PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010783657
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:0000000010783658
CAUTION:
Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition power source and accessory
power source to the OFF, then disconnect both battery cables.
• After finishing work, confirm that all control unit connectors are connected properly, then re-connect
both battery cables.
• Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing
work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.
OPERATION PROCEDURE
1.
Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2.
Open driver door.
3.
Turn the ignition switch to the ON position.
(At this time, the steering lock will be released.)
4.
Turn the ignition switch to OFF position with driver door open.
5.
Wait for 3 minutes or longer with driver door open.
NOTE:
• Do not close driver door because the steering wheel locks when driver door is closed.

• The auto acc function is adapted to this vehicle. For this reason, even when the ignition switch is turned
to OFF position, the accessory power source does not turned OFF and continues to be supplied for a
certain amount of time.
6.
Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
7.
Perform the necessary repair operation.
8.
When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the ignition switch from OFF position to ON position, then to LOCK position. (The steering wheel will lock
when the ignition switch is turned to LOCK position.)
9.
Perform self-diagnosis check of all control units using CONSULT.
Precaution for Procedure without Cowl Top Cover
INFOID:0000000010783659
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.
Precaution for Handling High Pressure Fuel System
INFOID:0000000010783660
• 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:0000000010783661
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.

PRECAUTIONS
1.
Clamp valve stem in a vice.
2.
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.
3.
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.
4.
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.
5.
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).
6.
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.
Precautions For Engine Service
INFOID:0000000010783662
DISCONNECTING FUEL PIPING
• Before starting work, check no fire or spark producing items are in the work area.
• Release fuel pressure before disconnecting and disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
DRAINING ENGINE COOLANT
Drain engine coolant and engine oil when the engine is cooled.
