HILL DESCENT CONTROLF (X31)
INTEGRATED TRAILER BRAKE CONTROL (ITBC)F
Hill Descent Control sets and maintains vehicle speed from 1–14 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 or use the Cruise Control +/– buttons on the steering wheel. 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’s Manual.
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 dis-played on the Driver Information Center.

control panel (left lever does not move) to manually apply the trailer brakes.

The trailer app will remember your Trailer Gain adjustments for each trailer profile.

TIRE PRESSURE MONITOR

Fill the tires to the proper tire pressures listed on the Tire and Loading Information label, located below the driver’s door latch. Current tire pressures can be viewed on the Driver Information Center.
The Tire Fill Alert provides visual and audible alerts to help when inflating a tire to the recommended tire pressure (does not apply to spare tire). When the recommended pressure is reached, the horn sounds and the turn signals change from flashing to solid.
Refer to your Owner’s Manual for information about normal monthly tire maintenance.
