STARTING AND DRIVING (b) Turning the system on D 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. D 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. To operate dynamic laser cruise control, press the "ON−OFF" button. This turns the system on. When the "CRUISE" and "READY" indicator lights in the instrument cluster come on, you can now set your desired cruising speed and vehicle−to−vehicle distance. Pressing the "ON−OFF" button again will turn the system completely off. When the ignition is turned off, the system is also automatically turned off. To use dynamic laser cruise control again, press the "ON−OFF" button again to turn it on. When the ignition is turned off, all the preset data is cleared. When you use the dynamic laser cruise control again, you need to reset the data. 423
