Option/accessory, for more information, see Introduction.
WARNING
•
Adaptive Cruise Control is not a colli-
sion avoidance system. The driver is
always responsible for applying the
brakes if the system does not detect
another vehicle.
•
Adaptive Cruise Control does not react
to people or animals, or small vehicles
such as bicycles and motorcycles. It
also does not react to slow moving,
parked or approaching vehicles, or sta-
tionary objects.
•
Do not use Adaptive Cruise Control in
demanding driving conditions such as
city driving or other heavy traffic situa-
tions, in slippery conditions, when there
is a great deal of water or slush on the
road, during heavy rain or snow, in poor
visibility, on winding roads or on high-
way on- or off-ramps.
Fault tracing and actions
If the message
Radar blocked See manual
is
displayed, this means that the radar signals
from the sensor have been obstructed and that
a vehicle ahead cannot be detected.
This, in turn, means that the functions of the
ACC, Distance Alert, and Collision Warning
System with Auto-brake and Pedestrian
Detection will not function.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.
Cause
Action
The surface of the radar in the grille is dirty or obstructed in some way.
Clean the radar surface, or remove the object causing the obstruction.
Heavy rain or snow is interfering with the radar signals.
No action possible. Heavy precipitation may affect the function of the
radar.
