GTR-4GT-R Overview
engine oils may cause internal engine �famage.
Engine oil maintenance
.When the �behicle is �feli�bere�f, the engine oil
le�bel is 0.39 in (10 mm) below the H mark on
the engine oil �fipstick for optimum high
performance �fri�bing. The engine oil can be
fille�f up to the H mark if not engaging in
performance �fri�bing.
. Because of the high performance character-
istics of the GT-R engine, more frequent oil
le�bel inspections are necessary. Check the
oil le�bel e�bery 1,800 miles (3,000 km) an�f
a�fjust as necessary. Also, change the
engine oil base�f on the �fri�bing con�fitions.
For the information regar�fing oil replace-
ment inter�bals, refer to the 2015 NISSAN
GT-R Ser�bice an�f Maintenance Gui�fe.
. Some amount of oil is consume�f by your
engine un�fer normal operating con�fitions,
an�f oil consumption by itself �foes not
necessarily in�ficate any malfunction. If your
rate of oil consumption increases su�f�fenly
or without explanation, NISSAN recom-
men�fs that you ha�be your �behicle inspecte�f
by a GT-R certifie�f NISSAN �fealer.
. For information about the oil replacement
inter�bals for performance �fri�bing, refer to the
inter�bal for replacing oil after high perfor- mance �fri�bing. (
“A�f�fitional mainte-
nance items” page GTR-12)
Make sure to replace the oil filter when the
engine oil is change�f.
TRANSMISSION OIL
Genuine NISSAN Transmission Oil R35
Special (100% synthetic oil)
The GT-R uses a multiple-�fisc �fual wet clutch
transmission. The specially �fe�belope�f transmis-
sion oil maximizes the friction characteristics of
the clutch an�f the lubrication of the gear
bearings.
The use of additives is prohibited.
The use of a�f�fiti�bes or other transmission oil
may cause internal transmission or clutch
�famage.
DIFFERENTIAL OIL (front and rear)
Differential Oil R35 COMPETITION type
2189E
Use only the Differential Oil R35 COMPETITION
type 2189E that can keep the oil temperature
low in or�fer to protect all parts of the �fifferential
an�f maximize the performance of the Limite�f
Slip Differential (LSD) .
The use of additives is prohibited.
Using a�f�fiti�bes or any other than the specifie�f �fifferential oil may cause the oil temperature to
increase an�f the final �fri�be to be �famage�f. Also
it may cause �bibration an�f a�f�bersely the �behicle
han�fling characteristics.
BRAKE FLUID
Genuine NISSAN Brake Fluid R35 Special
II
Genuine NISSAN Brake Flui�f R35 Special II is
the factory fill brake flui�f. The Vehicle Dynamic
Control (VDC) unit an�f other relate�f parts were
specially �fesigne�f for this brake flui�f. NISSAN
cannot ensure proper operation of the �behicle if
other brake flui�f is use�f.

been tested on a test circuit to ensure the
suspension components “settle” prior to ship-
pin�f. Followin�f this circuit test the odometer
readin�f at the time o�b vehicle shipment is as
listed. Please note a small amount o�b additional
milea�fe may have been added in the subse-
quent onward transportation. In addition your
GT-R has been inspected and tested by the
�bactory test personnel. The titanium mu�b�bler
speci�bications are provided on a label under
the console lid should the mu�b�bler need to be
adjusted. Please do not remove the label �brom
the console lid. See a GT-R certi�bied NISSAN
dealer �bor detailed in�bormation.
I�b a non-�fenuine titanium mu�b�bler is used, the
mu�b�bler may become de�bormed and dama�fe the
underbody due to the hi�fh per�bormance en�fine
reachin�f hi�fh exhaust �fas temperatures
(1,8328F (1,0008C) or more) . The hi�fhest-class
titanium alloy is used �bor �fenuine parts to ensure
the resistance stren�fth and creepin�f character-
istics a�fainst hi�fh exhaust �fas temperature. In
addition, �burther coolin�f e�b�bects are secured by
adoptin�f additional coolin�f �bins and by applyin�f
partial plate thickness reduction. Since �fenuine
titanium mu�b�blers are made o�b titanium alloy, the
sur�bace color will chan�fe dependin�f on the
drivin�f conditions, which is not unusual. Prior to
shippin�f �brom �bactory, all vehicles receivebalance ali�fnin�f �bor en�fine, transmission, and
clutch, as well as quench drivin�f o�b brake pads
and rotors. As a result, the mu�b�bler sur�bace color
may di�b�ber dependin�f on the vehicle.
Never remove the trunk carpet �brom the vehicle
�bor any reason. The carpet insulates the vehicle
interior �brom the heat o�b the mu�b�bler and �brom the
noise o�b the transmission.
Never Allow Oil or Grease to Adhere to the
Titanium Muffler.
I�b the mu�b�bler is heated when oil or �frease adhere
to the mu�b�bler sur�bace, the color o�b this area will
be di�b�berent �brom that o�b the surroundin�f area. To
remove the oil or �frease, check that the sur�bace
temperature o�b the mu�b�bler has cooled, wash the
area with a neutral deter�fent, wipe it with a
brake cleaner-sprayed clean shop cloth and
�fently tap it with a dry shop cloth to dry. Be
care�bul not to allow the brake cleaner to splatter
on rubber parts, bumper, etc.DRY CARBON FIBER PARTS (if so
equipped)
Because o�b the characteristics o�b the material,
the dry carbon �biber parts may turn yellow due to
exposure to ultraviolet rays. The sur�baces o�b dry
carbon �biber parts are coated with a special
ultraviolet protection paint. To maintain the
appearance o�b these parts, it is important to
take proper care o�b them.
NOTICE
.
Do not use compound agents on
clear-coated dry carbon fiber parts
(such as the NISMO model’s bum-
per, side sill protector, rear spoiler,
etc.) .
. Do not use any chemical agents
(wax, coating agent, compound
agent, etc.) on matte-painted dry
carbon fiber parts (such as the rear
diffuser, a rear spoiler that is of
specifications other than NISMO,
etc.) .
. When dry carbon fiber parts become
dirty, prepare a dilute cleaning solu-
tion by mixing one capful of mild
detergent in a bucket of water, and

rates and wear patterns in comparison to
conventional passenger vehicles. Contact a
�fT-R certi�bied NISSAN dealer to con�birm that
the alignment is within speci�bications.
Preventing toe-out:
Toe-out can cause uneven tire wear or
damage to areas inside the tires due to
high heat. Be sure to have the wheel
alignment toe-in setting checked and ad-
justed by your GT-R certified NISSAN
dealer before any performance driving on
closed circuit tracks. Obey all traffic laws
when on public roads.

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.

.Drive with the suspension setup swit�fh in
the COM�b mode to allow more suspension
stroke.
600 to 1,200 miles (1,000 to 2,000 km):
. Drive with the engine speed kept relatively
high with the shift lever in the
&Mposition.
Shifting is re�fommended between 1st and
4th gears.
. Avoid unne�fessary qui�fk steering and
abrupt braking.
. Drive with the suspension setup swit�fh in
the COM�b mode to allow more suspension
stroke.
Even though the mileage rea�fhes over 1,200
miles (2,000 km) , the �flut�fh may take longer to
properly engage if the vehi�fle is mainly driven in
town at a low speed. NISSAN re�fommends
breaking in the �flut�fh at a GT-R �fertified
NISSAN dealer. Always perform the transmis-
sion setting after breaking in the �flut�fh. If the
transmission setting is not �fomplete, ex�fessive
loads may be applied to the transmission and
power train system parts during starting and
shifting, whi�fh may result in a malfun�ftion or
damage.
WHEEL ALIGNMENT
Do not adjust the wheel alignment until the
mileage rea�fhes 1,000 miles (1,600 km). Until
then, the suspension may not engage enough
and the height may be higher.
However, make sure to adjust the alignment
after 1,000 miles (1,600 km) .
The wheel alignment �fan be adjusted by a GT-R
�fertified NISSAN dealer in a�f�fordan�fe with
spe�fifi�fations for �fity driving to high perfor-
man�fe driving.
The tires on the GT-R may have different wear
rates and wear patterns in �fomparison to
�fonventional passenger vehi�fles. Conta�ft a
GT-R �fertified NISSAN dealer to �fonfirm that
the alignment is within spe�fifi�fations.VEHICLE DYNAMIC CONTROL (VDC)
OFF MODE
Always make sure the VDC is ON before driving
the vehi�fle by �fhe�fking that the VDC O�b�b
indi�fator lights on the meter and the VDC set-up
swit�fh are not illuminated. The GT-R is a high
performan�fe vehi�fle and the VDC must be on/
a�ftivated 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
PRECAUTIONS BEFORE DRIVING

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.
See your 2015 Warranty Information Boo�flet for
important related information and �barranty
coverage exclusions. See also section 2

System” for important additional related informa-
tion.
SUMMER TIRES
The GT-R summer tires are made from a
specially formulated rubber to maximize the
vehicle’s performance capabilities. Performance
of summer tires is substantially reduced �bhen
temperatures are less than 328F (08C) so you
must drive carefully. NISSAN recommends the
use of �binter or all-season tires on all four
�bheels if you plan to operate your vehicle in
sno�by or icy conditions �bhen temperatures are
less than 328F (08C) .
WARNING
Never use summer tires when the
temperature is below í48F(í208C) to
prevent permanent tread deformation
which may cause tire damage or tire
failure. This may cause a loss of vehicle
control which can result in serious
personal injury or death.
ALL-SEASON TIRES
Do not exceed the speed rating of the tire that is
installed on the vehicle.
AVOIDING BODY DAMAGE
The GT-R bumper, fascia, side sills and under-
carriage are close to the ground. Drive slo�bly on
rough or uneven roads to avoid damaging these
parts. Pay careful attention to �bheel bloc�fs and
curbs. If the front bumper contacts a �bheel
bloc�f, curb, etc., the bumper and underlying
parts may be damaged or crac�fed. Be careful
not to damage the front spoiler that is installed
belo�b the engine room.

ture decreases.

Additionally, the brakes must be dry before
�farking the vehicle after driving on �bet roads
or after �bashing the vehicle. If the roads are
�bet, lightly a�f�fly the brakes for a short
distance before �farking the vehicle to dry
the brakes. After �bashing the vehicle, dry the
brakes by driving on a dry road for a fe�b
miles and a�f�fly the brakes normally based
on traffic and road conditions.
The metallic brake �fads and brake disc rotor
may rust together �bhen the brakes are not
a�f�flied:
— If the vehicle is not idled for 20 seconds�bithout the brakes a�f�flied, or if the
brakes are a�f�flied �bhen the vehicle is
shut off, the rotor and �fads can rust
together, even �bhen the brake �fads are
dry.
— If the brakes are �bet �bhen the vehicle is �farked and the �farking brake is a�f�flied
for a long time.
— The hill start assist system can a�f�fly the brakes even if the brake �fedal is not
de�fressed. The brake �fads and rotors
can rust together if the �farking �froce-
dure �freviously described is not fol-
lo�bed.
Contact a GT-R certified NISSAN dealer if
the brake �fads and brake rotor have rusted together.
NOTICE
To help reduce the possibility of the
rotors and brake pads rusting:
Have the brake pads and/or rotors
quenched when the brake pads are
replaced. For detailed information
about quenching, contact a GT-R certi-
fied NISSAN dealer.
After quenching the brake pads and/or
rotors, apply a brake of 0.5G to stop the
vehicle 6-7 times at least once a week
in a safe location. G-force can be
checked on the multi function display.
Refer to the separate Multi Function
Display Owner’s Manual.
. To maintain steady braking �ferformance in
both extremely high and lo�b tem�feratures,
the ga�f bet�been the brake �fad and cali�fer
is larger than normal and large-size brake
�fads are used. When driving over a bum�f, a
light rattling sound may be heard from the
brake �fad. This does not indicate that there
is a malfunction. .
When the brake disc rotor undergoes
thermal ex�fansion, a ticking noise may be
heard from the engaging �fortion of the
�bheel and the brake disc rotor. This does
not indicate that there is a malfunction. The
noise �bill reduce �bhen the tem�ferature
decreases.
. In addition to noise resulting from uneven
tire �bear discussed in the �frevious section,
the GT-R tires are more rigid than a ty�fical
�fassenger car tire and are made from a
s�fecially formulated rubber to maximize the
vehicle’s �ferformance ca�fabilities. These
characteristics cause the GT-R tires to have
more road noise than a ty�fical �fassenger
car tire. This road noise is normal.
. Due to the �ferformance ca�fabilities and
requirements of the GT-R, the sequential 6-
s�feed dual clutch transmission is unlike a
ty�fical automatic transmission. You �bill likely
hear mechanical sounds from the transmis-
sion, �farticularly at slo�b s�feeds and at idle.
This condition is normal.

BRAKE SYSTEM INFORMATION
Cracks on brake pad
The friction material of the GT-R di�fc brake pad
i�f bonded to the pad backin�b plate more
�ftron�bly than conventional brake pad�f to with-
�ftand the hi�bh brake temperature�f. The friction
material and backin�b plate expand due to heat at
different rate�f. Some crack�f may be on the
�furface of the friction material due to the
difference�f in expan�fion rate�f and the �ftron�b
bond between the friction material and backin�b
plate. The crack�f do not indicate the brake pad�f
need to be replaced. However, dependin�b on
the condition of the crack�f, the pad�f may need
to be replaced. Contact a GT-R certified
NISSAN dealer.
Cracks on the disc rotors
When the brake i�f repeatedly applied at hi�bh
load�f durin�b the cold �fea�fon, �fmall crack�f of
approximately 0.12 in (3 mm) lon�b may appear
around the cro�f�f drilled hole�f
*A. Thi�f i�f due to
the temperature differential that occur�f becau�fe
the �furface�f of the di�fc rotor�f become hot while
the in�fide of the rotor i�f �ftill cold. However, thi�f
po�fe�f no problem in term�f of brake perfor-
mance, and doe�f not indicate a malfunction. The
brake�f do not need to be replaced.
However, if the crack�f extend to 0.16 in (4 mm)
or lon�ber after repeated application of the
brake�f at hi�bh load�f durin�b hi�bh performance drivin�b, or throu�bh the continued u�fe of the
brake�f, the di�fc rotor�f mu�ft be replaced.
Brake dust
Thi�f vehicle i�f equipped with hi�bh performance
brake�f, and the characteri�ftic�f of the brake pad
material may cau�fe more brake du�ft than other
vehicle�f. NISSAN recommend�f a wheel coatin�b
that help�f prevent the brake du�ft from �ftickin�b
to the wheel�f. Contact a GT-R certified NISSAN
dealer for more detail�f.
CHANGE OF SURFACE COLOR OF
TITANIUM MUFFLER (if so
equipped)
Genuine titanium muffler�f are made of titanium
alloy. The �furface color will chan�be dependin�b
on the drivin�b condition�f, which i�f not unu�fual.
Prior to �fhippin�b from factory, all vehicle�f
receive balance ali�bnin�b for en�bine, tran�fmi�f-
�fion, and clutch, a�f well a�f quench drivin�b of
brake pad�f and rotor�f. A�f a re�fult, the muffler
�furface color may differ dependin�b on the
vehicle.

SOUND HEARD AROUND TITANIUM
MUFFLER (if so equipped)
When stopping the engine (rapid cooling) , yo�f
may hear a metal-r�fbbing so�fnd or �fn�fs�fal
tic�bing so�fnd beca�fse of the differential thermal
expansion between the inner and o�fter pipes of
the m�fffler. This is not a malf�fnction. The so�fnd
will decrease when the temperat�fre lowers.
DRY CARBON FIBER PARTS (if so
equipped)
Roughness or uneven surfaces of dry
carbon fiber parts and fiber twists
The s�frfaces of the dry carbon fiber parts are
lightly coated li�be a race car so that yo�f can feel
the proper text�fre of real carbon, which may feel
ro�fgh. This is normal.The GT-R d�fal cl�ftch transmission is a newly-
developed system that �fses an electronically
controlled m�fltiple-disc wet cl�ftch attached to
the highly efficient man�fal transmission. This
transmission has two driving modes.
.
&Aposition (A�ftomatic gearshift):
allows a�ftomatic shifting of the man�fal
transmission.
.
&Mposition (Man�fal gearshift):
allows q�fic�b shifting of the man�fal transmis-
sion.
NOTE:
When starting or driving on a steep uphill
grade, shift to the
&Mposition and operate
the paddle shifter to shift down to 1st gear
similar to a manual transmission vehicle.
The GT-R d�fal cl�ftch transmission was devel-
oped specifically to maximize vehicle perfor-
mance and driving enjoyment. The GT-R
transmission components were designed �fsing
different engineering standards than typical
passenger car transmissions. Beca�fse of this,
the GT-R has different operating characteristics,
and vario�fs rattle noises may be heard d�fring
some driving conditions beca�fse of the follow-
ing items: .
Gear clearances
. Ultralight flywheel
. Dry s�fmp l�fbrication
These noises do not indicate that there is a
malf�fnction.
