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 SRC 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 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 the SRC 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 har-
ness connectors.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000001095720

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 power is interrupted, follow the procedure below before
starting the repair operation.

OPERATION PROCEDURE

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

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.

Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.

Perform the necessary repair operation.

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.)

Perform a self-diagnosis check of all control units using CONSULT-III.

Precaution for Brake System

WARNING:

Clean any dust from the front brake and rear brake with a vacuum dust collector. Never blow with com-
pressed air.

PRECAUTIONS

CAUTION:

• Only use “DOT 4” brake fluid. Refer to

MA-21, "Fluids and Lubricants"

• Never reuse drained brake fluid.
• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it

off immediately and wash with water if it gets on a painted surface.

• Always clean with new brake fluid when cleaning the master cylinder, brake caliper and other com-

ponents.

• Never use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and

cause improper operation.

• Always loosen the brake tube flare nut with a flare nut wrench.
• Tighten the brake tube flare nut to the specified torque with

flare nut torque wrench (A).

• Always confirm the specified tightening torque when install-

ing the brake pipes.

• Turn the ignition switch OFF and disconnect the ABS actuator

and electric unit (control unit) connector or the battery nega-
tive terminal before performing the work.

• Check that no brake fluid leakage is present after replacing

the parts.

• Burnish the brake contact surfaces after refinishing or replac-

ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage. Refer to

BR-36, "BRAKE PAD : Inspection

and Adjustment"

(front brake pad),

BR-40, "BRAKE CALIPER ASSEMBLY : Inspection and Adjust-

ment"

(front disc rotor),

BR-41, "BRAKE PAD : Inspection and Adjustment"

(rear brake pad),

BR-45,

"BRAKE CALIPER ASSEMBLY : Inspection and Adjustment"

(rear disc rotor).
