Anti-theft protection
Electronic immobiliser
The key contains an electronic chip which has
a specific code. When the ignition is switched
on, this code must be recognised to enable the
vehicle to start.
This electronic immobiliser locks the motor
management system a few minutes after the
ignition is switched off and prevents the engine
being started by anyone who does not have
the key.
In the event of a fault, or if your vehicle does
not start, contact a CITROËN dealer as soon
as possible.
