E quipment that uses a lot of electricity is switch­
ed off temporari ly when you start the engine.
I f the engine does not start im mediately, stop
the s tart ing proced ure and repeat afte r 30 sec­
onds. To restart the engine, t urn the ignition key
back to position @.
A WARNING
-Never allow the engine to run in confined
spaces -danger of asphyxiation .
- Never remove the ignition key from the igni­
tion look while the vehicle is moving. Other­
wise, the steering lock could suddenly en­ gage and you would not be able to steer the
vehicle .
- Always take the key with you whenever you
leave your vehicle. Otherw ise, the engine
could be started or electrical equ ipme nt
such as the power windows cou ld be operat­
ed . T his can lead to serious injury.
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doo rs can be loc ked using the remote trans­
mitter, preventing people from escap ing
from the vehicle on the ir own in the event o f
an emergency. Depend ing on the t ime of
year, peop le inside the vehicle can be ex­
posed to very high or very low tempera­
tures .
(D Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately . This re­
duces unnecessary emissions.
(D Tips
- If it is difficu lt to turn the key to position
(D, turn the steering wheel back and forth
slightly to release the steering wheel lock .
- Some noise after starting the engine is nor­
mal and is no cause for concern.

- The radiator fan can continue to run for up
to 10 minu tes even after you have turned
off the engine and removed the ignition key.
The radiator fan can also turn on again if the
engine coolant heats up because of intense
sunlight or heat build-up in the eng ine com­
partment.
- Always take the key with you whenever you leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to ser ious injury.
- Never leave children or persons requ iring as­
sistance unattended in the vehicle . The
doors can be locked using the remote t rans­

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.

ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke .
- Never work near open flames.
- Always have a working fire extinguisher
nearby
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable - Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­
tor lever in the P (park) position first .
- Always proceed with extreme caution so that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents . Tie back long hair before beginning

~ 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 .
