PRECAUTION
PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951676
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 t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 mi nutes before performing any service.
Precaution for Draining CoolantINFOID:0000000009460515
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000009460516
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000009460517
• When instructed to use special service tools, use the spec ified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equiva lent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized 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
opposite, and so on. If the order of loosening is specif ied, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000009460518
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000009460519
• Use torque wrench to tighten bolts or nuts to specification.

COMPRESSION PRESSURE
COMPRESSION PRESSURE
On-Vehicle ServiceINFOID:0000000009460536
CHECKING COMPRESSION PRESSURE
1. Run the engine until it reaches normal operating temperature.
2. Turn the ignition switch to OFF.
3. Release fuel pressure and leave t he fuel pump electrically disconnected.
Refer to EC-687, "Work Procedure"
.
4. Remove all six spark plugs. Refer to EM-132, "Removal and Installation"
.
5. Install the compression tester with the adapter into the spark plug hole. • Use compression tester whose end (a) (rubber portion) is
smaller than 20 mm (0.79 in) in diameter. Otherwise, it may be
caught by cylinder head during removal.
6. Depress accelerator pedal fully to keep the electric throttle control actuator butterfly-valve wide open to
maximize air intake flow.
7. Crank the engine and record the highest gauge indication.
8. Repeat the measurement on each cylinder (steps 5 - 7). NOTE:
Always use a fully charged battery to obtain specified engine speed.
Unit: kPa (kg/cm2, psi)/rpm
9. If compression in one or more cylinders is low:
a. Pour a small amount of engine oil into cylinders through the spark plug holes.
b. Retest compression (steps 5 - 8).
• If adding oil helps raise compression pressure, then the piston rings may be worn or damaged. If so, replace piston rings after checking piston.
• If the pressure stays low, a valve may be sticking or is seating improperly. Inspect and repair the valve and/
or valve seat. Refer to EM-212, "Inspection After Disassembly"
. If the valve and/or valve seat is damaged
replace as necessary.
• If compression stays low in two or more cylinders that are next to each other:
- The cylinder head gasket may be leaking.
- Both cylinders may have valve component damage. Inspect and repair as necessary.
