5. Find the positive (+) and negative ( - ) terminals on
each battery or remote terminal. You should always
use the remote positive (+) terminal instead of the
positive (+) terminal on your battery.
To open the remote positive (+) terminal box, pull
the tab and open the cover.
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 don’t need
to add water to the ACDelco Freedom
R
battery
installed in every new GM 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.
6. Check that the jumper cables don’t have loose or
missing insulation. If they do, you could get a shock.
The vehicles could be damaged too.
Before you connect the cables, here are some things
you should know. Positive (+) will go to positive (+)
and negative (
- ) will go to a metal engine part. Don’t
connect positive (+) to negative ( - ) or you’ll get a
short that would damage the battery and maybe other
parts too.
CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
