• If you must work underneath
the vehicle with the wheels on the
ground, always make sure the ve­
hicle is on level ground. that the
wheels are always securely
blocked and that the engine can­
not be started. Always remove the
ignition key before anyone gets
under the vehicle.
Always make sure the transmis­
sion selector lever (automatic
transmission) is in "P" (Park posi­
tion) and the hand brake is firmly
applied.
• Always be extremely careful
when working on the vehicle. Al­ways follow commonly accepted safety practices and general com­
mon sense. Never risk personal in­
jury.

Changing the engine settings
will adversely aHect emission
levels. This Is detrimental to the en­
vi ronment and increases fuel con­
sumption.
Always observe environmental reg­
ulations when disposing of old en­
gine oil. used brake fluid, dirty en­
gine coolant, spent batteries or
worn out tires.

When
adding fluids, always make
sure that they are poured into the
proper container or filler opening,
otherwise serious damage to ve­
hicle systems will occur. r:Gb To detect leaks in time, inspect
� the vehicle floor pen from under­
neath regular ly. If you see spots
from oil or other vehicle fluids, have
your vehicle inspected by an autho­
ri zed Audi Dealer .

Engine cooling system
The cooling system is sealed and generally
requires little attention.
The cooling system has been filled at the
factory with a permanent coolant which
does not need to be changed. The coolant
consists of a mixture of water and the
man ufacturer's coolant additive G 12 ABD
-ant ifreeze on a glycol base with anti-corro­
sion additives (50% for USA models; 60o/o
for Canadian models). This mixture assures
the necessary frost protection and protects
alloy components in the engine's cooling
system from corrosion and scaling. It also
raises the boiling point of the coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The proportion of coolant additive
must be at least 500fa but not more
than 600fa to maintain antifreeze protec­
tion and cooling efficiency.
238 For
year-r ound driving, antifreeze is added at
the factory for temperatures down to:
-31 °F (-35 °C) USA
-40 °F (-40 °C) Canada.
g Always heed all WA RNINGS
E!!1 on page 232.
Never use eny coolant additive
other than our G12 ABD additive
(check label) for your vehicle. This
coolant additive is available at au­
thorized Audi Dealers.
Other types of antifreeze can. above
all. significantly reduce corrosion
protection. The resulting corrosion
can cause a loss of coolant and
therefore serious engine damage. When
adding coolant additive to
your cooling system. please remem­
ber:
Under no circumstances may G12
ABD be mixed with other coolant ad­
ditives (for example G 11 ).
You can recognize G12 ABD in the
expansion tank by its red color. If
the liquid in the expansion tank is
brown, G 12 ABD has been mixed
with another coolant additive. In
this case. your vehicle's coolant
must be changed as soon as pos­
sible.
Note
Mixing coolant additives can result
in serious malfunction or engine
damage!

Checking the
engine coolant
level
The coolant expansion tank is located on the
left of the engine compartment -see il­
lustration.
The coolant level is automatically monitored
by the Auto-Check System -see page 141.
However, it is still recommended to check
the coolant lev�l visually from time to time
and always before going on a longer trip.
�W ARNING
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 carefully
opening the hood and following
the precautions on the next page.
Always heed all WA RNINGS
on page 232. To
obtain an accurate reading, the engine
must be switched off.
Since the expa nsion tank is transparent, the
cap need not be removed to check the cool­
ant level.
The coolant level must be between the
"MIN" and "MAX" marks when the en­
gine is cold and can be slig htly above the
"MAX" mark if the engine is warm. VE
HICLE CARE
The expansion tank in your vehicle is
equipped with an electric coolant level
checking device.
When the coolant level is too low, the warn­
ing light (see page 141) in the Auto-Check
System will blink until you add coolant and
the coolant level has been restored to nor­
mal.
Coolant losses
Coolant losses may indicate a leak in the
cooling system. In the event of coolant
losses, the cooling system should be in­
spected immediately by your authorized
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 overheating.

VE
HICLE CARE
Adding coolant
� WARNING
The cooling system is under pres­
sura and can get very hot. Reduce
the risk of scalding from hot cool­
ant by following these steps.
• Turn off the engine and allow it
to cool down.
• Protect face, hands and arms es­
caping fluid and steam by covering
the cap with a large, thick rag.
• Turn the cap slowly and very
care fully in a counter--clockwise di­
rection while applying light, down­
ward pressure on the top of the
cap.
• To help avoid being burned, do
not spill antifreeze or coolant on
the exhaust system or hot engine
parts. Under some conditions, the
ethylene glycol in engine coolant
can catch fire.
240 If,
in an emergency, only water can be add­
ed, the correct ratio between water and an­
tifreeze (see page 238) must be restored as
soon as possible.
If you have lost a considerable amount of
coolant. then you should add cold antifreeze
and cold water only when the engine is cold.
Do not fill coolant above the "MAX"
mark.
Note
Coolant pollutes the environment
and could cause an engine fire. Ex­
cess coolant will be forced out
through the pressure relief valve in
the cap when the engine becomes
hot. Screw cap
on again tightly.
� WARNING
Antifreeze is poisonous. Always
store antifreeze in its original con­
tainer and well out of the reach of
children. If you drain the coolant,
it must be caught and safely
stored in a proper container
clearly marked "poison ...
<£> Drained coolant should not be
reused. Always dispose of used
coolant observing all env ironmen­
tal regulations.
Always heed all WARNINGS
on page 232.

Radiator
fan
The radiator fan is driven by the engine via
the V-belt. The viscous clutch regulates the
speed of the fan according to the tempera­
ture of the coolant.
An auxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operation conditions.
� WARNING
• Always use extreme caution to
prevent clothing. jewelry, or long
hair from getting caught in the en­
gine driven radiator fan, V-belt or
other moving parts.
• Never touch the auxiliary elec­
tric radiator fan. The fan can
switch on suddenly and injure you.
Always heed all WA RNINGS
on page 232. Power
steering
Yo ur vehicle is equipped with a Servotro­
nic power steering. The degree of
power assistance is regulated electronically
according to road speed.
The fluid reservoir is in the engine compart­
ment near the windshield washer container.
The correct fluid level in the reserv oir is im­
portant for the proper functioning of power
steer ing.
The power steering fluid level is checked
during the scheduled Maintenance ser­
vices.
If the electronic regulating system is not
working properly, this is most noticeable
when turning the steering wheel at low
speeds (for example when parking) -more
effort will be required than usual. The fault
should be rectified by an Audi Dealer as
soon as possible. VEH
ICLE CARE
Note
• When the engine is running, never hold
the steering wheel turned all the way to the
right or to the left for longer than 15 sec­
onds. The power steering pump will over­
heat the hydraulic fluid if you hold the steer­
ing wheel all the way turned.
This will damage the power steering
system.
Each time the steering wheel is turned all
the way to the right or left when stopped,
you will hear noises caused by the severe
stress placed on the power steering pump.
At the same time, engine idle speed drops.
• If the power steering system
should fail, or if the engine is not
running (for example, while being
towed). you will still be able to steer
the vehicle, however. more effort
will be required.
• If the power steering system should
have a leak, or is not functioning properly,
contact your authorized Audi Dealer imme­
diately.

Windshield I headlight washer container
The windshield and headlight washer con­
tainer is located on the left side of the en­
gine compartment.
The fluid container for the windshield wash­
ers and the headlight washer system holds
about 4.9 quarts (4.7 liters).
A Always heed all WAR NINGS
� on page 232.
250 Filling
the container
To add washer fluid, just lift the filler cap by
the tongue. The container can be filled to
the top.
Since clear water is usually not adequate for
cleaning the glass, add a cleaning solution
to the water.
Use winterized windshield washer solvent
during the cold season even though the ve­
hicle is equipped with heated washer
jets. It helps to keep your windshield clean
and prevents the fluid from freezing in the
winter.
Do not use engine coolant anti·
freeze or any other solution that can
damage the vehicle paint.
Follow the directions on the can for the cor­
rect amount to be used.
After filling the container, press the cap onto
the filler neck. Adjusting
washer jets
You need special equipment to adjust the
jets for the windshield and the headlight
washer system. See your authorized Audi
Dealer.
