-Prior to using a car wash, the windshield
wiper system must be switched
off (lever
in position 0). This helps to prevent unin­
tentional switching on and damage to
the windshield wiper system .
@ Tips
-The windshield wipers are switched off
when the ignition is turned off. Activate
the windshield wipers after the ignition is switched back on by moving the wind­
shield wiper lever to any position.
- Worn or dirty windshield wiper blades
cause smearing which can affect the op­
eration of the rain sensor. Check the con­
dition of your windshield wiper blades
regularly.
- The rain sensor is part of the interval
wiping system. Turning
off the ignition
will also deactivate the rain sensor. To re­
activate the sensor, switch
off the inter­
val wiping function, then switch it back
on again.
- Make sure the washer fluid reservoir in
the engine compartment is topped
off
before going on a long trip. Look up
c:;, page 272 for checking and filling the
washer container.
Rear window wiper
The wiper lever is also used to operate the
rear window wiper and the automatic wiper/
washer function.
Fig. 66 Wiper lever: activati ng th e rear window w iper
and washer
The rear window wiper and the automatic wip­
er/washer functions are activated as follows:

will wipe the window approx. every four sec­
onds.
Automatic wiper/washer function
.,. Push the wiper lever forward to the second
stop,
position (J) , and hold it there for as
long as you want the rear wiper/washer to
operate.
.,. Release the lever again . the wiper will keep
running for approx. four seconds.
Switching intermittent wiper action off
.,. Pull the lever all the way back to the original
position.
As soon as the reverse gear is engaged and
the front wipers are turned on and operating
at the same time, the rear wiper also turns on
automatically.
A WARNING
Wiper blades are crucial for safe driving!
Only in good condition are they able to
clear the windows properly to provide un­ restricted visibility. Worn or frayed wiper
blades are a safety hazard!
c:;, page 67,
Replacing windshield wiper blades
(D Note
In freezing or near freezing conditions:
- Always check that the wiper blades are
not frozen to the glass before you turn
the wiper on. Loosen a wiper blade which
is frozen in place before operating the
wiper to prevent damage to the wiper
blade or the wiper motor.
- Do not use the wiper to clear a frosted
window . Using the wipers as a conven­
ient ice scraper will destroy the wiper
blades.

140 Automatic transmission
-Never hold the vehicle on an incline with
a slipping clutch. The clutch opens auto­
matically when it becomes too hot from
the overload. An indicator lamp
[O] illu­
minates and a driver message appears
c!;> page 141 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake
firmly set¢
page 257. Otherwise, any
increase in engine speed may set the ve­
hicle in motion, even with the parking
brake applied.
(D Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator peda l while a driving gear
is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the park ing brake or press the brake
pedal to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in
N will damage the transmiss ion be­
cause it is not lubricated under those cir­
cumstances.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
H ill descent control is activated when these­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitab le for the incline. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations . It may st ill be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de ­
cline levels out or you press the accelerator pedal. When the speed
is set in the cruise control
system
c!;>page 111, hill descent control is al­
so activated.
A WARNING
--
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to apply the brakes.

Homelink
Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
lights , etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to rep lace
three different remote controls from devices
in your home with one universal remote. This
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes place on the left side of the front bumper. There is a control module attached at
this location .
A one-time programming of the sensor must be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-time pro­
gramming, check whether the system uses a rolling code
¢ page 163 .
A WARNING
-Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as required by federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Using a garage door
opener without these features increases
risk of serious injury or death.
Homelink 161
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, th is can overstrain motor and
damage its electrical components - an
overheated mo to r i s a fire hazard!
- To avoid possib le injuries or property
damage, please always make abso lutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

Hill descent control
The hill descent control is switched on in off­
road mode. When slowly descending steep
gradients on loose ground or when the axles
are articulated, h ill descent control provides
assistance by automatically applying the
brakes to keep vehicle speed constant. The ve­
h icle is also rendered easier to steer by selec­
tive distribution of braking force . Hill descent
control intervenes when:
- the accelerator pedal is not pressed,
- the vehicle is trave lling less than 12 mph
(20 km/h),
- a steep gradient is detected,
-wheel behavio r indicates loose ground or
conditions with poor adhesion (e .g. also ax le
articulation) .
H ill descent control operates both driving for ­
ward and in reverse . Active hill descent con­
trol is deactivated by pressing the accelerator
pedal until the conditions for activation al ­
ready listed are met again.
A WARNING
You should only switch offroad mode on if
your dr iving abilities and road cond itions
permit.
- The stabilization function is limited
when offroad mode is switched on. The
dr iv ing wheels could spin and the vehicle
cou ld swerve, especially on slick or slip­
pery road surfaces.

Brake system
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing conditions and driving habits
c> Li::,. . On
vehicles that are either driven most ly in stop­
and-go city traffic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dealer more often than specified in
the Warranty & Maintenance booklet . Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine . This way, you prevent un­
necessary wear on the brake system .
If you
must use your brakes, do not hold the brakes
down continuously. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
the speed, b raking force and outs ide cond i­
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for example, when
driv ing through water or very heavy rain, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the bra ke pads. A
f ew careful brake applications should dry off
the brake pads or remove any ice coatings.

228 Intellig ent technol ogy
- Never let the vehicle ro ll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Servotronic - advanced
power steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic power steering sys­
tem senses the road speed and electronically
adjusts powe r assistance to provide comforta­
b le and safe steering response exact ly match­
ed to the vehicle speed.
Power steering w ill not work if the eng ine is
off. As a result, the steering wheel w ill be hard
to turn.
The power steering fluid level is checked dur­
ing the scheduled ma intenance serv ices .
@ Note
If the re is an electronic malfunct ion, ser­
votronic
w ill still function like a conven­
tional power steer ing system, p roviding a
constant steer ing support force that is no
longer proportionate to the vehicle speed .
This is most noticeab le when turning the
steering whee l at low speeds (for examp le
when parking), -more effort will be re­
quired than usual.
- Be aware of the different than usua l
steering response and adjust your steer­ i ng force accord ingly.
- Have the prob lem checked and set right
by an Aud i dealer as soon as possible.
- When the engine is running , never hold
the steering whee l turned all the way to
the right or to the left for longer than
15
seconds . The power steer ing pump w ill
overheat the hydraulic flu id if you keep holding the steering wheel turned all the
way . This is likely to damage the power
steering system.
- If the powe r stee ring system sho uld fail
entirely, or if the engine is not running
(for example, whi le be ing towed), you
will still be able to steer the ve hicle.
However,
considerably more effort will
be required to do so .
- If the power steering system should
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immediately .
- The power steering system requ ires a
specially formulated hyd ra ulic fluid . The
powe r stee ring reservoir is the one locat­
ed farthest to the rear on the left s ide of
the engine comp artment r=;,
page 259.
T he correct fluid level in the reservoir is
important for proper functioning of the
power steering .
Driving with your
quattro
With all-wheel drive , all four wheels are driv­
en .
Gen eral information
With all-wheel drive, power is distributed to
all four wheels. This happens au toma tically
depending on your driving style and the road
condit ions at the time . See also r=;,
page 224 .
Winter tire s
When driving in the winter, yo ur vehicle with
a ll-wheel drive has an advantage, even wi th
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved dr iveability and brak­
ing : these tires must be mounted o n
all four
wheels. See also r=;, page 288, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also appl ies to veh icles
with all-wheel driver=;,
