Warning light
If the coolant warning light m the Auto­
Check System (see page 141) flashes when
driving, the engine may be overheated be­
cause of low coolant level.
Note
Do not install accessories (addi­
tional lights or Insect screens. for
example) on top of the front bumper.
They may restrict engine cooling
and cause engine damage.
Always heed all WA RNINGS

The fuel gauge works when the ignition is
switched on.
The fuel tank capacity is approximately 18.5
gallons (70 liters).
When the needle reaches the red area
there is a reserve of about 2.4 U.S. gallon �
(9 liters) of fuel left in the tank. lime to re­
fuel.
The fuel pump symbol in the instrument
cluster lights up as an additional reminder to
refuel.
Never run the tank completely dry. See also

Operating controls
The functions are switched on and off by
pressing the buttons briefly. The indicator in
the button comes on when the function is
operating.
AUTO -Automatic
(standard setting)
The air temperature, air flow and air distribu­
tion are regulated automatically to achieve
and maintain the desired passenger
compartment temperature as quickly as
possible. The system compensates for
changes in outside temperature and for the
intensi ty of the sunlight entering the vehicle
automatically.
- + Temperature setting
The desired interior temperature can be pre­
set within a range from 64°F (18°C) to 84°F
(29°C). In the two extreme settings "LO"
and "HI" the system operates continuously
with maximum cooling or heating output, so
the temperature is no longer regulated auto­
matically. Swit
ching between Fahrenheit and
Centigrade
The temperature display can be
switched from oF to oc (and vice
versa) as follows:
Press Gill button and hold down. At the
same time press temperature selector but­
ton "+" on driver side briefly. @
-Defrost
In this mode, the windshield and side win­
dows will be defrosted I defogged as quick­
ly as possible.
The temperature is controlled automatical­
ly. Air flow will be on the maximum setting
and will mainly flow from outlets 1 and 2.
See "Air outlets" on pag e165.

AND EQUIP MENT
Air outlets
Depending on the operating mode se­
lected, the air flow to the outlets is con­
trolled either automatically or man ually.
The illust ration shows the air outlets in and
around the dashboard.
The outlets deliver either heated or un­
heated fresh air, or cooled air. I

2, 3 and 4 can be opened or
closed separately with the respective
thumbwheel next to the outlets.
The direction of air delivery from these
outlets can be adjusted horizontally and
vert ically. The upper outlets (2) are not ad­
justable.
Note
When the air conditioner is cooling the ve­
hicle interior, the cool air mainly emerges
from outlets 3 and 4. To ensure adequate
cooling, these outlets should therefore nev­
er be closed completely.

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 OPERA
TION-----------------------
Trailer towing
Yo ur Audi was designed primarily for pas­
senger transportat ion. The additional load
will affect durability, economy and perfor­
mance.
Tra iler towing not only places more stress
on the vehicle, it also calls for more con­
centration from the driver.
For this reasons, always follow the opera­
ting and driving instructions given and use
common sense.
208 Te
chnical requirements
Tr ailer hitch
Use a weight-carrying hitch conforming to
the gross trailer weight. The hitch must be
suitable for your vehicle and trailer and
securely bolted to appropriate place on the
vehicle's chassis. Use only a trailer hitch
with removable ball mount. Always check
with the trailer hitch manufacturer to make
sure that you are using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way
that it does not interfere with the impact-ab­
sorbing bumper system. No modifications
should be made to the vehicle exhaust and
brake systems. From time to time, check
that all hitch mounting bolts remain secure­
ly fastened. When
you are not towing a trailer, remove
the trailer hitch ball mount. This prevents
the hitch from causing damage should your
vehicle be struck from behind.
�W ARNING
When you are no longer towing a
trailer, remove the entire trailer
hitch. When doing so, seal all bolt
holes to prevent water and deadly
exhaust fumes from entering the
vehicle.
Engine cooling system
To wing a tr ailer make the engine work hard­
er. It is important that the engine cooling
system be up to the job. Make sure that the
cooling system has enough fluid.

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!

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.
239

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.
