208 Check ing and filling
- To reduce the r isk 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 flu ids on hot engine compo­
nents . They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electr ic fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the eng ine is still warm . The cool­
ant system is pressur ized and hot coo l­
ant could spray out.
- Protect your face, hands and arm from
steam o r hot eng ine coolant by placing a
thi ck rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any c ircumstances. Th is increases the
risk of burns.
- If wo rk on the fuel system or the electri­
c al system is necessa ry:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames . Fluids in the engine com­
pa rtment cou ld start a fire.
- Keep an approved fire extinguisher im­
mediately avai lable.
- To avoid electrical s hock and persona l in ­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Othe r components of the high voltage
e lectronic ignition system.
- If you must perform a check or repa ir
with the engine running:
- First, fully apply the parking bra ke,
move se lector lever o f automat ic trans­
missio n to "P" (Park). -
Always use extreme caution to p revent
clothing, jewel ry, 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 wea r clothing that
will hang o r droop into t he engine.
- Mi nimize exposure to em ission and
chemical hazards~ &.
A WARNING
Ca lifo rnia Proposition 65 Wa rning:
- Eng ine exhaust, some of its const ituents,
and certain vehicle components contain
or emit chemicals know n to the State of
California to cause cancer and birt h de­
fects and reproduc tive harm. In addition,
certain fl uids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the
State of California to cause cancer and b irth defects or other reproductive harm.
- Battery posts, terminals and related ac­ cessories conta in lead and lead com ·
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands afte r handling .
(I) Note
When adding f lu ids, always make sure that
they are poured i nto the proper conta iner
or filler opening, otherwise serious dam­
age to vehicle systems w ill 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 veh icle flu­
i ds, have yo ur vehicle inspected by a n au­
thor ized Audi dea ler.

216 Check ing and filling
-If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
-Do not add any type of radiator leak seal­
ant to your vehicle's engine coo lant.
Adding rad iator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty .
- Coolant pollutes the environment and
could cause an engine fire . Excess cool­
ant wil l be forced out through the pres­
s u re re lief valve in the cap when the en­
gine becomes hot.
- If, in an emergency , only water can be
added, the correct ratio between wate r
and antifreeze
c::> page 214 must be re ­
stored as soon as possib le .
@ For the sake of the environment
Dra ined coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself.
The radiator fan is dr iven by the engine via the
V-be lt . T he viscous clutch regulates the speed
of the fan accord ing to the temperature o f the
coolant .
A n auxiliary e lectr ic radiator fan* switches on
and off depending on coolant temperature
and other vehi cle operating conditions.
After you switch the engine off, the auxiliary
fan can cont inue runn ing for up to 10 minutes
- even with the ignition off.
It can even sw itch
on again later by itself
c::> .&. , if
- the temperature of the engine coolant rises
due to the heat bu ild-up from the eng ine in
the engine compartment, or -
the engine compa rtment heats up because
the vehicle is parked in intense sunlight.
.&_ WARNING .........
- To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature
contro lled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper ­
ature drops .
