Jump Starting - GMC 2004 Defense Owner's Manual

Jump Starting

If the battery (or batteries) on the vehicle have run down
and the vehicle will not start, you may want to use
another vehicle to provide power to start the vehicle.
NATO slave cables are the only recommended method
for 24-volt jump starting of the vehicle. You should only
use NATO slave cables to jump start similar vehicles.
Heavy duty jumper cables can be used to jump start the
12-volt system. See Jump Starting from a 12-volt System.

CAUTION:
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.
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.
