The engine immobilizer system prevents the
engine from being started in the event that an

unregistered key.
The security indicator light flashes to indicate that

The system sounds the alarm and flashes lights when forcible entry is detected.
To set the alarm: lock both side doors from outside the vehicle. The security indicator light
comes on to indicate that the alarm is in its preparation state. When the indicator light

To deactivate or stop the alarm: turn the “ENGINE START STOP” switch to ACCESSORY
or IGNITION ON mode, or unlock the doors or trunk using the electronic key or the wire-
less remote control.

START STOP” switch is OFF and the driver’s door

STOP” switch will flash and a message will be
shown on the multi-information display. To release
it, gently turn the wheel left or right while pressing
