Security (Alarm System): Description and 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 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: 1 the ignition is switched off and the driver's door is opened and closed 2 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.

Latch Motor Protection To protect the door lock latches from damage, the CCU will only allow eight changes of state of the locks in any sixteen second period or less. If eight changes of state occurs within the sixteen second period, the CCU will prevent further operation of the latch motors for a further sixteen second period. The CCU will always prevent further operation only when the latch motors are in an unlocked condition. If SPE is operational, the CCU will override the SPE function and all doors will unlock if eight operations is exceeded in the sixteen second period.

The alarm system will continue to operate during the latch motor protection period.

Alarm System

The alarm system can be armed and disarmed using the vehicle key or the remote handset. The alarm system monitors the driver's door, passenger door(s), tail door, bonnet and roof (3 door models only) using perimetric sensing. It also monitors movement within the passenger compartment using volumetric sensing.

In certain countries, the alarm system is programmed not to arm under any circumstances.

NOTE: Hazard warning light confirmation of alarm arm or disarm is market programmable and therefore may not be operative on certain market variants.
