Charging the battery using
a battery charger
With Stop & Start, the battery does not
have to be disconnected for charging.
F Disconnect the battery from the vehicle.
F Follow the instructions for use provided by
the manufacturer of the charger.
F Connect the battery starting with the
negative terminal (-).
F Check that the terminals and connectors
are clean. If they are covered with sulphate
(whitish or greenish deposit), remove them
and clean them.
Before disconnecting the battery
Wait 2 minutes after switching off the ignition
before disconnecting the battery.
Close the windows and the doors before
disconnecting the battery.
Disconnecting the (+) cable
F Raise the locking tab D fully to release the
cable terminal clamp E.
Reconnecting the (+) cable
F Position the open clamp E of the cable on
the positive post (+) of the battery.
F Press vertically on the clamp E to position
it correctly on the battery.
F Lock the clamp by spreading the
positioning lug and then lowering the tab D.
Do not apply excessive force on the
tab as locking will not be possible if the
clamp is not positioned correctly; start
the procedure again.
In the event of a breakdown
Reinitialisation after
reconnection
After any reconnection of the battery, switch on
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.
