STARTING AND DRIVING (e) Resetting to a faster speed Push the lever up in the "+ RES" direction and hold it. The displayed speed will increase in increments of 5 mph (for the U.S.A.) or 5 km/h (for Canada). Release the lever when the desired speed is attained. The vehicle speed will gradually increase to the displayed speed. However, a faster way to reset is to accelerate the vehicle and then push the lever down in the "- SET" direction. (f) Resetting to a slower speed Push the lever down in the "- SET" 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 speed will gradually decrease to the displayed speed. However, a faster way to reset is to depress the brake pedal and then push the lever down in the "- SET" direction. If the control lever is released when the vehicle speed exceeds the upper limit of the preset speed traveling downhill while you are pushing the lever down, the system will memorize the upper limit of the preset speed as a preset speed. With automatic transmission (standard type) - Even if you downshift the transmission from "D" to "4" 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. CAUTION When the vehicle-to-vehicle distance control is on, your cruising speed is regulated in proportion to the speed of the vehicle ahead, so increasing the preset speed using the control lever does not accelerate the vehicle. However, if the vehicle ahead leaves the lane, your cruising speed will increase to the preset speed because the preset speed has been set higher using the control lever. Confirm the setting on the display. 474
