PRECAUTIONS

PFP:00001

Description

NAS0004K

Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

NAS0004L

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.

WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Precautions for NVIS/IVIS (NISSAN/INFINITI VEHICLE IMMOBILIZER SYSTEM - 
NATS) (If Equipped)

NAS0004M

NVIS/IVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS/IVIS
(NATS).
Both of the originally supplied ignition key IDs have been NVIS/IVIS (NATS) registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NVIS/IVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.

When NVIS/IVIS (NATS) detects trouble, the security indicator lamp lights up while ignition switch is in
"ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.

When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
other NVIS/IVIS (NATS) ignition key IDs), CONSULT-II hardware and CONSULT-II NVIS/IVIS (NATS)
software is necessary.
Regarding the procedures of NVIS/IVIS (NATS) initialization and NVIS/IVIS (NATS) ignition key ID regis-
tration, refer to CONSULT-II operation manual, NVIS/IVIS (NATS).

Therefore, CONSULT-II NVIS/IVIS (NATS) software (program card and operation manual) must be kept
strictly confidential to maintain the integrity of the anti-theft function.

When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
other NVIS/IVIS (NATS) ignition key IDs), it may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A maximum of four or five key IDs can be regis-
tered into NVIS/IVIS (NATS).

When failing to start the engine first time using the key of NVIS/IVIS (NATS), start as follows.

1.

Leave the ignition key in "ON" position for approximately 5 seconds.

2.

Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.

3.

Repeat step 1 and 2 again.

4.

Restart the engine while keeping the key separate from any others on key-chain.

PRECAUTIONS

Revision: 2006 August

2006 Murano

Precautions Necessary for Steering Wheel Rotation After Battery Disconnect

NAS0005T

NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the

LOCK

 position.

Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.

OPERATION PROCEDURE

1.

Connect both battery cables.

NOTE:
Supply power using jumper cables if battery is discharged.

2.

Use the Intelligent Key or mechanical key to turn the ignition switch to the 

ACC

 position. At this time, the

steering lock will be released.

3.

Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.

4.

Perform the necessary repair operation.

5.

When the repair work is completed, return the ignition switch to the 

LOCK

 position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

6.

Perform a self-diagnosis check of all control units using CONSULT-II. 

Precautions for Procedures without Cowl Top Cover

NAS0005U

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

General Precautions

NAS0004O

Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any flam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to
properly ventilate the area before working with hazardous mate-
rials.
Do not smoke while working on the vehicle.

Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.

When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.

Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.

If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.

Battery posts, terminals and related accessories contain lead
and lead compounds. Wash hands after handling.

To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.

Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.

Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.

Replace inner and outer races of tapered roller bearings and needle bearings as a set.

Arrange the disassembled parts in accordance with their assembled locations and sequence.

Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.

After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

Use only the fluids and lubricants specified in this manual.

Use approved bonding agent, sealants or their equivalents when required.

Use hand tools, power tools (disassembly only) and recom-
mended special tools where specified for safe and efficient ser-
vice repairs.

When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.

PRECAUTIONS

Revision: 2006 August

2006 Murano

Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.

WARNING:

To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.

Precautions for Three Way Catalyst

NAS0004P

If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.

Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.

When checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.

Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to
the catalyst.

Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.

Precautions for Fuel (Unleaded Premium Gasoline Recommended)

NAS0004Q

Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).

For improved vehicle performance, NISSAN/INFINITI recommend the use of unleaded premium gasoline with
an octane rating of at least 91 AKI number (Research octane number 96).

CAUTION:

Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.

Precautions for Multiport Fuel Injection System or Engine Control System

NAS0004R

Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.

Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.

Be careful not to jar components such as ECM and mass air
flow sensor.

HOSE REMOVAL AND INSTALLATION

To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.

To reinstall the rubber hose securely, make sure that hose inser-
tion length and orientation is correct. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)

HOSE CLAMPING

If old rubber hose is re-used, install hose clamp in its original
position (at the indentation where the old clamp was). If there is
a trace of tube bulging left on the old rubber hose, align rubber
hose at that position. 

Discard old clamps; replace with new ones.

After installing plate clamps, apply force to them in the direction
of the arrow, tightening rubber hose equally all around.

PRECAUTIONS

Revision: 2006 August

2006 Murano

Wear protective clothing, including impervious gloves where practicable.

Do not put oily rags in pockets.

Avoid contaminating clothes, particularly underpants, with oil.

Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.

First aid treatment should be obtained immediately for open cuts and wounds.

Use barrier creams, applying them before each work period, to help the removal of oil from the skin.

Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepa-
rations containing lanolin replace the natural skin oils which have been removed.

Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.

If skin disorders develop, obtain medical advice without delay.

Where practical, degrease components prior to handling.

Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.

Precautions for Air Conditioning 

NAS0004U

Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to
ATC/MTC section “HFC-134a (R-134a) Service Procedure”, “REFRIGERANT LINES” for specific instructions.
