command uses its own wire. The control of the security system and the keyless entry system are
usually commanded together although independent control is possible.
The driver of the vehicle can call OnStar from a separate phone and request that the vehicle be
locked, unlocked or security system turned on or off.

beep the horn. This is performed if the driver calls OnStar from a separate phone to assist with
locating the vehicle.
