PRECAUTIONS

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

INFOID:0000000008462606

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:0000000008462607

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:0000000008462608

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.

Service Notice and Precautions for TPMS

INFOID:0000000008462609

• Low tire pressure warning lamp blinks for 1min, then turns ON when occurring any malfunction except low

tire pressure. Delete the memory with CONSULT, or register the ID to turn low tire pressure warning lamp

PRECAUTIONS

OFF. Refer to 

WT-10, "AIR PRESSURE MONITOR : CONSULT Function (BCM - AIR PRESSURE MONI-

TOR)"

, 

WT-19, "Work Procedure"

.

• ID registration is required when replacing or rotating wheels, replacing tire pressure sensor or BCM. Refer to

WT-19, "Work Procedure"

• Replace grommet seal, valve core and cap of tire pressure sensor in TPMS every tire replacement by reach-

ing wear limit of tire. Refer to 

WT-46, "Exploded View"

.

Service Notice and Precautions for Road Wheel

INFOID:0000000008462610

• Genuine NISSAN aluminum wheel is designed for each type of vehicle. Use it on the specified vehicle only.
• Use Genuine NISSAN parts for the road wheels, valve caps and wheel nuts.
• Always use them after adjusting the wheel balance. For the balance weights, use Genuine NISSAN alumi-

num wheel weights.

• Use caution when handling the aluminum wheels, because they can be easily scratched. When removing

dirt, do not use any abrasives, a wire brush, or other items that may scratch the coating. Use a neutral deter-
gent if a detergent is needed.

• After driving on roads scattered with anti-icing salts, wash off the wheels completely.
• When installing road wheels onto the vehicle, always wipe off any dirt or foreign substances to prevent them

from being trapped between the contact surfaces of wheel.

• Never apply oil to nut and bolt threads.
• When tightening the valve cap there is a risk of damaging the valve cap if a tool is used. Tighten by hand.

SELF DIAGNOSTIC RESULT

Refer to 

BCS-55, "DTC Index"

.

When “CRNT” is displayed on self-diagnosis result,

• The system is presently malfunctioning.

When “PAST” is displayed on self-diagnosis result,

• System malfunction in the past is detected, but the system is presently normal.

DATA MONITOR MODE

Screen of data monitor mode is displayed.
NOTE:
• When malfunction is detected, CONSULT perform REAL-TIME DIAGNOSIS.

Also, any malfunction detected while in this mode will be displayed at real time.

• The following table includes information(items)inapplicable to this vehicle. For information(items)applicable

to this vehicle, refer to CONSULT display items.

NOTE:
Before performing the self-diagnosis, be sure to register the ID, or erase the actual malfunction location may
be different from that displayed on CONSULT.

ACTIVE TEST MODE

NOTE:
Before performing the self-diagnosis, be sure to register the ID, or erase the actual malfunction may be differ-
ent from that displayed on CONSULT.
