Programming the Universal Transmitter
Do not use the Universal Transmitter with any garage
door opener that does not have the ªstop and reverseº
safety feature. This includes any garage door opener
model manufactured before April 1, 1982.Be sure that people and objects are clear of the garage
door you are programming.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the Universal Transmitter
until the indicator light begins to flash rapidly (after
20 seconds). Then release the buttons. This
procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want to
program. Hold the end of the hand
-held transmitter
about 2 to 5 inches (5 to 13 cm) away from the
surface of the Universal Transmitter so that you can
still see the indicator light.
3. Using both hands, press the hand
-held transmitter button
and the desired button on the Universal Transmitter.
Continue to press both buttons through Step 4.

The traction control system warning light may come on
for the following reasons:

If you turn the system off by pressing the button
located on the end of the gearshift lever, the warning
light will come on and stay on. To turn the system
back on, press the button again. The warning light
should go off. (See ªTraction Control Systemº in the
Index for more information.)

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into
the red area, your engine
is too hot!
A temperature indicator light will come on and a
chime will sound.
If you have been operating your vehicle under normal
driving conditions and the temperature indicator light
turns on, you should pull off the road, stop your vehicle
and turn off the engine as soon as possible.
The ªProblems on the Road,º section of this manual
explains what to do. See ªEngine Overheatingº in
the Index.

2-72 Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to assure
that emissions are at acceptable levels for the life of the
vehicle, helping to produce a cleaner environment. The
SERVICE ENGINE SOON light comes on and a chime
will sound to indicate that there is a problem and service is
required. Malfunctions often will be indicated by the
system before any problem is apparent. This may prevent
more serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transaxle,
exhaust or fuel system of your vehicle or the
replacement of the original tires with other than
those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.

2-76 Service Vehicle Soon Light
This light will come on and
stay on if you have certain
non
-emission related
vehicle problems.
These problems may not be obvious and may affect vehicle
performance or durability. Consult a qualified dealership for
necessary repairs to maintain top vehicle performance.
This light will also come on briefly when your ignition
is turned on to show that the system is working properly.
Cruise Light
The cruise light comes on
whenever you set your
cruise control. See ªCruise
Controlº in the Index.
Fuel Gage
Standard Cluster Gage Cluster
Your fuel gage shows about how much fuel is in your
tank. It works only when the engine is on. When the
indicator nears the edge of the low fuel warning band,
the low fuel light will turn on and a chime will sound.
You still have a little fuel left, however you need to
refuel right away.

Here are some things that some owners ask about.
None of these show a problem with your fuel gage:

At the service station, the gas pump shuts off before
the gage reads FULL (F).

It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank's capacity to
fill the tank.

The gage moves a little when you turn a corner,
speed up, or make a hard stop.

The gage doesn't go back to EMPTY (E) when you
turn off the ignition.Head-Up Display (HUD)
(If Equipped)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument cluster.
The information may be displayed in English or metric
units and appears as a reflection in the windshield. The
HUD consists of the following information:

3-38 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 dealership (GM Part No. 12344789).When using a scrubbing action, non
-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape.
If the cleaning cassette ejects, insert the cassette at least
three times to ensure thorough cleaning.
You may also choose a non
-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non
-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non
-scrubbing action, dry-type cleaning
cassette is not recommended.
After you clean the player, press and hold EJECT for
five seconds to reset the CLN indicator. The radio will
display
--- to show the indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
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. (See ªMalfunction
Indicator Lampº in the Index.) If this occurs, return to
your authorized Buick 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.
Some gasolines that are not reformulated for low
emissions may contain an octane
-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask your service station operator whether or not
the fuel contains MMT. General Motors does not
recommend the use of such gasolines. If fuels containing
MMT are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on. If this occurs, return to your
authorized Buick dealer for service.To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
contribute to clean air. General Motors recommends that
you use these gasolines, particularly if they comply with
the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don't use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn't
be covered under your warranty.

6-29 Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built
-in wear indicators that make a
high
-pitched warning sound when the brake pads are worn
and new pads are needed. The sound may come and go or
be heard all the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in the
proper sequence to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See ªBrake System Inspectionº in Section 7 of this manual
under Part C ªPeriodic Maintenance Inspections.º
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
