118 UNDERSTANDING THE FEATURES OF YOUR VEHICLE To decrease speed while the Electronic Speed Control is set, push down and hold the SET DECEL lever. If the lever is continually held in the SET DECEL position, the set speed will continue to decrease until the lever is released. Release the lever when the desired speed is reached, and the new set speed will be established. Tapping the SET DECEL lever once will result in a 1 mph (2 km/h) speed decrease. Each time the lever is tapped, vehicle speed decreases. To Accelerate for Passing Press the accelerator as you would normally. When the pedal is released, the vehicle will return to the set speed. Using Electronic Speed Control On Hills The transmission may downshift on hills to maintain the vehicle set speed. NOTE: The Electronic Speed Control System maintains speed up and down hills. A slight speed change on moderate hills is normal. 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.
