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 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.
