SERVICE AND MAINTENANCE
Engine oil is an important factor determining engine performance and longevity. Be
sure to use only the specified oil and oil filters. The engine oil level must be checked
and the oil should be changed regularly according to the Maintenance Schedule.
NOTE
•
When particulate matter (PM) has accumulated to a preset level in the diesel
particulate defuser (DPD) filter, the filter is automatically regenerated through
combustion. To make this regeneration (combustion) possible, a small amount
of fuel is injected into the engine combustion chamber after firing. This causes
fuel to gradually become mixed with the engine oil, and the engine oil level
will rise beyond the original level. This does not indicate a malfunction of the
engine.
Park the vehicle on a level surface and check the engine oil level before starting 30
minutes after turning off the engine. To check the oil level, remove the oil dipstick, wipe
off the end with a clean cloth, reinsert it and then gently remove it.
If the oil level is between the "Inspection MAX" and "MIN" marks, the oil is at the
correct level. Also check to see if there are any oil leaks.
