REMOVAL
When removing or installing the seat trim, carefully handle it to keep dirt out and avoid damage.
CAUTION:

Before removing the front seat, turn ignition switch OFF, disconnect both battery cables and wait
at least 3 minutes.

When 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.

Do not drop, tilt, or bump the side air bag module installing in the seat. Always handle it with care.
1. Remove the seat cushion outer finisher cover.
2. Remove the front seat belt anchor bolt. Refer to SB-4, "
Removal
and Installation of Front Seat Belt" .
CAUTION:
Set the front and rear cushion lifter to the down position.
3. Remove the screw.
4. Remove the seat cushion forward finisher lid.
5. Remove the seat cushion forward finisher.
6. Remove the seat slide and lifter switch knob (1) and seat reclin- ing switch knob (2).

vehicle, and pull up to remove.

Slide the seat forward, then disengage the tabs on the front
LH and RH of the rear leg cover and tabs engaged into the
rail. Then pull the cover toward the rear of the vehicle.
11. Slide the seat until the body mounting bolts are visible and a tool can be inserted. NOTE:
When disassembling the driver seat after removal, set the front and rear cushion lifter to the top position.
12. Disconnect both battery cables.
13. Remove the harness connector for the side air bag module.
14. Remove the power seat harness connector and vehicle harness fixing clip.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NHS00073
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 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” ServiceNHS00074

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 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, deformities or rust before instal-
lation and replace as required.

The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steer-
ing wheel and 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.

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

Disposal, recycling, and transportation of air bag modules and seat belt pre-tensioners should be per-
formed in compliance with applicable federal, state and local laws and regulations.
Occupant Classification System PrecautionNHS0009N
Replace occupant classification system control unit and passenger front seat cushion as an assembly.
