PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BHS0003U
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 per-
formed by an authorized NISSAN/INFINITI 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 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
harness connectors.
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceBHS0003V

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, and disconnect both battery cables. Then wait at least
3 minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.

Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformations or rust before
installation and replace if required.

The spiral cable must be set to the neutral position since its rotations are limited. Do not attempt to turn
steering wheel or column, if steering gear was disconnected from the column shaft.

Handle air bag module carefully. Always put a driver air bag module with the pad side facing upward.

Conduct self-diagnosis to check entire SRS for proper function after replacing any components.

After an air bag is deployed, the front instrument panel assembly should be replaced if damaged.

Always replace instrument panel pad following front passenger air bag deployment.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)PFP:28556
SRS ConfigurationBHS0003Z
The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the ON or START posi-
tion.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module and front passenger air bag module are activated in a frontal col-
lision but not in a side collision.
SRS configurations which are activated for some collision modes are as follows:

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

Front Seat Belt Pre-Tensioner with 2 Stage Load LimiterBHS00040
The seat belt pre-tensioner system with 2 stage load limiter is
installed for both the driver's seat and the front passenger's seat. It
operates simultaneously with the SRS air bag system in the event of
a frontal collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the pre-tensioner. Vehicle passengers are
securely restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the 2
stage load limiter permits the specified extension of the seat belt by
the twisting of the ELR shaft, and a relaxation of the chest-area seat
belt webbing tension while maintaining force.
