CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
Connecting The Jumper Cables
1. Connect the positive
(+)
end of the jumper cable to
the remote positive
(+)
post of the discharged
vehicle.
NOTE:
The remote positive
(+)
post is located in the engine
compartment on the driver's side under the cover of
the Front Power Distribution Center.
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 or a good engine
ground of the discharged vehicle. 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 bat-
tery and the fuel injection system.
NOTE:
The remote negative
(-)
post is located in the front of
the engine compartment on the driver's side.
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.
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 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 remote positive
(+)
post of
the discharged vehicle, and reinstall the protective
cap.
5. Close the cover of the Front Power Distribution
Center.
If frequent jump starting is required to start your vehicle
you should have the battery and charging system
inspected 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.
BATTERY LOCATION
There are two remote jump starting posts under the
hood which is the recommended jump start location. If
access to the battery is needed, an access panel on the
driver’s side floor will allow for battery access.
