OIL LEVEL
• Before starting the engine make sure the vehicle is parked on a flatand level surface, then check the oil level. If the engine is already
running, turn it off and allow 10 minutes before checking.
• Check that the oil level is within the low (L) to high (H) range as indicated on the dipstick.
• If the engine oil level is out of range, add oil as necessary. Refer to
MA-13, "
Fluids and Lubricants".
OIL APPEARANCE
• Check the engine oil for a white milky appearance or excessive contamination.
• If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
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
• 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 selector lever in the Park “P” position.
1. Check the engine oil level. Refer to LU-8, "
Inspection".
2. Remove engine front undercover using power tool.
3. Disconnect the oil pressure switch harness connector.
4. Remove the oil pressure switch (A).

CAUTION:
• The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
• Always use the oil level gauge to determine when the proper amount of engine oil is in the engine.
8. Warm up engine and check area around drain plug and oil filter for oil leakage.
9. Stop engine and wait for 10 minutes.
10. Check engine oil level. Refer to LU-8, "

Introduction of Periodic MaintenanceINFOID:0000000005145934
Two different maintenance schedules are provi
ded, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage or ti me intervals, whichever comes first.
Maintenance for Off-road Driving (4WD only)INFOID:0000000005145935
Whenever you drive off-road through sand, mud, or wa ter; more frequent maintenance may be required for the
following items:
Brake pads and rotors
Brake lines and hoses
Rear final drive oil, transmission fluid, and transfer fluid
Steering linkage
Drive shafts
Engine air cleaner filter
In-cabin microfilters
Schedule 1INFOID:0000000005145936
EMISSION CONTROL SYSTEM MAINTENANCE
Abbreviations: R = Replace. I = Ins pect. Correct or replace if necessary. [ ]: At the mileage intervals only
Schedule 1Follow Periodic Maintenance Schedule 1 if the driving habits frequently includes
one or more of the following driving conditions:
• Repeated short trips of less than 5 miles (8 km).
• Repeated short trips of less than 10 miles (16 km) with outside temperatures re-
maining below freezing.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi
or door-to-door delivery use.
• Driving in dusty conditions.
• Driving on rough, muddy, or salt spread roads.
• Towing a trailer or using a car-top carrier. Emission Control Sys-
