The rain sensor* is only activated with the wiper lever set to position
G). When it starts to rain, the rain sensor will automatically activate
the intermittent wiping mode .
To reduce the sensitivity of the sensor ,
move switch @down . To
increase the sensitivity, move the switch up. The highe r you adjust
the sensitivity, the faster the sensor wi ll react when it senses mois ­
ture on the windshield. The pauses between wiper turns depend not
only on the sensitivity setting, but on the vehicle speed as well.
During brief stops, e.g. at a red light, wiper motion will automati ­
cal ly be reduced to the next lower speed. Wipers already turning at
low speed. change to intermittent wiping.
When the ignition is turned on, the washer jets a re heated .
With the low beam headlights switched on, pull the wiper
lever
towards you only briefly to clean the windshield. Ho lding the wiper
lever would also engage the headlight washer system each time you
clean the windshield and would drain the washer fluid reservoir
prematurely. ..

& WARNING
• Wiper blade s are cru cial fo r safe driving ! O nly when they are in
good cond it ion are they able to clear the window s properly to
p ro vi de un comp romi sed vis ibility . Worn or damaged wiper blade s
are a safety hazard
=> page 8 7, "In stalling new w ipe r blades "!
• The rain sen sor is onl y de signed to a ssis t and support the
driver. It remain s ent irely the driver' s re spon sibility to monitor
o ut side weather condit ion s a nd to manually acti vate the wipers a s
soon a s rain or drizzle reduces vi sibility through the wind shield .
• The wind shield mu st not be treat ed w ith water -repellent mate ­
rials. They can increase glare under poor visibility conditions such
a s w etne ss, darknes s, or when the sun i s lo w on t he horizon . In
addition , they can cause the windshield wipers to chatter .
0 Note
In freezing or near freezing conditions :
• Always check that the wiper blades are not frozen to the g lass
before you turn the wipers on. Loosen a wiper b lade which is frozen
in place before operating the wipers to prevent damage to the wiper
b lade or the wipe r motor.
• Do not use the wipers to clear a frosted window . Using the
wipe rs as a convenient ice scraper wil l destroy the wiper blades .
• Before you take your vehicle to an automatic car wash , make sure
you have the wi ndshield w iper system switched off (lever in position
0), otherwise the windshield wiper system could get damaged in the
car wash if it should suddenly come on .
[ i ] Tips
• The rain sensor is part of the interva l wiping system . Turning off
the ignition will also deactivate the rain sensor. To reactivate the sensor, switch off the interva l wiping function, then switch it back
on aga in. • I
f you switch off the ignition with the windshield wiper lever sti ll
in the interva l wipe position and then come back a while late r and
drive off, the rain sensor will reactivate itself after the vehicle speed
has exceeded 4 mph (6 km/h) .
• Worn or dirty windshield wiper b lades cause smearing which
can affect the operation of the rain sensor . Check the condition of
your windshield wiper b lades regularly .
• Make sure the washer fluid reservoir in the engine co mpartment
is topped off before going on a long trip. Look up=>
page 266 for
checking and f illing the washer container .•

You should inspec t the head lights regu larly (for examp le when refu ­

To ensure the sys tem works proper ly in winter, keep the washer jets
free of snow and
remove any ice using a de -icing spray .•

Braking
General information
What affects braking efficiency?
O pera tin g co ndition s and drivi ng h abit s
The brakes on today's automobiles are still subject to wear,
depending large ly on operating conditions and dr iving 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
W arr anty & Main ­
t e nanc e bo okle t.
Fai lure to have you r brake pads inspec ted ca n
resu lt 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 continuous ly.
Pump the brakes at intervals.
Moi sture or road salt
If you are driv ing faster than 50 mph (80 km/h) and the windshie ld
wipers are on, the brake pads wi ll briefly touch the brake discs in
regu lar intervals so as to improve reaction time when braking on
wet surfaces. You, the driver, wil l not notice anything.
Under ce rta in conditions, for example, when dr iving 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 b rake pads or remove any ice coatings .
At speeds
over80 km/h and with the windshie ld wiper turned on, the
brake pads are app lied briefly to the brake discs. This occurs at
regu lar interva ls wi thout the driver not icing and provides for better
brake response time under wet conditions.
The effectiveness of the brakes can be reduced when the vehicle is driven on a sa lt-covered road and the brakes are not used. Likewise,

you clean off accumulated sa lt coating from brake discs and pads
with a few ca utious applications of the brake ~
&-
Cor rosi on
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 f or sho rt 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
firm ly a few times from a moderately high speed~
&-
Fa ults in the brake system
If you shou ld notice a sudden increase in brake pedal trave l, then
one of the two brake circuits may have failed~
&-
Lo w brak e fluid l evel
Malfunctions can occur in the brake system i f the brake fluid level is
too low . The brake fluid level is monitored electronically .
Brake lining wear statu s
Brake lining wear may be checked by visua l inspection of the condi ­
tion o f the brake pads through the open ings in the wheel. If neces­
sary, the wheel may be removed for this inspection
~ page 293,
"Whee l change".
& WARNING
• You should perform braking maneuver s for the purpo se of
cl eani ng th e br ake sy stem onl y if ro ad condition s permit . Other
road u se rs mu st not be put a t ris k -you may cau se an accident!
• Before des cending a steep gr ade , reduce sp eed and sh ift tr ans ­
mi ssion into a lower gear or lower driving po sition . Do not ride the
brake s or hold the pedal d ow n too long or t oo often . This could
cau se the brake s to get hot and dimini sh brakin g efficien cy . _.
