Engine Oil
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 get back down 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
lower.
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 exp\
lains what
kind
of oil to use. For crankcase capacity, see “Capacities and Specification\
s”

I Don’t add too much oil. If your engine has so much oil that the oil level
gets above the upper mark that
shows the proper operating range, your
engine could be damaged.

Automatic Transmission Fluid
When to Check and Change:
A good time to check your automatic transmission 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 a General Motors dealership Sewice 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 I
I
Too much or too little fluid can damage your transmission. Too much can
mean that some of the fluid could come out and fail
on hot engine parts,
I
starting a fire. Be sure to get an accurate reading if you check-your
transmission fluid.
Wait at least
30 minutes before checking the transmission fluid level if you
have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic-especially in hot weather.
