Volumetric Sensing
Volumetric mode monitors the vehicle interior for intrusion. If the vehicle is fitted with a BBUS, which incorporates a tilt sensor, the vehicle attitude is also monitored when volumetric sensing is active. On Double Locking Vehicles volumetric sensing is activated by a second press of the lock switch on the smart key/Keyless vehicle exterior lock switch. The second press of the switch must occur within 3 seconds of the first press. The second press of the lock switch also activates the perimeter mode double locking feature.
On Single Locking, vehicles where volumetric sensors are fitted, Volumetric Sensing is activated by a single press of the lock switch on the smart key/Keyless vehicle exterior lock switch.
The BCM/GWM arms the active anti-theft system when it single locks or double locks the vehicle, providing all the following conditions are met:
- All doors, tailgate and hood are closed.
- The BCM/GWM is not in transit mode.
When the vehicle has successfully completed its locking routine, confirmation will be given by a single short flash of the turn signal indicators to indicate a single locked condition. If double locking is activated, then the confirmation will be given by a double flash of the turn signal indicators; one short flash for locked and one long flash on completion of double locked.
