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.

148 This
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.

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

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-----------------------
Operate your vehicle safely
The condition of the vehicle is es­
sential for driving safety.
Therefore, always be sure to observe the
following points before you drive off:
• Check lights and turn signals.
• Check fuel level.
• Adjust the mirrors.
• Make sure that all lights and all
windows are clean.
• Make sure the air Intake slot be­
tween the engine hood and the
windshield is free of leaves, snow
and ice.
• Check warning and indicator
lights when starting the engine.
For driving safety, always follow the speci­
fied maintenance intervals in your Mainte­
nance booklet -especially for changing
the brake fluid, see page 242.
Yo ur personal driving style and your
attitude affect driving safety to a
very great extent.
19 4 Therefore,
for your own safety:
• Wear your safety belts and wear
them properly, even if you're just
driving in the city or to the corner
store -see page 14.
• Make sure that all passengers are
wearing their safety belts properly,
even those sitting in the rear -
see page 14.
Passengers not wearing safety belts endan­
ger not only themselves in case of an acci­
dent, but also the driver and other passen­
gers.
• Make sure that children always sit
on the rear seat properly restrained
by a res traint system appropriate
for their size and age.
• Never transport a child in a rear­
facing child or infant seat on the
front passenger seat.
• Adjust your seat so that you can
easily reach all controls as far away
from the airbag as possible but no
closer than 10 in. (25 em) -
see page 76. •
The seating position is very im­
portant for the airbag performance
- see page 29.
• Always adjust the head restra ints
to the correct height.
For maximum protection, the upper edge of
the head restraints should be at least at
eye level, or higher .
• Always make sure that the move­
ment of the pedals is not restricted
In any way-see page 102.
• Store luggage and light items
properly
in the luggage compartment ­
see page 88.
of the roof - see page 191.
• If you drink, do not drive.
The use of alcohol, drugs and certain medi­
cations will seriously impair perception,
reactions and driving ability, and substan­
tially increase the risk of an accident and
personal injury.

VE
HICLE OPERATION------------------------
The external conditions
in which you drive also affect your fuel con­
sumption.
The following conditions increase fuel con­
sumption:
• Heavy traffic, especially in large cities
with many traffic lights.
• Stop-and-go driving, especially short dis­
tances so that the engine never warms up
as it should.
• Driving in heavy, slow moving traffic in
low gear so that the engine speed is rela­
tively high when compared to the distance
driven.
� Plan your trips ahaad of time. Or­
� ganizs your trips to include sev­
sral errands and to avoid heavy traf­
fi c.
Of course, there are some conditions that
will affect fuel consumption that you can't
control.
For example, fuel consumption increases in
the winter or under difficult conditions (bad
roads, towing a trailer, etc.).
19 6 The
technical requirements
for optimum fuel consumption and eco­
nomy were ''built" intoyourvehicle. Special
attention was paid to the environment. To
reta in and make use of these characteris­
tics, please note the following points:
riJ Use only unleaded gasoline.
Leaded gasoline causes damage to the cat­
alytic converter and other components of
the emission system.
t:Gh Have your vehicle serviced by an
� Audi Dealar at the specified in­
tervals -see page 228 and your
Main tenance booklet.
Having your vehicle regularly serviced by an
Audi Dealer helps ensure that it runs prop­
erly and economical ly, that it does not dis­
turb the environment, and that it has a long
service life. t:Gh
Check
your tire pressure once a
W month.
Low tire pressure increases fuel consump­
tion and tire wear, and impair s vehicle han­
dling.
�W ARNING
Underinflation and overloading of
tires can lead to tire failure. Sud­
den failur e on the road could cause
a serious or fata l accident. See
page 253 for inflation informa­
tion.
� Do not carry unnecessary items
in the luggage compartment.
Particularly in city traffic where you must
often accelerate, weight influences fuel
consumption.

----------------------VEHICLE
OPERATION
,:lib Remove
supplementary roof
� rack components when not In
use.
At high road speeds, the increased air �e­
sistance caused by the cross bars also In­
creases fuel consumption.
,:lib Switch oH any electrical equip­
� ment when no longer needed.
The more electricity you consume, the
higher the fuel consumption.
,:lib Check your vehicle 's fuel co?­'l!�Sr sumption regularly. Keep a writ­
ten record or use the trip odometer .
Check your fuel consumption ea?h time you
refu el. By doing this, you can d1scov �r a �y
inc onsistencies which could result 1n In­
creased fuel consumption and have these
checked before other problems appear. •
Check your oil each time you fill
your tank
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a cer­
tain mileage has been driven.
You must drive your vehicle about 3,000
miles (5 000 kilome tres) before you can
properly assess oil consumption.
This also applies to fuel consumption and
engine output.
• The published ENVIRONME NTAL
PROTECTION AGENCY (EPA) and
Tr ansport Canada consumption esti­
mates may not correspond to your
actual consumption on the road.
which will vary depending upon ve­
hicle load and speed. road and
weather conditions. trip length. etc. The
catalytic converter is an efficient
"clean-up" device built into the exhaust
system of the vehicle. The catalyttc convert­
er burns many of the pollutants in the ex­
haust gas before they are released into the
atmosphere.
The exclusive use of unleaded fuel is
critically important fo.r the life of
the catalytic converter and proper
functioning of the engine - see
page 225.
The catalytic converter will be per­
manently damaged by:
• Exc eeding the correct engine oil
level - see page 236;
• Driving until the fuel tank be­
comes completely empty. The en­
gine could misfire. Unburned fuel
could also get into the exhaust sys­
tem and this could cause the catalyt­
ic converter to overheat;
