or the factory back-up code, and the unit is in the UNSECURED
mode.
If the display shows “SEC”, the disabling sequence was
unsuccessful and the numbers did not match either of the codes and the
unit will remain
in the SECURED mode.
Understanding Radio Reception
FM stereo will give you the best sound. But FM signals will reach only
about 10 to
40 miles (16 to 65 km). And, tall buildings or hills can interfere
with
FM signals, causing the sound to come and go.
The range for most AM stations is greater than for
FM, especially at night.
The longer range, however, can cause stations to interfere with each other.
AM can pick up noise from things like storms and power lines. Try reducing
the treble to reduce this noise if you ever get it.
AM Stereo means the Delco@ system can receive C-QUAM@stereo
broadcasts. Many AM stations around the count use C-QUAM@ to
produce stereo, though some do not. (C-QUAM is a registered trademark
of Motorola, Inc.) If your Delco@ system can get C-QUAM@, your
“STEREO” light will come on when you’re receiving
it.
Be aware that hearing damage from loud noise is almost undetectable until
it is too late. Your hearing can adapt to higher volumes
of sound. Sound that
seems normal can be loud and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe sound level before your
hearing adapts to it.

To help avoid hearing loss or damage:
1. Adjust the volume control to the lowest setting.
2. Increase volume slowly until you hear comfortably and clearly.

your radiator pressure

Thermostat
Engine coolant temperature is controlled by a thermostat in the engine
coolant system. The thermostat stops the
flow of coolant through the
radiator until the coolant reaches
a preset temperature.
When
you replace your thermostat, an AC@ thermostat is recommended.

Downloaded from www.Manualslib.com manuals search engine Warning: The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination, can cause heat
buildup and possible tire failure.
These grades are molded on the sidewalls of passenger
car tires.
While the tires available as standard or optional equipment on General
Motors vehicles may vary with respect to these grades, all such tires meet
General Motors performance standards and have been approved for use on
General Motors vehicles. All passenger type
(P Metric) tires must conform
to Federal safety requirements in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tire life and best overall performance.
In most cases, you will not need to have your wheels aligned again.
However, if you notice unusual tire wear or your vehicle pulling one way or
the other, the alignment may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels may need to be
rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted or corroded. If
wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your GM dealer if any of
these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load carrying capacity, diameter,
width, offset, and be mounted the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts, or wheel nuts,
replace them only with new GM original equipment parts. This way, you
will be sure to have the right wheel, wheel bolts, and wheel nuts for your
vehicle.
