STARTING AND DRIVING (b) Turning the system on G31015 G31011 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. 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. 407
