Switching on the windscreen wipers
Fig. 48 Windscreen wiper lever
Move the windscreen wiper lever to the appropriÂ
ate position:
@- Wipers off
CD- Intermittent wipe. Move switch @ to the left
or to the right to increase or reduce the wiper deÂ
lay interval. If your vehicle is equipped with the
rain sensor*, the windscreen wipers will be actiÂ
vated automatically in the rain as long as the veÂ
hicle has been moving faster than approx. 4 km/
ha t least once. The higher the sensitivity level for
the rain sensor* is (i.e. the further to the right
the position of switch @ is), the sooner the windÂ
screen wipers react to moisture on the windÂ
screen. You can deactivate the rain sensor mode*
on the infotainment system (this will activate the
intermittent wipe mode). Select the following on
the infotainment system: !MENU! button> Car >
left control button > Driver assist> Rain sensor >
off.
@- Slow wipe
@ -Fast wipe
@ -Single wipe. If you hold the lever in this posiÂ
tion, the wipers will switch from slow continuous
wiping to fast continuous wiping after a while.
® -Wash/wipe. The screen is given an extra wipe
a few seconds later to remove any dribbles of waÂ
ter (if the vehicle is moving and the temperature
is above approx. 4 °C). You can deactivate this
function by moving the lever to position @again
within 10 seconds after the extra wipe. The ex-
so tra-wipe
function is activated again the next time
you switch on the ignition.
Headlight washers*. The headlight washer sysÂ
tem* only operates when the lights are switched
on. The headlights are automatically washed the
first time and every fifth time you move the lever
to position ®·
A WARNING
- The rain sensor* is only intended to assist
the driver. The driver is still obliged to manÂ
ually operate the windscreen wipers as reÂ
quired depending on visibility.
- Do not use water-repellent coatings on the
windscreen. In bad visibility conditions such
as light rain, low sun or when driving at
night these coatings can cause increased
dazzle, which is a serious safety hazard.
Such coatings can also cause the wiper
blades to judder.
- Poor visibility can cause accidents. Always
ensure that the wiper blades are in good
condition ¢ page 51, Changing the windÂ
screen wiper blades.
CD CAUTION
- In icy conditions, check that the wiper
blades are not frozen to the windscreen. If
the wiper blades are frozen to the windÂ
screen when you switch on the windscreen
wipers, this could damage the wiper blades.
- Make sure you switch off the windscreen
wiper system (lever in position 0) before you
use an automatic car wash. This will avoid
inadvertent triggering of the wipers and
possible damage to the wiper system.
i Note
- The windscreen wipers are deactivated
when the ignition is switched off. You can
activate the windscreen wipers after switchÂ
ing the ignition on again by moving the
windscreen wiper lever to any position.
- Worn or dirty wiper blades can cause smearÂ
ing on the glass. This can also impair the efÂ
fectiveness of the rain sensor*. Please check
the wiper blades regularly. ______ �

(ASR) only if your driving ability and the trafÂ
fic conditions allow you to do so safely -danÂ
ger of skidding!
- The stabilising function is restricted when
sport mode is switched on. The driven
wheels may start to spin, causing the vehiÂ
cle to lose grip, in particular on slippery or
wet roads.
- When the ESC/traction control system
(ASR) is switched off, the vehicle will not be
stabilised.
@ Note
- The ESC/traction control system (ASR) canÂ
not be switched off and the sport mode canÂ
not be switched on when the cruise control
system* is on.
- In the event of a malfunction in the rear
spoiler system or the Audi magnetic ride, it
may not be possible to switch off the ESC/
ASR or switch on the sport mode.
Brakes
New brake pads
New brake pads do not give full braking effect for
the first 400 km, they must first be "bedded in".
However, you can compensate for the slightly reÂ
duced braking effect by applying more pressure
on the brake pedal. Avoid placing a heavy load on
the brakes during the running-in period.
Wear
The rate of wear on the brake pads depends a
great deal on how you drive and the conditions in
which the vehicle is operated. Negative factors
are, for instance, city traffic, frequent short trips
or hard driving with abrupt starts and stops.
Noises
Brake noise may develop in certain situations, deÂ
pending on the speed, braking force and ambient
conditions (such as temperature and relative huÂ
midity). Intelligent

Effect of moisture and salt
In certain conditions, such as in heavy rain, early
morning dew, or after washing the car or driving
through water, the full braking effect can be deÂ
layed by moisture (or in winter by ice) on the
discs and brake pads. The brakes should be
"dried" by pressing the pedal to restore full brakÂ
ing effect.
When you are driving at higher speeds with the
windscreen wipers on, the brake pads are very
briefly brought into contact with the brake discs.
This automatic process which goes unnoticed by
the driver is carried out at regular intervals and is
intended to improve braking response in wet conÂ
ditions.
The effectiveness of the brakes can also be temÂ
porarily reduced if the car is driven for some disÂ
tance without using the brakes when there is a
lot of salt on the road in winter. The layer of salt
that accumulates on the discs and pads can be
removed with a few cautious brake applications.
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 used infrequently, or if you only drive
low mileages without using the brakes very
much.
If the brakes are not used frequently, or if corroÂ
sion 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 ¢ A.
Faults in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately to the
nearest qualified workshop and have the fault
rectified. On the way to the dealer, be prepared
to use more pressure on the brake pedal and alÂ
low for longer stopping distances.
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.
