Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951708
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 three mi nutes before performing any service.
Service Notice and Precautions for TPMSINFOID:0000000009464472
WARNING:
Radio waves could adversely affect electrical medi cal equipment. Those who use a pacemaker should
contact the electrical medical equipment manu facturer for possible influences before use.
• Low tire pressure warning lamp blinks for 1 minute, then turns ON when any malfunction occurs except low
tire pressure. Erase the self-diagnosis memories for Tire Pressure Monitoring System (TPMS), or register
the ID to turn low tire pressure warning lamp OFF. For ID registration, refer to WT-25, "Work Procedure"
.
• ID registration is required when replacing or rotating wheels, replacing tire pressure sensor or BCM. Refer to WT-25, "Work Procedure"
.
• For easy fill tire alert function, refer to the following. WT-9, "Easy Fill Tire Alert Function"
- When inflating the tires, park the vehicle in the safe area and ensure the safety of the working area.
- Read and understand the easy fill tire alert function prior to use.
- Inflate the tires one at a time.
- If there is no response for approximately 15 seconds or mo re after inflating the tires, cancel the use of the
easy fill tire alert function or move the vehicle approximately 1 m (3.2 ft) backward or forward to try again.
The air filler pressure may be weak or out of service area.
- Despite the high-precision TPMS pressure sensor, an i ndicated value may differ from that of the pressure
gauge.
- Air pressure is measured rather high due to the rise in tire air temperature after driving.
- If TPMS is malfunctioning, the easy fill tire alert is unusable.
• Replace grommet seal, valve core and valve cap of tire pressure sensor in TPMS when replacing each tire
by reaching the wear limit. Refer to WT-57, "Exploded View"
.
• Because the tire pressure sensor conforms to No rth America radio law, the following items must be
observed.
- The sensor may be used only in North America.
- It may not be used in any method other than the specified method.
- It must not be disassembled or modified.

TransmitterINFOID:0000000009464479
A sensor-transmitter integrated with a valve is instal led in each wheel, and transmits a detected air pressure
signal in the form of a radio wave. The radio signal is received by the remote keyless entry receiver.
Remote Keyless Entry ReceiverINFOID:0000000009464480
The remote keyless entry receiver receives the air pressure signal transmitted by the transmitter in each
wheel.
Outside Key AntennasINFOID:0000000009464481
For vehicles equipped with individual tire pressure display in the combination meter, the outside key antennas
(driver side, passenger side and rear bumper) are used by the BCM to identify the location of the transmitters.
Combination MeterINFOID:0000000009464482
The combination meter receives tire pressure status from the BCM via CAN communication. The combination
meter will display the low tire pressure warning lamp when a low tire pressure or system malfunction is
detected by the BCM. A warning message will also be displayed in the vehicle information display. Refer to the
Owner’s Manual for additional information.

System DescriptionINFOID:0000000009464484
When the vehicle has reached a speed of 40 km/h (25 MPH) or greater, the BCM receives a signal transmitted
from the tire pressure sensors/transmitters installed in each wheel. If the BCM detects low inflation pressure or
a system malfunction, it sends a signal to the combi nation meter via CAN communication to illuminate the low
tire pressure warning lamp. In addition, a warning message will be displayed in the vehicle information display.
Refer to the Owner’s Manual for additional information.
The tire pressure monitoring system (TPMS) has Easy fill ti re alert function to aid in tire inflation. Refer to WT-
9, "Easy Fill Tire Alert Function".
Low Tire Pressure Warning Lamp and Display Indications
Easy Fill Tire Alert FunctionINFOID:0000000009464485
NOTE:
When beginning tire inflation, it takes a few seconds for t he Easy fill tire alert to function. If there is no
response for approximately 15 seconds or more, cancel t he Easy fill tire alert function and move the vehicle
approximately 1 m (3.2 ft) backward or forward to try again.
• The Easy fill tire alert function operates only when t he select lever position is in P-range with the ignition
switch ON.
• This function informs the driver with a visual and audible indication that the recommended COLD tire pres-
sure has been reached.
• The hazard warning lamps blink when the recommended COLD tire pressure has been reached. After the recommended COLD tire
pressure has been reached, the horn sounds once and the hazard
warning lamps stop blinking.
• If the tire pressure value is equal to or greater than 30 kPa (0.31
kg/cm
2, 4 psi) more than the recommended COLD tire pressure,
the hazard warning lamps flash and horn sounds three times.
• To return the tire to the recommended COLD tire pressure, deflate
the tire until the horn sounds once and the hazard warning lamps
stop blinking.
