STARTING AND DRIVING 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 "Check Cruise System". If this messages appears on the display, see "Conventional cruise control mode failure warning" on page 349. If you turn off the main switch while the warning message is displayed, the warning message turns off and the multi-information display switches to another screen. When you turn the main switch on again, the warning message comes back on the display. If no warning message appears on the display, the setting can be made. You can change the dynamic 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 in the "CANCEL" direction. b. Depressing the brake pedal. c. Turning off the main switch. If cancelled by a. or b., the multi-information displays shows nothing and the conventional 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. In the following cases, the preset speed automatically cancels out: a. The vehicle speed falls below about 40km/h (25 mph). b. If the vehicle speed drops 16 km/h (10 mph) below the preset speed, the preset speed will also automatically be cancelled. c. The control lever is pressed downward in the "SET/COAST" direction and held at less than about 45 km/h (28 mph). (45 km/h (28 mph) is designated as a lower preset speed limit .) d. The slip indicator light blinks and a warning tone sounds. (This occurs when the vehicle is about to skid.) If the vehicle speed falls below about 40 km/h (25 mph), the preset speed data is cleared and you must set the speed from the beginning. If cancelled by the above cases, the multi-information displays shows nothing and the conventional cruise control enters the ready mode. If the preset speed automatically cancels out for other than the above reasons, do not operate the cruise control. Although it is no problem to continue driving, have your vehicle checked by your Lexus dealer at the earliest opportunity. 347
