CAUTION
D If other vehicles are driving outside of the millimeter
wave radar detection range, a delay in the detection
of the vehicle cutting in at short range or detection
failure of the motorcycle running on the side of the
same lane will occur. In this case, the dynamic radar
cruise control system will not function properly.
D When a slower vehicle in front of you leaves the lane,
the dynamic radar cruise control will no longer detect
a vehicle ahead and will attempt to accelerate the
vehicle to the faster preset speed.

(b) Turning the system on
G31011
To operate the dynamic radar cruise control, push the
"ON−OFF" button. This turns the system on. When the
"CRUISE" indicator light in the instrument cluster comes on
and "RADAR READY" appears on the multi−information
display, you can now set your desired cruising speed and
vehicle−to−vehicle distance. Pushing the "ON−OFF" button
again will turn the system completely off and "CRUISE OFF"
will appear on the multi−information display.
When the engine switch is turned off, the system is also
automatically turned off. To use the dynamic radar cruise
control again, push the "ON−OFF" button again to turn it on.
When the engine switch is turned off, all the preset data is
cleared. When you use the dynamic radar cruise control again,
you need to reset the data.
