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.
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:
►

Close all openings (doors, boot, windows,
roof). ►


Switch off all electrical consumers (audio
system, wipers, lighting, etc.).
►

Switch off the ignition and wait for 4
minutes.
At the battery, it is only necessary to disconnect
the (+) terminal.

Do not force the lever as locking will be
impossible if the clamp is not positioned
correctly; start the procedure again.
After reconnection
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, to enable the electronic systems to
initialise.

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 exterior temperature and the
state of charge of the battery (up to about 8
hours).
Accessory battery (Rechargeable hybrid)
The rechargeable hybrid system has two
accessory batteries: one at the front and one at
the rear of the vehicle.
The batteries contain harmful substances (sulphuric acid and lead).
They must be disposed of in accordance
with regulations and must never under any
circumstances be discarded with household
waste.
