STARTING AND DRIVING In the following cases, the warning messages appear and the preset speed automatically cancels out. When dynamic laser cruise control is restored, the warning messages turn off and dynamic laser cruise control enters "RADAR READY" mode. a. The slip indicator light blinks and a warning tone sounds. (This occurs when the vehicle is about to skid.) b. The wipers are operated at high or low speeds (including high and low speed operations with the wiper lever in the "AUTO" position.) c. The driving pattern selector switch is set to "SNOW" mode. d. The anti−lock brake system is activated by automatic braking. (The warning tone sounds.) e. The sensor does not operate properly because a foreign matter sticks to the sensor. 3 Resetting to a faster speed Press the control lever upward in the "RES/ACC" direction and hold it. Release the lever when the desired speed is attained. While the lever is held upward, the vehicle will gradually gain speed. A quicker way to reset the speed is to accelerate and then press the control lever downward in the "SET/COAST" direction. 4 Resetting to a slower speed Press the control lever downward in the "SET/COAST" direction and hold it. The vehicle starts to decelerate from the speed at which the lever is operated. Release the lever when the desired speed is attained. While the lever is held downward, the vehicle speed will gradually decrease. A quicker way to reset the preset speed is to depress the brake pedal and then press the control lever downward in the "SET/COAST" direction. If the control lever is released when the vehicle speed exceeds the upper limit of the preset speed traveling downhill while you are pressing the control lever downward, the system will memorize the upper limit of the preset speed as a preset speed. Shifting the transmission from "D" to "4" will not slow your vehicle as it does when the dynamic laser cruise control is not engaged. To slow down, reset the cruise control to a slower speed with the cruise control lever or depress the brake pedal. If you use the brake pedal, cruise control is cancelled. NOTICE If the preset speed automatically cancels out for other than the above reasons, do not operate the dynamic laser cruise control and have your vehicle checked by your Lexus dealer at the earliest opportunity. 261
