to combination meter terminal 8, and

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

to BCM terminal 70.
With the ignition switch in the ON or START position, power is supplied

to ignition relay, located in the IPDM E/R, and

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 24, and

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

to BCM terminal 38.
Ground is supplied

to BCM terminal 67 and

to combination meter terminal 17

through grounds M57, M61 and M79, and

to IPDM E/R terminals 38 and 59

through grounds E9, E15 and E24.
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This
input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R con-
trols the headlamp low relay coil. When energized, this relay directs power

through 15A fuse (No. 41, located in the IPDM E/R)

through IPDM E/R terminal 54

to front combination lamp RH terminal 5, and

through 15A fuse (No. 40, located in the IPDM E/R)

through IPDM E/R terminal 52

to front combination lamp LH terminal 5.
Ground is supplied

to front combination lamp LH and RH terminal 1

through grounds E9, E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input request-
ing the headlamp high beams to illuminate. This input is communicated to the IPDM E/R across the CAN com-
munication lines. The CPU of the combination meter controls the ON/OFF status of the HIGH BEAM indicator.
The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power

through 10A fuse (No. 34, located in the IPDM E/R)

through IPDM E/R terminal 56

to front combination lamp RH terminal 6, and

through 10A fuse (No. 35, located in the IPDM E/R)

through IPDM E/R terminal 55

to front combination lamp LH terminal 6.
Ground is supplied

to front combination lamp LH and RH terminal 2

through grounds E9, E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
XENON HEADLAMP
Xenon type headlamp is adopted to the low beam headlamps. Xenon bulbs do not use a filament. Instead,
they produce light when a high voltage current is passed between two tungsten electrodes through a mixture
of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic control
of the power supply gives the headlamps stable quality and tone color.
Following are some of the many advantages of the xenon type headlamp.

FRONT FOG LAMP
Revision: August 20072004 QX56
Aiming AdjustmentEKS007BF
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

Keep all tires inflated to correct pressure.

Place vehicle on level ground.

See that vehicle is unloaded (except for full levels of coolant,
engine oil and fuel, and spare tire, jack, and tools). Have the
driver or equivalent weight placed in driver seat.
Adjust aiming in the vertical direction by turning the adjustment
screw.
NOTE:
Access adjustment screw from underneath front bumper. Turn screw
clockwise to raise pattern and counterclockwise to lower pattern.
1. Set the distance between the screen and the center of the fog
lamp lens as shown.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 200 mm (7.9 in) below the height of
the fog lamp centers as shown.

When performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.

Bulb Replacement EKS007BG
1. Remove the front turn/fog lamp assembly. Refer to LT-79, "Removal and Installation" .
2. Turn the bulb cover counterclockwise to remove it.
3. Unlatch retaining spring.
4. Remove bulb and disconnect the connector.
CAUTION:

Do not touch the glass of bulb directly by hand. Keep
grease and other oily substances away from it. Do not
touch bulb by hand while it is lit or right after being
turned off. Burning may result.

Do not leave bulb out of fog lamp reflector for a long time
because dust, moisture smoke, etc. may affect the perfor-
mance of fog lamp. When replacing bulb, be sure to
replace it with new one.
Installation is in the reverse order of removal.
Removal and InstallationEKS007BH
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb.
CAUTION:

Do not leave fog lamp assembly without bulb for a long period of time. Dust, moisture, smoke, etc.
entering the fog lamp body may affect the performance. Remove the bulb from the headlamp
assembly just before replacement bulb is installed.

Grasp only the plastic base when handling the bulb. Never touch the glass envelope. Touching the
glass could significantly affect the bulb life and/or fog lamp performance.
1. Remove the front turn/fog lamp finisher.
2. Remove bolt and pull fog lamp out of front fascia.
3. Disconnect electrical connector.
Installation is in the reverse order of removal.

GASOLINE ENGINE OIL

SAE 5W-30 viscosity oil is preferred for all temperatures. SAE
10W-30 and 10W-40 viscosity oil may be used if the ambient
temperature is above -18°C (0°F).

Use of 5W-30 viscosity oil will increase fuel economy.
ANTI-FREEZE COOLANT MIXTURE RATIO
The engine cooling system is filled at the factory with a high-quality, long life, year-round, anti-freeze coolant
solution. The anti-freeze solution contains rust and corrosion inhibitors. Therefore, additional cooling system
additives are not necessary.
CAUTION:

When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Anti-freeze
coolant or equivalent with the proper mixture ratio of 50% anti-freeze and 50% demineralized water
or distilled water.

Other types of coolant solutions may damage your cooling system.

6. Install the air duct and resonator assembly (inlet).
Changing Engine OilELS0010A
WAR NIN G:

Be careful not to burn yourself, as the engine oil is 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 the specified oil.
CAUTION:

Clean the drain plug and install with a new washer.

The refill capacity depends on the oil temperature and drain time. Use the oil capacity value as a
reference and check the oil level using the dipstick when filling the 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.
