TRANSMISSION SETTINGS
The design o�b the clutch and transmission
requires inspection and adjustment o�b the clutch
and shi�bt �borks by a �fT-R certi�bied NISSAN
dealer at the recommended intervals. I�b the
transmission setting is not complete, excessive
loads may be applied to the transmission and
power train system parts during starting and
shi�bting, which may result in a mal�bunction or
damage. Depending on the driving conditions,
more �brequent adjustments may be necessary to
help maximize vehicle per�bormance.NOTICE
Follow these recommendations to ob-
tain maximum engine performance and
ensure the future reliability and econo-
my of your new vehicle. Failure to
follow these recommendations may
result in shortened engine life and
reduced vehicle performance.
Please observe the �bollowing types o�b driving
until the mileage shown below has been
reached.
Until 300 miles (500 km):
. Do not depress the accelerator pedal more
than hal�bway and avoid rapid acceleration.
. Drive with the engine speed kept at less
than 3,500 RPM.
. Avoid unnecessary quick steering, abrupt
braking and driving on poor roads.
300 to 600 miles (500 to 1,000 km):
. Avoid rapid acceleration in a low gear (1st to
3rd gears) with the accelerator pedal �bully
depressed. Depress the pedal slowly.
. Avoid unnecessary quick steering and
abrupt braking.

BREAK-IN SCHEDULE

GTR-24GT-R Overview
1588F (708C) , dri�fe the �fehi�ble until it rea�bhes
normal operating temperature. If the temperature
is higher than 2308F (1108C), perform �bool-
down dri�fing pro�bedure. (
“Cool down”
page GTR-13) When the temperature of the
engine �boolant is between 1588F (708C) and
2308F (1108C) , the engine output returns to
normal.
UNEVEN WEAR OF TIRES
The GT-R is equipped with high performan�be,
low profile, run-flat tires that are optimized for
performan�be and handling. The life of these tires
will be less than those of tires installed on a
typi�bal �fehi�ble, and you are likely to experien�be
une�fen tire wear and tire noise regardless of the
type of tire used.
NOISES ARE HEARD WHILE DRIV-
ING
. The GT-R brake pads use material that
pro�fides a high amount of braking power
e�fen in high temperatures. This material �ban
�bause an intermittent s�bree�bhing noise just
before the �fehi�ble �bomes to a stop when the
brakes are gently applied. The noise de-
�breases as the brake pads wear. Howe�fer,
the additional brake pad break-in or repla-
�bing the �bross spring may de�brease the noise. Conta�bt a GT-R �bertified NISSAN
dealer.
. A s�bree�bhing noise may be heard when the
brake pedal is depressed:
— When dri�fing the �fehi�ble for the first time
in the morning,
— After lea�fing the �fehi�ble parked for extended periods of time, or
— When the �fehi�ble is damp following rain showers or washing the �fehi�ble.
These sounds are normal. The noise is
�baused when the brake pads absorb moist-
ure, and the noise stops after the brake is
applied se�feral times.
. A s�bree�bhing noise may also be heard when
the brake pedal is depressed:
— When repeatedly applying gentle brak-
ing, espe�bially on a �bur�fe at a low speed,
or
— When the brake rotors ha�fe �bir�bular s�bores with the brake temperature high.
WARNING
Follow the instructions below when
parking the vehicle to help prevent the
brake rotor and brake pads from rust-
ing together. Failure to follow the instructions could cause the rotor and
pads to rust together. If the rotor and
pads rust together, there may be a
popping noise and some vibration
when the vehicle is driven, a wheel
may not roll correctly, or the brake pads
could be damaged. If the pads are
damaged, this may reduce the effec-
tiveness of the brake system which
could cause a collision, serious perso-
nal injury or death.
. The GT-R uses brake pad materials that
ha�fe high metalli�b �bontent. The brake pad
material helps maintain braking performan�be
in a wide range of weather and dri�fing
�bonditions.
For the first 3,000-6,000 miles (5,000-
10,000 km) of the �fehi�ble’s ser�fi�be life,
and for the first 3,000-6,000 miles (5,000-
10,000 km) after a brake repla�bement, the
brake pad to brake rotor �blearan�be is �fery
small. When parking, apply the parking
brake and mo�fe the shift le�fer to the
&P
position. Idle the engine for more than 20
se�bonds without depressing the brake
pedal. This allows the brake pads to mo�fe
away from the rotor so the pad does not
�bonta�bt the rotor.

collision or a sudden stop.
SEAT BELT MAINTENANCE
.To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or carpets�f
Then, wipe with a cloth and allow the seat
�belts to dry in the shade�f Do not allow the
seat �belts to retract until they are completely
dry�f
. If dirt builds up in the shoulder belt
guide of the seat �belt anchors, the seat
�belts may retract slowly�f Wipe the shoulder
�belt guide with a clean, dry cloth�f
. Periodically check to see that the seat
belt and the metal components such as
�buckles, tongues, retractors, flexi�ble wires
and anchors work properly�f If loose parts,
deterioration, cuts or other damage on the
we�b�bing is found, the entire seat �belt
assem�bly should �be replaced�f
WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the
seat belt becomes wrapped around a
child’s neck with the ALR mode acti-
vated, the child can be seriously injured
or killed if the seat belt retracts and
becomes tight. This can occur even if
the vehicle is parked. Unbuckle the seat
belt to release the child. If the seat belt
can not be unbuckled or is already
unbuckled, release the child by cutting
the seat belt with a suitable tool (such
as a knife or scissors) to release the
seat belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is availa�ble from
many other sources, including doctors, teachers,
government traffic safety offices, and community
organizations�f Every child is different, so �be sure
to learn the �best way to transport your child�f
There are three �basic types of child restraint systems:
.
Rear-facing child restraint
. Forward-facing child restraint
. Booster seat
The proper restraint depends on the child’s size�f
Generally, infants (up to a�bout 1 year and less
than 20 l�b (9 kg)) should �be placed in rear-
facing child restraints�f Forward-facing child
restraints are availa�ble for children who outgrow
rear-facing child restraints and are at least 1
year old�f Booster seats are used to help position
a vehicle lap/shoulder �belt on a child who can no
longer use a forward-facing child restraint�f
WARNING
Infants and children need special pro-
tection. The vehicle’s seat belts may not
fit them properly. The shoulder belt may
come too close to the face or neck. The
lap belt may not fit over their small hip
bones. In an accident, an improperly
fitting seat belt could cause serious or
fatal injury. Always use appropriate
child restraints.
All U�fS�f states and Canadian provinces or
territories require the use of approved child

CHILD SAFETY

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance
from the vehicle in front of you.
Ultimately, the driver is responsible
for safety.
. Tire type and condition may also
affect braking effectiveness. When
replacing tires, install the specified
size of tires on all four wheels. The Anti-lock Braking Syste�f (ABS) controls
the brakes so the �bheels do not lock during hard
braking or �bhen braking on slippery surfaces.
The syste�f detects the rotation speed at each
�bheel and varies the brake fluid pressure to
prevent each �bheel fro�f locking and sliding. By
preventing each �bheel fro�f locking, the syste�f
helps the driver �faintain steering control and
helps to �fini�fize s�berving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it do�bn.
Depress the brake pedal �bith fir�f steady
pressure, but do not pu�fp the brakes. The
ABS �bill operate to prevent the �bheels fro�f
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
pu�fps, hydraulic solenoids and a co�fputer. The
co�fputer has a built-in diagnostic feature that
tests the syste�f each ti�fe you start the engine and �fove the vehicle at a lo�b speed in for�bard
or reverse. When the self-test occurs, you �fay
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This does not indicate that there is
a �falfunction. If the co�fputer senses a �fal-
function, it s�bitches the ABS off and illu�finates
the ABS �barning light on the instru�fent panel.
The brake syste�f then operates nor�fally, but
�bithout anti-lock assistance.
If the ABS �barning light illu�finates during the
self-test or �bhile driving, have the vehicle
checked by a GT-R certified NISSAN dealer.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 k�f/h) . The speed varies according to
road conditions.
When the ABS senses that one or �fore �bheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is si�filar to pu�fping the brakes very
quickly. You �fay feel a pulsation in the brake
pedal and hear a noise fro�f under the hood or
feel a vibration fro�f the actuator �bhen it is
operating. This is nor�fal and indicates that the
ABS is operating properly. Ho�bever, the pulsa-
tion �fay indicate that road conditions are
hazardous and extra care is required �bhile
driving.

corners, the VDC system may not
operate properly and the VDC warn-
ing light
may illuminate. Do not
drive on these types of roads.
. When driving on an unstable sur-
face such as a turntable, ferry, elevator or ramp, the VDC warning
light
may illuminate. This is not
a malfunction. Restart the engine
after driving onto a stable surface.
. If wheels or tires other than the
those recommended are used, the
VDC system may not operate prop-
erly and the VDC warning light
may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
NOTE:
. Always make sure the VDC is ON
before driving the vehicle by checking
that the VDC OFF indicator lights on
the meter and the VDC set-up switch
are not illuminated.
The GT-R is a high performance vehicle
and the VDC must be on/activated to
provide proper powertrain operation
and intended drivability.
WARNING
.The VDC OFF mode should ONLY be
used briefly to help free the vehicle
if stuck in snow or mud by tempora-
rily stopping operation of the VDC
to maintain wheel torque.
. Driving the GT-R with the VDC off
may lead to handling issues related
to steering maneuvers, acceleration,
or deceleration. Moreover, driving
with the VDC off can result in an
inoperative vehicle by causing ser-
ious damage to the powertrain,
including damage to the Transaxle
Assembly including Transfer, Clutch,
Gears, Transaxle case and all of its
components and other drivetrain
component(s) by overheating or ex-
cessive force.
. Damage to the powertrain or any
drivetrain component(s) that occurs
when there is a record in the Vehicle
Status Data Recorder (VSDR) that
the vehicle was driven with VDC off
during the period when the damage
was incurred is excluded from war-
ranty coverage.

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on t�fe side-
wall of all tires. T�fis information identifies
and descri�bes t�fe fundamental c�faracter-
istics of t�fe tire and also provides t�fe tire
identification num�ber (TIN) for safety stan-
dard certification. T�fe TIN can �be used to
identify t�fe tire in case of a recall.
Example
*1Tire size (example: P215/60R16 94H)
1.
P: T�fe “P” indicates t�fe tire is designed
for passenger ve�ficles. (Not all tires
�fave t�fis information.)
2.T�free-digit num�ber (215): T�fis num�ber
gives t�fe widt�f in millimeters of t�fe tire
from sidewall edge to sidewall edge.
3.Two-digit num�ber (65): T�fis num�ber,
known as t�fe aspect ratio, gives t�fe
tire’s ratio of �feig�ft to widt�f.
4.R: T�fe “R” stands for radial.
F: T�fe “F” after “R” indicates Self-
Supporting type run-flat tire.
5.Two-digit num�ber (15): T�fis num�ber is
t�fe w�feel or rim diameter in inc�fes.
6.Two- or t�free-digit num�ber (95): T�fis
num�ber is t�fe tire’s load index. It is a
measurement of �fow muc�f weig�ft eac�f
tire can support. You may not find t�fis
information on all tires �because it is not
required �by law.
7.H: Tire speed rating. You s�fould not
