Checking and Filling
Do not fill coolant above the "MAX" mark. Excess
coolant will be forced out through the pressure relief valve in the cap when the engine becomes
hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps .
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying light, downward pressure 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 certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire .
-Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children .
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison" .
(D Note
- Do not add coolant if the expansion tank is empty. Air could enter the cooling system
and damage the engine. If this is the case,
do not continue driving. Seek professional
assistance .
- Coolant pollutes the environment and could cause an engine fire. Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
- If, in an emergency, only water can be add­
ed, the correct ratio between water and an­
tifreeze
¢ page 224 must be restored as
soon as possible.

® For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulations.
Radiator fan
The radiator fan switches on automatically by it­
self
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even
with the ignition off. It can even switch on again later by itself ¢& . 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 because the
vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal injury never
touch the radiator fan.
- The auxiliary electric fan is temperature con­
trolled and can switch on suddenly even
when the engine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops. -

A WARNING
-=
Whenever working on the battery or on the
electrical system, there is the risk of injury,
accident and even fire. Read and heed the fol­
lowing WARNINGS:
- Always wear eye protection . Do not let bat­
tery acid or any lead particles get on your skin or clothing. Shield your eyes. Explosive
gases can cause blindness or other injury .
- Battery acid contains sulfuric acid . Sulfuric
acid can cause blindness and severe burns.
- Always wear gloves and eye protection. Do
not tilt the battery because acid could leak
out of the ventilation openings.
- If you get battery acid in your eyes or on
your skin, immediately rinse with cold wa­
ter for several minutes and get medical at­
tention .
- If you should ingest any battery acid, seek
medical attention immediately .
- Do not expose the battery to an open flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and nega-
tive cables.
- When working on the battery, be sure not to short-circuit the terminals with tools or oth­
er metal objects. This would cause the bat­
tery to heat up very quickly, which could
lead to damage or explosion and personal
injury .
- When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause personal injury.
- Always keep the battery well out of the
reach of children .
- Before work is done on the electrical sys­
tem, disconnect the negative ground cable.
- Before performing any work on the electri­ cal system, switch off the engine and igni­
tion as well as any electrical equipment . The
negative cable on the battery must be dis­
connected. If you are just going to replace a
light bulb, then it is enough to switch off
the lights .
-
Checking and Filling
-Before disconnecting the battery, switch off
the anti-theft alarm system! Otherwise you
will set off the alarm.
- When disconnecting the battery, first dis­
connect the negative cable and then the
positive cable.
- Before reconnecting the battery, make sure all electrical consumers are switched off. Re­
connect the positive cable first and then the negative cable. Never interchange the ca­
bles - this could start a fire!
- Never charge a frozen or a thawed -out bat­
tery . It could explode! If a battery has fro­
zen, then it must be replaced. A discharged battery can freeze over at 32 °F (0 °C).
- Make sure the vent hose is always attached
to the opening on the side of the battery.
- Never use batteries which are damaged.
There is the danger of an explosion! Always
replace a damaged battery.
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 reproductive problems.
Wash hands after handling.
([) Note
-Do not disconnect the vehicle battery when
the ignition is on or when the engine is run­
ning, otherwise, you will damage electronic
components in the electrical system.
- If your vehicle is going to stand for a long
period of time without being driven, protect
the battery from "freezing", otherwise it
will be damaged and will then have to be re­
placed.
- When opening the doors, the windows low­
er approximately 10 mm automatically. This
function is not available when the battery is
disconnected, which means there is a risk
that the door seal or the window could be
damaged .

can be cracked due to ice formation and can leak
battery acid.
Battery charging (Maximum charging rate of
30 amps /14.8 Volt )
When charging at low voltages (e.g. with a trickle
charge r),
the battery cab les do not have to be
disconnected f irst. The battery caps should
not
be opened when charging a battery.
It is not necessa ry to remove the battery from
the luggage compartment, and it is a lso not nec­
essary to d isconnect the cab les.
Fast ch arging th e battery (cha rgin g ra te
above 14 .8 V olts)
For technical reasons do not use a battery charg­
er that uses vo ltage greater than 14.8 Vo lts to
charge your vehicle's battery.
A WARNING
Charging a battery can be dangerous.
- Always follow the operating instructions
provided by the battery charger manufactur­
er when charging your battery .
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice . Al­
low a frozen battery to thaw out f irst .
- Do not reuse batteries wh ich were frozen.
The battery housing may have cracked and
weakened when the battery froze.
- Charge the battery in a well ventilated area.
Keep away from open flame or electrical
spark. Do not smoke. Hydrogen gas generat­
ed by the batte ry is explosive.
- To reduce the danger of explosion, never
connect or d isconnect charger cab les wh ile
the charger is operating.
- Fast cha rging a battery is dangerous and
should only be attempted by a competent
technician w ith the proper eq uipment .

today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by vehicle owners .
Also , s afety a nd
en viro nm enta l
concerns place very strict limits
on the nature of repa irs and adjustments to en­
g ine and transmission parts which an owner can
perform.
Maintenance, adjustments and repa irs usua lly re­
qu ire spec ial tools, testing devices and other
equ ipment available to specially trained work­
shop perso nnel in order to assure proper per­
formance, reliab ility and safety of the vehicle and
its many systems.
Improper ma intenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of se rv icing in accordance with
the m aintenance schedule may be a condi tion for
upho ld ing a possib le warranty cla im made w ith in
the warranty period .
Above all, operational safety can be adversely af­
fected, creating unnecessary r isks fo r you and
your passengers.
I f in doubt about any servicing, have it done by
your author ized Audi dealer or any other prope rly
equ ipped and qua lified workshop. We st rongly
urge you to give your authorized Audi dealer the
opport unity to perform all sched uled mainte­
nance and necessary repairs . Your dealer has the
fac ilities, origina l parts and trained specia lists to
keep yo ur vehicle runn ing properly.
P e rforming lim it e d ma inten anc e y ours elf
The fo llowing pages describe a limited number of
proced ures which can be performed on yo ur vehi­
cle with ordinary tools, should the need arise and
trained personne l be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicable text and careful­

C o nsum er information
A WARNING
- Ser ious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs.
- Always be extremely careful when work ing
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­ mon sense. Never ris k personal injury.
- Do not attempt any of the maintenance,
checks or repairs descr ibed on the following
pages if you are not fully familia r wi th these
or other procedures w ith respect to the vehi­
cle, or a re unce rtain how to proceed .
- Do not do any work without the proper tools
a nd eq uipment. Have the necessary work
done by your authorized Audi dealer or an­
other properly equipped and qualified work­
shop .
- The engine compar tment o f any motor vehi ­
cle is a potentially hazardous area. Never reach into the area around or touch the radi­
ator fan. It is temperature contro lled and
can switch on suddenly - even when the en­
g ine is off. The radiator fan sw itches on au­
tomatically when the coolant reaches a cer­
tain tempe ratu re and will continue to run
until the coolant temperature drops.
- Always sw itch off the ignition before anyone
gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work underneath
the vehicle. The jack supplied w ith the vehi­
cle is not adequate for this purpose and
