Wheel theft-deterrent system (Dealer-installed)

Designed to help protect 20" and 22" wheels1, this available security system sets off your Sierra alarm system if the vehicle is jacked up or towed. The unit is wired directly into the vehicle's theft-deterrent system and will activate the alarm (horn and flashing lights) if its sensors detect a change in the parked angle of your vehicle.

Work Truck and SLE models require steering wheel-mounted audio controls.

1 Use only GM approved tire and wheel combinations. See dealer for details.
