Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951574
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 the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified 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 Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 minutes before performing any service.
Precaution for WorkINFOID:0000000009463520
• When removing or disassembling each component, be careful not to damage or deform it. If a component may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a s hop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
- Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

SYSTEM
The LOOSE FUEL CAP message will display in the information display when the fuel-filler cap is not tightened
correctly. The message will turn off as soon as the EC M detects the fuel-filler cap is properly tightened. The
ECM provides a loose fuel cap signal to the combination meter via CAN communication.
LOW TIRE PRESSURE WARNING
This warning appears when the BCM detects low inflati on pressure or a system malfunction. The BCM sends
a signal to the combination 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.
DOOR OPEN WARNING
This warning appears when the ignition switch is ON and the door is open. The BCM receives a door switch
signal from the door open door switch. The BCM sends t he door switch signal to the combination meter via
CAN communication lines.
TRUNK OPEN WARNING
This warning appears when the ignition switch is ON and the trunk is opened. The BCM receives a trunk lamp
switch signal from the trunk lamp switch. The BCM s ends the trunk lamp switch signal to the combination
meter via CAN communication.
LOW FUEL WARNING
This warning appears when the fuel level in the fuel tank is less than approximately 4 US gal (15 L, 3.3 Imp
gal). A variable resistor signal is supplied to the combi nation meter from the fuel level sensor unit to determine
the amount of fuel in the fuel tank.
LOW WINDSHIELD WASHER FLUID WARNING
When the windshield washer fluid level is low, the was her fluid level switch provides a ground signal to the
combination meter and the warning is displayed. Once fluid is added, the switch opens and the warning is no
longer displayed.
RELEASE PARKING BRAKE WARNING
When the parking brake is applied, the parking brake switch provides a ground signal to the combination
meter. When the vehicle speed is greater than 4 MPH (7 km/h), the message is displayed and the warning
chime sounds.
SHIFT POSITION INDICATOR
Displays the position of the shift selector based on signals received from TCM via CAN communication.
LOW OIL PRESSURE WARNING
The low oil pressure warning appears in the information display when the combination meter receives a low
engine oil pressure signal from the ECM via CAN communication.
WARNING CHECK INDICATION
The combination meter can cause an interrupt on the information display to indicate a warning, based on sig-
nals received from each unit and switch.
