This can cause damage to the electrical sys­
tem and a fire.
(D Note
If a new fuse burns out again shortly after you
have installed it, have the electrical system
checked as soon as possible by an authorized
Audi dealer or authorized Audi Service Fac ili­
ty .
(!) Tips
-The following table does not list fuse loca­
tions that are not used .
- Some of the equipment listed in the follow­

sions or certain optional equipment.

Fuses and bulb s
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 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 .
This applies espec ially to the light bulbs in the
front of your car wh ich you can only reach
through the engine compartment .
Sheet metal and bulb ho lders can have sharp
edges that can cause ser ious cuts, and parts
must be co rrectly taken apart and then p roperly
put back together to help prevent breakage of
parts and long term damage from water that can
enter housings that have not been properly re ­
sea led.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bu lbs for
you, since your dealer has the proper tools, the correct bulbs and the expertise.
Ga s di sc ha rge la mp s (Xe non ligh ts):
Due to the high electrical voltage, have the bulbs
replaced by a qua lified techn ic ian . Head lights
with Xenon light can be identified by the high
voltage sticker.
LED headlights* requ ire no maintenance. P lease
contact your authorized Aud i dealer if a bulb
needs to be replaced.
A WARNING
Contact w it h high -vo ltage components of the
electrical system and improper rep lacement
of gas disc harge (Xenon) head light bu lbs can
cause serious personal injury and death.
- Xenon bulbs are pressurized and can ex ­
plode when being changed.
- Changing Xenon lamps requires the special
training, instructions and equipment.
- Only an a uthorized Audi dea ler or other
qualified workshop s hou ld change the bulbs
in gas disc harge lamps .
326
A WARNING
There are parts with sharp edges on the open­
ings 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 qual ified workshop . Ser ious
pe rsonal inju ry may resu lt from improperly
pe rformed wor k.
(D Tips
- If you must replace the light bulbs yourself,
always remember that the eng ine compart­
ment of any vehicle is a hazardo us a rea to
work in. Always read and heed all WARN­ INGS
~ page 272.
-It is best to ask you r author ized Audi dea le r
w henever you need to change a bulb.

" N .... 0 0 :c ' 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
~ Note
Vehicles with an automatic transmission can­
not 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
c>page 272.
@ 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.
327

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 g round cable to the negative ground
post of the battery manager control unit.
Using the jump start
cable
Both jump start cables must be connected in the
correct order!

The procedure for connecting jump start cables
that is descr ibed next is designed to help jump
start your vehicle.
Vehicle with discharged battery:
~ Turn off lights and accessories, move automatic
transmission lever to N (Neutral) or P (Park)
and set parking bra ke.
328
Connecting the positive cable (red) to the
positive terminal
~ Open the cover on the positive terminal
qfig . 289.
1. Secure one end of the pos itive cable (red) to
the jump start pin
(D q fig. 290 (pin under
the cover =
"plus") on the vehicle that needs
to be started @.
2. Secure the other end of the positive cable
(red) to the posit ive terminal @on the bat­
tery provid ing the cur rent @.
Connecting the negative cable (black) to the
negative terminal
3. Secure one end of the negative cable (black)
to the negative terminal @ on the battery
that is providing the current @.
4. Secure the other end of the negative cable
(black) to the jump start
pin @ (hex head pin
= "negative") on the vehicle that needs to be
started @.
Starting the engine
~ Sta rt the eng ine on the vehicle providing the
jump start @and let it run at idle.
~ Now start the engine on the vehicle with the
drained battery @.
~ If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approx imately 30 seconds.
~ Remove the cables when the engi nes are run­
ning. Remove them in reverse order from the
way they were installed.
~ Close the cover on the posi tive terminal.
The battery is vented to the outside to prevent
gases from enter ing the vehicle interior. Make
sure that the jumper clamps are well connected
with their
metal ports in full contact with the
battery terminals .
A WARNING
-To avoid serious personal injury and damage
to the vehicle, 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.

- The veh icle capacity weight figures apply
when the load is d istr ibuted evenly in the
vehicle (passengers and luggage) . When
transport ing a heavy load in the luggage
