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.
Check Oil Level Light (Option)
CHECK
OIL LEVEL
The CHECK OIL LEVEL
light comes on for three
seconds as a bulb check
each time the ignition key is
turned to the
RUN position.
If the light doesn’t come on,
have your vehicle serviced.
If the engine oil is more than one quart low, the light
will come on briefly, then go off for
15-25 seconds, and
then come back on for
20-40 seconds.
However, the system will not register low engine oil if it
has not been more than eight minutes since the engine
was last shut off.
If the CHECK OIL LEVEL light comes back on, the
engine oil should be checked at the dipstick then
brought up to the proper level if necessary. See “Engine
Oil” in the Index.

It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
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.
Checking 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:
I
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.
Add engine oil at the engine oil fill cap next to the
oil dipstick.
Just fill it enough to put the level somewhere in the
proper operating range. Push the dipstick all the way
back in when you’re through.
What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
If you change your
own oil, be sure you
use oil that has the
Starburst symbol on
the front of the oil
container.
If you have
your oil changed
for
you, be sure the oil put
into your engine is
American Petroleum
Institute certified for
gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

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
It doesn’t take much fluid, generally less than a pint
(0.5 L). Don’t ovel-fill. 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.
dipstick hole to
bring it to the proper level.
After adding fluid, recheck the fluid level as
described under “How to Check.”
0 When the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL
TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
The following explains your cooling system and how
to add coolant when
it is low. If you have a problem
with engine overheating, see “Engine Overheating” in
the Index.
A 50/50 mixture of water and the proper coolant for
your Buick will:
Give freezing protection down to -34°F (-37°C).
9 Give boiling protection up to 265 OF ( 129 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
