the remote positive (+) post of the discharged
vehicle.

cable to the positive (+) post of the booster battery.

cable to the remote negative (-) post (exposed

could establish a ground connection and personal
injury could result. Do not allow the disconnected
cable ends to touch each other, or either vehicle,
until properly connected for jump starting.
Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
WARNING!
Failure to follow this jump starting procedure could
result in personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
