FRONT FOG LAMP
Revision: October 20052005 QX56
Aiming AdjustmentEKS00B9M
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.

Removal and InstallationEKS00B9O
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.

With the ignition switch in the ON or START position, power is supplied

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

to BCM terminal 38, and

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

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

ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU of the IPDM E/R controls the tail lamp relay coil, which, when
energized, directs power

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST or 2ND position (or if auto light system is acti-
vated), and the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the illumination lamps remain illuminated for 5 minutes, then the illumination lamps are
turned off.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps are turned off by the battery saver control, the illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

POWER STEERING GEAR AND LINKAGE
Revision: October 20052005 QX56
15. Measure pinion rotating torque using Tool, then confirm whether
the reading is within the specified value. If the reading is not
within the specified value, readjust screw angle with adjusting
screw. If the reading is still not within the specified value or the
rotating torque of adjusting screw is less than 5 N·m (0.51 kg-m,
44 in-lb), replace the steering gear assembly.
16. Turn pinion to the full left lock position with inner socket to gear housing assembly.
17. Mount dial gauge to rack as shown. Measure vertical movement
of rack when pinion is turned counterclockwise with torque of
19.6 N·m (2.0 kg-m, 14 ft-lb). Check if reading is within the spec-
ified value. If reading is outside of the specification, readjust
screw angle with adjusting screw. If reading is still outside of
specification, or if the rotating torque of adjusting screw is less
than 5 N·m (0.51 kg-m, 44 in-lb), replace the steering gear
assembly.
18. Install large-diameter side of boot to gear housing assembly.
19. Install small-diameter side of boot to the mounting groove of
inner socket boot.
20. Install boot clamp to the small-diameter side of boot.Pinion rotating torque:
Around neutral position (within ±100°)
Average “A”:
0.8 − 2.0 N·m (0.09 − 0.20 kg-m, 7 − 17 in-lb)
