Electronic speed limiter -
Your veh
icle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h). Thi s 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 limit­
er. The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating. For more information
c> page 256.
If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIU
¢'4 will illuminate. If this
occurs, contact the nearest authorized Aud i
dealer for assistance .

_& WARNING
-Automatic headlights are only intended
to assist the driver . They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch on the headlights
io
under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
the headlights so that you can see ahead
and so that others can see your car from
the back.
- Please observe legal regulations when
using the lighting systems described.
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
(D Tips
- The light sensor* for automatic dynamic
headlight range control* is located in the
rear view mirror mount. You should
therefore not apply any stickers to the
windshield in this area in order to pre­
vent malfunctions or failures.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display ~
page 22.
- You will hear a warning tone if you open
the driver door when the exterior lights
are switched on.
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after
switching them on. This does not affect
the service life of the lighting. Clear vision 4
