JUMP STARTING PROCEDURE

1.

If the booster battery is installed in

another vehicle, make sure the vehicles

are not touching. Turn off all unneces-

sary lights and accessories.

2.

If required, remove all the vent plugs

from the booster and discharged batter-

ies. Lay a cloth over the open vents

on the batteries. (This helps reduce the

explosion hazard, personal injuries and

burns.)
