Function inspection
1. Engine oil level check
(1) Park the vehicle on a level surface.
(2) Remove the oil level gauge and wipe away the oil.
(3) Reinsert the oil level gauge all the way. Be sure that the oil level gauge is correctly inserted and properly orientated.
(4) Pull out the oil level gauge again, and check both sides of the oil level gauge. Use a lower side to determine the engine
oil level. If the engine oil level is below the L mark, check the engine for oil leakage and refill the oil to bring the level up
to the F mark.
(5) Start the engine to circulate the oil in the engine.
(6) Five minutes after stopping the engine, check that the engine oil
& ' level is between the L and F marks of oil level gauge. If the oil level
is low, check for oil leakage and refill the oil up to the F mark.
( NOTE:
• To prevent overfilling of the engine oil, do not refill the oil above
the F mark when the engine is cold.
• As the oil level gauge is used for daily maintenance, the F and
L marks are set assuming that the engine is cold.

3. Oil filter union installation
(1) Install the oil filter union.
Standard value:T=45N·m {459kgf·cm} {33.2ft·lbf}
NOTE:
Perform this operation as necessary.
4. Oil filter installation
(1) Remove the dirt and foreign matters on the engine side installing surface and inner side.
(2) Apply a thin coat of engine oil to the seal rubber of a new oil filter.
(3) Tighten the oil filter by hand.
CAUTION:
Be careful not to damage the seal rubber of oil filter.
(4) Tighten the oil filter using the SST.
SST 18332AA020
Standard value:T=14N·m {143kgf·cm} {10.3ft·lbf}
CAUTION:
• When extending the overall tool length by combining a torque wrench with the SST during tightening, tightening to the point
where the value on the torque wrench reaches the specified tightening torque will cause the actual tightening torque to be
excessive.
• This manual only indicates the specified tightening torque. If using an SST, it is necessary to use the following formula to
calculate the proper torque wrench reading.
• Formula T'=T×L2/(L1+L2)
T' Torque wrench reading [N·m {kgf·cm}]
T 14N·m {143kgf·cm}{10.3ft·lbf}
/ / L1 0.080m {3.150 in}
L2 Torque wrench effective length (m {in})
NOTE:
• This torque value is valid when the SST and torque wrench are
aligned on a line.
• Attach the SST and torque wrench so that they are aligned on
a line.
