 Never release refrigerant into the air. Use appr oved recovery/recycling equipment to capture the
refrigerant every time an air co nditioning system is discharged.
 Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
 Never store or heat refrigerant containers above 52 °C (126 °F).
 Never heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.
 Never intentionally drop, puncture, or incinerate refrigerant containers.
 Keep refrigerant away from open flames: poison ous gas will be produced if refrigerant burns.
 Refrigerant will displace oxygen, therefore be certa in to work in well ventilated areas to prevent suf-
focation.
 Never pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air conditioning
systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a) have been
shown to be combustible at elevat ed pressures. These mixtures, if ig nited, may cause injury or prop-
erty damage. Additional health a nd safety information may be obtain ed from refrigerant manufactur-
ers.
Precaution for Refrigerant ConnectionINFOID:0000000001328155
A new type refrigerant connection has been introduced to a ll refrigerant lines except the following location.

ABOUT ONE-TOUCH JOINT
Description
 One-touch joints are pipe joints which do not require tools during piping connection.
 Unlike conventional connection methods using union nuts and flanges, controlling tightening torque at con-
nection point is not necessary.
 When removing a pipe joint, use a disconnector.

CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
 When the compressor is removed, store it in the sam e way at it is when mounted on the car. Failure
to do so will cause lubricant to enter the low-pressure chamber.
 When connecting tubes, always use a to rque wrench and a back-up wrench.
 After disconnecting tubes, immediately plug all op enings to prevent entry of dust and moisture.
 When installing an air conditioner in the vehicle, connect the pipes at the final stage of the operation.
Never remove the seal caps of pipes and other compon ents 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 refriger ation system before charging the refrigerant.
 Always replace used O-rings.
 When connecting tubes, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
 O-ring must be closely att ached to the groove of tube.
 When replacing the O-ring, be careful not to damage O-ring and tube.
 Connect tube until a click can be heard, then tighten the nut or bolt by hand. Make sure that the O-
ring is installed to tube correctly.
 After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.
Precaution for Service of CompressorINFOID:0000000001328156
 Plug all openings to prevent moisture and foreign matter from entering.
 When the compressor is removed, store it in th e same way at it is when mounted on the car.
 When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compressor”
exactly. Refer to ATC-22, "
Maintenance of Lubricant Quantity in Compressor".
 Keep friction surfaces between clut ch and pulley clean. If the surface is contaminated with lubricant,
wipe it off by using a clean w aste cloth moistened with thinner.
 After compressor service operation, turn the compr essor shaft by hand more than five turns in both
directions. This will equally dist ribute 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, ap ply voltage to the new one and check for normal
operation.

Break-in Operation
When replacing compressor clutch assembly, always carry out break-in operation. This is done by engaging
and disengaging clutch about thirty-times. Break-in oper ation raises the level of transmitted torque.

 When straightening body panels, use caution in pulling any HSS panel. Because HSS is very strong, pulling may cause
deformation in adjacent portions of the body. In this case,
increase the number of measuring points, and carefully pull
the HSS panel.
 When cutting HSS panels, avoid gas (torch) cutting if possible. Instead, use a saw to avoid weakening surrounding areas due
to heat. If gas (torch) cutting is unavoidable, allow a minimum
margin of 50 mm (1.97in).
 When welding HSS panels, use spot welding whenever possi- ble in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use M.I.G. welding. Do not use
gas (torch) welding because it is inferior in welding strength.
 The spot weld on HSS panels is harder than that of an ordi- nary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a low
speed high torque drill (1,000 to 1,200 rpm) to increase drill bit
durability and facilitate the operation.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612918
The Supplemental Restraint System such as “A IR 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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t 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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001612920
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake SystemINFOID:0000000001327604
 Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
 Recommended fluid is brake fluid “DOT 3”. MA-9, "
Fluids and Lubricants".
 Do not reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas.
 To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
 Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
 Use a flare nut crowfoot and torque wrench when installing brake
tube.
 When installing brake piping, be sure to check torque.
 Before working, turn ignition switch OFF and disconnect connec- tors for ABS actuator and electric unit (control unit) or battery neg-
ative terminal.
 Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to BR-23, "
Brake Burnishing Procedure" (Front disc brake),
BR-29, "
Brake Burnishing Procedure" (Rear disc brake).
WARNING:
 Clean brake pads and shoes with a waste cl oth, then clean with a dust collector.
