178 UNDERSTANDING THE FEATURES OF YOUR VEHICLE To Accelerate For Passing Depress the accelerator as you would normally. When the pedal is released, the vehicle will return to the set speed. NOTE: When driving uphill, at elevations above 2,000 feet (610 meters), or when the vehicle is heavily loaded (especially when towing) the vehicle may slow below the SET speed. If the vehicle speed drops below (refer to the table below for the speed for your specific engine), the speed control will automatically disengage. If this happens, you can push down on the accelerator pedal to maintain the desired speed. Vehicles equipped with a 5-speed-manual transmission should be operated in 4th gear or lower under the above conditions. Vehicles equipped with a Automatic transmission may exhibit several downshifts under the above conditions. To reduce the frequency of the downshifts and to improve vehicle performance, it is advisable to use either TOW HAUL or O/D OFF modes which can be selected by pressing the "TOW HAUL O/D OFF" button located at the end of the gear shifter. WARNING! Speed Control can be dangerous where the system can't maintain a constant speed. Your vehicle could go too fast for the conditions, and you could lose control. An accident could be the result. Don't use Speed Control in heavy traffic or on roads that are winding, icy, snow-covered, or slippery.
