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 the remote negative (-) post
(exposed metallic/unpainted post of the
discharge vehicle) located on the right hand
side next to the under-hood fuse box.
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 below.
Disconnecting The Jumper Cables
1. Disconnect the negative (-) end of the
jumper cable from the remote negative (-)
post of the discharged vehicle.
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.
IN CASE OF EMERGENCY
4. Disconnect the opposite end of the
positive (+) jumper cable from the remote
positive (+) post of the discharged vehicle.
5. Reinstall the protective cover over the
remote positive (+) post of the discharged
vehicle.
If frequent jump starting is required to start your
vehicle 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.
