PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
A
B
INFOID:0000000006753028
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 AIR BAG” and
“SEAT BELT” of this Service Manual.
The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.
C
D
E
F
G
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 performed by
an authorized NISSAN/INFINITI dealer.
SRC
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.
I
• 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 har-
ness connectors.
• The vehicle may be equipped with a passenger air bag deactivation switch which can be operated by
J
the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled and
will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled and
could inflate for certain types of collision. After SRS maintenance or repair, make sure the passenger
air bag deactivation switch is in the same position (ON or OFF) as when the vehicle arrived for ser-
K
vice.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, DO NOT use air or electric 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 minutes before performing any service.

N
Service
INFOID:0000000006439846
• Never use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect battery negative terminal and wait 3 minutes
or more.
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, never 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 installa-
tion and replace as required.
• The spiral cable must be aligned with the neutral position since its rotations are limited. Never turn steering
wheel and column after removal of steering gear.
