When diagnosing low oil pressure concerns, verify the oil pressure reading. A reading may indicate low although the oil level is full. If the crankcase is
overfilled with as little as 0.95L (1 qt) of oil, aeration may occur. Driving the vehicle for an extended period of time with aerated oil could cause internal
engine damage.
Verify that the vehicle crankcase is not overfilled before attempting other repairs. Wait at least 15 minutes after turning the engine off before verifying
the oil level. Be sure that the oil level indicator is fully seated in the tube when verifying the oil level. The Owner's Manual shows the correct crankcase
capacity of 6.1 L (6.5 qts) with the oil filter.
Also, the engine oil level indicator was changed in production. The change is to meet international language requirements. All writing and two of the
holes in the operating range have been removed from the indicator. The illustrations show the first and second design indicators and the proper operating
range.
