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

INFOID:0000000010715440

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. 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 Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000010715441

the lower end of windshield with urethane, etc to prevent damage to
windshield.

Precaution for Handling High Pressure Fuel System

INFOID:0000000010715443

• High pressure fuel system components are between high pressure fuel pump and fuel injector.
• Always release fuel pressure and never start the engine when performing removal and installation.
• When removing or installing parts without releasing fuel pressure, fuel may be splashed and, if fuel contacts

skin or eyes, it may cause inflammation.

Special Cautions to Ensure the Safe Disposal of Sodium-filled Valves

INFOID:0000000010715444

Handling and disposal of sodium-filled valves requires special care
and consideration. Under conditions such as breakage with subse-
quent contact with water, metal sodium which lines the inner portion
of valve will react violently, forming sodium hydroxide and hydrogen
which may result in an explosion. Sodium-filled valve is identified on
the top of its stem as shown in illustration.

DEALER DISPOSAL INSTRUCTIONS

CAUTION:

• Use approved shatter-resistant eye protection when performing this procedure.
• Perform this and all subsequent disposal work procedures in an open room, away from flammable

liquids. Keep a fire extinguisher, rated at least 10 ABC, in close proximity to the work area.

• Be sure to wear rubber gloves when performing the following operations.
• Make sure the resultant (high alkalinity) waste water does not contact your skin. If the waste water

does contact you, wash the contacted area immediately with large quantities of water.

• Dealers should check their respective state and local regulations concerning any chemical treatment

or waste water discharge permits which may be required to dispose of the resultant (high alkalinity)
waste water.

< PRECAUTION >

[MR20DD]

Clamp valve stem in a vice.

The valve has a specially-hardened surface. To cut through it,
first remove a half-round section, approximately 30 mm (1.18 in)
long using air-powered grinder until black color is removed and
silver color appears.

Use hacksaw to cut through approximately half the diameter of
valve stem. Make the serration at a point 40 mm (1.57 in) from
the end of valve stem.

Cover the serrated end of the valve with a large shop towel (A).
Strike the valve face end with a hammer, separating it into two
pieces.

Fill a bucket (such as a 20 oil can) with at least 10 (2-1/4
lmp gal) of water. Carefully place the already cut (serrated)
valves into the water one-at-a-time using a set of large tweezers
and quickly move away at least 2.7 m (9 ft).

The valves should be placed in a standing position as shown in
the illustration to allow complete reaction. After the bubbling
action has subsided, additional valves can be placed into the
bucket allowing each subsequent chemical reaction to subside.
However, no more than 8 valves should be placed in the same
10 (2-1/4 lmp gal) amount of water. The complete chemical
reaction may take as long as 4 to 5 hours. Remove the valves
using a set of large tweezers after the chemical reaction has
stopped. Afterwards, valves can be disposed as ordinary scrap.
