aiming.
HEADLAMP AIMING
NOTE:

Before performing aiming adjustment, check the following:
–Confirm headlamp aiming switch is set to "0" (zero) position.
–Ensure all tires are inflated to correct pressure.
–Place vehicle and screen on level surface.
–Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant and engine oil filled to correct level, and fuel tank full.
–Confirm spare tire, jack and tools are properly stowed.
–Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
–Use adjusting screw to perform aiming adjustment

FRONT COMBINATION LAMP ASSEMBLY
CAUTION:

Disconnect battery negative terminal before touching xenon bulb or headlamp wiring harness
assembly.

Turn headlamp switch OFF before disconnecting headlamp harness connector.

Do not touch bulb by hand right after being turned off. Burning may result.

Do not touch the glass of bulb directly by hand. Keep grease and other oily substances away from
it.

Do not turn xenon bulb ON when xenon bulb is removed from front combination lamp assembly.

After installing the bulb, be sure to install the bulb socket securely to ensure watertightness.

Do not leave bulb out of front combination lamp assembly for a long time because dust, moisture,
smoke, etc. may affect the performance of the lamp. When replacing bulb, be sure to replace it
with a new one.

HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -
Revision: November 20092006 QX56
System DescriptionEKS00B8E
Daytime light system turns on daytime light lamps while driving. Daytime light lamps are not turned on if
engine is activated with parking brake applied. Release parking brake to turn on daytime light lamps. The
lamps turn off when lighting switch is in the 2ND position or AUTO position (Headlamp is "ON") and when light-
ing switch is in the PASSING position. (Daytime light lamps are not turned off only by parking brake itself.)
A parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line.
OUTLINE
Power is supplied at all times

to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room), and

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

to BCM terminal 70, and

through 20A fuse (No. 53, located in the IPDM E/R)

to CPU (central processing unit) of the IPDM E/R, and

through 10A fuse [No. 19, located in the fuse block (J/B)]

to combination meter terminal 8, and

through 10A fuse (No. 45, located in the IPDM E/R)

to daytime light relay terminals 2 and 5.
When the ignition switch is in ON or START position, power is supplied

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

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

to BCM terminal 38, and

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

to combination meter terminal 24.
Ground is supplied

to BCM terminal 67 and

to combination meter terminal 17

through grounds M57, M61 and M79.
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, the IPDM
E/R receives input requesting the daytime lights illuminate. This input is communicated across the CAN com-
munication lines. The CPU of the IPDM E/R controls the daytime light relay coil. When energized, this relay
directs power

through daytime light relay terminal 3

to front combination lamp LH terminal 2

through front combination lamp LH terminal 6

to IPDM E/R terminal 55

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

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

through IPDM E/R terminal 56

to front combination lamp RH terminal 6.
Ground is supplied

to front combination lamp RH terminal 2

through grounds E9, E15 and E24.
With power and ground supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.
