with low/high beam and sidelights.
Automatic light control
When the automatic light control
function is switched on and the
engine is running, the system
switches between daytime running
lights and headlights automatically
depending on the external lighting
conditions and information given by
the wiper system.
Daytime running light 3 134.
Automatic headlight activation
During poor lighting conditions
headlights are switched on.
Additionally, headlights are switched
on if the windscreen wipers have
been activated for several wipes.
LED headlights 3 134.
Tunnel detection
When a tunnel is entered, headlights
are switched on immediately.
High beam
Push lever to switch from low to high
beam.
Pull lever to deactivate high beam.
High beam assist 3 134.
High beam assist Description for version with halogen
headlights. High beam assist with
LED headlights 3 134.
This feature allows the high beam to
function as the main driving light at
night and when vehicle speed is
faster than 25 mph.
It switches automatically to low beam
when:
● A sensor detects the lights of oncoming or preceding vehicles.
● Driving in urban areas.
● The vehicle speed is slower than
12 mph.
● It is foggy or snowy.
● Front or rear fog lights are switched on.
If there are no restrictions detected, the system switches back to high
beam.
Vehicle care279All wheels must be equipped with
pressure sensors and the tyres must have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle operating permit.
Select the Tyre pressure monitoring
page under the Info Menu in the
Driver Information Centre 3 111.
System status and pressure warnings
are displayed by a message
indicating the corresponding tyre in the Driver Information Centre.
The system considers the tyre
temperature and the tyre loading
setting for the warnings.
Tyre loading setting, see below in this chapter.
Temperature dependency 3 277.
Baselevel display: If the pressure of a
tyre decreases significantly, the
respective tyre pressure value is displayed inverted.
Midlevel and uplevel display: Tyre
pressure values in normal range are
shown in green letters. If the pressure
of a tyre decreases significantly, the
respective value will turn its colour to
amber.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 108.
If
w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 317.
Ensure that vehicle loading status
matches selected tyre pressure.
Vehicle loading status, see below in
this chapter.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
continue to illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure.
Vehicle messages 3 122.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. Control indicator w
