Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AJS001XF
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 Necessary for Steering Wheel Rotation After Battery DisconnectAJS001XG
NOTE:
This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
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 NVIS/IVIS, an electrically controlled steering lock
mechanism 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)AJS001XI
CAUTION:
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, 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.
–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.
–Never 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, take appropriate steps
shown below:
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 service equipment and refrigerant
supply.
Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
In case of repairing, recover the refrigerant using only dedicated equipment and containers. Never
recover contaminated refrigerant into the existing service equipment. If the facility does not have
dedicated recovery equipment, contact a local refrigerant product retailer for available service. This refrig-
erant 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.
If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact Nissan Cus-
tomer Affairs for further assistance.
General Refrigerant PrecautionsAJS001XJ
WARNING:
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 (125 °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.
