Engine Exhaust Running Your Engine While
You’re Parked
It’s better not to park with the engine running. But if you
ever have to, here are some things to know.

Speedometer/Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour
(kmh). 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 Buick has
a tamper-resistant odometer. If you see
silver lines between the numbers, you’ll know someone
has probably tampered with it and the numbers may not
be true.
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 it must be. But if
it can’t, then it’s 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.
Tachometer
x
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the red area, or engine damage may occur.

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. 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.
Fuel Gage
I UNLEADED FUEL ONLY
I
Your fuel gage tells you
about how much fuel you
have left when the ignition
is on. When the indicator
nears
EMPTY (E), you still
have a little fuel left, but
you should get more soon.
Here are some things owners ask about. All these
situations are normal and do not show
a problem with
your fuel gage:
0 At the service station, the pump shuts off before the
gage reads
FULL (F).

Anti-Lock Brake System Warning Light
-
lo- 0 system, this light will come
With
the anti-lock brake
RPM x1000 on when you start your
engine and it will stay on
for three seconds. That’s
normal. If the light doesn’t
come on, have it fixed
so it
will be ready to warn you
if
there is a problem.
If the light flashes when you’re driving, you don’t have
anti-lock brakes and there could be a problem with your
regular brakes.
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.
Have the vehicle towed for service. (See “Towing Your
Vehicle’’ in the Index.)
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, your Buick needs service. If the
light
is on but not flashing and the regular brake system
warning light isn’t
on, you still have brakes, but you
don’t have anti-lock brakes.

Malfunction Indicator Lamp (Check Engine Light)
111 A computer monitors
operation of your fuel,
ignition and
emission
control systems. This light
should come on when the
SOON ignition is on, but the
engine is not running, as a
check to show you it is
working.
If it does not come on at all, have it fixed right away. If
it stays on, or it comes on while you are driving, the
computer is indicating that you have a problem. You
should take your vehicle in for service soon.
NOTICE:
If you keep driving your vehicle with this light on,
after a while the emission controls won’t work as
well, your fuel economy won’t be as good and your
engine may
not run as smoothly. This could lead to
costly repairs not covered by your warranty.
Oil 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 three other
situations:
0 When the ignition is on but the engine is not running,
the light will come on as a test to show you
it is
working, but the light will go out when you turn the
ignition to START. 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.

problems can be costly and

warranty.
Low Oil Level Light
Your engine is equipped
with an oil level monitoring
system. When the ignition
key
is turned on, the LOW
OIL LEVEL light will
briefly flash. If the light
does not flash, have it fixed
so it will be ready to warn
you
if there’s a problem.
If the light stays on, stop the vehicle on a level surface
and turn
the engine off. Check the oil level using the
engine oil dipstick. (See “Engine Oil” in the Index.) If
the light does not flash, have the low oil level sensor
system repaired
so it will be ready to warn you if there’s
a problem.
The oil level monitoring system only checks oil level
during
the brief period between key on and engine
crank. It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned off for a
considerable period of time, allowing the oil normally in
circulation
to drain back into the oil pan.
