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.

AUTO LIGHT OPERATION
Applicable lamps

Low beam headlamp

Parking, license plate and tail lamps

High beam headlamp (with the lighting switch in HIGH BEAM position)

Front fog lamp (with the lighting switch in front fog lamp ON position)
When the lighting switch is in AUTO position with the ignition switch in ON position, BCM detects the AUTO
LIGHT (ON) by BCM combination switch reading function. BCM turns automatically ON/OFF the applicable
lamps according to ambient brightness depending on the following condition.

It turns ON applicable lamps in 3 seconds when ambient brightness is less than 1250 lux.

This lighted lamps is turned OFF in 5 seconds when ambient brightness becomes 2500 lux or higher.
Releasing Function:

Turn ignition switch to the OFF position, or

Change lighting switch to the OFF, 1ST, 2ND position.
NOTE:
Timing for when lamps turn ON/OFF can be changed by the function setting of CONSULT-II. Refer to LT- 1 9 ,

CAN Communication System DescriptionBKS001O7
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.
CAN Communication UnitBKS001O8
Refer to LAN-49, "CAN System Specification Chart" .
Major Components and FunctionsBKS001O9
Components Functions
BCM

Turns ON/OFF circuits of parking lamp, license plate lamp, tail lamp and headlamp according to signals from
optical sensor, lighting switch (AUTO), and ignition switch (ON, OFF).
Optical sensor

Converts outside brightness (lux) to voltage, and sends it to BCM. (Detects brightness of 800 to 2500 lux)

CHASSIS AND BODY MAINTENANCE
(Annual Mileage <30,000 Km [18,000 miles]/year)
Abbreviations: I = Inspect and correct or replace as necessary, R = Replace
NOTE:

(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, inspect CVT fluid deterioration with
CONSULT-II every 90,000 km (54,000 miles), then change CVT fluid NS-2 if necessary. (Refer to CVT-46, "
Check CVT Fluid Dete-
rioration Date" .) And if CONSULT-II is not available, change (not just inspect) CVT fluid NS-2 every 90,000 km (54,000 miles).
Using transmission fluid other than Genuine Nissan CVT Fluid NS-2 will damage the CVT, which is not covered by the
warranty.

(2) Inspect once per year.

Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”. MAINTENANCE OPERATIONMAINTENANCE INTERVAL
