• After installing plate clamps, apply force to them in the direction of the arrow, tightening rubber hose equally all around.
Engine OilsINFOID:0000000012433167
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
• Avoid prolonged and repeated contact with oils, particularly used engine oils.
• Wear protective clothing, including impervious gloves where practicable.
• Do not put oily rags in pockets.
• Avoid contaminating clothes, particularly underpants, with oil.
• Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.
• First aid treatment should be obtained immediately for open cuts and wounds.
• Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
• Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepara-
tions containing lanolin replace the natural skin oils which have been removed.
• Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
• If skin disorders develop, obtain medical advice without delay.
• Where practical, 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 addition an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste dis-
posal 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 sources.
The regulations concerning po llution vary between regions.
Air ConditioningINFOID:0000000012433168
Use an approved refrigerant recovery unit any time t he air conditioning system must be discharged. Refer to
HA-18, "

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012430709
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 severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the 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 Procedure without Cowl Top CoverINFOID:0000000012430710
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.
Precaution for WorkINFOID:0000000012430711
• When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusabl e part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
-Oily dirt:

HAC-4
< PRECAUTION >[MANUAL AIR CONDITIONING]
PRECAUTIONS
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty
area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.
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.
