oil of the correct grade and quality
whenever its level exceeds the
"Position A" mark.
Fuel will gradually become mixed
with the engine oil, thinning it out.
Be sure to change the oil at the
specified intervals.
The oil level cannot be checked
correctly when the engine is
running.
If the engine has been running, wait
at least 30 minutes before checking.
Adding the Engine Oil
When the engine oil level is near or
below the "MIN" mark on the oil
dipstick, remove the oil filler cap (1)
and add the oil. Remove the oil
dipstick (2) at this time. Use only the
specified engine oil.
Caution
When adding oil, be careful not to
spill any, but keep a workshop rag
handy just in case there are any
spills. If any oil should spill onto
the engine, carefully wipe it away.
If this precaution is not taken, the
spilled oil could ignite and a fire
could spread.
Do not leave flammable items,
such as rags or gloves, in the
engine compartment. They could
cause a fire. You and others could
be seriously injured.
Engine oil lubricates and cools the
engine's internal components. The
quality of the oil is degraded and the
quantity of oil is reduced by
evaporation, discharge and
combustion during the operation of
the engine. Continually using the
same oil without checking the level,
or without replenishing and
changing it could cause seizure or
damage to the engine.
Prevent dirt from entering the filler
port when adding the oil. If foreign
matter mixes with the oil, it could
damage the engine.
Adding oil above the "Position A"
mark on the oil dipstick could result
in faulty engine operation. Be sure
to check the oil level by using the oil
dipstick.
Failure to use the recommended
engine oil could result in engine or
DPF breakdown, or in poor fuel
efficiency. Be sure to use the
recommended engine oil.
Choosing the Right Quality Oil
If you do not use the oil intended for
a vehicle equipped with a Diesel
Particulate Filter (DPF), both the
engine and the DPF may break
down and fuel economy may
decrease. Be sure, therefore, to use
the oil intended for vehicles
equipped with DPF.
