Reinitialisation after

the ignition and wait at least one minute before
starting, to allow time for the initialisation of the
electronic systems.
By referring to the corresponding sections, you
should set or initialise the following systems
yourself:
- one-touch electric windows,
- time and date,
- audio and navigation system settings.
Check that no alert message or
warning lamp comes on after switching
on the ignition.
However, if minor problems persist
after carrying out these operations,
contact a CITROËN dealer or a
qualified workshop.

a battery charger

have to be disconnected for charging.
 Disconnect the battery from the vehicle.
 Follow the instructions for use provided by
the manufacturer of the charger.
 Connect the battery starting with the

 Check that the terminals and connectors
are clean. If they are covered with sulphate
(whitish or greenish deposit), remove them
and clean them.
