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 by a key unlock operation in the driver's 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.
