Jump Starting Procedure
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.
NOTE:
Make sure at all times that unused ends of jumper
cables are not contacting each other or either vehicle while
making connections.
Connecting The Jumper Cables
1. Connect the positive
(+)
end of the jumper cable to the
remote positive
(+)
post of the discharged vehicle.
2. Connect the opposite end of the positive
(+)
jumper
cable to the positive
(+)
post of the booster battery.
3. Connect the negative end
(-)
of the jumper cable to the
negative
(-)
post of the booster battery.
4. Connect the opposite end of the negative
(-)
jumper
cable to a good engine ground (exposed metal part of
the discharged vehicle’s engine) away from the battery
and the fuel injection system.
WARNING!
Do not connect the jumper cable to the negative (-) post
of the discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury. Only use the specific ground point, do
not use any other exposed metal parts.
5. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
CAUTION!
Do not run the booster vehicle engine above 2000 rpm
since it provides no charging benefit, wastes fuel and
can damage booster vehicle engine.
6. Once the engine is started, remove the jumper cables in
the reverse sequence:
