the door handle of one of the front doors to
unlock the vehicle or press the tailgate opening
control.
Flashing of the direction indicators for a
few seconds signals:
– the unlocking of the vehicle for versions without alarm,– the deactivation of the alarm for other versions.
For safety and theft protection reasons,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with you.
Accumulations (water, dust, grime, salt etc.) on the inner surface of the door
handle may affect detection.
If cleaning the inner surface of the door
handle using a cloth does not restore
detection, contact a CITROËN dealer or a
qualified workshop.
A sudden splash of water (stream of water,
high pressure jet washer, etc.) may be
identified by the system as the desire to open
the vehicle.
If one of the doors or the boot is still open
or if the electronic key for the Keyless
Entry and Starting system has been left inside the vehicle, central locking will be disabled.
However, if the vehicle is fitted with an alarm,
it will be activated after 45 seconds.
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 also be reactivated
automatically.
As a safety measure, never leave the vehicle, even for a short time, without
taking the Keyless Entry and Starting
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.
To preserve the battery charge in the electronic key and the vehicle's battery,
the "hands-free" functions are set to
hibernation mode after 21 days without use.
To restore these functions, press one of the
remote control buttons or start the engine with
the electronic key in the reader.
For more information on starting with the
Keyless Entry and Starting system, refer to

Advice
Remote control
The remote control is a sensitive, high-
frequency device; avoid handling it in your
pocket, due to the risk of unintentionally
unlocking the vehicle.
Avoid pressing the remote control buttons
while out of range of the vehicle, due to
the risk of rendering the remote control
inoperative. It would then be necessary to
reset it.
The remote control does not work when the key is in the ignition switch, even when the
ignition is switched off.
Anti-theft protection
Do not modify the electronic vehicle
immobiliser, as this might result in
malfunctions.
For vehicles with a key ignition switch,
remember to remove the key and turn the
steering wheel to engage the steering lock.
Locking the vehicle
Driving with the doors locked could make
it more difficult for the emergency services to
enter the vehicle 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.
In order to preserve the battery in the
electronic key and the vehicle's battery:
– All of the "hands-free" functions go into extended standby after 21 days of non-use.
To restore these functions, unlock the vehicle
using the remote control and start the engine.
Electrical interference
The electronic key may not operate if
close to certain electronic devices: telephone
(switched on or on standby), laptop computer,
strong magnetic fields, etc.
Do not throw remote control batteries away, as they contain metals that are
harmful to the environment. Take them to an
approved disposal point.
