IMPORTANT: Do not attempt to jump start a
damaged battery.
2.
Remove the battery box cover. See Fig. 24.4 for
the standard battery compartment location.
NOTICE
Always connect the batteries and jumper cables
correctly (positive-to-positive and negative-to-
negative). Connecting a charging device back-
wards (positive-to-negative) can severely damage
the vehicle electrical content and cause non-
warrantable failures.
IMPORTANT: On vehicles equipped with op-
tional jump start posts, connect to these posts
instead of the battery terminals. Jump start
posts may be installed in various locations on
the vehicle. See
Fig. 24.5.
3.
Connect the positive (+) jumper cable to the
positive terminal or jump start post on the dis-
charged battery. See
Fig. 24.6.
4.
Connect the other end of the positive jumper
cable to the positive terminal or jump start post
on the booster battery providing the charge.
WARNING
Do the next step exactly as instructed and do not
allow the clamps of one cable to touch the
clamps of the other cable. Otherwise, a spark
could occur near a battery, possibly resulting in
severe personal injury from explosion or acid
burns.
5.
Connect the negative (-) jumper cable to the
negative terminal or jump start post on the
booster battery.
6.
Connect the other end of the negative jumper
cable to the negative ground stud on the vehicle
requiring the jump start.
7.
Start the engine of the vehicle providing the jump
start and let the engine run a few minutes to
charge the batteries of the other vehicle.
