●Use approved bonding agent, sealants or their equivalents when required.
●Use tools and recommended special tools where specified for safe and efficient service repairs.
●When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
●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 All Mode 4 × 4 SystemEAS000GQ
Even if the 2WD mode is selected, the All mode 4 × 4 system occasionally changes from 2WD to 4WD auto-
matically depending on the driving conditions.
When spinning the front wheels by running the engine with the front wheels jacked up or mounted on the free
rollers / or a chassis dynamometer, be careful because the vehicle may suddenly move due to the driving
force from the rear wheels.
To avoid personal injury and vehicle damage, use one of the following methods when working with the front
wheels drive force and spinning freely.
● Remove the propeller shaft.
● Use free rollers / chassis dynamometer designed for 4WD vehicles.
Precautions for Three Way CatalystEAS000FR
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 FuelEAS000P9
GASOLINE ENGINE
Use unleaded gasoline with an octane rating of at least 95 (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.

How to Perform Efficient Diagnosis for an Electrical IncidentEAS000G6
WORK FLOW
INCIDENT SIMULATION TESTS
Introduction
Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The fol-
lowing section illustrates ways to simulate the conditions/environment under which the owner experiences an
electrical incident.
The section is broken into the six following topics:
●Vehicle vibration
SGI838
STEP DESCRIPTION
STEP 1Get 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:
WHATVehicle Model, Engine, Transmission/Transaxle and the System (i.e. Radio).
WHENDate, Time of Day, Weather Conditions, Frequency.
WHERERoad Conditions, Altitude and Traffic Situation.
HOWSystem Symptoms, Operating Conditions (Other Components Interaction).
Service History and if any After Market Accessories have been installed.
STEP 2Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem cannot be duplicated, refer to “Incident Simulation Tests”.
STEP 3Get 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 4Inspect 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
Layouts.
STEP 5 Repair or replace the incident circuit or component.
STEP 6Operate 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.

Special Service Tools EAS000FH
CAUTION:
●Every time the vehicle is lifted up, maintain the complete vehicle curb condition.
●Since the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up point on the rear side garage jack with a mission
jack or equivalent.
●Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the front side garage jack with a mission jack or
equivalent.
●Be careful not to smash or do not do anything that would affect piping parts.
Garage Jack and Safety Stand EAS000FI
WARNING:
●Park the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes,
tubes, etc. under the vehicle.
●Never get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.

Tow Truck TowingEAS000FL
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.
●Never tow an automatic transmission model from the rear (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
NISSAN recommends that towing dollies be used when towing your
vehicle beplaced on a flat bed truck as illustrated.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH FOUR WHEELS ON GROUND
Observe the following restricted towing speeds and distances.
CAUTION:
Never tow an automatic transaxle model from the rear (i.e., backward) with four wheels on the ground
as this may cause serious and expensive damage to the transaxle.
