NOTE:
The level of ATF varies with fluid
temperature. Pay attention to the
fluid temperature when checking oil
level. A change in the ATF level by
oil temperature is shown in the follow-
ing figure.
b. Ensure the vehicle is level and set
the selector lever in "P" range.
Measure fluid level with the engine
idling.
NOTE:
After running, idle the engine for one
or two minutes before measurement
c. If the fluid level is below the lower
limit mark, add the recommended
A TF until the fluid level is found
within the specified range (within
upper and lower limit marks). When
the transmission is hot, the level
should be above the center of upper
and lower marks, and when it is
