STARTING AND DRIVING 3 Resetting to a faster speed 4 Resetting to a slower speed Press the control lever upward in the "RES/ACC" direction and hold it. The displayed speed will increase in increments of 5 mph (for U.S.A.) or 5 km/h (for Canada). Release the lever when the desired speed is attained. The vehicle will gradually increase to the displayed speed. Depressing the accelerator pedal and pressing the control lever downward in the "SET/COAST" direction will not reset to a faster speed. At this time the set speed falls by 5 mph (for U.S.A.) or 5 km/h (for Canada). Press the control lever downward in the "SET/COAST" direction and hold it. The displayed speed will decrease in increments of 5 mph (for U.S.A.) or 5 km/h (for Canada). Release the lever when the desired speed is attained. The vehicle will gradually decrease to the displayed speed. 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. Even if you downshift the transmission from "D" or "6" (sixth range) to "5" (fifth range), or from "D" or "5" (fifth range) to "4" (fourth range) in the vehicle-to-vehicle distance control mode, engine braking will not be enabled because this mode 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. 339
