When the alarm is set off, the horn sounds for 30 seconds and the direction indicators flash for 5 minutes.
Starter and fuel pump relays as well as engine control system + 15 are immobilized for 30 minutes. Each attempt to start the car extends the
immobilization time by 30 minutes. If the ignition is on, these will be continuously immobilized as long as the alarm is armed.
To switch off an alarm that has been set off, it is disarmed in the normal way using the remote control.
Important: This type of alarm tripping is standard (at delivery). Flash and sound times can be reprogrammed as required by the local market.
