The GT-R is NISSAN’s first supercar category
vehicle. The GT-R is equipped with special
systems. These systems are different than those
used on conventional vehicles to allow for the
high performance driving characteristics of this
vehicle. Your vehicle should be maintained by a
GT-R certified NISSAN dealer. Special skills,
knowledge and equipment are necessary to
properly maintain your GT-R.WARRANTY INFORMATIONPlease read this OM carefully, together with your
Warranty Information Booklet which describes a
number of express limitations and exclusions for
failure to follow the instructions contained in this
OM, including, but not limited to:
.Failure to use proper parts, fuel and fluids,
. Driving with the VDC off,
. Racing,
. Modifications, including reprogramming or
replacing/adding chips in any on-board
computer,
. Failure to have required Performance Opti-
mization Services performed.
In addition, see your Dunlop/Goodyear and
Bridgestone tire warranties for specific limita-
tions or exclusions for operating summer tires
below 48F( 20 8C) .
MAINTENANCE INFORMATION. Special skills, knowledge and equipment are
necessary to properly inspect and adjust the
GT-R engine, transmission, suspension and
brakes to maintain performance. A GT-R
certified NISSAN dealer has the GT-R
certified technical staff and the special
equipment to properly maintain your GT-R.
. Many general periodic maintenance items
can be performed at all NISSAN dealers.
However, make sure the specified fluids and
parts are used when the maintenance is
performed.
Only use the following required fluids and parts
in the GT-R.ENGINE OILMobil 1, 0W-40 (100% synthetic oil)
Mobil 1, 0W-40 (100% synthetic) is the factory
fill oil. The VR38 engine with its plasma-sprayed
bores was developed using this oil. NISSAN
cannot ensure proper engine operation and
durability if other 0W-40 synthetic oil is used.
If Mobil 1, 0W-40 is not available, Mobil 1,
10W-40 (100% synthetic) may be used; how-
ever, some performance loss may be noticed.TRANSMISSION OILGenuine NISSAN Transmission Oil R35
Special (100% synthetic oil)
The GT-R uses a multiple-disc dual wet clutch
transmission. The specially developed transmis-
sion oil maximizes the friction characteristics of
the clutch and the lubrication of the gear
bearings. The use of additives is prohibited.DIFFERENTIAL OIL (front and rear)Castrol SAF-XJ 75W-140 (100% synthetic
oil)
The GT-R uses a 1.5-Way mechanical Limited
Slip Differential (LSD) to maximize driving power
under many operating conditions. Use the
specified differential oil to maximize the perfor-

mance of the LSD. Also use the same oil for the
front differential.The use of additives is
prohibited.BRAKE FLUIDGenuine NISSAN Brake Fluid R35 Special
DOT4
Genuine NISSAN Brake Fluid R35 Special
DOT4 is the factory fill brake fluid. The Vehicle
Dynamic Control (VDC) unit and other related
parts were specially designed for this brake
fluid. NISSAN cannot ensure the best perfor-
mance and proper operation of the vehicle if
other brake fluid is used.TIRES AND ROAD WHEELSGenuine GT-R tires and road wheels or
equivalent
Use only genuine GT-R tires and road wheels or
equivalent. Proper use of NISSAN recom-
mended tires provides the greatest potential
for maximum performance.
. Genuine GT-R tires and road wheels or an
equivalent help achieve maximum cornering
performance.
. Genuine GT-R tires and road wheels or an
equivalent help provide road holding in the
event of decreasing tire pressure and
punctures. .
Genuine GT-R tires and road wheels or an
equivalent help prevent the decrease of
straight-running stability caused by uneven
tire wear due to high rigidity wheels and
wide tires.
BRAKE PAD AND DISC ROTORGenuine GT-R brake pads and disc rotors
This vehicle is equipped with a high perfor-
mance braking system and includes cross-
drilled floating rotors and radial-mounted six-
piston monoblock calipers. This helps to achieve
excellent stopping performance and fade-resis-
tance. Replace all four sets of brake pads and
disc rotors at the same time to maintain
maximum brake performance.EXHAUST MUFFLERUse only the special GT-R muffler and
trunk carpet.
Never use parts other than genuine NISSAN
parts.
The GT-R has high exhaust gas temperatures. If
non-GT-R specification parts are used, it is
possible that the muffler will deform and cause
damage to the underbody. Also do not remove
the trunk carpet from the vehicle for any reason.
The carpet insulates the vehicle interior from the
heat of the muffler and from the noise of the
transmission.
EXTERIOR PARTS (spoiler, etc.)Do not modify exterior parts.
The GT-R was developed using a special wind
tunnel to help make sure the vehicle is
aerodynamically balanced. Additionally, the wind
tunnel was used to help make sure cool air flows
to the brakes, radiator and other components.
Additions of non-GT-R specific accessory ex-
terior parts can change the air flow over and
around the body. This can affect vehicle balance
and cooling of various systems.
For example, if the front bumper is modified,
there is a possibility that brake performance may
be reduced due to the decrease of the air flow to
the brake system.

INSPECTION AND ADJUSTMENTS
OF TIRES, SUSPENSION AND
BRAKES. Measure and adjust the wheel alignment.
. Check the tire pressure and the Tire
Pressure Monitoring System (TPMS) sen-
sor.
. Make tire pressure adjustments only when
the tires are cool. (
“WHEELS AND
TIRES” page 8-29)
. Secure road wheel balance weights with
aluminum tape or equivalent.
. Check the heat deterioration and wear of the
brakes. (As necessary, the brake pad and
the brake disc rotor must be replaced as a
set of four with new ones.)
REPLENISHING COOLANTCheck the coolant level in the pressurized
coolant reservoir. Adjust the level so that the
fluid is between the MAX and MIN markings. For
the coolant, use genuine NISSAN Long Life
coolant. (On delivery of new vehicle, the
reservoir is filled to the MIN level. Be sure to
replenish approximately 0.3 to 0.4 US quart (0.3
to 0.4 liter) of coolant.)

or oil is at a low or extremely high
temperature: The maximum engine speed
is 4,000 RPM
DISTORTION OF REAR WINGWhen the vehicle is parked in direct sunlight on
a hot day, the center of the rear wing may
become distorted. This is normal. When the
surface temperature of the rear wing is reduced,
the shape of the wing should return to normal.UNEVEN WEAR OF TIRESThe NISSAN GT-R is equipped with high
performance, low profile, run-flat tires that are
optimized for performance and handling. The life
of these tires will be less than those of tires
installed on a typical vehicle, and you are likely to
experience uneven tire wear and tire noise
regardless of the type of tire used.NOISES ARE HEARD WHILE DRIV-
ING.The GT-R brake pads use material that
provides a high amount of braking power
even in high temperatures. This material can
cause an intermittent screeching noise when
the brakes are applied. The noise decreases
as the brake pads wear. .
A screeching noise may be heard when the
brake pedal is depressed:
— When driving the vehicle for the first time in the morning,
— After leaving the vehicle parked for extended periods of time, or
— When the vehicle is damp following rain showers or washing the vehicle.
These sounds are normal. The noise is
caused when the brake pads absorb moist-
ure, and the noise stops after the brake is
applied several times.
. A screeching noise may also be heard when
the brake pedal is depressed:
— When repeatedly applying gentle brak- ing, especially on a curve at a low
speed, or
— When the brake rotors have circular scores with the brake temperature high.
. To maintain steady braking performance in
both extremely high and low temperatures,
the gap between the brake pad and caliper
is larger than normal and large-size brake
pads are used. When driving over a bump, a
light rattling sound may be heard from the
brake pad. This does not indicate that there
is a malfunction. .
When the brake disc rotor undergoes
thermal expansion, a rumbling noise may
be heard from the engaging portion of the
wheel and the brake disc rotor. This does
not indicate that there is a malfunction. The
noise will cease when the temperature
decreases.
. In addition to noise resulting from uneven
tire wear discussed in the previous section,
the GT-R tires are more rigid than a typical
passenger car tire and are made from a
specially formulated rubber to maximize the
vehicle’s performance capabilities. These
characteristics cause the GT-R tires to have
more road noise than a typical passenger
car tire. This road noise is normal.
. Due to the performance capabilities and
requirements of the GT-R, the sequential 6-
speed dual clutch transmission is unlike a
typical automatic transmission. You will likely
hear mechanical sounds from the transmis-
sion, particularly at slow speeds and at idle.
This condition is normal.GTR-8

BRAKE DUSTThis 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. Contact a GT-R certified NISSAN
dealer for more details.MECHANICAL LIMITED SLIP DIF-
FERENTIAL (LSD) CHARACTERIS-
TICSThe differential oil has a high viscosity and is
very thick when cold. 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 Limited Slip Differential (LSD). When
the steering wheel is returned to the straight-
ahead position or the differential oil warms up,
the noise and vibration decrease.
The 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.
.
&M
position (Manual gearshift):
allows quick shifting of the manual transmis-
sion.
NOTE:.
&M
position driving is recommended
when driving up hills or accelerating
from a stop on a cold morning.
.
&M
position driving is recommended if
you feel shift shocks or jerkiness in the
&Aposition in cold temperatures.
. 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 similar to a manual
transmission vehicle.
The GT-R dual clutch transmission was devel-
oped specifically to maximize vehicle perfor-
mance 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 of the follow-
ing items:
.
Gear clearances
. Ultralight flywheel
. Dry sump lubrication
These noises do not indicate that there is a
malfunction.

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.

AUDIBLE REMINDERS
Key reminder chimeA chime will sound if the driver side door is
opened while the ignition switch is pushed to
the ACC position or pushed to the OFF or
LOCK position with the Intelligent Key left in the
Intelligent Key port. Make sure the ignition
switch is pushed to the OFF position, and take
the Intelligent Key with you when leaving the
vehicle.Light reminder chimeA chime will sound when the driver side door is
opened with the light switch in the
or
position and the ignition switch in the ACC, OFF
or LOCK position.
Turn the light switch off when you leave the
vehicle.Parking brake reminder chimeA chime will sound if the vehicle speed is above
4 MPH (7 km/h) with the parking brake applied.
Stop the vehicle and release the parking brake.Brake pad wear warningThe disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound when
the vehicle is in motion. This scraping sound will
first occur only when the brake pedal is
depressed. After the wear of the brake pad is
increased, the sound will be heard all the timeeven if the brake pedal is not depressed. Have
the brakes checked as soon as possible if the
warning sound is heard.2-30

significantly more likely to be injured or
killed than a person properly wearing a
seat belt.OFF-ROAD RECOVERYWhile driving, the right side or left side wheels
may unintentionally leave the road surface. If this
occurs, maintain control of the vehicle by
following the procedure below. Please note that
this procedure is only a general guide. The
vehicle must be driven as appropriate based on
the conditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheelwith both hands and try to hold a straight
course.
4. When appropriate, slowly release the accel- erator pedal to gradually slow the vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the vehicle
speed is reduced. Do not attempt to drive
the vehicle back onto the road surface until
vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return to the
road surface. When all tires are on the road
surface, steer the vehicle to stay in the
appropriate driving lane. .
If you decide that it is not safe to return
the vehicle to the road surface based on
vehicle, road or traffic conditions, gra-
dually slow the vehicle to a stop in a safe
place off the road.
RAPID AIR PRESSURE LOSSRapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged due
to hitting a curb or pothole. Rapid air pressure
loss can also be caused by driving on under-
inflated tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at highway
speeds.
Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspect the tires for wear and damage.
(
“WHEELS AND TIRES” page 8-29)
If a tire rapidly loses air pressure or “blows-out”
while driving maintain control of the vehicle by
following the procedure below. Please note that
this procedure is only a general guide. The
vehicle must be driven as appropriate based on
the conditions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if there is a sudden loss of tire air
pressure. Losing control of the vehicle
may cause a collision and result in
personal injury.
.
The vehicle generally moves or pulls
in the direction of the flat tire.
. Do not rapidly apply the brakes.
. Do not rapidly release the accelera-
tor pedal.
. Do not rapidly turn the steering
wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
3. When appropriate, slowly release the accel- erator pedal to gradually slow the vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from traffic if possible.
5. Lightly apply the brake pedal to gradually stop the vehicle.
6. Turn on the hazard warning flashers and contact a roadside emergency service to
change the tire.

Never shift to the
&P
or
&A↔&M
position while the vehicle is moving
rearward. Doing so could cause loss
of control and an accident.
. The shift lever contains a powerful
magnet. Do not place electronic
medical devices or other electronic
products that are susceptible to
magnetic force close to the shift
lever.
CAUTION
.Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
. Because the vehicle includes a dual
clutch transmission that automati-
cally controls the clutch and shifting
operation of the manual transmis-
sion, whenever the shift lever is in a
position other then
&P
or
&N, 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 circum-
stances the vehicle may not start moving on its own, however this
does not indicate that there is a
malfunction.
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.
Operating the shift leverAfter starting the engine, fully depress the brake
pedal and move the shift lever from the
&P
position to the
&R,&N,or
&A↔&M
position. Push
the button to shift into the
&Por&Rposition. All
other positions can be selected without pushing
the button.
