(2) Move the shift lever back and forth between N and D at 1.5 seconds interval for six seconds.

(3) The D shift indicator on the combination meter comes on for two seconds. This indicates that the fluid temperature check mode has been started.

(4) The D shift indicator comes on again when the fluid temperature reaches 46 C (115 F) and blinks when it exceeds 56 C (130 F).

(5) Allow the engine to idle until the fluid temperature reaches 46 C (115 F).

6.

FLUID LEVEL CHECK NOTICE: The fluid temperature must be between 46 C (115 F) and 56 C (130 F) to check the fluid level. (a) Remove the overflow plug with the engine idling. (b) Check that the fluid comes out of the overflow tube.

If fluid does not come out, proceed to step 7.
