ON-VEHICLE INSPECTION
1. CHECK ENGINE OIL LEVEL
a. Warm up the engine, stop the engine and wait for 5 minutes.
b. Check that the engine oil level is between the L and F marks of the oil dipstick. If low, check for leakage and add oil up to the F mark.

NOTICE: Do not add engine oil above the F mark.





2. CHECK ENGINE OIL QUALITY
a. Check the oil for deterioration, water intrusion, discoloration or thinning. If the quality is visibly poor, replace the oil. Oil grade: Use API grade SL "Energy-Conserving" or ILSAC multigrade engine oil. SAE 5W-20 and SAE 0W-20 engine oil may be used. However, SAE 0W-20 is the best choice for good fuel economy and good starting in cold weather.

3. CHECK OIL PRESSURE
a. Disconnect the oil pressure switch connector.





b. Using a 24 mm deep socket wrench, remove the oil pressure switch.





c. Install the oil pressure gauge.
d. Warm up the engine.
