Alarm system and hornConfigurable system functions · page 7 of 7

Depending on which market the vehicle is sold, either the vehicle horn, a specific alarm sounder, or a BBUS operates in phase with the direction indicators when the alarm is triggered. The audible warning device operates for approximately 30 seconds at 0.25 second on, and 0.25 second off. The BCU allows the alarm to be triggered up to 3 times in any armed period.

There are eight theft deterrent alarm configurations: l No handset low battery warning. l Handset low battery warning. l No passive immobilisation. l Passive immobilisation. l Engine immobilised (ignition off, LED off). l Engine immobilised (ignition off, LED flashes). l No alarm tampered indication. l Alarm tampered indication.

The theft deterrent LED utilises a particular flash to show the status of the following: l Alarm armed. l Engine immobilised. l Alarm tampered. l Handset low battery warning.

The following functions are disabled when the vehicle is in transit mode: l Volumetric sensors. l Passive immobilisation. l Mobilisation of the vehicle by use of door lock. l Ignition key interlock. l Electric seat enable time-out with drivers door open.

To exit this mode, switch on the ignition and simultaneously hold down the heated rear window and the rear fog lamp switch for 2 seconds.
