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! •

Light sensors located in the inside mirror housing and stem
constantly check the light conditions surrounding the vehicle. If
am bie nt brightness falls below a facto ry set value (e.g. wh en driv ing
into a tunnel), the head -and tai llights inc luding the license p late
ill um inat ion are automatica lly t urn ed on. When ambient br ightness
increases again, the external lights are turned off again~&.

• With the light switch at the O or ;:oo: position , only your front fog
lights remain turned on when it turns dark outside . Even though
your instruments appear well lit, the road ahead of you is not. The
light pattern provided by fog lights alone is not suffic ient for safe
driving in poor light or darknes s. Therefore:
• Always be aware of changes in outside light conditions while
you are driving. Respond in time to fading daylight by turning the

Turn signals -¢ ¢ and high beam ~D lever
The lever on the left side of the steering column is used to
operate the turn signals and the high beam as well as the
headlight flasher.
Fig. 69 Turn signa l and
high beam leve r
The turn signal and high beam lever has the following func ­
tions:
Turn signals ¢ Q
- Lift the lever up all the way ~ fig. 69, to use the right turn
signals, or push the lever down all the way to use the left
turn signals .
Auto-blink
-Move the lever (up or down) just to the point of resis ­
tance to use the turn signals for as long as you need
them, for example when changing lanes. - Briefly
move the lever up or down just to the point of
resistance and then release it to flash the turn signals
three times in succession. This feature allows to indicate
lane changes clearly and with minimum effort when
driving on highways.
High beam [D
- Push the lever forward to switch on the high beam.
- Pull the lever back towards you to switch off the high
beam.
Headlight flasher [D

• The turn signals only work with the ignition switched on . The
indicator lights ¢ or¢ in the instrument cluster => page 16 also
blink .
• After you have turned a corner, the turn signal switches off auto ­
matically.
• The high beam works only when the head lights are on . The indi­
cator light ~D in the instrument cluster i lluminates when the high
beams are on.
• The headlight flasher works only as long as you hold the lever -
even if there are no lights switched on. The ind icator light ~D in the
instrument cluster illuminates when you use the headlight flasher .
