1. Check the other vehicle. It must have a 12-volt
battery with a negative ground.
Getting between vehicles that are being jump
started is dangerous. If the vehicles were to
move you could be seriously injured or killed.
Do not stand in front of the vehicle being jump
started. Never jump start frozen batteries they
can explode. You or others can be could be
seriously injured. Allow the battery to thaw at
room temperature before jump starting.
CAUTION:
Notice: Ignoring these steps could result in costly
damage to the vehicle that would not be covered by the
vehicle warranty. Trying to start the vehicle by pushing
or pulling it will not work, and it could damage the vehicle.
2. Get the vehicles close enough so that jumper
cables can reach, but be sure the vehicles are
not touching each other. If they are, it could cause
a ground causing the vehicle not to start. The bad
grounding could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put the automatic
transmission in PARK (P). Be sure the transfer
case is in a drive gear and is NOT in NEUTRAL
(N).
Batteries can hurt you. They can be dangerous
because:
•
They contain acid that can burn you.
•
They contain gas that can explode or ignite.
•
They contain enough electricity to burn you.
If you do not follow these steps exactly, some
or all of these things can hurt you.
CAUTION:
Notice: If you leave the communications/navigation
equipment or other accessories on during jump
starting procedure, they could be damaged. The
repairs wouldn’t be covered by the warranty.
Always turn off your communications/navigation
equipment or other accessories when jump starting
your vehicle.
