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 al l control units using CONSULT-III.
Procedures without Cowl Top CoverINFOID:0000000003771198
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
General PrecautionsINFOID:0000000003771199
• 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 inflammable
materials. Special care should be taken when handling any inflam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or ot her enclosed area, be sure to prop-
erly ventilate the area before working with hazardous materials.
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 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.

PRECAUTIONS
• 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 leaks.
• Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic tro uble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)

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 an d back of the wheels on the ground.
CAUTION:
• All applicable State or Provincial (in Canada) laws and 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 wh eels on the ground as this may
cause serious and expensive dama ge to the transmission.
2WD MODEL
NIFINTI 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: Turn the
ignition key to the OFF posit ion and move the transmission
selector lever to N (neutral) pos ition, turn the ignition key to
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.
• When the battery of the vehicle equipped with Intelligent Key system is discharged, the vehicle should be towed with the
front wheels on towing dollies or place the vehicle on a flat
bed truck.

INIFINTI recommends that towing dollies be used when towing 4WD
equipped vehicles or place the vehicle on a flat bed truck.
CAUTION:
• Never tow 4WD models with any of the wheels on the ground as this may cause serious and expensive damage to the
transfer case and transmission.
Towing Point
CAUTION:
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:0000000005867508
•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.
