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

Cool downThe information and specifications in
this section apply only when engaging
in performance driving.
Cool down the vehicle to help extend the
life of the vehicle if coolant temperatures
are extremely high. Drive the vehicle at 37
to 50 MPH (60 to 80 km/h), in 5th or 6th
gear for 2 to 3 miles (3 to 5 km) and then
stop the engine.Refueling precautions
WARNING
Do not attempt to top off the fuel
tank after the fuel pump nozzle
shuts off automatically. Continued
refueling may cause fuel overflow,
resulting in fuel spray and possibly a
fire. The fuel tank is full at the first
automatic shutoff.
To maximize vehicle performance, the
fuel tank is located as low as possible to
lower the vehicle center of gravity. The
tank is also divided into two parts. This
fuel tank design causes higher pressures
inside the tank than other vehicles so fuel
spillage is possible by trying to top off the fuel tank after automatic shutoff.
The fuel tank pressure is higher when the
vehicle is hot, especially if the tank is more
than half full. If the cap is opened when
the vehicle is hot, it may cause fuel spray
and there may be a hissing noise. Open
the cap slowly, releasing the pressure
from the tank gradually. Also, if the
vehicle is refueled when the vehicle is
hot, the fuel pump may automatically
shut off before the tank is full. This does
not indicate that there is a malfunction.
Refuel slowly or refuel after the vehicle
has cooled.
INSPECTION AND ADJUSTMENTS
BEFORE DRIVINGThe information and specifications in
this section apply only when engaging
in performance driving.Fluids.
Check the engine, transmission, differ-
ential and under vehicle surfaces for
oil and coolant leaks.
. Check the fluid levels and adjust as
necessary using the specified fluid as
described under the conditions listed
in this section.(
“Recommended
fluids and maintenance interval” page GTR-20) If you do not drive under the
conditions listed, refer to the “9. Main-
tenance and schedules” section of this
manual.

Check the coolant level in the pressurized
coolant reservoir. Adjust the level so that
the fluid is between the MAX and MIN
markings. For the coolant, use genuine
NISSAN Long Life coolant or equivalent.
(On delivery of new vehicle, the reservoir
is filled to the MIN level. Be sure to
replenish approximately 3/8 US quart
(0.3 to 0.4 liter) of coolant.)
NOTICE
Do not overfill the coolant. This may
increase the pressure in the cooling
system and cause coolant leaks.
To maximize vehicle performance, the
coolant mixture ratio should be a combi-
nation of 30% coolant antifreeze and 70%
demineralized or distilled water for max-
imum cooling system performance re-
gardless of ambient temperatures.
If ambient temperatures are anticipated
below 5°F (−15°C), make sure a proper
mixture ratio of 50% antifreeze and 50%
demineralized or distilled water mix is
used.Engine and powertrainThe information and specifications in
this section apply only when engaging in performance driving.
.
Check the engine, transmission, differ-
ential and under the vehicle for oil and
coolant leaks.
. Inspect the areas surrounding of the
catalytic converter for heat deteriora-
tion.
. Always perform the transmission
setting. After that, adjust the clutch
clearance so that the clearance is less
than the clearance used for daily
driving. Your GT-R certified NISSAN
dealer has the necessary information
and equipment to set the clutch
clearance to the correct specification.
The clearance used for daily driving
increases clutch heat generated dur-
ing Performance Driving. This leads to
an increase in temperature of the
transmission oil. In addition, a more
direct shifting feel can be obtained by
reducing the clutch clearance for
Performance Driving. The clutch clear-
ance should be reset to the daily
driving specification after Perfor-
mance Driving. It is recommended
you see a GT-R certified NISSAN dealer
for information.
NOTICE
Failure to have the clutch properly
adjusted before performance driving
may cause the transmission oil tem-
perature to increase which may
cause transmission damage.
. Inspect and confirm the clearance
between the exhaust finisher and rear
bumper is more than 0.24 in (6 mm)
(up/down) and more than 0.20 in (5
mm) (left/right).
. Inspect the dust boot of the drive
shaft universal joint for cracks or
damage.Suspension and wheel alignmentThe information and specifications in
this section apply only when engaging
in performance driving.
.Check the steering and suspension
system and other links for loose and/
or damaged parts.
. Measure and adjust the wheel align-
ment. (
“Wheel alignment” page
GTR-10) It is recommended you con-
tact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the
recommended setting for high perfor-

Engine oil pressure warning
light
This light warns of low engine oil pres-
sure. If the light flickers or comes on
during normal driving, pull off the road in
a safe area and stop the engine immedi-
ately. It is recommended you call a GT-R
certified NISSAN dealer.
The engine oil pressure warning light is
not designed to indicate a low oil level.
Check the vehicle information display or
use the dipstick to check the oil level.
(
“Engine oil level display” page 2-13)
(“Checking engine oil level” page 8-9)
NOTICE
Running the engine with the engine
oil pressure warning light on could
cause serious damage to the engine
almost immediately. Turn off the
engine as soon as it is safe to do so.
Seat belt warning light and
chime
The light and chime remind you to fasten
seat belts. The light illuminates whenever
the ignition switch is placed in the ON
position, and will remain illuminated until
the driver’s seat belt is fastened. At the
same time, the chime will sound for about
6 seconds unless the driver’s seat belt is
securely fastened.
The seat belt warning light for the front
passenger will illuminate if the seat belt is
not fastened when the front passenger’s
seat is occupied. For approximately 5
seconds after the ignition switch is placed
in the ON position, the system does not
activate the warning light for the front
passenger. (
