+Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or
solvents for cleaning skin.
+If skin disorders develop, obtain medical advice without delay.
+Where practicable, degrease components prior to handling.
+Where there is a risk of eye contact, eye protection should be
worn, for example, chemical goggles or face shields; in addi-
tion an eye wash facility should be provided.
Environmental Protection PrecautionsNLGI0001S0702Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating sys-
tem must meet the requirements of HM Inspectorate of Pollution for
small burners of less than 0.4 MW. If in doubt, check with the
appropriate local authority and/or manufacturer of the approved
appliance.
Dispose of used oil and used oil filters through authorized waste
disposal contractors to licensed waste disposal sites, or to the
waste oil reclamation trade. If in doubt, contact the local authority
for advice on disposal facilities.
It is illegal to pour used oil on to the ground, down sewers or drains,
or into water courses.
The regulations concerning the pollution vary between
regions.
PRECAUTIONS FOR FUELNLGI0001S08Gasoline EngineNLGI0001S0804Models with three way catalyst
Unleaded premium gasoline of at least 95 octane (RON)
If premium gasoline is not available, unleaded regular gaso-
line with an octane rating of 91 (RON) may be temporarily
used, but only under the following precautions:
+Have the fuel tank filled only partially with unleaded regu-
lar gasoline, and fill up with premium unleaded gasoline
as soon as possible.
+Avoid full throttle driving and abrupt acceleration.
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Diesel Engine*:NLGI0001S0805Diesel fuel of at least 50 cetane
* If two types of diesel fuel are available, use summer or winter
fuel properly according to the following temperature conditions.
+Above 7°C (20°F) ... Summer type diesel fuel.
+Below 7°C (20°F) ... Winter type diesel fuel.
CAUTION:
+Do not use home heating oil, gasoline, or other alternate
fuels in your diesel engine. The use of those can cause
engine damage.
+Do not use summer fuel at temperatures below 7°C
(20°F). The cold temperatures will cause wax to form in the
fuel. As a result, it may prevent the engine from running
smoothly.
+Do not add gasoline or other alternate fuels to diesel fuel.
PRECAUTIONS FOR AIR CONDITIONINGNLGI0001S09Use an approved refrigerant recovery unit any time the air condi-
tioning system must be discharged. Refer to HA-85, “HFC-134a

Supplemental Restraint System (SRS) “AIR
BAG” and “SEAT BELT PRE-TENSIONER”
NLHA0190The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS system composition which is available to NISSAN MODEL V10 is as follows (The compo-
sition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat
belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal
collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
+To 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 should be per-
formed by an authorized NISSAN dealer.
+Improper 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 RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions for Working with HFC-134a
(R-134a)
NLHA0113WARNING:
+CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. These refrigerants
must never be mixed, even in the smallest amounts. If the refrigerants are mixed, compressor fail-
ure is likely to occur.
+Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-
nents. If lubricant other than that specified is used, compressor failure is likely to occur.
+The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-
lowing handling precautions must be observed:
a) When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.
b) When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just
before connecting the components. Connect all refrigerant loop components as quickly as pos-
sible to minimize the entry of moisture into system.
c) Only use the specified lubricant from a sealed container. Immediately reseal containers of lubri-
cant. Without proper sealing, lubricant will become moisture saturated and should not be used.
d) Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose
and throat. Remove R-134a from the A/C system, using certified service equipment meeting
requirements of R-134a recycling equipment, or R-134a recovery equipment. If accidental system
discharge occurs, ventilate work area before resuming service. Additional health and safety
information may be obtained from refrigerant and lubricant manufacturers.
e) Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts.
Damage may result.
General Refrigerant PrecautionsNLHA0114WARNING:
+Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
+Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
PRECAUTIONS
Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
HA-2

+When installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.
+Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
+Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
+Always replace used O-rings.
+When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
Lubricant name: Nissan A/C System Oil Type R for DKV-11G compressor
Part number: KLH00-PAGR0
Lubricant name: Nissan A/C System Oil Type S for CSV613 compressor
Part number: KLH00-PAGS0
+O-ring must be closely attached to dented portion of tube.
+When replacing the O-ring, be careful not to damage O-ring and tube.
+Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.
+After connecting line, conduct leak test and make sure that there is no leakage from connections.
When the gas leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.
RHA861F
Precautions for Servicing CompressorNLHA0116+Plug all openings to prevent moisture and foreign matter from entering.
+When the compressor is removed, store it in the same position as it is when mounted on the car.
+When replacing or repairing compressor, follow“Maintenance of Lubricant Quantity in Compres-
sor”exactly. Refer to HA-87.
+Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with
lubricant, wipe it off by using a clean waste cloth moistened with thinner.
+After compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.
+After replacing the compressor magnet clutch, apply voltage to the new one and check for normal
operation.
