8-4Maintenance and do-it-yourself
During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have a
GT-R certified NISSAN dealer do it promptly. In
addition, you should notify a GT-R certified
NISSAN dealer if you think that repairs are
required. (

EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following
items with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood: Check that all doors
and the engine hood, operate properly. Also
ensure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary latch
keeps the hood from opening when the primary
latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication frequently. Lights*:
Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires cannot be rotated because
your vehicle is equipped with different sized tires
in the front and rear.
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If
necessary, adjust the pressure in all tires to the
pressure specified. Check carefully for damage,
cuts or excessive wear.
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.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace grommet
seal of transmitter in TPMS, when replacing
each tire by reaching the wear limit.
Tire, wheel alignment and balance: If the
vehicle should pull to either side while driving on
a straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the War-
ranty Information Booklet.
Windshield: Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
GENERAL MAINTENANCE

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
help achieve maximum handling
capability during performance driv-
ing.
— 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.

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 aGT-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 CHAINS
Use 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.
CAUTION
Do not use tire chains on dry roads.
NOTICE
Never install tire chains on a punctured
run-flat tire, as this could damage your
vehicle.
Do not drive with tire chains on paved roads that
are clear of snow. Driving with chains in such
conditions can cause damage to the various
mechanisms of the vehicle due to some
overstress.
CHANGING WHEELS AND TIRES
Tire rotation
Tires cannot be rotated because your
vehicle is equipped with different sized
tires in the front and rear.
Maintenance and do-it-yourself8-39

changer, cracks and deformation
may occur on the bead portion of
the tires meaning that the tires
cannot be reused.
. 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.
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 9-9)
. 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 balance
Unbalanced 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.

8. With the wheel nut wrench, tighten wheelnuts alternately and evenly in the sequence
as illustrated (
*1,*2,*3,*4,*5) until
they are tight.
9. Lower the vehicle slowly until the tire touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence as illustrated. Lower the
vehicle completely.
WARNING
.Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
. Do not use oil or grease on the
wheel studs or nuts. This could
cause the nuts to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600
miles (1,000 km) .
WARNING
If the road wheels are hot, allow them
to cool sufficiently before tightening
the wheel nuts. Otherwise, the wheel
nuts cannot be tightened to specifica-
tion. NOTE:
.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 97 ft-lb (132 N·m)
The wheel nuts must be kept tigh-
tened to specification at all times. It
is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD
pressure.
COLD pressure: After the vehicle has
been parked for three hours or more
or driven less than 1 mile (1.6 km) .
COLD tire pressures are shown on
the Tire and Loading Information
label affixed to the driver’s door
opening.
