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 left side 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. INTEGRATED TRAILER BRAKE CONTROL (ITBC)F The ITBC system can be used to adjust the amount of power output, or Trailer Gain, available to the trailer brakes. The control panel is located on the left side of the instrument panel. ITBC information is displayed on the Driver Information Center. Adjust the Trailer Gain by pressing the +/- adjustment buttons on the control panel. Slide the lever to the left on the control panel to manually apply the trailer brakes. See Driving and Operating in your Owner Manual. TOW/HAUL MODE The Tow/Haul Mode adjusts the transmission shifts to reduce shift cycling, such as when towing or hauling heavy loads or driving on steep grades. Press the Tow/Haul Mode button on the end of the shift lever to turn the system on or off. See Driving and Operating in your Owner Manual. TIRE PRESSURE MONITOR 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. F Optional equipment See Vehicle Care in your Owner Manual. 19
