Description

INFOID:0000000010417069

CHASSIS CONTROL

• Chassis Control will not provide all the necessary controls to replace driver intervention. It is not designed to

prevent loss of control. It is the driver’s responsibility to stay alert, drive safely, keep the vehicle in the travel-
ing lane, and be in control of vehicle at all times.

• Chassis Control is primarily intended for use on well-developed freeways or highways. It may not perform

satisfactorily in certain roads, weather or driving conditions.

• Using Chassis Control under some conditions of road, corner or severe weather could lead to an unex-

pected system operation. In such conditions, driver needs to correct the vehicle's direction with driver's
steering operation to avoid accidents.

• When Chassis Control is operating, avoid excessive or sudden steering maneuvers. Otherwise, you could

lose control of the vehicle.

• Engine Brake Control is designed to enhance braking feel and traceability at corners.
• Active Ride Control is designed to enhance handling and drive comfort.
• Active Trace Control is designed to enhance traceability at corners and smooth vehicle movement for more

confident driving.

• Chassis Control may not function properly under the following conditions:
- During bad weather (rain, fog, snow, wind, etc.).
- When driving on slippery roads, such as on ice or snow, etc.
- When driving on winding or uneven roads.
- When driving with a tire that is not within normal tire conditions (for example, tire wear, low tire pressure,

installation of spare tire, tire chains, non-standard wheels).

- When the vehicle is equipped with non-original steering parts or suspension parts.
• The functions of Chassis Control may or may not operate properly under the following conditions:
- On roads covered with water, dirt or snow, etc.
- On roads where there are sharp curves.

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

INFOID:0000000010464120

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:0000000010519323

• 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

Open the hood.

PRECAUTIONS

Turn key switch to the OFF position with the driver side door opened.

Get out of the vehicle and close the driver side door.

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.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

INSTRUCTION 2 (FOR VEHICLES PARKED BY IGNITION SWITCH OFF)

Unlock the door with intelligent key or remote keyless entry.
NOTE:
At this moment, ACC power is supplied.

Open the driver side door.

Open the hood.

Close the driver side door.

Wait at least 3 minutes.

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.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

• Around View Monitor with park assist that supports driving operation when parking is adopted.
• Around View Monitor with park assist is a function in which the system operates the steering wheel to assist

the steering operations of the driver when performing parallel parking or entering a garage.

• When the target parking position is set on the Around View Monitor, the conditions surrounding the vehicle,

the predicted course lines, and the turning guidance box, etc. are shown on the monitor, and while assisting
the drivers steering wheel operations, the system provides driving operation guidance so that the vehicle is
parked close to the set parking guidance box.

• In parallel parking mode, the parking space is detected by ultrasound waves, and the driver is notified. When

the driver performs Parking Assist start operation, the system assists steering wheel operation while guiding
driving operation, for parking maneuvers performed near the parking space.
