Every new Oldsmobile has a Delco
Freedom@ battery. You never have to
add water to one of these. When it’s
time for a new battery,,+we recommend a
Delco Freedom@ battery. Get one that
has the catalog number shown on the
original battery’s label.

Vehicle Storage
If you’re not going to drive your vehicle
for
25 days or more, take off the black
negative
(-) cable from the battery. This
will help keep your battery
from
running down. In
this section you’ll find directions for
changing the light bulbs in some of the
lights on your Oldsmobile. You’ll also
find directions for adjusting the
alignment of the mini-quad headlights,
if you have this type.
Be sure to read the directions before
you begin to replace or adjust any lights
See the
Index under Replacement
Bulbs to find the type of bulb you need
to use.
Batteries have acid that can
burn you and gas that can
explode. You can be badly hurt
if
you aren’t careful. See the Index
under Jump Starting for tips on
working around a battery without
getting hurt.
Contact your deakr to
learn how to
