are installed on the wheels. The tire
may slip on the wheel if the vehicle is
driven in these conditions before 48
hours have passed. If the tire slips on
the wheel, the wheel/tire assembly
will be out of balance and will require
rebalancing.
BrakesThe information and specifications in
this section apply only when engaging
in performance driving.
.Check for the heat deterioration of the
brakes and parts around the brakes.
. It is recommended that you remove
air from the brake system after any of
the following:
— When engaging in high perfor-
mance driving for the first time
after purchasing a new vehicle.
— After replacing the brake fluid.
— When engaging in high perfor- mance driving for a sustained per-
iod of time. It is recommended that
bleeding the brake be performed
when the brake calipers are hot
(about 212°F (100°C)). Brake pad break-in procedure:
NISSAN recommends that a special brake
pad break-in procedure be performed
before engaging in performance driving.
It is recommended you contact a GT-R
certified NISSAN dealer for details.

engine speed is 4,300 RPM
. Revving the engine when the engine
oil is at a low (below 32°F (0°C)) or
extremely high (over 275°F (135°C))
temperature: The maximum engine
speed is 4,000 RPM (The

ENGINE OUTPUT
High altitudeTo protect the engine, engine output is
controlled so that it does not increase at
altitude of approximately 3,281 ft (1,000
m) or higher.Engine output according to the
coolant temperatureThe engine output is controlled at a low
level when the engine coolant tempera-
ture is lower than approximately 158°F
(70°C) or higher than 230°F (110°C). This is
not a malfunction. If the temperature is lower than approxi-
mately 158°F (70°C), drive the vehicle until
it reaches normal operating temperature.
If the temperature is higher than 230°F
(110°C), perform cool-down driving proce-
dure. (
“Cool down” page GTR-14)
When the temperature of the engine
coolant is between 158°F (70°C) and
230°F (110°C), the engine output returns
to normal.
UNEVEN WEAR OF TIRESThe GT-R is equipped with high perfor-
mance, 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

is started.
If any malfunction occurs in the AWD
system while the engine is running, the
warning light will come on.
The warning light may blink rapidly
(about twice per second) while trying to
free a stuck vehicle due to high AWD
clutch temperature. The driving mode
may change to two-wheel drive. If the
warning light blinks rapidly during opera-
tion, stop the vehicle with the engine
idling in a safe place immediately. Then if
the light goes off after a while, you can
continue driving.
A large difference between the diameters
of front and rear wheels will make the
warning light blink slowly (about once per
two seconds). Pull off the road in a safe
area, and idle the engine. Check that all
tire sizes are the same, tire pressure is
correct and tires are not worn and winter
tires are not installed on the front or rear
wheels only.
If the warning light is blinking after the
above operation, it is recommended you
have your vehicle checked by a GT-R
certified NISSAN dealer as soon as possi-
ble.
If non-genuine GT-R tires are used, the
warning light may illuminate. (

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.

NOTICE
Make sure the tire valve stem cap is
installed and that the valve stem is
tight. When installing the cap, make
sure to tighten the cap by hand. If a
tool is used to tighten the cap, the
cap may be damaged.TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires. When
the low tire pressure warning light is lit,
one or more of your tires is significantly
under-inflated. The system also displays
pressure of all tires on the touch screen
display by sending a signal from a sensor
that is installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not
detect a sudden drop in tire pressure.
(
“Low tire pressure warning light”
page 2-30) (
“Tire Pressure Monitoring
System (TPMS)” page 5-4) (
“Flat tire”
page 6-3)
Tire inflation pressure
Check the tire pressure often and
always prior to long distance trips.
The recommended tire pressure
specifications are shown on the F.
M.V.S.S./C.M.V.S.S. label or the Tire
and Loading Information label (if so
equipped) under the “Cold Tire
Pressure” heading. The Tire and
Loading Information label is affixed
to the driver side door end. Tire
pressures should be checked reg-
ularly because:.
Most tires naturally lose air over
time.
.
Tires can lose air suddenly when
driven over potholes or other
objects or if the vehicle strikes
a curb while parking.
NOTE:
. You can check the pressure of all
four tires on the touch screen dis-
play. See the separate Multi Func-
tion Display Owner’s Manual.
. The tires of this vehicle are filled
with nitrogen gas. When the tire
pressure is low, fill the tires with nitrogen. It is recommended you
contact a GT-R certified NISSAN
dealer for information on filling the
tires with nitrogen.
. If nitrogen is not available, com-
pressed air may be safely used
under normal driving conditions.
However, NISSAN recommends re-
filling with nitrogen for maximum
tire performance.
The tire pressures should be
checked when the tires are cold.
The tires are considered COLD after
the vehicle has been parked for 3 or
more hours, or driven less than 1
mile (1.6 km) at moderate speeds.
Incorrect tire pressure, including
under inflation, may adversely
affect tire life and vehicle hand-
ling.
WARNING
.
Improperly inflated tires can
fail suddenly and cause an
accident.
.
The Gross Vehicle Weight
rating (GVWR) is located on

the F.M.V.S.S./C.M.V.S.S. cer-
tification label. The vehicle
weight capacity is indicated
on the Tire and Loading In-
formation label (if so
equipped). Do not load your
vehicle beyond this capacity.
Overloading your vehicle
may result in reduced tire
life, unsafe operating condi-
tions due to premature tire
failure, or unfavorable hand-
ling characteristics and
could also lead to a serious
accident. Loading beyond
the specified capacity may
also result in failure of other
vehicle components.
.
Before taking a long trip, or
whenever you heavily load
your vehicle, use a tire pres-
sure gauge to ensure that
the tire pressures are at the
specified level.
.
For additional information
regarding tires, refer to “Im-
portant Tire Safety Informa-tion” (US) or “Tire Safety
Information” (Canada) in the
Warranty Information Book-
let.
NOTE:
.
Use only genuine GT-R tires and
road wheels.
The GT-R uses specially designed
run-flat tires and matching road
wheels. Use of these specially devel-
oped tires and wheels provides the
greatest potential for maximum
performance.
—Genuine GT-R tires and road
wheels help achieve maximum
cornering and braking perfor-
mance.
— Genuine GT-R tires and road
wheels help achieve maximum
tire durability during acceleration.
— Genuine GT-R tires and road
wheels help achieve maximum
handling capability during perfor-
mance driving.
— Genuine GT-R tires and road
wheels help provide road holding
in the event of decreasing tire
pressure and punctures. —
Genuine GT-R tires and road
wheels help prevent the decrease
of straight-running stability
caused by uneven tire wear due
to high rigidity wheels and wide
tires.
. The GT-R uses specially designed
run-flat tires which feature an ex-
tremely rigid side wall. Special tech-
niques and equipment are therefore
required when replacing these tires.
NISSAN recommends that tire repla-
cement be performed at a GT-R
certified NISSAN dealer.
. Specific tire changing equipment
must be used to remove the GT-R
tires from the wheel and to install
the GT-R tires onto the wheel. It is
only possible to reuse the tires when
they have no cracks and/or defor-
mations on the bead portion of the
tire. If the incorrect equipment is
used to remove the GT-R tires from
the wheel and to install the GT-R
tires onto the wheel, cracks and
deformation may occur on the bead
portion of the tires meaning that the
tires cannot be reused. It is recom-
mended you contact a GT-R certified
NISSAN dealer if the tires need to be
removed from the wheels.
