6. Install the air duct and resonator assembly (inlet).
Changing Engine OilELS001PL
WARNING:

Be careful not to burn yourself, as the engine and engine oil are 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. Warm up the engine, and check for any oil leaks.
2. Stop the engine and wait for at least 10 minutes.
3. Remove the oil drain plug and oil filler cap to drain the old oil.
4. Install a new washer on the oil drain plug, then install the oil drain plug in the oil pan.
CAUTION:
Clean the drain plug and install with a new washer.
5. Refill the engine with new specified engine oil.
CAUTION:
The refill capacity depends on the oil temperature and drain time. Use the “Refill oil capacity” val-
ues as a reference and check the oil level using the dipstick when filling the engine with oil.
6. Warm up the engine and check the area around the drain plug and oil filter for any oil leaks.
7. Stop the engine and wait for more than 10 minutes.
8. Check the oil level using the dipstick as shown. Add oil as nec- essary and install the oil filler cap.
CAUTION:
Do not overfill the engine with oil.
Changing Oil FilterELS001PM
REMOVAL
1. Remove the engine front undercover using power tool.
2. Remove the oil filter using Tool as shown.
CAUTION:

The oil filter is equipped with a pressure relief valve.

Use Genuine NISSAN oil filter or equivalent.

Be careful not to get burned when the engine and engine
oil are hot.

When removing, prepare a shop cloth to absorb any
engine oil leaks or spills.

Do not allow engine oil to adhere to the drive belts.

Completely wipe off any engine oil that adheres to the engine and the vehicle.
INSTALLATION
1. Remove foreign materials adhering to the oil filter seal mating surface. Oil drain plug : Refer to EM-78, "
CYLINDER BLOCK" .
Oil grade and viscosity : Refer to MA-11, "
Fluids and Lubricants" .
Oil capacity : Refer to MA-11, "
Fluids and Lubricants" .

POWER STEERING FLUID
Revision: November 20092006 QX56
POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelEGS000U9
Check power steering fluid level with engine off, referring to the scale
on reservoir tank.
Use HOT range for fluid temperatures of 50° – 80 °C (122 ° – 176° F).
Use COLD range for fluid temperatures of 0 ° – 30° C (32 ° – 86 °F).
CAUTION:

Do not overfill.

Do not reuse any used power steering fluid.

Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-11, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Checking Fluid LeakageEGS000UA
Check the hydraulic piping lines for improper attachment and for
leaks, cracks, damage, loose connections, chafing or deterioration.
1. Run engine until fluid temperature reaches 50 ° – 80 °C (122 ° –
176° F) in reservoir tank. Keep engine speed idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to
check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over tighten con- nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-21, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid indicating a leak from the steering gear.
Air Bleeding Hydraulic SystemEGS000UB
Incomplete air bleeding causes the following. When this happens, bleed air again.

Air bubbles in reservoir tank.

Clicking noise in oil pump.

Excessive buzzing in oil pump.
NOTE:
When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from
oil pump or gear. This noise is normal and does not affect any system.
1. Stop engine, and then turn steering wheel fully to right and left several times. CAUTION:
Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully right and then fully left, hold for about three seconds. Then check for fluid leakage.
3. Repeat step 2 several times at about three second intervals. CAUTION:
Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that oil pump may be damaged.)
4. Check for air bubbles or cloudy fluid.
5. If air bubbles or cloudiness still exists, stop engine, perform steps 2 and 3 again until air bubbles or cloud- iness does not exist.
6. Stop engine, check fluid level.

FRONT WIPER AND WASHER SYSTEM
Revision: November 20092006 QX56
FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationEKS00BDS
System DescriptionEKS00BDT

Both front wiper relays are located in the IPDM E/R (intelligent power distribution module engine room).

The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input ter-
minals. Terminal combination status is read by the BCM when the wiper switch is turned ON.

BCM controls front wiper LO, HI, and INT (intermittent) operation.

IPDM E/R (intelligent power distribution module engine room) operates the wiper motor according to CAN
communication signals from the BCM.
Power is supplied at all times

through 50A fusible link (letter f , located in the fuse and fusible link box)

to BCM terminal 70, and

through 30A fuse (No. 39, located in the IPDM E/R)

to front wiper relay (located in the IPDM E/R).
With the ignition switch in ON or START position, power is supplied

through 10A fuse (No. 9, located in the fuse block J/B)

to combination switch terminal 14, and

through 10A fuse (No. 59 located in the fuse and relay box)

to BCM terminal 38.
Ground is supplied
