A: INSPECTION
1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe it clean.
3) Reinsert the level gauge all the way. Be sure that
the level gauge is correctly inserted and in the
proper orientation.
4) Remove it again and note the reading. If the en-
gine oil level is below the “L” line, add oil to bring
the level up to “F” line.
5) After turning off the engine, wait a few minutes
for the oil to drain back into the oil pan before
checking the level.
6) Just after driving or while the engine is warm, en-
gine oil level may show in the range between the
“F” line and notch mark. This is caused by thermal
expansion of the engine oil.
NOTE:
To prevent overfilling the engine oil, do not add oil
above the “F” line when the engine is cold.
B: REPLACEMENT
1) Open the engine oil filler cap for quick draining of
the engine oil.
2) Lift up the vehicle.
3) Drain the engine oil by loosening the engine oil
drain plug.
NOTE:
Prepare the container for draining of engine oil.
4) Tighten the engine oil drain plug after draining
engine oil.
NOTE:
• Replace the drain plug gasket.
• Refer to COMPONENT of General Description
for tightening torque. <Ref. to LU(H4SO)-3, COM-
PONENT, General Description.>
5) Fill engine oil through the filler duct up to upper
level on level gauge. Make sure that the vehicle is
placed level when checking oil level. Use the en-
gine oil of proper quality and viscosity, selected in
accordance with the table in figure.
