DESCRIPTION AND OPERATION

86-5-5

Key Unlocking
Single point entry is a programmable feature and its selection affects how the vehicle responds to key unlock 
requests:

l

Turning the top of the key once towards the front of a vehicle which is in a CDL state, with the alarm disarmed, 
will unlock all the doors irrespective of their existing lock status

l

Turning the top of the key once towards the front of a vehicle in a superlocked state without SPE selected and 
the alarm armed, will unlock all the doors irrespective of their existing lock status

l

Turning the top of the key once towards the front of a vehicle in a superlocked state with SPE selected and the 
alarm armed, will unlock the driver's door. The remaining doors will unlock to the CDL state and can be unlocked 
with a further key unlock operation

Remote Locking
On vehicles with superlocking selected the vehicle can be superlocked by pressing the lock button on the remote 
handset once. On vehicles with superlocking not selected (market option) the vehicle can be CDL locked by pressing 
the lock button on the remote handset once.

Remote Unlocking
With the vehicle CDL locked, pressing the unlock button on the remote handset once will unlock all doors.

If the vehicle is superlocked, pressing the unlock button once on the remote handset will only unlock the drivers door 
for SPE. The remaining door(s) will unlock to the CDL state. If the button is pressed a second time, the remaining 
door(s) will unlock.

NOTE: If the vehicle is superlocked and SPE has not been selected in the CCU, pressing the unlock button once on 
the remote handset will unlock all the doors.

Central Locking Notes
Locking or unlocking using the vehicle key or remote handset is prevented if the CCU senses that the ignition is 'on'. 
Using the key to lock the vehicle via the driver's key lock with the ignition 'on' will mechanically lock the driver's door.

Superlocking is prevented if the CCU senses that one or more doors are open. In this instance the CCU will attempt 
to CDL lock all doors.

Inertia Switch
The inertia switch is located on the bulkhead in the engine compartment. The switch is mounted vertically and has a 
reset button on its top surface, covered by a rubber boot.

If the inertia switch is tripped, with the ignition 'on' and the alarm disarmed, all the doors will be unlocked regardless 
of their locked state at that time. Further locking is disabled unless:

the ignition is switched off and the driver's door is opened and closed
the driver's door is opened and closed and the inertia switch is manually reset

The inertia switch can be reset by depressing the button on the top of the switch.

Tail Door
The CCU also controls the tail door release. The tail door can only be opened if the vehicle is unlocked, the alarm is 
not armed and the vehicle is travelling at not more than 3 mph (5 km/h).

Slam Locking
The driver's door is designed to prevent slam locking. The remaining door(s) can be slam locked.
