Notice: If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlet. Turn off
the radio and all 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 batteries. Find the
positive (+) and negative (-) terminal locations on
each vehicle. See Engine Compartment Overview
on page 5-72 for more information on location.
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.
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@ 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.
