to detect
engine booming noise. The system then
automatically generates a noise cancel-
ling sound through the speakers
and
woofer
to reduce engine booming
noise.
The front and rear microphones
are
located inside of the roof.
The front speakers are located on the
doors and the woofer is located in
between the rear seats.
ACTIVE SOUND ENHANCEMENTThe active sound enhancement gener-
ates sounds according to engine speed
and driving modes selected by the Vehicle
Dynamic Control (VDC) system, transmis-
sion and suspension setup switches
through the speakers
and woofer
to enhance the quality of the engine
sound.
In addition, if the gear is shifted or the
accelerator pedal is quickly operated
when the transmission setup switch is in
R mode and the engine warmed up, a
sound effect is output to enhance the
sense of sportiness. (

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.

The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip
based on vehicle speed (traction con-
trol function).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle
in the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the meter flashes so note the following:
.
The road may be slippery or the
system may determine some action
is required to help keep the vehicle on
the steered path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
. The VDC mode can be changed using
the VDC setup switch. (

transmission and suspension setup
switches” page 5-25)

Dynamic Control (VDC) off indicator light”

If a malfunction occurs in the system, the
VDC warning light
illuminates in the
meter. The VDC system automatically
turns off.
The VDC setup switch is used to turn off
the VDC system. The VDC off indicator
illuminates to indicate the VDC sys-
tem is off.

NOTE:
Do not keep the starter motor en-
gaged for more than 10 seconds. If
the engine does not start right away,
push the ignition switch to the OFF
position and wait 10 seconds before
trying again.

pushing.
NOTICE
Your NISSAN cannot be push-started
or tow-started. Attempting to do so
may cause transmission damage.
WARNING
.
Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, never remove the radia-
tor filler cap and the coolant
reservoir cap while the engine is
still hot. When the cap is removed,
pressurized hot water will spurt
out, possibly causing serious in-
jury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect unusual noise, etc., take the
following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the
position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the temperature
control to maximum hot and fan
PUSH STARTING IF YOUR VEHICLE OVERHEATS

If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device
designed specifically for vehicle recovery.
Always follow the manufacturer’s instruc-
tions for the recovery device.Rocking a stuck vehicleIf your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control(VDC) system and select SAVE mode
with the transmission setup switch.
(
“VDC, transmission and suspen-
sion setup switches” page 5-25)
2. Make sure the area in front and behind the vehicle is clear of obstruc-
tions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.
.
Shift back and forth between theand
and

position, 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
position, the ignition switch
will not change to the OFF position.
If this occurs, the SHIFT
warning
display appears on the vehicle in-
formation display. When stopping
the engine, be sure to move the shift
lever to the
position and then
push the ignition switch. Failure to
do so may result in discharge of the
battery. (“Shift “P” warning”
page 2-46)
. If the shift lever was in the
position when the engine was
stopped, then be sure to move the
shift lever to the
position before
starting the engine the next time. If the engine is started with the shift
lever in the
position, then it may
not be possible to drive the vehicle
even when the shift lever is moved
to the
position. If this
occurs, the SHIFTwarning appears
on the vehicle information display.

“Shift “P” warning” page 2-46)
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 compartment. When the
cooling fan is operating, be sure that
hands or other items do not get
caught in it.
DUAL CLUTCH TRANSMISSIONThe GT-R dual clutch transmission is a
newly-developed system that uses an
electronically controlled multiple-disc
wet clutch attached to the highly efficient

transmission vehicle.
The GT-R dual clutch transmission was
developed specifically to maximize vehi-
cle performance and driving enjoyment.
The GT-R transmission components were
designed using different engineering
standards than typical passenger car
transmissions. Because of this, the GT-R
has different operating characteristics,
and various rattle noises may be heard
during some driving conditions because

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

, 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.
