temperature gauge
The needle in the coolant temperature
gauge will indicate the temperature of the
coolant when the ignition is switched on.
Engine cold
Avoid high engine speeds and heavy
throttle when the needle is still at the left of
the dial.
Normal temperature
During normal running, the needle will re­
main somewhere in the middle of the dial.
If the engine is working hard at high outside
temperatures, the needle may also go fur­
ther to the right, but this Is no cause for
concern as long as the coolant tem­
perature warning light does not
flash.

ROLS AND EQUIPMEN T-------------------------------------------
Radio frequency display
If the radio is switched on and no second
priority faults are present, the OK symbol
will go out and the display will show the fre­
quenc y selected and various other informa­
tion. This feature depends on the type of ra­
dio fitted.
These displays are in addition to the radio
display -see separate operating instruc­
tions for radio.
13 8 Auto-Check
system
In addition to the warning lights the Auto­
Check System consistently monitors cer­
tain individual functions and components of
the vehicle as soon as the ignition is turned
on and when the vehicle is moving.
Malfunctions or urgent repairs are audi bly
signaled as well as displayed by red (prior­
ity 1) or yellow (priority 2) light symbols in
the instrument cluster.
You are thus reminded that a problem exists
which should be corrected for your conve­
nience and safety, and to prevent the risk of
considerable damage to your vehicle due to
cert ain malfunctions.
The Auto-Check System incorporates a
speed warning feature and is also used
to display certain radio information_
The following malfunctions or warnings can
be displayed: Red Symbols (priority
1)
Engine coolant level is too low/
Engine temperature is too high
(moving symbol).
Engine oil pressure is too low
(moving symbol).

--------------------CONTROLS AND

If there are one or more faults, the driver in­
formation disappears about 15 seconds af­
ter the engine has been started and the ap­
propriate fault symbol appears in the
display.
If neither "OK" nor any other fault symbol
appear in the displa y, the auto-check sy­
stem must itself be checked. Displays
In case of a malfunction or component fail­
ure, the acoustic warning will sound and the

CONT
ROLS AND EQUIPMENT---------------------
�W ARNING
• The engine compartment of any
motor vehicle is a potentially haz­
ardous area. Before you check any­
thing in the engine compartment,
stop the engine and let it cool
down. Always exercise extreme
caution when working under the
engine hood. Heed all of the
WA RNINGS on page 232.
• To reduce the risk of being
burned, never open the hood if you
see or hear steam or coolant es­
caping from the engine compart­
ment. Wait until no steam or cool­
ant can be seen or heard before
carefully opening the hood.
• Never touch the radiator fan.
The auxiliary fan is temperature
controlled and can switch on sud­
denly.
14 2 �
WARNING continued
• Reduce the risk of scalding from
hot coolant by following these
steps:
If the coolant reservoir cap must
be removed. wait until the en­
gine has cooled down.
- Protect face, hands. and arms
from escaping fluid and steam
by cov ering the cap with a large.
thick rag.
Tu rn the cap slowly and very
carefully in a counter-clockwise
direction while applying light.
downward pressure on the top
of the cap.
- To help avoid being burned. do
not spill antifreeze or coolant on
the exhaust system or hot en­
gine parts. Under some condi·
tions. the ethylene glycol in en·
gine coolant can catch fire. •
If a visual check shows the coolant level
and the V-belt normal, and the warning light
still does not go out, do not continue
driving. See your authorized Audi Dealer.
• If the coolant level and the V-belt are nor­
mal, the malfunc tion may be in the auxiliary
radiator fan. You can continue driving to the
nearest authorized Audi Dealer. The wind
from the moving vehicle and the main radia­
tor fan driven by the V-belt will be enough to
keep the angine cool. However, avoid idling
for a long time or driving very slowly.
If the V-belt is torn, the main radiator fan, the
power steering and the gener ator will also
not work.
Obtain expert assistance.
Refer to "Coolant temperature gauge" on
page 118 for detai ls.

EQUIPMENT
General notes
• Vehicle heating is depend upon tne tem­
perature of the engine coolant -therefore,
your vehicle interior will warm uponly when
the engine has reached its operating tem­
perature.
When the ambient temperature is too low,
the fan only switches to high speed modes
when the coolant has reached a sufficiently
high temperature, or when the ® button
has been depressed.
• Keeping the air intake slots in front of the
windshield free from ice, snow and debris
helps to make sure that the climate control
system will work properly.
• When the air conditioner compressor is
on it reduces both the temperature and the
humid ity of the air inside the vehicle. This
prevents the windows from fogging up.
• The air conditioner works best with the
windows and power roof* closed. •
If the inside temperature is very high af­
ter the vehicle has been parked in the sun,
open windows and allow the hot air to es­
cape before switching on the air condi­
tioner.
• The dust and pollen filter will prevent
dust and pollen etc. in the outside air from
entering the car. Switch to air recirculation
to prevent unpleasant fumes from entering
the vehicle.
If water drips under the
vehicle ...
At high outside temperatures and humidity,
condensation may drip from the evaporator.
This is normal and does not indicate a leak.
If the airflow is not cool ...
• At low ambient temperatures the air con­
ditioner compressor switches off automati­
cally. The compressor cannot be switc hed
on again in this case, even by pressing the
AUTO button. •
The air conditioner may switch itself off
temporarily to ensure sufficient engine
cooling when the engine is running at full
load.
The air conditioner will also be switched off
temporarily in the kick-down function. See
page 109.
• Check the air conditioning fuse on the
fuse p imel -see page 27 4. Have it replaced,
if necessary.
• If you suspect that the air conditioner is
damaged, for instance after an accident,
switch to the ECON and have the system
examined immediately for leaks or other
damage.

VEHICLE OPER
ATION-----------------------
Driving Instructions
To obtain the best possible handling of ve­
hicle and trailer , please note the following:
• A "balanced" rig is easier to operate and
control. This means that the tow vehicle
should be loaded to the extent possible and
permissible while keeping the trailer as light
as possible under the circumstances.
Whenever possible, transfer some cargo to
the luggage compartment of the tow ve­
hicle while observing tongue load require­
ments and vehicle loading considerations.
• The higher the speed, the more difficult
it becomes for the driver to control the rig.
Do not drive at the maximum per­
missible speed. Reduce your speed even
more under unfavorable load, weather or
wind conditions - particularly when going
dow nhill.
210 Be
especially careful when passing other
vehicles.
Reduce vehicle speed immediately if the
trailer shows the slightest sign of swaying.
Do not try to stop the sway ing by accel erat­
ing.
Observe speed limits. In some areas
speeds for vehicles towing trailers are low­
er than for regular vehicles.
• Always apply brakes early.
When driving downhill, shift into lower gear
to use the engine braking effect to slow
down the vehicle. Use of the brakes alone
can cause them to overheat and fail. •
The coolant temperatura gauge
must be observed carefully. H the
needle nears the upper end of the
scale, reduce speed immediately
and/or switch off the air condi­
tioner.
If the coolant temperature warning
light in the instrument cluster starts
flashing in red, pull off the road,
stop and let the engine idle for about
2 minutes to prevent a heat build-up.

VEHICLE CA
RE----------------------------------------------------
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!

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.
