(“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. (

the equipment.

OPENING AND CLOSING THE
TRUNKWhen opening the trunk, first unlock it
then lift up the trunk lid so that it is fully
open.
When closing the trunk, lower the trunk
lid and press it until it is securely locked in
place. The strap
(except for carbon
trunk lid models) or the handle
(for
carbon trunk lid models) can be used
when the trunk lid is dirty.
NOTICE
. Open and close the trunk without
grasping the rear spoiler. Grasp-
ing the rear spoiler to open or
close the trunk may damage the
spoiler.
. Do not leave the key inside the
trunk.
NOTE:
. To prevent the Intelligent Key from
being accidentally locked in the
trunk, lockout protection is
equipped with the Intelligent Key
system. When the trunk lid is closed
with the Intelligent Key inside the
trunk, the outside buzzer will sound and the trunk will open.
. The trunk of this vehicle is slightly
more difficult to close than an or-
dinary vehicle (particularly when the
vehicle is new). This is because the
trunk rigidity has been increased to
handle the high load on the rear
spoiler during vehicle operation.
This does not indicate that there is
a malfunction. Check that the trunk
is securely locked.
EMERGENCY TRUNK LID RELEASE
WARNING
Closely supervise children when they
are around cars to prevent them
from playing and becoming locked
in the trunk where they could be
seriously injured. Keep the car
locked, with the trunk lid securely
latched, when not in use, and pre-
vent children’s access to Intelligent
Keys.
The emergency trunk lid release mechan-

is used.
. Objects in the RearView Monitor
will appear visually opposite
compared to when viewed in the
rearview and outside mirrors.
. Use the displayed lines as a re-
ference. The lines are highly af-
fected by the number of
occupants, fuel level, vehicle po-
sition, road conditions and road
grade.
. Make sure that the trunk lid is
securely closed when backing up.
. Do not put anything on the rear-
view camera. The rearview cam-
era is installed above the license
plate.
. When washing the vehicle with
high-pressure water, be sure not
to spray it around the camera.
Otherwise, water may enter the
camera unit causing water con-
densation on the lens, a malfunc-
tion, fire or an electric shock.
. Do not strike the camera. It is a
precision instrument. Otherwise,
it may malfunction or cause da-
mage resulting in a fire or an
electric shock. The following are operating limitations
and do not represent a system malfunc-
tion:
.
When the temperature is extremely
high or low, the screen may not clearly
display objects.
. When strong light is directly coming
on the camera, objects may not be
displayed clearly.
. Vertical lines may be seen in objects
on the screen. This is due to strong
reflected light from the bumper.
. The screen may flicker under fluores-
cent light.
. The colors of objects on the RearView
Monitor may differ somewhat from
the actual color of objects.
. Objects on the monitor may not be
clear in a dark environment.
. There may be a delay when switching
to the RearView Monitor screen.
. If dirt, rain or snow accumulates on
the camera, the RearView Monitor
may not display objects clearly. Clean
the camera.
. Do not use wax on the camera win-
dow. Wipe off any wax with a clean
cloth dampened with mild detergent
diluted with water.
SYSTEM MAINTENANCE
CAUTION
.Do not use alcohol, benzine or
thinner to clean the camera. This
will cause discoloration. To clean
the camera, wipe with a cloth
dampened with diluted mild
cleaning agent and then wipe
with a dry cloth.
. Do not damage the camera as the
monitor screen may be adversely
affected.

NOTICE
.When the temperature of the
engine coolant and transmission
oil is high or low, the function
cannot be used. The temperature
range in which the R mode start
function can be used:
— Engine coolant: 140°F - 212°F
(60°C - 100°C)
— Transmission oil: 140°F - 266°F (60°C - 130°C)
. If the R mode start function is
used 4 times consecutively, the
function may be disabled and
cannot be turned on to protect
the vehicle system. While the function is disabled, the warning
light illuminates. When the warn-
ing light illuminates, perform cool
down driving. (
“Cool down”
page GTR-14) When the warning
light turns off, the function can be
used again.
. The performance of start may
vary depending on the amount
of wheel spin ,or increase and
decrease of the engine output in
response to the outside tempera-
ture. (This vehicle was set up
according to the road surface
conditions of the straight sec-
tions of the Sendai Highland Ra-
ceway course in Japan at 59°F
(15°C).)
. For safety reasons, VDC control
may activate automatically when
driving on a slippery road surface,
such as a wet road, in order to
apply the brakes or limit the
engine output.
. Frequent use of the R mode start
function increases the load on
the powertrain related parts such
as the clutch and transmission
compared to normal driving. In
particular, the clutch will wear out

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.
