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 :
@ discha rged vehicle bat te ry, @ booste r battery
The procedure described below for connecting
jumper cables is intended to provide a jump start
for your veh icle.
Vehicle with discharged battery:

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
