• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner dr ops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

- 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.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951691
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.
General PrecautionINFOID:0000000009460597
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the work area.
• Be sure to work in a well ventilated area and have a CO
2 fire extinguisher.
• Do not smoke while working on the fuel system. Keep open flames and sparks away from the work
area.
CAUTION:
• Before removing fuel line parts, carry out the following procedures:
- Put drained fuel in an explosi on-proof container and put the lid on securely. Keep the container in
safe area.
- Release fuel pressure from the fuel lines. Refer to EC-182, "Work Procedure"
(QR25DE), EC-687,
"Work Procedure" (VQ35DE).
- Disconnect the battery ground cable.
• Always replace O-rings and clamps with new ones.
• Do not kink or twist tubes when they are being installed.
• Do not tighten hose clamps excessi vely to avoid damaging hoses.
Tighten high-pressure rubber hose clamp so that clamp end
is 3 mm (0.12 in) from hose end.
Tightening torque specificati ons are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.

• After connecting the fuel tu
be quick connectors, make sure
the quick connectors are secure.
Check that the connector and r esin tube do not contact any
adjacent parts.
- a) Apply fuel pressure to the fu el system by turning the igni-
tion switch to ON (without star ting the engine). Then check for
fuel leaks at the fuel tube connections.
- b) Start the engine and rev the engine, then check for fuel leaks at the fuel tube connections.
• After installing the tubes, run the engine and check for fuel
leaks at the connections.
• Use only a Genuine NISSAN fuel filler cap as a replacement. If
an incorrect fuel fi ller cap is used, the MIL may come on.
• For servicing “Evaporative Emi ssion System” parts, refer to
EC-62, "EVAPORATIVE EMISSI ON SYSTEM : System Descrip-
tion" (QR25DE for California), EC-62, "EVAPORATIVE EMIS-
SION SYSTEM : System Description" (QR25DE except for
California), EC-580, "EVAPORATIVE EM ISSION SYSTEM : Sys-
tem Description" (VQ35DE).
• For servicing “On Board Refuel ing Vapor Recovery (ORVR)”
parts, refer to EC-39, "On Board Refueling Vapor Recovery
(ORVR)" (QR25DE for California), EC-39, "On Board Refueling
Vapor Recovery (ORVR)" (QR25DE except for California), EC-
564, "On Board Refueling Vapor Recovery (ORVR)" (VQ35DE).PBIC0199E
