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:0000000009160407

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.

Inspection

INFOID:0000000009160410

BASIC INSPECTION

Checking Engine Room

• Visually check engine room for smears*

and leakage*

of engine coolant when engine is cool.

NOTE:
• *

: Engine coolant does not drop.

• *

: Engine coolant drop.

- Check engine assembly and cooling system for smears and leakage of engine coolant.
- Observe the clearance between the engine and radiator to check that there is no engine coolant collected on

the front under cover.

Additional Inspection

• Check that engine coolant temperature history is not stored in ECM. (This work is recommended to be per-

formed by GT-R certified NISSAN dealer.)

• Perform this additional inspection after driving under conditions listed below:
- Higher-RPM (approaching redline) operation
- Frequent high pedal force braking from moderate and higher speeds
- Frequent throttle activation
- Fast revving throughout the RPM range

Remove front under cover. Refer to

EXT-37, "FRONT UNDER COVER : Exploded View"

Visually check the bottom of the engine for smears and leakage of engine coolant.

LEVEL

• Check that the reservoir tank engine coolant level is at the mid-

point between the “MIN” (B) to “MAX” (A) with the engine cold.

CAUTION:

• If engine coolant level exceeds the MAX line, leakage of

engine coolant may occur during the rise in internal pres-
sure in the engine coolant path. Therefore, thoroughly
check that engine coolant level is below the MAX line.

• Refill Genuine NISSAN Long Life Antifreeze/Coolant (blue)

or equivalent in its quality mixed with water (distilled or
demineralized). Refer to

MA-22, "Fluids and Lubricants"

• Adjust the engine coolant level if necessary.
• Check that the reservoir tank cap is tightened.

LEAKAGE

Engine Assembly

Visually check engine assembly and surround area for smears of engine coolant.

Wipe out smeared engine coolant using part cleaner or the equivalent.

Check again for engine coolant smears.
