Electrical System
However, if your battery is discharged (dead), you may be
able to start it by using energy from a good battery in another
vehicle. This is termed “jump starting.” Be sure to follow the
precautions and instructions below.
WARNING! Batteries contain acid that can burn
and gases that can explode. Ignoring safety procedures
can cause you or others to be badly
hurt.
WARNING! Never jump start a battery near fire,
flames, or electrical sparks. Batteries generate
explosive gases that could explode causing
serious personal injury. Keep sparks, flame, and
lighted cigarettes away from batteries.
WARNING! Do not allow battery fluid to contact
eyes, skin, fabrics, or painted surfaces. Always
wear eye protection. Battery acid that may spill
during charging should be washed off with a
solution of warm water and baking soda to neutralize
the acid. If you accidentally get acid in
your eyes or on your skin, immediately rinse
with cold water for several minutes and call a
doctor.
Preventive Maintenance
• Be careful that metal tools (or any metal in contact
with the positive terminal) do not contact the positive
battery terminal and any other metal on the vehicle
at the same time. Remove metal jewelry and
avoid leaning over the battery.
• If metal jewelry or other metal comes in contact with
electrical circuits, a short circuit may occur causing
you to be injured, as well as electrical system failure
and damage to the vehicle.
• Do not try to jump start or charge a frozen battery.
(Even a battery with ice particles on the electrolyte
surface is dangerous.) Allow it to thaw out first. And
always allow the battery to thaw gradually—do not
apply direct heat. Gas trapped in the ice may cause
an explosion.
To Jump Start Your Vehicle
WARNING! The voltage of the booster battery
must have a 12–volt rating. And the capacity of
the booster battery should not be lower than
that of the discharged battery. Use of batteries of
different voltage or substantially different capacity
rating may cause an explosion and serious
personal injury.
