Connecting The Jumper Cables
1. Connect the positive (+) end of the jumper cable to
the 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.
Jump Starting Label
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.
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
2,000 RPM since it provides no charging benefit,
wastes fuel, and can damage booster vehicle engine.
6. Once the engine is started, follow the disconnecting
procedure.
IN CASE OF EMERGENCY
Disconnecting The Jumper Cables
1. Disconnect the negative (-) end of the jumper cable
from the engine ground of the vehicle with the
discharged battery.
2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the booster
battery.
3. Disconnect the positive (+) end of the jumper cable
from the positive (+) post of the booster battery.
4. Disconnect the opposite end of the positive (+)
jumper cable from the positive (+) post of the
discharged vehicle.
5. Reinstall the protective cover over the positive (+)
post of the discharged vehicle.
If frequent jump starting is required to start your vehicle
you should have the battery and charging system tested at
an authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets draw
power from the vehicle's battery, even when not in use
(i.e., cellular devices, etc.). Eventually, if plugged in long
enough without engine operation, the vehicle's battery
will discharge sufficiently to degrade battery life and/or
prevent the engine from starting.
