Jump starting can be dangerous if
done incorrectly. Follow the jump

strongly recommend that you have a
service technician or towing service

Batteries contain sulfu-
ric acid which is highly
corrosive. Do not allow
acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical attention immediately.
•When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak. Lift with a battery
carrier or with your hands on
opposite corners.
•Do not attempt to jump start
your vehicle if your battery is
frozen.
(Continued)
To prevent SERIOUS INJURY or
DEATH to you or bystanders,
always follow these precautions
when working near or handling
the battery:
Always read and follow
instructions carefully
when handling a battery.
Wear eye protection
designed to protect the
eyes from acid splashes.
Keep all flames, sparks,
or smoking materials
away from the battery.
Hydrogen is always pres-
ent in battery cells, is
highly combustible, and
may explode if ignited.
Keep batteries out of
reach of children.
