WARNING
When the adaptive cruise control is following
another vehicle at speeds in excess of
approx. 30 km/h (20 mph) and the target is
changed from a moving vehicle to a stationary
vehicle, the adaptive cruise control will ignore
the stationary vehicle and instead accelerate
to the stored speed.
The driver must then intervene him/
•
herself and brake.
Automatic standby mode with change of
target
The adaptive cruise control is disengaged and set
in standby mode:
when the speed is below 5 km/h (3 mph)
•
and the adaptive cruise control is uncertain
whether the target object is a stationary vehi-
cle or some other object, such as a speed
bump.
when the speed is below 5 km/h (3 mph)
•
and the vehicle ahead turns off so the adap-
tive cruise control no longer has a vehicle to
follow.

Cessation of automatic braking
