Buick 2007 LaCrosse Owner's Manual page 386

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
outlets. 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 use your vehicle's battery for jump
starting. It has a remote positive (+) jump
starting terminal, located on the underhood
fuse block, for that purpose. See Engine
Compartment Overview on page 350 for more
information on location.

Keep hands, clothing and tools away from
any underhood electric fan.

positive (+) terminal,
