190 UNDERSTANDING THE FEATURES OF YOUR VEHICLE To decrease speed while speed control is set, press the SET/DECEL lever downward, and hold. Release the Electronic Speed Control lever when the desired speed is reached, and the new speed will be set. Tapping the SET/DECEL lever downward, once, will result in a 1 mph (1.6 km/h) speed decrease. Each time the Electronic Speed Control lever is tapped downward, speed decreases. Accelerating To Pass Press the accelerator as you normally would. When the pedal is released, the vehicle will return to the set speed. NOTE: The Electronic Speed Control system maintains speed up and down hills. A slight speed change on moderate hills is normal. 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 Control. WARNING! 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.
