GTR-6GT-R Overview
certified technician must inspect the �fehicle and
determine that only the �brake pads need to �be
replaced. In this case, replacing all �brake pads
and disc rotors as a set is not necessary.
Note that the replacement of �brake pads and the
disc rotors as a set on all four wheels should �be
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
hea�fy 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 hea�fy force �being repeatedly
applied to the �brakes during high performance
dri�fing. 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
The GT-R exhaust system is designed to pro�fide
the maximum �fehicle performance and to
protect the �fehicle from high exhaust gas
temperatures.
If non-genuine GT-R exhaust system parts are
used it is possi�ble that the muffler or other
exhaust system parts will deform and causedamage to the under�body. Non-genuine GT-R
exhaust system parts can also affect �fehicle
performance and possi�bly lead to tur�bocharger,
engine or power train related parts including
transmission, damage.
Also, do not remo�fe the trunk carpet from the
�fehicle for any reason. The carpet insulates the
�fehicle interior from the heat of the muffler and
from the noise of the transmission.
TITANIUM MUFFLER AND TRUNK
CARPET (if so equipped)
The �fehicle is equipped with a la�bel under the
console lid
*1that pro�fides the �body to the
titanium muffler clearance specification (for
example rear �bumper to muffler tu�be clearance) .
Since the exhaust gas temperature of the high
performance engine reaches a high temperature
(1,8328F (1,0008C) or more) , the muffler may �be
deformed or lowered due to the heat and then
the under�body or peripheral parts may �be
damaged. Therefore, periodic inspections for
the clearance �between the muffler and the
peripheral parts are required. Your GT-R has

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 e�fceed the normal
range, the color of the meter on the multi
function display changes to red to warn the
driver�b 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�b When the color of
the meter display changes to red, perform cool
down driving�b 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�b
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�b
. Engine oil temperature is 2758F (1358C) or
higher:
If the engine oil temperature is higher than
2758F (1358C), the meter display changes
to red, ma�fimum engine speed is automati-
cally limited to 4,000 rpm, and the transmis-
sion automatically changes from the
&M
position to the&Aposition�b
. 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�b However, the
vehicle can continue to be driven until the
temperature reaches 2958F (1468C) �b If the
oil temperature e�fceeds 284 8F (1408 C)
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�b
Cool down
The information and specifications in this
section apply only when engaging in
performance driving.
Cool down the vehicle to help e�ftend the life of the vehicle if coolant temperatures are e�ftremely
high�b 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�b
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 ma�fimize vehicle performance, the fuel tank is
located as low as possible to lower the vehicle
center of gravity�b The tank is also divided into
two parts�b 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�b
The fuel tank pressure is higher when the vehicle
is hot, especially if the tank is more than half full�b
If the cap is opened when the vehicle is hot, it
may cause fuel spray and there may be a hissing
noise�b Open the cap slowly, releasing the
pressure from the tank gradually�b Also, if the

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 tan�f is
located as low as possi�ble to lower the vehicle
center of gravity. The tan�f is also divided into
two parts. This fuel tan�f design causes higher
pressures inside the tan�f than other vehicles so
fuel spillage is possi�ble �by trying to top off the
fuel tan�f after automatic shutoff.
The fuel tan�f pressure is higher when the vehicle
is hot, especially if the tan�f 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 tan�f gradually. Also, if the
vehicle is refueled when the vehicle is hot, the
fuel pump may automatically shut off �before the
tan�f 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 (08C)) 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
3,281 ft (1,000 m) 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

2. Check that the pa\fking b\fake is engaged.
3. Check that the shift leve\f is in the
&Po\f&N
position. (&Pis \fecommended.)
4. Fi\fmly dep\fess the b\fake pedal. Without dep\fessing the accele\fato\f pedal, push the
ignition switch once to sta\ft the engine.
5. To stop the engine, move the shift leve\f to the
&Pposition, and push the ignition switch
to the OFF position. NOTE:
.
Care should be taken to avoid situa-
tions that can lead to potential battery
discharge and potential no-start condi-
tions such as:
a. Installation or extended use of elec-
tronic accessories that consume
battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
b. Vehicle is not driven regularly and/
or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
. 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
&P
position, 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
&P
position and then push the ignition
switch. Failure to do so may result in
discharge of the battery. (

.
Failure to follow the warnings and
instruction for the use of this fea-
ture may cause a loss of vehicle
control or a collision which may lead
to serious personal injury or death:
. Make sure to drive carefully within
legal limits.
. Only use this function when you can
guarantee that it is safe to do so,
based on the surrounding traffic
conditions.
. Do not use this function on slippery
or wet roads. This may cause loss of
vehicle control and could result in
an accident.
. The R mode start function has been
developed not only for controlling the engine, transmission and VDC
system, but also the settings of the
