When the Off-road-Lights are switched on,
the active light function is deactivated and
the headlamp range adjustment is set to the
static mode. Adaptive Highbeam Assist
G
WARNING
Adaptive Highbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, vision and traffic con-
ditions.
The system may be impaired or deactivated:
R if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the area of the windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by a sticker
The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind a crash barrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually.
You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in front of your vehicle, and conse- quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. X
To activate: activate the Adaptive High-
beam Assist function using the on-board
computer (Y page 240).
X Turn the light switch to Ã.
X Press the combination switch beyond the
pressure point in the direction of arrow :
(Y page 113).
If it is dark and the light sensor activates
the dipped-beam headlamps, the _
indicator lamp in the instrument cluster
lights up.
If you are driving at speeds above
45 km/h:
the headlamp range is set automatically
depending on the distance between the
vehicle and other road users.
If you are driving at speeds above
55 km/h and no other road users are rec-
ognised: 116
Exterior lightingLights and windscreen wipers

the main-beam headlamps are switched on
automatically. The
Kindicator lamp in
the instrument cluster also lights up.
If you are driving at speeds below
45 km/h or other road users are recog-
nised or the roads are adequately lit:
the main-beam headlamps are switched off
automatically. The Kindicator lamp in
the instrument cluster goes out. The _
indicator lamp in the instrument cluster
stays on.
X To deactivate: move the combination
switch back to its normal position.
The _ indicator lamp in the instrument
cluster goes out. Headlamps misted up on the inside
The headlamps may mist up on the inside if
there is high atmospheric humidity.
X Switch on the lights and drive off.
The level of moisture diminishes, depend-
ing on the length of the journey and the
weather conditions (humidity and temper-
ature).
If the level of moisture does not diminish:
X Have the headlamps checked at a qualified
specialist workshop. Interior lighting

Coolant temperature gauge
The coolant temperature gauge is in the
instrument cluster on the left-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †.
At high outside temperatures and when driv-
ing uphill, the coolant temperature may rise
to the end of the scale. Rev counter
The red band in the rev counter indicates the
engine's overrevving range.
! Do not drive in the overrevving range.
Doing so will damage the engine.
The fuel supply is interrupted to protect the
engine when the red band is reached. Outside temperature display
The outside temperature display is in the mul-
tifunction display (Y page 229). G
WARNING
At temperatures just above freezing point, the
street may be icy, especially in wooded areas
or on bridges. If you do not adapt your driving
style to the conditions, the vehicle could skid.
For this reason, adapt your driving style and
speed to the weather conditions.
Changes in the outside temperature are dis-
played after a short delay. Displays and operation (12-button multifunction steering wheel)
