354 IN CASE OF EMERGENCY
JUMP STARTING PROCEDURE
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. A
“ground” is an exposed metallic/unpainted
part of the engine, frame or chassis, such as
an accessory bracket or large bolt. The
ground must be away from the battery and
the fuel injection system.
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.
6. Once the engine is started, remove the
jumper cables in the reverse sequence.
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!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
WARNING! (Continued)
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged vehicle.
WARNING!
Do not connect the jumper cable to the nega-
tive (-) post of the discharged battery. The
resulting electrical spark could cause the bat-
tery to explode and could result in personal
injury.
CAUTION!
Do not run the booster vehicle engine above
2,000 RPM since it provides no charging ben-
efit, wastes fuel, and can damage booster
vehicle engine.
