196 UNDERSTANDING THE FEATURES OF YOUR VEHICLE Your vehicle may experience a downshift (automatic transmissions only) while climbing uphill or descending downhill. This downshift is necessary to maintain vehicle set speed. On steep hills, a greater speed loss or gain may occur, so it may be preferable to drive without Electronic Speed The Rear Park Assist will remember the last system state Control. (enabled or disabled) from the last ignition cycle, when WARNING! the ignition is changed to the RUN/ON position. Electronic Speed Control can be dangerous where the system cannot maintain a constant speed. Your vehicle could go too fast for the conditions, and you could lose control. An accident could be the result. Do not use Electronic Speed Control in heavy traffic or on roads that are winding, icy, snow-covered, or slippery. The Rear Park Assist can be active only when the shift lever is in REVERSE. When in REVERSE, the system scans for objects behind the vehicle, using four sensors located in the rear bumper. NOTE: The system will be active until the vehicle speed is increased to approximately 11 mph (18 km/h) or above. The system will be active again if the vehicle speed is decreased to speeds less than approximately 10 mph (16 km/h). REAR PARK ASSIST - IF EQUIPPED The Rear Park Assist provides visible and audible indications of the distance between the rear fascia and the detected obstacle, when backing up. When backing up, you should also use the inside rearview and outside mirrors.
