Disconnecting the battery
It is recommended that the battery be
disconnected if the vehicle is not to be used
for a very long period, so as to maintain an
adequate state of charge for starting the
engine.
Before disconnecting the battery:
F close all openings (doors, boot, windows,
roof),
F switch off all electrical consumers (audio
system, wipers, lighting...),
F switch off the ignition and then wait
four minutes.
At the battery, simply detach the (+) terminal.
Quick-release terminal
Disconnecting the (+) cable
F Raise the lever 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 lever 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
Following reconnection of the
battery
Following reconnection of the battery, switch on
the ignition and wait 1 minute before starting to
permit initialisation of the electronic systems.
However, if problems remain following this
operation, contact a PEUGEOT dealer or a
qualified workshop.
Referring to the corresponding section, you
must yourself reinitialise (depending on
version):
- the remote control key,
- ...
The Stop & Start system may not be
operational during the trip following the
first engine start.
In this case, the system will only be
available again after a continuous
period of immobilisation of the vehicle,
a period which depends on the ambient
temperature and the state of charge of
the battery (up to about 8 hours).
