Clear vi sion 55
The w indshield wipers and washe r only work
whe n the ignition is turned on . If you switch
off the ignition with the w indshie ld w iper lev ­
er st ill in the interva l wipe position and then
come back a whi le later and drive off, the rai n
senso r will reactivate itsel f after the vehicle
speed has exceeded 4 mph (6 km/h) .
The rain sensor* is only activated with the
wiper lever set to position @. When it starts
to rain, the rain sensor will automat ically acti ­
vate the intermittent w iping mode.
To reduce the sensitivity of the sensor, move
switch ® down. To increase the sensitivity,
move t he switch up. The h igher you adjust the
sens it ivity, the faster the senso r will react
when it senses mo isture on the windsh ield .
The rain sensor w iper intervals depend on the
sensit ivity sett ing as well as vehicle speed.
D uring brief s tops, wipe r mot io n will adjust in
r elat ion to the amou nt of rain on the w ind­
shield .
Automat ic w iper/was her : To eliminate water
drople ts, t he windsh ield wiper pe rforms o ne
afterw ipe ope ra tion after severa l seconds
whi le dr iv ing . You ca n sw itch this f unct ion off
by moving the leve r to posit io n ® within
10 seconds of the afterw ipe operat io n. The af­
terwipe function is reactivated the next time
the ignitio n is switch.
When the igni tio n i s tur ned on, the washe r
jets are heated*.

as rain or drizz le re duces visibi lity
through th e windshield.
- The windshie ld must not be treated with
water-repe llent materials. They can in­
crease glare under poor visibility condi­
t ions such as wetness, darkness, or when
the sun is low on the horizon . In addi­
t ion, they can cause th e windshield wip­
ers to chatter.
(D Note
- In the case of frost, check whether the
windsh ield wiper b lades are frozen to
the windshield. Switching on the wind­
shield wipers can damage the wiper
blades!
- Do not use the wipers to clear a frosted
window . U si ng the w ipers as a conven­
i en t ice s craper will destroy the wiper
blades .
- Prior to using a car wash, the windshield
wiper system m ust be switched off (lever
i n position 0) . This helps to prevent unin­
tentiona l switching on and damage to
the windshie ld wiper system.
(D Tips
- The w indshield wipers are swi tched off
when the ignition is turned off. Activate
the windshie ld wipers after the ignition
i s sw itched back on by mov ing the w ind ­
shield wiper lever to any pos it ion.
- Worn or dirty windshie ld wiper blades
cause smearing, which can affect the op­
eration of the light/rain sensor*. Check
the condition of your windshie ld w iper
blades regularly.
- The rai n sensor is part of the interval
wiping system. Tur ning off the ignition
will a lso deact ivate the rain sensor. To re­
activate t he senso r, switch off the inter­
val w iping function, then sw itch it ba ck
on aga in.

shie ld washer solution to prevent streaking . If
the blades are very d irty, for example with in­
sects, carefu lly clean the blades w ith a sponge
or a soft b rush.
If the wiper b lades beg in to streak the wind­
shield, this could be caused by res idue left on
the w indshield by automat ic car washes .

examp le, if yo u want to p rotect the
w indshield from icing by using a cover. ..,_

As soon as the test is completed, the system
is in normal operating mode.
Switching off
E SP should normally be activated at all times
because this ensures optimum vehicle stabil i­
ty. In certa in situations, it might make sense
to a llow some slip . For example:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow cha ins
Press the
[!I button . The ESP indicator light I)
turns on and S tabil isat ion prog ram off ap­
pears in the d isp lay. ASR deact ivates com­
pletely and the stab ilizat ion effects from the
ESP system are lim ited.
S wi tc hing on
Press the [!I button again. The message S tab i·
li sa tion p rogram on
appears briefly in the dis­
play.
A WARNING
You should only sw itch the ESP off if your
driving ability and the traffic s ituation per­
m it. Please note that when ESP/ASR is de­
act ivated, the drive whee ls can sp in on icy
and slippe ry roads and the vehi cle can
break away - danger of skidding!
(j) Tips
If A udi magnetic ride* is malfunctioning,
the ESP may not switch off or it may
sw itch off automatically.
Braking
General information
What affects braking efficiency?
Operating condit ions and d riving habit s
The brakes on today's automobi les are st ill
subject to wear, depending largely on operat­
ing cond itions and dr iving habits
q .&. . On ve ­
hicles that are either driven mostly in stop­
and -go city traffic or are driven hard, the
brake pads should be checked by your author-
Int ellig ent technolog y 163
ized Audi dea ler more often than specified in
the
W arra nty & M aintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you sho uld use the b raking
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 cont inuously. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
speed, braking force and outs ide cond it ions
such as temperature and humidity.
Mo isture o r road sal t
If you are driving faster than SO mph (80 km/
h) and the windshield wipers are on, the brake
pads will briefly touch the brake discs in regu­
lar intervals so as to improve react ion time
when brak ing on wet surfaces. You, the driver,
will not not ice anything.
Under certain conditions, for example, when
driv ing through water or very heavy ra in, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few cautious brake applications should dry off
the b ra ke pads or remove any ice coatings.
The effectiveness of the brakes ca n be reduced
when the vehicle is driven on a salt-cove red
road and the brakes are not used. l ikewise,
you clean off accumulated salt coating from brake d iscs and pads w ith a few cautio us ap­
plications o f the b ra ke
¢ .&, .
Corrosion
T here may be a tendency for di rt to b uild up
o n the brake pads and corros ion to fo rm on
the d iscs if the car is not d riven regu larly or
o nly for short tr ips w ith litt le use of the
brakes.
If the brakes a re not used frequently, o r if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads and d iscs by braking
firmly a few times from a moderately high
speed ~.&. . .,.
