Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006410247
The Supplemental Restraint System such as “A IR 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 w hether 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 inopera tive, 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 unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005929596
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK ″ position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
4. Perform the necessary repair operation.

1. Disconnect the negative and positive battery term inals, then wait at least three minutes.
2. Remove the rear leg covers.
3. Remove the front leg covers.
4. Remove the mounting bolts on the back si de of the front seat. (TORX bolt: T50)
5. Remove the mounting bolts on the front side of the front seat. (TORX bolt: T50)
6. Disconnect the harness connector under the seat and remove harness securing clips.
7. Set seatback in a neutral position, and t hen remove front seat from the vehicle.
Installation
Installation is 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.

CAUTION:
• Front passenger seat is equipped with an Occupant Classification System sensor and control mod-
ule. Do not disassemble front passenger seat cushion assembly or remove the trim as this will affect
the Occupant Classificatio n System calibration.
• During installation, the wire harn ess clips must be installed in the holes they were originally in. Do
not add additional clips.
1. Remove the seat from the vehicle. Refer to SE-12, "
Removal and Installation".
2. Remove the seat recline and lift levers.

Precaution for SRS "AIR BAG" and "S EAT BELT PRE-TENSIONER" Service
INFOID:0000000006211105
• Do not use electrical test equipment to check SRS ci rcuits 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 SR S 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.

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:
