G). When it starts to rain, the rain sensor will automa tically activate
the intermittent wiping mode .
To reduce the sensitivity of the sensor, move switch @down . To
inc rease the sensitivity, move the switch up. The higher you adjust
the sensitivity, the faster the sensor will 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.
The rain sensor wiper interva ls depend on the sensitivity setting as
we ll as vehic le speed. During brief stops, wiper motion will adjust to
the amount of rain on the w indshield.
When the ignit ion is turned on, the washer jets are heated .
With the low beam headlights switched on, pull the wiper lever
towards you only
briefly to c lean 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.

0 Note
I n freezing or near freezing conditions :
• Always check that the wiper blades are not frozen to the glass
before yo u turn the wipers on. Loosen a wiper b lade which is frozen
in place before operating the w ipers 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 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 J 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 interval wiping function, then switch it back
on again. •
If you switch off the ignition with the windshield wiper lever sti ll
in the interva l wipe position and then come back a while later 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 opera tion of the rain sensor . Check the conditio n of
your windshield wiper blades regularly .
• Make sure the washer fluid reservoir in the engine compartment
is topped off before going on a long trip . Look
up=> page 291 for
checking and filling the washer container .•

Clean your wiper blades regularly with a windshield washer solution
to prevent streaking. If the blades are very dirty, for examp le with
insects, carefully clean the blades with 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 washer 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 regularly. For
safety reasons, replace your wiper blades once or twice a year if
necessary. See your authorized Audi dealer for replacement
blades. ~
