Precaution for Supplemental Restraint S
ystem (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006226734
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether 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:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.
 Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
 When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT 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 minu tes before performing any service.
General PrecautionsINFOID:0000000006226735
Turn ignition switch OFF an d disconnect the battery cable
from the negative terminal before connecting or disconnect-
ing the A/T assembly connector. Because battery voltage is
applied to TCM even if igniti on switch is turned OFF.
 Perform “DTC (Diagnostic Trouble Code) CONFIRMATION
PROCEDURE” after performing each TROUBLE DIAGNOSIS.
If the repair is completed DTC should not be displayed in the
“DTC CONFIRMATION PROCEDURE”.
 Always use the specified brand of ATF. Refer to MA-10, "
Fluids
and Lubricants".
 Use lint-free paper not cloth rags during work.
 Dispose of the waste oil using the methods prescribed by law, ordi-
nance, etc. after replacing the ATF.
 Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
