-Prior to using a car wash, the windshield
wiper system must be switched
off (lever
i n position 0) . This helps to prevent unin ­
tentiona l switching on and damage to
the windshie ld w iper system .
@ Tips
-The windshield wipers are switched off
when the ignition is turned off. Activate
the w indshield w ipers after the ignit ion
i s switched back on by moving the wind­
sh ield wiper lever to any pos ition.
- Worn or dirty windshield wiper blades
cause smearing which can affect the op­
eration of the rain sensor . Check the con­
dit ion of yo ur windshield wipe r blades
regularly.
- The rain sensor is part of the interval
wiping system. Turning
off the ignition
will a lso deact ivate the rain sensor. To re­
activate the sensor, sw itch
off the inter­
va l w iping 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 2 73 for checking and fi lling 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:

w ill wipe the window approx. every four sec­
onds.
Automatic wiper /washer function
.,. Push the wiper lever fo rward 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 origi-
nal position .
As soon as the reverse gear is engaged and
the front w ipers are turned on and operating
at the same time, the rear w iper also turns on
automatically.
A WARNING
Wiper blades are crucial for safe driving!
Only in good condit ion are they able to
clear the w indows properly to provide un­
restricted visib ility. Worn or frayed w iper
blades are a safety hazard!
c:;, page 66,
Replacing windshield wiper blades
(D Note
In freezing or near freezing conditions:
- Always check that the w iper b lades are
not frozen to the g lass before you turn
the wiper on. Loosen a wiper blade which
is frozen in place before operat ing the
w iper to prevent damage to the wiper
blade or the wiper motor.
- Do not use the w iper to clear a frosted
w indow . Us ing the wipers as a conven­
ient ice scrape r will destroy the wiper
blades.

222 Intelligent technology
To ensure that the ASR works properly, all
four wheels must be fitted with identical
tires. Any differences in rolling rad ius of
the t ires can cause the system to reduce
engine power when this is not desired. See
also¢
page 285, New tires and replacing
tires and wheels.
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automob iles are st ill
subject to wea r, depending la rgely on operat­
ing cond itions and dr iv ing habits
Q ,& . On ve­
hicles that are eithe r driven mostly in stop­
and -go city traffic or are driven 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 shou ld 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
va ls.
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for examp le, 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 careful brake applications should dry off
the brake pads o r remove any ice coatings.
When you are driving at higher speeds with
the w indshield wipers on, the brake pads will
brief ly touch the brake discs in regular inter- vals so as
to improve reaction time when brak ­
ing on wet surfaces . You, the driver, will not
notice anything.
T he effect iveness of the brakes can be reduced
when the vehicle is driven on a sa lt-covered
road and the brakes are not used . Here too,
you should clean off accumulated sa lt coating
from brake discs and pads w ith a few careful
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 regu larly or
only for short trips w ith litt le use of the
brakes.
If the brakes are not used frequently, or if cor­
rosion 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
c> ,& .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ir cuits may have fa iled
c> ,& .
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
l evel is monitored electronically .
Brake lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spect ion
c> page 298, Changing a wheel.
A WARNING
-- You shou ld perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
