- Support the vehicle securely with appro­
priate stands if work is to be performed
underneath the vehicle; otherwise, there
is a potential risk for injury.
- Never use the jack supplied with your
Audi on another vehicle, particularly on a
heavier one. The jack is only suitable for
use on the vehicle it came with.

&_ WARNING
You or you r passengers could be injured
while changing a wheel if you do not fol­
l ow these safety precautions:
-If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo­
torists .
- Make sure that passengers wait in a safe
p lace away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possib ly slipping off the
jack, always fully set the parking brake
and block the wheel d iagonally opposite
the wheel be ing changed. When one
front wheel is lifted off the ground, plac­ ing the Automatic Transmission in "P"

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs s ince in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb . Thi s applies especially to the light bu lbs
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 ser ious cuts, and parts
must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been
properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
Headlights with Xenon light can be ident ified
by the high voltage sticke r.
LE D headlights* require no ma intenance .
Please contact your authorized Aud i dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
p lode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bu lbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work ­
shop. Serious personal injury may result
from improperly performed work.
(D Tips
-If you must replace the light bulbs your­
self, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. Always read and
heed all WARNINGS
c> page 231.
-It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.

@ Tips
-The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative
post because the battery manager sys­
tem must be able to detect the battery's
state of charge . Always connect the neg­
ative ground cable to the negative
ground post of the battery manager con­
trol unit.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described below!

•Turnoff lights and accessories, move lever
of automatic transmission to N (Neutral) or
P (Park) and set parking brake.
Connect POSITIVE(+) to POSITIVE(+)
(red)
• Open the red cover on the pos itive terminal
¢ fig. 233 .
1. Connect one end of the red positive cable
on the
jump start bolt c::;, fig. 234 @ (bolt
under the red cover = "positive ") of the ve ­
hicle to be started @.
2. Connect the other end to the positive ter-
mina l@ of the booster battery@.
Connect NEGATIVE (-) to NEGATIVE (-)
(black)
3. Connect one end of the black negative ca­
ble to the negat ive terminal @ of the
booster battery @.
4. Connect the other end to the
jump start
pin © (bolts with hex head bolt= "nega­
tive") of the vehicle to be started @.
Starting the engine
• Start the engine of the veh icle w ith the
booster battery@. Run the engine at a
moderate speed.
• Start engine with discharged vehicle battery
@ in the usual manner.
• If the engine fails to start, do not keep the
starter cranking for longer than 10 seconds.
Wait for about 30 second s and then try
aga in.
• With engine running, remove jumper cables
from both vehicles in the exact
reverse o r­
de r.
• Close the red cover on the positive term inal.
T he battery is vented to the outside to prevent
gases from entering the veh icle inter ior. Make
sure that the jumper clamps are well connect­
ed with their metal parts in full contact with
the battery terminals.
_& WARNING
To avoid serious personal injury and dam­
age to the vehicle, heed all warnings and
instructions of the jumper cable manufac­
turer. If in doubt, call for road service.
- Jumper cables must be long enough so
that the veh icles do not touch.
