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.

Electronic
Stability Program (ESP)
The Electronic Stability Program helps to
control the vehicle in critical maneuvers like
curves.
When the vehicle starts up and accelerates,
the wheels are prevented from spinning by
adjusting the engine power to conform to all
road conditions. This improves vehicle sta­
bil ity.
The system operates across the entire
speed range in combination with the ABS
syst em. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will also shut
down.
When you turn on the engine, the ESP will
automatically be activated and will perform
a self-test. The
system can be activated or deactivated
by press ing the button.
The warning light comes on when the sys­
tem is switch ed off. See page 124.
If you deactivate the ESP, a special ABS
mode designed mainly for all-road condi­
tions will be activated - see page 202.
It may be advantageous to turn off the sys­
tem in certain special cases when wheel
slippage is desired such as:
- when driving on difficult terrain VE
HICL E OPER ATION
- when driving in deep snow or on a loose
surface
- when trying to "rock" out the vehicle
when it has become stuck.
After this, you should switch the system
back on.
The ABS and EDS are still functioning even
if the ESP is switched off.

VEHICLE
OPER ATION----------------------
Operation
The Anti-Lock Brake System (ABS) and the
Electronic Differential Lock (EDU are inte­
grat _ed in the Electronic Stability Progr am. In
a _ddrtron to the data provided by these func­
tions, the ESP control unit requires addition­
al measurement data provided by hig h-per­
forman ?e sensors. The rotat ional speed of
the veh1cle about its vertical axis, vehicle lat­
eral acceleration, brake pressure and the
steering angle are measured.
The direction in which the driverwishes to
travel is determined with the aid of the
stee �ing angle and the vehicle speed and is
contmually compared with the actual be­
havior of the vehicle.
If the data do not match - for example when
a vehrcle is beginning to spin out of control
- the ESP applies the brakes to the appropri­
ate wheels for the given situation and, if
necessar y, changes the vehicle traction
forces so as to reduce the slipping of individ­
ual wheels (ASR anti-slip regulation).
206 The
vehicle is then stabilized by the forces
a ?tin � on the wheel during braking. If the ve­
hicle IS overstee ring (rear tends to skid out
of the turn), the brakes are mainly applied on
the wheel that is on the outside ofthe curve.
In the case of a vehicle that is und ersteering
(tendency to slide out of the curve). the
brakes are applied at the rear wheel that is
on the inside of the curve. An audible signal
�rll accompany the brake application func­
tion.
All �SP senso rs a�e monitored continuously
wh1le the vehicle IS being driven. However,
when the vehicle is driven at low speed on
ex tremely rugged terrain, it is not always
possrble to monrtor the ESP sensors contin­
uously. Thus, in rare and exceptional cases
the ESP itself can deactivate (ESP and ABS
ind icator lights will be lit continuously).
In this case. the ride level adjustment sys­
tem lowers the vehicle to the normal level
If this happens, you may need to select th�
ride level again (see page 153).
Operation of the ESP and ABS is restored
whenever you restart the engine. m
WAR NING
! he Electronic Stability Program
•• nevertheless subject to the laws
of physics. It is particularly impor­
tant to pay attention to this fact on
wet and slippery roads.
It is therefore important that you
always adapt your driving to the
condition of the road and traffic
conditions. Do not allow the in­
creased safety provided by the
Electro nic Stability Program sys­
tem to lull you into accepting addi­
tional safety risks.

Tr ailer towing tips
Yo ur vehicle handles differently when tow­
ing a trailer because of the additional weight
and weight distribution. Safety, perfor­
mance and economy will greatly depend on
how carefully you load your trailer and oper­
ate your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in an area
away from traffic until you learn the feel of
your vehicle and trailer unit.
Backing up is difficult and requir es practice.
Steering while backing up is generally oppo­
site of that when backing your vehicle with­
out a trailer.
Maintain a greater distance between your
vehicle and the one in front of you. You will
need more room to stop.
To compensate for the trailer, you will need
a larger than normal turning radius. When
passing, remember that you cannot
accelerate as fast as you normally would be­
cause of the added load. Make sure you
have enough room to pass. After passing,
allow plenty of room for your trailer before
changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
After parking, always block the wheels of
both vehicle and trailer. Do not park with a
trailer on a slope. If it cannot be avoided, do
so only after doing the following:
• Apply foot brake.
• Have someone place chocks under both
vehicle and trailer wheels.
• With chocks in place, slowly release
brakes until wheel blocks absorb the load.
• Turn wheels to curb.
o Apply parking brake.
• Place automatic transmission in "P". If
you move the selector lever of the auto­
matic transmission to "P" before applying
the parking brake and before blocking the
wheels, you may require more force later to
move the lever out of the "P" position.
When restarting after parking on a slope, re­
verse the procedure:
• Start the engine.
• Shift transmission into gear.
o Release the parking brake and slowly
move away from the wheel blocks.
• Stop and have someone retrieve the
wheel blocks.
Notes
• Do not tow a trailer during the
break-in period of your vehicle.
• If you tow a trailer, your Audi may require
more frequent maintenance due to the ex­
tra load -see also page 228.

Brake fluid
The brake fluid reservo ir is located on the
left of the plenum chamber at the back of
the engine compartm ent.
242 Checking
brake fluid level
The correct fluid level is important for the
proper functioning of the brake system. The
fluid level in the brake fluid reservoir should
always be between the "MAX" and
"MIN" markings.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is no cause for alarm.
• If the brake fluid level falls con­
siderably below the "MIN"
mark, the brake warning light will
coma on. Do not continue to operate
the vehicle. The complete brake sys­
tem should be thoroughly checked
by an authorized Audi Dealer or
another qualified workshop and the
cause corrected.
The brake warning lamp lights up to indicate
a low fluid level in the reservoir.
For more details see "Warning I Ind icator
lights," page 126.
Contact an authorized Audi Dealer
immediately. Changing
brake fluid
The brake fluid reservoir can be dif­
ficult to reach, therefore, we recom­
mend that you have the brake fluid
changed by your authorized Audi
Dealer. Your dealer has the correct
tools and know-how to do this for
you.
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may re­
sult after a period of time. The boiling point
of the brake fluid will also decrease consid­
erably.

Emergency towing with commercial tow truck
The following information is to be used by
commercial tow truck operators who know
how to operate their equipment safely.
General hints
• Never tow your Audi otherwise
this will cause damage to the engine
and transmission.
• Never wrap the safety chains or
winch cables around the brake lines.
• To prevent unnecessary damage.
your Audi must be transported with
a car carrier (flat bed truck).
To load the vehicle on to the flat bed.
use the towing loop found in the ve­
hicle tool kit and attach to the front
anchorage.
�W ARNING
A towed vehicle is not safe for pas­
sengers. Never allow anyone to
ride in a towed vehicle for any rea­
son. Front towing
anchorage
C? n the right side under the bumper, you'll
fmd a threaded hole. Screw the towing loop
into this hole.
In ord .er to access the front towing anchor­
age, f1rst remove the front grille by pulling it
off -see illustration. Screw the towing eye tightly
into the
threaded hole until it stop turning.
After us .e, unscrew the towing loop and put
1t back In the tool kit. The towing loop
must always be kept in the vehicle.
When reinstalling the front grille, first insert
the tabs into the guides provided for them.
Then push grill back into place.

Lifting
vehicle
Lifting with workshop hoist
and with floor jack
Notes
• The vehicle should never be lifted
or jacked up from underneath the
engine oil pan, the transmission
housing, the front or rear axle or the
body side members. This could lead
to serious damage.
The same lifting points as illus trated on the
next page for the hoist also apply when a
floor jack is used.
e To avoid damage to the under­
body or chassis frame, it is neces­
sary to insert a rubber pad between
the floor jack and the lift points.
• To prevent damaging the shock
absorbers when lifting the vehicle
with a jack or on a hoist, the level
selection must be in the jack mode.
See next page. �W
ARNING
• To reduce the risk of serious in­
jury and vehicle damage, lift the
vehicle only at the special work­
shop hoist and floor jack lift points
illus trated. Failure to lift the ve­
hicle at these points could cause
the vehicle to tilt or fall from a lift
if there is a change in vehicle
weight distribution and balance.
This might happen, for example,
when heavy components such as
the engine block or transmission
are removed.
• When removing such heavy
components, anchor vehicle to
hoist or add correspo nding
weights to maintain the center of
gravity. Otherwise, the vehicle
might tilt or slip oH the hoist,
causing serious damage or person­
al injur y. DO-IT-YOU
RSELF SERVICE
�� WARNING continued
• If you must lift your vehicle with
a floor jack to work underneath,
be sure the vehicle is safely sup­
ported on stands intended for this
purpose.
• Before driving over a workshop
hoist, check that the vehicle weight
does not exceed the permissible lift­
ing capacity of the hoist.
• Before driving over a workshop
hoist, ensure that there is suHicient
clearance between the hoist and
low parts of the vehicle.
