PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003532849
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 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 SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000003532850
• Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bags and seat belt
pre-tensioners to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
• The air diagnosis sensor unit must always be installed with the arrow mark “⇐” pointing toward the front of
the vehicle for proper operation. Also check air bag diagnosis sensor unit for cracks, deformities or rust
before installation and replace as required.
• The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
• Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side
facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.
• Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
• After air bag inflates, the front instrument panel assembly should be replaced if damaged.
Occupant Classification System PrecautionINFOID:0000000003532851
Replace control unit and passenger front seat cushion as an assembly.

REMOVAL
CAUTION:
• Do not attempt to repair or replace damaged direct-connect SRS component connectors. If a driver
air bag direct-connect harness connector is damaged, the spiral cable must be replaced.
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least
3 minutes.
• When servicing the SRS, do not work from directly in front of air bag module.
1. Disconnect the negative and positive battery cables, then wait at least 3 minutes.
2. Remove the left and right side lids and bolts.
3. Lift the driver air bag module from the steering wheel.
4. Disconnect the horn connector and air bag harness, then remove the driver air bag module.
• For removal/installation of the direct-connect SRS connectors, refer to SRS-6, "
Direct-connect SRS
Component Connectors" .
CAUTION:
• When servicing the SRS, do not work from directly in front of air bag module.
• Always place air bag module with pad side facing upward.
• Do not insert any foreign objects (screwdriver, etc.) into air
bag module or harness connectors.
• Do not disassemble air bag module.
• Do not use old bolts after removal; replace with new bolts.
• Do not expose the air bag module to temperatures exceeding
90°C (194°F).
