Controls in detail Driving systems Setting current speed Accelerate or decelerate to the desired speed. Briefly lift 1 or depress 2 the cruise control lever. The current speed is set. Remove your foot from the accelerator pedal. Cruise control is activated. The selected speed appears in the multifunction display for approximately five seconds, and the corresponding speedometer segments from the selected speed to the vehicle maximum speed are illuminated. Keep driver's foot area clear at all times, including the area under the brake pedal. Objects stored in this area may impair pedal movement which could interfere with the braking ability of the cruise control system. Do not place your foot under the brake pedal - your foot could become caught. Keep in mind that cruise control is a convenience system designed to assist the driver during vehicle operation. The driver is and must always remain responsible for the vehicle's speed and for safe brake operation. 1 Set current or higher speed 2 Set current or lower speed 3 Cancel cruise control 4 Resume to last set speed Warning! G Cruise control brakes automatically so that the set speed is not exceeded. The brake pedal depresses when the cruise control engages the brakes. i On uphill or downhill grades, cruise control may not be able to maintain the set speed. Once the grade eases, the set speed will be resumed. On downhill grades, the cruise control will hold the set speed with braking from the vehicle's brake system. In addition, on longer downhill grades the automatic transmission will automatically downshift. 268
