< PRECAUTION >
PRECAUTIONS
Before jacking up the vehicle, apply wheel chocks or other tireblocks to the wheels to prevent t he vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
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.
To prevent serious burns: Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
Dispose of 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 com ponents which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
After disconnecting vacuum or air hoses, atta ch 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 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 leakage.

TOW TRUCK TOWING
TOW TRUCK TOWING
Tow Truck TowingINFOID:0000000006280880
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.

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. check you have not inadvertently
created a new incident during your diagnosis or repair steps.
