�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.
Refer to "Coolant temperature gauge" on
page 118 for detai ls.

14 4 Speed
warning
You can store a road speed which is not to
be exceeded. As soon as you exceed that
speed by approximately 6 miles (1 0 kilome­
ters), a warning tone sounds and "MPH"
("k m/h ") appears in the disp lay.
Nota Always monitor the vehicle speed by
means of the speedometer. The speed
warning device may only be used as a re­
minder not to exceed the posted speed
limit. The
following describes how to store or de­
lete speed warnings 1 and 2.
Speed warning 1
The ''MPH" ("km/h ") disappears when you
reduce the speed below the stored speed.
Also, the ''MPH" goes out when the driving
speed increases approximately 25 mph
(40 km/h) over the set speed for at least
1 0 seconds. The stored speed is not de­
leted.
Selec ting speed limit
Press the test button for the Auto-Check
control briefly when the desired speed is in­
dicated on the speedometer. The speed
warning symbol lights up when the button
is released to confirm that the selected
speed has been stored.
The set speed limit remains stored until
another speed is selected by pressing the
button again or until the memory is cleared.

1/1 00 km -Instantaneous
(MPG) fuel
consumption
Fuel consumed instantaneously IS mea­
sured every 1 00 feet or 30 meters and dis­
played in units of miles per gallon (MPG) or
liters per 100 kilometres (1/1 OOkm). When
this function is selected right after engine
start -up, the display will show the average
fuel consump tion figure for the first 100
feet or 30 meters. When the vehicle is sta­
tionar y, the last unit measured will be dis­
played.
km -Kilome tres or miles to
{Mi) empty
The displa yed information (indicated in
stages of 5 miles or 1 0 kilometres) is based
on the average fuel consumption computed
during the last 20 miles or 30 kilometers. This
feature informs the driver how many
miles or kilometres of normal and smooth
driving can be covered with whatever
amount of fuel remains in the tank. Fuel
economy is the result of good driving habits.
h Driving time
Driving time elapsed will remain in storage,
even pfter the ignition is turned off. Further
driving time will be added automat ically af­
ter engine restart. Maximum storage and
display range is 23 hours: 59 minutes. To
keep track of driving time between points,
depress "Reset" for zero.
Driving time alert
While driving, the computer will automati­
cally switch to the "driving time" display ev­
ery two hours. The indicator "2:00" (or
"4:00", "6:00", "8:00" etc.) will blink in the
display window to alert the driver to take a
break. The blinker can be turned off briefly
by pushing "Reset'' or either side of the
switch. If the
ignition is off more than ten minu tes,
the driving time alert counter will automati­
cally start again from zero. If the ignition is
off less than ten minutes, the display will
blink again every two hours.
0 I (MPG) -Ave rage fuel

The display will show the computed aver­
age since the last "Reset". When the igni­
tion is turned off, the computed average re­
mains in storage. When driving is resumed,
the computation continues automatically.
To delete stored data, push "Reset".
0 km/h -Average driving
(MPH) speed
The display will show the computed aver­
age of driving speed variations since the last
"R eset". When the ignition is turned off,
the computed average remains in stora ge.

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.

WARN ING
To avoid being struck by another
vehicle, move your vehicle a safe
distance off the road when stalled
or stopped for repairs. Do not park
or operate the vehicle in areas
where the hot exhaust system may
come in contact with dry grass,
brush, fuel spill or other material
that can cause fire.
When the airbag deploys in an accident, the
emergency flasher also will come on.

Manual mode
To switch from the automatic mode to the
manual mode, press button (1) or (3) for at
least 2 seconds. Press again to return to the
automatic mode.
The yellow LED in the display (2) will be lit
in the manual mode.
15 4 Increasing
the vehicle ride height
manually
To make certain that the system functions
properly, do not raise the vehicle ride height
unless the engine is running.
Press button (3) to adjusting the vehicle to
the next higher level, ending at the high
laval.
Once you are in the high level, you can go to
the highest laval by pressing the button
again.
Levels that have been selected but not yet
reached by the vehicle are indicated by flas­
hing LED's in the level indicator (2).
The current actual level is indic ated by conti­
nuously lit LED's.
Manually lowering the ride height
Press button (1) to go to the next lower
laval. You can repeat this until you've se­
lected the low level.
The next level that was selected but has not
been reached by the vehicle is indicated by
a continuously lit LED in the level indica­
tor (2).
The current actual level is indic ated by flas­
hing LED's. Notes
• The control operations are dependent on
the vehicle's current speed. For example, it
is not possible to manually switch to the
·high level or highest level when the vehicle
is going above a cert ain speed.
Likewise, if ·you. have already selected the
high or highe st level, and the vehicle speeds
up above a certain speed, the system auto­
matically switches down to the next lower
level.
For example, at about 20 mph (35 km/h) the
vehicle will lower from the highest level to
the high level. Beginning at about 50 mph
(80 km/h), the system switches from the
high level to normal level.

Headlight flasher
You can signal with your headlights by pull­
ing the lever toward the steering wheel.
When flashing headlights, the blue indicator
light will come on. Xenon
lights*
After starting the engine the Xenon head­
ligh ts are automatically adjusted to the load
and angle of the vehicle (for example, during
acceleration, braking). This prevents on­
coming traffic from experiencing unneces­
sary glare from your headlights.
If the system is not operating properly, a
warning symbol will be displayed in the
Auto Check Control -see page 144. CONTROLS
