Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EJS001H4
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 may include seat belt switch inputs and dual stage front air bag modules. If
equipped with 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 Manual.
The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.
WARNING:
â—ŹTo 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.
â—ŹImproper 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.
â—ŹDo 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.
â—ŹThe vehicle may be equipped with a passenger air bag deactivation switch which can be operated
by the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled
and will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled
and could inflate for certain types of collision. After SRS maintenance or repair, make sure the
passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehicle
arrived for service.
Precautions for Working with HFC-134a (R-134a)
EJS0010Z
WARNING:
â—ŹCFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants
are mixed, compressor failure is likely to occur. Refer to MTC-4, "Contaminated Refrigerant" . To
determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refrigerant
Recovery/Recycling Recharging equipment (ACR4) (J-39500–NI) and Refrigerant Identifier.
â—ŹUse 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.
â—ŹThe 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-
