level檢測步驟（你的車也許會不同，也許一樣）：

10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all positions from ”P” to ”L”,
and then shift into ”P” position.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re-insert the dipstick and check that the
fluid level is in the ”HOT” range.
(d) Do this check with the fluid at normal driving temperature (70 - 80°C, 158 - 176°F).
HINT:
Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speeds, in hot weather, in heavy traffic or pulling a trailer.
