Changing target with Adaptive
Cruise Control
In combination with automatic gearbox, the
54
adaptive cruise control (ACC ) has functionality
for change of target at certain speeds.
Change of target
If the target vehicle in front suddenly turns then there
may be stationary traffic in front.
When adaptive cruise control is following another
vehicle at speeds below 30 km/h (20 mph) and
changes target from a moving to a stationary
vehicle, the adaptive cruise control will slow down
for the stationary vehicle.

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.
