Precautions for Service EquipmentEJS000T6
RECOVERY/RECYCLING EQUIPMENT
Be certain to follow the manufacturers instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.
ELECTRONIC LEAK DETECTOR
Be certain to follow the manufacturer's instructions for tester operation and tester maintenance.
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pres-
sure. So the vacuum pump lubricant may migrate out of the pump
into the service hose. This is possible when the pump is switched off
after evacuation (vacuuming) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as follows.
lUsually vacuum pumps have a manual isolator valve as part of
the pump. Close this valve to isolate the service hose from the
pump.
lFor pumps without an isolator, use a hose equipped with a man-
ual shut-off valve near the pump end. Close the valve to isolate
the hose from the pump.
lIf the hose has an automatic shut off valve, disconnect the hose
from the pump. As long as the hose is connected, the valve is
open and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under a no vacuum condition. Such valves may restrict the pump's
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
Be certain that the gauge face indicates R-134a or 134a. Be sure the
gauge set has 1/2²-16 ACME threaded connections for service
hoses. Confirm the set has been used only with refrigerant HFC-
134a (R-134a) and specified lubricants.

WA RN ING:
lBefore removing and installing components and harnesses of SRS air bag and seat belt pre-ten-
sioner system, turn ignition switch OFF, disconnect battery ground cable, and wait at least 3 min-
utes. (This discharges electricity held in the air bag sensor unit's additional power circuit.)
lDo not use pneumatic or electric tools to remove and install the components.
lDo not solder SRS air bag and seat belt pre-tensioner system harnesses when making repairs.
Make sure harness is not pinched and there is no contact with other components.
lWhen checking the SRS air bag and the seat belt pre-tensioner circuit or the components of each
system, do not use an electric tester such as a circuit tester. (This is to prevent accidental trigger-
ing caused by the weak electric current of a tester.)
lNever insert foreign material (such as a screwdriver) in the air bag module and pre-tensioner seat
belt connectors. (The units may be actuated by mistake by static electricity.)
lSeat belt pre-tensioner and SRS air bag harnesses can be distinguished from other harnesses by
their yellow connectors.
lWhen servicing, refer to “SB Seat Belt” and “SRS Air Bag” for safety.
Precautions for Brake SystemEFS000BZ

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS0019N
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.
WAR NIN G:
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 harness connector.

Procedure".
WAR NIN G:
Clean brakes with a vacuum dust collector to minimize risk
of health hazard from powder caused by friction.
Precautions for Brake ControlEFS0019P
lDuring the EPS/TCS/ABS operation, the brake pedal vibrates lightly and its mechanical noise may be
heard. This is a normal condition.
lJust after starting the vehicle after ignition switch ON, the brake pedal may vibrate or the motor operating
noise may be heard from the engine compartment. This is a normal status of the operation check.
lThe stopping distance may be longer than that of vehicles without ABS when the vehicle drives on rough,
gravel, or snowy (fresh deep snow) road.
lIf a malfunction is indicated by the ABS warning lamp, or other warning lamps, collect the necessary infor-
mation from the customer (what symptoms are present under what conditions) and find out the possible
causes before starting the service. Besides the electrical system inspection, check the booster operation,
brake fluid level, and oil leaks.
lIf the tire size and type are used in a improper combination, or the brake pads are not NISSAN genuine
parts, the stopping distance or steering stability may deteriorate.
lIf there is a radio, antenna, or antenna lead-in wire (including wiring) near the control unit, the ESP/TCS/
ABS function may have a malfunction or error.
lIf aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check the electrical har-
nesses for pinches, open, and improper wiring.

WA RN ING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precautions for All Mode 4´4 SystemEAS000GQ
Even if the 2WD mode is selected, the All mode 4´4 system occasionally changes from 2WD to 4WD auto-
matically depending on the driving conditions.
When spinning the front wheels by running the engine with the front wheels jacked up or mounted on the free
rollers / or a chassis dynamometer, be careful because the vehicle may suddenly move due to the driving
force from the rear wheels.
To avoid personal injury and vehicle damage, use one of the following methods when working with the front
wheels drive force and spinning freely.
lRemove the propeller shaft.
lUse free rollers / chassis dynamometer designed for 4WD vehicles.
Precautions for Three Way CatalystEAS000FR
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
lUse unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
lWhen checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.
lDo not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to
the catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precautions for FuelEAS000FS
Use unleaded gasoline with an octane rating of at least 95 (RON).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
