WARNING continued
• If the brake warning light does
not go out with the engine running
and the parking brake released, or
lights up while you ere driving, the
fluid level in the brake fluid reser­
voir is too low.
• If you believe that it Is safe to do
so, proceed immediately at low
speed to the nearest authorized
Audi Dealer or qualified workshop
and have the brake system in­
spected.
• Please be very careful and be
sure to remember that after sev­
eral brake applications, you will
need greater pressure on the brake
pedal to stop your vehicle. Conse­
quently, you must allow for in­
creased braking distances. Trying
to brake as quickly as usual could
lead to an accident.

This
light comes on when the ignition is
turned on and goes out after the engine is
started. If the light does not go out after
star ting and rewing up the engine momen­
tarily or lights up while driving, there may be
a malfunc tion in the electrical system, or the
V- belt driving the gener ator may be broken. A If the warning light comes on
V while driving, stop the vehicle
and turn oft the engine. Inspect the
belts.
If the V-belt is not torn, you can still continue
driving to the nearestAudi Dealer. However,
since the battery is no longer being charged,
switch off all unne cessary electrical equip­
ment.
If the V- belt is tom, the power steering and
the radiator fan will also not work.

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
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.

VE
HICL E OPER ATION------------------------
Functioning of Anti-Lock Brake
System (ABS)
The ABS contributes effectively to vehicle
control since it prevents the wheels from
locking when the brakes are applied. This
means that the vehicle remains steerable
and is less likely to skid.
Nota
Yo u don't have to "pump" the brake.
Just hold the brake pedal down.
However, do not expect that the ABS short­
ens braking distance under all circum­
stances. When driving on gravel or on newly
fallen snow on top of icy surfaces, braking
distance may be even longer , therefore, un­
der these circumstances, it is especially im­
portant that you drive slowly and with great
care.
202 How the
ABS system works
An automatic check is made when a speed
of about 4 mph (6 km/h) is reached.
When this happens a pumping noise can be
heard.
If an individual wheel begins to rotate too
slowly in relation to vehicle speed and tends
to lock, the ABS automatically reduces
brake pressure to prevent that wheel from
locking.
This automatic adjustment process
will cause a slight vibration of the
brake pedal and soma noises to alert
you that vehicle speed must be
adapted to existing road and traffic
conditions. Enhanced
ABS function {Offroad­
Mode)
To improve braking on loose terrain (for ex­
ample: gravel, scree, mud, slush, snow),
turn off the ESP (see page 205), which will
switch the ABS to a special mode designed
for off-road requirements.
In this mode, the ABS control system is
changed to allow a "wedge" of loose rock
or soil to form in the front of the wheels.
This improves braking performance.
The ESP indicator light in the instrument
cluster will come on when you have
switched to this special ABS mode (see
page 124).
This special ABS mode will remain active up
to about 40 mph (60 km/h). ABS operation
is not affected at speeds over 40 mph
(60 km/h).
To turn his special ABS mode off, press the
ESP button (To activate ESP, see page 152).
The ABS off-road mode will also be deacti­
vated when vou turn off the engine.

�W
ARNING
Although the ABS is very effec­
tive, always remember that brak­
ing capability is lim ited by tire
tracti on.
Always adjust your driving speed
accor ding to the road and traffic
conditions. Do not let the extra
safety afforded by the ABS tempt
you into taking extra risks. The
ABS cannot overcome the laws of
physics.
If ABS is not functioning properly, a warning
light will come on. See page 125 for addi­
tional details. Conditions
affecting
braking efficiency
Moisture or road salt
�W ARNING
• Under certain climatic and oper­
ating conditions such as passing
through water, driving in heavy
rain or after washing the vehicle,
the effectiveness of the brakes
can be reduced. In winter, ice can
accumulate on the brake pads, lin­
ings, discs and drums. Cautiously
apply brakes for a test. Brakes will
dry and ice coatings will be
cleaned off after a few cautious
brake applications. VE
HICLE OPERATION
� WARNING continued
• Driving for an extended period
of time on salt-covered roads with­
out using your brakes can also af­
fect braking efficiency. Clean off
accumulated salt coating from
brake discs and pads with a few
cautious brake applications.
Overhea ting the brakes
�W ARNIN G
• Do not "ride the brakes" by rest­
ing your foot on the pedal when
you do not intend to brake. This
may cause the brakes to overheat,
premature wear and Increased
stopping distance.
Always heed all WAR NINGS
on next page.

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.
