immobiliser, as this might result in
malfunctions.

remember to remove the key and turn the
steering wheel to engage the steering lock.

Access
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.
Proximity Keyless Entry
and Start
This is a Keyless Entry and Start system.

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).

about 30
seconds. If the vehicle is fitted with
an alarm, it will be reactivated automatically.

the key is present in one of the defined areas
while the vehicle is unlocked.
In order to preserve the battery in the
