialist knowledge and tools for the work required. For work relevant to safety and work on safety-related systems in particular, it is essential that maintenance work is carried out at a qualified specialist workshop.

Further information can be found in the "Controls in detail" section ( page 68).

Getting started Driving  Driving Starting the engine The starter inhibitor prevents the engine from being started if a gear is selected and the clutch pedal not fully depressed.

 Shift the transmission to neutral. Vehicles with Telligent® gearshift or Telligent® automatic gearshift: The transmission neutral position N must be shown in the multi-function display.  Disengage power take-off. The J power take-off display or the c tipper body indicator lamp must not light up.  Vehicles with flame-start system: Wait until the q indicator lamp goes out ( page 129).

Transmission neutral position N

 Turn the key to position 2 in the ignition lock and wait at least one second until the immobiliser is deactivated.

 Without depressing the accelerator pedal, turn the key to position 3 and hold it in this position until the engine starts.

!

1

Do not drive off straight away. Leave the engine to idle for a short time until sufficient oil pressure has built up. This prevents wear and potential damage to the engine.

Getting started Driving Checking steering wheel play With the engine running  turn the front wheels to the straightahead position.  Turn the steering wheel to left and right. The front wheels must begin to move when the steering wheel is turned by not more than 30 mm (1.2 in), measured at the steering wheel rim.  If this is not the case, have the steering and steering linkage checked immediately.

Risk of accident

G

If the steering wheel play is greater than 30 mm, the vehicle can no longer safely maintain a straight line. The direction of travel will need to be corrected continually. The operating reliability and road safety of the vehicle are jeopardised. Have the steering system inspected. The maintenance work should always be carried out at a qualified specialist workshop. DaimlerChrysler recommends that you visit a Mercedes-Benz Service Centre as it has the necessary specialist knowledge and tools for the work required. For work relevant to safety and work on safety-related systems in particular, it is essential that maintenance work is carried out at a qualified specialist workshop.

Driver's airbag The airbag offers additional protection against injury and complements the protective functions of the belt tensioner and seat belt. The airbag is located beneath the padded boss of the steering wheel. Risk of injury

G

Airbags and belt tensioners will only be able to perform their protective function effectively if the occupants are wearing their seat belts properly and are sitting properly. Because the airbag inflates in a matter of milliseconds, there is a risk of serious injury or death.

Safety Occupant safety

Risk of injury

G

To reduce the risk of serious or fatal injury caused by inflation of the airbag in milliseconds, observe the following:  Choose a seat position that allows you to sit as far back from the airbag as possible, but still allows you to drive the vehicle safely.  Only hold the steering wheel by the rim. Do not lean over the padded boss of the steering wheel while the vehicle is in motion or when the key is in position 2 in the ignition lock. This allows the airbag to inflate fully.  Do not cover the padded boss of the steering wheel or affix badges or stickers to it. Otherwise correct functioning of the airbag cannot be guaranteed.

 Because the airbag inflates in a matter of milliseconds, there is a high risk of injury.  Severe injuries could be caused by being very near the point where the airbag is triggered.  Do not touch any parts of the airbag once it has been triggered. Parts of the airbag could be hot. Correct operation of the airbag module is no longer guaranteed after 15 years of service. For safety reasons, the airbag module should be replaced after 15 years at the latest.

The risk of an accident is higher:  at high speeds, especially when cornering  on wet or slippery road surfaces  if a safe distance is not kept from the vehicle in front The driving safety systems are unable to overcome the laws of physics. For this reason, adapt your driving style to current road and weather conditions.

Anti-lock braking system (ABS) ABS prevents the wheels from locking when the brakes are applied. The vehicle thus remains steerable. It is operational from walking pace, regardless of road surface conditions.

Safety Driving safety systems Telligent® brake system (BS) ®

The Telligent brake system features all the control functions of ABS, ASR and SR. The Telligent® brake system ensures particularly good braking efficiency with an even shorter braking distance. The Telligent® brake system can detect emergency braking situations via the integrated brake assist system. To conserve the wheel brakes, the Telligent® brake system can also employ the vehicle's engine brake/retarder, depending on the laden weight of the vehicle and the weather conditions.

i ®

The Telligent brake system imparts control over the trailer that results in the vehicle and trailer/semitrailer automatically contributing to the braking effort of the entire vehicle and trailer combination in accordance with their weight. This means the vehicle and trailer combination has improved braking characteristics. On 4 x 2 vehicle and semitrailer combinations, the Telligent® brake system monitors the temperature of the wheel brakes.

Lane assist is merely a tool to assist the driver. When driving, you are responsible for keeping the vehicle on the correct lane and in the correct direction. Lane assist can only give a warning when the road lane markings are driven over or crossed if these are easily detectable. Active Lane assist will not give a warning if:  the speed of the vehicle is below 40 mph (60 km/h)

Cruise control (combined acceleration/braking control) Vehicles without Telligent® distance control (ART): Cruise control can store any road speed above 10 mph (15 km/h). Cruise control brakes the vehicle when the set speed is exceeded by 2.5 mph (4 km/h). Cruise control accelerates the vehicle on uphill climbs. On downhill stretches, the continuous brake brakes the vehicle (engine brake/ retarder).

Telligent® distance control (ART) The Telligent® distance control (ART) is a convenience system that supplements the controlling function of the cruise control system (accelerating/braking control) with a distance control function. If the Telligent® distance control detects a slower vehicle ahead, it will slow your vehicle down automatically. Your vehicle will then be driven at the same speed as that of the vehicle ahead at a preset distance. The speed stored in the cruise control memory remains unaffected. As soon as the traffic situation permits, e.g. if the vehicle ahead changes lanes, your vehicle will accelerate up to the stored speed in the cruise control memory.

Telligent® distance control works like a conventional cruise control system when there is no vehicle driving in front. Risk of accident

G

Do not use ART on icy roads or in the fog, for example. The Telligent® distance control cannot automatically adapt the distance to the vehicle in front to changing road and visibility conditions. Telligent® distance control is merely a tool to assist the driver. The driver is responsible at all times for the speed of the vehicle and for maintaining an adequate distance to the vehicle in front.

Telligent® trailing axle The Telligent® trailing axle is a speed-dependent, hydraulically steered trailing axle. It reduces the turning circle of the vehicle and has a positive effect on tyre wear in corners. When the road speed exceeds 30 mph (45 km/h) or when the trailing axle is raised ( page 298), the electronics system locks the wheels in the straightahead position and disengage the trailing axle steering function. When you lower the trailing axle, the Telligent® trailing axle will begin steering the next time the front axle is turned from the straight-ahead position.

Risk of accident

G

When you drive up to kerb stones or drive through tight passages, there is a danger of the tyres or obstacles on the edge of the road becoming damaged. In this case, lock the Telligent® trailing axle steering function.

When you turn the steering lock to position 2, the j indicator lamp in the instrument panel lights up. When the indicator lamp goes out, the Telligent® trailing axle is ready for operation. If the indicator lamp does not go out or comes on when the vehicle is in motion and the ZL system abbreviation is shown in the multi-function display, have the trailing axle checked.

Controls in detail Driving systems The maintenance work should always be carried out at a qualified specialist workshop. DaimlerChrysler recommends that you visit a Mercedes-Benz Service Centre as it has the necessary specialist knowledge and tools for the work required. For work relevant to safety and work on safetyrelated systems in particular, it is essential that maintenance work is carried out at a qualified specialist workshop.

Distribute the load on the vehicle uniformly. Avoid excessive loads on one side. The vehicle's driving, braking and steering characteristics vary with the type of load, the weight and the centre of gravity of the load. Secure loads if necessary.

2 3 4

Excessive loading at the rear will have a particularly adverse effect on the vehicle's handling characteristics. For this reason, greater care and attention are called for when driving with a load at the rear.

5 6

Do not exceed the permissible axle loads, the wheel loads (½ axle load) or the maximum permissible gross vehicle weight. There is otherwise the risk of damage to tyres, the chassis frame and axles.

Vehicles with Telligent® automatic gearshift: The Telligent® automatic gearshift switches off automatically at idling speed (approximately 550 rpm). On uphill or downhill slopes, do not allow the engine speed to drop to idling speed (approximately 550 rpm).

! When driving the vehicle on rough terrain, ensure that the drive wheels always have sufficient grip. Vehicles without ASR: Do not allow the drive wheels to spin. There is otherwise a risk of damage to the differential. Switch on the differential locks. During the journey, check the instrument readings periodically.

Operation Trailer/semitrailer  Trailer/semitrailer Trailer/semitrailer coupling

Coupling up

The trailer tow hitch or semitrailer coupling is one of the vehicle components with particular importance for road safety. Please comply precisely with the manufacturer's operating, care and maintenance instructions. For further information, also see page 416. Risk of accident and injury

G

Risk of trailer breaking away. Check longitudinal play in the trailer tow hitch every day. To do this, move the towbar body of the hitch firmly forwards and back. Do not hold the coupling jaws. No longitudinal play is permitted. If any longitudinal play is detected, have it eliminated at once.

Towing semitrailers Before coupling (if "one-man operation" is possible) make sure that the semitrailer plate is at least 50 mm lower than the upper edge of the coupling plate.  Reverse and couple up the semitrailer.  After coupling up a semitrailer, lock the levers to prevent unauthorised operation which could lead to the coupling becoming detached.  Connect cables and compressed-air lines ( page 375).

Driving could cause the centre of the mudguard to come into contact with the tyres. In order to prevent damage during operation with a semitrailer, DaimlerChrysler recommends that the middle mudguard is removed, provided this is legally permitted.

2 3 4

Risk of accident and injury

G

Objects thrown up by the road surface could injure or endanger other road users. For this reason, make sure that the rear wheels are protected by mudguards when the semitrailer tractor vehicle is driven without a trailer. If various semitrailers are towed, too much play could be present between the kingpin and the coupling plate. This is not permissible. Follow the manufacturer's instructions.

The initial service warning can be programmed to appear from 0 – 30 days before the work is due. Further information is available from any MercedesBenz Service Centre.

If the work is carried out at a MercedesBenz Service Centre, the fact that the work has been carried out professionally will be confirmed in both the driver information system and the Maintenance Booklet.

Any service work carried out should be confirmed in the Maintenance menu. For notes on confirming service due dates, see ( page 174).

Operation Maintenance

Risk of injury

G

Before having maintenance or repair work carried out, it is essential that you read the authoritative sections of the technical documentation relating to maintenance and repair measures e.g.  Operating Instructions and workshop information. Also familiarise yourself in particular with the legal regulations, e.g.  work safety and accident prevention regulations. Otherwise you may not recognise dangers and could injure yourself or others.

Use only operationally-safe support blocks to raise the vehicle for work on the vehicle underside. Do not use the vehicle's jack for this purpose. The vehicle's jack should only be used to raise the vehicle for a short period of time.

i Mercedes-Benz original parts undergo rigorous quality control checks. Each part has been specifically developed and manufactured or selected and adapted to the requirements of Mercedes-Benz vehicles. The function, safety and value of your vehicle are thus maintained. In Germany and some other countries, certain parts are only officially approved for installation and attachment if they comply with legal requirements.

Mercedes-Benz original parts satisfy this requirement. If other parts are used, this could lead to reduced safety standards. The vehicle's warranty and its operating permit could be invalidated. Every Mercedes-Benz Service Centre maintains a stock of MercedesBenz original parts required for maintenance and repair work.

Practical advice Electrical system

Partially masking headlamps – driving on left/right The headlamps are designed so that they illuminate the edge of the carriageway for a particularly long distance. The beam is asymmetrical. If vehicle is driven in countries where traffic drives on opposite side of the road to that of country where vehicle was approved, the beam falls not on the edge of the carriageway, but onto the opposite carriageway. This will dazzle road users travelling in the opposite direction.

Risk of accident

G

In countries where vehicles drive on the opposite side of the road to that of the country where vehicle was approved, there is a risk of dazzling from the asymmetrical dipped beam. To prevent dazzling of oncoming traffic, cover over headlamps with adhesive tape, following the details issued by Mercedes-Benz.

The area of the headlamp lens to be covered may be seen in the relevant illustration below for the vehicle.

 Prepare adhesive tape using commercially approved opaque adhesive tape in accordance with the dimensions,  apply to corresponding area of the headlamp.

Technical data Service products and capacities Coolant The coolant is a mixture of water and a corrosion inhibitor/antifreeze agent or water and a coolant additive without antifreeze properties. In order to maintain corrosion protection and to increase the boiling point, the coolant must remain in the cooling system all the year round.

! The antifreeze/corrosion inhibitor concentration in the coolant should be checked every six months. Renew the coolant every three years, since the level of corrosion protection gradually decreases. Water alone is not permissible as a coolant, even if antifreeze protection is not required. The water in the coolant must satisfy the requirements specified on sheet no. 310 of the MercedesBenz Specifications for Service Products.

If the water quality is not sufficient you must filter and/or treat the water. Information is available from any Mercedes-Benz Service Centre. Do not increase the concentration of corrosion inhibitor/antifreeze beyond 55% by volume (= maximum antifreeze protection). Above this concentration, antifreeze protection deteriorates and heat dissipation is less effective. During the colder months, check corrosion protection and antifreeze more frequently.

Diesel fuels

Adjusting the fuel grade

Only use standard automotive diesel fuels in accordance with DIN EN 590. Grades such as marine diesel fuel, heating oils, etc. are not permitted.

When the vehicle is delivered, the "Adjusting service products" menu of the driver information system is set to the normal sulphur content (in %) in the fuel available in the country of delivery.

! Filter the fuel before adding it when refuelling the vehicle from drums or canisters. This prevents malfunctions in the fuel system as a result of impurities in the fuel. Special additives must not be used as they could lead to malfunctions and engine damage. The use of such additives could affect your warranty rights.

If you refuel the vehicle occasionally or predominantly in other countries, you must adjust the normal sulphur content of this country in the "Adjusting service products" menu in the driver information system. For an overview of sulphur content in % of fuel available in other countries, see ( page 567).

Technical data Service products and capacities Diesel fuels at low temperatures At low outside temperatures paraffin separation may reduce the diesel fuel's freeflowing properties. To prevent operating problems, use diesel fuel with improved flow properties in the winter months. In Germany, winter-grade diesel fuels are sold which remain reliable in operation down to approximately –20 °C. Wintergrade diesel fuel can normally be used without risk of malfunctioning at the outside temperatures expected in the country where it is on sale.

Fuel additives

i Do not use additives in winter diesel fuels. The fuel's flow properties could be impaired by any such fuel additive. If summer-grade diesel fuel or wintergrade fuel with less resistance to low temperatures is in use, add a quantity of flow improver or kerosene, depending on the outside temperatures.

The vehicle is equipped with a fuel preheating system. This improves the flow properties of the diesel fuel by approximately 8 °C. Risk of fire and explosion

G

Adding petrol lowers the flash point of the diesel fuel. This adds to the risk of handling this fuel mixture.

1 2 3 4

Do not add petrol to diesel fuel.

5

Add the additives to the diesel fuel at the appropriate time, before paraffin separation reduces the diesel's flow properties. Malfunctions resulting from paraffin separation can only be removed by heating the entire fuel system, e.g. by stopping the engine in a heated area.

If summer-grade diesel fuel or wintergrade fuel with less resistance to low temperatures is in use, add a quantity of flow improver or kerosene, depending on outside temperatures. Risk of fire and explosion

G

Adding kerosene lowers the flash point of the diesel fuel. This increases the risk of handling this fuel mixture. Mix kerosene with diesel fuel only in the fuel tank.

Bio-diesel fuel (FAME fuel) It is also possible to run the vehicle on biodiesel fuel. This results in  a slightly higher fuel consumption  a slightly reduced engine power output  increased white smoke formation after a cold start Please refer to the notes on Sheet No. 135 of the Mercedes-Benz Specifications for Service Products.

i

Add the kerosene first, then the diesel fuel.

i

Add as little as possible, consistent with outside temperatures.

Comply with the relevant safety regulations.

It is possible to mix standard diesel fuel with FAME fuel (fatty acid methylester).

 Run the engine for a while to ensure that the additive reaches all parts of the fuel system.

564

For safety reasons, only mix bio-diesel fuel with diesel fuel in the vehicle's fuel tank.

Technical data Service products and capacities !  The fuel filter and engine oil filter must be replaced 600 miles (approximately 1,000 km) after switching to bio-diesel fuel.  The fuel filter and engine oil filter must be replaced with every oil change.  Bio-diesel fuel shortens the service life of conventional fuel filters. DaimlerChrysler therefore recommends fitting a special fuel prefilter. Further information is available from your Mercedes-Benz Service Centre.  When switching to bio-diesel fuel the "Service Products" menu of the driver information system is set to FAME ( page 198).

The intervals for oil changes and replacing the engine oil filter are shorter.  Only use bio-diesel fuel in accordance with DIN EN 14214. Special additives are not permitted. Fuels which do not comply with DIN E 14214 or which have had special additives added could cause malfunctions or even engine damage.  Bio-diesel fuel corrodes painted surfaces. For this reason, they must not be allowed to come into contact with paintwork. Rinse off immediately with water. Only use engine oils complying with Sheet No. 228.5 or 228.3 of the Mercedes-Benz Specifications for Service Products.

 If the vehicle is not used for long periods of time, bio-diesel fuel could adhere to components of the fuel system. If the engine is not used for longer periods of time, use up the bio-diesel fuel and run the vehicle for a short time on conventional diesel fuel and leave it in the fuel system. The use of bio-diesel fuels is not recommended for vehicles which spend long periods out of use (e.g. fire engines).  Observe the manufacturer's operating instructions on how to run the auxiliary heating on bio-diesel fuel.

Technical data Tyre pressure table  Tyre pressure table Single tyres Risk of accident

G

If tyre pressures are too low, road safety and tyre life will both be adversely affected; fuel consumption and tyre wear will increase, and there will be an increased risk of tyre damage.

i Tyre pressure changes by approximately 0.2 bar for every 10 °C change in ambient temperature. Remember this when checking tyre pressures inside a building – particularly in winter.

!

!

The tyre pressure on the front axles for Michelin tyres must be set in accordance with the values in the table +1 bar. Do not, however, exceed the maximum permissible tyre pressure of 8.5 bar. Exceptions to this are Michelin tyres which have a recommended tyre pressure of 9 bar.

Use only wheels and tyres of a size approved for this type of vehicle. Comply in particular with the permissible tyre specifications for each country. These specifications may specify a certain type of tyre for your vehicle or prohibit the use of certain types of tyres which may be permissible in other countries.

G

If the driver exceeds the maximum speed of the vehicle, there is a risk of rolling for articulated vehicles. You would also overload the vehicle's brakes and tyres. There is a risk that you could lose control of the vehicle, particularly if you are driving down long steep slopes with a loaded vehicle.

You are responsible for ensuring that the legal maximum permitted speed is not exceeded. Downshift and engage the engine brake early on to make full use of the engine braking effect on long downhill sections. Slow the vehicle down by braking if necessary.
