Regular Maintenance
Figure 46. Jump Starting
WARNING
Any procedure other than the preceding could result in:
(1) personal injury caused by electrolyte squirting
out the battery vents,
(2) personal injury or property damage due to
battery explosion,
(3) damage to the charging system of the booster
vehicle or of the immobilized vehicle.
Do not attempt to jump start a vehicle having a frozen
battery because the battery may rupture or explode. If
a frozen battery is suspected, examine all fill vents on
the battery. If ice can be seen or if the electrolyte fluid
cannot be seen, do not attempt to start with jumper
cables as long as the battery remains frozen.

WARNING
For your personal safety, use extreme care when jump
starting. Never expose battery to open flame or electric
spark – battery action generates hydrogen gas which
is flammable and explosive. Do not allow battery acid
to contact skin, eyes, fabrics, or painted surfaces.
Batteries contain a sulfuric acid solution which can
cause serious personal injury or property damage.
When removing or installing battery cables, disconnect
the negative cable FIRST and reconnect it LAST. If not
done in this order, the positive terminal can be shorted
to the frame by a tool.
To avoid engine damage, do not disconnect battery
while engine is running. Be sure terminal connections
are tight before starting.
