You can assist the self-cleaning function of
the filter by driving as follows:
Drive at a speed of at least 60 km/h for about
15 minutes in 4th or 5th gear (on vehicles with
manual gearbox), or with the selector lever in po­
sition S (on vehicles with automatic gearbox).
Keep the engine speed at about 2000
rpm.
As a
result of the increase in temperature, the soot in
the filter will be burned off. The indicator lamp
will go out once the cleaning process has been
completed successfully.
If the indicator lamp does not go out, drive to a
qualified workshop without delay and have the
fault rectified.
A WARNING
It is essential that you adjust your speed to
suit the weather,
road,
terrain and traffic
con­

ditions. The recommended driving speed
must never lead to the driver disregarding the

Audi adaptive light
Applies to: vehicles with adaptive light
With the adaptive light feature, you have better
vision in the dark because the Lights are control­
led dynamically to match the vehicle speed and
road conditions, e.g. on motorways or country

roads,
at intersections or through corners. The
adaptive light is activated only when the Light
switch is set to AUTO and the all-weather Lights*
are switched off.
WARNING
- The automatic headlights are only intended
to assist the driver. The driver must always
ensure that the headlights are used when

required,
and may have to switch them on
manually when the light conditions or
visi­

bility are poor. For example, the light
sen­

sors are not able to detect fog. Therefore,
you should always switch on the dipped
headlights
|0
in these conditions and when
driving after dark.
- To avoid dazzling the traffic behind you, the
rear fog light should only be used in accord­
ance with statutory regulations.
- If the vehicle battery has been losing charge
for
a
while, the side lights or parking lights
may be switched off automatically. Always
park your car in a safe and suitably lit place
according to the applicable regulations.
49

Lights and vision
Avoid using the side lights for long periods
(several hours). If possible, switch the left
or right parking Lights on.
Observe all relevant statutory requirements
when using the lighting systems described

here.

- The light sensor for the automatic
head­

lights*
is Located in the mounting for the in­
terior mirror. Do not affix any stickers on
this section of the windscreen.
- Depending on the export market, the rear
lights on some vehicles may be switched on
together with the headlights when the
day­

time running lights* are activated. On other
vehicles, the rear lights remain off.
-In cool
or
damp weather, the inside of the
headlights, turn signals or rear lights can
sometimes mist up, due to the temperature
difference between the interior and exterior
of the car. They should clear again partially
or completely soon after you switch on the
headlights. This phenomenon has no
influ­

ence on the life expectancy of the vehicle

lights.

Main beam assist
Applies to: vehicles with main beam assist

The
main beam assist automatically switches
the main beam headlights on or off depending
on the surrounding light conditions.

users.
The main beams are activated/deactivated
automatically depending on the position of
vehicles on either side of the
road,
on the road

speed,
and on other traffic and ambient condi­

tions.
