GTR-6GT-R Overview
performed when a GT-R certified technician
determines that this is the correct repair.
If the inside of the disc rotors are cold during the
winter and the surface becomes hot due to a
heavy force being applied repeatedly to the
brakes, cracks may occur near the coolant hole
on the surface of the disc rotor. Cracks may also
occur due to a heavy force being repeatedly
applied to the brakes during high performance
driving. In these cases it may be necessary to
replace the disc rotors or brake pads depending
on the condition of the crack. Contact a GT-R
certified NISSAN dealer for replacement.
EXHAUST MUFFLER AND TRUNK
CARPET
Genuine GT-R special exhaust muffler and
trunk carpet.
Use only the genuine GT-R special exhaust
muffler and trunk carpet.
The GT-R exhaust system is designed to provide
the maximum vehicle performance and to
protect the vehicle from high exhaust gas
temperatures.
If non-genuine GT-R specification parts are
used it is possible that the muffler or other
exhaust system parts will deform and cause
damage to the underbody. Non-genuine GT-Rspecification parts can also affect vehicle
performance and possibly lead to turbocharger,
engine or power train related parts including
transmission, damage.
Also, do not remove the trunk carpet from the
vehicle for any reason. The carpet insulates the
vehicle interior from the heat of the muffler and
from the noise of the transmission.
EXTERIOR PARTS (spoiler, etc.)
Do not modify exterior parts.
The GT-R was developed using a special wind
tunnel to help make sure the vehicle is
aerodynamically balanced. Additionally, the wind
tunnel was used to help make sure cool air flows
to the brakes, radiator and other components.
Additions of non-genuine GT-R specific acces-
sory exterior parts can change the air flow over
and around the body. This can affect vehicle
balance and cooling of various systems.
For example, if the front bumper is modified,
there is a possibility that brake cooling perfor-
mance may be reduced due to the decrease of
the air flow to the brake system.
Use only GT-R special specification parts.
Front bumper
The shape of the bumper helps pull air into the
engine compartment through the front wheel
housing to cool the radiator and brakes. Instal-
ling an aftermarket bumper may affect the air
flow in the engine compartment and decrease
the brake and engine cooling performance. An
aftermarket bumper may also change vehicle
balance by reducing front down force.
Rear spoiler
Installing an aftermarket rear spoiler may change
the down force balance between front and rear
of the vehicle. This can affect the handling
characteristics of the vehicle and affect the
operation of the ABS and VDC systems.
NOTICE
Modifications to exterior parts may
affect engine and transmission cooling
performance which can increase the
temperature in the engine compart-
ment. This can affect the operation or
damage parts located in the engine
compartment.

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

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) .

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.

TACHOMETER
The tachometer indicates the engine speed in
revolutions per minute (rpm) . Do not rev the
engine into the red zone
*1.
NOTICE
When engine speed approaches the red
zone, shift to a higher gear or reduce
engine speed. Operating the engine in
the red zone may cause serious engine
damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant tem-
perature.
The engine coolant temperature is within the
normal range when the gauge needle points
within the zone
*1shown in the illustration.
The engine coolant temperature varies with the
outside air temperature and driving conditions.
NOTICE
If the gauge indicates engine coolant
temperature near the hot (H) end of the
normal range, reduce vehicle speed to
decrease temperature. If gauge is over
the normal range, stop the vehicle as
soon as safely possible. If the engine is
overheated, continued operation of the
vehicle may seriously damage the en-
gine. (

5-14Starting and driving
NOTE:
.If the engine is difficult to start, de-
press the accelerator pedal all the way
to the floor and hold it. Push the
ignition switch with the brake pedal
depressed to start cranking the engine.
After 5 or 6 seconds, stop cranking by
pushing the ignition switch to the OFF
position, and then release the accel-
erator pedal. Then perform steps 1 to 5
to start the engine. If the engine starts,
but fails to run, repeat this procedure.
. Starting and stopping the engine over a
short period of time may make the
vehicle more difficult to start. If this
occurs, wait for more than 3 minutes,
and then push the ignition switch again
to start the engine.
. To maintain high performance over a
long period of time, the engine speed is
limited to 5,000 rpm when the engine is
revved with the shift lever in the
&Nor
&Pposition, and to 4,000 rpm when the
engine oil or coolant temperature is
low or higher than normal.
. If the ignition switch is pushed before
the shift lever is moved to the
&Pposition, the ignition switch will not change to the OFF position. If this
occurs, the SHIFT
&Pwarning display
appears on the vehicle information
display. When stopping the engine, be
sure to move the shift lever to the
&Pposition and then push the ignition
switch. Failure to do so may result in
discharge of the battery. (
“Shift
“P” warning” page 2-42)
. If the shift lever was in the
&A↔&Mor&Rposition when the engine was stopped,
then be sure to move the shift lever to
the
&Pposition before starting the
engine the next time. If the engine is
started with the shift lever in the
&Nposition, then it may not be possible to
drive the vehicle even when the shift
lever is moved to the
&A↔&Mor&Rposition. If this occurs, the SHIFT&Pwarning appears on the vehicle infor-
mation display. (“Shift “P” warn-
ing” page 2-42)
CAUTION
If the engine was stopped soon when
the engine is hot, the cooling fan may
operate for approximately 2 minutes
after the engine was stopped to cool the components in the engine compart-
ment. When the cooling fan is operat-
ing, be sure that hands or other items
do not get caught in it.
