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

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.
Fluids
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.

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

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
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.
GASOLINE SMELL
The fuel temperature is higher when the vehicle
is hot. This may cause a gasoline smell from the
vehicle. This does not indicate that there is a
malfunction. The smell will go away when the
fuel temperature has cooled.
OUTSIDE TEMPERATURE DISPLAY
INDICATES HIGHER TEMPERATURE
Heat from the engine compartment, radiator and
intercoolers can affect the outside temperature
display. The outside temperature display may
indicate a higher than actual temperature while
driving or stopped. This is normal.
IDLE SPEED IS NOT STEADY
The idle speed may not be steady when the
engine compartment is extremely hot. This is
normal. The engine speed will be steady when
the engine cools down.
In this case, the Malfunction Indicator Light (MIL)
may come on. After a few driving trips, the MIL
should turn off. If the light remains on after a few
driving trips, have the vehicle inspected by a
GT-R certified NISSAN dealer.
ENGINE SPEED IS RESTRICTED
To help protect the engine, the maximum engine
speed is automatically controlled in the following
conditions:
.
Revving the engine with the shift lever in the
&Por&Nposition: The maximum engine
speed is 5,000 RPM
. Revving the engine when the engine oil is at
a low (below 328F(0 8C)) or extremely high
(over 2758 F (1358C)) temperature: The
maximum engine speed is 4,000 RPM (The
&Mposition will automatically change to the
&Aposition.)
ENGINE OUTPUT
High altitude
To protect the engine, engine output is con-
trolled so that it does not increase at altitudes
4,922 ft (1,500 meters) or higher.
Engine output according to the
coolant temperature
The engine output is controlled at a low level
when the engine coolant temperature is lower
than approximately 1588F (708C) or higher than
2308F (1108C). This is not a malfunction.
If the temperature is lower than approximately
GT-R SPECIFIC VEHICLE
CHARACTERISTICS
1588F (708C) , drive the vehicle until it reaches
normal operating temperature. If the temperature
is higher than 2308F (1108C), perform cool-
down driving procedure. (
“Cool down”
page GTR-13) When the temperature of the
engine coolant is between 1588F (708C) and
2308F (1108C) , the engine output returns to
normal.
DISTORTION OF REAR SPOILER
When the vehicle is parked in direct sunlight on
a hot day, the center of the rear spoiler may
become distorted. This is normal. When the
surface temperature of the rear spoiler is
reduced, the shape of the spoiler should return
to normal.
UNEVEN WEAR OF TIRES
The GT-R is equipped with high performance,
low profile, run-flat tires that are optimized for
performance and handling. The life of these tires
will be less than those of tires installed on a
typical vehicle, and you are likely to experience
uneven tire wear and tire noise regardless of the
type of tire used.
NOISES ARE HEARD WHILE DRIV-
ING
. The GT-R brake pads use material that
provides a high amount of braking power
even in high temperatures. This material can
cause an intermittent screeching noise just
before the vehicle comes to a stop when the
brakes are gently applied. The noise de-
creases as the brake pads wear. However,
the additional brake pad break-in or repla-
cing the cross spring may decrease the
noise. Contact a GT-R certified NISSAN
dealer.
. A screeching noise may be heard when the
brake pedal is depressed:
— When driving the vehicle for the first time
in the morning,
— After leaving the vehicle parked for extended periods of time, or
— When the vehicle is damp following rain showers or washing the vehicle.
These sounds are normal. The noise is
caused when the brake pads absorb moist-
ure, and the noise stops after the brake is
applied several times.
. A screeching noise may also be heard when
the brake pedal is depressed: — When repeatedly applying gentle brak-
ing, especially on a curve at a low speed,
or
— When the brake rotors have circular scores with the brake temperature high.
WARNING
Follow the instructions below when
parking the vehicle to help prevent the
brake rotor and brake pads from rust-
ing together. Failure to follow the
instructions could cause the rotor and
pads to rust together. If the rotor and
pads rust together, there may be a
popping noise and some vibration
when the vehicle is driven, a wheel
may not roll correctly, or the brake pads
could be damaged. If the pads are
damaged, this may reduce the effec-
tiveness of the brake system which
could cause a collision, serious perso-
nal injury or death.
. The GT-R uses brake pad materials that
have high metallic content. The brake pad
material helps maintain braking performance
in a wide range of weather and driving
conditions.
GT-R OverviewGTR-25
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.
