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.
Bulb Replacement
In this section you'll find directions for changing
the bulbs in some of the lamps on your Buick.
See
"Replacement Bulbs" in the Index to find the type
of bulb you should use.
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See "Jump Starting" in the Index
for tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see "Theft-Deterrent
Feature" in the Index.
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
