TRACTION CONTROL AND STABILITRAK SYSTEMS The traction control system limits wheelspin and the StabiliTrak® stability control system assists with directional control of the vehicle in difficult ­ driving conditions. Both systems turn on automatically every time the vehicle is started. Turn off traction control if the vehicle is stuck and rocking the vehicle is required. Press the Traction Control/StabiliTrak Off button on the center of the instrument panel to turn traction control off or back on. The Traction Control Off light will illuminate on the instrument cluster when the ­ system is off. See Driving and Operating in your Owner Manual. HILL DESCENT CONTROLF (Z71) Hill Descent Control sets and maintains vehicle speed from 2-14 mph while descending a steep incline in a forward or reverse gear. 1. Press the Hill Descent Control button on the center of the instrument panel. Vehicle speed must be below 31 mph to enable the system. The Hill Descent Control symbol will illuminate on the instrument cluster. 2. Increase or decrease speed by applying the accelerator or brake pedal. The adjusted speed becomes the new set speed. The symbol flashes when the system is actively applying the brakes to maintain vehicle speed. See Driving and Operating in your Owner Manual. TIRE PRESSURE MONITOR (Single Rear Wheel Models Only) The Low Tire Pressure warning light on the instrument cluster illuminates when one or more of the vehicle's tires is significantly underinflated. Fill the tires to the proper tire pressures. The proper tire pressures for the vehicle are listed on the Tire and Loading Information label, located below the driver's door latch. Current tire pressures can be viewed in the Driver Information Center. Tire pressure is affected by cold weather and distance driven. If the low tire pressure warning light illuminates when the vehicle is first started in cooler temperatures and then ­ turns off as the vehicle is driven, check for the proper tire pressures. Refer to your Owner Manual for additional information about normal monthly tire maintenance. See Vehicle Care in your Owner Manual. F Optional equipment 19
