Malfunction Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE
SOON
Your Buick is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system
is called OBD I1 (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. (In Canada,
OBD I1 is replaced by
Enhanced Diagnostics.) 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.
1 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.
This light should come on, as a check to show you it is
working, when the ignition is
on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during
a malfunction in one
of
two ways:
0 Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
0 Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

To find your comfort setting, start with the system in
AUTO mode and the
TEMP button adjusted to a display
of
75 OF (24"C), give the vehicle about 20 minutes to
stabilize, and adjust your comfort setting if necessary, by
using the TEMP button. The display will show the
comfort setting, fan speed and airflow direction for a few
seconds, and then it will display the outside temperature.
In cold weather, the system will delay turning the fan on
high, to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Pushing the FAN, AIR FLOW
or FRONT buttons will override this delay, turn
off the
AUTO setting and change the fan speed.
Manual Operation
You may also manually adjust the air delivery or fan speed.
AIR FLOW This button is used to change the direction
of the aifflow. The airflow choices available are FLOOR,
FLOOR-MID,
MID and WINDSHIELD-FLOOR. If the
system is set
for AUTO, pressing the AIR FLOW button
will display the current airflow direction, the comfort
setting and the fan speed. Press the AIR FLOW up or
down button again
to change the direction of the airflow.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the mid-position.
If the AIR FLOW down button is
selected while
in the FRONT defrost mode, the system
will direct the air toward the
FLOOR, and the FRONT
defrost mode will cancel. Notice the arrows in the display.
OFF: If the passenger comfort control is turned on, it
can be turned
off by pressing the OFF button once.
Pressing the OFF button a second time will turn
off the
main system. Turning
off the main system causes the fan
to turn off and the airflow to be directed to the FLOOR.
The system will still try to keep the interior of the
vehicle at the previous chosen comfort setting. The
outside temperature will show on the display when the
system is off.
The ventilation system always allows fresh air to flow
through your Buick when the vehicle is moving even
with the system in the OFF mode.
VENT: The VENT button allows outside air to flow
through your Buick without the air conditioning
compressor working. Selecting VENT and the AUTO
button at the same time allows the system to control
automatically without
the use of the air conditioning
compressor or the
use of the RECIRC mode. To turn
off the VENT selection, push the VENT button again.

RECIRC: When RECIRC is selected, the system will
limit the amount of outside air entering your vehicle.
This is helpful when you
are trying to cool the interior
of the vehicle quickly or limit the amount of outside air
entering your vehicle for some other reason. RECIRC
and AUTO may be selected at the same time. The
system will remain in RECIRC until the ignition is
turned
off. The system will return back to the previously
selected mode when the car is turned back on. RECIRC
can be selected in all manual airflow modes except
FRONT defrost. RECIRC cannot be selected with the
VENT button.
FRONT This selection is used to defrost the
windshield by directing the airflow toward the windshield.
If FRONT is selected while in the AUTO mode, the fan
speed and the
air temperature from the front defroster will
vary.
If a manual fan speed setting is selected, the fan
speed will remain
at that selection until another fan speed
selection is made or the AUTO mode is selected. To turn
off FRONT, press the AUTO or AIR FLOW button.
FRONT defrost will work better if any
ice or snow is
cleared from the hood and the air inlet area between the
base of the windshield and the hood.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle
to cool down. Then keep your windows closed
for the air conditioner to work its best.
On very hot days, the system will automatically enter
the RECIRC mode and the temperature door will be
positioned at the full cold position for maximum
cooling. If the system is not in the AUTO mode,
RECIRC should be selected to provide maximum
cooling.
You can choose the extreme comfort setting of
60°F (16"C), but the system will not cool any faster
by choosing the extreme comfort setting.
Heating
Press AUTO and adjust the temperature by pressing the
TEMP up or down arrow. You may also adjust the dual
automatic comfortemp system manually by pressing the
AIR FLOW button until FLOOR appears. Again, adjust
the temperature by pressing the TEMP up or down arrow.
Outside air will be brought in and sent through the
floor outlets. The heater works best if you keep your
windows closed.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for
a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (0)
or THIRD (3).
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops.
But then, if you still have the
warning,
turn ofthe engine and get everyone out of the
vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.

If you have the 3800 Supercharged engine (VIN Code
l), use premium unleaded gasoline rated at 91 octane or
higher. With the
3800 Supercharged engine, in an
emergency, you may be able to use a lower octane
-- as
low as
87 -- if heavy knocking does not occur. If you
are using 91 or higher octane unleaded gasoline and you
hear heavy knocking, your engine needs service.
At a minimum, the gasoline you use should meet
specifications ASTM D4814 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 for premium is at least 91 (at
least 89 for middle grade and
87 for regular). 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 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 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 contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not his 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.

Your Park Avenue Ultra has a 3800 Supercharged
engine. Buick chose supercharging rather than
turbocharging because Buick emphasizes smooth,
refined power.
The supercharger
is a device which is designed to pump
more air into the engine than it would normally use.
This air mixed with fuel creates increased engine power.
Since the supercharger is a pump and is driven from an
engine accessory drive belt, increased pressure is
available at all driving conditions.
The Powertrain Control Module (PCM) works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this increased pressure or boost is not desired, such as during
idling and light throttle cruising, the excess air that the
supercharger is pumping is routed through a bypass. All
of these controls working together provide high
performance character and fuel efficiency in the
3800
V6 Supercharged Buick engine.
The power steering pump and reservoir are mounted on
the rear (driver’s side) of the engine block. See
“Maintenance Schedule” in the Index for when you
should check the fluid.
Engine Oil
3 \
c
.
If you have the Driver Information Center, an ENGINE
OIL LOW-CHECK LEVEL message will appear when
the engine oil is approximately
1 quart (IL) low. If the
message is displayed, check the dipstick level and add
oil as needed.

Temperature -- A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade
C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
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.
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.
Scheduled wheel alignment and wheel balancing are not
needed. 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
Buick dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
ProCarManuals.com

Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody.
If these are not
removed, accelerated corrosion (rust) can occur on the
underbody parts such as fuel lines, frame, floor pan and
exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can
do
this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can falhpon and
attack painted surfaces on your vehicle. This damage
can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect in the paint job causes this, Buick
will repair, at no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.
