itself again after about 30 seconds.
If fitted to your vehicle, the alarm will also

handle using a cloth does not restore

Advice
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 (with children on
board), remove the key from the ignition or
take the electronic key when leaving the
vehicle, even for a short time.
Remote control
Deadlocking
The high frequency remote control is
a sensitive system; do not operate it while
it is in your pocket as there is a possibility
that it may unlock the vehicle, without you
being aware of it.
Do not press the buttons of your remote
control out of range of your vehicle.
It might stop working. It will then be
necessary to reinitialise it again.
The remote control does not operate when
the key is in the ignition switch, even when
the ignition is switched off.
Deadlocking deactivates the exterior
and interior door controls, as well as the
central locking button on the dashboard.
The horn remains operational.
You must therefore never leave anyone
inside the vehicle when it is deadlocked.
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
which can start the vehicle.
Electrical interference
The Keyless Entry and Starting electronic
key may not operate if close to certain
electronic devices: telephone, laptop
computer, strong magnetic fields, etc.
