Central Locking - CITROEN C4 Handbook

Access
It is not possible to lock the vehicle if the
electronic key is left inside the vehicle.
Deadlocking
Deadlocking renders the interior door
controls inoperative. It also deactivates
the central locking button.
The horn remains operational.
Never leave anyone inside the vehicle
when it is deadlocked.
► Gently press the driver's door handle to lock
the vehicle.
► Press it again within 3 seconds to deadlock
the vehicle (confirmed by the temporary lighting
of the direction indicators).
A double audible signal indicates that the vehicle
is not deadlocked.
Advice
If one of the doors or the boot is still open
or if the electronic key for the Keyless
Entry and Start system has been left inside
the vehicle, central locking will not take place.
36
If the vehicle is unlocked but the doors or
tailgate are not subsequently opened, the
vehicle will automatically lock itself again after
about 30 seconds. If fitted to the vehicle, the
alarm is automatically reactivated (if
previously activated).
Automatic folding/unfolding of the door
mirrors is configured in the touch screen.
For more information on Mirrors, refer to the
corresponding section.
As a safety measure, never leave the
vehicle, even for a short time, without
taking the Keyless Entry and Start system's
electronic key with you.
Be aware of the risk of theft of the vehicle if
the key is present in one of the defined areas
while the vehicle is unlocked.
In order to preserve the battery in the
electronic key and the vehicle's battery:
– The unlocking on approach function
(zone C) automatically switches to hibernation
mode after several days (approximately one
week) without being used. To unlock the
vehicle, use the remote control or press on
one of the door handles. The next time the
vehicle is started, the automatic unlocking
and locking functions will be reactivated.
– If the welcome lighting is triggered
several times in succession without the
vehicle subsequently being started, it will be
deactivated.
– All "hands-free" functions switch to
hibernation mode after 21 days without being
used. To restore these functions, unlock the
vehicle using the remote control and start the
engine.
Electrical interference
The electronic key may not work if it is
close to an electronic device (e.g. mobile
telephone (switched on or on standby), laptop
computer, strong magnetic fields). If this
occurs, move the electronic key away from
the electronic device.
