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

PARKING BRAKE BREAK-INBreak in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums/rotors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service manual and can be performed by a
GT-R certified NISSAN dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire chains.
Alwaysmaintainasafedistance
from the vehicle in front of you.
Ultimately, the driver is responsible
for safety.
. Tire type and condition may also
affect braking effectiveness. When
replacing tires, install the specified
size of tires on all four wheels.
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces. The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the systemDepress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.Self-test featureThe ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This does not indicate that there is
a malfunction. If the computer senses a mal-
function, it switches the ABS off and illuminates

. 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

. 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.

TYPES OF TIRES
WARNING
.When changing or replacing tires,
be sure all four tires are of the same
type (Examples: Summer or All
Season) and construction. A GT-R
certified NISSAN dealer may be able
to help you with information about
tire type, size, speed rating and
availability.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in the
Warranty Information Booklet.All-season tiresNISSAN specifies all-season tires on some
models to provide good performance for use
all year around, including snowy and icy road
conditions. All-season tires are identified by ALL
SEASON on the tire sidewall.
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 32 8F(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.Run-flat tiresYour vehicle is equipped with run-flat tires. You
can continue driving to a safe location even if
they are punctured. Always use run-flat tires of
the specified size on all four wheels. Mixing tire
sizes or construction may reduce vehicle hand-
ling stability. If necessary, contact a GT-R
certified NISSAN dealer for assistance. Frequently check the tire pressure information
display on the monitor screen and adjust
pressure of each tire properly. See the separate
Multi Function Display Owner’s Manual.
It can be difficult to tell if a run-flat tire is under-
inflated or flat. Check the tire pressures as
described earlier in this section. If the tire
becomes under-inflated while driving, the low
tire pressure warning light will come on. If the
tire becomes flat while driving, the low tire
pressure warning light and the run-flat tire
warning display will come on.
Low tire pressure:If the vehicle is being driven with low tire
pressure, the low tire pressure warning light will
illuminate.Flat tire:If the vehicle is being driven with one or more flat
tires, the run-flat tire warning display will appear
continuously on the vehicle information display
and a chime will sound for 10 seconds.
The chime will only sound at the first indication
of a flat tire and the run-flat tire warning display
will illuminate continuously. When the flat tire
warning is activated, have the system reset and
the tire checked and replaced if necessary by a
GT-R certified NISSAN dealer. Even if the tire is
inflated to the specified COLD tire pressure, the
warning light will continue to illuminate until the
system is reset by a GT-R certified NISSAN

dealer.
If the low tire pressure and the run-flat tire
warning appears on the vehicle information
display:
.Do not exceed 50 MPH (80 km/h) .
. Increase your following distance to allow for
increased stopping distances.
. Avoid sudden maneuvers, hard cornering
and hard braking.
WARNING
.Although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling sta-
bility is reduced, which could lead to
an accident and personal injury.
Also, driving a long distance at high
speeds may damage the tire.
. Do not drive at speeds above 50
MPH (80 km/h) and do not drive
more than 50 miles (80 km) with a
punctured run-flat tire. The actual
distance the vehicle can be driven
on a flat tire depends on outside
temperature, vehicle load, road con-
ditions and other factors.
. Drive safely at reduced speeds. Avoid hard cornering or braking,
which may cause you to lose control
of the vehicle.
NOTICE
.
Never install tire chains on a punc-
tured run-flat tire, as this could
damage your vehicle.
. Avoid driving over any projection or
pothole, as the clearance between
the vehicle and the ground is smal-
ler than normal.
. Do not enter an automated car wash
with a punctured run-flat tire.
. Have the punctured tire replaced by
a GT-R certified NISSAN dealer as
soon as possible, as the tire’s
performance capability is reduced.Tires for All-Wheel Drive (AWD)If excessive tire wear is found, it is recom-
mended that all four tires be replaced with tires
of the specified size, brand, construction and
tread pattern. The tire pressure and wheel
alignment should also be checked and cor-
rected as necessary. Contact a GT-R certified
NISSAN dealer.
TIRE CHAINSUse of tire chains may be prohibited according
to location. Check the local laws before instal-
ling tire chains. When installing tire chains, make
sure they are of proper size for the tires on your
vehicle and are installed according to the chain
manufacturer instructions. Use only SAE class
S chains. Class “S” chains are used on vehicles
with restricted tire to vehicle clearance. Vehicles
that can use Class “S” chains are designed to
meet the SAE standard minimum clearances
between the tire and the closest vehicle
suspension or body component required to
accommodate the use of a winter traction device
(tire chains or cables) . The minimum clearances
are determined using the factory equipped tire
size. Other types may damage your vehicle. Use
chain tensioners when recommended by the tire
chain manufacturer to ensure a tight fit. Loose
end links of the tire chain must be secured or
removed to prevent the possibility of whipping
action damage to the fenders or undercarriage.
If possible, avoid fully loading your vehicle when
using tire chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be da-
maged and/or vehicle handling and performance
may be adversely affected.NOTE:Tire chains must be installed only on the
rear wheels and not on the front wheels.

WARNING
. The use of tires other than those
specified or the mixed use of tires of
different brands, construction (bias,
bias-belted, radial or run-flat) , or
tread patterns can adversely affect
the ride, braking, VDC system, hand-
ling, ground clearance, body-to-tire
clearance, tire chain clearance,
speedometer calibration, headlight
aim and bumper height. Some of
these effects may lead to accidents
and could result in serious personal
injury.
. If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics, affect the VDC system and/or
cause interference with the brake
discs. Such interference can lead to
decreased braking efficiency and/or
early brake pad wear. (
“WHEELS AND TIRES” page

. When a wheel is replaced, tire
pressure will not be indicated, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute and
remain on after the 1 minute. Con-
tact a GT-R certified NISSAN dealer
as soon as possible for tire replace-
ment and/or system resetting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
. Never use retread tires.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in the
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 balanceUnbalanced 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 “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the War-
ranty Information Booklet.Care of wheels.
Wash the wheels when washing the vehicle
to maintain their appearance.
. Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
