Nissan Pathfinder (2008 year). Manual - part 419

GI-40

< PRECAUTION >

PRECAUTIONS

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

Precaution for Fuel

INFOID:0000000001665377

GASOLINE ENGINE

Use unleaded gasoline with an octane rating of at least 91 (RON).

CAUTION:

Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.

DIESEL ENGINE

Diesel fuel of at least 50 cetane.
If two types of diesel fuel are available, use summer or winter fuel properly according to the following temper-
ature conditions.
• Above –7

°

C (20

°

F) ... Summer type diesel fuel.

• Below –7

°

C (20

°

F) ... Winter type diesel fuel.

CAUTION:

• Do not use home heating oil, gasoline or other alternate fuels in your diesel engine. The use of those

can cause engine damage.

• Do not use summer fuel at temperatures below –7

°

C (20

°

F). The cold temperatures will cause wax to

form in the fuel. As a result, it may prevent the engine from running smoothly.

• Do not add gasoline or other alternate fuels to diesel fuel.

Precaution for Multiport Fuel Injection System or Engine Control System

INFOID:0000000001665378

• 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 injec-

tors, be sure to release fuel pressure.

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

sensor.

Precaution for Turbocharger (If Equipped)

INFOID:0000000001665379

The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean sup-
ply of oil flowing through the turbocharger and to follow all required
maintenance instructions and operating procedures.
• Always use the recommended oil. Follow the instructions for

proper time to change the oil and proper oil level.

• Avoid accelerating engine to a high rpm immediately after starting.
• If engine had been operating at high rpm for an extended period of

time, let it idle for a few minutes prior to shutting if off.

Precaution for Hoses

• 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 insertion

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 posi-

tion (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.

Precaution for Engine Oils

INFOID:0000000001665381

Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.

HEALTH PROTECTION PRECAUTIONS 

• Avoid prolonged and repeated contact with oils, particularly used engine oils.
• Wear protective clothing, including impervious gloves where practicable.
• Do not put oily rags in pockets.
• Avoid contaminating clothes, particularly underpants, with oil.

< PRECAUTION >

PRECAUTIONS

• 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). Prepara-

tions 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.

Precaution for Air Conditioning

INFOID:0000000001665382

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.

WARNING:

• Never get under the vehicle while it is supported only by the jack. Always use safety stands to sup-

port the frame when you have to get under the vehicle.

• Place wheel chocks at both front and back of the wheels on the ground.

CAUTION:

• All applicable local laws regarding the towing operation must be obeyed.
• It is necessary to use proper towing equipment to avoid possible damage 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 powertrain are in good order. If

any unit is damaged, dollies must be used.

• Never tow an automatic transmission model from the rear

(i.e., backward) with four wheels on the ground as this may
cause serious and expensive damage to the transmission.

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 trans-
fer 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.

Observe the following restricted towing speeds and distances.

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)

INFOID:0000000001665408

• Tow chains or cables must be attached only to the main structural members of the vehicle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or

cooling systems

• Always pull the cable straight out from the front or rear of the vehicle. Never pull the vehicle at a

sideways angle.

• Pulling devices such as ropes or canvas straps are not recommended for use for vehicle towing or

recovery.

STEP

DESCRIPTION

STEP 1

Get detailed information about the conditions and the environment when the incident occurred.
The following are key pieces of information required to make a good analysis:

WHAT

Vehicle Model, Engine, Transmission/Transaxle and the System (i.e. Radio).

WHEN

Date, Time of Day, Weather Conditions, Frequency.

WHERE

Road Conditions, Altitude and Traffic Situation.

HOW

System Symptoms, Operating Conditions (Other Components Interaction). 
Service History and if any After Market Accessories have been installed. 

STEP 2

Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem cannot be duplicated, refer to “Incident Simulation Tests”.

STEP 3

Get the proper diagnosis materials together including:
• Power Supply Routing
• System Operation Descriptions
• Applicable Service Manual Sections
• Check for any Service Bulletins
Identify where to begin diagnosis based upon your knowledge of the system operation and the customer comments.

STEP 4

Inspect the system for mechanical binding, loose connectors or wiring damage.
Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness Lay-
outs.

STEP 5

Repair or replace the incident circuit or component.

STEP 6

Operate the system in all modes. Verify the system works properly under all conditions. Make sure you have not inad-
vertently created a new incident during your diagnosis or repair steps.
