A WARNING
Do not repair fuses and never replace a blown
fuse with one that has a higher amp rat ing .
This can cause damage to the electr ical sys­
tem and increases the risk of fire.
(D Note
If a new fuse burns out again shortly after you
have installed it, have the electrical system
checked as soon as poss ible by an authorized
Audi dealer or authorized Audi Service Facili­
ty.

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

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!

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:
.. 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. ..,.

Gross Axle Weight Rating
The G ross Ax le We ight Rating is the max imum
load that can be applied at each axle of the vehi ­
cle ¢& .
Vehicle capacity weight
The vehicle capacity we ight (max. load) is l isted
on the d river's side 8-p illar.
_& WARNING
- T he ac tual Gross Axle Weight Rating a t the
front and rear axles sho uld not exceed the
permissible weights, and their combination
must not exceed the Gross Veh icle Weight
Rating.
Dimensions
- Exceed ing permissible weight ratings can
result in vehicle damage, accidents and per­
sonal injury.
(D Note
- The vehicle capacity weight figures apply
when the load is d istr ibuted evenly in the
vehicle (passengers and luggage). When
t ransporting a heavy load in the luggage
compartment, carry the load as near to the
rea r axle as possib le so that the vehicle's
hand ling is not impaired .
- Do not exceed the max imum perm iss ible
axle loads or the maximum gross vehicle
we ight. Always remember that the ve hicle's
han dling will be affe cted by the extra load.
T herefore, a djust your speed acco rd ingly.
