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 .

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention.
T he cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolan t consists of a
mixture of specially conditioned water and the
manufacturer 's glycol-based coolant addi-
tive G13 antifreeze with ant icorros ion addi­
tives (50% for USA models ; 60% for Ca nadian
models) . Th is mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's coo ling system from
corrosion and scaling. It a lso raises the boil­
ing point of the coo lant.
D o not reduce the concentration o f the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive mu st be at
least 50 % but not more than 60 %
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31° F(-35°C)USA
- - 4 0 ° F ( -40 °C) Canada.
I f you must add coo lant, use a m ixture of wa­
ter and coolant addit ive. Mixing the coolant
addi tive wi th disti lled wate r is recommended.
A WARNING
Be fore yo u check any thing in the engine
compartment, always read and heed all
WARNI NGS
~ .&. in Working in the engine
compartment on page 195.
(D Note
- Befo re win ter sets in, have the coolan t
checked to see if t he coolant ad dit ive in
-
Checkin g and fillin g 201
your vehicle is sufficient to meet the cli ­
mate conditions . This is especia lly impor ­
tant if you live in a region where the win ­
ter is extreme ly co ld. If necessary, in­
c rease the p ropo rtion of coo lant add itive
to 60% .
- When adding coolant additive to your
cooling system, remember:
- We re commend using on ly coola nt ad­
d itive G 12++ or G 13 for your veh icle .
T his coolan t ad di tive is availab le a t au­
thor ized Audi dealers. Other types of
antifreeze can significantly reduce cor ­
rosion protection. The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage .
- Do not add any type of rad iator leak seal­
ant to your vehicle's engi ne coolant .
Add ing radiator repa ir flu id may adverse ­
ly affect the f unction and performance of
your cooling system and cou ld resu lt in

pressure relie f valve in the cap when the en­
gine becomes hot.
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.
