Bulbs
Replacing light bulbs
For your safety, we recommend that you have your autho­
rized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more difficult to replace
vehicle light bulbs since in many cases, other parts of the car must
first be removed before you are able to get to the bulb. This applies
especially to the light bulbs in the front of your car which you can
only reach through the engine compartment.
•
Sheet metal and bulb holders can have sharp edges that can cause
serious cuts, and parts must be correctly taken apart and then prop-.,

If th e engine shou ld fai l to start because of a discharged or weak
ba ttery , the bat te ry can be connected t o the ba ttery of
another
vehic le, using a pair of jumper cables to start the engine.
Jumper cables
Use
only jumper cabl es o f sufficient ly la rgecross section to carry the
st arte r current safe ly . R efer to th e manu fac tur er's speci fica tions.

& WARNING
Batteries contain electricity , acid , and gas . Any of these can cause
very serious or fatal injury. Follow the instructions below for safe
handling of your vehicle 's battery .
• Always shield your eyes and avoid leaning over the battery
whenever possible .
• A discharged battery can freeze at temperatures just below
32 °F (0 °C l. Before connecting a jumper cable , you must thaw the
frozen battery completely , otherwise it could explode.
• Do not allow battery a cid to contact eyes or skin . Flush any
contacted area with water immediately.
• Improper use of a booster battery to start a vehicle may cause
an explosion.
• Vehicle batteries generate e xplosive gases . Keep sparks, flame
and lighted cigarettes away from batteries.
• Do not try to jump start any vehicle with a low ac id level in the
battery.
• The voltage of the booster battery must also have a 12-Volt
rating . The capacity (Ahl of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
different voltage or substantially different "Ah " rating may cause
an e xplosion and personal injury .
• Never charge a frozen battery. Gas trapped in the ice may cause
an explosion .
• Never charge or use a battery that has been frozen . The battery
case may have be weakened.
• Use of batteries of different voltage or substantially different
capacity (Ah ) rating may cause an explosion and injury . The
capacity (Ahl of the booster battery should not be lower than that
of the discharged battery . .,_

& WARNING !continued)
• Before you check anything in the engine compartment, always
read and heed all WARNINGS~ page 301, "Engine compartment".
0 Note
• Applying a higher voltage booster battery will cause expensive
damage to sensitive electronic components, such as control units,
relays, radio, etc .
• There must be no electrical contact between the vehicles as
otherwise current could already start to flow as soon as the positive
(+) terminals are connected.
[ i) Tips
• The discharged battery must be properly connected to the
vehicle's electrical system. When jump starting or charging the
battery , never connect the negative ground cable to the battery
negative post because the battery manager system must be able to
detect the battery's state of charge. Always connect the negative
ground cable to the negative ground post of the battery manager
control unit .•
Use of jumper cables
Make sure to connect the jumper cable clamps in exactly
the order described below!

& WARNING
• To reduce the risk of serious injury and vehicle damage .
- Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated
=> page 371 , fig . 306 and
=> fig. 307.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
weight distribution and balance. This might happen , for
example, when heavy components such as the engine block or
transmission are removed .
• When removing heavy components like these, anchor vehicle
to hoist or add corresponding weights to maintain the center of gravity. Otherwise , the vehicle might tilt or slip off the hoist,
causing serious personal injury .
0 Note
• Be awar e of the following points be fore liftin g the vehicle :
- The vehicle should never be lifted or jacked up from under­
neath the engine oil pan , the transmission housing , the front or
rear axle or the body side members . This could lead to serious
damage .
- To avoid damage to the underbody or chassis frame, a rubber
pad must be inserted between the floor jack and the lift points .
- Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist . _..
