5-4Starting and driving
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system com-
ponents.
. Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
NOTICE
.Do not use leaded gasoline. Depos-
its from leaded gasoline seriously
reduce the three-way catalyst’s abil-
ity to help reduce exhaust pollu-
tants.
. Keep your engine tuned up. Mal-
functions in the ignition, fuel injec-
tion, or electrical systems can cause
overrich fuel flow into the three-way
catalyst, causing it to overheat. Do
not keep driving if the engine mis-
fires, or if noticeable loss of perfor-
mance or other unusual operating conditions are detected. Have the
vehicle inspected promptly by a
GT-R certified NISSAN dealer.
. Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, dama-
ging the three-way catalyst.
. Do not race the engine while warm-
ing it up.
. Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire
inflation pressure label, you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires
is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
If the vehicle is being driven with one or more flat
tires, the run-flat tire warning light will illuminate
continuously and a chime will sound for 10
seconds. The chime will only sound at the first
indication of a flat tire, and the warning light 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. Your vehicle can be
driven for a limited time on a flat tire. (
“Run-
flat tires” page 8-37)
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.

Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indi-
cator is illuminated, the system may not be able
to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale
after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.Additional information
.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 (for example a
flat tire while driving) .
. The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h)
to activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
. Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. Altitude can
also affect tire pressure. These may cause
the low tire pressure warning light to
illuminate. If the warning light illuminates,
check the tire pressure for all four tires.
. GT-R vehicles are delivered from the factory
with nitrogen-filled tires. For best perfor-
mance, NISSAN recommends that GT-R
owners maintain their vehicles by using nitrogen for tire inflation. Because nitrogen
is more stable than compressed air, it is less
prone to pressure fluctuation resulting from
temperature variations. If nitrogen is not
available, compressed air may be safely
used under normal driving conditions. How-
ever, NISSAN recommends refilling with
Nitrogen for maximum tire performance.
. The Tire and Loading Information label (also
referred to as the vehicle placard or tire
inflation pressure label) is located in the
driver’s door opening.
. You can also check the pressure of all tires
on the multi function display. Refer to the
separate Multi Function Display Owner’s
Manual.
. The tire pressure sensor should be reset
anytime the wheels or tires are removed or
replaced.
. If the tire is removed in order to replace the
tire pressure sensor battery, it may not be
possible to reuse the removed tire from the
wheel. To replace the tire pressure sensor
battery, contact a GT-R certified NISSAN
dealer.
Starting and driving5-5

If you have a flat tire, see the following
section. (“Flat tire” page 6-2)
CAUTION
A GT-R certified NISSAN dealer should
perform a tire change. It will be neces-
sary to reset the tire pressure sensors.
To change the tires, contact a GT-R
certified NISSAN dealer.
Be sure to use the tires and wheels together as
a set that are designated for use with this
vehicle.
When tire replacement is required, replacing the
tires as a set of four with new tires is
recommended. 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
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 multi function
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 warn-
ing light” page 2-26) (“Tire Pressure
Monitoring System (TPMS)” page 5-4)
(
“Flat tire” page 6-2)
Tire inflation pressure
Check the tire pressure often and always
prior to long distance trips. The recom-
mended 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 Pres-
sure” heading. The Tire and Loading
Information label is affixed to the driver
side door end. Tire pressures should be
checked regularly 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 multi function display. See
the separate Multi Function 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. Contact
a GT-R certified NISSAN dealer for
information on filling the tires with
nitrogen.

.If nitrogen is not available, compressed
air may be safely used under normal
driving conditions. However, NISSAN
recommends refilling 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 un-
der inflation, may adversely affect tire
life and vehicle handling.
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. certification la-
bel. The vehicle weight capacity
is indicated on the Tire and
Loading Information label (if so
equipped) . Do not load your vehicle beyond this capacity.
Overloading your vehicle may
result in reduced tire life, unsafe
operating conditions due to pre-
mature tire failure, or unfavor-
able handling characteristics
and could also lead to a serious
accident. Loading beyond the
specified capacity may also re-
sult in failure of other vehicle
components.
.Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level.
.For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
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 developed tires
and wheels provides the greatest po-
tential for maximum performance.
—Genuine GT-R tires and road wheels
help achieve maximum cornering
and braking performance.
— Genuine GT-R tires and road wheels
help achieve maximum tire durabil-
ity during acceleration.
— Genuine GT-R tires and road wheels

this pressure when the tires are cold.
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. The recom-
mended cold tire inflation is set by the
manufacturer to provide the best bal-
ance of tire wear, vehicle handling,
driveability, tire noise, etc., up to the
vehicle’s GVWR.

1.Remove the valve stem cap from the
tire.
2.Press the pressure gauge squarely onto
the valve stem. Do not press too hard or
force the valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard while
checking the pressure, reposition the
gauge to eliminate this leakage.
3.Remove the gauge.
4.Read the tire pressure on the gauge
stem and compare it to the specifica-tion shown on the Tire and Loading
Information label.
5.Add air to the tire as needed. If too
much air is added, press the core of the
valve stem briefly with the tip of the
gauge stem to release pressure. Re-
check the pressure and add or release
air as needed.
6.Install the valve stem cap.
7.Check the pressure of all other tires.
NOTE:
.
You can check the pressure of all
four tires on the multi function
display. See the separate Multi
Function 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. 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.

Example
TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the side-
wall of all tires. This information identifies
and describes the fundamental character-
istics of the tire and also provides the tire
identification number (TIN) for safety stan-
dard certification. The TIN can be used to
identify the tire in case of a recall.
Example
1.Tire size (example: P215/65R15 95H)
a.P: The “P” indicates the tire is designed for passenger vehicles.
(Not all tires have this information.)
b.Three-digit number (215): This num-
ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
c.Two-digit number (65): This number, known as the aspect ratio, gives the
tire’s ratio of height to width.
d.R: The “R” stands for radial.
e.Two-digit number (15): This number
Maintenance and do-it-yourself8-35

8-36Maintenance and do-it-yourself
is the wheel or rim diameter in
inches.
f.Two- or three-digit number (95): Thisnumber is the tire’s load index. It is a
measurement of how much weight
each tire can support. You may not
find this information on all tires
because it is not required by law.
g.H: Tire speed rating. You should notdrive the vehicle faster than the tire
speed rating.
Example
2.TIN (Tire Identification Number) for a
new tire (example: DOT XX XX XXX
XXXX)
a.DOT: Abbreviation for the “Depart- ment of Transportation”. The symbol
can be placed above, below or to the
left or right of the Tire Identification
Number.
b.Two-digit code: Manufacturer’s iden-tification mark
c.Two-digit code: Tire size
d.Three-digit code: Tire type code(Optional)
e.Three-digit code: Date of Manufac-
ture
f.Four numbers represent the week and year the tire was built. For
example, the numbers 3103 means
the 31st week of 2003. If these
numbers are missing, then look on
the other sidewall of the tire.
3.Tire ply composition and material
The number of layers or plies of rubber-
coated fabric in the tire.
Tire manufacturers also must indicate
the materials in the tire, which include
steel, nylon, polyester, and others.
4.Maximum permissible inflation pressure
This number is the greatest amount of
air pressure that should be put in the
tire. Do not exceed the maximum
permissible inflation pressure.
5.Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can
be carried by the tire. When replacing
the tires on the vehicle, always use a
tire that has the same load rating as the
factory installed tire.
