Warnings and Cautions WARNINGS •

Some repairs may be beyond your capability. If you lack the skills, tools and equipment, or a suitable workplace for any procedure described in this manual, we suggest you leave such repairs to an authorized dealer service department or other qualied shop.



Do not re-use any fasteners that are worn or deformed in normal use. Many fasteners are designed, to be used only once and become unreliable and may fail when used a second time. This includes, but is not limited to, nuts, bolts, washers, self-locking nuts or bolts, circlips and cotter pins. Always replace these fasteners with new parts.



Never work under a lifted car unless it is solidly supported on stands designed for the purpose. Do not support a car on cinder blocks, hollow tiles or other props that may crumble under continuous load. Never work under a car that is supported solely by a jack. Never work under the car while the engine is running.



If you are going to work under a car on the ground, make sure that the ground is level. Block the wheels to keep the car from

4

rolling. Disconnect the battery negative (-) terminal (ground strap) to prevent others from starting the car while you are under it.

  n    l    i   o   a    t   r   a   e   n   m   e   r   o    G   f   n    I



Never run the engine unless the work area is well ventilated. Carbon monoxide kills.



Rings, bracelets and other jewelry should be removed so that they cannot cause electrical shorts, get caught in running machinery, or be crushed by heavy parts.



Tie long hair behind your head. Do not wear a necktie, a scarf, loose clothing, or a necklace when you work near machine tools or running engines. If your hair, clothing, or jewelry were to get caught in the machinery, severe injury could result.



Do not attempt to work on your car if you do not feel well. You increase the danger of injury to yourself and others if you are tired upset or have taken medication or any other substance that may keep you from being fully alert.



Illuminate your work area adequately but safely. Use a portable safety light for working inside or under the car. Make sure the bulb is enclosed by a wire cage. The hot lament of an accidentally broken bulb can ignite spilled fuel, vapors or oil.



Catch draining fuel, oil, or brake uid in suitable containers. Do not use food or beverage containers that might mislead someone into drinking from them. Store ammable uids away from re hazards. Wipe up spills at once, but do not store the oily rags, which can ignite and burn spontaneously.



Always observe good workshop practices. Wear goggles when you operate machine tools or work with battery acid. Gloves or other protective clothing should be worn whenever the job requires working with harmful substances.



Greases, lubricants and other automotive chemicals contain toxic substances, many of which are absorbed directly through the skin. Read the manufacturer's instructions and warnings carefully. Use hand and eye protection. Avoid direct skin contact



Disconnect the battery negative (-) terminal (ground strap) whenever you work on the fuel system or the electrical system. Do not smoke or work near heaters or other re hazards. Keep an approved re extinguisher handy.

Friction materials (such as brake pads or shoes or clutch discs) contain asbestos bers or other friction materials. Do not create dust by grinding, sanding, or by cleaning with compressed air.  Avoid breathing dust. Breathing any friction material dust can lead to serious diseases and may result in death.



Batteries give off explosive hydrogen gas during charging. Keep sparks, lighted matches and open ame away from the top of the battery. If hydrogen gas escaping from the cap vents is ignited, it will ignite gas trapped in the cells and cause the battery to explode.



Connect and disconnect battery cables, jumper cables or a battery charger only with the ignition switched off. Do not disconnect the battery while the engine is running.



Do not quick-charge the battery (for boost starting) for longer than one minute. Wait at least one minute before boosting the battery a second time.



Do not allow battery charging voltage to exceed 16.5 volts. If the battery begins producing gas or boiling violently, reduce the charging rate. Boosting a sulfated battery at a high charging rate can cause an explosion.



The air conditioning system is lled with chemical refrigerant, which is hazardous. The A/C system should be serviced only by trained technicians using approved refrigerant recovery/ recycling equipment, trained in related safety precautions, and familiar with regulations governing the discharging and disposal of automotive chemical refrigerants.



Do not expose any part of the A/C system to high temperatures such as open ame. Excessive heat will increase system pressure and may cause the system to burst.



Some aerosol tire inators are highly ammable. Be extremely cautious when repairing a tire that may have been inated using an aerosol tire inator. Keep sparks, open ame or other sources of ignition away from the tire repair area. Inate and deate the tire at least four times before breaking the bead from the rim. Completely remove the tire from the rim before attempting any repair.



Some cars are equipped with a supplemental restraint system (SRS) that automatically deploys airbags and pyrotechnic seat belt tensioners in the event of a frontal or side impact. These

6

The ignition system produces high voltages that can be fatal.  Avoid contact with exposed terminals and use extreme care when working on a car with the engine running or the ignition switched on.



Place jack stands only at locations specied by manufacturer. The vehicle lifting jack supplied with the vehicle is intended for tire changes only. A heavy duty oor jack should be used to lift vehicle before installing jack stands. See 010 General.



Battery acid (electrolyte) can cause severe burns. Flush contact area with water, seek medical attention.



Aerosol cleaners and solvents may contain hazardous or deadly vapors and are highly ammable. Use only in a well ventilated area. Do not use on hot surfaces (engines, brakes, etc.).



Do not remove coolant reservoir or radiator cap with the engine hot. Danger of burns and engine damage.

CAUTIONS •

If you lack the skills, tools and equipment, or a suitable workshop for any procedure described in this manual, we suggest y ou leave such repairs to an authorized dealer or other qualied shop.



Before starting a job, make certain that you have all the necessary tools and parts on hand. Read all the instructions thoroughly, and do not attempt shortcuts. Use tools appropriate to the work and use only replacement parts meeting original specications. Makeshift tools, parts and procedures will not make good repairs.



Use pneumatic and electric tools only to loosen threaded parts and fasteners. Never use these tools to tighten fasteners, especially on light alloy parts. Always use a torque wrench to tighten fasteners to the tightening torque specication listed.



Be mindful of the environment and ecology. Before you drain the crankcase, nd out the proper way to dispose of the oil. Do not pour oil onto the ground, down a drain, or into a stream, pond or lake. Dispose of in accordance with Federal, State and Local laws.

The control module for the anti-lock brake system (ABS) cannot withstand temperatures from a paint-drying booth or a heat lamp in excess of 203°F (95°C) and should not be subjected to temperatures in excess of 185°F (85°C) for more than two hours.



Before doing any electrical welding on cars equipped with ABS, disconnect the battery negative (-) terminal (ground strap) and the ABS control module connector.



Always make sure ignition is off before disconnecting battery.



Label battery cables before disconnecting. On some models, battery cables are not color coded.



Disconnecting the battery may erase fault code(s) stored in control module memory. Check for fault codes prior to disconnecting the battery cables.



If a normal or rapid charger is used to charge battery, the battery must be disconnected and removed from the vehicle in order to avoid damaging paint and upholstery.



Do not quick-charge the battery (for boost starting) for longer than one minute. Wait at least one minute before boosting the battery a second time.



Connect and disconnect a battery charger only with the battery charger switched off.



Sealed or "maintenance free" batteries should be slow-charged only, at an amperage rate that is approximately 10% of the battery's ampere-hour (Ah) rating.



Do not allow battery charging voltage to exceed 16.5 volts. If the battery begins producing gas or boiling violently, reduce the charging rate. Boosting a sulfated battery at a high charging rate can cause an explosion.

1) Engine Oil: Only use oils meeting VW oil quality standard VW502 00. If VW502 00 is not available you may use oil (synthetic preferred) meeting either ACEA A3, A5 or B5; API SL; or ILSAC GF-3 for topping off only (not more than 0.5 qt/ltr). Do not overfill! Overfilling engine oil can cause misfire DTCs to be stored in ECM (J220). To prevent overfillling, add o o approx. 0.5L less than capacity, start engine and let run until engine operating temp. is approx. 60 C (140 F), turn OFF ignition, wait approx. 3 minutes, check dipstick, then fill to MAX. Viscosity 5W40, 5W30 or 0W40. 2) Automatic Trans: New fill quantities are for reference only. Only replace after repair (i.e., when removing oil pan). See RM for details. See ETKA for oil fluid specifics. 3) Differential Automatic Trans: See ETKA for oil fluid specifics. 09G: Capacity included w/auto transmission. 4) Cooling System: Use phosphate-free coolant G 012 A8F A4 [G12+ (purple), Valvoline G12 (purple) is really G12+). Note the following mixing combinations: G11 (green) & G12 (pink) NO; G11 & Valvoline G12 OK; G11 & G12+ OK; G12 & Valvoline G12 OK; G11 & G12 & G12+ NO; G11 & G12 & Valvoline G12 NO. Frost protection is required down to o o o o approx. -25 C (-13 F). In countries with arctic climates, frost protection is required down to approx. -35 C (-31 F). The anti-freeze ratio must be a minimum of 40%, otherwise frost protection is reduced. The recommended mixture ratio is 50:50. If greater frost protection is required (very cold climates), the amount of G 012 A8F A4 can be increased, but only up o o to 60%. This provides frost protection to approx. -40 C (-40 F). Do not reduce the coolant concentration by adding water, even in warmer seasons/countries, as cooling effectiveness will be reduced. 5) Power Steering: Hydraulic oil G 002 000. Do not use ATF. Do not reuse drained fluid. 6) Brake Fluid: Use new brake fluid in accordance with US Standard FMVSS 116 Dot 4. See ETKA for fl uid specifics. Always siphon some brake fluid from reservoir before replacing brake pads. Refer to Warnings and notes in RM – brake section, before working on hydraulic system. 7) A/C Refrigerant Oil: Use PAG oil, Part No. G 052 300 A2, with R-134a.

Note: Part Numbers are for reference only. Always check with your Parts Dept. for the latest parts information.
