STARTING AND DRIVING
428
Dynamic laser cruise control should not be used in
circumstances which are inappropriate for any cruise control,
such as entering free way on
−
ramps or off
−
ramps.
CAUTION
Do not use dynamic laser cruise control when exiting
from or when entering or merging onto a freeway.
When you are following a slower moving vehicle and
exiting, the sensor does not detect the vehicle and
will accelerate to the preset speed.
If other vehicles are driving outside of the laser radar
detection range, a delay in the detection of the
vehicle cutting in at short range or failure to detect a
motorcycle running on the side of the same lane will
occur. In this case, the dynamic laser cruise control
system will not function properly.
When a slower vehicle in front of you leaves the lane,
the dynamic laser cruise control will no longer detect
a vehicle ahead and will attempt to accelerate the
vehicle to the faster preset speed.
