2000 BUICK CENTURY warning

2-53 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 in kilometers
(used in Canada).
Your vehicle has a tamper
-resistant odometer. If you see
ERROR, you'll know someone has probably tampered
with it and the numbers may not be accurate.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
But if it can't, then it will be 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
Your trip odometer tells how far you have driven since
you last reset it. To set it to zero, press the button on the
right side of the instrument cluster.
Your trip/select reset switch will go back and forth
between the odometer and the trip odometer if the button
is pressed and released within 1.5 seconds. If the button is
pressed and held for longer than 1.5 seconds while in the
trip odometer mode, it will be reset to zero. If the button is
pressed and held for longer than 1.5 seconds while in the
odometer mode, it will have no effect.
Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.

2-54
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds, then
it will flash for about
55 seconds.
If the driver's belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag's electrical system for malfunctions.
The light tells you if there is an electrical problem. The
system check includes the air bag modules, the wiring
and the crash sensing and diagnostic module. For more
information on the air bag system, see ªAir Bagº in
the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.

2-56 Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
United States Canada
This light should come on briefly when you turn the
ignition key to RUN. If it doesn't come on then,
have it fixed so it will be ready to warn you if there's
a problem.If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. (See ªTowing Your Vehicleº
in the Index.)
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake doesn't release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.

2-57 Anti-Lock Brake System Warning Light
United States Canada
The anti
-lock brake system warning light should come on
for a few seconds when you turn the ignition key to RUN.
If the anti
-lock brake system warning light stays on longer
than normal after you've started your engine, turn the
ignition off. Or, if the light comes on and stays on when
you're driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again while
you're driving, the anti
-lock brake system needs service
and you don't have anti
-lock brakes. The brake pedal may
be harder to push, or it may go to the floor. It may take
longer to stop. Adjust your driving accordingly.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Enhanced Traction System Warning Light
(3100 V6 Engine)
The Enhanced Traction System warning light may come
on for the following reasons:

If you turn the system off by shifting to
SECOND (2) or FIRST (1), the warning light will
come on and stay on. To turn the system back on,
shift to THIRD (3) or AUTOMATIC
OVERDRIVE (
). See ªEnhanced Traction
Systemº in the Index.

If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. Adjust your driving accordingly.

2-58

The warning light will come on when you set your
parking brake with the engine running, and it will
stay on if your parking brake doesn't release fully.
If the transaxle shift lever is in any position other
than FIRST (1) or SECOND (2) and the warning
light stays on after your parking brake is fully
released, it means there's a problem with the system.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
Enhanced Traction System Active Light
The light will come on when your Enhanced Traction
System is limiting wheel spin. You may feel or hear the
system working, but this is normal. Slippery road
conditions may exist if this light comes on, so adjust
your driving accordingly.
Low Traction Light
If you have the Enhanced Traction System, this light
will also come on when the system is limiting wheel
spin. You may feel or hear the system working, but this
is normal. Slippery road conditions may exist if the
low traction light comes on, so adjust your driving
accordingly. The light will stay on for a few seconds
after the Enhanced Traction System stops limiting wheel
spin. See ªEnhanced Traction Systemº in the Index.
The low traction light also comes on briefly when you
turn the ignition key to RUN. If the light doesn't come
on then, have it fixed so it will be there to tell you when
the Enhanced Traction System is active.

2-59 Engine Coolant Temperature Light
This light tells you that
your engine coolant has
overheated or your radiator
cooling fan is not working.
The light will come on briefly when your ignition is
turned on to show you that it is working.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Engine Coolant Temperature Gage
You have a gage that
shows the engine
coolant temperature.
If the gage pointer
moves into the red
area, your engine is
too hot!
That reading means the same thing as the warning light.
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.

2-60 Low Coolant Warning Light
If the LOW COOLANT light comes on, your system is
low on coolant and the engine may overheat. See
ªEngine Coolantº in the Index and have your vehicle
serviced as soon as you can.
The light will come on
briefly when your ignition
is turned on to show you
that it is working properly.
Low Tire Light
The low tire inflation
monitor system can
alert you to a large
change in the pressure
in one tire.
After the system has ªlearnedº tire pressures with
properly inflated tires, the LOW TIRE light will come
on if the pressure in one tire becomes 12 psi (83 kPa)
lower than the other three tires. The low tire inflation
monitor system won't alert you if the pressure in more
than one tire is low, if the system is not yet calibrated, or
if the vehicle is moving faster than 70 mph (110 km/h).
When the LOW TIRE light comes on, 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.
The light will stay on until you turn off the ignition or
reset the system. See ªLow Tire Inflation Monitor
Systemº in the Index.

2-64 Low Oil Pressure Warning Light
If you have a problem with
your oil, this light may stay
on after you start your
engine, or come on when
you are driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The oil light could also come on in the
following situations:

The light will come on briefly when you turn on the
ignition to show you that is is working properly. (If it
doesn't come on with the ignition on, you may have
a problem with the fuse or bulb. Have it fixed
right away.)

Sometimes when the engine is idling at a stop, the
light may blink on and off. This is normal.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 you 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.
