Chevrolet 2003 Tahoe Owner's Manual page 399

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 behind a
red plastic cover 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 on all V8 and diesel
engines, and on the thermostat housing on the
8.1 L engine. On V8 engines it is marked "GND."

l g a mat near a battery can causc attery
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
don't need to add water to the ACDelco@
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.
Don't 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.
