Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON light is on or not
working properly.
Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.
Oil Pressure Light
This light tells you if
there could be a problem
with your vehicle's engine
oil pressure.
The oil pressure light can come on briefly when you
turn your key to RUN. It goes off once you turn the key
to START. That's just a check to be sure the light works.
This is normal and doesn't show a problem. If it doesn't
come on and then go off, be sure to have it fixed so it
will be there to warn you if there is a problem.
When this light comes on and stays on, and a chime
sounds, it means oil isn't going through the engine
properly. The oil could be low, or there might be some
other oil problem. See your dealer for service.

2-85
CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered
by your warranty.
Service Vehicle Soon Light
This light will come
on if your vehicle has
certain non
-emission
related problems.
For example, if the entire electrical system fails to
send and receive messages from the vehicle's
components, the SERVICE VEHICLE SOON
warning light comes on.
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 come on briefly when the
ignition is turned on to show that it is working properly.

Instantaneous Fuel Economy: Press the FUEL INFO
button until the display shows FUEL ECONOMY INST.
Instantaneous fuel economy varies with your driving
conditions, such as acceleration, braking and the grade
of the road being traveled. The RESET button does not
function in this mode.
Average Fuel Economy: Press the FUEL INFO button
until the display shows FUEL ECONOMY AVERAGE.
Average fuel economy is viewed as a long term
approximation of your overall driving conditions. To
learn the average fuel economy from a new starting
point, press the RESET button while the average fuel
economy is displayed in the DIC.
GAGE INFO
Coolant Temperature: Press the GAGE INFO button
until COOLANT TEMP appears in the display. If there
are no problems detected with the temperature,
COOLANT TEMP NORMAL will appear in the
display. If the temperature is too high, COOLANT
TEMP HOT will appear in the display. If you see the
COOLANT TEMP HOT message, your engine is
overheated. You should pull off the road, stop your
vehicle and turn off your engine as soon as possible.
This manual explains what to do. See ªEngine
Overheatingº in the Index.Tire Pressure: Press the GAGE INFO button
until TIRE PRESSURE appears in the display.
TIRE PRESSURE NORMAL is displayed when
the Check Tire Pressure System believes your vehicle's
tire pressures are normal. If a potential tire pressure
problem is detected, the display will show TIRE
PRESSURE LOW.
Battery Volts: Press the GAGE INFO button until the
display shows BATTERY STATE. If the voltage is
normal the display will show BATTERY STATE
NORMAL. If the voltage drops below 10.5 volts, the
display will show BATTERY STATE LOW. If the
voltage is above 16 volts, the display will show
BATTERY STATE HIGH. If the display shows the high
or low message, you need to have your battery checked.
Oil Pressure: Press the GAGE INFO button until
OIL PRESSURE appears in the display. If there are no
problems detected with the oil pressure, the display will
show OIL PRESSURE NORMAL. If a low oil pressure
condition is detected, the display will show OIL
PRESSURE LOW. If you see the OIL PRESSURE
LOW message, you could be low on oil or your oil is
not going through the engine properly. See your dealer
for service.

2-90
Oil Life System: Press the GAGE INFO button until
OIL LIFE INDEX appears in the display. The OIL LIFE
INDEX NORMAL display will show an estimate of the
oil's remaining useful life. When the oil life index is less
than 10%, the display will show OIL LIFE INDEX
CHANGE OIL. When you have the oil changed, you
will have to reset the GM Oil Life System
. To reset
the Oil Life System, see ªEngine Oil Life Systemº or
ªEngine Oil, When to Changeº in the Index.
DIC Warnings and Messages
Other messages or warnings may appear in the DIC
display. For Canadian drivers, in addition to the DIC
message your DIC will display EXP with a number after
it which reflects the following messages:

messages or warnings from the DIC display.
SERVICE STABILITY SYSTEM
- 54: If you ever
see the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system (stop; turn off the engine; then start the
engine again). If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem. You
should see your dealer for service. Reduce your speed
and drive accordingly.
STABILITY SYSTEM ACTIVE
- 55: You may see
the STABILITY SYSTEM ACTIVE message on the
Driver Information Center. It means that an advanced,
computer
-controlled system has come on to help your
vehicle continue to go in the direction in which you're
steering. This stability enhancement system activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of ice or
other slippery spot on the road. When the system is on,
you may hear a noise or feel a vibration in the brake
pedal. This is normal.

4-23
Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll find experienced and able service experts in
Buick dealerships all across North America. They'll be
ready and willing to help if you need it.
Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble
-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?

4-41 When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:

start your engine,

shift into a gear, and

release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don't overfill),
engine oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the Index
will help you find them quickly. If you're trailering, it's
a good idea to review this information before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.

5-12
If the coolant inside the coolant recovery tank is boiling,
don't do anything else until it cools down. The vehicle
should be parked on a level surface.
See ªEngine Compartment Overviewº in the Index for
more information on location.The coolant level should be at or above the FULL COLD
mark. If it isn't, you may have a leak at the pressure cap or
in the radiator hoses, heater hoses, radiator, water pump
or somewhere else in the cooling system.
CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them.
If you do, you can be burned.
Don't run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fans are
running. If the engine is overheating, both fans should
be running. If they aren't, your vehicle needs service.
