FUEL INJECTION TIMING
Two types of systems are used.
• Sequential Multiport Fuel Injection System
Fuel is injected into each cylinder during each engine cycle according to the ignition order. This system is
used when the engine is running.
• Simultaneous Multiport Fuel Injection System
Fuel is injected simultaneously into all six cylinders twice each engine cycle. In other words, pulse signals of
the same width are simultaneously transmitted from the ECM.
The six injectors will then receive the signals 2 times for each engine cycle.
This system is used when the engine is being started and/or if the fail-safe system (CPU) is operating.
FUEL SHUT-OFF
Fuel to each cylinder is cut off during deceleration, operation of the engine at excessively high speeds or oper-
ation of the vehicle at excessively high speeds.

PRE-TENSIONER"
INFOID:0000000009951675
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
Precaution for Draining CoolantINFOID:0000000009460453
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000009460454
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before any removal or disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000009460455
• When instructed to use special service tools, use the s pecified tools. Always be careful to work safely, avoid
forceful operations.
• Use maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or equivalent , if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organi zed way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally

FRONT FOG LAMP
FRONT FOG LAMP
Aiming AdjustmentINFOID:0000000009463618
PREPARATION BEFORE ADJUSTING
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment procedure, check the following:
• Ensure all tires are inflated to correct pressure.
• Place vehicle and screen on level surface.
• Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
• Coolant and engine oil filled to correct level, and fuel tank full.
• Remove cargo and/or luggage to maintain an unloaded vehicle condition.
• Confirm spare tire, jack and tools are properly stowed.
• Carefully wipe off any dirt from headlamp lens. CAUTION:
Do not use organic solvent (thinner, gasoline etc.)
• Place a driver or equivalent weight of 68.5 kg (150 lb) on the driver seat.
• By hand, bounce the front and rear of the vehicle to settle the suspension and eliminate any static load.
• Place the front tires in the straight ahead position.
• Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
NOTE:
• For headlamp aiming details, refer to regulations in your area.
• By regulation, no means for horizontal aim adjustment is provided from the factory; only vertical aim is
adjustable.
• Use adjusting screw to perform aiming adjustment.
• Perform headlamp aiming if:
- The vehicle front body has been repaired.
- The front combination lamp has been removed or replaced.
- Any outfitting has been installed.
- The vehicle’s standard load condition has been substantially increased.
Aiming Adjustment Procedure
1. Place the screen. NOTE:
• Stop the vehicle facing the wall.
• Place the board on a plain road vertically.
2. Face the vehicle with the screen. Maintain 7.62 m (25.0 ft) between the front fog lamp center and the
screen.
3. Start the engine. Turn the front fog lamp ON. NOTE:
Shut off the headlamp light with the board to prevent from illuminating the adjustment screen.
CAUTION:
Do not cover the lens surface with a tape etc. The lens is made of resin.
4. Adjust aiming in the vertical direction by turning the adjusting screw (A).

General PrecautionsINFOID:0000000009460620
• When installing rubber bushings, the final tightening mu st be carried out under unladen conditions with tires
on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
- Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions.
• After servicing suspension parts, be sure to check wheel alignment.
• Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-oiled,
tighten as they are.
Precaution for Procedure without Cowl Top CoverINFOID:0000000009460621
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to

LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between upper link and steering knuckle.
3. Measure axial end play by prying it up and down.Refer to FSU-26, "Ball Joint"
.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.

Check for oil leakage, damage and repl ace if malfunction is detected.
WHEEL ALIGNMENT
Description
Measure wheel alignment under unladen conditions.
NOTE:
"Unladen conditions" means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
General Information and Recommendations
• A four-wheel thrust alignment should be performed.
- This type of alignment is re commended for any NISSAN vehicle.
- The four-wheel "thrust" process helps ensure that t he vehicle is properly aligned and the steering wheel is
centered.
- The alignment rack itself should be capable of accepting any NISSAN vehicle.
- The rack should be checked to ensure that it is level.
• Make sure the machine is properly calibrated.
- Your alignment equipment should be regularly ca librated in order to give correct information.
- Check with the manufacturer of your specific equi pment for their recommended Service/Calibration Sched-
ule.
Preliminary Check
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-60, "Road Wheel"
.
3. Wheel bearing axial end play. Refer to FAX-27, "Wheel Bearing"
.
4. Transverse link ball joint axial end play. Refer to FSU-11, "Removal and Installation"
.
5. Shock absorber operation.
6. Each mounting part of axle and suspension for looseness and deformation.
7. Each of suspension member, shock absorber, upper link and transverse link for cracks, deformation and other damage.
8. Vehicle height (posture).
Alignment Process
IMPORTANT:
Use only the alignment specificati ons listed in this Service Manual.
• When displaying the alignment settings, m any alignment machines use "indicators" Do not use these indi-
cators. : (Green/red, plus or minus, Go/No Go).
- The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.
