PRECAUTIONS

Precaution for Working Range at a Regular Dealership

INFOID:0000000009167065

CAUTION:

The service items unmentioned on this manual are recommended to be performed by a GT-R certified
NISSAN dealer. Because those service items require special equipment and a GT-R certified technical
staff who completed special training.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000009159829

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:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

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

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never 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.

Precautions Necessary for Steering Wheel Rotation After Battery Disconnection

INFOID:0000000009159830

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition switch to the LOCK position,

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 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

Connect both battery cables.

Revision: 2012 November

2014 GT-R

BR-4

< PRECAUTION >

PRECAUTIONS

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

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

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

Perform the necessary repair operation.

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

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

Precaution for Battery Service

INFOID:0000000009159831

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000009159832

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

General Precautions

INFOID:0000000009159833

CAUTION:

After finishing servicing, check that all the tools and waste are stored in a customary place.

Precaution for Brake System

INFOID:0000000009159834

WARNING:

Since dust covering the front and rear brakes has an affect on human body, the dust must be removed
with a dust collector. Never splatter the dust with an air blow gun.
• Brake fluid use refer to

MA-22, "Fluids and Lubricants"

• Never reuse drained brake fluid.
• The brake fluid used for this vehicle has a higher boiling point and readily absorbs moisture in the air.

Accordingly, when brake temperature rises, water in brake fluid vaporizes with the higher potential of vapor
lock and uncomfortable brake pedal feeling (increase in pedal stroke). Therefore, the following items must
be carefully observed.

- Never change, bleed, or fill with brake fluid under humid conditions such as rainy or foggy days, in principle,

because the brake fluid absorbs moisture in the air. (Vapor lock occurs more easily during performance driv-
ing because brake temperature becomes higher, compared with normal driving.)

- If it is necessary to change, bleed, or fill with brake fluid under humid conditions such as rainy or foggy days,

perform this in a place with low humidity in minimal time.

- When it is necessary to change, bleed, or fill with brake fluid, explain the customer the precautions on brake

fluid before deciding the place and schedule of the work.

- Always discard residual brake fluid remaining in the container because the fluid is deteriorated by moisture.
• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it out

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

• Never scratch the flare nut and the brake caliper.

PRECAUTIONS

BR-5

< PRECAUTION >

• After pressing the brake pedal more deeply or harder than normal driving, such as when air bleeding, check

each item of brake pedal. Adjust brake pedal if it is outside the standard condition.

• Always clean with new brake fluid when cleaning the master cylinder, brake caliper and other components.
• Never use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and cause a

malfunction.

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

foot (A) and torque wrench (B).

• Always confirm the specified tightening torque when installing the

brake pipes.

• Turn the ignition switch OFF and disconnect the ABS actuator and

electric unit (control unit) connector or the battery negative terminal
