2021 NISSAN GT-R Owners Manual

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. (

TIGHT CORNER BRAKING PHE-
NOMENONIf the steering wheel is turned more than
half a turn when the vehicle is started
when it is cold, it may be harder to move
the vehicle forward and backward. 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 malfunc-
tion.
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.Reducing tight corner braking
phenomenonThe tight corner braking phenomenon
can be reduced if the following three
conditions are met:
.Transmission setup switch is set to
Normal mode.
. Vehicle speed is low (less than ap-
proximately 6 MPH (10 km/h)). .
The steering wheel is turned more
than 1/2 turn.
TIRESThis vehicle is equipped with special tires.
When changing the tires, install the de-
signated special tires. Replacing tires as a
set of four with new ones is recom-
mended. 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. Contact 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 mechan-
ism may be damaged.
AWD SYSTEM CHARACTERISTICSThe AWD system automatically distri-
butes the optimal torque to the front
and rear wheels. This provides both the
superior turning performance of a rear
wheel drive vehicle and the traction of a
AWD vehicle.
Electronic control continuously distri-
butes torque 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 transmitted to
the road surface.

3. Loosen each wheel nut one or two turns by turning counterclockwise
with the wheel nut wrench. Do not
remove the wheel nuts until the tire
is off the ground.

When replacing a front wheel, make
sure the hole in the wheel is aligned

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 comple-
tely.
WARNING
If the road wheels are hot, allow
them to cool sufficiently before tigh-
tening the wheel nuts. Otherwise, the
wheel nuts cannot be tightened to
specification.
NOTE:.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
