GMC Denali 2004 Owner's Manual page 334

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 in the accessory power outlets. Turn off
the radio and all the lamps that aren't needed. This
will avoid sparks and help save both batteries.
And it could save your radio!
4. Open the hoods and locate the positive (+) and
negative (−) terminal locations of the other vehicle.
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (−) jump
starting terminal. You should always use these
remote terminals instead of the terminals on the
battery.
The remote positive (+) terminal is located near
the engine accessory drive bracket. To uncover the
remote positive (+) terminal, open the red plastic
cover.
The remote negative (−) terminal is located on the
engine drive bracket and it is marked "GND."
See Engine Compartment Overview on page 5-10
for more information on location.

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 ACDelco
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.
