Door Locking
Controlled by the BCU, the Central Door Locking (CDL) system controls the door locks.
The CDL system for each door consists of :
l
Door lock
l
Actuator
l
Recessed sill lock button.
The CDL system is operated by the remote handset externally from the driver's door lock or from the CDL switch
positioned on the fascia below the hazard warning switch. A safety feature prevents the doors from opening when a
set vehicle speed is exceeded (10 mph/16 kph).
NOTE: The operation of the door locks by any other means (for example the interior locking switch on the fascia panel)
will unlock the doors.
Single point entry is a security feature that enables the driver's door only to be unlocked using the remote handset or
key. By pressing the remote handset button once, or turning the key towards the front of the vehicle, the driver's door
only unlocks. By pressing the button on the remote handset or turning the key a second time, all the doors are
unlocked.
If the vehicle is unlocked using a single point entry, and if the CDL switch on the fascia is pressed, the driver's door
will relock. Pressing the CDL switch a second time unlocks all the doors.
