any other metal on the vehicle at the same
time. Remove metal jewelry; avoid leaning
over a battery. If metal jewelry or other
metal comes in contact with electrical cir

cuits, a short circuit may occur causing you
to be injured—plus 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 battery
to thaw gradually—do not apply direct heat.
Gas trapped in the ice may cause an explo

sion.
• Do not try to jump start a vehicle if the elec-
trolyte level in the battery of either vehicle is
low. Maintain the full level of electrolyte in
the batteries. This reduces the volume of
gas in the cells.
• 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 substan
-
tially different capacity rating may cause an
explosion. To avoid serious personal injury
and damage to the vehicle, heed all warn
-
ings and instructions of the jumper cable
manufacturer. The jumper cables must be
long enough so that the vehicles do not
touch.
• Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as relays, and
the radio. Improper hook–up of jumper
cables or not following these procedures
can damage the alternator or cause serious
damage to both vehicles or yourself.
• Battery posts, terminals, and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
• To avoid serious personal injury and dam-
age to the vehicle, heed all warnings and
instructions of the jumper cable manufac
