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.

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.

2-91
When the STABILITY SYSTEM ACTIVE message
is on, you should continue to steer in the direction you
want to go. The system is designed to help you in bad
weather or other difficult driving situations by making
the most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on,
you'll know that something has caused your vehicle to
start to spin, so you should consider slowing down.
Tire Pressure Status
- 140: If you see the TIRE
PRESSURE LOW message, you should stop as soon as
you can and check all your tires for damage. (If a tire is
flat, see ªIf a Tire Goes Flatº in the Index.) Also check
the tire pressure in all four tires as soon as you can. See
ªInflation
- Tire Pressureº and ªCheck Tire Pressure
Systemº in the Index.
There are times when you will have to reset (calibrate)
the Check Tire Pressure System. See ªCheck Tire
Pressure Systemº in the Index.
DIC Personal Choice Programming
The DIC is used to program personal choices for up to
two drivers. The drivers are recognized as DRIVER #1
and DRIVER #2. The DIC will identify a person as
UNKNOWN DRIVER if they are neither DRIVER #1
nor DRIVER #2. You will let the DIC know which
driver you are by using your remote keyless entry
transmitter or by pressing one of the MEMORY buttons
located on the driver's door. Each remote keyless entry
transmitter was pre
-programmed to belong to
DRIVER #1 or DRIVER #2. Each transmitter
may be programmed differently for each driver.
After you press the button with the unlock symbol on
your transmitter with the ignition in RUN, the DIC will
automatically display the identified driver number. The
vehicle will recall the personal choice settings that were
last made to correspond to your transmitter, including
your radio and comfort control settings. See ªComfort
Controls, Personal Choiceº in the Index.

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?

5-30
Compact Spare Tire
Although the compact spare tire was fully inflated
when your vehicle was new, it can lose air after a time.
Check the inflation pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact
spare is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full
-size tire
repaired or replaced where you want. You must calibrate
the Check Tire Pressure System after installing or
removing the compact spare. See ªCheck Tire Pressure
Systemº in the Index. Of course, it's best to replace
your spare with a full
-size tire as soon as you can.
Your spare will last longer and be in good shape
in case you need it again.
NOTICE:
When the compact spare is installed, don't take
your vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts of your vehicle.
Don't use your compact spare on other vehicles.
And don't mix your compact spare tire or wheel with
other wheels or tires. They won't fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won't fit your compact spare.
Using them can damage your vehicle and can
damage the chains too. Don't use tire chains on
your compact spare.

6-50 Check Tire Pressure System (If Equipped)
The check tire pressure system can alert you to a
large change in the pressure of one tire. The system
won't alert you before you drive that a tire is low or
flat. You must begin driving before the system will
work properly.
The TIRE PRESSURE LOW message will appear on
the Driver Information Center (DIC) if pressure
difference (low pressure) is detected in one tire. The
check tire pressure system may not alert you if:

more than one tire is low,

the vehicle is moving faster than 65 mph (105 km/h),

the system is not yet calibrated,

the tire treadwear is uneven,

the compact spare tire is installed,

tire chains are being used, or

the vehicle is being driven on a rough or frozen road.
If the anti
-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
ªAnti
-Lock Brake System Warning Lightº in the Index.The check tire pressure system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a low
tire
-- but it doesn't replace normal tire maintenance.
See ªTiresº in the Index.
When the TIRE PRESSURE LOW message appears on
the Driver Information Center, you should stop as soon
as you can and check all your tires for damage. If a tire
is flat, see ªIf a Tire Goes Flatº in the Index. Also check
the tire pressure in all four tires as soon as you can. See
ªInflation
-Tire Pressureº in the Index.
Any time you adjust a tire's pressure or have one or
more tires repaired or replaced, you'll need to reset
(calibrate) the check tire pressure system. You'll also
need to reset the system whenever you rotate the tires,
buy new tires and install or remove the compact spare.
Don't reset the check tire pressure system without first
correcting the cause of the problem and checking and
adjusting the pressure in all four tires. If you reset the
system when the tire pressures are incorrect, the check
tire pressure system will not work properly and may not
alert you when a tire is low or high.
