Fault in Adaptive forward
lighting system When the system detects a failure in
the Adaptive forward lighting system,
the system moves to a preset position to avoid dazzling of oncoming traffic.
If this is not possible, the affected
headlight will be automatically
switched off. In any case, one
headlight will stay on. A warning is
displayed in the Driver Information Centre.
Hazard warning flashers

If the lever is moved past the
resistance point, the turn signal is
switched on constantly. When the
steering wheel moves back, the turn
signal is automatically deactivated.
For three flashes, e.g. when changing lanes, press the lever until resistance
is felt and then release.
When a trailer is connected, turn
signal flashes six times when
pressing the lever until resistance is
felt and then releasing.
Move the lever to the resistance point
and hold for longer indication.
Switch the turn signal off manually by moving the lever to its original
position.

Control of the vehicleNever coast with engine not
running (except during Autostop)
Many systems will not function in this
situation ( e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 162.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by
an idle boost which may be audible.
On vehicles with Uplevel-Display or
Uplevel-Combi-Display, a message
appears in the Driver Information
Centre.Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Steering If power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.
Control indicator c 3 113.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may occur to the power steering
system and there may be loss of
power steering assist.
174Driving and operating
Fault9Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Manual parking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull the lever up slightly, press the release
button and fully lower the lever.
To reduce the operating forces of the
parking brake, depress the foot brake
at the same time.
Control indicator R 3 112.
Electric parking brake
Applying when vehicle is stationary
Pull switch m for approx.
one second; the electric parking
brake is applied automatically with an adequate force. For maximum force,
e.g. parking with trailer or on inclines:
pull switch m twice.
The electric parking brake is applied
when control indicator m illuminates
3 112.
The electric parking brake can always
be activated, even if the ignition is off.
188Driving and operating
Hill and trailer considerations
System performance on hills and
when towing a trailer depends on
vehicle speed, vehicle load, traffic
conditions and the road gradient. It
may not detect a vehicle in your path
while driving on hills. On steep hills,
you may have to use the accelerator
pedal to maintain your vehicle speed.
When going downhill, especially
when towing a trailer, you may have
to brake to maintain or reduce your
speed.
Note that applying the brake
deactivates the system. It is not
recommended to use adaptive cruise
control on steep hills especially when towing a trailer.
Radar unit
The radar unit is mounted behind the
radiator grille below the brand
emblem.
9 Warning
The radar unit was aligned
carefully during manufacture.
Therefore, after a frontal accident, do not use the system. The front
bumper may appear to be intact,
however the sensor behind can be
out of position and react
incorrectly. After an accident,
consult a workshop to verify and
correct the adaptive cruise control
sensor position.
Settings
Settings can be changed in the Auto
collision preparation menu in the
vehicle personalisation 3 130.
Fault
If the adaptive cruise control does not
work due to temporary conditions
(e.g. blockage by ice) or if there is a
permanent system error, then a
message is displayed in the Driver
Information Centre.
202Driving and operating
Side blind spot alert is active from
speeds of 10 km/h up to 140 km/h.
Driving faster than 140 km/h
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both exterior mirror displays will briefly
come on to indicate that the system is operating.
The system can be activated or
deactivated in the menu Settings in
the Info-Display, vehicle
personalisation 3 130.
Deactivation is indicated by a
message in the Driver Information
Centre (DIC).
Detection zones
The system sensor covers a zone of
approx. 3 metres on both sides of the
vehicle. This zone starts at each
exterior mirror and extends rearwards by approx. 3 metres. The height of the zone is approx. between 0.5 metres
and 2 metres off the ground.
The system is deactivated if the
vehicle is towing a trailer.
Side blind spot alert is designed to
ignore stationary objects such as
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Fault
Occasional missed alerts can occur
under normal circumstances and will
increase in wet conditions.Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice, slush, or in heavy
rainstorms. Cleaning instructions
3 264.
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre (DIC). Seek the assistance of
a workshop.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle.
The view of the camera is displayed
in the Colour-Info-Display.9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
advanced parking assist sensors,

Speed limit signs are displayed in the
Driver Information Centre until the
next speed limit sign or end of speed
limit is detected or up to a defined sign timeout.
Combinations of more signs in the
display are possible.
An exclamation mark in a frame
indicates that there is an additional
sign detected which cannot be
recognised by the system.
The system is active up to a speed of
200 km/h depending on the lighting
conditions. At night the system is
active up to a speed of 160 km/h.
As soon as the speed becomes
slower than 55 km/h the display will
be reset and the content of the traffic
sign page will be cleared, e.g. when
entering a city zone. The next
recognized speed indication will be displayed.
