Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EJS001QX
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 for Working with HFC-134a (R-134a) EJS001A7
WARNING:
● CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants
are mixed and compressor failure is likely to occur. Refer to MTC-3, "
Contaminated Refrigerant" .
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 failure 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 R-134a from the A/C system, using certified service equipment meeting require-
ments of SAE J2210 (R-134a recycling equipment), or J2209 (R-134a recovery equipment). If acci-
dental 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 A/C lubricant to come in contact with styrofoam parts. Damage may result.
Contaminated Refrigerant EJS001A8
If a refrigerant other than pure 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.
● If you choose to perform the repair, recover the refrigerant using only dedicated equipment and contain-
ers. Do not recover contaminated refrigerant into your existing service equipment. If your facility
does not have dedicated recovery equipment, you may contact a local refrigerant product retailer for avail-
able service. This refrigerant must be disposed of in accordance with all federal and local regulations. In
addition, replacement of all refrigerant system components on the vehicle is recommended.
