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.

A WARNING
- 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.
- Tu rn the cap slowly and very ca refully
in a counte r-clockw ise d irection while
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
and an tifreeze<=> page 201 must be re
stored as soon as possib le .

@) 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.
