Cruise
control
For your driving comfort the cruise control
system can be used to keep the vehicle
speed constant, as long as the engine pow­
er and braking are not affected, beginning at
about 25 mph (40 km/h).

ARNING
• To help keep the vehicle under
control, do not use the cruise con­
trol when driving on winding or
slippery roads, or in heavy or vary­
ing traffic.
• Only usa cruise control when
traffic and weather conditions al­
low you to drive at a steady speed.
• To prevent unintended opera­
tion of cruise control, turn it off
when it is not being used.
• It is dangerous to use the Re­
sume feature when the previously
set speed is too fast for existing
traffic conditions.
The system is operated with switch A and
button B located on the tum signal lever. Switc
hing the system on
Slide switch A to ON.
Se tting speed
When the vehicle reaches the speed to be
maintained, push button B (SET). Now you
can take your foot off the gas pedal.
You can increase the speed by using the ac­
celerator pedal. When the pedal is released,
the system continues to control the vehicle
at the speed previously set.
However, this will not occur if the vehicle
speed exceeds the speed that was set by
more the 6 miles per hour (10 km/hl for lon­
ger than 5 minutes. The speed will then
have to be set again.

�W ARNING
• For clear visibility and safe driv­
ing, it is extremely important that
you follow the operating instruc­
tions on the proper use and func­
tion of the ventilation/heating, de­
fogg ing{defr osting and air condi­
tioning system in this manual. If in
doubt, consult your authorized
Audi Dealer.
• Good visibility comas with
clean windows free of fog, con­
densation and frost.
• Maximum heating output and
fast defro sting will occur only af­
ter the engine has reached operat­
ing temperature. Wait until you
have good visibility before moving
your vehicle.
16 2 The
air conditioner is fully auto­
matic, and is designed to maintain a com­
fortable and uniform climate inside the ve­
hicle .
The temperature of the air supplied to the in­
terior, the fan speed, air distribution and vol­
ume of air delivery are regulated automati­
cally.
This automatic climate control program can
also be adjusted manually by the driver and
the front passenger.
The illustration on the next page shows the
controls for the driver and front passenger
in the center console. The left display indi­
cates the temperature selected for the driv­
er's side and the right display the tempera­
ture selected for the front passenger's side.
The temperature is selected by pressing the
"+" or "-" buttons beneath the respective
displays. Recommended
standard setting for
all-year operation:
After switching on the ignition
• Select a temperature of
75 oF (23°C) and
• Press AUTO button.
With this setting, you attain maximum com­
fort in the least amount of time.
You only need to change this setting to
meet your personal needs.

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.

The
first 1,000 miles (1 500 km)­
and afterwards
Break-in period
During the first few hours of driving, the en­
gine's internal friction is higher than later
when all the moving parts have been broken
in. How well this break-in process is done
depends to a considerable extent on the
way the vehicle is driven during the first
1, 000 miles (1 500 kilometres").
For the first 600 miles
(1 000 kilometres):
As a rule of thumb:
• Do not use full throttle.
• Do not drive faster than 3/4 of top
speed shown on the speedometer.
• Avoid high engine speeds.
• If possible, avoid towing a trailer. �
WARNING
• New tires tend to be slippery
and must also be "broken-ln." Be
sure to remember this during the
first 300 miles (500 kilometres).
Brake gently. Avoid following
closely behind other vehicles or
other situations that might require
sudden, hard braking.
• New brake pads don't have the
best stopp ing power and must be
.. brok en-in" during the initial 100
to 150 miles (150 to 200 kilo­
metres) of normal city driving. You
can compensate for this by press­
ing the brake pedal more firmly.
This also applies later when new
pads are installed.
From 600 to 1,000 miles
(1 000 to 1 500 kilometres):
Speeds can gradually be increased to maxi­
mum permissible road or engine speed. VE
HICL E OPER ATION
During and after break-in
period
• Do not rev the engine up to high speeds
when it is cold. This applies whether the
transmission is in N (Neutral) or in gear. dib Do not drive with unnece ssarily C!1'5 high engine speeds -upshifting
early saves fuel, reduces noise and
protects the environmeht -see also
page 195.
After the break-in period
Do not exceed maximum engine
speed under any circumstances. Up­
shift into the next higher gear before reach­
ing the red area at the end of the tachome­
ter scale -see page 117.
Excessive engine speeds are automatically
reduced.

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.

------------------------VEHICLE
OPERATION
Operate your vehicle economically and
• Do not drive if you are tired.
Make frequent rest stops, at least after ev­
ery two hours of driving.
• Always adapt vehicle speed to
traffic, weather and road condi­
tions.
Remember that especially on smooth, slip­
pery roads, vehicle handling and braking de­
pend a great deal on tire adhesion. On wet
roads, the front wheels can hydroplane es­
pecially at higher speeds. If this happens,
you will then, no longer be able to steer or
brake properly.
• Always observe the posted speed
limits and use common sense. Your
good judgment can mean the differ­
ence between arriving safely at your
destination and having an accident.
Additional information regarding safety can
be found in the individual chapters of this
manual. minimize
pollution
Va rious factors influence fuel consumption:
engine wear, brakes and tires, environmen­
tal impact.
This chapter addresses some of these
points.
Yo ur personal sty!e of driving
wi II determine the economy of your vehicle,
as well as exhaust and noise levels.
«i? Do not let your vehicle stand and
, warm
up.
When the engine is idling, it takes a very
long time to warm up. Moreover, during
warm-up, both engine wear and exhaust
gas emissions are very high. Therefore, be
ready to drive off immediately after starting
the engine and avoid high engine speeds.
«i? Avoid full throttle.
Accelerating gently reduces fuel consump ­
tion, engine wear, and does not disturb the
environment. <£'
Avoid driving at high speed.
Fuel consumption, exhaust emissions and
engine noise increase disproportionately at
high speeds. If you drive at approximately
three quarters of top speed, fuel consump­
tion will be reduced by one half. Never drive
faster than the posted speed limit and
weather conditions permitting.
r.:Cib Drive as smoothly as possible
W5 and keep a lookout ahead.
Unn ecessary accelerating and braking in­
crease fuel consumption and disturb the en­
vironment.
r.:Cib Switch off your engine if you are
W5 caught in a traffic jam. This
saves fuel and reduces emissions.
195

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;
197

VE
HICL E OPER ATION ------------------------
• Tu rning off the ignition while the
vehicle is movin g-sea page 115 -or
• Other unusual operating condi­
tions.
Do not continue to operate your ve­
hicle under these conditions, as
otherwise fuel can reach the catalyt­
ic converter. This could result in
overheating of the converter, requir­
ing its replacement.
To assure eHiciant operation of the
Emission Control System:
• Have your vehicle maintained
properly and in accordance with the
service recommendations in your
Maintenance booklet.
Lack of proper maintenance as well
as improper usa of the vehicle will
impair the function of the emission
control system and could lead to
damage.
19 8 Cl
Do not alter or remove any com­
ponent of the Emission Control Sys­
ta.m unless approved by the
manufacturer.
• Do not alter or remove any device,
such as heat shields, switches, igni­
tion wires, valves, which are de­
signed to protect your vehicle 's
Emission Control System and other
important vehicle components.
Nota
Do not leave engine idling unat­
tended after starting. If warning
lights should come on to indicate
improper operation, they would go
unheeded. Extended idling also pro­
duces heat, which could result in
overheat ing or other damage to the
vehicle or other property. �W
ARNING
• Parking
Do not park or operate the vehicle
in areas where the hot exhaust sys­
tem may coma in contact with dry
grass, brush, fuel spill or other ma­
terial which can causa a fire.
• Undercoating
Do not apply additional undercoat­
ing or rustproofing on or near the
exhaust manifold, exhaust pipes,
cata lytic converter or heat shields.
During driving, the substance
used for undercoating could over­
heat and causa a fire.
