.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See the "9. Main-
tenance and schedules" section for main-
tenance intervals. When replacing the filter, wipe the inside of the air cleaner
housing and the cover with a damp cloth.

being uninstalled from the
wheels, use equipment such as a
leverless automatic tire changer.
It is only possible to reuse the
tires when they have no cracks
and/or deformations on the bead
portion. However, if you use a
lever-type tire 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 ad-
versely affect the ride, braking,
VDC system, handling, ground
clearance, body-to-tire clearance, tire chain clearance, speed-
ometer calibration, headlight
aim and bumper height. Some of
these effects may lead to acci-
dents 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 dimension. Wheels of a differ-
ent off-set could cause prema-
ture tire wear, degrade vehicle
handling characteristics, 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 10-
10)
. 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. It is recommended you
contact a GT-R certified NISSAN
dealer as soon as possible for tire
replacement and/or system re-
setting. .
Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. The TPMS sensor may be da-
maged if it is not handled cor-
rectly. Be careful when handling
the TPMS sensor.
. When replacing the TPMS sensor,
the ID registration may be re-
quired. Contact a GT-R certified
NISSAN dealer for ID registration.
. Do not use a valve stem cap that
is not specified by NISSAN. The
valve stem cap may become
stuck.
. Be sure that the valve stem caps
are correctly fitted. Otherwise the
valve may be clogged up with dirt
and cause a malfunction or loss
of pressure.
. Do not install a damaged or
deformed 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 re-

in this section for 48 hours after tires
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.

Do not lean against doors or windows.
WARNING
Front seat-mounted side-impact
supplemental air bags and roof-
mounted curtain side-impact and
rollover supplemental air bags :
.The side air bags ordinarily will
not inflate in the event of a front
impact, rear impact, rollover, or
lower severity side collision. Al-
ways wear your seat belts to help
reduce the risk or severity of
injury in various kinds of acci-
dents.
. The curtain air bags ordinarily will
not inflate in the event of a front
impact, rear impact, or lower
severity side collision. Always
wear your seat belts to help
reduce the risk or severity of
injury in various kinds of acci-
dents.
. The seat belts, side air bags and
curtain air bags are most effec-
tive when you are sitting well
back and upright in the seat. The
side air bags and curtain air bags
inflate with great force. Do not
allow anyone to place their hand,
leg or face near the side air bag

on the side of the seatback of the
front seat or near the side roof
rails. Do not allow anyone sitting
in the front seat to extend their
hand out of the window or lean
against the door. Some examples
of dangerous riding positions are
shown in the previous illustra-
tions.
. When sitting in the rear seat, do
not hold onto the seatback of the
front seat. If the supplemental
side air bag inflates, you may be
seriously injured. Be especially
careful with children, who should
always be properly restrained.
Some examples of dangerous
riding positions are shown in the
illustrations.
. Do not use seat covers on the
front seatbacks. They may inter-
fere with side air bag inflation.

7. Check to make sure the child restraintis properly secured prior to each use. If
the child restraint is loose, repeat
steps 1 through 6.
WARNING
The three-point seat belt with Auto-
matic Locking Retractor (ALR) must
be used when installing a child re-
straint. Failure to use the ALR mode
will result in the child restraint not
being properly secured. The restraint
could tip over or be loose and cause
injury to a child in a sudden stop or
collision. Also, it can change the
operation of the front passenger air
bag. See “Front passenger air bag
and status light” later in this section.

NOTICE
Some cleaners may cause the paint
to peel or cause spots to occur. If
using a cleaner, it is recommended
you consult with a GT-R certified
NISSAN dealer.
MOST COMMON FACTORS CON-
TRIBUTING TO VEHICLE CORRO-
SION.The accumulation of moisture-retain-
ing dirt and debris in body panel
sections, cavities, and other areas.
. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor traffic accidents.ENVIRONMENTAL FACTORS IN-
FLUENCE THE RATE OF CORRO-
SION
MoistureAccumulation of sand, dirt and water on
the vehicle body underside can acceler-
ate corrosion. Wet floor coverings will not
dry completely inside the vehicle, and
should be removed for drying to avoid
floor panel corrosion.Relative humidityCorrosion will be accelerated in areas of
high relative humidity, especially those
areas where the temperatures stay above
freezing where atmospheric pollution ex-
ists, or where road salt is used.
TemperatureA temperature increase will accelerate
the rate of corrosion to those parts which
are not well ventilated.Air pollutionIndustrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use will accelerate the corrosion process.
Road salt will also accelerate the disin-
tegration of paint surfaces.TO PROTECT YOUR VEHICLE FROM
CORROSION.Wash and wax your vehicle often to
keep the vehicle clean.
. Always check for minor damage to the
paint and repair it as soon as possible.
. Keep drain holes at the bottom of the
doors open to avoid water accumula-
tion.
. Check the underbody for accumula-
tion of sand, dirt or salt. If present,
wash with water as soon as possible.

position.
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other
moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed space such as a garage,
be sure there is proper ventilation
for exhaust gases to escape.
. Never get under the vehicle while
it is supported only by a jack. If it
is necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid
injury, always disconnect the ne-
gative battery cable before work-
ing near the fan.
. The fuel filter or fuel lines should
be serviced by a GT-R certified
NISSAN dealer because the fuel
lines are under high pressure
even when the engine is off.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.
NOTICE
.Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or trans-
mission related component har-
nesses disconnected while the
ignition switch is in the ON posi-
tion.

MAINTENANCE PRECAUTIONS

, open the
reservoir cap (pressure type)and add
coolant up to between the MAX
and
MIN
level. If the reservoir is empty, open
the radiator filler cap
and check the
coolant level in the radiator when the
engine is cold. If there is insufficient
coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to between
the MAX
and MIN
level. This vehicle contains Genuine NISSAN
Long Life Antifreeze/Coolant (blue). The
life expectancy of the factory-fill coolant
is 24,000 miles (38,400 km) or 2 years.
Mixing any other type of coolant or the
use of non-distilled water will reduce the
life expectancy of the factory-fill coolant.
Refer to the “9. Maintenance and sche-
dules” section of this manual for more
details.
If the cooling system frequently re-
quires coolant, it is recommended you
have it checked by a GT-R certified
NISSAN dealer.
Check that the level of coolant is between
MAX and MIN on the pressurized radiator
reservoir. If the level is below the mid-
point, the amount of coolant circulating
may be insufficient for maximum vehicle
performance, possibly causing engine
overheating or other trouble.
For the coolant level and mixture ratio
when engaging in performance driving,
see
“Coolant level and mixture ratio”
page GTR-15.
Except for NISMO models:
If it is difficult to determine the midpoint
between MAX and MIN, remove the cool-
ant reservoir cap and look inside through
the opening to check that the coolant
level is above the divider
between the
top half and bottom half of the pressur- ized coolant reservoir.
NOTICE
.
The coolant reservoir is equipped
with a pressure type cap, and the
radiator is equipped with a non-
pressure type cap. Do not switch
the radiator filler cap and the
coolant reservoir cap. Doing so
will cause substandard cooling
performance and overheating.
. If you have added only water as
the coolant in an emergency,
change it to a coolant mixture
ratio specified as soon as possi-
ble.CHANGING ENGINE COOLANTIf major cooling system repairs are re-
quired, it is recommended you contact a
GT-R certified NISSAN dealer. The service
procedures can be found in the appro-
priate NISSAN Service Manual.
Improper servicing can result in re-
duced heater performance and engine
overheating.
