Chevrolet Impala 2007 Impala Owner's Manual page 342

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 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. The remote positive (+) terminal
is located in the engine compartment on
the passenger's side of the vehicle, on the
underhood fuse block. See Engine
Compartment Overview on page 308 for
more information on location.

{
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
To uncover the remote
positive (+) terminal,
remove the fuse
block cover. You should
always use the
remote positive (+)
terminal instead of the
positive (+) terminal
on the battery.
