PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" AJS001FF
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:
q 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.
q 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.
q 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 Battery Service AJS000S7
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Precautions for Procedures without Cowl Top Cover AJS001XP
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

PRECAUTIONS
Precautions for Working with HFC-134a (R-134a) AJS0009G
A
WARNING:
q 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 B
Refrigerant Recovery/Recycling Recharging equipment and Refrigerant Identifier.
q 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. C
q The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-
lowing handling precautions must be observed:
