Pontiac 2005 GTO - Manual (Page 227)

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. 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. See Engine Compartment Overview
on page 5-12 for more information on location.
{ CAUTION:
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.
{ CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
flashlight if you need more light. Be sure the
battery has enough water. You do not need to
add water to the battery installed in your new
vehicle. But if a battery has filler caps, be sure
the right amount of fluid is there. If it is low,
add water to take care of that first. If you don’t,
explosive gas could be present.
Battery fluid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, flush the place
with water and get medical help immediately.
