NOTICE
Only use the following specified fluids
and parts in the GT-R to avoid possible
vehicle damage.
ENGINE OIL
Mobil 1 (0W-40) (100% synthetic oil)
Mobil 1 (0W-40) (100% synthetic) is the factory
fill oil. The VR38 engine with its plasma-sprayed
bores was developed using this oil. NISSAN
cannot ensure proper engine operation and
durability if other synthetic oil is used. If Mobil
1 (0W-40) is not available, Mobil 1 (10W-40)
(100% synthetic) may be used; however, some
performance loss may be noticed.
Furthermore, replacement of the engine oil with
MOTUL NISMO COMPETITION OIL type
2193E(5W40) is recommended for the frequent
high performance driving opportunities or when
the engine starting ability during cold weather is
a concern.
NISSAN cannot ensure proper engine operation
and durability if other synthetic oil is used.
The use of additives, chemical materials or
abrasive compounds is prohibited.The use of additives, chemical materials, abra-
sive compounds or other high performance
engine oils may cause internal engine damage.
Engine oil maintenance
.
When the vehicle is delivered, the engine oil
level is 0.39 in (10 mm) below the H mark on
the engine oil dipstick for optimum high
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 2014 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-13)
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
GT-R SPECIAL SPECIFICATION
PARTS

ENGINE SETTINGS (balancing right
and left air flow)
Each cylinder bank of this engine operates
independently due to the vehicle’s twin turbo-
charger design. Each side of the engine must
operate at the same level of performance. The air
flow of each bank must be checked and
adjusted as necessary by a GT-R certified
NISSAN dealer.
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. If the
transmission setting is not complete, excessive
loads may be applied to the transmission and
power train system parts during starting and
shifting, which may result in a malfunction or
damage. Depending 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 tocontrol 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.
GT-R OverviewGTR-9
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. Always perform the transmis-
sion setting after breaking in the clutch. If the
transmission setting is not complete, excessive
loads may be applied to the transmission and
power train system parts during starting and
shifting, which may result in a malfunction or
damage.
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 2014 Warranty Information Booklet for
important related information and warranty
coverage exclusions. See also section 2
(
“Transmission warning light” page 2-30)
and section 5 (“Vehicle Dynamic Control
(VDC) system” 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.

GTR-16GT-R Overview
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.
. Always perform the transmission setting.
After that, adjust the clutch clearance so
that the clearance is less than the clearance
used for daily driving. Your GT-R certified
NISSAN dealer has the necessary informa-
tion and equipment to set the clutch
clearance to the correct specification. The
clearance used for daily driving increases
clutch heat generated during Performance
Driving. This leads to an increase in tem-
perature of the transmission oil. In addition, a
more direct shifting feel can be obtained by
reducing the clutch clearance for Perfor-
mance Driving. The clutch clearance should
be reset to the daily driving specification
after Performance Driving. See your GT-R
certified NISSAN dealer for information.
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) .
. Inspect the dust boot of the drive shaft
universal joint for cracks or damage.
Suspension and wheel alignment
The information and specifications in this
section apply only when engaging in
performance driving.
.Check the steering and suspension system
and other links for loose and/or damaged
parts.
. Measure and adjust the wheel alignment.
(
“Wheel alignment” page GTR-10)
Contact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the recom-
mended setting for high performance driv-
ing. 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.
Toe-in specification

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-
17) If you do not drive under the conditions
listed in this section, see (
“Wheels and
tires” page 8-32)
. 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 8-32)
. 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
GTR-17)
. 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) .
GT-R OverviewGTR-23

.Due to the performance capabilities and
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 FIBER CARBON PARTS (if so
equipped)
Roughness or uneven surfaces of dry fiber
carbon parts and fiber twists
The surfaces of the dry fiber carbon parts 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.
