Using Cruise Control on Hills How well the cruise control will work on hills depends upon the vehicle speed, load, and the steepness of the hills. While going up steep hills, you might have to step on the accelerator pedal to maintain the vehicle's speed. While going downhill, you might have to brake or shift to a lower gear to keep the vehicle's speed down. Of course, applying the brake turns off the cruise control. Many drivers find this to be too much trouble and do not use cruise control on steep hills. Exterior Lamps The exterior lamps control is located on the instrument panel to the left of the steering wheel. It controls the following systems: Ending Cruise Control There are three ways to end cruise control: • Step lightly on the brake pedal. • Press the cancel button on the steering wheel. • Press the On/Off button on the steering wheel. Erasing Speed Memory When the cruise control or the ignition is turned off, the cruise control set speed memory is erased. Headlamps Taillamps Parking Lamps License Plate Lamps Instrument Panel Lights The exterior lamps control has four positions: O(Off): Turn the control to this position to turn off the automatic headlamps and daytime running lamps (DRL). Turn the headlamp control to the off position again to turn the automatic headlamps or DRL back on. For vehicles first sold in Canada, the off position will only work when the vehicle is shifted into PARK (P). 3-14
