PRECAUTION

PRECAUTIONS

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

INFOID:0000000008462886

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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
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.

Precaution for Battery Service

INFOID:0000000008462887

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Service Procedure Precautions for Models with a Pop-up Roll Bar

INFOID:0000000008462888

WARNING:

Always observe the following items for preventing accidental activation.
• Risk of passenger injury or death may increase if the pop-up roll bar does not deploy during a roll

over collision. In order to reduce the chance of an incident where the pop-up roll bar is inoperative,
all maintenance must be performed by a NISSAN or INFINITI dealer.

• Before removing and installing the pop-up roll bar component parts and harness, always turn the

ignition switch OFF, disconnect the battery negative terminal, and wait for 3 minutes or more. (The
purpose of this operation is to discharge electricity that is accumulated in the auxiliary power supply
circuit in the air bag diagnosis sensor unit.)

• When repairing, removing, and installing a pop-up roll bar, always refer to SRS AIR BAG and SRS

AIR BAG CONTROL warnings in the Service Manual.

OPERATION DESCRIPTION

• Turn rear window defogger switch ON while ignition switch is ON. Then multifunction switch (rear window

defogger switch) transmits rear window defogger switch signal to AV control unit via AV communication. AV
control unit transmits rear window defogger switch signal to BCM via CAN communication.

• BCM turns rear window defogger relay ON and transmits rear window defogger control signal to IPDM E/R

via CAN communication when rear window defogger switch signal is received.

• Door mirror defoggers are supplied with power and operate when rear window defogger relay turns ON.
• Rear window defogger relay sends power supply to soft top control unit.
• Soft top control unit detects roof state and controls rear window defogger operation.
• IPDM E/R transmits rear window defogger control signal to AV control unit via CAN communication.
• When receiving the signal, AV control unit indicates rear defogger ON on the display. At the same time, AV

control unit transmits rear window defogger feedback signal to multifunction switch (rear window defogger
switch) via AV communication and illuminates rear window defogger switch indicator.

TIMER FUNCTION

• BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch

is turned ON. It makes rear window defogger and door mirror defoggers operate.

• Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns

rear window defogger relay OFF. The same operation also occurs during timer operation, if the ignition
switch is turned OFF.
