NISSAN 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 or rear
wheels on the ground (If you do not use towing dollies): Set
the free-running hubs to the free position and move the
transfer case shift lever into the “2H” position.

When towing with the front on the ground: Turn the ignition
key to the 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.
Towing Point
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.
WA RN ING:

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.

to rear power vent window motors terminal 1.
Ground is supplied

to rear power vent window relay (CLOSE) terminal 4

through rear power vent window relay (CLOSE) terminal 3

to rear power vent window motors terminal 2.
Then, the motors open the windows until the switch is released.
AUTO OPERATION
The power window AUTO feature enables the driver to open or close the window without holding the window
switch in the down or up position.
POWER WINDOW SERIAL LINK
Main power window and door lock/unlock switch, power window and door lock/unlock switch RH, rear power
window control units and BCM transmit and receive the signal by power window serial link.
The signal is transmitted from BCM to main power window and door lock/unlock switch and power window and
door lock/unlock switch RH

Keyless power window down signal.

Rear power window switch illumination.
The signal is transmitted from main power window and door lock/unlock switch to power window and door
lock/unlock switch RH

Front door window RH operation signal.

Power window control by front door lock assembly LH (key cylinder switch) signal.

Power window lock signal.

Retained power operation signal.

Rear power window operation.
POWER WINDOW LOCK
The power window lock is designed to lock operation of all windows except for front door window LH.
When in the lock position, the power window lock signal is transmitted to power window and door lock/unlock
switch RH by power window serial link. This prevents the power window motor from operating.
RETAINED POWER OPERATION
When the ignition switch is turned to the OFF position from ON or START position.
Power is supplied for 45 seconds

to main power window and door lock/unlock switch terminal 10

from BCM terminal 68.
When power and ground are supplied, the BCM continues to be energized, and the power window can be
operated.
The retained power operation is canceled when the front LH or front RH door is opened.
RAP signal period can be changed by CONSULT-II. Refer to GW-33, "
CONSULT-II Function (BCM)" .
ANTI-PINCH SYSTEM
Main power window and door lock/unlock switch, power window and door lock/unlock switch RH and rear
power window control unit LH and RH monitors the power window motor operation and the power window
position (full closed or other) for each power window by the signals from encoder and limit switch in power win-
dow motor.
When a window switch detects interruption during the following close operation,

automatic close operation when ignition switch is in the ON position

automatic close operation during retained power operation
Main power window and door lock/unlock switch, power window and door lock/unlock switch RH and rear
power window control unit LH and RH controls each power window motor for open and the power window will
be lowered about 150 mm (5.91 in).

POWER WINDOW CONTROL BY THE FRONT DOOR LOCK ASSEMBLY LH (KEY CYLINDER
SWITCH)
When ignition key switch is OFF, front power window LH and RH can be opened or closed by turning the front
door lock assembly LH (key cylinder switch) to the UNLOCK / LOCK position for more than 3 seconds.

Front power windows can be opened as the front door lock assembly LH (key cylinder switch) is kept fully
turned to the UNLOCK position.

Front power windows can be closed as the front door lock assembly LH (key cylinder switch) is kept fully
turned to the LOCK position.

While performing open/close operation for the windows, power window is stopped when the front door
lock assembly LH (key cylinder switch) is placed in the NEUTRAL position.

When the ignition switch is turned ON while the power window opening operation is performed, the power
window opening stops.
