This system is responsible for making the power necessary to move the vehicle and sending that power to the wheels.
StabiliTrak® is an advanced computer controlled system that can help the driver maintain directional control of the vehicle in difficult driving conditions.
This system is responsible for monitoring and deployment of the air bag system.
This system is responsible for limiting the emissions from the vehicle, both by keeping fuel and its vapor contained in the fuel system, as well as by limiting exhaust tail pipe emissions by ensuring efficient engine operation.
This system is responsible for monitoring and controlling the antilock brakes, which can reduce stopping distance in slick conditions, and the traction control/stability system, which helps the vehicle maintain control in adverse conditions.
This system is responsible for the operation of your OnStar system.
This includes any routine maintenance determined by several factors such as mileage and oil life.
