Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise switch to ON.
2. Get up to the speed you want.
3. Press in the SET button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts off
the cruise control. But you don't need to reset it.Once you're going about 25 mph (40 km/h) or more,
you can move the cruise switch from ON to R/A
(Resume/Accelerate) briefly.
You'll go right back up to your chosen speed and
stay there.
Remember, if you hold the switch at R/A longer, the
vehicle will keep going faster until you release the
switch or apply the brake. So unless you want to go
faster, don't hold the switch at R/A.
Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:

Use the accelerator pedal to get to the higher speed.
Press the SET button at the end of the lever, then
release the button and the accelerator pedal. You'll
now cruise at the higher speed.

Move the cruise switch from ON to R/A. Hold it
there until you get up to the speed you want, and
then release the switch. (To increase your speed in
very small amounts, move the switch to R/A briefly.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.)

2-51 Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). Your
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
Tamper
-Resistant Odometer
Your odometer is tamper
-resistant. The odometer will
show silver lines between the numbers if someone tries
to turn it back.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new odometer can be set
to the mileage total of the old odometer, then it must be.
But if it can't, then it's set at zero, and a label must be
put on the driver's door to show the old mileage reading
when the new odometer was installed.Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
To reset the trip odometer, fully press the reset button
located near the trip odometer readout. If the reset
button is not fully pressed, the trip odometer may not go
all the way back to zero. If it doesn't, you may have to
press the reset button again to reset the readout to zero.Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
NOTICE:
On vehicles with a manual transmission, if you
operate the engine with the tachometer in the red
area, your engine or other parts could be damaged.
Damage to your engine or vehicle caused by
operating the engine in the red area isn't covered
by your vehicle warranty. Don't operate the
engine with the tachometer in the red area.

3-25 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 it is the tape or the tape
player at fault. If this other cassette has no improvement
in sound quality, clean the tape player.
The recommended cleaning method for your
cassette tape player is the use of 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).When cleaning the cassette tape player with the
recommended non
-abrasive cleaning cassette, it is
possible that the cassette may eject, because the cut
tape detection feature on your radio may recognize it
as a broken tape. To prevent the cleaning cassette from
being ejected, use the following steps.
If your vehicle is equipped with the AM
-FM Stereo
with Cassette Tape Player do the following:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio on.
3. Insert the scrubbing action cleaning cassette.
4. Within five seconds, press and hold the REV and
FWD buttons at the same time for three seconds.
The tape symbol will flash on the display, showing
that the cut tape detection feature is no longer active.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
If your vehicle is equipped with the AM
-FM Stereo
with Cassette Tape Player and Automatic Tone Control
do the following:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
