OIL LEVEL

Before starting the engine make sure the vehicle is parked on a
flat and level surface, then check the oil level. If the engine is
already running, turn it off and allow 10 minutes before check-
ing.

Check that the oil level is within the low (L) and high (H) range
as indicated on the dipstick.

If the engine oil level is out of range, add oil as necessary. Refer
to GI-46, "
Recommended Chemical Products and Sealants" .
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 sensor

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
CAUTION:

Be careful not to burn yourself, as engine oil may be hot.

Put the selector lever in the Park “P” position.
1. Check the engine oil level. Refer to LU-7, "
OIL LEVEL" .
2. Remove engine front undercover using power tool.
3. Disconnect the oil pressure sensor harness connector.
4. Remove the oil pressure sensor.

GENERAL MAINTENANCE
Revision: November 20092006 QX56
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).Brakes
Check that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
booster Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Keep the floor
mats away from the pedal. ACC-5, "
ADJUSTABLE
ACCELERATOR
PEDAL",
BR-17, "On-
Vehicle Service"
Parking brake Check that the parking brake control has the proper travel and make sure that
the vehicle is held securely on a fairly steep hill when only the parking brake is
applied. PB-9, "Parking Brake
Control"
Automatic transmis-
sion “Park” mecha-
nismOn a fairly steep hill check that the vehicle is held securely with the selector

Windshield washer
fluid Check that there is adequate fluid in the tank.
—
Engine coolant level Check the coolant level when the engine is cold. —
Radiator and hoses Check the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation,
deterioration or loose connections. —
Brake fluid level Make sure that the brake fluid level is between the “MAX ” and “ MIN” lines on the
reservoirs MA-28
Battery
Check the fluid level in each cell. It should be between the “MAX ” and “MIN ”
lines. Vehicles operated in high temperatures or under severe conditions require
frequent checks of the battery fluid level. —
Engine drive belt Make sure that no belt is frayed, worn, cracked or oily. MA-13
Engine oil levelCheck the level on the dipstick after parking the vehicle on a level spot and turn-
ing off the engine. —
Power steering fluid
level and lines Check the level on the reservoir with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.
MA-29
Automatic transmis-
sion fluid levelCheck the level on the dipstick after putting the selector lever in
“P ” with the
engine idling. MA-22
Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it. MA-22
Underbody
The underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate. —
Fluid leaks Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping from the air conditioner after use is
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately. —
