VEHICLE DYNAMIC CONTROL (VDC)
OFF MODEMake sure VDC is on before driving the vehicle.
The VDC OFF mode should only be used to help
free a vehicle stuck in mud or snow by
temporarily stopping VDC operation and keep-
ing torque on wheels.SUMMER TIRESThe GT-R summer tires are made from a
specially formulated rubber to maximize the
vehicle’s performance capabilities. Performance
of summer tires is substantially reduced when
temperatures are less than 328F(0 8C) so you
must drive carefully. NISSAN recommends the
use of winter or all-season tires on all four
wheels if you plan to operate your vehicle in
snowy or icy conditions when temperatures are
less than 32 8F(0 8C) .
WARNING
Never use summer tires when the
temperature is below 48 F( 20 8C) to
prevent permanent tread deformation
which may cause tire damage or tire
failure. This may cause a loss of vehicle
control which can result in serious
personal injury or death.
ALL-SEASON TIRESDo not exceed the speed rating of the tire that is
installed on the vehicle.
The body of the GT-R has been manufactured
on special fixtures utilizing a hybrid structure
with aluminum die cast parts for the frame work.
Special skills, information and equipment are
required to correctly repair the body. Contact a
GT-R certified NISSAN dealer if the vehicle is
damaged, such as in a collision, and they will
recommend an appropriate body shop.
Only certified body shops using CELETTE
®
advanced collision repair equipment are ap-
proved by NISSAN for repairing structural body
damage. Contact a GT-R certified NISSAN
dealer or NISSAN Consumer Affairs for a
referral or list of certified body shops.

NISSAN dealer as soon as possible.
. The power train may be damaged if
you continue driving with the warn-
ing light blinking rapidly.
TIGHT CORNER BRAKING PHE-
NOMENONWhen driving on dry pavement in AWD mode, or
immediately after starting the engine in cold
conditions, when the steering wheel is turned all
the way, the vehicle may behave as if the brakes
had been applied. This phenomenon is known
as the “tight corner braking phenomenon”.
This phenomenon is unique to AWD vehicles,
and occurs due to a difference in speeds
between the front and rear wheels while the
vehicle is turning. This does not indicate that
there is a malfunction. If this phenomenon
occurs, more force will be required to operate
the steering wheel.NOTE:.If the tight corner braking phenomenon
occurs, a slipping sound may be heard
from the tires, or a squeaking sound
may be heard from the drive system.
. If excessive operation continues when
a wheel has come off the road or at
other times when the operation causes a large difference in speed between the
front and rear wheels (the wheels are
spinning) , the oil temperature in the
drive system parts will increase.
In this case, to protect the drive system
parts, the AWD warning light blinks
rapidly and the system switches to
RWD mode or low AWD mode. Keep
the vehicle stopped and idling for a
short time. When the warning light
stops blinking, the vehicle returns from
RWD mode to normal driving mode.
. If you feel an unusual vibration in the
vehicle, even if the warning lights are
not illuminated, have the vehicle in-
spected by a GT-R certified NISSAN
dealer.
TIRESThis vehicle is equipped with special tires. When
changing the tires, install the designated special
tires. Replacing tires as a set of four with new
ones is recommended. However, if a tire is
punctured or damaged, it may be possible to
replace only the damaged tire. Determining
whether one tire or a complete set of tires
should be replaced is based on a number of
factors including tire wear and condition. Con-
tact your GT-R certified NISSAN dealer. They
can recommend if an individual tire or a complete set should be replaced.
NOTICE
If tires other than the designated tires,
tires with large differences in wear or
tires of different sizes are installed, the
AWD performance will be degraded and
the drive mechanism may be damaged.AWD SYSTEM CHARACTERISTICSThe AWD system automatically distributes the
optimal torque to the front and rear wheels. This
provides both the superior turning performance
of a front wheel drive vehicle and the traction of
a AWD vehicle.
Electronic control continuously distributes tor-
que to the front and rear wheels in the range
from 0:100 (rear-wheel drive mode) to 50:50
(all-wheel drive mode) to match the driving
conditions and road conditions. This allows the
engine output (torque) to be effectively trans-
mitted to the road surface.

This vehicle is equipped with a 1.5-way me-
chanical Limited Slip Differential (LSD) .
WARNING
Sudden operation of the accelerator
pedal can result in fishtailing or side-
slip, possibly causing an accident. Use
particular caution when driving in rainy
weather or on slippery roads.
NOTICE
Use the designated differential gear oil.
If any oil other than the designated oil
is used, the LSD may not operate
correctly, and noise and vibration may
occur, possibly resulting in a malfunc-
tion.NOTE:.If the vehicle accelerates from a stop
with the steering wheel turned in cold
temperatures, the inner wheel tire may
slip and some noise or vibration may
be heard. This phenomenon is unique
to vehicles equipped with the LSD. This
does not indicate that there is a mal-
function.
. The LSD controls the speed difference between the left and right wheels, and
optimally allocates torque to the
wheels.
. The 1.5-way mechanical LSD in this
vehicle is characterized by its asymme-
trical LSD effects when the accelerator
pedal is ON and when it is OFF. This
allows the appropriate amount of tor-
que for the driving environment to be
transmitted to the road surface.5-36

. If engine related parts such as
muffler are not standard equipment
or are extremely deteriorated, the
indicator or
indicator or
both indicator lights may illuminate.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars and bushings are
not NISSAN approved or are extre-
mely deteriorated the VDC system
may not operate properly. This could
adversely affect vehicle handling
performance, and the
indicator
or
indicator or both indicator
lights may illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extre-
mely deteriorated, the
indicator
or
indicator or both indicator
lights may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the
in-
dicator or
indicator or both indicator lights may illuminate. Do
not drive on these types of roads.
. When driving on unstable surfaces
such as a turntable, ferry, elevator
or ramp, the
indicator or
indicator or both indicator lights
may illuminate. This does not indi-
cate that there is a malfunction.
Restart the engine after driving onto
a stable surface.
. If wheels or tires other than those
recommended are used, the VDC
system may not operate properly
and the
indicator or
in-
dicator or both indicator lights may
illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
NOTE:.Make sure VDC is on before driving the
vehicle. The VDC OFF mode is an
emergency mode to help free a vehicle
stuck in mud or snow by temporarily
stopping VDC operation and keeping
torque on the wheels.
. When attempting to free the vehicle
from mud or fresh snow, the VDC will detect the tire slipping, and the engine
speed may not increase even when the
accelerator pedal is depressed. To raise
the engine speed, use the VDC set up
switch to turn the VDC system OFF.
. When the VDC system is turned OFF,
all VDC functions (including traction
control) , except for the ABS functions,
are deactivated.

8. With the wheel nut wrench, tighten wheelnuts alternately and evenly in the sequence
as illustrated (
*1,*2,*3,*4,*5) until
they are tight.
9. Lower the vehicle slowly until the tire touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence as illustrated. Lower the
vehicle completely.
WARNING
.Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident. .
Do not use oil or grease on the
wheel studs or nuts. This could
cause the nuts to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600
miles (1,000 km) .
WARNING
If the road wheels are hot, allow them
to cool sufficiently before tightening
the wheel nuts. Otherwise, the wheel
nuts cannot be tightened to specifica-
tion.NOTE:.As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.
Wheel nut tightening torque:
97 ft-lb (132 N·m)
The wheel nuts must be kept tightened
to specification at all times. It is
recommended that wheel nuts be tigh-
tened to specifications at each lubrica-
tion interval.
. Adjust tire pressure to the COLD pres-
sure. COLD pressure: After the vehicle has
been parked for three hours or more or
driven less than 1 mile (1.6 km) .
