Driving with the doors locked could make
it more difficult for the emergency services
to enter the passenger compartment in an
emergency.
As a safety precaution, remove the key from
the ignition or take the electronic key with you
when leaving the vehicle, even for a short
time.
Purchasing a second-hand vehicle
Have the key codes memorised by a
CITROËN dealer, to ensure that the keys in
your possession are the only ones able to
start the vehicle.
Proximity Keyless Entry

on their person, the vehicle unlocks as they
approach and locks when they walk away.
If the electronic key is present in an area
between 2 and 7 m from the vehicle for more
than 30 minutes, the system is deactivated to
preserve the battery.
Key recognition zones:


Zone A: welcome lighting on approaching
the vehicle (between 3 and 5 metres from the
vehicle).
Zone B: automatic locking on leaving the vehicle
(about 2
metres from the vehicle).

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.
If the vehicle is unlocked but the doors or
boot are not subsequently opened, the
vehicle will automatically lock itself again after
about 30
seconds. If the vehicle is fitted with
an alarm, it will be reactivated automatically.
The automatic door mirror folding/ unfolding function is configured via the
touch screen's
Driving/Vehicle menu.
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.
