196 Driving and operating
Switching off the ignition also
switches off adaptive cruise control
and deletes the stored speed.
Driver's attention
● Use 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 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.
System limits
9 Warning
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.
● Adaptive cruise control does
ignore the oncoming traffic.
● Adaptive cruise control does not
consider pedestrians and
animals for braking and driving
off.
● Adaptive cruise control considers
stopped vehicles only at low
speed.
● Do not use adaptive cruise
control when towing a trailer.
● Do not use adaptive cruise
control on roads with an incline of
more than 10%.
Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may
lose the current vehicle ahead or
consider a vehicle which is not in the
actual lane. This can happen when
entering or exiting a bend or if the
bend gets stronger or weaker. If it no
longer detects any vehicle ahead,
then control indicator A will
extinguish.
