In the vehicle without Intelligent Key system, security indicator always flashes with other than ignition
switch ON or START position.
In the vehicle with Intelligent Key system, security indicator always flashes with mechanical key removed
condition (key switch OFF) and ignition knob released condition on LOCK position (ignition knob switch
OFF).
Therefore, IVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.
If system detects malfunction, it turns on security indicator in ignition switch ON position.
If the owner requires, mechanical key ID can be registered for up to 5 keys.
During trouble diagnosis or when the following parts have been replaced, and if ignition key or mechanical
key is added, registration* is required.
*: All keys kept by the owner of the vehicle should be registered with ignition key or mechanical key.
–ECM
–BCM
–Ignition key (models without Intelligent Key system)
–Mechanical key (models with Intelligent Key system)
IVIS (NATS) trouble diagnoses, system initialization and additional registration of other IVIS (NATS) igni-
tion key or mechanical key IDs must be carried out using CONSULT-II hardware and CONSULT-II IVIS
(NATS) software. When IVIS (NATS) initialization has been completed, the ID of the inserted ignition key
or mechanical key or mechanical key IDs can be carried out.
Regarding the procedures of IVIS (NATS) initialization and ignition key or mechanical key ID registration,
refer to CONSULT-II operation manual, NATS-IVIS/NVIS.
SECURITY INDICATOR
Warns that the vehicle has IVIS (NATS).
In the vehicle without Intelligent Key system, security indicator always flashes with other than ignition
switch ON or START position. In the vehicle with Intelligent Key system, security indicator always flashes
with mechanical key removed condition (key switch OFF) and ignition knob released condition on LOCK
position (ignition knob switch OFF).
NOTE:
Because security indicator is highly efficient, the battery is barely affected.
Condition of Security Indicator
WITHOUT INTELLIGENT KEY SYSTEM
WITH INTELLIGENT KEY SYSTEM
In ignition knob operation with Intelligent Key, it always turns on with pushing ignition knob, and always
flashes with ignition knob released (ignition knob switch OFF) condition on ignition knob “LOCK” position.
In ignition knob operation with mechanical key, it turns off on the condition that mechanical key is inserted
in key cylinder, and always flashes with ignition knob released (ignition knob switch OFF) condition on
mechanical key removed condition.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AFS0028A
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. 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 whether 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 inoperative, 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 per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Brake SystemAFS001MQ
Recommended fluid is brake fluid “DOT 3”.
Do not reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas.
To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.
Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
Use flare nut wrench when removing and installing brake tube.
When installing brake piping, be sure to check torque.
Before working, turn ignition switch OFF and disconnect con-
nectors for ABS actuator and electric unit (control unit) or battery
terminal.
Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to BR-24, "
BRAKE BURNISHING PROCEDURE" .
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe
with a dust collector.SBR686C

On-board InspectionAFS001MV
LEVEL CHECK
Make sure the fluid level in reservoir tank is within the standard
(between MAX and MIN lines).
Visually check around reservoir tank for fluid leaks.
If fluid level is excessively low, check brake system for leaks.
If brake warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Drain and RefillAFS001MW
CAUTION:
Refill with new brake fluid “DOT3”.
Do not reuse drained brake fluid.
Do not let brake fluid splash on the painted surfaces of the body. This might damage the paint, so
when splashing it, immediately wipe off the area and wash away with water.
Before servicing, disconnect actuator connector or battery negative cable.
1. Connect a vinyl tube to each bleed valve.
2. Depress brake pedal, loosen each bleed valve, and gradually
remove brake fluid.
3. Make sure there is no foreign material in reservoir tank, and refill
with new brake fluid.
4. Rest foot on brake pedal. Loosen bleed valve. Slowly depress
pedal until it stops. Tighten bleed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.
Bleed Air. Refer to BR-10, "
Bleeding Brake System" .

Bleeding Brake SystemAFS001MX
CAUTION:
While bleeding, pay attention to master cylinder fluid level.
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector or battery
negative terminal.
2. Connect a vinyl tube to the rear right bleed valve.
3. Fully depress brake pedal 4 to 5 times.
4. With brake pedal depressed, loosen bleed valve to let the air out, and then tighten it immediately.
5. Repeat steps 3, 4 until no more air comes out.
6. Tighten bleed valve to the specified torque. Refer to BR-20, "
Components" (front disc brake), BR-25,
"Components" (rear disc brake).
7. In steps 2 to 6 below, with master cylinder reservoir tank filled at least half way, bleed air from the front left,
rear left, and front right bleed valve, in that order.
