Check the condition of the 12 volt
battery monthly by looking at the
test indicator window. The label on
the battery explains the test
indicator’s colors.
If your vehicle’s 12 volt battery is
disconnected or goes dead, the IMA
battery level gauge reading will not
be correct the next time you turn the
ignition switch to the ON (II)
position. It will show less than the
actual level temporarily. It will show
the correct level after you drive for
at least 30 minutes.
Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
further corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualified technician.
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative (
) cable first, and
reconnect it last.
WARNING:
Wash your hands af ter handling.

The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.
