Unless otherwise stated, the lights only work when the ignition is switched on.
The arrangement of the controls right-hand drive models may differ from the
layout shown in » Fig. 45 on page 64 . The symbols which mark the positions
of the controls are identical.
Keep the headlights lenses clean. The following guidelines must be ob-
served » page 172 , Headlight glasses .
WARNING■
The activation of the lights should only be undertaken in accordance with
national legal requirements.■
The driver is always responsible for the correct settings and use of the
lights.
63Lights and visibility
WARNING (Continued)■The automatic driving lamp control only operates as a support and
does not release the driver from his responsibility to check the lights and, if
necessary, to switch on the light depending on the prevailing light condi-
tions. The light sensor cannot, for example, detect rain or snow. Under
these conditions we recommend switching on the low beam or fog lights!■
Never drive with only the side lights on! The side lights are not bright
enough to light up the road sufficiently in front of you or to be seen by oth-
er oncoming traffic. Therefore always switch on the low beam when it is
dark or if visibility is poor.
Note
The headlights may mist up temporarily. When the driving lights are switched
on, the light outlet surfaces are free from mist after a short period, although
the headlight lenses may still be misted up in the peripheral areas. This mist
has no influence on the life of the lighting system.

The Bi-Xenon bulbs adapt automatically to the load and driving state of the
vehicle when the ignition is switched on and when driving. Vehicles that are
equipped with Bi-Xenon headlights do not have a manual headlight range ad-
justment control.
WARNINGAlways adjust the headlight beam to satisfy the following conditions.■The vehicle does not dazzle other road users, especially oncoming vehi-
cles.■

The windscreen wipers are on for more than 15 s.
The light turns off about 4 minutes after turning off the wipers.
CAUTION
Do not attach any stickers or similar objects in front of the light sensor on the
windscreen to avoid impairing the function or its reliability.
Adaptive headlights (AFS)
Read and observe
on page 63 first.
The AFS system makes sure the street remains lit up depending on the traffic
and weather situation.
The AFS system automatically adjusts the cone of light in front of the vehicle
to the driving speed or the use of the wiper.
The AFS system works as long as the light switch is in position
» page 66 .
The AHL system operates in the following modes.
Out of town mode
The cone of light in front of the vehicle is similar to the low beam.
City mode
The light cone in front of the vehicle is adjusted so that it illuminates this and
the adjacent sidewalks, intersections, pedestrian crossings, etc. The mode is
active at speeds of 15-50 km / h.
Motorway mode
The cone of light in front of the vehicle is adjusted so that the driver can re-
spond in time to an obstruction or other hazard in time. The mode is active at
speeds above 120 km/h.
Rain mode
The cone of light in front of the vehicle is adjusted so that the driver can re-
duce the glare from oncoming vehicles in rain.
66Using the system
The mode is active when the wipers operate continuously for longer than 2 mi-
nutes at a speed of 20 - 70 km / h. The mode is deactivated when the wind-
screen wipers are switched off for longer than 8 minutes.
Dynamic cornering lights
The cone of light in front of the vehicle is adjusted to the steering angle so
that the road in the curve is illuminated. This function is active at speeds
greater than 10 km.h and in all AFS modes.
Tourist lights (Travel mode)
This mode makes it possible to drive in countries with opposing traffic system
(driving on the left/right) without dazzling the oncoming vehicles.
When this mode is active, the above-mentioned modes and the side swivel of
the headlights is deactivated.
This mode can be enabled or disabled via the MAXI DOT display in the Travel
mode » page 47 , Settings menu option.WARNINGIf the AFS system is defective, the headlights are automatically lowered to
the emergency position, which prevents a possible dazzling of oncoming
traffic. This reduces the cone of light in front of the vehicle. Drive carefully
and visit a specialist garage as soon as possible.
Note
When the “tourist light” mode is active, the warning light flashes for 10 sec-
onds each time the ignition is switched on.
