Defective light bulb warning
The defective light bulb warning tells you when a vehicle
light bulb has become defective.
If a defective bulb has been detected by the system or a light bulb
burns out, the symbol with a message appears in the display to
tell you which bulb is burnt out and where it is located. For example:
REAR LEFT TURN SIGNAL
After 5 seconds, the message disappears. If you want to recall the
message into the display, press the CHECK button.
There are three reasons why the defective bulb message would appear in the display:
• the light bulb has burnt out=> page 277.
• the fuse is "blown" => page 273, "Replacing a fuse".
• the wire connection to the light bulb is defective.
Have the bulb replaced or the connection repaired by your autho ­
rized Audi Service department.
& WARNING
• Light bulbs are pressurized and could explode while they are
being changed causing serious personal injury.
• Work with due care when handling the high-voltage section of
gas discharge (xenon) lamps*. Failing to do so could result in death
or serious injury! •
Brake light defective K: U (USA

Wiper and washer system
Windshield wiper ~
The windshield wiper lever controls both the windshield
wipers and the washer system.
Fig. 72 Wiper lever:
windshield wiper lever
positions
T he windshield wiper lever :::::> fig. 72 has the following posi­
tions:
One -touch wiping
Move the lever to position G), when you want to wipe the
windshield
briefly.
Intermittent wiping ~ l (activating rain sensor)*
Move the lever up to position 0-
- Move the interval set switch@, to change the inter vals .
Low wiper speed
-Move the lever up to position ©-
High wiper speed
- Move the lever up to position @.
Automatic wiper/washer
- Pull the lever to position© (toward the steering wheel)
and hold.
- Re lease the lever . The washer stops and the wipers keep
going for about four seconds .
Turning off the wipers
-Move the lever back to position @.
The windshield wipers and washer only work when the ignition is
turned on. If you switch off the ignition with th e windshield wiper
lever still in the interval wipe position and then come back a while
later and drive off, the rain sensor will reactivate itse lf after the
vehic le speed has exceeded 4 mph (6 km/h).
The rain sensor* is only activated with the wiper lever set to posi­
tion
G) . When it starts to rain, the rain sensor will automatically acti ­
vate the intermittent wiping mode.
To reduce the sensitivity of the sensor , move switch
@ down . To
increase the sensitivity , move the switch up. The higher you adjust
the sensi tivity, 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.
During brief stops , e.g. at a r ed light, wiper mot ion wil l automati ­
cally be reduced to the next lower speed. Wipers a lready turning at
low speed . change to intermittent wip ing.
When the igni tion is turned on, the washer 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~

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.

wipers 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 windshield wiper system switched off (lever in position
0), otherwise the windshield wiper system could get damaged in the
car wash if it should sudden ly come on .

the ignition will also deactivate the rain sensor . To reactivate the
sensor, switch off the interva l wiping function, then switch it back
on again.
• Worn or dirty windshield wiper b lades cause smearing, which
can affect the operation of the light/rain sensor *. Check the condi ­
tion of your windshield wiper b lades regular ly .

service position .
Fig . 73 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

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

Clean your wiper blades regularly with a windshield washer solution
to prevent streaking. If the blades are
very dirty, for example with
insects , carefully clean the blades with a sponge or a soft brush.

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
