BATTERY
The battery is
one of
the most
i
mportant
compo·
nents in the car and must, therefore, be
care-
fully maintained. The electrolyte should be
level
with the lower edge
of
the filler
pipes.
Top up as
necessary using distilled water
only.
In the case
of cars
that are equipped with a
maintenance-free battery, the electrolyte level
does not need
checking.
WARNING! The battery contains diluted
sulphuric acid which is highly corrosive.
Should the acid come into contact with
your
eyes,
skin or clothing. rinse imme·
diately with
water.
Call a doctor if the
acid gets in your
eyes.
Batteries that are
being charged or are fully charged give
off flammable hydrogen
gas.
The battery charge sh
o
uld be checked at regu-
lar intervals. This is
espec
ially important during
the winter when the
capac
ity drops due to low
temperatures.
Never connect the battery cables to the wrong
terminals.
