tion key. The lo cked steering helps prevent ve ­
hicle theft .
Emergency off
If it is necessary in unus ual circumstances, the
engine can be switched off while the veh icle is
moving. The engine will be switched off if you
press on the key for an extended period .
A WARNING
-Never turn off the engine before the ve­
hicle has come to a comp lete stop. The
full funct ion of the brake booster and the
power steering is not guaranteed . You
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to crashes and ser ious injuries.
- For safety reasons, you should always
pa rk your vehicle w ith the selector lever
in P . Otherw ise, the vehicle could inad ­
verten tly roll away.
- The radiator fan can continue to run fo r
up to 10 minu tes even after you have
turned off the engine and removed the ignition key. The radiator fan can a lso
turn on again if the engine coo lant heats
up because of intense sunlight or heat
bui ld-up in the engine compartment.
- Always take the key with you whenever
you leave your vehicle. Otherw ise, the
engine could be started or electrical
equ ipment such as the power windows
could be operated . This can lead to seri­
ous injury.
- Never leave children or persons requiring
assistance unattended in the vehicle. The
doors can be locked using the remote
transmitter, preven ting people from es­
caping from the veh icle on their own in
the event of an emergency . Depending
on the time of year, peop le inside the ve ­
hicle can be exposed to very high or very
low temperatures. ..,.

196 Checking and filling
-To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
- Keep children away from the engine com ­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­ partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of automatic trans­
mission to "P" (Park). -
Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts . Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~& .
A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition,
certain fluids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the
State of California to cause cancer and birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories contain lead and lead com·
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms . Wash hands after handling .
(I) Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam ­
age to vehicle systems will occur.
@) For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other vehicle flu­
ids, have your vehicle inspected by an au­
thorized Audi dealer.

- The cooling system is under pressure and
can get very hot. Reduce the risk of
sca lding from hot coolant by following
these steps .
- T urn off the engine and a llow it to cool
down.
- Protect your face, hands and arms from
escap ing flu id and steam by cover ing
the cap with a large, thick rag.

applying light, downward p ress ure on
the top of the cap.
- To avo id being burned, do not sp ill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glyco l in en­
g ine coolant can catch f ire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its or iginal container and we ll
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clear ly marked "poison".
Q) Note
- Do not add any type of radiator leak sea l­
ant to your veh icle's engine coolant.
Adding rad iator repair fluid may adverse­
l y affect the function and performance of
you r cooling system and could result in
damage not covered by your New Vehicle Limited Wa rra nty.
- Coolant pollutes the env ironment and
could cause an engine fire. Excess coo l­
ant w ill be forced ou t through the pres­
su re re lief va lve in the cap when the en­
gine becomes hot .
- If, in an emergency, only water can be
added, t he cor rect ratio between wate r

@) For the sake of the environment
Drained coolant sho uld not be reused. A l­
ways d ispose of used coolant while observ­
i ng a ll environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself .
T he radiator fan is dr iven by the engine via the
V-belt. The viscous clutch regulates the speed
of the fan according to the temperature of the coolant.
An a uxiliary electric radiator fan* switches on
and off depending on coolant temperature
and othe r vehicle ope rat ing cond it ions.
After yo u switch the eng ine off, the aux iliary
f an can continue running for up to 10 m inutes
- even with the ignition off. It can even switch
on again later by itself<=>.&. , if
- t he temperatu re of the engine coo lant rises
due to the heat build -up from the engine in
the engine compa rtment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlight.
A WARNING
=
- To reduce the risk of personal inju ry nev-
er touch the radiator fan.
- The a uxiliary electric fan is tempe rat ure
contro lled and can switch on suddenly
even when the engine is not running.
- The a uxiliary radiator fan switches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops.
