WARNING:
• Be careful not to burn yourself, as the engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer: try to avoid direct skin
contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as
possible.
1. Position the vehicle so it is level on the hoist.
2. Warm up the engine and check for oil leaks from the engine.
3. Stop engine and wait for 10 minutes.
4. Remove the oil pan drain plug (1) and oil filler cap.
5. Drain the engine oil.
6. Install the oil pan drain plug with a new washer and refill the engine with new engine oil.
CAUTION:
• Be sure to clean the oil pan drain plug and install using a new washer.
• The refill capacity depends on the oil temper ature and drain time. Use these specifications for
reference only. Always use the oil level gauge to determine when the proper amount of oil is in
the engine.
7. Warm up the engine and check around the drain plug and oil filter for oil leaks.
8. Stop the engine and wait for 10 minutes.
9. Check the oil level using the oil level gauge. CAUTION:
Do not overfill the engine with engine oil. Engine oil pressure : Refer to

OIL LEVEL
NOTE:
• Before starting the engine, check the oil level. If the engine is already started, stop it and a llow 10 minutes before checking.
• Check that the oil level is within the range as indicated on the oil level gauge.
• If it is out of range, add oil as necessary.
ENGINE OIL APPEARANCE
• Check engine oil for white milky appearance or excessive contamination.
• If engine oil becomes milky, it is highly probable t hat it is contaminated with engine coolant. Repair or
replace damaged parts.
OIL LEAKAGE
Check for oil leakage around the following areas:
•Oil pan
• Oil pan drain plug
• Oil pressure switch
• Oil filter
• Oil cooler
• Intake valve timing control cover and intake valve timing control solenoid valve
• Front cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seal (front and rear)
OIL PRESSURE CHECK
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Put the CVT shift selector in the Park “P” position.
1. Check the oil level.
2. Remove fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded View"
.
3. Disconnect oil pressure switch harness connector at the oil pressure switch. Remove oil pressure switch and install Tools.
CAUTION:
Do not drop or shock oil pressure switch.
4. Start the engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load, using Tool. NOTE:
• When engine oil temperature is low, engine oil pressure becomes high.
