Citroen C4 / Citroen C4 Owner's Manual / Access / Anti-intrusion alarm

Your vehicle may be equipped with an anti-intrusion alarm.

Your vehicle may be equipped with an anti-intrusion alarm.

This ensures:

• Exterior perimeter protection by means of detectors on the access points (doors, tailgate, bonnet) as well as on the electrical supply.
• Interior volumetric protection by means of ultrasonic sensors (detecting movement inside the passenger compartment).

This can be deactivated using control 1.

The installation also includes a siren and a warning lamp 2 visible from the

The installation also includes a siren and a warning lamp 2 visible from the outside, indicating the three possible alarm statuses:

• Alarm not armed (not on standby), warning lamp off.
• Alarm armed (on standby), the warning lamp flashes slowly.
• Alarm triggered (signalling an intrusion), the warning lamp flashes rapidly if the alarm is disarmed with a press on button B. It stops flashing as soon as you switch on the ignition.

Note: in the event of a malfunction, the warning lamp 2 comes on continuously.

Arming the alarm using the remote control

Switch off the ignition and leave the vehicle.

Ensure that all doors and the boot are closed.

Lock the vehicle using button A on the remote control.

When the alarm is armed, the protections become active within 5 seconds (perimeter) and 45 seconds (volumetric).

Triggering

Provided the alarm is armed, any intrusion triggers the siren for 30 seconds, accompanied by the illumination of the direction indicators.

The alarm then reverts to armed status, but the deployment remains memorised and is signalled by the rapid flashing of the alarm warning lamp 2 when you press the unlocking button B. The flashing stops when you switch on the ignition.

The siren is also triggered if there is a cutting of the electrical supply. To stop it, restore the electrical supply then give a press on the unlocking button B.

Disarming the alarm using the remote control

The alarm is disarmed when you unlock the vehicle (by pressing button B on the remote control).

Disarming the alarm using the key

Unlock the doors with the key. The siren is triggered. Enter the vehicle and switch on the ignition to stop the siren. Otherwise the siren will continue for about 30 seconds.

Note:

• If you wish to lock your vehicle without arming the alarm, just lock the vehicle with the key.
• If you try to lock your vehicle when a door or the boot is still open, the central locking will not operate, but your alarm becomes armed after approx. 45 seconds.

Note: the siren is automatically disarmed (for example if you need to disconnect the battery) immediately after you unlock the vehicle using the remote control.

Deactivation of volumetric detection

The alarm is able to operate with only perimeter protection if you deactivate the volumetric protection (if for example you wish to leave an animal in the vehicle).

To do this, switch off the ignition, then press immediately on control 1 for at least one second.

The warning lamp 2 should be on permanently. It will start to flash when the alarm activates.

Arm the alarm by locking your vehicle using the remote control.

Automatic activation (depending on country)

The alarm arms automatically 2 minutes after the boot or the last door is closed.

In order to prevent the alarm then being triggered by a door or the boot being opened, it is essential to press again on the unlocking button B on the remote control.
