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.
CAUTION
. Because the vehicle includes a
dual clutch transmission that
automatically controls the clutch
and shifting operation of the
manual transmission, whenever
the shift lever is in a position
other than
or
, the vehicle will
begin to move slowly, in the same
way as when the clutch in a
manual transmission vehicle is
partially engaged. Keep the brake
pedal firmly depressed when the vehicle is stopped. In some cir-
cumstances the vehicle may not
start moving on its own, however
this does not indicate that there
is a malfunction.
NOTICE
.
To avoid possible damage to your
vehicle; when stopping the vehi-
cle on an uphill grade, do not hold
the vehicle in place by depressing
the accelerator pedal. Doing so
may cause the clutch to overheat
and result in transmission da-
mage. Use the brakes to prevent
the vehicle from moving.
. The GT-R dual clutch transmis-
sion is provided with a dry sump
lubrication system that improves
efficiency and ensures reliability
under high g-force conditions.
When oil viscosity is high at low
temperatures, it takes longer for
all components to be sufficiently
lubricated. Thus, when the trans-
mission temperature is low (ap-
proximately 104°F (40°C), do not
accelerate rapidly or run the en-
gine faster than 4,000 rpm.

position. Be sure to depress the
brake pedal.
NOTICE
. Be sure to observe the following
precautions. Failure to do so may
result in shift lever malfunction.
— Do not spill water, beverages
or other liquids on the shift
lever.
— Do not allow sand or similar substances to contact the
shift lever.
. Develop the habit of performing
the operations marked with “
”
without pressing the button. If
the button is pressed at these
times, there is the possibility that
the lever could accidentally enter
the
or
positions.
. When the vehicle is hot, the area
around the shift lever may be hot
or may produce an unusual
sound, however this does not
indicate that there is a malfunc-
tion.
. Avoid depressing the brake and
accelerator pedals at the same
time. Depressing both pedals at
the same time could cause the
clutch to overheat and accelerate deterioration.
NOTE:
. When moving the shift lever out of
the
position, it may not be possi-
ble to move the shift lever if the
button is pressed before the brake
pedal is depressed. Press the button
only after depressing the brake
pedal.
. Do not place coins or other small
objects in the area around the shift
lever. These objects may get stuck in
the shift gate and prevent the shift
lever from moving into a position.
Sometimes, you may not be able to
retrieve these objects.
. Immediately after a cold start, while
the transmission system check dis-
play (“T/M SYSTEM CHECK IN PRO-
CESS”) appears on the vehicle
information display, the shift lever
cannot be moved out of the
position. This is because a check of
the transmission system is in pro-
gress. This does not indicate that
there is a malfunction. Move the
shift lever after the message on the
vehicle information display turns off.
. The shift lever knob and console-

mounted shift indicator have a gen-
uine leather finish that requires
proper care and maintenance.

Shift lock releaseIf the battery charge is low or discharged,
the shift lever may not be moved from the
position even with the brake pedal
depressed and the shift lever button
pushed.
To move the shift lever, perform the
following procedure.
1. Push the ignition switch to the OFF or LOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover using a suitable tool wrapped with a cloth.
4. Push down the shift lock as illustrated. 5. Push the shift lever button and move
the shift lever to the
position while
holding down the shift lock.
Push the ignition switch to the ON posi-
tion to unlock the steering wheel. Now
the vehicle may be moved to the desired
location.
If the battery is discharged completely,
the steering wheel cannot be unlocked.
Do not move the vehicle with the steering
wheel locked.
NOTICE
If the shift lever cannot be moved
out of the
position after perform-
ing the shift lock release procedure,
it is recommended you immediately
have the vehicle inspected by a GT-R
certified NISSAN dealer.
Adaptive shift controlThe adaptive shift control system auto-
matically operates when the transmission
is in the
position and selects an
appropriate gear depending on the road
conditions such as uphill, downhill or
curving roads.Starting and driving

.To drive forward, move the shift lever
to the
position.
Starting on level ground or an uphill:
1. Check the shift lever position indicator on the meter to confirm that the
driving gear is selected.
2. Release the parking brake.
3. Release the foot brake pedal gradu- ally, then slowly depress the accelera-
tor pedal to start the vehicle in
motion.
(“R mode start function” page 5-33)
NOTE:
. To prevent the clutch from over-
heating when the parking brake is
applied, engine output is limited
when the accelerator pedal is de-
pressed. In particular, the vehicle
may not start smoothly when the
accelerator pedal is depressed with
the parking brake applied on an
uphill grade. To enable smooth
starting, release the parking brake
before moving the vehicle.
. The hill start assist system operates
when the vehicle is accelerating
from a stop on an uphill. (
“Hill
Start Assist System” page 5-39)
When driving the vehicle
WARNING
Do not move the shift lever to theposition while driving. Doing so may
result in an accident due to loss of
engine braking. It may also damage
the transmission.
Normal driving:
Drive with the shift lever in the
position.
The appropriate gear will be automati-
cally shifted according to the position of
the accelerator pedal, the driving speed
and driving conditions.
Passing:

position. This automatically shifts the
transmission into a lower gear and
maintains this position depending on
the gradient of the hill.
. The system may down shift according
to the accelerator pedal position and
the vehicle speed.
. If the transmission is frequently chan-
ging gears while driving, switch to theposition and select the appropriate
gear for the driving conditions.
Driving on a downhill:
.position and 4th or 3rd gear will
provide gentle engine braking.
When driving on a steep downhill, select-
ing the
position and 2nd or 1st gear will
provide powerful engine braking.

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: 140°F - 212°F
(60°C - 100°C)
— Transmission oil: 140°F - 266°F (60°C - 130°C)
. 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 disabled, the warning
light illuminates. When the warn-
ing light illuminates, perform cool
down driving. (
“Cool down”
page GTR-14) When the warning
light turns off, the function can be
used again.
. The performance of start may
vary depending on the amount
of wheel spin ,or increase and
decrease of the engine output in
response to the outside tempera-
ture. (This vehicle was set up
according to the road surface
conditions of the straight sec-
tions of the Sendai Highland Ra-
ceway course in Japan at 59°F
(15°C).)
. For safety reasons, VDC control
may activate automatically when
driving on a slippery road surface,
such as a wet road, in order to
apply the brakes or limit the
engine output.
. Frequent use of the R mode start
function increases the load on
the powertrain related parts such
as the clutch and transmission
compared to normal driving. In
particular, the clutch will wear out

R MODE START FUNCTION

Do not use the cruise control when
driving under the following condi-
tions. Doing so could cause a loss of
vehicle control and result in an acci-
dent.
.When it is not possible to keep
the vehicle at a set speed.
. In heavy traffic or in traffic that
varies in speed.
. On winding or hilly roads.
. On slippery roads (rain, snow, ice,
etc.).
. In very windy areas.
NOTE:
. When the SAVE mode is selected
with the transmission setup switch,
the acceleration and deceleration
can be controlled smoothly. When
the SAVE mode is selected, the
maximum setting speed is lower
than the one in the normal mode. When the vehicle approaches a gen-
tle uphill, there may be a slight delay
as the vehicle returns to the preset
speed. However, the vehicle will
gradually accelerate and return to
the preset speed.
PRECAUTIONS ON CRUISE CON-
TROL.
If the cruise control system malfunc-
tions, it will cancel automatically. The
SET indicator will blink and the cruise
control system warning will appear to
warn the driver. (

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 seconds the vehicle will begin to
roll back and hill start assist will stop operating completely.
Hill start assist will not operate when the
shift lever is moved to the
or
position
or on a flat and level road.
NOTE:
This system does not function when the

TIGHT CORNER BRAKING PHE-
NOMENONIf 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 malfunc-
tion.
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
phenomenonThe tight corner braking phenomenon
can be reduced if the following three
conditions are met:
.Transmission setup switch is set to
Normal mode.
. Vehicle speed is low (less than ap-
proximately 6 MPH (10 km/h)). .
The steering wheel is turned more
than 1/2 turn.
TIRESThis vehicle is equipped with special tires.
When changing the tires, install the de-
signated special tires. Replacing tires as a
set of four with new ones is recom-
mended. 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. Contact 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 mechan-
ism may be damaged.
AWD SYSTEM CHARACTERISTICSThe AWD system automatically distri-
butes 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.
Electronic control continuously distri-
butes torque 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 transmitted to
the road surface.
