-----------------------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.

VEHICLE OPERA
TION-----------------------
Trailer towing
Yo ur Audi was designed primarily for pas­
senger transportat ion. The additional load
will affect durability, economy and perfor­
mance.
Tra iler towing not only places more stress
on the vehicle, it also calls for more con­
centration from the driver.
For this reasons, always follow the opera­
ting and driving instructions given and use
common sense.
208 Te
chnical requirements
Tr ailer hitch
Use a weight-carrying hitch conforming to
the gross trailer weight. The hitch must be
suitable for your vehicle and trailer and
securely bolted to appropriate place on the
vehicle's chassis. Use only a trailer hitch
with removable ball mount. Always check
with the trailer hitch manufacturer to make
sure that you are using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way
that it does not interfere with the impact-ab­
sorbing bumper system. No modifications
should be made to the vehicle exhaust and
brake systems. From time to time, check
that all hitch mounting bolts remain secure­
ly fastened. When
you are not towing a trailer, remove
the trailer hitch ball mount. This prevents
the hitch from causing damage should your
vehicle be struck from behind.
�W ARNING
When you are no longer towing a
trailer, remove the entire trailer
hitch. When doing so, seal all bolt
holes to prevent water and deadly
exhaust fumes from entering the
vehicle.
Engine cooling system
To wing a tr ailer make the engine work hard­
er. It is important that the engine cooling
system be up to the job. Make sure that the
cooling system has enough fluid.

VEHI
CLE CARE
J'4 WARN ING continued
• If you must work underneath
the vehicle with the wheels on the
ground, always make sure the ve­
hicle is on level ground. that the
wheels are always securely
blocked and that the engine can­
not be started. Always remove the
ignition key before anyone gets
under the vehicle.
Always make sure the transmis­
sion selector lever (automatic
transmission) is in "P" (Park posi­
tion) and the hand brake is firmly
applied.
• Always be extremely careful
when working on the vehicle. Al­ways follow commonly accepted safety practices and general com­
mon sense. Never risk personal in­
jury.

Changing the engine settings
will adversely aHect emission
levels. This Is detrimental to the en­
vi ronment and increases fuel con­
sumption.
Always observe environmental reg­
ulations when disposing of old en­
gine oil. used brake fluid, dirty en­
gine coolant, spent batteries or
worn out tires.

Engine
hood
To unlock the engine hood, pull the re­
lease lever on the left under the dashboard.
The hood pops up slightly under spring pres­
sure.
Note
Before opening the engine hood,
make sure that the windshield wip­
ers are folded flat against the wind­
shield. Otherwise, they could dam­
age the paint on the hood. To
open, pull the release lever in the direc­
tion indicated by the arrow. This will release
the hook under the hood.
Open the hood all the way. It will be held up
by gas pressure in the strut. VEH
ICLE CARE
To close
Pull the hood down until the pressure from
the strut is reduced. Then Jet the hood fall
and latch in place -you do not need to
press the hood down again.
m WARNING
• A hood that is not 'completely
latched could fly up and block
your view while driving. When you
close the engine hood, check it to
make sure the safety catch has
properly engaged. The hood
should be flush with the surround­
ing vehicle body parts.
• If you ever notice while driving
that the hood is not secured prop­
erly, stop at once and close it.

Adding engine oil
A Always heed all WA RNINGS
r!!J on page 232.
• Turn off the engine.
• Unscrew the oil cap from the cylinder
head cover.
• Add oil by a half quart (half liter) at a time.
• Check the oil level with the dipstick.
:236 The
oil level must never be above the
"a .. range.
Otherwise oil could be drawn into the crank­
case breather and get into the atmosphere
through the exhaust system. The oil
would bum then In the catalytic con­
verter and cause damage.
� WARNING
Spilled oil is a fire hazard. The oil
filler cap must be secure to avoid
an oil spill.
• Carefully screw the oil cap back on and in­
sert the oil dipstick all the way. Otherwise
oil could leak out when the engine is run­
ning. Changing
the engine oil
The engine oil must be changed according
to the intervals specified in your Mainte­
nance booklet.
This is very important because the lubricat­
ing properties of oil diminish gradually dur­
ing normal vehicle use.
Under some circumstances the engine oil
should be changed more frequently.
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or under predominantly stop-and-go
traffic conditions, or have your vehicle
where temperatures remain below freezing
for exte nded periods.
Detergent additives in the oil will make
fresh oil look dark after the engine has been
running for a short time. This is normal and
is not a reason to change the oil more often
than recommended.

CARE
Te mperature
The temperature grades are A (the highest),
8, and C, repres enting the tire's resistance to
the generation of heat and its ability to dissi­
pate heat when tested under contro lled con­
ditions on a specified indoor laboratory test
wheel. Sustained high temJ)erature can
cause the material of the tire to degenerate
and reduce tire life, and excessive tempera­
ture can lead to sudden tire failure. The
grade C corres ponds to a level of perfor­
mance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Sta ndard No. 1 09. Grades Band A represent
higher levels of performance on the laborato­
ry test wheel than the minimum required by
law.
�W ARNIN G
The temperature grade for this tire
is est ablished for a tire that is
properly inflated and not over­
loaded. Excessive speed, under­
inflation, or excessive loading, ei­
ther separately or in combination,
can causa heat buildup and pos­
sible tire failure. Wheel
replacement
If you wish to equip your vehicle with tires
or wheels other than those installed at the
factory, please note the following:
• For technical reasons it is not al­
ways possible to use wheels from
other vehicles -under certain condi­
tions not even wheels from the same
vehicle model.
• Wheel rims and wheel bolts are
matched to fit your Audi. When
installing different wheels (for ax­
ample, wheels with winter tires), the
correct wheel bolts with the proper
length and conical shape of the bolt
head must be used. The secure fit of
the wheels and the proper function­
ing of the brake system and safety
are dependent upon this.
• Wheel rims and wheal bolts are
matched to fit your Audi. •
Before you plan on exchanging
steel wheels, light alloy wheals, or
winter tires already mounted on
wheel rims, consult your authorized
Audi Dealer. They have the technical
information necessary to advise you
which wheal rims and wheel bolts
are compatible with the original fac­
tory installations.
1ft WARNING
• Incorrect tire/wheel parts may
cause an accident and personal in­
jury. Such parts will adversely af­
fect the safe operation of your ve­
hicle. Always use tires, wheel rims
and wheel bolts that meat specifi­
cations of the original factory­
installed equipment.
• If wheel trim discs or a front
spoiler are Installed, make sura the
airflow for cooling the brakes is
not obstructed.
