In the event of an accident in which the air-

bags inflate, the doors will be automatically

unlocked to facilitate access and assistance.

If it does not flash, this indicates that one of

the doors, the rear lid or the bonnet is not

closed correctly.

The vehicle can be locked and unlocked via

the central locking system. There are several

methods, depending on the vehicle equip-

ment:

Anti-theft alarm system*

Accidental lock-out

If the anti-theft alarm system senses interfer-

ence with the vehicle it triggers an audible

and visible alarm.

The central locking system prevents you from

ing situations:

Unlocking one side of the vehicle only

Lock the vehicle with the remote control key,

when all the doors and the rear lid have been

closed. This prevents the accidental locking

of the vehicle.

When the driver door is unlocked with the key,

you should switch on the ignition within 15

seconds. Otherwise the alarm will be trig-

gered. On some export versions, the alarm is

triggered immediately when you open a door.

When you lock the vehicle with the key, the

doors and the rear lid are locked. When you

open the door, you can either unlock only the

driver door, or all the vehicle doors. To select

the required option, use Easy Connect*

WARNING

To deactivate the alarm, press the  button

on the remote control key, or switch on the ig-

nition. After a certain time, the alarm will au-

tomatically switch off.

gency, potentially putting lives at risk.
