BREAK-IN OPERATION
When replacing compressor clutch assembly, always conduct the break-in operation. This is done by engag-
ing and disengaging the clutch about 30 times. Break-in operation raises the level of transmitted torque.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS006DM
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, 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 per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Brake SystemEFS005TG
lRecommended fluid is brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas.If brake fluid is splashed, wipe it off and flush area
with water immediately.
lNever use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
lUse flare nut wrench when removing flare nuts, and use a flare
nut torque wrench when tighten flare nuts.
lBrake system is an important safety part.If a brake fluid leak is
detected, always disassemble the affected part.If a malfunction
is detected, replace part with new one.
lBefore working, turn ignition switch OFF and disconnect con-
nector of ABS actuator and electric unit (control unit) or the bat-
tery cables.
lWhen installing brake tube and hose, be sure to torque.
WARNING:
Clean brake pads and shoes with a waster cloth, then wipe with
a dust collector.
Precautions for Brake ControlEFS005TH
lJust after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal status of operation check.
lStopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
lWhen an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and fluid leaks.
lIf tyre size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
lIf there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.
lIf aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

Removal and Installation
EBS01E6X
WARNING:
Do not remove radiator cap and/or reservoir tank cap when engine is hot. Serious burns could occur
from high pressure engine coolant escaping from radiator and/or reservoir tank.
REMOVAL
1. Remove front engine undercover and middle engine undercover. Refer toEI-15, "FRONT BUMPER".
2. Drain engine coolant from radiator drain plug at the bottom of radiator, and from water drain plug at the
side of cylinder block. Refer toCO-7, "
Changing Engine Coolant"andEM-110, "CYLINDER BLOCK".
CAUTION:
Perform this step when engine is cold.
3. Remove engine cover. Refer toEM-20, "
INTAKE MANIFOLD".
4. Disconnect radiator hoses (upper and lower) from engine side. Refer toCO-11, "
RADIATOR".
5. Remove air inlet pipe and air duct between air cleaner case and turbocharger. Refer toEM-15, "
AIR
CLEANER AND AIR DUCT"andEM-28, "TURBO CHARGER".
6. Remove water outlet, water inlet and thermostat.
7. Remove thermostat housing.
8. Disconnect heater return hose and water hoses at heater return pipe side, and remove heater return pipe.
9. Remove oil level gauge guide mounting bolt, vacuum hoses (to turbocharger boost control solenoid valve)
and spill hose. Refer toEM-36, "
OIL PAN AND OIL STRAINER",EM-20, "INTAKE MANIFOLD"andEM-
44, "INJECTION TUBE AND FUEL INJECTOR".
10. Disconnect water hoses (to EGR cooler) (A/T models), vacuum hoses and heater feed hose at heater
feed pipe side, and remove heater feed pipe. Refer toEM-20, "
INTAKE MANIFOLD".
INSPECTION AFTER REMOVAL
Thermostat
lPlace a string so that it is caught in the valves of the thermostat.
Immerse fully in a container filled with water. Heat while stirring.
lThe valve opening temperature is the temperature at which the
valve opens and falls from the thread.
lContinue heating. Check the full-open lift amount.
lAfter checking the full-open lift amount, lower the water temper-
ature and check the valve closing temperature.
Standard values
lIf out of the standard, replace thermostat.
INSTALLATION
Note the following, and install in the reverse order of removal.
lSecurely insert each hose, and install clamp at a position where it does not interfere with the pipe bulge.
lWhen inserting heater feed pipe end into cylinder head, apply a neutral detergent to O-ring. Then insert it
immediately.

System DescriptionEKS00MHA
OIL PRESSURE WARNING LAMP
Oil Pressure Warning
Oil pressure warning lamp turns ON when engine oil pressure reducing abnormally.
lIPDM E/R reads oil pressure switch signal from oil pressure switch, and transmits the signal to combina-
tion meter with CAN communication.
lCombination meter turns oil pressure warning lamp ON with received oil pressure switch signal.
Oil Level Warning
If engine oil level is 15 mm below low level of oil level gauge, oil level warning is detected.
Oil pressure warning lamp blinks and “OIL Lo” is displayed on odo/trip meter display, when oil level warning is
detected.
Oil level warning is displayed during ignition switch ON for 30 seconds after engine oil maintenance informa-
tion is displayed for 5 seconds.
lCombination meter reads oil level signal from oil level sensor.
lWhen combination meter judges oil level warning condition by oil level signal, oil level warning is dis-
played.
NOTE:
lOil level is gauged when the driver door is open.
lOil level is not gauged for 5 minutes after ignition switch OFF to wait oil falling down from cylinder head.
