A: INSPECTION
1) Raise the ATF temperature to 70 to 80°C (158 to
176°F) from 20 to 30°C (68 to 86°F) (when cold) by
driving a distance of 5 to 10 km (3 to 6 miles).
NOTE:
The level of ATF varies with fluid temperature. Pay
attention to the fluid temperature when checking oil
level.
(A) ATF level gauge
(B) Upper level
(C) Lower level
2) Make sure the vehicle is level. After selecting all
positions (P, R, N, D, 3, 2, 1), set the select lever in
"P" range. Measure the fluid level with engine
idling.
NOTE:
After running, idle the engine for 1 or 2 minutes be-
fore measurement.
3) If the fluid level is below the center between up-
per and lower marks, add the recommended ATF
until the fluid level is found within the specified
range (above the center between upper and lower
marks). When the transmission is hot, the level
should be above the center of upper and lower
marks, and when it is cold, the level should be
found below the center of these two marks.
CAUTION:
• Use care not to exceed the upper limit level.
• ATF level varies with temperature. Remem-
ber that the addition of fluid to the upper limit
mark when the transmission is cold will result
in the overfilling of fluid.

4) Fluid temperature rising speed
• By idling the engine
Time for temperature rise to 70°C (158°F) with at-
mospheric temperature of 0°C (32°F): More than
25 minutes
<Reference>
Time for temperature rise to 30°C (86°F) with atmo-
spheric temperature of 0°C (32°F): Approx. 8 min-
utes
• By running the vehicle
Time for temperature rise to 60°C (140°F) with at-
mospheric temperature of 0°C (32°F): More than
10 minutes
5) Method for checking fluid level upon delivery or
at periodic inspection
Check the fluid level after a warm-up run of approx.
10 minutes. During the warm-up period, the auto-
matic transmission functions can also be checked.
