The camera/radar sensor measures the distance to
the vehicle ahead.
Adaptive Cruise Control can help provide a
more relaxed driving experience on long trips
on highways or long, straight roads with even
traffic flows.
The driver sets a speed and a time interval to
the vehicle ahead. If the camera/radar sensor
detects a slower-moving vehicle ahead, your
vehicle's speed will be automatically adapted
according to the set time interval to that vehi-
cle. When there are no longer slower-moving

vehicles ahead, the vehicle will return to the
set speed.

smoothly regulate speed. The driver must
•
apply the brakes in situations requiring
immediate braking. For example, when
there are great differences in speed
between vehicles or if the vehicle ahead
brakes suddenly. Due to limitations in the
radar sensor, braking may occur unexpect-
edly or not at all.
follow a vehicle ahead in the same lane
•
and maintain a time interval to that vehicle
set by the driver. If the radar sensor does
not detect a vehicle ahead, it will instead
maintain the speed set by the driver. This
will also happen if the speed of the vehicle
ahead exceeds the set speed for your vehi-
cle.
