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

harmful to the environment. Take them to an
approved disposal point.
