-Always keep in mind that after several
brake applicat ions, you will need greater
pressure on the brake pedal to stop your
vehicle . Do not rely on strained brakes to
respond w ith maximum stopp ing power
in critical situations. You must a llow for
increased bra king distances. The extra
distance used up by fad ing brakes could
lead to an acc ident .
PARK /(®) Electromechanical parking
brake
The warning/indicator light monitors the
electromechanical parking brake .
If the indicator light - (USA models) ;II
(Canada models) turns on, the park ing brake
was set. If the parking brake is set when the ignition is
off, the indicator light turns off af
ter about 20 seconds .

-L Engine cooling system malfunction
A malfunction in the engine cooling system
must be repaired as soon as possible.
• Switch off en gine and che ck cool ant le vel
If the indicator light turns on and the mes
sage appears, the coolant temperature is too
high or the coolant level is too low.
.. Pull
off the road .
.. Stop the vehicle .
.,. Turn
off the engine .
.,. Check coolant leve l~
page 22 7 .
.. Add coo lant if necessary ~
page 228.
.,. Continue dr iv ing on ly after the engine cool
ant warning/indicator light goes out .
.. Contact your authorized Audi dealer for as-
sistance if necessary.
If the engine coo lant level is correct, then the
radiator fan may be the ca use of the malfunc
tion .

~ fig. 170. This releases th e catch.
... Open the hood.
&_ WARNING
Hot engine coolant can burn you.
- 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 .
' Working in the engine compartment
Be especially careful whenever you work in
the engine compartment.
Whenever you must perform any work in the
engine compartment, for example checking
and filling different fluids, there is a risk of injury, burns and accidents. To prevent per
sonal injury always observe the following
WARNINGS. The engine compartment of any
vehicle is a hazardous area
~ ,&. .
/n.. WARNING
To help avoid injury, before you check any
thing under the hood:
- Turn off the engine.
- Switch off the ignition .
- Apply the parking brake.
- Move selector lever to "P" (Park) .
- Always let the engine cool down. Hot
components will burn skin on contact.
- 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.
- If work on the fuel system or the electri
cal system is necessary:
- Always disconnect the battery.

cold engine, the coo lant level should be be
tween the "min" and "max" markings. When
the engine is warm, the level may be s light ly
above the "max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration
r:::;, page 222.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check System
r:::;, page 16 will
i l lum ina te unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time.
Coolant los s
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
sea led system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction wh ile ap
plying light, downward pressure on the
top of the cap.
- To avoid be ing burned, do not spill ant i
freeze or coolant on the exhaust system
'
or hot engine parts. Under certain cond i
tions, the ethylene glycol in engine coo l
ant can catch fire.
(D Note
Do not add any type of radiator leak sea l
ant to your vehicle's engine coolant. Add i ng radiator repa ir fl uid may adverse ly af
fect the funct ion and performance of your
cooling system and could result in damage
not covered by your New Veh icle L imited
War ranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the eng ine com
partment,
always read and heed all W ARN

Replacement engine coo lant must conform to
exact spec ificat ions
r:::;, page 22 7, Coolant.
E ven in an emerge ncy, if coolant add i-
t ive G12 ++, G 12+ or G12 is not available, do
not use a d iffe rent additive. Use plain water
instead unti l you can get the correct additive
and can restore the correct ratio . This shou ld
be done as soon as possible.
If you have lost a considerab le amount o f
coolant, then you sho uld add cold antifreeze
and co ld water on ly w hen the engine is cold.
Always use
new engine coo la nt when refilling.
Do not fill coola nt above the "MAX" mark . Ex
cess coola nt will be fo rced out through the
pressure relief valve in the cap w hen the e n-
gine becomes hot. .,.

_& WARNING
-The cooling system is under pressure and
can get very hot. Reduce the risk of
scald ing from hot coolant by following
these steps.
- Turn
off the engine and a llow itto cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slow ly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spi ll an
tifreeze or coolant on the exhaust sys
tem or hot engine parts . Under certain
conditions, the ethylene glycol in en
g ine coolant can catch fire .
- Antifreeze is poisonous. Always store an
tifreeze in its or iginal containe r 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 clearly marked "poison".
(D Note
- Coolant pollutes the env ironment and
could cause an engine fire. Excess cool
ant will be forced out through the pres
su re relief valve in the cap when the en
gine becomes hot.
- If, in an emergency, only water can be
added, the cor rect ratio between water
and antifreeze ¢
page 227 must be re
stored as soon as possib le.
@ For the sake of the environment
Drained coolant should not be reused . A l
ways dispose of used coolant while obse rv
ing all environmental reg ulations.
Checkin g and fillin g 229
Radiator fan
The radiator fan switches on automatically by
itself.
An auxiliary electric radiator fan switches on
and
off depending on coolant temperature
and other vehicle operat ing cond it ions .
After you switch the engine
off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition
off. It can even switch
on again later by itself ¢&. , if
- the temperature of the engine coo lant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment 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
controlled and can sw itch on suddenly
even when the engine is not running.
- The a uxiliary radiator fan sw itches on au
tomatically when the engine coo lant
reaches a certa in temperature and will
continue to ru n until the coolant temper
ature drops.
