• Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs.
• When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
• Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic trou ble codes, do not carelessly disconnect the harness
connectors which are related to the engine cont rol 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 TM sections.
Three Way CatalystINFOID:0000000012433163
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
• Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
• When checking for ignition spark or measuring engine compression, make tests quickly and only when nec-
essary.
• Do 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.
FuelINFOID:0000000012433164
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
CAUTION:
• Using a fuel other than that specified could adversely affect th e emission control system, and may
also affect the warranty coverage.
• Under no circumstances should a leaded gasoline be used, because this will damage the three-way
catalyst.
• Do not use E-15 or E-85 fuel in your vehicle. Your vehicle is not designed to run on E-15 or E-85 fuel. Using E-15 or E-85 fuel in a vehicle not specifically designed for E-15 or E-85 fuel can adversely
affect the emission control devices and systems of the vehicle. Damage caused by such fuel is not
covered by the NISSAN new vehicle limited warranty.
• Do not use fuel that contains the octane boo ster methylcyclopentadienyl manganese tricarbonyl
(MMT). Using fuel containing MM T may adversely affect vehicle pe rformance and vehicle emissions.
Not all fuel dispensers are labeled to indicate MMT content, so you may have to consult your gaso-
line retailer for more details. Note that Federal and California laws prohibit the use of MMT in refor-
mulated gasoline.

Precautions For Refrigerant System ServiceINFOID:0000000012430712
GENERAL REFRIGERANT PRECAUTION
WARNING:
• Do not breathe A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. Venti-
late work area before resuming service if accidental system discharge occurs. Additional health and
safety information may be obtained fr om refrigerant and oil manufacturers.
• Do not release refrigerant into the air. Use ap proved recovery/recycling recharging equipment to
capture the refrigerant each time an air conditioning system is discharged.
• Wear always eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
• Do not store or heat refrigerant containers above 52 °C (126° F).
• Do not heat a refrigerant container with an open fl ame. Place the bottom of the container in a pail of
warm water if container warming is required.
• Do not intentionally drop, puncture, or incinerate refrigerant containers.
• Keep refrigerant away from open flames. Pois onous gas is produced if refrigerant burns.
• Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo- cation.
• Do not pressure test or leakage test HFC-134a (R- 134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause
injury or property damage. Additional health and safety information may be obtained from refriger-
ant manufacturers.
WORKING WITH HFC-134a (R-134a)
CAUTION:
• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) re frigerant are not compatible. These refrigerants
must never be mixed, even in the smallest amount s. Compressor malfunction is likely occur if the
refrigerants are mixed.
• Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components.
Compressor malfunction is likely to occur if oil other than that specified is used.
• The specified HFC-134a (R-134a) oi l rapidly absorbs moisture from the atmosphere. The following
handling precautions must be observed:
- Cap (seal) immediately the component to minimize the entry of mo isture from the atmosphere when
removing refrigerant components from a vehicle.
- Do not remove the caps (unseal) unti l just before connecting the components when installing refrig-
erant components to a vehicle. Connect all refr igerant loop components as quickly as possible to
minimize the entry of moisture into system.
- Use only the specified oil from a sealed container. Reseal immediately containers of oil. Oil becomes
moisture saturated and should no t be used without proper sealing.
- Do not allow oil (A/C System Oil Type: DH-PR) to come in contact with styrene foam parts. Damage
may result.
REFRIGERANT CONNECTION
A new type refrigerant connection has been introduced to al l refrigerant lines except the following location.
• Expansion valve to evaporator
• Refrigerant pressure sensor to liquid tank
WARNING:
Check that all refrigerant is disch arged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loo sen the discharge side hose fitting and remove it.
CAUTION:
Observe the following when replacing or cleaning refrigerant cycle components.

Trouble Diagnosis For Unusual PressureINFOID:0000000012431994
Diagnose using a manifold gauge set whenever refrigerant pressures are unusual. The marker above the
gauge scale in the following table indicates the standard (usual) pressure range. Refer to HA-24, "
Inspection".
Symptom TableINFOID:0000000012431995
Gauge indicationRefrigerant cycleProbable causeCorrective action
Both high and low-pressure sides
are too high. The pressure returns to nor-
mal soon after sprinkling wa-
ter on condenser.
Overfilled refrigerant. Recover refrigerant, evacuate
system, and recharge with the
specified amount of refrigerant.
Refer to HA-20, "
Recycle Re-
frigerant".
Air flow to condenser is insuf-
ficient. Insufficient condenser cooling
performance.
• Poor cooling fan rotation.
• Missing and/or improper in-
stallation of air guides.
• Clogged or dirty condenser fins. • Repair or replace malfunc-
tioning parts.
• Clean and/or repair condens- er fins.
When compressor stops,
high-pressure gauge quickly
drops by approximately 196
kPa (2 kg/cm
2, 28 psi), then
gradually decreases. Air mixed with refrigerant.
Recover refrigerant, evacuate
system, and recharge with the
specified amount of refrigerant.
Refer to HA-20, "Recycle Re-
frigerant".
• Low-pressure pipe is cooler than the outlet of evapora-
tor.
• Low-pressure pipe is frost- ed. Expansion valve opened too
much (excessive flow of refrig-
erant).
Replace expansion valve. Refer
to
HA-36, "
EXPANSION VALVE
: Removal and Installation".
High-pressure side is excessively
high and low-pressure side is too
low. High-pressure pipe and upper
side of condenser become
hot, however, liquid tank does
not become so hot.Clogged or crushed high-pres-
sure pipe located between
compressor and condenser.
Repair or replace the malfunc-
tioning parts.
High-pressure side is too low and
low-pressure side is too high. • The readings of both sides
become equal soon after
compressor stops.
• There is no temperature dif-
ference between high and
low-pressure sides. Malfunctioning compressor (in-
sufficient compressor pressure
operation).
• Damaged or broken of inter-
nal components.
• Malfunctioning gaskets. Replace compressor. Refer to
