– to avoid creating a short circuit be- tween the terminals, do not place
metal objects on the battery;
– always wait at least one minute after the engine has been switched off
before disconnecting a battery;
– make sure that you reconnect the battery terminals after refitting.
Connecting a battery charger
The battery charger must be com-

Avoid all risk of sparks which may
cause an immediate explosion, and
charge the battery in a well venti-
lated area.

Handle the battery with care
as it contains sulphuric acid,
which must not come into
contact with eyes or skin. If
it does, wash the affected area with
plenty of cold water. If necessary,
consult a doctor.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion. There is a risk of
explosion.
The engine may be hot when car-
