Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005713806
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 severity 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 and SB section of this Service Man-
ual.
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 NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect 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 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 3 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005399808
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK ″ position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
4. Perform the necessary repair operation.

just after the engine is turned off.
• Be careful not to cut your ha nd on heat insulator edges.
CAUTION:
• Use genuine NISSAN exhaust system parts or equivalent, which are specially designed for heat resistance, corrosion resistance and shape.

INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Always replace exhaust gaskets and seal bearings with new ones
when installing.
• Before installing a new heated oxygen sensor, clean and apply an ti-seize lubricant to exhaust sys-
tem threads using suitable tool.
• Discard any heated oxygen sensor which has been dr opped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a co ncrete floor; install a new one.
• Do not over-tighten the heated oxygen sensor. Doing so may damage the heated oxygen sensor,
resulting in the MIL coming on.
• Remove deposits from the sealing surface of each connection. Connect them securely to avoid
exhaust leakage.
• Temporarily tighten nuts on the exhaust manifold side and bolts on the vehicle side. Check each part
for unusual interference, and then tighten them to the specified torque.
• When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
NOTE:
If ground cable was removed, it is not necessary to reinstall it.
Exhaust Manifold to Exhaust Front Tube
1. Securely insert seal bearing (2) into exhaust manifold (1) side in the direction shown.
• Exhaust front tube (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. Install spring (3), tighten nut (4). • Be careful that the stud bolt nut does not interfere with the
flanged area ( ).
• Make sure the spring (3) sits properly on the flange surface by aligning it to the locator dimples.
Exhaust Front Tube to Center Muffler
1. Securely insert seal bearing (2) into exhaust front tube (1) side
in the direction shown.
• Center muffler (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. Install spring (3), tighten bolt (4). • Be careful that the stud bolt does not interfere with the flanged
area ( ).
• Make sure the spring (3) sits properly on the flange surface by aligning it to the locator dimples.
INSPECTION AFTER INSTALLATION
• With the engine running, check exhaust tube joints for exhaust leakage and unusual noise.
• Check to ensure that brackets and mounting rubbers are installed properly and free from undue stress. Improper installation could result in excessive noise and vibration. Oxygen sensor thread cleaner : — (J-43897-18)
