Speed related locking For added protection the vehicle doors can automatically lock when the vehicle exceeds a specific road speed.

There are two configurations for speed related locking: l Speed related locking not active. l Speed related locking active.

Speed related locking causes the doors to automatically lock when the vehicle exceeds a speed of 4 mph (7 km/h). When the ignition is switched off, the doors are automatically unlocked. Depressing the instrument panel mounted central door unlocking switch disables the speed related locking for the duration of the journey.

Speed related locking only activates once per ignition cycle. If speed related locking activates and a door is then unlocked, the door does not automatically re-lock.

In order for speed related locking to activate the following conditions must be met: l All doors unlocked. l Engine running. l Vehicle speed greater than 4 mph (7 km/h).

Acclimatisation related locking Acclimatisation related locking allows the engine to be started and then the vehicle locked with a spare key and left unattended to allow the vehicle interior to reach the desired temperature.

There are two configurations for acclimatisation related locking: l Acclimatisation related locking not active. l Acclimatisation related locking active.

Once the engine is started, the vehicle is locked with a spare key at the driver's door while the engine is running. During these conditions the alarm is not armed.

In order to activate acclimatisation related locking the following conditions must be met: l Engine running. l All doors closed.

Visual warnings The direction indicators serve as a visual indication when the alarm is triggered. The direction indicators are also used as a visual indication during lock/unlock procedures.

There are three configurations of alarm armed/disarmed indication: l No direction indicators on, alarm armed/disarmed/trigger. l Direction indicators on, alarm trigger only. l Direction indicators on, alarm armed/disarmed/trigger.

Dependent on system configuration the direction indicators flash one short pulse to confirm that the alarm is armed and flash two short pulses to confirm that the vehicle is super locked. If the alarm is triggered the direction indicators operate in phase with the audible warning. When the alarm is disarmed, the direction indicators flash one long pulse.

Audible warning An audible warning device is used to indicate that the alarm has been triggered, or a mislock has occurred, or an EKA request has occurred, or the EKA code has been entered.

There are six audible warning configurations: l No sound (audible warnings disabled). l Alarm sounder only. l Vehicle horn only. l Alarm sounder and vehicle horn. l BBUS only. l Alarm sounder, vehicle horn and BBUS.
