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 exceed the normal
range, the color of the meter on the multi
function display changes to red to warn the
driver. 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. When the color of
the meter display changes to red, perform cool
down driving. 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.
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.
. Engine oil temperature is 2758F (1358C) or
higher:
If the engine oil temperature is higher than
2758F (1358C), the meter display changes
to red, maximum engine speed is automati-
cally limited to 4,000 rpm, and the transmis-
sion automatically changes from the
&Mposition to the&Aposition.
. 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. However, the
vehicle can continue to be driven until the
temperature reaches 2958F (1468C) . If the
oil temperature exceeds 2848 F (1408C)
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.
Cool down
The information and specifications in this
section apply only when engaging in
performance driving.
Cool down the vehicle to help extend the life of the vehicle if coolant temperatures are extremely
high. 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.
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 maximize vehicle performance, the fuel tank is
located as low as possible to lower the vehicle
center of gravity. The tank is also divided into
two parts. 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.
The fuel tank pressure is higher when the vehicle
is hot, especially if the tank is more than half full.
If the cap is opened when the vehicle is hot, it
may cause fuel spray and there may be a hissing
noise. Open the cap slowly, releasing the
pressure from the tank gradually. Also, if the
GT-R OverviewGTR-13

GTR-14GT-R Overview
vehicle is refueled when the vehicle is hot, the
fuel pump may automatically shut off before the
tank is full. This does not indicate that there is a
malfunction. Refuel slowly or refuel after the
vehicle has cooled.
INSPECTION AND ADJUSTMENTS
BEFORE DRIVING
The information and specifications in this
section apply only when engaging in
performance driving.
Fluids
.Check the engine, transmission, differential
and under vehicle surfaces for oil and
coolant leaks.
. Check the fluid levels and adjust as neces-
sary using the specified fluid as described
under the conditions listed in this section.
(
“Recommended fluids and mainte-
nance interval” page GTR-20 ) If you do
not drive under the conditions listed, refer to
the 2013 NISSAN Service and Maintenance
Guide.
. NISSAN recommends to adjust the engine
oil level
*1to be 0.39 in (10 mm) (1/8 gal
(0.5 liters))
*2below the H mark on the
engine oil dipstick. (
*3range is 1.18 in (30
mm)) Before checking the oil level, run the
engine until it reaches operating tempera-
ture and wait at least 5 minutes after turning
off the engine. Make sure the oil level always
remains above the L mark.
When the vehicle is delivered, the engine oil
is set to “H- 0.39 in (10 mm)” for optimal
high performance driving.
. 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.

.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) .

the wheels. The tire may slip on the wheel if
the vehicle is driven in these conditions
before 48 hours have passed. If the tire slips
on the wheel, the wheel/tire assembly will be
out of balance and will require rebalancing.
Brakes
The information and specifications in this
section apply only when engaging in
performance driving.
.Check for the heat deterioration of the
brakes and parts around the brakes.
. It is recommended that you remove air from
the brake system after any of the following:
— When engaging in high performance
driving for the first time after purchasing
a new vehicle.
— After replacing the brake fluid.
— When engaging in high performance driving for a sustained period of time. It
is recommended that bleeding the brake
be performed when the brake calipers
are hot (about 2128F (1008C)) .
Brake pad:
NISSAN recommends adding an additional
cross spring to the front calipers before enga-
ging in performance driving. The additional
spring reduces brake pad movement resulting from cornering forces and will reduce the stroke
of the brake pedal. Contact a GT-R certified
NISSAN dealer to purchase the spring and
arrange installation. If a cross spring is added, a
clattering or squeaking sound may be heard on
rare occasions.
Brake pad break-in procedure:
NISSAN recommends that a special brake pad
break-in procedure be performed before enga-
ging in performance driving. Contact a GT-R
certified NISSAN dealer for details.
INSPECTION AND ADJUSTMENTS
AFTER DRIVING
The information and specifications in this
section apply only when engaging in
performance driving.
NOTICE
At the completion of performance driv-
ing, all fluid and other adjustments
should be returned to the normal fluid
specifications as shown in the “Main-
tenance and do-it-yourself” section of
this manual.

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
GTR-16)
. 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.
