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.

The engine oil dipstick handle
is the yellow loop near
the front of the engine.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don't, the oil dipstick
might not show the actual
level.

To Check Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back
in all the way. Remove it again,
keeping the tip down, and check the level.

When to Add Oil
If the oil is at or below the ADD mark, then you’ll need
to add some oil. But you must use the right kind. This
part explains what kind
of oil to use. For crankcase
capacity, see “Capacities and Specifications” in the
Index.
NOTICE:
Don’t add too much oil. If your engine has
so much oil that the oil level gets above the
cross-hatched area that shows the proper
operating range, your engine could be damaged. 3.1L L82 (Code M) Engine 3.8L L27 (Code L) Engine

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed. Refer to the
Maintenance Schedule
to determine when to change
your fluid. See “Scheduled Maintenance Services” in
the
Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Buick dealership
Service Department.
If you do it yourself, be sure
to follow all the instructions
here, or you could get
a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F (82°C
to
93 ” C).
Get the vehicle warmed up by driving about 15 miles
(24
km) when outside temperatures are above 50°F
(10°C). If it’s colder than 50°F (IOOC), you may have
to drive longer.
To check the fluid level
0 Park your vehicle on a level place. Keep the engine
running.
With the parking brake applied, place the shift lever
in PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds
in each range. Then, position the shift
lever
in PARK (P).

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See “Recommended
Fluids and Lubricants”
in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on the
dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole
to bring it to the proper level.
It doesn’t take much fluid, generally less than a pint
(OSL). Don ’t ouefill. We recommend you use only fluid
labeled DEXRON@-111, because fluid with that label is
made especially for your automatic transaxle. Damage
caused by fluid other than DEXRON@-I11 is not covered
by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How
to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating or if
you need to add coolant to your
radiator, see “Engine Overheating” in the Index.
The proper coolant for your Buick will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262 OF (1 28 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets “GM
Specification
1825-M,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825-M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant flush and refill.
If you use
this mixture, you don’t need to add anything else.
