performance driving. The engine oil can be
filled up to the H mark if not engaging in
performance driving.
. Because of the high performance character-
istics of the GT-R engine, more frequent oil
level inspections are necessary. Check the
oil level every 1,800 miles (3,000km) and
adjust as necessary. Also, change the
engine oil based on the driving conditions.
For the information regarding oil replace-
ment intervals, refer to the 2013 NISSAN
GT-R Service and Maintenance Guide.
. Some amount of oil is consumed by your
engine under normal operating conditions,
and oil consumption by itself does not
necessarily indicate any malfunction. If your
rate of oil consumption increases suddenly
or without explanation, NISSAN recom-
mends that you have your vehicle inspected
by a GT-R certified NISSAN dealer.
. For information about the oil replacement
intervals for performance driving, refer to the
interval for replacing oil after high perfor-
mance driving. (
“Additional mainte-
nance items” page GTR-12)
Make sure to replace the oil filter when the
engine oil is changed.
TRANSMISSION OIL
Genuine NISSAN Transmission Oil R35
Special (100% synthetic oil)
The GT-R uses a multiple-disc dual wet clutch
transmission. The specially developed transmis-
sion oil maximizes the friction characteristics of
the clutch and the lubrication of the gear
bearings.
The use of additives is prohibited.
The use of additives or other transmission oil
may cause internal transmission or clutch
damage.
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 order to protect all parts of the differential
and maximize the performance of the Limited
Slip Differential (LSD) .
The use of additives is prohibited.
Using additives or any other than the specified
differential oil may cause the oil temperature to
increase and the final drive to be damaged. Also
it may cause vibration and adversely the vehicle
handling characteristics.
BRAKE FLUID
Genuine NISSAN Brake Fluid R35 Special
II
Genuine NISSAN Brake Fluid R35 Special II is
the factory fill brake fluid. The Vehicle Dynamic
Control (VDC) unit and other related parts were
specially designed for this brake fluid. NISSAN
cannot ensure proper operation of the vehicle if
other brake fluid is used.
TIRES AND ROAD WHEELS
Genuine GT-R tires and road wheels
Use only genuine GT-R tires and road wheels.
Tires
The GT-R uses specially designed run-flat tires
and matching road wheels. Use of these
specially developed tires and wheels provides
the greatest potential for maximum performance.
. Using non-genuine GT-R tires may cause
powertrain system damage if the vehicle is
driven in a flat tire situation, even if run-flat
tires are used. This may also prevent the
vehicle from being stopped safely.
. Using non-genuine GT-R tires may also
cause tire failure due to excessive heat
buildup caused by tire distortion while
driving.

TRANSMISSION SETTINGS
The design of the clutch and transmission
requires inspection and adjustment of the clutch
and shift forks by a GT-R certified NISSAN
dealer at the recommended intervals. Depend-
ing on the driving conditions, more frequent
adjustments may be necessary to help maximize
vehicle performance.
CHECKING THE EXHAUST FIN-
ISHER AND REAR BUMPER
CLEARANCE
Clearance between the enlarged-diameter ex-
haust finisher and the rear bumper is realized by
using highly rigid exhaust mount rubber to
control rear muffler vibration. The clearance
between the exhaust finisher and the rear
bumper may alter as the exhaust mount rubber
changes shape due to vibration, passage of time
and high exhaust temperature during high
performance driving. Therefore, inspection of
the clearance is necessary during the GT-R
special inspection and when engaging in
performance driving.
INCREASE TIGHTENING OF THE
STRUT SUPPORT BAR ATTACH-
MENT SECTION WITH THE SHOCK
ABSORBER
During the first GT-R special inspection (after
1,000 miles) , the strut support bar attachment
bracket and shock absorber (each one on the
left and right sides) must be tightened to the
specified tightening specification. The strut
support bar attachment bracket and shock
absorber (each one on the left and right sides)
must be tightened to the specified tightening
specification 300-600 miles (500-1,000 km)
after the support bar or shock absorber have
been removed or installed.

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 following types of driving
until the mileage shown below has been
reached.
Until 300 miles (500 km):
. Do not depress the accelerator pedal more
than halfway 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 fully
depressed. Depress the pedal slowly.
. Avoid unnecessary quick steering and
abrupt braking.

BREAK-IN SCHEDULE

GTR-10GT-R Overview
.Drive with the suspension setup switch in
the COMF 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 recommended between 1st and
4th gears.
. Avoid unnecessary quick steering and
abrupt braking.
. Drive with the suspension setup switch in
the COMF mode to allow more suspension
stroke.
Even though the mileage reaches over 1,200
miles (2,000 km) , the clutch may take longer to
properly engage if the vehicle is mainly driven in
town at a low speed. NISSAN recommends
breaking in the clutch at a GT-R certified
NISSAN dealer.
WHEEL ALIGNMENT
Do not adjust the wheel alignment until the
mileage reaches 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 can be adjusted by a GT-R certified NISSAN dealer in accordance with
specifications for city driving to high perfor-
mance driving.
The tires on the GT-R may have different wear
rates and wear patterns in comparison to
conventional passenger vehicles. Contact a
GT-R certified NISSAN dealer to confirm that
the alignment is within specifications.
VEHICLE DYNAMIC CONTROL (VDC)
OFF MODE
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
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 2013 Warranty Information Booklet for
important related information and warranty
coverage exclusions. See also section 2 (page
2-29) and section 5 (page 5-49) of this Owner’s
Manual, “Transmission Clutch Temperature
High” and “Vehicle Dynamic Control (VDC)
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 when
temperatures are less than 328F(0 8C) so you
must drive carefully. NISSAN recommends the
use of winter or all-season tires on all four
wheels if you plan to operate your vehicle in snowy or icy conditions when temperatures are
less than 328F(0
8C) .
WARNING
Never use summer tires when the
temperature is below −48F(−208C) 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 slowly on
rough or uneven roads to avoid damaging these
parts. Pay careful attention to wheel blocks and
curbs. If the front bumper contacts a wheel
block, curb, etc., the bumper and underlying
parts may be damaged or cracked. Be careful
not to damage the aerodynamic diffuser that is
installed below the engine room.

.Adjust the power steering fluid level to the R
mark
*5on the power steering dipstick
when the fluid temperature is hot or
*6when the fluid temperature is cold.
Fluid temperature:
Hot: 122 to 1768F (50 to 808C): between
*1and*5
Cold: 32 to 868F(0to30 8C): between*3and*6
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. Adjust the level so that the
fluid is between the MAX and MIN markings. For
the coolant, use genuine NISSAN Long Life
coolant. (On delivery of new vehicle, the
reservoir is filled to the MIN level. Be sure to
replenish approximately 3/8 US quart (0.3 to 0.4
liter) of coolant.)
NOTICE
Do not overfill the coolant. This may
increase the pressure in the cooling
system and cause coolant leaks.
To maximize vehicle performance, the coolant
mixture ratio should be a combination of 30%
coolant antifreeze and 70% demineralized or
distilled water for maximum cooling system
performance regardless of ambient tempera-
tures.
If ambient temperatures are anticipated below
58F( −158C) , make sure a proper mixture ratio of
50% antifreeze and 50% demineralized or distilled water mix is used.
Engine and powertrain
The information and specifications in this
section apply only when engaging in
performance driving.
.
Check the engine, transmission, differential
and under the vehicle for oil and coolant
leaks.
. Inspect the areas surrounding of the cata-
lytic converter for heat deterioration.
. Before engaging in performance driving,
appropriate clutch adjustment must be
performed by your GT-R certified NISSAN
dealer.
NOTICE
Failure to have the clutch properly
adjusted before performance driving
may cause the transmission oil tem-
perature to increase which may cause
transmission damage.
. Inspect and confirm the clearance between
the exhaust finisher and rear bumper is more
than 0.24 in (6 mm) (up/down) and more
than 0.20 in (5 mm) (left/right) .
GT-R OverviewGTR-15

Suspension and wheel alignment
.Check the steering and suspension system
and other links for loose and/or damaged
parts.
. Measure and adjust the wheel alignment.
Contact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the recom-
mended setting for normal driving.
Wheels and tires
.Check tire wear and cracking.
. Inspect the tire side wall for damage.
. Check the tire pressure and adjust the
pressure as necessary when the tires are
cold. (
“Wheels and tires” page GTR-
16) If you do not drive under the conditions
listed in this section, see (
“Wheels and
tires” page 8-31)
. Check that the wheel nuts are not stripped.
Check if there is no deformation on the
contact surface of the wheel nuts.
. Make sure the wheel nuts are tight.
(
“Wheels and tires” page 8-31)
. Make sure the drive shaft nuts are tight.
. Check wheel hub run out and that the wheel
rotates smoothly without any friction. Check
these with the tires removed whenever an inspection is performed with the vehicle
jacked up.
. Make sure the tire has not slipped on the
wheel causing the assembly to be out of
balance. The reference marks on the tire and
wheel should be aligned. If the reference
marks are not aligned, the tire has slipped on
the wheel. Have the wheels/tires reba-
lanced. Make sure the old reference marks
are erased and new reference marks are
applied to the wheel and tire. When instal-
ling new tires on the wheels, make sure new
reference marks are applied to the wheels
and tires. (
“Wheels and tires” page

. Make sure that the TPMS sensor installation
nuts and the sensor valve are tight and there
is no nitrogen leak.
Brakes
.Check for the heat deterioration of the
brakes and parts around the brakes.
. Check the condition of the brake pads and
disc rotors and replace them as necessary.
Engine and powertrain
.Check the engine, transmission, differential
and under the vehicle for oil and coolant leaks.
. Inspect the area surrounding the catalytic
converter for heat deterioration.
. Inspect and confirm the clearance between
the exhaust finisher and rear bumper is more
than 0.24 in (6 mm) (up/down) and more
than 0.20 in (5 mm) (left/right) .
. The clutch clearance and shift fork position
may need to be adjusted.
. Inspect the dust boot of the drive shaft
universal joint for cracks or damage.
. Check that there is no abnormal noise,
vibrations or warning lights illuminated when
making tight turns at slow speed (for tight
corner braking phenomenon) .

requirements of the GT-R, the sequential 6-
speed dual clutch transmission is unlike a
typical automatic transmission. You will likely
hear mechanical sounds from the transmis-
sion, particularly at slow speeds and at idle.
This condition is normal.
BRAKE SYSTEM INFORMATION
Cracks on brake pad
The friction material of the GT-R disc brake pad
is bonded to the pad backing plate more
strongly than conventional brake pads to with-
stand the high brake temperatures. The friction
material and backing plate expand due to heat at
different rates. Some cracks may be on the
surface of the friction material due to the
differences in expansion rates and the strong
bond between the friction material and backing
plate. The cracks do not indicate the brake pads
need to be replaced. However, depending on
the condition of the cracks, the pads may need
to be replaced. Contact a GT-R certified
NISSAN dealer.
Cracks on the disc rotors
When the brake is repeatedly applied at high
loads during the cold season, small cracks of
approximately 0.12 in (3 mm) long may appear
around the cross drilled holes
*A. This is due to
the temperature differential that occurs because
the surfaces of the disc rotors become hot while
the inside of the rotor is still cold. However, this
poses no problem in terms of brake perfor-
mance, and does not indicate a malfunction. The
brakes do not need to be replaced.
However, if the cracks extend to 0.16 in (4 mm)
or longer after repeated application of the
brakes at high loads during high performance driving, or through the continued use of the
brakes, the disc rotors must be replaced.
Brake dust
This vehicle is equipped with high performance
brakes, and the characteristics of the brake pad
material may cause more brake dust than other
vehicles. NISSAN recommends a wheel coating
that helps prevent the brake dust from sticking
to the wheels. Contact a GT-R certified NISSAN
dealer for more details.
DRY CARBON FIBER REAR SPOI-
LER (if so equipped)
The surfaces of the dry carbon fiber rear spoiler
are lightly coated like a race car so that you can
feel the proper texture of real carbon, which may
feel rough. This is normal.
GT-R OverviewGTR-27

GTR-28GT-R Overview
The GT-R dual clutch transmission is a newly-
developed system that uses an electronically
controlled multiple-disc wet clutch attached to
the highly efficient manual transmission. This
transmission has two driving modes.
.
&Aposition (Automatic gearshift):
allows automatic shifting of the manual
transmission.
.
&Mposition (Manual gearshift):
allows quick shifting of the manual 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 dual clutch transmission was devel-
oped specifically to maximize vehicle perfor-
mance and driving enjoyment. The GT-R
transmission components were designed using
different engineering standards than typical
passenger car transmissions. Because of this,
the GT-R has different operating characteristics,
and various rattle noises may be heard during
some driving conditions because of the follow-
ing items:
. Gear clearances .
Ultralight flywheel
. Dry sump lubrication
These noises do not indicate that there is a
malfunction.
DUAL CLUTCH TRANSMISSION

TRANSMISSION OPERATION CHARACTERISTICS
MechanismOperation characteristics
Base Manual transmission
.The GT-R transmission design is different from transmissions used in conventional passenger cars. The GT-R uses a transmission gear
design, light flywheel and a dry sump lubrication system to provide maximum vehicle performance. Because the GT-R Transmission design
is different, noises may be louder. When the transmission temperature is high, rattling, shaking and jarring noises may be heard.
.Clattering noises may be heard while shifting..Appropriate gaps are provided between gears to achieve smooth gear rotation and steady tooth surface lubrication under the high-load
driving condition. However, this causes a rattling noise.
.If the shift lever is moved from&Rto&A↔&Mposition, or&A↔&Mto&Rposition before the vehicle stops, you may not be able to shift gear
or it may take longer to shift gear. Make sure to depress the brake pedal and check that the vehicle has stopped before shifting.
Multiple disc wet clutch
.When stopping the vehicle with the shift lever in the&Ror&A↔&Mposition, be sure to firmly depress the brake pedal. The vehicle may
slowly move if the brake pedal is not depressed.
.Avoid depressing the brake and accelerator pedals at the same time. Depressing the brake and accelerator pedals at the same time could
cause the clutch to overheat and accelerate deterioration.
.When the vehicle is stopped on a hill, do not hold the vehicle in place by depressing the accelerator pedal. Doing so may cause the clutch
to overheat and result in transmission damage. Use the brakes to prevent the vehicle from moving.
Electronic oil pressure
control The following conditions are caused due to changes in fluid viscosity as a result of temperature changes.
.When the transmission oil is extremely cold or extremely hot, the transmission may feel like it is slipping during shifts or there may be hard
shifts. This is normal. Transmission shifting should return to normal when the transmission oil returns to normal operating temperatures.
.When the transmission oil temperature is extremely cold, the time required to run a system check may increase. During the system check,
the shift lever must stay in the&Pposition. Move the shift lever after turning off the system check display. Also, it is normal to hear clicking
noises during the transmission systems check.
Changing modes
.The higher shift speeds in the&Mposition may result in shift shock and jerkiness when starting or shifting..The quickest shifting in the R mode with the transmission in the&Mposition is available when the engine speed is high. However, the
transmission may shift more slowly when the engine speed is low.
Mechanical Limited Slip
Differential (LSD) If the vehicle accelerates from a stop with the steering wheel turned half a turn in cold temperatures, the inner wheel tire may slip and some
noise or vibration may be heard. This phenomenon occurs because the viscosity of the differential oil becomes thicker and the Limited Slip
Differential (LSD) operates with increasing load. When the steering wheel is returned to the straight ahead position or the differential oil warms
up, the noise and vibration decrease.
