To gain access to it:
F open the bonnet using the interior release

lever, then the exterior safety catch,

F secure the bonnet stay,
F lift the plastic cover on the (+) terminal.

First check that the slave battery has a
nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
Do not try to start the engine by
connecting a battery charger.
Do not disconnect the (+) terminal when
the engine is running.

F Connect the red cable to the positive

terminal (+) of the flat battery A, then to the
positive terminal (+) of the slave battery B.

F Connect one end of the green or black

cable to the negative terminal (-) of the
slave battery B (or earth point on the other
vehicle).

F Connect the other end of the green or

black cable to the negative terminal C (or
the engine mounting) of the broken-down
vehicle.

F Start the engine of the other vehicle and

Charging the battery using
a battery charger

Follow the instructions for use provided by

the manufacturer of the charger.

Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area
away from naked flames and sources
of sparks, so as to avoid the risk of
explosion and fire.
Do not try to charge a frozen battery;
the battery must first be thawed out to
avoid the risk of explosion. If the battery
has been frozen, before charging have
it checked by a CITROËN dealer or a
qualified workshop who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
corrosive acid.
Do not reverse the polarity and use only
a 12 V charger.
Do not disconnect the terminals while
the engine is running.
Do not charge the batteries without
disconnecting the terminals first.
Wash your hands afterwards.

Batteries contain harmful substances such
as sulphuric acid and lead. They must be
disposed of in accordance with regulations
and must not, in any circumstances, be
discarded with household waste.
Take used remote control batteries and
vehicle batteries to a special collection
point.

reduction function temporarily deactivates
certain functions, such as the air conditioning,
the heated rear screen...
The deactivated functions are reactivated
automatically as soon as conditions permit.

Energy economy mode

Exiting economy mode

These functions are reactivated automatically
the next time the vehicle is driven.
F In order to resume the use of these

functions immediately, start the engine and
let it run for a few minutes.

The time available to you will then be double
the period for which the engine is left running.
However, this period will always be between
five and thirty minutes.

Switching to economy mode

Once this period has elapsed, a message
appears on the multifunction screen indicating
that the vehicle has switched to economy mode
and the active functions are put on standby.

A flat battery prevents the engine from
starting (refer to the corresponding

charge in the battery.
After the engine has stopped, you can still use functions such as the audio equipment, windscreen
wipers, dipped beam headlamps, courtesy lamps, etc. for a maximum combined period of
thirty minutes.
This period may be greatly reduced if the battery is not fully charged.
