Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=>
page 15, fig. 5 is part of the On -Board Diagnostic (OBD II) system.
The warning/indicator light illuminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabilized. This indicates that the MIL is working properly.
If the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light starts flashing, the catalytic converter could be damaged .
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected. Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be
malfunctioning . For more information=>
page 25, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate =>
page 213. •
Electronic speed limiter
Your vehicle may be factory equipped with tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limiter. The elec-
Controls and equip ­
ment
Driver information system
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information =>
page 246.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Indicator Light (MIU•"" will illuminate. If this
occurs, contact the nearest authorized Audi dealer for assistance.
& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road, traffic and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires installed. •

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.

-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

The pollutant filter (particle filter) ensures that contaminants in the
outside air (such as dus t or p ollen) are greatly reduced or stopped.
The air is also filtered in recirculation mode.
T he pollutan t fil te r element must be changed accord ing to the inter ­
vals specified in the maintenance schedule so that the air condi­
tioning system's performance is not adversely affected.
If the filter's effectiveness is weakened by driv ing t he vehic le in
areas with heavi ly polluted outside air, the filter element should also
be changed in between the listed services .

[ i ] Tips
• To avo id adverse ly affecting heating and cooling performance
and to prevent condensation on the windows, the air intake in front
of the windsh ield must be free of ice, snow, and leaves.
• The air coming from the vents and circulating through the entire
