356 IN CASE OF EMERGENCY
Connecting The Jumper Cables
1. Connect the positive
(+) end of the jumper
cable to the positive
(+)
post of the discharged
vehicle.
NOTE:
Do not jump off fuses. Only jump directly off
positive post.
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, follow the
disconnecting procedure below.
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
vehicle with the discharged battery.
If frequent jump starting is required to start your
vehicle you should have the battery and charging
system inspected at an authorized dealer.
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.
CAUTION!
Do not connect jumper cable to any of the fuses
on the positive battery terminal. The resulting
electrical current will blow the fuse.
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.
