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

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

. If the oil level is below
,
remove the oil filler cap and pour
recommended oil through the open- ing.
Do not overfill
.
6. Recheck oil level with the dipstick.
NOTE:
. It is normal to add some oil between
oil maintenance intervals or during
the break-in period, depending on
the severity of operating conditions.
More engine oil is consumed by
frequent acceleration/deceleration
especially when the engine rpm is
high. If your rate of oil consumption
increases suddenly or without ex-
planation, NISSAN recommends that
you have your vehicle inspected by a
GT-R certified NISSAN dealer.
. When the vehicle is delivered, the
engine oil is set to 0.39 in (10 mm)
below the H mark for optimal high
performance driving. The engine oil
can be filled up to the H mark if
performance driving is not engaged.

NOTICE
It is recommended that you only use
the following specified fluids and
parts in the GT-R to avoid possible
vehicle damage.ENGINE OILMobil 1 (0W-40) (100% synthetic oil) or
equivalent
Mobil 1 (0W-40) (100% synthetic) is the
factory fill oil. The VR38 engine with its
plasma-sprayed bores was developed
using this oil. NISSAN cannot ensure
proper engine operation and durability if
other non-equivalent synthetic oil is used.
If Mobil 1 (0W-40) or equivalent is not
available, Mobil 1 (10W-40) (100% syn-
thetic) or equivalent may be used; how-
ever, some performance loss may be
noticed.
Furthermore, replacement of the engine
oil with MOTUL NISMO COMPETITION OIL
type 2193E(5W40) is recommended for
the frequent high performance driving
opportunities.
NISSAN cannot ensure proper engine
operation and durability if other non-
equivalent synthetic oil is used.The use of additives, chemical materials
or abrasive compounds is prohibited.
The use of additives, chemical materials,
abrasive compounds or other high per-
formance engine oils may cause internal
engine damage.

. Transmission oil temperature is 284°F
(140°C) or higher:
If the transmission oil temperature
increases to over 284°F (140°C), the
color of the meter display changes to
red. However, the vehicle can continue
to be driven until the temperature
reaches 295°F (146°C). If the oil tem-
perature exceeds 284°F (140°C) while
driving (the color of the meter dis-
played in red), change both the trans-
mission oil and the differential oil after
driving because these fluids have
deteriorated because of the heat.

ADDITIONAL MAINTENANCE ITEMS

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
