~ Contact your authorized Audi dea ler for as -
sistance if necessary.
If the engine coolant level is co rrect, then the
radiator fan may be the cause of the malfunc­
tion.
If the generator wa rning/ind icator light
should also illuminate
r:!:> page 16, then the
fan belt may be damaged.
A WARNING
- If your vehicle should break down for
mechanical or other reasons, park at a
safe distance from moving traffic, turn
off the engine and turn on the hazard

your eng ine.
@ Electro-mechanical power assist
If the indicator lig ht illuminates w hile you are
driving, there is a malfunction in the electro­
mechanical steering. If the ind icator light is
show ing ,£"~ . there may be a reduction in pow­
er steering assist. If the ind icator light is
show ing . , there may be a total loss of pow­
e r steering assist. The stee ring m ust be in­
spected immediately by a qua lified wor kshop
¢ ,&. .With the engine no t running (e.g. when
the car is being towed), there is a lso no power
assist avai lab le .
A WARNING
-
If there is a ma lf u nction, the indicator
light for the electro-mechanical power as­
sist illuminates. Seek professional assis­
tance.
~ Clutch pedal
App lies to vehicles: wit h manual transmiss ion
T he ind icator light [~l ill uminates if you do
not press the clu tch pedal when s ta rting the
engine. For safety reasons, the eng ine will on ­
ly start when the clutch peda l is pressed.
;;,I C; Electronic Stabilization Control
(ESC)
If the hJ indicator lamp blinks while dr iv ing,
the ESC or ASR (Anti-Slip Regu lation) is active ­
ly regulating .
If the
G! indicator lamp illuminates, the sys­
tem has switched the ESC off. In th is case, you
can switch the ignition off and then on to
switch the ESC on again. The system is func­
t ion ing complete ly when the ind icator lamp
swi tches off.
If the
I) indicator lamp illuminates, the ESC
was switched off w ith the
[ru button .
Stabilization program and AB S fault! See
owner 's manual
If the G! indicator lamp and the [I] ABS indi­
cator lamp illum inate and the driver message
appears, the ABS or electron ic different ia l lock
is malfunct io ning . This also interrupts the
ESC. The brakes still function with their nor ­
mal power, but ABS is not active.
Drive to your authori zed A udi dealer immedi­
ate ly to have the malfunction corrected .

-Apply the parking brake.
- Move selector lever of automatic trans-
mission to "P" (Park); put manual trans­
mission in Neutral.
- 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 .
- 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:
Checking and filling 181
- First, fully apply the parking brake,
move selector lever of automatic trans­
mission to "P" (Park); put manual
transmission in Neutral.
- 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 wear no clothing that will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~,& .
.8, 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.
(D 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 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
id s, have your vehicle inspected by an au­
thorized Audi dealer . •

188 Checking and filling
Before you check anything in the engine com­
partment,
alwa ys r ea d and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 180.
• Park your vehicle on a level surface.
• Switch the ignition off.
• Read the coolant level at the coolant expan­
s ion tank ¢
page 182, fig . 134. With a cold
engine, it must be above the "min" mark .
With a hot engine, it ca n be a little above
the indicated range .
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration
¢ page 182.
To obtain an accurate read ing, the engine
must be switched off.
The expansion tank in yo ur vehicle is equipped
with an e lectric coolant level sensor .
When the coo lant level is too low, the warning
light in the A uto- Check System ¢
page 16 will
illuminate until yo u add coo lant and the level
has been restored to normal. Even though
there is an electric coo lant level sensor, we
still recommend you check the coolant leve l
from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cool­
ing system should be inspected immediately
by your author ized Audi dealer. It is not
enough merely to add coolant .
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
(D Note
Do not add any type of radiator lea k seal­
ant to your vehicle's eng ine coolant. Add­
ing radiator repair f luid may adversely af­
fect the function and performance of your
cooling system and could res ult in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 180 .
• Turn off the engine.
• Let the engine cool down.
• Place a thick rag over t he coo lant expansion
tank
¢ page 187, fig . 138 a nd carefully
tw ist the cap counter-clockwise ¢&_ .
• Add coo la nt.
• Twis t the cap on aga in
t ightly.
Replacement engine coolant must conform to
exact spec ificat ions ¢
page 18 7, Coolant.
Even in a n emerge ncy, if coolant add i-
t ive G1 2++, G12+ or G12 is not ava ilable , do
not use a d iffe ren t addit ive. Use plain water
instead unti l you can get the cor rect additive
and can restore the correct ratio . This sho uld
be done as soon as possible .
If you have los t a considerab le amount o f
coolant , then you sho uld add cold ant ifreeze
and co ld wate r on ly w hen the engine is cold.
Alw ays use
new engine coo la nt whe n refilling .
Do not fill coola nt above the "MAX" mark. Ex­
cess coola nt wi ll be fo rced o ut through the
pressure relief valve in t he cap w hen the en­
gine becomes hot.
,&. WARNING ~ -
- T he cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by followi ng
these steps.
- T urn off the engine and allow it to coo l
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering
the cap w ith a large, t hick rag.
- T urn the cap s lowly a nd ve ry carefully
in a counter-clo ckwise direction while
applying light, downward pres sure on
the top of the cap.

-To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­ tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
tifreeze in its original container and well 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 environment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze¢
page 187 must be re­
stored as soon as possible.
@ For the sake of the environment
Drained 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 electric radiator fan is controlled by ther­
moswitches that switch on and off depending
on coolant and engine compartment tempera­
tures.
An auxiliary electric radiator fan* switches on
and off depending on coolant temperature
and other vehicle operation conditions.
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
c::> &., , if
- the temperature of the engine coolant rises due to the heat build-up from the engine in
the engine compartment, or
Checking and filling 189
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.

Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS c::> .&. in Working in the engine compart­
ment on page 180.
~ Read the brake fluid level from the brake
fluid reservoir
c::> page 182, fig. 134 . The
brake fluid level must be between the "MIN"
and "MAX" markings.
The brake fluid reservoir is located behind the
rear partition of the engine compartment on
the left side
c::> page 182.
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads. This is not cause for alarm.
