FOR USA AND CANADA

FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR 
BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000009721063

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

Precaution for Procedure without Cowl Top Cover

INFOID:0000000009721065

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

Precautions for Removing of Battery Terminal

INFOID:0000000009944112

•  When removing the 12V battery terminal, turn OFF the ignition

switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur.

•  For vehicles with the 2-batteries, be sure to connect the main bat-

tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
detected.

•  After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:
The removal of 12V battery may cause a DTC detection error.

Working with HFC-134a (R-134a)

INFOID:0000000009721066

CAUTION:

• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. Compressor mal-

function is likely to occur if the refrigerants are mixed, refer to “CONTAMINATED REFRIGERANT”
below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refriger-
ant 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. Compressor malfunction is likely to occur if lubricant other than that specified is used.

• The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-

lowing handling precautions must be observed:

- Immediately cap (seal) immediately the component to minimize the entry of moisture from the atmo-

sphere when removing refrigerant components from a vehicle.

- Never remove the caps (unseal) until just before connecting the components when installing refrig-

erant components to a vehicle. Connect all refrigerant loop components as quickly as possible to
minimize the entry of moisture into system.

- Use only the specified lubricant from a sealed container. Immediately reseal containers of lubricant.

Lubricant becomes saturated with moisture and should not be used without proper sealing.

- Never allow lubricant (A/C System Oil Type S) to come in to contact with styrene foam parts. Damage

may result.

PRECAUTIONS

CONTAMINATED REFRIGERANT

Take the appropriate steps shown below if a refrigerant other than pure HFC-134a (R-134a) is identified
in a vehicle:
• 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 sup-

ply.

• Suggest the customer return the vehicle to the location of previous service where the contamination may

have occurred.

• If repairing, recover the refrigerant using only dedicated equipment and containers. Never reintroduce

contaminated refrigerant into the existing service equipment. Contact a local refrigerant product retailer
for available service if the facility does not have dedicated recovery equipment. This refrigerant must be dis-
posed of in accordance with all federal and local regulations. In addition, replacement of all refrigerant sys-
tem components on the vehicle is recommended.

• The air conditioner warranty is void if the vehicle is within the warranty period. Please contact Nissan Cus-

tomer Affairs for further assistance.

General Refrigerant Precaution

INFOID:0000000009721067

WARNING:

• Never breathe A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose or throat.

Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meeting require-
ments of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R-134a) recov-
ery equipment]. Ventilate the work area before resuming service if accidental system discharge
occurs. Additional health and safety information may be obtained from refrigerant and lubricant
manufacturers.

• Never release refrigerant into the air. Use approved recovery/recycling equipment to capture the

refrigerant each 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 (126

°

F).

• Never heat a refrigerant container with an open flame. Place the bottom of the container in a warm

pail of water if container warming is required.

• Never intentionally drop, puncture, or incinerate refrigerant containers.
• Keep refrigerant away from open flames. Poisonous gas is produced if refrigerant burns.
• Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo-

cation.

• Never pressure test or leakage test HFC-134a (R-134a) service equipment and/or vehicle air condi-

tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have proven 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 manu-
facturers.
