Removal and InstallationEIS00C62
REMOVAL
When removing or installing the seat trim, handle it carefully to keep dirt out and avoid damage.
CAUTION:
lBefore removing the front seat, turn the ignition switch off, disconnect both battery cables and
wait at least 3 minutes.
lWhen checking the power seat circuit for continuity using a circuit tester, do not confuse its con-
nector with the side air bag module connector. Such an error may cause the air bag to deploy.
lDo not drop, tilt, or bump the side air bag module while installing the seat. Always handle it with
care.
lAfter front side air bag module inflates, front seatback assembly must be replaced.
1. Slide the seat backward, and then remove the seat slide cover
cap(1) and rear leg cover(2), and then remove the seat mount-
ing bolts.
2. Slide the seat forward, and then open the seat slide cover
cap(1) and remove the front leg cover(2), and then remove the
seat mounting bolts.
NOTE:
If disassembling the seat after removal, set the front/rear cush-
ion lifters to the top position.
3. Disconnect both battery cables and wait at least 3 minutes.
4. Disconnect the side air bag module harness connector.
5. Disconnect the power seat harness connectors and remove the seat from the vehicle.
NOTE:
When removing and installing the seat, use shop cloths to protect the vehicle from damage.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EHS001Y8
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:
lTo 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.
lImproper 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.
lDo 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” ServiceEHS001Y9
lDo not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
lBefore 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 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.
lDiagnosis sensor unit must always be installed with their arrow marks “Ü” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before instal-
lation and replace as required.
lThe 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.
lHandle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and place front side air bag module standing with stud bolt side setting bottom.
lConduct self-diagnosis to check entire SRS for proper function after replacing any components.
lAfter air bag inflates, the front instrument panel assembly should be replaced if damaged.
lAlways replace instrument panel pad following front passenger air bag deployment.
Precautions for Trouble DiagnosisEHS001YA
When you read wiring diagrams, refer to the following:
lGI-15, "How to Read Wiring Diagrams"in GI section
lPG-4, "POWER SUPPLY ROUTING CIRCUIT"in PG section
When you perform trouble diagnosis, refer to the following:
lGI-11, "How to Follow Trouble Diagnoses"in GI section
lGI-24, "How to Perform Efficient Diagnosis for an Electrical Incident"in GI section
Check for any service bulletins before servicing the vehicle.

SRS ConfigurationEHS001XA
The air bag deploys if the air bag diagnosis sensor unit is activated while the ignition switch is in the ON or
START position.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-tension-
ers are activated in a frontal collision but not in a side collision.
SRS configurations for some collision modes are as follows:

Front Seat Belt Pre-Tensioner with Load LimiterEHS001XB
The seat belt pre-tensioner system with 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
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
web tension while maintaining force.
Front Side Air BagEHS001XC
Front side air bag modules are built into the front seatback assemblies.
Vehicles with side air bags are equipped with labels as shown.
Side Curtain Air BagEHS001XD
Side curtain air bag modules are located above the vehicle headlining.
Vehicles with side curtain air bags are equipped with labels as
