3.
While running the engine at low idle, remove the cap of oil
filler port (F).
4.
Pull out the dipstick (G) and wipe the oil off with a cloth.
5.
Fully insert the dipstick (G) into the dipstick pipe, then re-
move it.
REMARK
Whenever inserting the dipstick, be sure to insert it into the
dipstick pipe.
The oil level is correct if it is between the marks (A) and (B)
on dipstick (G) marked with "HOT IDLE" side.
6.
If the oil level is below the mark (B), add oil through the oil
filler port (F).
7.
If the oil level is above the mark (A), drain the excessive oil
through drain plug (P), and then check the oil level again.
8.
If the oil is at the correct level, insert the dipstick (G) into
the dipstick pipe and tighten the cap.
NOTICE
• The oil level changes according to the oil temperature. Check the oil level after completing the
warming-up operation of the transfer.
• If the oil temperature of the transfer is low, the oil level at low idling becomes lower than the mark
(B) on "HOT IDLE" side.
(If the oil volume is correct, the oil level is between the marks (A) and (B) on "HOT IDLE" side after
the transfer oil becomes warm.)
Method for checking oil level when the engine is stopped
• As a reference, check the marks (C) and (D) on dipstick
(G) marked with "COLD STOP" side.
• Stop the engine, and wait for 2 hours or longer before
checking.
• For the final oil level check, use "HOT IDLE" side of dip-
stick (G) according to the preceding steps 1 to 8, after
completing the warm-up operation of the transfer.
