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

are informed by illumina-

screen.
In this case, your vehicle will not start;
contact a CITROËN dealer as soon as
possible.
Keep safely, away from your
vehicle, the label attached to the
keys given to you on acquisition
