The engine oil level indicator is located on the right side of the 4.7L engine (Fig. 92).
CRANKCASE OIL LEVEL INSPECTION
CAUTION: Do not overfill crankcase with engine oil, pressure loss or oil foaming can result.
Inspect engine oil level approximately every 800 kilometers (500 miles). Unless the engine has exhibited loss of oil pressure, run the engine for about
five minutes before checking oil level. Checking engine oil level on a cold engine is not accurate.
To ensure proper lubrication of an engine, the engine oil must be maintained at an acceptable level. The acceptable levels are indicated between the
ADD and SAFE marks on the engine oil dipstick.

3. Wipe dipstick clean.
4. Install dipstick and verify it is seated in the tube.
5. Remove dipstick, with handle held above the tip, take oil level reading.
6. Add oil if level is below the SAFE ZONE on dipstick.
