STARTING AND DRIVING After bringing the vehicle to the desired speed, press the control lever downward in the "- SET" direction and release it. This sets the vehicle at that speed. At this time, the multi−information display indicates settings such as the preset vehicle speed, whether a vehicle is present ahead and selected vehicle−to−vehicle distance. If there is no vehicle detected ahead, the dynamic radar/laser cruise control screen does not display the vehicle ahead. At this time, you may take your foot off the accelerator pedal. If you need to accelerate − for example, when passing − depress the accelerator pedal enough for the vehicle to exceed the preset speed. When you release the accelerator pedal, the vehicle will return to the control prior to acceleration. You cannot set a desired speed if the master warning light comes on, the warning tone sounds and the multi−information display indicates a warning message such as "Cruise not Available", "Clean Radar Sensor" or "Check Cruise System". If any of the above messages appears on the display, see "Vehicle−to−vehicle distance control mode failure warning" on page 353. If you turn off the "ON−OFF" button while the warning message is displayed, the warning message turns off and the multi−information display switches to another screen. If no warning message appears on the display, when you turn the "ON−OFF" button on again, the setting can be made. You can change the dynamic radar/laser cruise control screen to another screen even while the warning message is displayed. 2 Cancelling the preset speed You can cancel the preset speed by doing any of the following: a. Pulling the control lever toward you, in the "CANCEL" direction. b. Depressing the brake pedal. c. Pushing the "ON−OFF" button at the end of the cruise control lever. If cancelled by a. or b., the multi−information display shows "RADAR READY" and the dynamic radar/laser cruise control enters the ready mode. If cancelled by c., the "CRUISE" indicator light goes off in the instrument panel and the multi−information display shows "CRUISE OFF". In this case, the preset speed data is cleared, and you must set the speed from the beginning. 342
