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.

-----------------------VEHICLE OPERATION
Driving on rough roads or rugged terrain
For off road use, your Audi allroad is
equipped with a 4-level air suspension ride­
height adjustment system, in addition to all
wheel drive.
Yo ur vehicle's ground clearance (ride height)
can be adjusted to changing terrain condi­
tions with the push of a butt on.
At the highe st level setting (maximum clear­
ing level), ground clearance is 8.2 inches
(20.8 em).
Some general tips
Navar drive on terra in that is too de­
manding for the design of your ve­
hicle or for your driving abilities.
Navar t�;�ke any unnecessary
chances!
• Before you take your vehicle off-roa d,
make certain that you know how to operate
the ride height adjustment system-see pa­
ge 153. •
Make sure that you adjust the ride height
just before you travel on any rough sections
of terra in.
• Always adjust the vehicle's speed
to the trail and terrain conditions.
• Stow any luggage or other items in the
luggage compartment and make certain
that they are properly secured so that they
do not shift.
• Never travel on any roads, trails or terrain
on which motor vehicle travel is prohibited.
r.:Cib Always protect the environ­W ment. Respect our natural su�
roundings.
• After traveling off-road, remember to re­
move any branches or other foreign objects
caught in the grille, underbody or wheels. In
particular, look for foreign objects (stones)
caught in the tire treads.
Check the vehicle for possible damage.
• Clean dirty windows, headlight and tail­
light lenses and license plates. •
Check your brakes after traveling off-road
especially after driving through water.
• If need be, clean the underbody, suspen­
sion parts, etc. (for example, in an under­
body wash).
Some driving tips
Unpaved roads and off-road
• Drive slowly on unfamiliar roads and ter­
rain, and stay alert for unexpected hazards
(for example, potholes, rocks and stumps).
• To avoid hanging up the vehicle and dam­
aging the undercarriage on extremely un­
even terrain, drive over large humps with
the hump in the center of the vehicle.
Instead, always drive over the hump with
the vehicle wheels on one side of the ve­
hicle positioned over the crown of the
hump.

Braking
General notes
• The brakes on today's automobiles are
still subject to wear, depending largely on
operating conditions and driving habits. On
vehicles which are driven mostly in stop­
an d-go city traffic or which are driven hard,
the brake pads should be checked by your
authorized Audi Dealer more often than
specified in the Maintenance booklet.
• On steep slopes, you should use the
braking effect of the engine. This way, you
prevent unnecessary wear to the brake sys­
tem. If you must use your brakes, do not
hold the brakes down continu ously. Pump
the brakes at interv als.
• Under certain conditions, for example,
when driving through water or very heavy
rain, or even after washing your vehicle, the
braking effect can be reduced due to the
wet brake pads or pads which are iced-up in
the winter. A few cautious brake applica­
tions should dry off the brake pads or re­
move ice coati ngs. The
effect iveness of the brakes can be re­
duced when the vehicle is driven on a salt­
covered road and the brakes are not used.
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications.
�W ARNING
• If you damage the front spoiler,
or if you install a different spoiler,
be sure the air flow to the front
brakes is not obstructed, other­
wise the brake system could over­
heat reducing the effectiveness of
the entire brake aystem.
• Failure of one brake circuit will
impair the braking capability re­
sulting in an increased stopping
distance.
Avo id driving the vehicle and have
it towed to the nearest authorized
Audi Dealer or qualified work­
shop. VEH
ICLE OPERATION
Brake booster
�W ARNING
• The brake booster works with
vacuum pressure which is created
only when the engine is running.
Never let the vehicle roll to a stop
with the angina shut off.
• If the brake booster is not work­
ing, for example when towing your
vehicle, or because the brake boo­
ster has somehow been damaged,
the brake pedal must be pressed
harder to make up for the lack of
booster assistance.
201

VE
HICL E OPERA TION-----------------------
'4 WARN ING continued
• Before descending a steep
grade, reduce speed and shift
transmission into a lower gear or
lower driving position. Do not ride
the brakes or hold the pedal down
too long or too often. This could
cause the brakes to get hot and di­
minish braking efficiency.
• If you damage the front spoiler,
or if you install a different spoiler,
be sure the air flow to the front
brakes is not obstructed. Other­
wise the brake system could over­
heat reducing the effective ness of
the entire brake system.
• Failure of one brake circuit will
impair the braking capability re­
sulting in an increased stopping
distance.
Avoid driving the vehicle and have
it towed to the nearest Audi Dealer
or qualified workshop.
204 Electronic differential lock
(EDL)
The EDL operates in conjunction with the
ABS. The EDL acts automatically, i.e. with­
out the driver's intervention.
With the aid of the ABS sensors, this sy­
stem monitors the speed of the driven
wheels up to about 50 mph, 80 km/h .
Within the speed range at which this sy­
stem operates, if the wheels spin (e.g. on
slippery surfaces) they are braked in a con­
trolled manner , and more of the engine's
power is directed to whiche ver wheels
achieve greater traction.
Please note:
• When driving off, always be sure to keep
road conditions in mind as you accelerate.
If a drive wheel spins because it's on a slip­
perier surface, gradually increase the pres­
sure on the accelerator pedal until the car
starts to move. •
When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the accelerator pedal.
Even with the EDL working, the drive
wheels can spin and reduce your ability to
control your car.
• To prevent the disc brake of the braked
wheel from overheating, if subjected to ex­
cessive loads the EDL cuts out temporarily.
The vehicle remains operational and be­
haves in the same way as a vehicle without
EDL
If a fault occurs in the ABS the EDL is also
not functioning. This is ind icated by the ABS
warning light-see page 125.
ftl WARNING
The increased safety afforded by
EDL does not mean that you can
take safety risks. Always adapt
your driving style to the road con­
ditions and traffic situation.

Driving
with your quattro ®
The All Wheel Drive system has no operat­
ing controls that require attention.
The engine power is distributed automati­
cally to all four wheels for optimum effi­
ciency in all situations and road conditions.
The All Wheel Drive concept is perfectly
matched to the engine power of your
Audi all road. This combination gives the ve­
hicle excep tional handling and performance
capabilities, both on normal roads and in ex­
treme conditions of ice and snow.
However, it is vital to observe the following
safety notes:
�W ARNIN G
Always adjust your driving to road
and traffic conditions. Do not let
the extra safety afforded by All
Wheel Drive tempt you into taking
extra risks.
Although the All Wheel Drive is
very effective, always remember
that braking capacity is limited by
tire traction. You should therefore
not drive at excessive speeds on
icy or slippery road surfaces. ftl
WARNING continued
On wet road surfaces, be careful
not to drive too fast because the
front wheels could begin to slide
on top of the water (hydroplaning).
If this should occur, you will have
no warning from a sudden in­
crease in engine speed as with a
front-wheel drive vehicle. Always
drive at speeds which are suitable
to the road conditions.
Replacing wheels I tires
All four wheels must always have the same
rol ling radius. Different tires on the front and
rear wheels may impair vehicle control and
will damage the All Wheel Drive because of
the constantly different wheel speeds. The
proper function of the system is not af­
fected by unevenly worn tires.
For more information, see page 255. VEH
ICLE OPER ATION
Using winter tires
When driving in the winter, your vehicle
with All Wheel Drive has an advantage,
even with regular tires.
You should promptly install wheels
equipped with winter or all-season tires to
better handling and braking characteristics.
See also "Winter tires", page 260.

VEHICLE OPER
ATION-----------------------
Driving Instructions
To obtain the best possible handling of ve­
hicle and trailer , please note the following:
• A "balanced" rig is easier to operate and
control. This means that the tow vehicle
should be loaded to the extent possible and
permissible while keeping the trailer as light
as possible under the circumstances.
Whenever possible, transfer some cargo to
the luggage compartment of the tow ve­
hicle while observing tongue load require­
ments and vehicle loading considerations.
• The higher the speed, the more difficult
it becomes for the driver to control the rig.
Do not drive at the maximum per­
missible speed. Reduce your speed even
more under unfavorable load, weather or
wind conditions - particularly when going
dow nhill.
210 Be
especially careful when passing other
vehicles.
Reduce vehicle speed immediately if the
trailer shows the slightest sign of swaying.
Do not try to stop the sway ing by accel erat­
ing.
Observe speed limits. In some areas
speeds for vehicles towing trailers are low­
er than for regular vehicles.
• Always apply brakes early.
When driving downhill, shift into lower gear
to use the engine braking effect to slow
down the vehicle. Use of the brakes alone
can cause them to overheat and fail. •
The coolant temperatura gauge
must be observed carefully. H the
needle nears the upper end of the
scale, reduce speed immediately
and/or switch off the air condi­
tioner.
If the coolant temperature warning
light in the instrument cluster starts
flashing in red, pull off the road,
stop and let the engine idle for about
2 minutes to prevent a heat build-up.

VEHICLE
CARE---------------------------------------------------
Maintenance
Yo ur vehicle has been designed to help
keep maintenance requirements to a mini­
mum.
However. a certa in amount of regular main­
tenance is still necessary to assure your ve­
hic le's safety, economy and reliabili ty.
c£> By regularly maintaining your
vehicle, you help make sure that
emission standards are maintai ned,
thus minimizing adverse effects on
the envir onment.
For detailed vehicle maintenance consult
your Maintenance booklet.
Under difficult operating condi­
tions, for example at extremely low out­
side temperatures, in very dusty regions,
when towing a trailer very frequently, etc.,
some service work should be performed
between the intervals specified.
This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
228 Important
considerations for
you and your vehicle:
The increasing use of electr onics, sophisti­
cated fuel injection and emission control
systems, and the generally increasing tech­
nical complexity of today's automobiles,
have steadily reduced the scope of mainte­
nance and repairs which can be carried out
by vehicle owners. Also, safety and en­
vironmental concerns place very strict
limi ts on the nature of repairs and adjust­
ments to engine and transmission parts
which an owner can perform . Main
tenance, adjustments and repairs usu­
ally require special tools, testing devices
and other equipment available to specially
trained workshop personnel in order to as­
sure proper performance, reliability and
safety of the vehicle and its many systems.
Impr oper maintenan ce, adjustments and
repairs can impair the operation and reliabil­
ity of your vehicle and even void your ve­
hicle warranty. Therefore, proof of servicing
in accordance with the maintenance
schedule may be a condition for upholding
a possible warranty claim made within the
warranty period.
Above all, operational safety can be ad­
versely affected, creating unnecessary
risks for you and your passengers.

Radiator
fan
The radiator fan is driven by the engine via
the V-belt. The viscous clutch regulates the
speed of the fan according to the tempera­
ture of the coolant.
An auxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operation conditions.
� WARNING
• Always use extreme caution to
prevent clothing. jewelry, or long
hair from getting caught in the en­
gine driven radiator fan, V-belt or
other moving parts.
• Never touch the auxiliary elec­
tric radiator fan. The fan can
switch on suddenly and injure you.
Always heed all WA RNINGS
on page 232. Power
steering
Yo ur vehicle is equipped with a Servotro­
nic power steering. The degree of
power assistance is regulated electronically
according to road speed.
The fluid reservoir is in the engine compart­
ment near the windshield washer container.
The correct fluid level in the reserv oir is im­
portant for the proper functioning of power
steer ing.
The power steering fluid level is checked
during the scheduled Maintenance ser­
vices.
If the electronic regulating system is not
working properly, this is most noticeable
when turning the steering wheel at low
speeds (for example when parking) -more
effort will be required than usual. The fault
should be rectified by an Audi Dealer as
soon as possible. VEH
ICLE CARE
Note
• When the engine is running, never hold
the steering wheel turned all the way to the
right or to the left for longer than 15 sec­
onds. The power steering pump will over­
heat the hydraulic fluid if you hold the steer­
ing wheel all the way turned.
This will damage the power steering
system.
Each time the steering wheel is turned all
the way to the right or left when stopped,
you will hear noises caused by the severe
stress placed on the power steering pump.
At the same time, engine idle speed drops.
• If the power steering system
should fail, or if the engine is not
running (for example, while being
towed). you will still be able to steer
the vehicle, however. more effort
will be required.
• If the power steering system should
have a leak, or is not functioning properly,
contact your authorized Audi Dealer imme­
diately.
