PRECAUTIONS FOR USE OF THE AROUND VIEW MONITOR WITH PARK ASSIST

• Around view monitor with Park Assist is designed to support the driver’s steering wheel operation in a park-

ing lot. It does not automatically lower the vehicle speed or avoid contact with objects. As when performing
ordinary parking maneuvers, always look out the windows and check with own eyes to be sure that the sur-
rounding and road conditions are safe for the maneuvers before operating the vehicle. Operate the vehicle
slowly during the parking maneuvers. If the vehicle gets close to people or objects near the vehicle, avoid
making contact by using the brakes and other maneuvers.

• Do not touch the spoke of the steering wheel while the around view monitor with Park Assist is operating. It

could cause injuries to hands or fingers. Keep neckties, scarves. etc. away from the steering wheel since
they may get entangled and cause unexpected accidents.

• Do not drive looking only at the screen. It could cause unexpected accidents or cause the vehicle to contact

surrounding objects.

• When assistance from the around view monitor with Park Assist is no longer necessary, turn off the system

by touching the “Cancel” button on the screen. If the around view monitor with Park Assist remains on, the
steering wheel may operate automatically and may cause unexpected accidents.

• Make sure that there is enough space for parking maneuvers before starting to use the around view monitor

with Park Assist.

• Keep in mind that the front of the vehicle may swing out towards oncoming traffic while the around view

monitor with Park Assist.

• Do not use the around view monitor with Park Assist under the following conditions.
- On unpaved roads.
- On slippery roads like snow-covered or frozen roads.
- On uneven roads with slants, bumps, curbstones, wheel tracks, etc.
- On curved roads.
- At mechanical parking facilities.
- Where parking or stopping is prohibited.
- When tire chains or a spare tire are installed.
- When the vehicle is being towed.
- When the doors (including the back door) are not closed.
- When transporting a load that protrudes from own vehicle.
- When the vehicle is laden with heavy loads.

PHENOMENA WHICH CAN BE EASILY MISTAKEN FOR MALFUNCTIONS

Perpendicular Mode

• After the white line is automatically detected and fine adjustment of the target parking rectangle is per-

formed, if the vehicle is moved before “Start” (start switch) is pressed, the target parking rectangle returns to
its initial position (position prior to fine adjustment).

• When aligning the parking rectangle position in the display, if the vehicle drives for 5 seconds or more or

drives at a speed of 4 km/h or more, then the target parking rectangle and forward/reverse starting position
rectangle disappear and the guidance message changes to “Check directly for safety around the vehicle”.

Perpendicular Parking Mode and Parallel Parking Mode

• The steering wheel does not fully return to straight-ahead (neutral position) when the around view monitor

with Park Assist is ended.

PRECAUTIONS

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

INFOID:0000000010774365

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:0000000010774366

• 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 1 or Instruction 2 described below.
For vehicles parked by ignition switch OFF, refer to Instruction 2.

INSTRUCTION 1

1.

Open the hood.
