Pontiac 2007 G5 Owner's Manual page 305

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 hood on the other vehicle and
locate the positive (+) and negative ( )
terminal locations on that vehicle.
You will not see the battery of your vehicle
under the hood. It is located in the trunk. You
will not need to access your battery for jump
starting. Your vehicle has a remote positive (+)
and a remote negative ( ) jump starting
terminal.
The remote positive
terminal is located
under a red tethered
cap on the engine
compartment fuse block.
Lift the cap to access
the terminal.
