Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000012857587

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 dual stage front air bag modules. The SRS system may only deploy
one front air bag, depending on the severity of a collision and whether the front passenger seat is occupied.
Information necessary to service the system safely is included in the SR 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, it is recommended that all mainte-
nance and repair be performed by an authorized NISSAN/INFINITI dealer.
• Improper repair, 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 SR 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 har-
ness connectors.
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 or batteries, and wait at least three minutes before performing any service.

Accelerator pedal stroke : Refer to ACC-7, "Acceler-

(A) ator Control"

• Check the accelerator pedal height.

Accelerator pedal height : Refer to ACC-7, "Acceler-

ator Control"
• Depress and release the accelerator pedal to check that it returns quickly and smoothly to the original
released position.
CAUTION:
• Whenever the harness connector of the accelerator pedal position sensor has been disconnected,
perform "Accelerator Pedal Released Position Learning". Refer to EC-701, "Description".
• The accelerator pedal should operate smoothly without catching when the pedal operating force is
released. The pedal should return smoothly to the fully raised position. The spring should be free
from damage.
