belt NISSAN PATROL 2006 Owner's Guide

Observe the following precautions to ensure safe and proper
servicing. These precautions are not described in each indi-
vidual section.
Precaution for Supplemental Restraint System
(SRS) ``AIR BAG'' and ``SEAT BELT
PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and
``SEAT BELT PRE-TENSIONER'' used along with a seat belt, helps
to reduce the risk or severity of injury to the driver and front pas-
senger in a frontal collision. The SRS system composition which is
available to NISSAN MODEL Y61 is as follows (The composition
varies according to the destination.):
Driver air bag module (located in the center of the steering wheel),
front passenger air bag module (located on the instrument panel on
passenger side), seat belt pre-tensioner, a diagnosis sensor unit,
warning lamp, wiring harness and spiral cable.
Information necessary to service the system safely is included in
theRS sectionof 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 in¯ation, all main-
tenance must be performed by an authorized NISSAN
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 RS section.
+Do not use electrical test equipment on any circuit related
to the SRS unless instructed to in this Service Manual.
Spiral cable and wiring harnesses are covered with yellow
insulation either just before the harness connectors or for
the complete harness are related to the SRS.

Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The composition var-
ies according to the destination.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof 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 in¯ation, all maintenance must be performed
by an authorized NISSAN 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 RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation either just before
the harness connectors or for the complete harness are related to the SRS.
Precautions for Working with HFC-134a
(R-134a)
WARNING:
+CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. These refriger-
ants must never be mixed, even in the smallest amounts. If the refrigerants are mixed, compres-
sor failure is likely to occur.
+Use only speci®ed lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) com-
ponents. If lubricant other than that speci®ed is used, compressor failure is likely to occur.
+The speci®ed HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The
following handling precautions must be observed:
a: When removing refrigerant components from a vehicle, immediately cap (seal) the component
to minimize the entry of moisture from the atmosphere.
b: 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.
c: Only use the speci®ed lubricant from a sealed container. Immediately reseal containers of
lubricant. Without proper sealing, lubricant will become moisture saturated and should not
be used.
d: Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose
and throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a)
refrigerant. If accidental system discharge occurs, ventilate work area before resuming ser-
vice. Additional health and safety information may be obtained from refrigerant and lubricant
manufacturers.
e: Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam
parts. Damage may result.
