A WARNING ,~
- The cooling system is under pressure and
can get very hot. Reduce the risk of scald ing
from hot coolant by following these steps.
- Turn
off the engine and allow it to coo l
down.
- Protect you r face, hands and arms from
escaping fluid and steam by cover ing the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise d irection while applying
light, downward p ressure on the top of
the cap.
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in cond i­
tions, the ethylene glycol in eng ine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its orig inal container and well out
of the reach of children.
- If you dra in the coolant, it must be caught
and safely stored in a proper conta iner
clearly marked "poison".
- Do not add coolant if the expansion tank is
empty. Air cou ld enter the cooling system
and damage the eng ine. If this is the case,
do not continue driving . Seek professional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire. Excess coolant will be
fo rced o ut through the pressure relief valve
i n the cap when the e ng ine be comes hot.
- If, in an emergency, only wate r can be add­
ed, the co rrect r atio betwee n wate r and an­
tifree ze

Rad iator fan
The radiator fan switches on automatically by it­
self .
The radiator fan is driven by the engine via the V­
belt. The viscous clutch regulates th e speed of
the fan accord ing to the temperature of the cool­
ant .
An auxiliary e lectr ic radiator fan* switches on and
off depending on coo lant temperature and other
vehicle operating conditions.
After you switch the engine
off, the auxiliary fan
can continue running for up to 10 m inutes -even
with the ignition
off. It can even switch on aga in
later by itself
Q .& , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up beca use the
veh icle is parked in intense sunlight.
A WARNING
- To reduce the r isk of persona l injury neve r
touch the radia to r fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not ru nning .
- The a uxiliary radiator fan sw itches on auto­
mat ically when the eng ine coolant reaches a
certa in temperature a nd will continue to run
until the coolant temperature d rops.

@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as we ll as the special toots re­
quired and the necessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro­
lyte level checked by an authorized Audi dealer or
qualified workshop. The electrolyte level should
also be checked each time the battery is charged
c> page 189.
Have the battery checked when you take your ve­
hicle in for serv ice. You are well advised to re­
place a battery t hat is older than 5 years.
With certain types of airbag deployment, the battery is disconnected from the vehicle electri­
cal system for safety reasons
c> & in Repair, care
and disposal of the airbags on page 125 .
Disconnecting the battery terminals
Some vehicle functions (power window regula­
tors, for example) are lost if the battery termi­ nals are disconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent th is, the battery should
only be disconnected from the vehicle e lectr ica l
system when abso lutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and maintains starting ca­
pability over a longer pe riod
c> page 157.
Some of the conven ience functions may not oper­
ate, such as the interior lights or the power seat
adjustment. The convenience functions will be
available again when you turn on the ignition and
start the engine.
Checking and Filling
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . This is be­
cause more power is also consumed while start­
ing, and the headlights, rear window defogger,
etc., are used more often.
Avo id unnecessary power consumption, particu­
larly in city traffic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in
c> page 189. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it w ill not freeze. This will prevent it
from be ing damaged and having to be re­
placed.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the engine compart­
ment . Before you check anything in the engine
compartment ,
read and heed all WARNINGS

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 m ust 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 t hat you have
your authorized Aud i dea le r 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 light s):
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
fied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the

today's automobiles, have steadily reduced the
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 equipped 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 177. Consumer information
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 and the ignition key has been re­
moved. The radiator fan switches on auto­
matically when the coolant reaches a certain
temperature and will continue to run until
the coolant temperature drops.
- Always remove the ignition key before any­
one 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.
