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

Fuses and bulbs
bulb holders that can cause serious cuts. If
you are uncertain about what to do, have
the work performed by an authorized Audi dealer or qualified workshop . Serious per­
sonal injury may result from improperly per·
formed work .
@ Tips
-If you still prefer to replace the light bulbs
yourself, be aware that the engine compart­ ment is a hazardous area to work in~.&.

Working in the engine compartment on
page 155 .
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb.

Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
CD Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle.
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked:
plus(+) cable in most cases colored red
minus(·) cable
in most cases colored black.
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. 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 dead battery can freeze at temperatures
around 32 °F (0 °C). If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­
ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid 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 explosive gases.
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12-Volt rating. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah" rating may cause an explo­
sion 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 weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity (Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
qpage 155.
CD 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 al­
ready start to flow as soon as the positive
(+) terminals are connected.
203

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!

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!
