J S P
UMP TARTING ROCEDURE
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 the remote negative (-) post (exposed
metallic/unpainted post of the discharge vehicle)
located directly in front of the underhood 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.
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.
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.
