Avoiding a discharged battery
Turn off the headlights and the audio system while the engine is off.
Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
Charging the battery
The electricity stored in the battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects
of certain electrical appliances. If the vehicle is left for a long time, the
battery may discharge, and the engine may be unable to start. (The bat-
tery recharges automatically during driving.)
CAUTION
Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended ter-
minal.
Do not allow the jumper cables to come into contact with the “+” and “-”
terminals.
Do not allow open flame or use matches, cigarette lighters or smoke near
the battery.

When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, cloth-
ing or the vehicle body.
Do not lean over the battery.
