Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

EKS009IX

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 and SB section of
this Service Manual.

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.

NATS AUDIO LINK
Description

The link with the NATS IMMU implies that the audio unit can basically only be operated if connected to the
matching NATS IMMU to which the audio unit was initially fitted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted theft of the audio unit is basically
useless since special equipment is required to reset the audio unit.
Initialization process for audio units that are linked to the NATS IMMU

●

Perform initialization with CONSULT-II

●

For initialization, refer to “CONSULT-II operation manual NATS”.

Normal operation
Each time the audio unit is switched on afterwards, the audio unit code will be verified between the audio unit
and the NATS before the audio unit becomes operational.
When the radio is locked
When NATS link problems occur “SECURE” message will be displayed in three ways indicating three different
NATS link problems.
“Secure” on a red background indicates that there is a problem in the link between NAVI control unit and
Audio, suggesting that there is either a Navigation system fault or the NAVI control unit has previously been fit-
ted in another vehicle.
“Secure” on a green background indicates that there is a problem in the link between NATS IMMU and Audio,
suggesting that there is an audio fault or the audio unit has previously been fitted in another vehicle.
“Secure” on a yellow background indicates that the transponder (NATS key) is not working correctly or it has
previously been fitted in another vehicle.
When a “Secure” message (of any type) is displayed, it can be cleared by re-initializing the NATS system
using CONSULT-II and the associated Immobilizer PIN code (there is no need to return the audio to a Clarion
service centre). If re-initializing fails to clear a “Secure” message then the component (identified by back-
ground color) is faulty and should be replaced.

SPEED DEPENDENT VOLUME CONTROL
Description

If activated, the radio output volume will be automatically adjusted to compensate for increased driving noises
at higher driving speeds.
The radio receives a speed signal from the combination meter and selects the output volume.

PERSONAL AUDIO SETTINGS
Description

The radio is designed to store several settings (volume, bass, treble, preset stations and level of speed depen-
dent volume control) with every NATS ignition key used. Up to a maximum of 4 NATS keys can be registered.
During the communication mentioned under “Anti-Theft System”, the radio will recognize the used ignition key

and select the accompanying settings.

Transferring radio to another vehicle/
replacement of radio by an “old” part

Radio needs to be reset by using CON-
SULT-II and the associated Immobilizer
PIN code (there is no need to return the
audio or NAVI units to a Clarion service
centre).

—

Replacement of IMMU

The communication between IMMU and
radio need to be reset by using CONSULT-
II and the associated Immobilizer PIN
code.

After switching on the radio, it will display
“SECURE” on a green background.

No communication from IMMU to radio

1. If NATS is malfunctioning, check NATS

system.

2. After NATS is repaired, reset radio to

“Secure” on a green background state
by using CONSULT-II and the associ-
ated Immobilizer PIN code (there is no
need to return the audio to a Clarion ser-
vice centre).

After switching on the radio, the display
unit will display “SECURE” on a green
background. Further use of radio is impos-
sible until communication is established
again, or after radio is reset by using CON-
SULT-II and the associated Immobilizer
PIN code (there is no need to return the
audio to a Clarion service centre).
