BRAKE SYSTEM INFORMATIONGUID-B79B98DE-81A3-42BD-B90B-1C1E8555F545
Cracks on brake padGUID-BC1FEDEC-F463-4D51-B3F4-6962DD94A963The friction material of the GT-R disc brake pad
is bonded to the pad backing plate more
strongly than conventional brake pads to with-
stand the high brake temperatures. The friction
material and backing plate expand due to heat at
different rates. Some cracks may be on the
surface of the friction material due to the
differences in expansion rates and the strong
bond between the friction material and backing
plate. The cracks do not indicate the brake pads
need to be replaced. However, depending on
the condition of the cracks, the pads may need
to be replaced. It is recommended you contact a
GT-R certified NISSAN dealer.

Cracks on the disc rotorsGUID-52D20B8E-82A8-463A-9304-CBCD85BCB726When the brake is repeatedly applied at high
loads during the cold season, small cracks of
approximately 0.12 in (3 mm) long may appear
around the cross drilled holes
*A. This is due to
the temperature differential that occurs because
the surfaces of the disc rotors become hot while
the inside of the rotor is still cold. However, this
poses no problem in terms of brake perfor-
mance, and does not indicate a malfunction. The
brakes do not need to be replaced.
However, if the cracks extend to 0.16 in (4 mm)
or longer after repeated application of the
brakes at high loads during high performance driving, or through the continued use of the
brakes, the disc rotors must be replaced.
Brake dustGUID-31C6B056-A0D5-45B1-BD51-4A89044A64F5This vehicle is equipped with high performance
brakes, and the characteristics of the brake pad
material may cause more brake dust than other
vehicles. NISSAN recommends a wheel coating
that helps prevent the brake dust from sticking
to the wheels. It is recommended you contact a
GT-R certified NISSAN dealer for more details.
CHANGE OF SURFACE COLOR OF
TITANIUM MUFFLER (if so
equipped)
GUID-5B721A31-EAA5-4BAB-9A80-F6E9391F6A57Genuine titanium mufflers are made of titanium
alloy. The surface color will change depending
on the driving conditions, which is not unusual.
Prior to shipping from factory, all vehicles
receive balance aligning for engine, transmis-
sion, and clutch, as well as quench driving of
brake pads and rotors. As a result, the muffler
surface color may differ depending on the
vehicle.

SOUND HEARD AROUND TITANIUM
MUFFLER (if so equipped)
GUID-3D6A36AC-35D0-429E-A25B-64BE52267EDAWhen stopping the engine (rapid cooling) , you
may hear a metal-rubbing sound or unusual
ticking sound because of the differential thermal
expansion between the inner and outer pipes of
the muffler. This is not a malfunction. The sound
will decrease when the temperature lowers.
EXHAUST GAS IS NOT EMITTED
FROM LEFT EXHAUST PIPE DUR-
ING IDLING/WHEN ENGINE SPEED
IS LOW (if so equipped)
GUID-B888B87B-C622-4885-BBEB-1AE26168370BThe titanium muffler for vehicles with the exhaust
sound control system is equipped with a control
valve installed on the left-side exhaust pipe.
When the exhaust sound control switch is ON or
the engine speed is low, exhaust sound silen-
cing is enhanced by closing the valve. Exhaust
gas is not emitted from the left-side exhaust pipe
when the control valve is closed. This is not a
malfunction. (

temº page 5-58)
DRY CARBON FIBER PARTS (if so
equipped)
GUID-362B4E4E-C187-4858-A8A5-0C4269F48697Roughness or uneven surfaces of dry
carbon fiber parts and fiber twists
The surfaces of the dry carbon fiber parts are
lightly coated like a race car so that you can feel
the proper texture of real carbon, which may feel
rough. This is normal.
GUID-08C4CDAB-367E-4CFA-A36B-ADDE97035C59The GT-R dual clutch transmission is a newly-
developed system that uses an electronically
controlled multiple-disc wet clutch attached to
the highly efficient manual transmission. This
transmission has two driving modes.
.
&Aposition (Automatic gearshift):
allows automatic shifting of the manual
transmission.
.
&Mposition (Manual gearshift):
allows quick shifting of the manual transmis-
sion.
NOTE:
When starting or driving on a steep uphill
grade, shift to the
&Mposition and operate
the paddle shifter to shift down to 1st gear
similar to a manual transmission vehicle.

TRANSMISSION OPERATION CHARACTERISTICSGUID-DC9FD7D2-9CD4-46F9-AFB8-A7B5A93B4FE1
MechanismOperation characteristics
Base Manual transmission
.The GT-R transmission design is different from transmissions used in conventional passenger cars. The GT-R uses a transmission gear
design, light flywheel and a dry sump lubrication system to provide maximum vehicle performance. Because the GT-R Transmission design
is different, noises may be louder. When the transmission temperature is high, rattling, shaking and jarring noises may be heard.
.Clattering noises may be heard while shifting..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.
.If the shift lever is moved from&Rto&A
F&Mposition, or&A
F&Mto&Rposition before the vehicle stops, 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.
Multiple-disc wet clutch
.When stopping the vehicle with the shift lever in the&Ror&A
F&Mposition, be sure to firmly depress the brake pedal. The vehicle may
slowly move if the brake pedal is not depressed.
.Avoid depressing the brake and accelerator pedals at the same time. Depressing the brake and accelerator pedals at the same time could
cause the clutch to overheat and accelerate deterioration.
.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 oil 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 oil returns to normal operating temperatures.
.When the transmission oil 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..The quickest 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.
Mechanical Limited Slip
Differential (LSD) If the vehicle accelerates from a stop with the steering wheel turned half a turn in cold temperatures, the inner wheel tire may slip and some
noise or vibration may be heard. This phenomenon occurs because the viscosity of the differential oil becomes thicker and the Limited Slip
Differential (LSD) operates with increasing load. When the steering wheel is returned to the straight ahead position or the differential oil warms
up, the noise and vibration decrease.

5-44Starting and driving
GUID-91FE12D0-B396-43FF-9FAE-ED6A40FE9DF2The 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.

Warranty Information Booklet.
. Always use tires of the specified
type, size, brand, construction (bias,
bias-belted, radial or run-flat) , and
tread pattern on all four wheels.
Failure to do so may result in a
circumference difference between
tires on the front and rear axles
which will cause excessive tire wear
and may damage the transmission,
transfer case and differential gears.
Wheel balanceGUID-22867962-AD6F-48F7-AC6D-26DC40810782Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can
get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the rear wheels on the vehicle could lead to
mechanical damage.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada) in the War-
ranty Information Booklet.
