PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BJS000F1
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.
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 must be per-
formed by an authorized NISSAN/INFINITI 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 SRS section.

Do 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 and/or orange harnesses or
harness connectors.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectBJS000F2
NOTE:

This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT
SYSTEM).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.

Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precautions for Working with HFC-134a (R-134a)BJS000F4
CAUTION:

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 and compressor
malfunction is likely 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 malfunction 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:

ATC-6
PRECAUTIONS

–When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.
–When installing refrigerant components to a vehicle, never remove the caps (unseal) until just
before connecting the components. Connect all refrigerant loop components as quickly as possi-
ble to minimize the entry of moisture into system.
–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.
–Never allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrene foam parts.
Damage may result.
General Refrigerant PrecautionsBJS000F5
WARNING:

Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refriger-
ant. If accidental system discharge occurs, ventilate work area before resuming service. Addi-
tional health and safety information may be obtained from refrigerant and lubricant
manufacturers.

Never 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.

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: poisonous gas will be produced if refrigerant burns.

Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.

Never pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condition-
ing 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 refrigerant
manufacturers.
Precautions for Refrigerant ConnectionBJS000F7
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.

Expansion valve to evaporator

Refrigerant pressure sensor to condenser
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
connection 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 same way at it is when mounted on the car. Fail-
ure to do so will cause lubricant to enter the low-pressure chamber.

When connecting tubes, always use a torque wrench and a back-up wrench.

After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.

When installing an air conditioner in the vehicle, connect the pipes at the final stage of the opera-
tion. Never remove the seal caps of pipes and other components until just before required for con-
nection.

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 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 attached 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 until snug. 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.
Precautions for Servicing CompressorBJS000F8

Plug all openings to prevent moisture and foreign matter from entering.

When the compressor is removed, store it in the same position at it is when mounted on the car.

When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compres-
sor” exactly. Refer to AT C - 2 1 , "
Maintenance of Lubricant Quantity in Compressor" .

Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with lubri-
cant, 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.Lubricant name : Nissan A/C System Oil Type S
