PRECAUTION
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000011677824
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.
WARNING:
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that 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 “SRS AIR BAG”.
• 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.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never 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.
Precautions for Removing Battery Terminal
INFOID:0000000011677832
• With the adoption of Auto ACC function, ACC power is automatically supplied by operating the intelligent key
or remote keyless entry or by opening/closing the driver side door. In addition, ACC power is supplied even
after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.
• When disconnecting the 12V battery terminal, turn off the ACC
power before disconnecting the 12V battery terminal, observing
“How to disconnect 12V battery terminal” described below.
NOTE:
Some ECUs operate for a certain fixed time even after ignition
switch is turned OFF and ignition power supply is stopped. If the
battery terminal is disconnected before ECU stops, accidental DTC
detection or ECU data damage may occur.
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.
HOW TO DISCONNECT 12V BATTERY TERMINAL
Disconnect 12V battery terminal according to instruction described below.
1.
Open the hood.
2.
Turn ignition switch to the ON position.
3.
Turn ignition switch to the OFF position with the driver side door opened.
4.
Get out of the vehicle and close the driver side door.

5.
Wait at least 3 minutes. For vehicle with the engine listed below, remove the battery terminal after a lapse
of the specified time.
CAUTION:
While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.
6.
Remove 12V battery terminal.
CAUTION:
After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.
Precautions Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000010478019
NOTE:
• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
• Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing work. If
a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.
OPERATION PROCEDURE
1.
Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2.
Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3.
Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4.
Perform the necessary repair operation.
5.
When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6.
Perform self-diagnosis check of all control units using CONSULT.

• The sonar sensor installed to the rear bumper detects obstacles around the bumper.
• The distance between a bumper and obstacles is informed to the driver with different frequency of buzzer.
Activation condition
The rear sensor activates and outputs the warning buzzer in the following conditions.
• Reverse signal ON (Power supply)
• Obstacle detection
Obstacle detection distance
• The sonar control unit controls the obstacle detection distance. The detection distance differs between the
corner sensor and the center sensor.
• Obstacle detection distance is indicated by a variable beep frequency.
Obstacle detection range image
NOTE:
• When an obstacle and distance of a bumper approach to less than 30 cm (11.8 in), a buzzer sound becomes a continuous sounds.
