Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your
GM dealer before adding equipment to the outside
of your vehicle.
Fuel (Gasoline Engine)
If your vehicle has a diesel engine, see “Diesel Fuel
Requirements and Fuel System” in the Diesel Engine
Supplement. For vehicles with gasoline engines, please
read this.
Use regular unleaded gasoline rated at 87 octane or
higher. At a minimum, it should meet specifications
ASTM
D48 14 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability and
emission control system protection compared to
other gasolines. Be
sure the posted octane is at least 87. If the octane
is
less than 87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
hear heavy knocking, your engine needs service.
But
don’t worry if you hear a little pinging noise when
you’re accelerating or driving up a hill. That’s normal,
and
you don’t have to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it
is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test. If this occurs, return to your
authorized
GM dealer for diagnosis to determine the
cause of failure.
In the event it is determined that the
cause of the condition is the type
of fuels used, repairs
may not be covered by your warranty.

Every new vehicle 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 replacement 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.
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.
Bulb Replacement
Before you replace any bulbs, be sure that all the lamps
are
off and the engine isn’t running. See “Replacement
Bulbs”
in the index for the proper types of bulbs to use.
Halogen Bulbs
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.
