Activation of the functionalitySetting speed by the driver
The adaptive cruise control has to be
switched on manually at a speed
between 19 mph and 112 mph. 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.
Adopting speed by the speed limit
recognition
The intelligent speed adaptation
informs the driver when a speed limit
is detected by the speed limit
recognition. The detected speed limit
can be taken over as new set speed
for the adaptive cruise control.
Using the camera at the top of the
windscreen, this system detects and
reads speed limit and end of speed
limit signs.
If the adaptive cruise control is active, the recognised speed limit will be
displayed in the Driver Information Centre and MEM illuminates if the
difference between set speed and
speed limit is more than 6 mph.
Press MEM on the steering wheel to
request saving of the suggested
speed.
Press MEM on the steering wheel
once more to confirm and save the
new speed setting.
This speed limit is now the new set
speed of the adaptive cruise control.

Vehicle messages 3 75.
Forward collision alert The forward collision alert may help toavoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera in the windscreen and
depending on the vehicle
configuration a radar unit located
behind the front bumper to detect a
vehicle directly ahead, in the path.
If a vehicle directly ahead is
approached too quickly, a warning
chime sounds and a message is
displayed in the Driver Information Centre.
9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.

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 40 mph. The alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.
The counting of driving time alert is
reset when the ignition has been
switched off for a few minutes.
Driver drowsiness detection The system monitors the driver's level
of vigilance at speeds above 40 mph.
A camera at the top of the windscreen detects variations in trajectory
compared to the lane markings.
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent
of the driver's level of vigilance.The driver drowsiness detection is
reinitialised when the ignition has
been switched off for a few minutes or the speed remains below 40 mph for
a few minutes.
