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

R MODE START FUNCTION

Do not use the cruise control when
driving under the following condi-
tions. Doing so could cause a loss of
vehicle control and result in an acci-
dent.
.When it is not possible to keep
the vehicle at a set speed.
. In heavy traffic or in traffic that
varies in speed.
. On winding or hilly roads.
. On slippery roads (rain, snow, ice,
etc.).
. In very windy areas.
NOTE:
. When the SAVE mode is selected
with the transmission setup switch,
the acceleration and deceleration
can be controlled smoothly. When
the SAVE mode is selected, the
maximum setting speed is lower
than the one in the normal mode. When the vehicle approaches a gen-
tle uphill, there may be a slight delay
as the vehicle returns to the preset
speed. However, the vehicle will
gradually accelerate and return to
the preset speed.
PRECAUTIONS ON CRUISE CON-
TROL.
If the cruise control system malfunc-
tions, it will cancel automatically. The
SET indicator will blink and the cruise
control system warning will appear to
warn the driver. (
“Cruise control
system warning” page 2-43)
. If the engine coolant temperature
becomes excessively high, the cruise
control system will be canceled auto-
matically.
. If the SET indicator blinks, turn the
cruise control main switch off and it is
recommended you contact a GT-R

CRUISE CONTROL

NOTICE
When the vehicle is stopped on a hill,
do not hold the vehicle in place by
depressing the accelerator pedal.
Doing so may cause the clutch to
overheat and result in transmission
damage. Use the brakes to prevent
the vehicle from moving.
The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the
brake pedal and apply the accelerator
when the vehicle is stopped on a hill.
Hill start assist will operate automatically
under the following conditions:
. The shift lever is moved to a forward
or reverse position.
. The vehicle is stopped completely on a
hill by applying the brake.
The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to
roll back and hill start assist will stop operating completely.
Hill start assist will not operate when the
shift lever is moved to the
or
position
or on a flat and level road.
NOTE:
This system does not function when the
Vehicle Dynamic Control VDC) system
warning appears on the vehicle infor-
mation display located in the tach-
ometer. (

is started.
If any malfunction occurs in the AWD
system while the engine is running, the
warning light will come on.
The warning light may blink rapidly
(about twice per second) while trying to
free a stuck vehicle due to high AWD
clutch temperature. The driving mode
may change to two-wheel drive. If the
warning light blinks rapidly during opera-
tion, stop the vehicle with the engine
idling in a safe place immediately. Then if
the light goes off after a while, you can
continue driving.
A large difference between the diameters
of front and rear wheels will make the
warning light blink slowly (about once per
two seconds). Pull off the road in a safe
area, and idle the engine. Check that all
tire sizes are the same, tire pressure is
correct and tires are not worn and winter
tires are not installed on the front or rear
wheels only.
If the warning light is blinking after the
above operation, it is recommended you
have your vehicle checked by a GT-R
certified NISSAN dealer as soon as possi-
ble.
If non-genuine GT-R tires are used, the
warning light may illuminate. (

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.
GASOLINE SMELLThe fuel temperature is higher when the
vehicle is hot. This may cause a gasoline
smell from the vehicle. This does not
indicate that there is a malfunction. The
smell will go away when the fuel tem-
perature has cooled.OUTSIDE TEMPERATURE DISPLAY
INDICATES HIGHER TEMPERATUREHeat from the engine compartment, ra-
diator and intercoolers can affect the
outside temperature display. The outside
temperature display may indicate a high-
er than actual temperature while driving
or stopped. This is normal.IDLE SPEED IS NOT STEADYThe idle speed may not be steady when
the engine compartment is extremely
hot. This is normal. The engine speed will
be steady when the engine cools down.
In this case, the Malfunction Indicator
Light (MIL) may come on. After a few
driving trips, the MIL should turn off. If the
light remains on after a few driving trips, it
is recommended you have the vehicle
inspected by a GT-R certified NISSAN
dealer.

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 touch screen
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 warning light”
page 2-30) (
“Tire Pressure Monitoring
System (TPMS)” page 5-4) (
“Flat tire”
page 6-3)
Tire inflation pressure
Check the tire pressure often and
always prior to long distance trips.
The recommended 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
Pressure” heading. The Tire and
Loading Information label is affixed
to the driver side door end. Tire
pressures should be checked reg-
ularly 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 touch screen dis-
play. See the separate Multi Func-
tion 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. It is recommended you
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.
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
under inflation, may adversely
affect tire life and vehicle hand-
ling.
WARNING
.
Improperly inflated tires can
fail suddenly and cause an
accident.
