The indicator light will come on when the
ignition is switc hed on. It should go out after
the engine starts. If
the engine management system experi­
ence trouble while you are on the road, the
indicator light will come on to alert you. The
electronic engine power control system will
automatically switch to the failure-mode
program. You will experience some reduc­
tion in engine power. Drive the vehicle to an
authoriz ed Audi Dealer as soon as possible. Side
marker lights I ;o�
head lights
The light comes on when the side marker
lights or head lights are switched on with
the ignition on.
Self-lev eling
suspension
The warning light will come on when you
switch on the ignition, and will then go out
after a few seconds just as a test to make
sure the light is working properly.
If the warning light blinks after the function
test, this means that the vehicle's ride
height has dropped down. It's normal for
this happen, for example, after the vehicle
has been parked for some time.
The warning light will go off after the self­
leveling suspension has re-adjusted the ve­
hicle ride height. After this has taken place,
the vehicle will now be at its original ground
clearance regardless of cargo load.
Do not drive off until the warn ing light stops
blinking, otherwise you could damage low­
mounted parts on the rear suspension if you
drive over uneven road surfaces.

WARNING continued
• If the brake warning light does
not go out with the engine running
and the parking brake released, or
lights up while you ere driving, the
fluid level in the brake fluid reser­
voir is too low.
• If you believe that it Is safe to do
so, proceed immediately at low
speed to the nearest authorized
Audi Dealer or qualified workshop
and have the brake system in­
spected.
• Please be very careful and be
sure to remember that after sev­
eral brake applications, you will
need greater pressure on the brake
pedal to stop your vehicle. Conse­
quently, you must allow for in­
creased braking distances. Trying
to brake as quickly as usual could
lead to an accident.

This
light comes on when the ignition is
turned on and goes out after the engine is
started. If the light does not go out after
star ting and rewing up the engine momen­
tarily or lights up while driving, there may be
a malfunc tion in the electrical system, or the
V- belt driving the gener ator may be broken. A If the warning light comes on
V while driving, stop the vehicle
and turn oft the engine. Inspect the
belts.
If the V-belt is not torn, you can still continue
driving to the nearestAudi Dealer. However,
since the battery is no longer being charged,
switch off all unne cessary electrical equip­
ment.
If the V- belt is tom, the power steering and
the radiator fan will also not work.

On Board Diagnostic system
The Malfunction Indicator Lamp (MIL)-see
page 125- is part of the On Board Diagnos­
tic system (OBD).
The lamp comes on when the ignition is
swi tched on and will go out after the engine
is started and the idle has stabilized. This is
to assure you that the Malfunction Indicator
Lamp is working properly.
If the lamp does not go out after the engine
is started, or if it comes on while you're
driving, there is a malfunction in the engine
system. If the lamp starts blinking, the cata­
lytic converter could be damaged.
Continue driving with reduced power
and have the cause corrected right away by
an authorized Audi Dealer or a qualified
workshop.
12 8 If the lamp comes
on, the Electr onic speed
li miter can also be out of operation. See
next page.
The On Board Diagnostics in your vehicle
monitors the various components of your
emission control system. Each controlled
component in your engine system has been
coded. In case of a malfunction the respec­
tive component in question will be identi­
fied and the fault stored in the form of a
code in the control module's memory.
On Board Diagnostic
System (OBD)
The stored data can only be displayed with
special testing equipment (generic scan
tool for OBDl to assure an accurate diagno­
sis.
To connect the special testing equipment,
push the plug into the Data Link Connector
(DLC) located to the right of the release le­
ver for the engine hood -see illus tration.
Yo ur authorized Audi Dealer or a quali fied
workshop can interpret the code and make
the necessary correction.

Electronic
speed limiter
Yo ur Audi may be factory equipped with
tires which are rated for a maximum speed
of 130 mph (21 0 km/h). This is less than the
maximum speed of your vehicle. To reduce
the risk of sudden tire failure and loss of
control should the vehicle be operated at ex­
cessive speeds, your Audi also has an elec­
tronic speed limiterwhi ch prevents your ve­
hicle from going faster than the tire speed
rating. See page 257.
If the vehicle approaches the tire speed rat­
ing, the engine control unit will shut off the
fuel injectors and you will notice an instant
Joss of engine power and drop in road
speed. The engine performance will return
to normal as soon as the speed has dropped
below approximately 125 mph (200 km/h).
If the vehicle road speed signal to
the engine control unit should fail,
the Malfunction Indicator Lamp will
come on.
If this occurs, see your authorized Audi
Dealer and have the cause located and cor­
rected. �W
ARNING
Always observe the posted speed
limits and adjust your speed to suit
preva iling road, traffic and
weather conditions. Never drive
your vehicle faster than the maxi­
mum speed rating of the tires
installed. CONT

�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.

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.

switch also operates the front and rear
fog lights: it can pulled out when the side
lights or headlights are switched on.
To conserve battery power, the headlights
will go out automatically when the ignition
is turned off or while the starter is engaged.
High beam, low beam and headlight flasher,
see page 156.
Automatic headlight adjustment
After you start the engine, as well as while
the vehicle is moving, the headlights auto­
matically adjust themselves to the load and
angle of the vehicle (for example, during ac­
celeration or braking). This prevents unnec­
essary glare for on-com ing traffic.
If the system is not operating properly, the
warning symbol in the Auto Check Control
- see page 144- will come on. Daytime
running lights
(Canada models only)
When the ignition is switched on, the fog
lights, side marker lights and taillights will
automatically come on.
�W ARNING
Accidents can happen when you
cannot see the road ahead and
when you cannot be seen by other
motorists.
- Never use daytime running
lights to see where you're go­
ing. They are not bright enough
and won't let you see for enough
ahead for safety, especially at
dusk or when it's dark.
- Always turn on the headlights
so that you can see ahead and so
that others can see your car
from the back.

ROLS AND EQUIPMENT
The above illustration shows the outlets at
the rear of the center console.
Air is directed to these outlets automati­
cally.
The heater outlets for the rear footwall are
located under the front seats. They are con­
trolled together with outlet 5.
16 6 Solar
roof*
On models with a solar sliding roof, if the ve­
hicle is parked in sufficiently strong sunlight
and the ignition has been turned off, the
blower automatically switches to the solar­
powered mode. The blower motor runs on
solar energy, keeping the vehicle's interior
supplied with fresh air.
For optimum air delivery the center (4) and
the side dashboard vents (3) should be
opened.
The solar -powered fan only works when the
sliding roof is closed or raised open at the
rear.
If the ventilation system happens to be set
to the recirculate mode, the climate control
system automatically switches to the fresh
air mode. Key
coding
To achie ve maximum comfort levels, the
current manual settings for the air condi­
tioning system are automatically saved.
For example, if the air conditioning settings
were changed when someone else used
your car, the air condition system will auto­
matically be reset to the settings that match
your key when you turn on the ignition
again.
This assumes that the previous driver used
a key other than yours. If the previous driver
used your key, his or her new settings
would be assigned to your key.
If a number of persons use the vehicle, then
if possible, each should use a different key.
In this way, your personal air conditioning
set ting will be restored automatically.

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.
