PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS000C3
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 Battery ServiceNKS000C4
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

AudioPilot® System
AudioPilot® is the sound improving system that picks up by a microphone under the steering any noises or the
sound of music coming into the vehicle, and that uses the BOSE speaker amp. to revise the frequency feature
of music in real time in response to the frequency feature of the noise while driving and listening to music.

If low frequency area noise from vehicle is loud, it adjusts low frequency element of music to be bigger
than vehicle noise.

If high frequency area noise from vehicle is loud, it adjusts high frequency element of music to be bigger
than vehicle noise.

If vehicle noise is smaller than the setting volume, correction is not performed.
