Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Aud i dea ler rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas di schar ge la mps (Xe no n ligh ts):
Due to the high electr ical voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the hig h volt­
age st icker.
LED headlights* require no maintenance . Please
contact your authorized Audi dea ler if a bulb
needs to be replaced.
_&. WARNING
Changing Xenon lamps wi thout the necessary
equipment can cause serious personal injury .
- Bulbs are pressu rized and can explode when
be ing changed. Potent ial ris k of injury!
- On veh icles equipped with gas disc harge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
high-vo ltage portions of such lamps!
- Only your authorized A udi dealer or quali­
f ied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
201

Emergency situations
@ Tips
The discharged battery must be properly con­
nected 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
negat ive ground cable to the negative ground
pos t of the battery manager control unit.
Use of jumper cables
Make sure to connect the jumper cable clamps in
exactly the order described below!
Fig. 160 Engine compartmen t: Connectors fo r ju m pe r ca ­
bles and charger
Fig. 161 J u mp starting w ith the battery of another vehicle :

The procedure described below for connecting
jumper cables is intended to provide a jump start
for your veh icle.
Vehicle with discharged battery:
.. Turn off lights and accessories, move lever of
automatic transmission to
N (Neutral) or P
(Park) and set park ing brake .
204
Connect POSITIVE(+) to POSITIVE (+) (red)
.. To access the positive terminal, remove the
battery cover
r:!) fig. 160.
1. Connect one end of the red positive cable on
the
jump start bolt (D ~ fig. 161 (Bolt under
cover= "positive") of the vehicle to be start­
ed @.
2. Connect the other end to the positive termi-
nal@ of the booster battery @.
Connect NEGATIVE(-) to NEGATIVE(-)
(black)
3. Connect one end of the black negative cable
to the negative terminal ® of the booster
battery @.
4. Connect the other end to the
jump start
bolt @
(Bolt with hex head = "negative") of
the vehicle to be started @.
Starting the engine
"'Start the eng ine of the vehicle with the booster
battery @. Run the eng ine at a moderate
speed .
.,. Start engine w ith 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 seconds and then try again .
.. With engine running, remove jumper cables
from both vehicles in the exact
reverse order.
"' Fit the cover back onto the battery .
The battery is vented to the outside to prevent gases from entering the vehicle interior . Make
sure that the jumper clamps are well connected
with their
metal parts in full contact with the
batte ry terminals.
A WARNING
To avoid serious personal inju ry and damage
to the veh icle, heed all warnings and instruc­
tions of the jumper cable manufacturer.
If in
doubt, call for road service.
- Jumper cables must be long enough so that
the vehicles do not touch .
- When connecting jumper cables, make sur e
that they cannot get caug ht in any moving
pa rts in the engine compartment. ..,.

-Do not bend over the batteries -danger of
chemical burns!
- The battery cell locking screws must be
tightened securely.
- Before you check anything in the engine
compartment, a lways read and heed all
WARNINGS
¢ page 155.
(D Note
Improper hook-up of jumper cables can ruin
the generator.
- Always connect POSITIVE(+) to POSITIVE
( + ), and NEGATIVE(-) to NEGATIVE(-)
ground post of the battery manager contro l
unit.
- Check that all screw p lugs on the battery
cells are screwed in firmly . If not, tighten
plugs prior to connecting clamp on negative
battery terminal.
- Please note that the procedure for connect­
ing a jumper cable as described above ap­
plies specif ically to the case of your vehicle
being jump started. When you are giv ing a
jump start to another vehicle, do
not con­
nect the negative( -) cab le to the negative
(-) terminal on the discharged battery@
¢ fig. 161. Instead, securely connect the
negative (-) cable to either a solid metal
component that is firm ly bolted to the en­
gine block or to the engine block itself. If
the battery that is being charged does not
vent to the outs ide, escaping battery gas
could ignite and explode!

today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
gine and transmission parts which an owner can perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and other
equipment available to specially trained work ­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and
its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for upholding a possible warranty claim made within
the warranty period.
Above all , operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any other properly equipped and qualified workshop. We strongly urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­ nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of
procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicable text and careful­ ly follow the instructions given . Always rigorously
observe the
WARNINGS provided .
Before you check anything in the engine com­
partment, always read and heed all WARNINGS
c::> .&. and c::> .&. in Working in the engine compart­
ment on page 155. Consumer Information
A WARNING
-
Serious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when working
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­
mon sense. Never risk personal injury.
- Do not attempt any of the maintenance,
checks or repairs described on the following
pages if you are not fully familiar with these
or other procedures with respect to the ve­
hicle, or are uncertain how to proceed.
- Do not do any work without the proper tools
and equipment. Have the necessary work
done by your authorized Audi dealer or an­
other properly equipped and qualified work­
shop.
- The engine compartment of any motor vehi­ cle is a potentially hazardous area. Never
reach into the area around or touch the radi­
ator fan.
It is temperature controlled and
can switch on suddenly - even when the en­
gine is off and the ignition key has been re­
moved. The radiator fan switches on auto­
matically when the coolant reaches a certain
temperature and will continue to run until
the coolant temperature drops.
- Always remove the ignition key before any­
one gets under the vehicle.
- Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle . The jack* supplied with the vehi­
cle is not adequate for this purpose and
could collapse causing serious personal in­
jury.
- If you must work underneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that the engine cannot be started.
- Always make sure the transmission selector
lever (automatic transmission) is in P (Park
position) and the park brake is applied.
