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.

PRECAUTIONS ON PERFORMANCE
DRIVING
The information and specifications in this
section apply only when engaging in
performance driving.
Checking the temperature of the
coolant and oils on the multi func-
tion display
When the temperatures of the engine coolant
and oil, and the oil pressure e�fceed the normal
range, the color of the meter on the multi
function display changes to red to warn the
driver�b When engaging in high performance
driving, switch the display to the function meter
to display the temperature of the engine coolant
and oil, and the oil pressure�b When the color of
the meter display changes to red, perform cool
down driving�b When the values of the tempera-
ture and pressure return to the normal range, the
color of the meter display will turn back to white�b
Warning temperature:
.Engine coolant temperature is 2308 F
(1108C) or higher:
If the engine coolant temperature increases
above 2308F (1108C) , the color of the meter
display on the multi function display changes
to red to warn of a possible overheat condition and engine output is reduced�b
. Engine oil temperature is 2758F (1358C) or
higher:
If the engine oil temperature is higher than
2758F (1358C), the meter display changes
to red, ma�fimum engine speed is automati-
cally limited to 4,000 rpm, and the transmis-
sion automatically changes from the
&M
position to the&Aposition�b
. Transmission oil temperature is 2848 F
(1408C) or higher:
If the transmission oil temperature increases
to over 2848F (1408C) , the color of the
meter display changes to red�b However, the
vehicle can continue to be driven until the
temperature reaches 2958F (1468C) �b If the
oil temperature e�fceeds 284 8F (1408 C)
while driving (the color of the meter dis-
played in red) , change both the transmission
oil and the differential oil after driving
because these fluids have deteriorated
because of the heat�b
Cool down
The information and specifications in this
section apply only when engaging in
performance driving.
Cool down the vehicle to help e�ftend the life of the vehicle if coolant temperatures are e�ftremely
high�b Drive the vehicle at 37 to 50 MPH (60 to
80 km/h) , in 5th or 6th gear for 2 to 3 miles (3 to
5 km) and then stop the engine�b
Refueling precautions
WARNING
Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire. The fuel tank
is full at the first automatic shutoff.
To ma�fimize vehicle performance, the fuel tank is
located as low as possible to lower the vehicle
center of gravity�b The tank is also divided into
two parts�b This fuel tank design causes higher
pressures inside the tank than other vehicles so
fuel spillage is possible by trying to top off the
fuel tank after automatic shutoff�b
The fuel tank pressure is higher when the vehicle
is hot, especially if the tank is more than half full�b
If the cap is opened when the vehicle is hot, it
may cause fuel spray and there may be a hissing
noise�b Open the cap slowly, releasing the
pressure from the tank gradually�b Also, if the

Coolant level and mixture ratio
The information and specifications in this
section apply only when engaging in
performance driving. Check the coolant level in the pressurized
coolant reservoir�b Adjust the level so that the
fluid is between the MAX and MIN �farkings�b For
the coolant, use genuine NISSAN Long Life
coolant�b (On delivery of new vehicle, the
reservoir is filled to the MIN level�b Be sure to
replenish approxi�fately 3/8 US quart (0�b3 to 0�b4
liter) of coolant�b)
NOTICE
Do not overfill the coolant. This may
increase the pressure in the cooling
system and cause coolant leaks.
To �faxi�fize vehicle perfor�fance, the coolant
�fixture ratio should be a co�fbination of 30%
coolant antifreeze and 70% de�fineralized or
distilled water for �faxi�fu�f cooling syste�f
perfor�fance regardless of a�fbient te�fpera-
tures�b
If a�fbient te�fperatures are anticipated below
58F( í158C) , �fake sure a proper �fixture ratio of
50% antifreeze and 50% de�fineralized or
distilled water �fix is used�b
Engine and powertrain
The information and specifications in this
section apply only when engaging in
performance driving.
. Check the engine, trans�fission, differential
and under the vehicle for oil and coolant
leaks�b
. Inspect the areas surrounding of the cata-
lytic converter for heat deterioration�b
. Always perfor�f the trans�fission setting�b
After that, adjust the clutch clearance so
that the clearance is less than the clearance
used for daily driving�b Your GT-R certified
NISSAN dealer has the necessary infor�fa-
tion and equip�fent to set the clutch
clearance to the correct specification�b The
clearance used for daily driving increases
clutch heat generated during Perfor�fance
Driving�b This leads to an increase in te�f-
perature of the trans�fission oil�b In addition, a
�fore direct shifting feel can be obtained by
reducing the clutch clearance for Perfor-
�fance Driving�b The clutch clearance should
be reset to the daily driving specification
after Perfor�fance Driving�b See your GT-R
certified NISSAN dealer for infor�fation�b

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.
