Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006417198
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. 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 w hether 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:
• To avoid rendering the SRS inopera tive, 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 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 “SRS AIR BAG”.
Do not use electrical test equipmen t 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 Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT 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 minu tes before performing any service.

PERIODIC MAINTENANCE
ENGINE COOLANT
InspectionINFOID:0000000006289657
LEVEL
Check if the reservoir tank engine coolant level is within the “MIN”to “MAX” when the engine is cool.
Adjust the engine coolant level if necessary. WARNING:
Never remove reservoir tank cap when engine is hot.
LEAKAGE
To check for leakage, apply pressure to the cooling system with theradiator cap tester and radiator cap tester adapter (commercial
service tool) (A).
WARNING:
Never remove radiator cap and reservoir tank cap when
engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from water inlet.
CAUTION:
Higher test pressure than specified may cause radiator dam-
age.
NOTE:
In a case that engine coolant decreas es, fill radiator with engine coolant.
If anything is found, repair or replace damaged parts.
DrainingINFOID:0000000006289658
WARNING:
Never remove radiator cap and reservoir tank cap when engine is hot. Serious burns could occur
from high-pressure engine co olant escaping from radiator.
Wrap a thick cloth around the caps. Slowly turn them a quarter of a turn to release built-up pressure.
Carefully remove the caps by turning it all the way.
1. Open radiator drain plug (1) at the bottom of radiator, and then remove radiator cap and reservoir tank cap.
When draining all of engine cool ant in the system, open water drai n plug on cylinder block. Refer
to EM-103, "
Setting".
2. Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.
