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 of the discharged vehicle.
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. Only use the specific
ground point, do not use any other exposed
metal parts.
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, disconnect the
jumper cables in the reverse sequence:
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 nega-
tive (-) 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 posi-
tive (+) jumper cable from the remote
positive (+) post of the discharged
vehicle.
5. Close the cover of the Front Power Distri-
bution Center.
If frequent jump starting is required to start
your vehicle you should have the battery and
charging system inspected at your authorized
dealer.
CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle'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 dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
