CAUTION:
 All applicable local laws regarding the towing operation must be obeyed.
 It is necessary to use proper towi ng equipment to avoid possible damage to the vehicle during tow-
ing operation. To wing is in accordance with Towing Procedure Manual at dealer.
 Always attach safety chains before towing.
 When towing, check that the transmission, steering syst em and powertrain are in good order. If any
unit is damaged, dollies must be used.
 Never tow automatic transmission model from the rear (that is backward) with four wheels on the
ground. This may cause serious and exp ensive damage to the transmission.
4WD MODELS
NISSAN recommends that a dolly be used as illustrated when towing 4WD models.
CAUTION:
Never tow 4WD models with any of the wheels on the ground as this may cause serious and expensive
damage to the powertrain.
Vehicle Recovery (Freeing a Stuck Vehicle)INFOID:0000000006280881
FREEING TRAPPED VEHICLE
WARNING:
 Stand clear of a stuck vehicle.
 Never allow anyone to stand near the towing line during the pulling operation.
 Never spin your tires at high sp eed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.
CAUTION:
 Tow chains or cables must be attached only to the vehicle recovery hooks or main structural mem-
bers of the vehicle. Otherwise, the vehicle body will be damaged.
 Never use the vehicle tie downs to free a vehicle st uck in sand, snow, mud, etc. Never tow the vehi-
cle using the vehicle tie downs or recovery hooks.
 Always pull the cable straight out from the front of the vehicle. Never pull on the hook at an angle.

 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 ar e not recommended for use in vehicle towing or
recovery.
 In order to not break the towi ng line, tension it slowly.

AUTOMATIC TRANSMISSION
To tow a vehicle equipped with an automatic tr ansmission, an appropriate vehicle dolly MUST be placed under
the towed vehicle's drive wheels. Always follow the dolly manufacture's recommendations when using their
product.
If the vehicle is stuck in sand, snow , mud, etc., use the following procedure:
1. Turn off the Vehicle Dynam ic Control System. (if equipped)
2. Check the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward. Shift back and forth between R (reverse) and D (drive).
Apply the accelerator as little as possible to maintain the rocking motion.
Release the accelerator pedal before shifting between R and D.
Do not spin the tires above 35 mph. (55 km/h).
5. If the vehicle can not be freed after a few tries, cont act a professional towing service to remove the vehi-
cle.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000006275903
CAN (Controller Area Network) is a serial communication
system for real time application. It is an on-vehicle
multiplex communication system with high data comm unication speed and excellent error detection ability.
Many electronic control units are equipped onto vehicl es, and each control unit shares information and links
with other control units during operation (not independent ). In CAN communication, control units are con-
nected with two communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/recei ves data but selectively reads required data only.
CAN Communication Signal Chart. Refer to LAN-28, "

tion Signal Chart".

NOTE:
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts i
f found
damaged or if the auto belt tensioner reading reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000
km) or 60 months. Use only Genu ine NISSAN Long Life Antifreeze/Coo lant (blue) or equivalent with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water will reduce the life
expectancy of the factory-fill coolant.
(5) Periodic maintenance is not required. However, if valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perfo rm
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.

*1: For further details, see “Engine Oil Recommendation”.
*2: Using automatic transmission fluid other than Genuine NISSAN Matic S ATF will cause deterioration in driveability and autom atic
transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited wa rranty.
*3: DEXRON™ VI type ATF may also be used.
*4: Available in mainland U.S.A. through an INFINITI dealer.
*5: Using transfer fluid other t han Genuine NISSAN Transfer Fluid will damage the transfer , which is not covered by the INFINITI new
vehicle limited warranty. See an INFINITI retailer for recommended transfer fluid.
*6: For hot climates, Viscosity SAE 90 is suitable for ambient temperatures above 0 °C (32 °F)
*7: See an INFINITI dealer for service for synthetic oil.
*8: Using Hydraulic Suspen sion fluid other than Genuine NISSAN Hydraulic Susp ension fluid will damage the Hydraulic Suspension,
which is not covered by the INFINITI new vehicle limited warranty. See an INFINITI retailer for recommended hydraulic suspensio n fluid.
*9: The fluid capacity is the reference value.
Engine Oil RecommendationINFOID:0000000006287732
NISSAN recommends the use of an energy conservi ng oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubri-
cant Standardization and Approval Committee (ILSAC) ce rtification and SAE viscosity standard. These oils
have the API certification mark on t he front of the container. Oils which do not have the specified quality label
should not be used as they could cause engine damage.

The TCM becomes the protection control status temporar ily to protect the safety when the safety of TCM and
transmission is lost. It automatically returns to the normal status if the safety is secured.
The TCM has the following protection control.
REVERSE INHIBIT CONTROL
Intercepts the torque transmission and shift to the neutral stat us if the selector lever is shifted to “R” position
while the vehicle moves forward at the vehicle speed 10 km/h (7 MPH) or more.
1ST ENGINE BRAKE PROTECTION CONTROL
Controls the engine brake so as not to make effective by turning the front brake solenoid output to OFF when
each solenoid becomes the electricity pattern of 1st engine brake during driving at the vehicle speed 25 km/h
or more in any positions other than “R” position and 1GR.
TCM HIGH TEMPERATURE PROTECTION CONTROL
Limit the accelerator opening and forcibly control the vehi cle to the low torque driving when the electronic sub-
strate in TCM reaches the high temperature.
