later and drive off , the rain sensor will reactivate itse lf after the

To reduce the sens itiv ity of the sensor, move switch© down . To
increa se the sensitivity, move the switch up . The h igher you adjust
the sensitivity, the faster the sensor will react when it senses mois ­
ture on the w indshie ld. The pauses between wiper turns depend not
only on the sens itivity setting, but on the vehicle speed as well.
During brief stops, e .g . at a red light, wiper motion will automati ­
cally be reduced to the next lower speed. Wipers a lready turning at
low speed . change to intermittent wiping .
When the ignition is turned on, the washe r jets are heated. ...

& WARNING
• Wiper blades are crucial for safe driving! Only when they are in
good condition are they able to clear the windows properly to
provide uncompromising visibility. Worn or damaged wiper blades
are a safety hazard~
page 63, "Replacing front wiper blades"!
• The light/rain sensor* is only designed to assist and support
the driver. It remains entirely the driver's responsibility to monitor outside weather conditions and to manually activate the wipers as
soon as rain or drizzle reduces visibility through the windshield.
• The windshield must not be treated with water-repellent mate­
rials. They can increase glare under poor visibility conditions such
as wetness, darkness, or when the sun is low on the 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 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 wiper motor.
• Do not use the wipers to clear a frosted window . Using the
wipers as a convenient ice scraper will destroy the wiper blades.
• Before you take your vehicle to an automatic car wash, make sure
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 suddenly come on.
[ i] Tips
• The rain sensor is part of the interval wiping system. Turning off
the ignition will also deactivate the rain sensor . To reactivate the
sensor, switch off the interval wiping function, then switch it back
on again.
Controls and equip ­
ment
Clear vision
• Worn or dirty windshield wiper blades cause smearing, which
can affect the operation of the light/rain sensor*. Check the condi­
tion of your windshield wiper blades regularly.
• Applies to vehicles with light/rain sensor: When the wipers are
switched on manually and in rain conditions, the automatic head­
lights* turn on~
page 52, "Sensor activated head and tail light
control" or off during the day when the wipers are no longer oper­
ating. The automatic headlights * function is available in this case
only when the light switch is in the "AUTO" position~
page 52,
fig. 40.
• Make sure the washer fluid reservoir in the engine compartment
is topped off before going on a long trip. Look up~
page 233 for
checking and filling the washer container .
• The wipers only operate with the hood completely closed. •
Applie s to v ehi cles: with he adli gh t wash er syst em
Headlight washer system
The headlight washer system cleans the headlights.
Operate the windshield wiper/washer system=> page 60,
fig. 50 ® with the headlights turned on by holding the
lever for longer than one second.
The washer jets extend forward out of the front bumper driven by
water pressure to spray the front headlights with water .
You should inspect the headlights regularly (for example when refu ­
eling) and clean off any solid dirt or insects from the lenses.
To ensure the system works properly in winter, keep the washer jets
free of snow and remove any ice using a de -icing spray. •

Service position The wiper blades can be changed more easily in the
service position .
Fig . 51 Wiper lever
It is only possible to change wiper blades if you move the
w iper arms to the service position. On vehicles with the
Driver Information System , the wiper blades can only be
moved to the service or parked position via t he menu
display =>
page 27. In order to use the windshield wipers,
the hood must be completely closed.
Moving wiper blades to the service position
-When there is a risk of frost, make sure that the wiper
blades are not frozen to the windshield .
- Switch the ignition on .
- Switch the ignition off again and move the wiper lever
~ fig. 51 from position Oto 1 within 10 seconds . The
wiper arms now move into the field of view in the wind ­
shie ld.
Moving wiper blades to park position
-Make certain that the wiper arms are lying against the
windshield .
- Switch the ignition on and move the wiper lever~ fig . 51
from position Oto
1. The w iper arms w ill move back to the
park position.
I t is much easier to chang e wiper blad es if you mov e th e wiper arms
to the service position. You wil l also avoid paint damage to the hood
when working on the wip ers when they are in the service position .
0 Note
Never drive your vehicle when the windshield wiper arms are in the
service position and pulled away from the windshield . When you
drive faster than 4 mph (6 km/h) , the wiper arms automatica lly
return back to the park position and could cause paint damage to
the engine hood!
[ i ] Tips
• You can also turn on the service position, for example, if you
want to protect the windshield from icing by using a cover.
• The service position moves to
off automatically when you
operate the windshield wiper lever, or speed exceeds
4 mph
(6 km/hl. •

park position .
The front wiper blades measure left side 23.20 in. (590 mm ) and
right side 18 .50 in . (470 mm) in length,
Clean your wiper b lades regularly with a windshield washer solution
to prevent streaking. If the blades are
very dirty, for example with
insects, carefully clean the b lades w ith a sponge or a soft brush.
If the wiper blades begin to streak the windshield , this could be
caused by residue left on the windshield by automatic car washes .
Fill the windshield washe r container with a special solution avail ­
able at your authorized Audi dealer to
remove the residue.
Be sure to inspect the condition of your wiper blades regular ly . For
safety reasons, rep lace your wiper blades once or twice a year if
necessary. See your authorized Audi dealer for replacement blades . .,
