VEHICLE DYNAMIC CONTROL (VDC)
OFF MODEMake sure VDC is on before driving the vehicle.
The VDC OFF mode should only be used to help
free a vehicle stuck in mud or snow by
temporarily stopping VDC operation and keep-
ing torque on wheels.SUMMER TIRESThe GT-R summer tires are made from a
specially formulated rubber to maximize the
vehicle’s performance capabilities. Performance
of summer tires is substantially reduced when
temperatures are less than 328F(0 8C) so you
must drive carefully. NISSAN recommends the
use of winter or all-season tires on all four
wheels if you plan to operate your vehicle in
snowy or icy conditions when temperatures are
less than 32 8F(0 8C) .
WARNING
Never use summer tires when the
temperature is below 48 F( 20 8C) to
prevent permanent tread deformation
which may cause tire damage or tire
failure. This may cause a loss of vehicle
control which can result in serious
personal injury or death.
ALL-SEASON TIRESDo not exceed the speed rating of the tire that is
installed on the vehicle.
The body of the GT-R has been manufactured
on special fixtures utilizing a hybrid structure
with aluminum die cast parts for the frame work.
Special skills, information and equipment are
required to correctly repair the body. Contact a
GT-R certified NISSAN dealer if the vehicle is
damaged, such as in a collision, and they will
recommend an appropriate body shop.
Only certified body shops using CELETTE
®
advanced collision repair equipment are ap-
proved by NISSAN for repairing structural body
damage. Contact a GT-R certified NISSAN
dealer or NISSAN Consumer Affairs for a
referral or list of certified body shops.

TRANSMISSION OPERATION CHARACTERISTICS
MechanismOperation characteristics
Base Manual transmission
.
When the temperature of the transmission is high, the decreased friction from idling and driving at low speeds can cause rattling, shaking
and jarring noises. When the temperature of the transmission decreases, the noise will lessen.
.
Clattering noises may be heard while 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.
.
Never depress the brake and accelerator pedals at the same time. Depressing the brake and accelerator pedals at the same time could
cause:—
The engine to stall
—
The clutch to overheat
—
Transmission damage
.
To prevent stalling or transmission damage, start in first gear. The
&Mposition second gear can be used to start moving the vehicle only
when reduced torque is necessary on snowy roads or extremely slippery surfaces.
.
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 fluid 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 fluid returns to normal operating temperatures.
.
When the transmission fluid 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.
.
Quick 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.
Gear clearances 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.

desired:Set the figure at 5,200 RPM. The green
indicator starts flashing from approximately
4,700 RPM and illuminates at 5,200 RPM.When breaking-in the vehicle:To help avoid high engine speeds during break-
in, set the upshift indicator to less than 3,500
RPM. The green indicator starts flashing ap-
proximately 500 RPM before the set figure and
illuminates from the set figure. (

SCHEDULE” page 5-32)
NOTE:. There may be a slight difference be-
tween the timing of the upshift indica-
tor illumination and the tachometer
indication.
. When the battery terminal is discon-
nected, the set memory will be erased
and the mode returns to the default.

DRIVING TIPSAfter starting the engine, fully depress the foot
brake pedal and push the shift lever button
before shifting the shift lever from the
&Pposition
to the
&R,&N,or
&A↔&M
position. Be sure the
vehicle is fully stopped before attempting to shift
the shift lever.
The transmission is designed so that the foot
brake pedal must be depressed before shifting
from
&Pto any other position.
The shift lever cannot be moved out of the
&P
position and into any other position with the
ignition switch other in the LOCK, OFF or ACC
position.When accelerating from a stopKeep the foot brake pedal depressed and push
the shift lever button to shift into a driving gear
as following:
. To drive forward, move the shift lever to the
&A↔&M
position.
. To back up, move the shift lever to the
&R
position.
Starting on level ground:1. Check the shift lever position indicator on
the instrument panel to confirm that the
driving gear is selected.
2. Release the parking brake.
3. Release the foot brake pedal, then gradually depress the accelerator pedal to start the
vehicle in motion.Starting on an uphill:1. Check the shift lever position indicator onthe instrument panel to confirm that the
driving gear is selected.NOTE:When starting or driving on a steep uphill
grade, shift to the
&M
position and operate
the paddle shifter to shift down to 1st gear
as a manual transmission vehicle.
2. With the parking brake applied, slowly release the foot brake pedal.
3. Slowly depress the accelerator pedal and feel the vehicle starting motion with the
parking brake applied.
4. Release the parking brake and gradually depress the accelerator pedal to start the
vehicle in motion.
NOTICE
To prevent stalling or transmission
damage, start in 1st gear. The
&M
position 2nd gear can be used to start
moving the vehicle only when reduced
torque is necessary on snowy roads or
extremely slippery surfaces.NOTE:The hill start assist function operates when
the vehicle is accelerating from a stop on
an uphill. (

Normal driving:Drive with the shift lever in the
&Aposition.
The appropriate gear will be automatically
shifted according to the position of the accel-
erator pedal, the driving speed and driving
conditions.
Passing or hill climbing:.
&Aposition:
Fully depress the accelerator pedal to the floor.
This shifts the transmission down into a lower
gear depending on the vehicle speed.
NOTE:When starting or driving on a steep uphill
grade, shift to the
&M
position and operate
the paddle shifter to shift down to 1st gear
as a manual transmission vehicle.
.
&M
position:
Use the paddle shifter to shift down, then
depress the accelerator pedal depending on
the vehicle speed.
Driving on a downhill:.
&Aposition:
The system shifts down according to the degree
of downhills to increase the effectiveness of the
engine brake. .
&M
position:
When driving on a long slope, selecting the
&M
position and 4th or 3rd gear will provide gentle
engine braking.
When driving on a steep downhill, selecting the&M
position and 2nd or 1st gear will provide
powerful engine braking.
WARNING
. When the shift lever is in the
&A
position, the adaptive shift control
system will stay in a low gear in
order to maintain the effectiveness
of the engine brake. However if the
vehicle is traveling too fast depend-
ing on the degree of the slope, you
should shift to the
&M
position and
use the paddle shifter to shift down.
If you continue to use only the foot
brake, a high load will be applied to
the brake, which may overheat,
reducing its effectiveness. Be sure
to use the engine brake together
with the foot brake. (
“Adaptive
shift control” page 5-17)
. The adaptive shift control system
may not operate when the transmis-
sion is not warm immediately after the start of driving, or when the oil
temperature is high. In this case,
depending on the degree of the
slope, you should shift to the
&M
position and select a lower gear.
. Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
When stopping the vehicleLeave the shift lever in the
&A↔&Mor&Rposition
and firmly depress the foot brake pedal.
If the vehicle will be stopped for a long period of
time, apply the parking brake and move the shift
lever to the
&Por
&Nposition as necessary.WARNING
. Do not race the engine while the
vehicle is stopped. Doing so may
accelerate the vehicle suddenly and
cause an accident when shifting to a
driving gear.
. While the engine is running, the
propeller shaft that transmits torque
from the engine to the transmission
is turning at all times. Crawling or
reaching under the vehicle while the
engine is running may result in

&Aor
&M.
&Aposition:Set up modeFeatures
.
In addition to the normal mode functions, this mode allows you to achieve higher
engine speed, greater powertrain torque and engine braking.
Normal
(light is off)
.
For everyday driving an appropriate gear position is automatically selected for optimal
fuel mileage.
.
This mode controls powertrain torque on snowy roads and slippery surfaces making
starting and driving easier.
&M
position:Set up mode Features
.
This mode allows you to shift gears more quickly than the normal mode.
.
This mode will not allow the transmission to automatically upshift even when the
engine speed reaches the red zone. Do not rev the engine into the red zone.
.
When the engine speed is low, downshift will be automatically carried out to ensure
driving performance.
Normal
(light is off)
.
Upshift will be automatically carried out just before the red zone to prevent excessive
engine speed.
.
When the engine speed is low, downshift will be automatically carried out to ensure
driving performance.
NOTE:The SNOW mode cannot be selected with the transmission in the
&M
position.
NOTICE
. When the engine speed approaches
the red zone, shift to a higher gear
or reduce the engine speed. Operat-
ing the engine in the red zone may
cause serious engine damage.
. Quick shifting in the R mode with
the transmission in the
&M
position
is available when the engine speed
is high. However, the transmission
may shift more slowly when the
engine speed is low. This does not
indicate that there is a malfunction.

TIGHT CORNER BRAKING PHE-
NOMENONWhen driving on dry pavement in AWD mode, or
immediately after starting the engine in cold
conditions, when the steering wheel is turned all
the way, the vehicle may behave as if the brakes
had been applied. 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. If this phenomenon
occurs, more force will be required to operate
the steering wheel.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.
. If excessive operation continues when
a wheel has come off the road or at
other times when the operation causes a large difference in speed between the
front and rear wheels (the wheels are
spinning) , the oil temperature in the
drive system parts will increase.
In this case, to protect the drive system
parts, the AWD warning light blinks
rapidly and the system switches to
RWD mode or low AWD mode. Keep
the vehicle stopped and idling for a
short time. When the warning light
stops blinking, the vehicle returns from
RWD mode to normal driving mode.
. If you feel an unusual vibration in the
vehicle, even if the warning lights are
not illuminated, have the vehicle in-
spected by a GT-R certified NISSAN
dealer.
TIRESThis 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 CHARACTERISTICSThe AWD system automatically distributes the
optimal torque to the front and rear wheels. This
provides both the superior turning performance
of a front wheel drive vehicle and the traction of
a AWD vehicle.
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.

This vehicle is equipped with a 1.5-way me-
chanical Limited Slip Differential (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 this
vehicle is characterized by its asymme-
trical LSD effects when the accelerator
pedal is ON and when it is OFF. This
allows the appropriate amount of tor-
que for the driving environment to be
transmitted to the road surface.5-36

. If engine related parts such as
muffler are not standard equipment
or are extremely deteriorated, the
indicator or
indicator or
both indicator lights may illuminate.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars and bushings are
not NISSAN approved or are extre-
mely deteriorated the VDC system
may not operate properly. This could
adversely affect vehicle handling
performance, and the
indicator
or
indicator or both indicator
lights may illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extre-
mely deteriorated, the
indicator
or
indicator or both indicator
lights may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the
in-
dicator or
indicator or both indicator lights may illuminate. Do
not drive on these types of roads.
. When driving on unstable surfaces
such as a turntable, ferry, elevator
or ramp, the
indicator or
indicator or both indicator lights
may illuminate. This does not indi-
cate that there is a malfunction.
Restart the engine after driving onto
a stable surface.
. If wheels or tires other than those
recommended are used, the VDC
system may not operate properly
and the
indicator or
in-
dicator or both indicator lights may
illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
NOTE:.Make sure VDC is on before driving the
vehicle. The VDC OFF mode is an
emergency mode to help free a vehicle
stuck in mud or snow by temporarily
stopping VDC operation and keeping
torque on the wheels.
. 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.
. When the VDC system is turned OFF,
all VDC functions (including traction
control) , except for the ABS functions,
are deactivated.
