appear in the Driver Information
Centre.When the vehicle is being driven, the
load reduction function temporarily
deactivates certain functions, such as the air conditioning, the heated rear
screen, heated steering wheel, etc.
The deactivated functions are
reactivated automatically as soon as
conditions permit.Vehicle personalisation
The vehicle's behaviour can be
personalised by changing the settings in the Info-Display.
Depending on vehicle equipment and
country-specific regulations some of
the functions described below may
not be available.
Some functions are only displayed or
active when the engine is running.
Graphic-Info-Display
Press MENU to open the menu page.
Use four-way button to operate the
display:
116Lightingwide and symmetrical. If the speed is
below 19 mph, the headlamps are
slightly swiveled to the outside to
allow an earlier recognition of of
pedestrians and objects on each side
of the road. A special beam pattern is
designed to avoid glare for other road
users.
Corner light
When turning off, depending on the
steering angle and the turn signal light, particular LEDs are triggered
which illuminate the direction of
travel. It is activated up to a speed of
25 mph.
Adverse weather light
Controlled by wiper or rain sensor and activated at rain and snowfall. The
wide light distribution – slightly
swiveled to the outside – enables
improved orientation at the edge of
the road. The intensity of the light in
the far distance is increased in order
to recognize objects and markings on
the right road side and obstacles on
the lane despite the weather
condition. Lowering the reflection on
wet roads reduces dazzling of
oncoming traffic. Adverse weather
light is activated up to a speed to 43 mph.
Curve light
Particular LEDs, based on steering
angle and speed, are additionally
triggered to improve lighting in
curves. This function is activated at
speeds from 25 mph to 43 mph and
reacts to steering angle.
High beam assist This feature allows the high beam to
function as main driving light at night.
The camera in the windscreen
detects the lights of oncoming or
preceding vehicles. Each LED on
right or left side can be triggered or
faded out particularly according to the traffic situation. This gives the best
light distribution without dazzling
other road users. Once activated,
high beam assist remains active and
switches high beam on and off
depending on surrounding
118LightingTo reactivate the high beam assist,
flash the headlights again.
Fault in LED headlight system
When the system detects a failure in
the LED headlight system, it selects a preset position to avoid dazzling of
oncoming traffic. A warning is
displayed in the Driver Information
Centre.
Hazard warning flashers
Operated by pressing ¨.
When braking in an emergency, the
hazard warning flashers are switched
on automatically depending on the
force of deceleration. They are
switched off automatically the first
time you accelerate.
Turn and lane-change signalslever up:right turn signallever down:left turn signal
A resistance point can be felt when
moving the lever.
Constant flashing is activated when
the lever is being moved beyond the
resistance point. It is deactivated
when the steering wheel is moved in
the opposite direction or lever is
manually moved back to its neutral
position.
Activate temporary flashing by
holding the lever just before the
resistance point. Turning lights will
flash until lever is being released.
To activate three flashes, tap the
lever briefly without passing the
resistance point.
If you forget to cancel the turn and
lane-change signals for more than
twenty seconds, the volume of the
audible signal will increase if the
speed is above 40 mph.
