1. As shown in the right figure illustration, use a drift [commercial
service tool φ22mm (0.87in)] to drive manual shaft oil seals into
the transmission case until it is flush.
CAUTION:

Apply ATF to manual shaft oil seals.

Do not reuse manual shaft oil seals.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AJS001BM
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. 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 whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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 for Working with HFC-134a (R-134a)AJS0013V
WARNING:

CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants
are mixed and compressor malfunction is likely to occur, refer to “CONTAMINATED REFRIGER-
ANT” below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use
Refrigerant Recovery/Recycling Recharging equipment and Refrigerant Identifier.

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:
–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, do not 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.
–Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meet-
ing requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (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.
–Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts.
Damage may result.
CONTAMINATED REFRIGERANT
If a refrigerant other than pure HFC-134a ( R-134a) is identified in a vehicle, your options are:

Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant
into the atmosphere.

Explain that recovery of the contaminated refrigerant could damage your service equipment and refriger-
ant supply.

Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
