pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fue l is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine .
~ WARNING
-The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust ta il pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproof ing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or
heat shields. During dr iv ing, the substance
used for undercoating could overheat and
cause a fire.
(D Note
- Be aware that just o ne tank filling with
lead ed fue l will already ser iously degrade
the pe rformance of the catalytic co nverter .
- Do not exceed the correct eng ine o il level
c::;, page 164.
- Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and th is cou ld cause the
c ata lytic converter to overheat.
- Do not turn off the ignition whi le the vehicle
i s mov ing.
- Do not continue to operate your veh icle un­
der these cond it ions, as otherwise fue l can
r each the cataly tic conve rte r. This cou ld re­
s ul t in ove rheating of the converter, req uir­
i ng its re placement.
- To assure efficient operation of the Em is ­
s ion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
-
Ch eck ing and Filling
-Lack of proper ma intenance as well as im ­
p roper use of the vehicle w ill impair the
f u nct ion o f the emission control system
and could lead to damage.
® For the sake of the environment
Even when the Emiss ion Control System is op­
erating properly, the exhaust gas can have a
su lfur -like exhaust gas sme ll under some op­
erating states. This depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or f illing the tank
wi th lead-free supe r g rade gasoline.
Engine compartment
Working in the engine compartment
Special care is required if you are working in the
engine comportment
For work in th e engine compartm ent su ch as
che cking and filling fluids, there i s a ri sk of in­
jury, scalding , accident s, and burn s. For thi s
reason , follow all the warnings and gene ral
s afety p re caution s prov ided in the following in·
formatio n. The engine compartment is a dan­
gerous area on the vehicle.
c::;, .&. .
A WARNING
-- T urn the engine off.
- Sw itch the ignition off.
- Set the parking brake .
- Move the selector lever into t he P position .
- Neve r open the hood whe n there is steam o r
coo lant escaping from the engine compart ­
ment, because there is a risk that you could
be burned. Wait unt il no steam or coolant is
escaping.
- Let the eng ine cool down.
- Keep children away from the eng ine com -
partment.
- Never sp ill fluids on a ho t engine. These flu ­
ids (such as the anti -freezing agent con ­
tained in the coolant) can ignite .
- Avoid short c ircui ts in the elect rical sys tem.
- W hen working in the engi ne comp artme nt,
remember that the radiator fan can swi tch

~ Add coolant mixed in the correct ratio
¢ page 166 up to the upper marking.
~ Make sure that the fluid level rema ins stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak. Im­
mediately drive your vehicle to an authorized
Audi dealer or authori zed Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and be ing pushed out of the cooling system.
.&, WARNING
The cool ing system is pressu rized and can be­
come very hot. To reduce the r is k of burns
from hot coolant :
- Do not open the coo lant expansion tank cap
when the engine is hot. This increases the risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es -
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth .
- T urn the coo lant tank cap co unterclo ckwise
slowly and keep light pressu re on the cap .
- T o reduce the risk of burns , do not allow any
antifreeze o r coolant to drip onto the ex­
haust system or hot engine components.
T he ethylene glycol in engine coolant can
catch fire under certain circumstances .
- T he coo lant add itive and the coolant can be
dangerous to your health . For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury .
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
cont inue driv ing . See an authorized Audi deal -
Check ing and Filling
er or authorized Aud i Service Facility for assis ­
tance .
- Before the start of winter, have your author­
ized Aud i dea ler or a uthorized Audi Serv ice
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropr iate coo lant add itive is not
availab le in an emergency, do not add any
other additive . You could damage the en­
gine. If this happens, only use water and re­
store the correct m ixtu re ratio with the
specified coolant add it ive as soo n as poss i­
ble .
- Only refill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant .
Radiator fan
T he radiator fan switches on automatically by it ­
self.
An auxiliary e lectr ic radiator fan switches on and
off depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan c a n continue running for up to 10 m inutes - even
with the ignition off . It can even switch on aga in
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 bec ause the
veh icle is parked in in tense sunlight.
.&, WARNING
--
- To reduce the r isk of personal injury never
touch the radiator fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not runn ing .
- The auxiliary radiator fan sw itches on auto ­
mat ica lly when the eng ine coolant reaches a
certa in temperature and will continue to run
until the coolant temperature d rops .

- Make sure no fluids enter the spaces be­
tween the instrument cluster and the
trim, because that could cause damage.
- Controls
- Make sure that no fluids enter the con-
trols, because this could cause damage.
- Safety belts
- Do not remove the safety belts to clean
them.

dealer or authorized Audi Service Facility.
- Textiles/artificial leather/ Alcantara
- Never treat artificial leather/Alcantara
with leather care products, solvents, floor
polish, shoe polish, spot remove or similar
products.
- Have a specialist remove stubborn stains
to prevent damage.
- Never use steam cleaners, brushes, hard
sponges , etc . when cleaning .
- Do not turn on the seat heating* to dry the
seat .
- Objects with sharp edges, such as zippers
or rivets on clothing or belts, can cause
damage to the surface .
- Open hook and loop fasteners, for exam­
ple on clothing, can damage seat covers .
Make sure hook and loop fasteners are
closed .
- Natural leather
- Never treat leather with solvents, floor
polish, shoe polish, spot remover or simi­
lar products.

- To help prevent the leather from fading,
do not leave the vehicle in direct sunlight
for long periods of time. If leaving the ve­
hicle parked for long periods of time, you
should cover the leather to protect it from
direct sunlight.
(D Tips
- Insects are easier to remove from paint that
has been freshly waxed.
- Regular waxing can prevent rust spots from
forming.
