DESCRIPTION
NOTE:
If customer reports a “No start” condition, request ALL KEYS to be brought to a Nissan dealer in case
of a NATS malfunction.
NATS (Nissan Anti-Theft System) has the following functions:
• NATS shows a higher anti-theft performance at preventing engine to be started by an unregistered key. (reg- istered key: mechanical key and Intelligent Key).
• Only a key with key ID registered in BCM and ECM c an start engine, it has a higher protection against auto
theft that duplicates keys.
• If a malfunction has been detected, security indicator will illuminate when ignition switch is in ON position.
• If the owner requires, mechanical key can be registered for up to 5 keys.
• During trouble diagnosis or when the following parts have been replaced, and if mechanical key is added,
registration* is required.
*: All mechanical keys of the vehicle should be registered.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005396972
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:0000000005396973
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.

5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Brake SystemINFOID:0000000005396974
• Refill using recommended brake fluid. Refer to MA-14.
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted surface of body. If brake fluid is splashed on painted surfaces of body immediately wipe it off with cloth and then wash it away with water.
• To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
• Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
• Use a flare nut wrench when removing a brake tube and use a flare nut torque wrench when installing a brake tube.
• When installing brake tubes and hoses, be sure to check torque.
• Before working, turn igniti on switch OFF and disconnect connec-
tors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
• Burnish the new braking surfaces after refinishing or replacing drums or rotors, after replacing p ads or linings, or if a soft pedal
occurs at very low mileage. Refer to BR-34, "
Brake Burnishing
Procedure" .

BRAKE TUBE AND HOSE
• All tubes and hoses must be free from excessive bending, twisting and pulling.
• Make sure there is no interference with other part s when turning steering both clockwise and coun-
terclockwise.
• Brake tubes and hoses are an important safety part. Always disassemble the parts and retighten
their fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part
is detected.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted surfaces of body , immediately wipe them with cloth and then wash it away with
water.
• Do not bend or twist brake hose sharply, or strongly pull it.
• When removing components, cover brake line connect ions so that dirt, dust, or other foreign mat-
ters do not get in.
