Clear vision
Wint er p osition
To speed up de -icing of the windshie ld w ipers, they move to the
winter position when the ignition is switched off and at an outside
temperature below 39 °F (4 °C). In this position, the windshie ld
w ipers are in an area on the glass which is reached by the air vents
below the glass . It is a lso easier to remove snow and ice from the
windshield wipers in this position .
The wipers leave the winter position, when the ignition is switched on, if the wi ndshield wiper lever is ope rated or the active rain
sensor* reacts to moisture.
Rain sen sor*
The rain sensor operates only in the interval wiper position. When it
s tarts to rai n, the interval wiper m ode is ac tivated aut omatically.
If the windshield wiper lever is in the interval wipe position with the
igni tion switched off, the rain sensor is not activated unti l vehic le
speed is above 4 mph (6 km/h).
To reduce the sensitivity of the rain sensor, the switch@ must be
moved down . T o in crease the se nsitivity of the rain sens or, the
switch must be moved up .
The higher the sensi tiv ity se tting, the so oner the w indshield wipe rs
react to mo isture on the windsh ield. Increased sensitivity is
signa led by the windshie ld wipers making a single pass over the
windsh ield.
The rain sensor wiper intervals depend on the sensitivity setting as
we ll as veh icle speed . D uring b rie f stops, wiper m otio n will adjust in
relation to the amount of rain on the windshield .
& WARNING
• Wiper blades are cru cial for safe driving! Only when they are in
good condition are they able to clear the window s proper ly to
p rovide un comp romised visibil ity . Worn or damaged wiper blades
are a safety hazard =>
page 84, "In stalling new wiper blades "!
& WARNING (continued )
• The rain sensor* is only designed to assist and support the
driver . It remain s entirely the dr iver' s re spon sibility to monitor
out side weather conditions and to manually activate the wipers as
s oon a s rain or driz zle reduce s vi sibility through the wind sh ield .
0 Note
In freezing o r near freez ing conditions:
• Always check that the wiper blades are not frozen to the glass
before you turn the wipers on. Loosen a wiper blade which is frozen
in place before operating the wipers to prevent damage to the wiper
blade or the wipe r motor.
• Do not use the wipers to clear a frosted window. Using the
wipers as a convenient ice scraper wi ll destroy the wiper blades .
• Before you ta ke you r vehicle to an automatic car was h, ma ke s ure
you have the windshield wiper system switched off (lever in position
0), otherwise the windshield wiper system could get damaged in the
car wash if it should sudden ly come on .
[ i ] Tips
• The rain senso r* is part of the interva l wiping syste m. Turning o ff
the ignition will also deactivate the rain sensor. To reactivate the
s en sor, switch o ff the interval wip ing funct ion, then sw itch it bac k
on again.
• Worn or dirty winds hield wiper b lades cause smearing which
can affect the operation of the rain sensor *. Check the condition of
your windshield wiper blades regularly .
• Make sure the washer fluid reservoir in the engine compartment
is topped o ff be fore go ing on a long trip. Look up=>
page 346 for
check ing and filling the washer container. •

The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR wil l also be out of action.
& 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 ] Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identica l tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending large ly 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 shou ld 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 shou ld use the braking effect of the engine .
This way, you prevent unnecessary wear on the brake system. If you
must use your brakes, do not hold the brakes down continuously.
Pump the brakes at intervals.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
Moisture
or road salt
If you are driving faster than 3 1 mph (50 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 careful brake applications sho uld 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. Here too,
you should clean off accumulated salt coating from brake discs and
pads with a few carefu l app lications 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 litt le use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
t he discs, it is advisable to clean off the pads and discs by braking
firm ly a few times from a moderately high speed~&.
Faults in the brake system
If you shou ld notice a sudden increase in brake peda l trave l, then
one of the two brake circuits may have failed~& .
Low brake fluid le vel
Malfunctions can occur in the brake system if the brake fluid level is
too low . The brake fluid level is monitored electronically .
Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi ­
tion of the brake pads through the openings in the wheel. If neces­
sary, the wheel may be removed for this inspection
