166Driving and operating9Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the button
Ñ have priority over any adaptive
cruise control operation.
Switching on the system
Press C, the symbol C is indicated in
the Driver Information Centre. The system is still not active.
Activation of the functionality
Setting speed by the driver
The adaptive cruise control has to be switched on manually at a speed
between 30 km/h and 180 km/h. For
vehicles with automatic transmission, the automatic selector lever must be
in position D or M.
Accelerate to the desired speed and
move the thumb wheel to SET/-. The
current speed is stored and
maintained.The speed value is indicated in the
Driver Information Centre.
The preset speed can then be
changed by moving thumb wheel to
RES/+ to increase or SET/- to
decrease the speed. Move thumb wheel repeatedly to change speed in
small steps, move and hold to change
speed in large steps.
When the adaptive cruise control is
operating, the stop-start system is
automatically deactivated.
Driving and operating169The adaptive cruise control is
deactivated automatically when:
● The brake pedal is depressed.
● The vehicle accelerates above 180 km/h or slows down below
30 km/h.
● The electric parking brake is applied.
● The Traction Control system or Electronic Stability Control is
deactivated or operating.
● The selector lever of automatic transmissions is neither in D nor
in M.
● A fault is detected in the Electronic Stability Control or theradar system.
Switching off the system Press C, the adaptive cruise control
mode is disabled and the adaptive
cruise control indication extinguishes
in the Driver Information Centre.
Pressing ß to activate the speed
limiter deactivates adaptive cruise
control.Switching off the ignition deletes the
stored set speed.
Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it again.
● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control of the vehicle.
● Do not use the adaptive cruise control during rain, snow or
heavy dirt, as the radar sensor
can be covered by a water film,
dust, ice or snow. This reduces or suppresses completely the
visibility. In case of sensor
blockage, clean the sensor
cover.
● Do not use the system when the spare wheel is in use.System limits9Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles only
at low speed.

vehicle in its near surroundings.Thus,
the vehicle can be manoeuvred
around obstacles nearby. This view is available with auto mode or in the
view selection menu.
180° view
The 180° view facilitates reversing

Fault
In the event of a fault, C appears in
the instrument panel, accompanied
by a display message and a warning
chime. Contact a dealer or a qualified
workshop to have the system
checked.
System limitations The system performance may notoperate properly when:
● Vehicle speed is below 60 km/h.
● Windscreen is not clean or affected by foreign objects, e.g.
stickers.
● Driving on winding or hilly roads.
● During nighttime driving.
● Adverse environmental conditions like heavy rain, snow,
direct sunlight or shadows.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,dirt, windscreen damage or
affected by foreign objects, e.g.
stickers.● The sun is shining directly into the camera lens.
● Close vehicles ahead.
● Driving on banked roads.
● Driving on road edges.
● Driving on roads with poor lane markings.
● Sudden lighting changes.
The system can not operate when no
lane marking is detected.
Lane keep assist
Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
observes the lane markings between
which the vehicle is driving. If the
vehicle approaches a lane marking, the steering wheel is gently turned to
position the vehicle back into the lane. The driver will then notice a turning
movement of the steering wheel. Turn steering wheel in same direction, if
system steers not sufficient. Turn
steering wheel gently into opposite
direction, if lane change is intended.When the system steers to correct the trajectory of the vehicle, a flashes
yellow in the instrument cluster.
A warning message in the Driver
Information Centre accompanied by a
warning chime alerts the driver when
immediate driver´s action is required.
Unintended lane departure is not
assumed by the system when the turn lights are operated and during
20 seconds after turn lights have
been switched off.
Note
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.
Following preconditions have to be
fullfilled:
● vehicle speed must be between 65 km/h and 180 km/h
● the driver must hold the steering wheel with both hands
● the change of trajectory is not accompanied by operation of theturn lights
● the Electronic Stability Control is activated and not in operation
194Driving and operating● winding or hilly roads
● road edges
● sudden lighting changes
● adverse environmental conditions, e.g. heavy rain or
snow
● vehicle modifications, e.g. tyres
Switch off the system if the system is
disturbed by tar marks, shadows,
road cracks, temporary or
construction lane markings, or other
road imperfections.9 Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert,
even if a lane marking is detected.
The steering of the lane keep
assist may not be sufficient to
avoid a lane departure.
The system may not detect hands-
off driving due to external
influences like road condition and
surface and weather. The driver has full responsibility to control the vehicle and is always required to
keep the hands on the steering
wheel while driving.
Using the system while towing a
trailer or on slippery roads could
cause loss of control of the vehicle
and a crash. Switch the system off.
Driver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the trajectory
variations of the vehicle compared to
the lane markings.
9 Warning
The system cannot replace the
need for vigilance on the part of
the driver. Taking a break is
recommended as soon as feeling tired or at least every two hours.
Do not take the steering wheel
when feeling tired.
Activation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 108.
The state of the system stays in
memory when the ignition is switched
off.
Driving time alert The driver gets notified by a pop-up
reminder symbol € in the Driver
Information Centre simultaneously with an acoustic alert if the driver has
not taken a break after 2 hours of
driving at a speed above 65 km/h. The
alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.
