If the vehicle ahead accelerates or
changes lane, the adaptive cruise
control progressively accelerates the
vehicle to return to the stored set
speed. If the driver operates a the turn
lights to overtake a slower vehicle, the adaptive cruise control allows the
vehicle to temporarily approach the
vehicle ahead to help passing it.
However, the set speed will never be
exceeded.
The adaptive cruise control can store
set speeds over 30 km/h for manual
transmission. If the vehicle ahead is
moving too slowly and the selected
following distance cannot be
maintained anymore, a warning
chime is given and a message is

166Driving and operatingAdaptive cruise control on
vehicles with automatic
transmission
For vehicles with automatic
transmission, adaptive cruise control allows to maintain the selected
distance behind a stopping vehicle until a complete stop is reached.
If the system has stopped your
vehicle behind another vehicle, then
the set speed is replaced by a green
control indicator .. This symbol
notifies, that the vehicle is hold
automatically in stop position.
If the stopped vehicle ahead was

last stored set speed remains in
memory for later usage.
The 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

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.
