TOW TRUCK TOWINGPFP:00000
Tow Truck TowingBAS0007V
CAUTION:

All applicable local laws regarding the towing operation
must be obeyed.

It is necessary to use proper towing equipment to avoid
possible damage to the vehicle during towing operation.
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 power train are in good order. If any unit is
damaged, dollies must be used.
NISSAN recommends that the vehicle be towed with the driving
(front) wheels off the ground as illustrated.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH THE FRONT WHEELS ON THE GROUND
CAUTION:
Never tow an automatic transaxle model with the front wheels on the ground as this will cause serious
and expensive damage to the transaxle.
Vehicle Recovery (Freeing a Stuck Vehicle) BAS0007W

Always pull the cable straight out from the front or rear of the
vehicle. Never pull on the vehicle at an angle.

Remove the front spoiler when you pull the vehicle forward. Oth-
erwise, the towing device may damage the spoiler.

Pulling devices such as ropes or canvas straps are not recom-
mended for use in vehicle towing or recovery.

Use the recovery hooks only, not other parts of the vehicle. Oth-
erwise, the vehicle body will be damaged.

Use the recovery hooks only to free a vehicle stuck in sand,
snow, mud, etc. Never tow the vehicle for a long distance using
only the recovery hooks.

The recovery hooks are under tremendous force when used to
free a stuck vehicle.

Stand clear of a stuck vehicle.

CAN Communication System DescriptionBKS0041K
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

Notes on Steering Angle Sensor (Neutral Point) Adjustment

Be sure to adjust steering angle sensor to the neutral point before driving if any of the followings is
removed/installed or replaced: AFS control unit; Steering angle sensor; Steering system part, Suspension
system part.

Steering angle sensor neutral point adjustment should be performed by using CONSULT-II. (The adjust-
ment is not operative without CONSULT-II.)
Operation Procedure (with VDC)
Perform steering angle sensor neutral point adjustment only on VDC side. Never perform the adjustment on
ADAPTIVE LIGHT side as this may lead to VDC malfunctions. If the adjustment has been performed on AFS
side, readjust on VDC side. For steering angle sensor neutral point adjustment procedures on VDC side, refer
to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" in “ON-VEHICLE SERVICE”.
