The rain sensor wiper intervals depend on the sensitivity setting as
well as vehicle speed . During brief stops, wiper motion will adjust in
re lation to the amount of rain on the windshield.
Automatic wiper/washer : To eliminate water drop lets, the wind
sh ield wiper perfor ms one afterwipe operation a fter several
seconds while driving. You can switch this function off by moving
the lever to pos it ion © within 10 seconds of the afterw ipe opera
tion. The afterwipe func tion is reactivated the next time the ignition
is sw itch.
When the ignition is turned on , the washer jets are heated *.

& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i J Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
Generat information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending largely on operating conditions and driving habits~& .
On vehicles that are either driven mostly in stop-and-go city traffic
or are driven hard, the brake pads should be checked by your autho
rized Audi dealer more often than specified in the
Warranty & Main
tenance 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 unnecessary wear on the brake system. If you
Controls and equip
ment Safety first Vehicle operation
Intelligent technology
must use your brakes, do not hold the brakes down continuously.
Pump the
brakes at intervals.
Moisture or road salt
If you are driving faster than 50 mph (80 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regular intervals so as to improve reaction time when braking on
wet surfaces. You, the driver, will not notice anything .
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 moisture (or in freezing conditions ice)
on the brake pads. A few cautious brake applications should dry off
the brake pads or remove any ice coatings .
The effectiveness of the brakes can be reduced when the vehicle is
driven on a salt-covered road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake discs and pads
with a few cautious applications of the brake~&.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed~& .
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then
one of the two brake circuits may have failed~ &.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored electronically.
