The warning lights in the instrument cluster indicate certain functions or
faults.
Some warning lights can be accompanied by acoustic signals and messages in

out a few seconds after switching on the ignition or after starting the engine.
The warning lights are located at the following positions in the instrument

The headlight assistant (referred to as just system in the following) automati-
cally switches the main beam on/off, if necessary, adjusts the beam of the
front headlights in accordance with the existing traffic situation (other vehi-
cles) and environmental conditions (e.g. driving through a lit village).
The switching on/off of the main beam, if necessary, the adaptation of the
headlight, is controlled by a sensor » Fig. 53.
Depending on the equipment, the following system versions can exist.
Light Assist
automatically switches the main beam on/off.
Dynamic Light Assist
automatically adjusts the light cone shape of the front head-
lights in order to prevent dazzling the oncoming and preceding vehicles, while
ensuring the highest possible illumination of the road edges.
If the driving mode Eco » page 240 , Select the driving mode (Driving Mode
Selection) or travel mode » page 71 , Driving abroad is selected, the automatic
adjustment of the beam is deactivated,
Dynamic Light Assist
only switches the
main beam on/off automatically.
If the Xenon headlights are in the mode rain or fog » page 69 , then
DynamicLight Assist
is deactivated.
If there is a fault, the error message will appear in the instrument cluster dis-
play. Seek help from a specialist garage.
71Lights and visibility
WARNINGThe system is used only for support, thus the driver is not released from his
obligation to manually adjust the main or low beam according to the given
ambient conditions (e.g. in unfavourable lighting and weather conditions,
as when passing poorly lit road users, if necessary, when the visual range
of the sensor is limited by an obstacle).
CAUTION
Do not attach any stickers or similar objects in front of the sensor on the wind-
screen to avoid impairing the function of the system.
