Hourmeter Gage
The instrument panel cluster displays the accumulated
engine run time hours using the reconfigurable
odometer VF display. The engine run time hours
displays only when the ignition is in the OFF or ACC
position and the trip reset switch is pressed for
about four seconds.
When the ignition is in the OFF or ACC position, the
instrument panel cluster displays the engine
accumulated hours for up to 30 seconds. The value of
the accumulated hours does not change when the
battery is disconnected.
The hourmeter resets to 0.0 when 10,000 hours are
accumulated. The instrument panel cluster begins
to reaccumulate the engine run time hours from 0.0
hours.
Audio System(s)
Notice:Before you add any sound equipment to
your vehicle – like a tape player, CB radio, mobile
telephone or two-way radio – be sure you can
add what you want. If you can, it’s very important to
do it properly. Added sound equipment may
interfere with the operation of your vehicle’s engine,
radio or other systems, and even damage them.Your vehicle’s systems may interfere with the
operation of sound equipment that has been added
improperly.
So, before adding sound equipment, check with
your dealer and be sure to check federal rules
covering mobile radio and telephone units.
Your audio system has been designed to operate easily
and to give years of listening pleasure. You will get
the most enjoyment out of it if you acquaint yourself with
it first. Figure out which radio you have in your vehicle,
find out what your audio system can do, and how to
operate all of its controls to be sure you are getting
the most out of the advanced engineering that went
into it.

Theft-Deterrent Feature
(Non-RDS Radios)
THEFTLOCK®is designed to discourage theft of your
radio. The feature works automatically by learning
a portion of the Vehicle Identification Number (VIN). If
the radio is moved to a different vehicle, it will not
operate and LOC will appear on the display.
With THEFTLOCK
®activated, your radio will not
operate if stolen.
Radio Reception
AM
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.
FM
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to come and go.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN to
indicate that you have used your tape player for
50 hours without resetting the tape clean timer. If this
message appears on the display, your cassette
tape player needs to be cleaned. It will still play tapes,
but you should clean it as soon as possible to
prevent damage to your tapes and player. If you notice
a reduction in sound quality, try a known good
cassette to see if the tape or the tape player is at fault.
If this other cassette has no improvement in sound
quality, clean the tape player.
For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer (GM Part No. 12344789).
