STARTING AND DRIVING (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. With automatic transmission (multi−mode type) - Even if you downshift the transmission from "D" or "5" (fifth range) to the "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. (g) Resuming the preset speed If the preset speed has been cancelled, when you push the lever up in the "+ RES" direction while the "READY" indicator in the instrument cluster comes on at a vehicle speed of more than 40 km/h (25 mph), the speed set prior to cancellation will be restored. During follow−up cruising, if there are no vehicles ahead because they have changed lanes, your vehicle will accelerate gradually up to the preset speed. At this time, pushing the lever up in the "+ RES" direction will quickly speed up your vehicle in vehicle−to−vehicle distance control mode. 426
