out in a well ventilated area and away from
naked flames and sources of sparks, to avoid
any risk of explosion or fire.
Wash your hands afterwards.
Frozen battery
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 could lead to a risk of
leakage of toxic and corrosive acid.

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:

177
In the event of a breakdown
8– When 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
