Checking Oil Level — 3.0 Diesel Engine
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals. The best time to check the
oil level is before starting the engine after it has been
parked overnight. When checking oil after operating the
engine, first ensure the engine is at full operating tempera-
ture, then wait for five minutes after engine shutdown to
check the oil.
1 — MAX Mark
2 — MIN Mark
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil only
when the level on the dipstick is below the “MIN” mark.
The total capacity from the MIN mark to the MAX mark is
1 qt (1 L).
CAUTION!
Overfilling or underfilling the crankcase will cause oil
aeration or loss of oil pressure. This could damage your
engine.
NOTE: It is possible for your oil level to be slightly higher
than a previous check. This would be due to diesel fuel that
may temporarily be in the crankcase due to operation of
the diesel particulate filter regeneration strategy. This fuel
will evaporate out under normal operation.
Never operate the engine with oil level below the “MIN”
mark or above the upper “MAX” mark.
Maintenance-Free Batteries
Your vehicle is equipped with a maintenance-free battery.
The top of the maintenance-free battery is permanently
sealed. You will never have to add water, nor is periodic
maintenance required.
