Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003960542
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 AIRBAG” and
“SEAT BELT” 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 performed by
an authorized NISSAN/INFINITI dealer.
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 AIRBAG”.
Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
Precaution for Trouble DiagnosisINFOID:0000000003882788
AV COMMUNICATION SYSTEM
Do not apply voltage of 7.0 V or higher to the measurement terminals.
Use the tester with its open terminal voltage being 7.0 V or less.
Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before
checking the circuit.
Precaution for Harness RepairINFOID:0000000003882789
AV COMMUNICATION SYSTEM
Solder the repaired parts, and wrap with tape. [Frays of twisted line
must be within 110 mm (4.33 in).]
Do not perform bypass wire connections for the repair parts. (The
spliced wire will become separated and the characteristics of
twisted line will be lost.)

3. Rotate the center dial, and then select the guiding line pattern so
that its angle is aligned with the correction line of the rear of the
vehicle.
4. Fine adjust the guiding line so that its position is aligned to the
correction line by pressing the up/down/left/right switches.
Pressing “ENTER” enable the camera control unit to memory
the adjusted guiding line position.
CAUTION:
Never operate other function such as pressing BACK while writing index data.
If Confirmation/Adjustment mode does not function in the above procedure, perform one of the
following service to adjust the index again.
Remove battery for five min. Then reconnect battery.
Remove camera control unit connector for five min. Then reconnect camera control unit connec-
tor.Selected pattern : 7
