Pontiac Montana SV6 2008 Owner's Manual page 338

Notice: If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet. Turn off
the radio and all lamps that are not needed. This will
avoid sparks and help save both batteries. And it
could save the radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (−) terminal locations on
each vehicle.
You will not need to access your battery for jump
starting. Your vehicle has a remote positive (+) jump
starting terminal for that purpose.

See Engine Compartment Overview on page 5-12
for more information on the location of the
remote positive (+) terminal. You should always
use the remote positive (+) terminal instead of the
positive (+) terminal on your battery.

Keep hands, clothing and tools away from
any underhood electric fan.
The terminal is located
under the fuse block cover.
Remove the cover to
access the remote
positive (+) terminal.
