PRECAUTIONS

FOR USA AND CANADA

FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR 
BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000005688764

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

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 “SRS AIR BAG”.

• 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.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, DO NOT 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.

FOR USA AND CANADA : Precaution Necessary for Steering Wheel Rotation after 
Battery Disconnect

INFOID:0000000005688766

NOTE:
• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-

tion, 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-III 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.

Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)

3.

Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.

4.

Perform the necessary repair operation.

When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)

6.

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

FOR USA AND CANADA : Precaution for Procedure without Cowl Top Cover

INFOID:0000000005688768

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

FOR USA AND CANADA : Precaution for Brake System

INFOID:0000000005516191

WARNING:

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

CAUTION:

• Brake fluid use refer to 

MA-15, "FOR NORTH AMERICA : 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

crowfoot (A) and torque wrench (B).

• 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.

- Front brake pad: refer to 

BR-16, "BRAKE PAD : Inspection and Adjustment"

.

- Front disc rotor: refer to 

BR-16, "DISC ROTOR : Inspection and Adjustment"
