212Driving and operatingSystem performance on hills 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. Full speed range
adaptive control is deactivated
automatically, as the vehicle is
stopping uphill on an incline greater than 10%. In this condition, be
prepared to take control of the
vehicle.
Note that applying the brake
deactivates the system.
Radar unitThe radar unit is mounted behind the
radiator grille behind or below the
brand emblem.9 Warning
The radar unit was aligned
carefully during manufacture.
Therefore, in the event of a front-
end impact, 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 adjust the radar unit
position.
Settings
A vehicle message and chime
reminds the driver to drive off when
the adaptive cruise control holds the
vehicle at standstill. This function
named Go Notifier can be activated
and deactivated in the vehicle
personalisation menu in the Info- Display.
Vehicle personalisation 3 123.
Fault
If the adaptive cruise control does not
work due to temporary conditions
(e.g. blockage by ice, overheated
brakes or low speed manoeuvres) or
if there is a permanent system error,
a message is displayed in the Driver
Information Centre.
Vehicle messages 3 122.
Intelligent adaptive cruise control
This feature is an enhancement to
adaptive cruise control. It updates the
set speed to a new detected speed
limit automatically, if the driver has
forgotten to adapt the set speed. The preferred usage of this function is
outside cities or villages. It uses
information provided by the traffic
sign assistant 3 238.
Notice
Perform updates of your
navigational maps regularly and
make sure that the correct SD-card
is inserted in the navigation map
card port.
214Driving and operatingA new speed limit from the navigationmay be taken over automatically after
a certain distance since the last
detected traffic sign or when entering
a new road segment, e.g. road exits
or round-abouts.
Forward collision alert
The forward collision alert is part of
the forward collision system 3 123. It
can help to avoid or reduce the harm
caused by front-end crashes.
A vehicle ahead is indicated by the
control indicator A.
Additionally, the status of the forward
collision alert is indicated on the
Driver Assistance page in the Driver
Information Center 3 111.
If the vehicle is equipped with
conventional cruise control, the
forward collision alert uses the front
camera in the windscreen to detect a
vehicle directly ahead, in your path.
If the vehicle is equipped with
adaptive cruise control, the forward
collision alert uses the radar sensor
and front camera to detect a vehicle
directly ahead, in your path.A precondition is that forward collision
alert in the vehicle personalisation
menu is not deactivated 3 123.
Activation
Forward collision alert with front
camera detects vehicles to distances
of approximately 60 metres and
operates automatically at all speeds
above walking speed.
Forward collision alert with radar
sensor detects vehicles to distances
of approximately 150 metres and
operates automatically at all speeds
above walking speed.
Alerting the driver
The vehicle ahead control indicator
A illuminates green in the instrument
cluster when the system has detected
a vehicle in the driving path. On
vehicles with head-up display, A is
projected on the windscreen.
The control indicator A changes to
amber when the distance to a
preceding moving vehicle gets too
small.Caution
The colour lighting of this control
indicator does not correspond to
local traffic laws on following
distance. The driver bears full
responsibility for maintaining safe
following distance according to
applicable traffic rules, weather
and road conditions etc. at all
times.
When the time to a potential collision
with a vehicle in front gets too small
and a collision is imminent, the
collision alert symbol pops-up in the
Driver Information Centre and the
driver gets notified by a flashing red
LED stripe or the pop-up symbol in
the head-up display which is
projected on the windscreen in the
driver's field of view.
238Driving and operatingActivation or deactivation of the rear
cross traffic alert can be set in the
vehicle personalisation menu in the
Info-Display.

when:
● Ice, snow, mud, stickers, magnets, metal plates, or
anything else covers the sensors.
● Driving in heavy rainstorms.
● The vehicle had an accident or if the area surrounding the
detection sensor is damaged or
not properly repaired.
● There are extreme temperature changes.
● The vehicle is towing a trailerIn 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. Seek the assistance of a
workshop.
