GMC T-Series 2007, Owner'S Manual

Page: 237 / 356

To avoid the possibility of the vehicles rolling,
set the parking brake firmly on both vehicles
involved in the jump start procedure. Put
an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brake.
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 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. Locate the batteries on each vehicle. Find the
positive (+) and negative (
−
) terminals on each
battery.
You will not see the batteries of your vehicle
under the hood. They are located in a frame
mounted battery box on the passenger’s side of
the vehicle.
{
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 batteries have enough water.
You do not need to add water to the
ACDelco
®
battery (or batteries) 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 do not, 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.
