Anti-theft protection
Electronic engine immobiliser
The key contains an electronic chip which has a special code. When the ignition is switched on, this code must be recognised in order for starting to be possible.
This electronic engine immobiliser locks the engine management system a few minutes after the ignition is switched off and prevents starting of the engine by anyone who does not have the key.

In the event of a malfunction, you are informed by lighting of this warning lamp, an audible signal and a message on the multifunction screen.
In this case, your vehicle does not start; contact a CITROËN dealer as soon as possible.
