PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000001548120

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 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 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 har-
ness connectors.

Precaution for Procedures Without Cowl Top Cover

INFOID:0000000001548121

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

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

INFOID:0000000001547383

WARNING:

• CFC-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

XX-XX, "*****"

. 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 oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If

oil other than that specified is used, compressor failure is likely to occur.

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

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 possible
to minimize the entry of moisture into system.

- Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without

proper sealing, oil will become moisture saturated and should not be used.

- Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.

Remove HFC-134a (R-134a) from the A/C system using certified service equipment meeting require-
ments of SAE J2210 [HFC-134a (R-134a) recycling equipment], or J2209 [HFC-134a (R-134a) recy-
cling equipment], If accidental system discharge occurs, ventilate work area before resuming
service. Additional health and safety information may be obtained from refrigerant and oil manufac-
turers.

< PRECAUTION >

[AUTO AIR CONDITIONER (W/NAVI)]

PRECAUTIONS

- Do not allow A/C oil 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, 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 refrigerant

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 available ser-
vice. 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.

• If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact NISSAN Cus-

tomer Affairs for further assistance.

Precaution for Service Equipment

INFOID:0000000001547384

MANIFOLD GAUGE SET

Be certain that the gauge face indicates R-134a or 134a. Make sure
the gauge set has 1/2

″

-16 ACME threaded connections for service

hoses. Confirm the set has been used only with refrigerant HFC-
134a (R-134a) along with specified oil.

SERVICE HOSES

Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.

SERVICE COUPLERS

Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
