WARNING:

Never get under the vehicle while it is supported only by the jack. Always use safety stands to
support the frame when you have to get under the vehicle.

Place wheel chocks at both front and back of the wheels on the ground.
CAUTION:

All applicable State or Provincial (in Canada) laws and local laws regarding the towing operation
must be obeyed.

It is necessary to use proper towing equipment to avoid possible damage during towing opera-
tion. Towing is in accordance with Towing Procedure Manual at dealer.

Always attach safety chains before towing.

When towing, make sure that the transmission, steering system and powertrain are in good order.
If any unit is damaged, dollies must be used.

Never tow an automatic transmission model from the rear
(i.e., backward) with four wheels on the ground as this may
cause serious and expensive damage to the transmission.
2WD MODELS
INFINITI does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:

When towing with the front wheels on the ground: Turn the
ignition key to the OFF position and move the transmission
selector lever to N (neutral) position, turn the ignition key to
OFF position and secure the steering wheel in a straight
ahead position with a rope or similar device. Never place
the ignition key in the LOCK position. This will result in
damage to the steering lock mechanism.

4WD MODELS
INFINITI does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:

Never tow 4WD models with any of the wheels on the
ground as this may cause serious and expensive damage
to the transfer case and transmission.
To w i n g P o i n t
CAUTION:
Never tow the vehicle using only the towing points. To avoid
damaging the vehicle body, use proper towing equipment when
towing.
Vehicle Recovery (Freeing a stuck vehicle)EAS001FZ

Tow chains or cables must be attached only to the main structural members of the vehicle or the
towing hooks (if so equipped). Otherwise, the vehicle body will be damaged.

Use the towing hook (if so equipped) only to free a vehicle stuck in sand, snow, mud, etc. Never
tow the vehicle for a long distance using only the towing hook.

The towing hook is under tremendous force when used to free a stuck vehicle. Never pull the hook
at an angle.

Always pull the cable straight out from the front or rear of the vehicle.

Pulling devices should be routed so they do not touch any part of the suspension, steering, brake,
or cooling systems.

Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
WARNING:

Stand clear of a stuck vehicle.

Do not spin your tires at high speed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.

HEADLAMP (FOR USA)
Revision: November 20092006 QX56

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. 59, located in the fuse and relay box)

to BCM terminal 38.
Ground is supplied

to BCM terminal 67

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.

The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.

Light output is nearly double that of halogen headlamps, affording increased area of illumination.

The light features a high relative spectral distribution at wavelengths to which the human eye is most sen-
sitive. This means that even in the rain, more light is reflected back from the road surface toward the vehi-
cle, for added visibility.
