In an Emergency
and remove all sources of sparks or intense heat
in the vicinity of the battery. Do not allow the ve-
hicles to touch each other. Do not lean over the
batteries when making connections, and keep all
other persons away from the batteries. Failure to
follow these precautions could lead to severe
personal injury as a result of an explosion or
acid burns.
NOTICE
Make sure both electrical systems are the same
voltage. Electronic devices on both vehicles can
be damaged when connected to a vehicle with a
different operating voltage.
1. Apply the parking brakes and turn off all lights
and other electrical devices. Ensure that the ve-
hicles are not touching and both ignition switches
are turned to the OFF position.
IMPORTANT: Do not attempt to jump start a
damaged battery.
2. Remove the battery box cover.
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.
3. Connect the positive (+) jumper cable to the
positive battery terminal or jump start post. See
Fig. 21.4.
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
21.3
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.
8. Attempt to start the engine of the vehicle receiv-
ing the jump. Do not operate the starter longer
than 30 seconds, and wait at least two minutes
between starting attempts to allow the starter to
cool.
9.
When the engine starts, let it idle a few minutes.
10. Disconnect the negative jumper cable from the
negative cable stud on the jump started vehicle.
11. Disconnect the negative jumper cable from the
booster battery.
12.
Disconnect the positive cable from the booster
battery.
13. Disconnect the other end of the positive jumper
cable from the jump started vehicle.
14. Install the battery box cover; be sure it is posi-
tioned properly before fastening the latch.
Towing
When it is necessary to tow the vehicle, make sure
the instructions below are closely followed to prevent
damage to the vehicle.
WARNING
Do not tow an unbraked vehicle if the combined
weight of both vehicles is more than the sum of
the gross axle weight ratings (GAWR) of the tow-
ing vehicle. Otherwise brake capacity will be in-
adequate, which could result in personal injury or
death.
