STARTING AND DRIVING 4 Resetting to a slower speed Cruise control failure warning If the "CRUISE" indicator light in the instrument cluster flashes when using the cruise control, push the main switch to turn the system off and then push it again to turn it on. If any of the following conditions then occurs, there is some trouble in the cruise control system. D The indicator light does not come on. D The indicator light flashes again. D The indicator light goes out after it comes on. If this is the case, contact your Lexus dealer and have your Lexus inspected. Press the control lever downward in the "− / SET" direction and hold it. Release the lever when the desired speed is attained. While the lever is held downward, the vehicle speed will gradually decrease. When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can be lowered 1.6 km/h (1 mph) each time by pressing the control lever downward in the "− / SET" direction quickly within 0.6 seconds. However, a quicker way to reset is to depress the brake pedal and then press the control lever downward in the "− / SET" direction. Even if you downshift the transmission from the "D" position to "4" position with the cruise control on, engine braking will not be applied because the cruise control is not cancelled. To decrease the vehicle speed, reset to a slower speed with the cruise control lever or depress the brake pedal. If you use the brake pedal, cruise control is cancelled. 5 Resuming the preset speed If the preset speed is cancelled by pulling the control lever or by depressing the brake pedal, pushing the lever up in the "+ / RES" direction will restore the speed set prior to cancellation. However, once the vehicle speed falls below about 40 km/h (25 mph), the preset speed will not be resumed. 314
