A: INSPECTION
CAUTION:
The level of ATF varies with fluid temperature.
Pay attention to the fluid temperature when
checking ATF level.
1) Raise the ATF temperature by driving a distance
of 5 to 10 km (3 to 6 miles). Otherwise, idle the en-
gine to raise ATF temperature to 60 — 80 °C (140
— 176 °F) on Subaru Select Monitor. <Ref. to AT-
18, READ CURRENT DATA, OPERATION, Suba-
ru Select Monitor.>
2) Make sure the vehicle is level.
3) After selecting all positions (P, R, N, D, 3, 2, 1),
set the select lever in "P" range. Measure the ATF
level with the engine idling for one or two minutes.

(B) Upper level
(C) Lower level
4) Make sure that ATF level is above the center of
upper and lower marks.
NOTE:
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.
5) If the ATF level is below the center between up-
per and lower marks, add the recommended ATF
until the ATF level is found above the center be-
tween upper and lower marks.
CAUTION:
• Use care not to exceed the upper limit level.
• Remember that the addition of ATF to the up-
per limit mark when the transmission is cold
will result in overfilling of ATF, causing a trans-
mission failure.
6) Check ATF level after raising ATF temperature
to 60 — 80 °C (140 —176 °F) by running the vehi-
cle or by idling the engine again.
7) Check the ATF for leaks.
