Charging The Battery Using A Battery Charger; Disconnecting The Battery - CITROEN C5 AIRCROSS Handbook

Charging the battery using
a battery charger
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances, it may be necessary to
charge the battery:
- using the vehicle mainly for short journeys,
- if the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.
To charge the vehicle's battery yourself,
use only a charger compatible with lead-
acid batteries with a nominal voltage of
12 V.
Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities.
It is not necessary to disconnect the
battery.
F Switch off the ignition.
F Switch off all electrical consumers (audio
system, lighting, wipers, etc.).
F Switch off charger B before connecting the
cables to the battery, so as to avoid any
dangerous sparks.
F Ensure that the charger cables are in good
condition.
F If the vehicle has one, lift the plastic cover
on the (+) terminal.
F Connect the cables of charger B as follows:
- the positive (+) red cable to the (+)
terminal of battery A,
- the negative (-) black cable to earth point
C on the vehicle.
F At the end of the charging operation, switch
off charger B before disconnecting the
cables from battery A.
In the event of a breakdown
Never try to charge a frozen battery – risk
of explosion!
If the battery has frozen, have it checked
by a CITROËN dealer or by a qualified
workshop who will verify that the internal
components have not been damaged
and that the case has not cracked, which
would mean a risk of toxic and corrosive
acid leaking.
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.

Disconnecting the battery

In order to maintain an adequate state
of charge for starting the engine, it is
recommended that the battery be disconnected
if the vehicle is taken out of service for a long
period.
Before disconnecting the battery:
F close all openings (doors, tailgate, windows,
sunroof),
F switch off all electrical consumers (audio
system, wipers, lighting, etc.),
