Battery; Vehicle Storage; Jump Starting (12V System) - GMC Defense 2006 Owner's Manual Supplement

Battery

The vehicle may be equipped with deep cycle
maintenance free batteries. When it is time for a
new battery, get one that has the replacement
number shown on the original battery's label. We
®
recommend an Optima replacement battery. See
Engine Compartment Overview on page 5-4 for
battery location.
Warning: Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
Note: There is also a 12-volt battery located on
the frame under the vehicle on the passenger side.
CAUTION:
Batteries have acid that can burn you and gas that
can explode. You an be badly hurt if you are not careful.
See Jump Starting (12V System) on page 5-5 for tips
on working around a battery without getting hurt.

Vehicle Storage

If you are not going to drive your vehicle for 48 hours
or more, place the vehicle load disconnect switch in
the OFF position. See Vehicle Load Disconnect
Switch on page 2-3. This will help keep your
batteries from running down.

Jump Starting (12V System)

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.
Heavy duty jumper cables can be used to jump start
the 12-volt system.
