A WARNING
All work on the battery or electrical system in
your vehicle can result in injuries, chemical
burns, accidents or burns. Because of this, all
work must be performed
only by an author­
ized Aud i dealer or authorized Aud i Service
Facility.
A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related acces­
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproduct ive problems.
Wash hands after handling.
(D Note
Protect the vehicle battery against freezing if
the vehicle will be parked for long periods of
time so that it is not destroyed by "freezing"
c:>page207.
@ For the sake of the environment
~ Batteries contain poll uting substances such
as sulfuric acid and lead. Contact an author­
ized Audi dealer or authorized Audi Service
Facility for more information.
Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for several days or
weeks, e lectrical equipment is gradually scaled
back or switched off. This reduces energy use and
ensures the veh icle will be able to start after long
periods of time
c:> page 124. Some convenience
Checking and Filling
functions, such as interior lighting or power seat
adjustment, may not be available under certa in
c ir cumstances. These convenience functions will
be available again once you switch the ignition on
and start the engine .
Even when electrical equipment is switched off,
the equipment can still dra in the vehicle battery
if the vehicle is not driven for long periods of
time . Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery .
T he veh icle battery must be charged every month
to reduce the risk of this happening
c:> page 207 .
Contact an authorized Aud i dea ler or authorized
A udi Service Facility for more information .
Winter operation
Cold weather places higher demands on the vehi ­
cle battery . This results in reduced starting abili­
ty. Have the veh icle battery checked by an au­
thorized Audi dea ler or authorized Audi Service
Facility before the cold time of year.

General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
ope rations.
Starting by pushing or
towing
CD Note
Veh icles 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 shou ld 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 jumpe r cables to start the engine.
Jumper cables
Use only jumper cables of suffic iently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated term inal
clamps which are dis tinct ly marked:
plus (+) cable in most cases colored re d
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 avo id leaning
over the battery whenever poss ible.
- 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 cab les. 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 Aud i dealer or author­
ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery ac id to contact eyes or
skin . Flush any contacted area with water
immed iately.
- Improper use of a booster battery to start a
veh icle may cause an explosion .
- Veh icle batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
away from batter ies.
- 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 rat ing . The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batter ies of different voltage or substantial­
ly different "Ah" rating may cause an exp lo­
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 . T he battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an exp losion 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 198.
CD Note
-App lying a higher voltage booster battery
wi ll ca use expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.

cells are screwed in firmly. If not, t ighten
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 specifically to the case of your vehicle
being jump started. When you are giv ing a
ju mp start to another vehicle, do
not con­
ne ct the negative( -) cab le to the negative
(-) terminal on the discharged ba ttery @
o fig. 209. Instead, securely connec t 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 be ing charged does not
vent to the outs ide, escaping battery gas
could ignite and explode!

Consumer information
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
equ ipped 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 198.

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. The radiator fan switches on au­
tomatically when the coolant reaches a cer­
tain temperature and will continue to run
until the coolant temperature drops.
- Always switch off the ignition before anyone
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. ..,
