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.This function enables the driver to start accel-
eration from a stop by selecting R mode with the
VDC and transmission setup switch. The engine
output will be maintained at approximately 4,000
rpm. When using the R mode or the R mode
start function, always use proper seating posi-
tion and follow the safety instructions in Section
1 of this manual.
WARNING
.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
suspension and tires. Therefore, any
modification of the vehicle may
disrupt the vehicle’s balance. This
will not only reduce the optimum
performance of the vehicle but may
also cause damage to powertrain
components, including the trans-
mission.
NOTICE
.
When the temperature of the engine
coolant and transmission oil is high
or low, the function cannot be used.
The temperature range in which the
R mode start function can be used:
— Engine coolant: 1408F - 2128F
(608C - 1008C)
— Transmission oil: 1408F - 2668F (608C - 1308C)
. If the R mode start function is used
4 times consecutively, the function
may be disabled and cannot be
turned on to protect the vehicle
system. While the function is dis-

ing the cancel switch or by depressing
the brake pedal, the system changes to
standby status.
. If you depress the brake pedal while
pushing the RESUME/ACCELERATE or
SET/COAST switch and reset at the
cruising speed, the cruise control will
be deactivated. Turn the MAIN switch
off once and then turn it on again.
Under the following conditions, cruise control
will be automatically canceled.
. Vehicle speed drops to below approximately
19 MPH (30 km/h) .
. Vehicle speed drops to more than approxi-
mately 8 MPH (13 km/h) below the set
vehicle speed.
. The shift lever is moved to a position other
than
&A↔&M.
. VDC operates.
. A tire is spinning.
. There is a malfunction in the cruise control
system.
WARNING
.Never rely solely on the hill start
assist system to prevent the vehicle
from moving backward on a hill.
Always drive carefully and atten-
tively. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Be especially careful
when stopped on a hill on frozen
or muddy roads. Failure to prevent
the vehicle from rolling backwards
may result in a loss of control of the
vehicle and possible serious injury
or death.
. The hill start assist system is not
designed to hold the vehicle at a
standstill on a hill. Depress the
brake pedal when the vehicle is
stopped on a steep hill. Failure to
do so may cause the vehicle to roll
backwards and may result in a
collision or serious personal injury.
. The hill start assist may not prevent
the vehicle from rolling backwards
on a hill under all load or road
conditions. Always be prepared to
depress the brake pedal to prevent the vehicle from rolling backwards.
Failure to do so may result in a
collision or serious personal injury.
NOTICE
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.
The hill start assist system automatically keeps
the brakes applied to help prevent the vehicle
from rolling backwards in the time it takes the
driver to release the brake pedal and apply the
accelerator when the vehicle is stopped on a hill.
Hill start assist will operate automatically under
the following conditions:
. The shift lever is moved to a forward or
reverse position.
. The vehicle is stopped completely on a hill
by applying the brake.
The maximum holding time is 2 seconds. After 2

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..Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
. Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
. Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
. Select a gear range suitable to road condi-
tions.
. Avoid unnecessary engine idling.
. Keep your engine tuned up.
. Follow the recommended periodic mainte-
nance schedule.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
. Air conditioner operation lowers fuel econ-
omy. Use the air conditioner only when
necessary.
. When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag. .
Use the recommended viscosity engine oil.

AWD WARNING LIGHT
The AWD warning light is located in the meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position. It
turns off soon after the engine is started.
If any malfunction occurs in the AWD systemwhile the engine is running, the warning light will
come on.
The warning light may blink rapidly (about twice
per second) while trying to free a stuck vehicle
due to high AWD clutch temperature. The
driving mode may change to two-wheel drive.
If the warning light blinks rapidly during opera-
tion, stop the vehicle with the engine idling in a
safe place immediately. Then if the light goes off
after a while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning light
blink slowly (about once per two seconds) . Pull
off the road in a safe area, and idle the engine.
Check that all tire sizes are the same, tire
pressure is correct and tires are not worn and
winter tires are not installed on the front or rear
wheels only.
If the warning light is blinking after the above
operation, have your vehicle checked by a GT-R
certified NISSAN dealer as soon as possible.
If non-genuine GT-R tires are used, the warning
light may illuminate. (
“GT-R special speci-
fication parts” page GTR-3)
WARNING
. Do not attempt to raise two wheels
off the ground and shift the trans-
mission to any drive or reverse
position with the engine running.
Doing so may result in drivetrain
damage or unexpected vehicle
movement which could result in
serious vehicle damage or personal
injury.
. Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing) or similar equip-
ment even if the other two wheels
are raised off the ground. Make sure
that you inform the test facility
personnel that your vehicle is
equipped with AWD before it is
placed on a dynamometer. Using
the wrong test equipment may re-
sult in drivetrain damage or unex-
pected vehicle movement which
could result in serious vehicle da-
mage or personal injury.

ALL-WHEEL DRIVE (AWD)

5-42Starting and driving
NOTICE
.If the warning light comes on while
driving there may be a malfunction
in the AWD system. Reduce the
vehicle speed and have your vehicle
checked by a GT-R certified NISSAN
dealer as soon as possible.
. If the warning light remains on after
the above operation, have your
vehicle checked by a GT-R certified
NISSAN dealer as soon as possible.
. The powertrain may be damaged if
you continue driving with the warn-
ing light blinking.
. Do not spin the rear wheels while
driving. Spinning the rear wheels
may increase the temperatures of
the AWD clutch system and damage
the system. Adjust the accelerator
pedal position to stop wheel spin.
TIGHT CORNER BRAKING PHE-
NOMENON
If the steering wheel is turned more than half a
turn when the vehicle is started when it is cold, it
may be harder to move the vehicle forward and
backward. This phenomenon is known as the
“tight corner braking phenomenon”.
This phenomenon is unique to AWD vehicles,
and occurs due to a difference in speeds
between the front and rear wheels while the
vehicle is turning. This does not indicate that
there is a malfunction.
NOTE:
If the tight corner braking phenomenon
occurs, a slipping sound may be heard
from the tires, or a squeaking sound may
be heard from the drive system.
Reducing tight corner braking phe-
nomenon
The tight corner braking phenomenon can be
temporarily reduced.
Push the transmission setup switch down for
approximately 4 seconds while the engine is
running.
.The SAVE mode indicator will blink once
and will then turn off.
. If the SAVE mode is already selected, the
SAVE mode indicator will blink once and
then illuminate again. (
“VDC, transmis-
sion and suspension setup switches” page
5-24)

After performing the above, the vehicle switches
from the AWD mode to 2WD mode only if both
of the following conditions are met:
.Vehicle speed is less than approximately 6
MPH (10 km/h)
*AAND
. The steering wheel is turned more than 1/2
turn
*B.
If the above driving conditions are not met,
the vehicle will not switch to the 2WD
mode to temporarily reduce the braking
phenomenon even if the transmission
setup switch is operated.
To stop reducing the phenomenon, push the
transmission setup switch down for approxi- mately 4 seconds again. The driving mode will
switch to the normal AWD mode.
Reduction of the tight corner braking phenom-
enon will be cancelled when:
.
the R mode is selected with the transmission
setup switch
. the SAVE mode is selected with the
transmission setup switch and the OFF
mode is selected with the VDC setup switch
. the ignition switch is pushed to the "OFF"
position
. the R mode start function is used
WARNING
Do not reduce the tight corner braking
phenomenon when driving on a road
surface that is slippery or covered in
snow, because the driving mode will
switch to 2WD. This may cause tire
slipping and may cause a loss of control
and result in a collision, personal injury
or death.
TIRES
This vehicle is equipped with special tires. When
changing the tires, install the designated special
tires. Replacing tires as a set of four with new
ones is recommended. However, if a tire is
punctured or damaged, it may be possible to
replace only the damaged tire. Determining
whether one tire or a complete set of tires
should be replaced is based on a number of
factors including tire wear and condition. Con-
tact your GT-R certified NISSAN dealer. They
can recommend if an individual tire or a
complete set should be replaced.
NOTICE
If tires other than the designated tires,
tires with large differences in wear or
tires of different sizes are installed, the
AWD performance will be degraded and
the drive mechanism may be damaged.
AWD SYSTEM CHARACTERISTICS
The AWD system automatically distributes the
optimal torque to the front and rear wheels. This
provides both the superior turning performance
of a rear wheel drive vehicle and the traction of a
AWD vehicle.
Starting and driving5-43

5-44Starting and driving
Electronic control continuously distributes tor-
que to the front and rear wheels in the range
from 0:100 (rear-wheel drive mode) to 50:50
(all-wheel drive mode) to match the driving
conditions and road conditions. This allows the
engine output (torque) to be effectively trans-
mitted to the road surface.The rear final drive of this vehicle is equipped
with a 1.5-way mechanical Limited Slip Differ-
ential (LSD) .
WARNING
Sudden operation of the accelerator
pedal can result in fishtailing or side-
slip, possibly causing an accident. Use
particular caution when driving in rainy
weather or on slippery roads.
NOTICE
Use the designated differential gear oil.
If any oil other than the designated oil
is used, the LSD may not operate
correctly, and noise and vibration may
occur, possibly resulting in a malfunc-
tion.
NOTE:
. If the vehicle accelerates from a stop
with the steering wheel turned in cold
temperatures, the inner wheel tire may
slip and some noise or vibration may
be heard. This phenomenon is unique
to vehicles equipped with the LSD. This does not indicate that there is a mal-
function.
. The LSD controls the speed difference
between the left and right wheels, and
optimally allocates torque to the
wheels.
. The 1.5-way mechanical LSD in the rear
final drive of this vehicle is character-
ized by its asymmetrical LSD effects
when the accelerator pedal is ON and
when it is OFF. This allows the appro-
priate amount of torque for the driving
environment to be transmitted to the
road surface.

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance
from the vehicle in front of you.
Ultimately, the driver is responsible
for safety.
. Tire type and condition may also
affect braking effectiveness. When
replacing tires, install the specified
size of tires on all four wheels.
The Anti-lock Braking System (ABS) controls the brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forwardor reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This does not indicate that there is
a malfunction. If the computer senses a mal-
function, it switches the ABS off and illuminates
the ABS warning light on the instrument panel.
The brake system then operates normally, but
without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a GT-R certified NISSAN dealer.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.
BRAKE ASSIST

5-50Starting and driving
shock absorbers, struts, springs,
stabilizer bars, bushings and
wheels are not NISSAN approved
or are extremely deteriorated, the
VDC system may not operate prop-
erly. This could adversely affect
vehicle handling performance, and
the VDC warning light
may
illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are
not standard equipment or are ex-
tremely deteriorated, the VDC warn-
ing light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the VDC warn-
ing light
may illuminate. Do not
drive on these types of roads.
. When driving on an unstable sur-
face such as a turntable, ferry, elevator or ramp, the VDC warning
light
may illuminate. This is not
a malfunction. Restart the engine
after driving onto a stable surface.
. If wheels or tires other than the
those recommended are used, the
VDC system may not operate prop-
erly and the VDC warning light
may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
NOTE:
. 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
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 2013 Warranty Information Booklet for
important related information and warranty
coverage exclusions. See also section 2 (page
2-29) and section 5 (page 5-49) of this Owner’s
Manual, “Transmission Clutch Temperature
High” and “Vehicle Dynamic Control (VDC)
System” for important additional related informa-
tion.
.Except for the emergency cases above,
any issues related to driving stability
(e.g., steering maneuvers and maneu-
vers during acceleration and decelera-
tion) and any damages to drivetrain
components (e.g., transfer, clutch, a
sort of gear, transaxle case) will not
be covered by warranty if there is a
record in the Vehicle Status Data
Recorder (VSDR) that the vehicle was
driven with VDC off.
. When attempting to free the vehicle
from mud or fresh snow, the VDC will
detect the tire slipping, and the engine
speed may not increase even when the
accelerator pedal is depressed. To raise
the engine speed, use the VDC set up
switch to turn the VDC system OFF and
select SAVE mode with the transmis-
sion switch. (
“VDC, transmission
and suspension setup switches” page 5-24)
. When the VDC system is turned OFF,
all VDC functions (including traction
control) , except for the ABS functions,
are deactivated.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole or use the Intelligent Key system.
ANTI-FREEZE
In the winter when it is anticipated that the
outside temperature will drop below 328F(0 8C) ,
check antifreeze to assure proper winter protec-
tion. (
“Engine cooling system” page 8-10)
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery should
be checked regularly. (
“Battery” page 8-
17)
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, contact a GT-R certified
NISSAN dealer.
