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.)
3. If the engine in the vehicle with the
booster battery is not running, start it
and let it run for a few minutes. During
jump starting run the engine at about
2000 rpm with the accelerator pedal
lightly depressed.
