4. Remove the mounting bolts on the front side of the front seat. (TORX bolt: T50)
5. Disconnect the harness connector under the seat and remove harness securing clips.
CAUTION:
Before removal, be sure to turn ignition switch OFF, disconnect both battery cables, and then wait
for at least 3 minutes.
6. Set seatback in a neutral position, and then remove front seat from the vehicle.
Installation
Install in the reverse order of removal. Be careful of the following three points.

Before the installation, confirm that the inside and outside slide rails are locked at the same positions.

Confirm that the slide rail location pin is set to the hole on the floor.

Clamp the harness in position.
Disassembly and AssemblyEIS0097M
SEAT CUSHION TRIM AND PAD
CAUTION:

Front passenger seat is equipped with an Occupant Classification System sensor and control
module. Do not disassemble front passenger seat cushion assembly or remove the trim as this
will affect the Occupant Classification System calibration.

During installation, the wire harness clips must be installed in the holes they were originally in. Do
not add additional clips.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EHS001XL
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.
WA RN ING:

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” ServiceEHS001XM

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.

The air bag 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.

Do not reuse center pillar upper garnish if removed.
Occupant Classification System PrecautionEHS001XN
Replace control unit and passenger front seat cushion as an assembly.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Revision: June 20062007 Versa
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)PFP:28556
SRS ConfigurationEHS001UR
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:
