Central Locking

The vehicle can be locked and unlocked by three methods; CDL switch, vehicle key or remote handset.

CDL Switch

The CDL switch is located in the centre console. The CDL switch allows the occupants to CDL lock the vehicle from inside without arming the alarm. The CDL switch is inoperative if the inertia switch is tripped. The CDL locked state can be removed by operation of the CDL switch, remote handset or key unlock in the drivers door key barrel. If the inertia switch is tripped while the doors are CDL locked and the ignition is on, all doors will automatically unlock.

Key locking

The vehicle can be CDL locked using the vehicle key in the driver’s door key barrel. Turning the top of the key to the rear of the vehicle will CDL lock all doors. Turning the key a second time, within one second of the first turn, will superlock all doors.

Key Unlocking

On vehicles with alarm selected:

With the vehicle CDL or superlocked, turning the top of the key once to the front of the vehicle will mechanically unlock the driver’s door only. The vehicle will enter the Emergency Key Access (EKA) state. Refer to Emergency Key Access (EKA) in this section.

On vehicles with alarm not selected (market option):

With the vehicle CDL locked, turning the top of the key once to the front of the vehicle will unlock all the doors.

If the vehicle is superlocked, turning the top of the key once to the front of the vehicle will only unlock the driver’s door for Single Point Entry (SPE). The remaining door(s) will unlock to the CDL state. If the key is turned a second time, the remaining door(s) will unlock.

NOTE: If the vehicle is superlocked and SPE has not been selected in the CCU, turning the top of the key once to the front of the vehicle will unlock all the doors.
