Engine Oil and Filter

Checking

Check the engine oil a couple of minutes after shutting the engine
off, with the car parked on level ground. Remove the dipstick and wipe it clean. Reinsert it all the way down, then pull it out and read
the level. The level should be between the upper and lower marks.

FILLER CAP

Adding
If the level has dropped close to the lower mark, add oil until it is
even with the upper mark. 1 .Turn the oil filler cap counterclockwise to remove. Add oil, then check the level again. Do not overfill.
2. Reinstall the cap and twist clockwise until it stops.

CAUTION:
Be sure the oil filler cap is correctly replaced before starting the

engine.
Engine oil is a major factor affecting the performance and

service life of the engine; you should use only a premium quality

detergent oil labeled SG grade.
LOOK FOR THIS LABEL
ON THE OIL CONTAINER

Use the proper viscosity oil for the
climate in which you drive:
Some oil labels may also include additional designations of quality
such as CC or CD. However, these are acceptable only when
used together with SG.
NOTE:

5W-30 viscosity
oil is recommended for improved fuel economy.

Transmission Oil/Fluid Check
Transmission oil/fluid must be checked with the engine off and the
car on level ground.
If the engine has been running, some engine components may
be hot enough to burn you. Keep hands away from the radiator fan. The fan may start
automatically without warning and run for up to 15 minutes,
even after the engine is turned off.

CAUTION:

If the oil/fluid level is low, check for possible leaks before adding
oil. Do not overfill.
Since the transmission and differential are in the same housing, you
are actually checking both oil/fluid levels in one procedure. Change
transmission oil/fluid according to the Maintenance Schedule on
page 78 .

5-Speed

Remove the oil filler bolt (beside the right axle). Feel inside the boh
hole with your finger. If the oil is up to the bottom edge of the hole,
the oil level is correct. If it is not, slowly add oil until it runs out of
the hole, then reinstall the bolt and tighten it securely with a wrench.
