wheel torque NISSAN GT-R 2015 R35 Owners Manual

GTR-10GT-R Overview
.Drive with the suspension setup swit�fh in
the COM�b mode to allow more suspension
stroke.
600 to 1,200 miles (1,000 to 2,000 km):
. Drive with the engine speed kept relatively
high with the shift lever in the
&Mposition.
Shifting is re�fommended between 1st and
4th gears.
. Avoid unne�fessary qui�fk steering and
abrupt braking.
. Drive with the suspension setup swit�fh in
the COM�b mode to allow more suspension
stroke.
Even though the mileage rea�fhes over 1,200
miles (2,000 km) , the �flut�fh may take longer to
properly engage if the vehi�fle is mainly driven in
town at a low speed. NISSAN re�fommends
breaking in the �flut�fh at a GT-R �fertified
NISSAN dealer. Always perform the transmis-
sion setting after breaking in the �flut�fh. If the
transmission setting is not �fomplete, ex�fessive
loads may be applied to the transmission and
power train system parts during starting and
shifting, whi�fh may result in a malfun�ftion or
damage.
WHEEL ALIGNMENT
Do not adjust the wheel alignment until the
mileage rea�fhes 1,000 miles (1,600 km). Until
then, the suspension may not engage enough
and the height may be higher.
However, make sure to adjust the alignment
after 1,000 miles (1,600 km) .
The wheel alignment �fan be adjusted by a GT-R
�fertified NISSAN dealer in a�f�fordan�fe with
spe�fifi�fations for �fity driving to high perfor-
man�fe driving.
The tires on the GT-R may have different wear
rates and wear patterns in �fomparison to
�fonventional passenger vehi�fles. Conta�ft a
GT-R �fertified NISSAN dealer to �fonfirm that
the alignment is within spe�fifi�fations.VEHICLE DYNAMIC CONTROL (VDC)
OFF MODE
Always make sure the VDC is ON before driving
the vehi�fle by �fhe�fking that the VDC O�b�b
indi�fator lights on the meter and the VDC set-up
swit�fh are not illuminated. The GT-R is a high
performan�fe vehi�fle and the VDC must be on/
a�ftivated to provide proper powertrain operation
and intended drivability.
WARNING
. The VDC OFF mode should ONLY be
used briefly to help free the vehicle
if stuck in snow or mud by tempora-
rily stopping operation of the VDC
to maintain wheel torque.
. Driving the GT-R with the VDC off
may lead to handling issues related
to steering maneuvers, acceleration,
or deceleration. Moreover, driving
with the VDC off can result in an
inoperative vehicle by causing ser-
ious damage to the powertrain,
including damage to the Transaxle
Assembly including Transfer, Clutch,
Gears, Transaxle case and all of its
components and other drivetrain

Normal (lig�ft is off)
.T�fis mode is for use in a broad range of driving conditions�b for routine driving during
fair to rainy weat�fer�b as well as for driving on road surfaces t�fat are slippery due to
snow or ice.
Make sure to use t�fis mode for everyday driving.
.Temporary mode t�fat can be used to free if it is stuck in snow or mud
(Wit�f t�fe transmission switc�f in SAVE mode�b freeing t�fe ve�ficle become easier.)
NOTE:
Always make sure the VDC is ON before driving the vehicle by checking that the VDC OFF
indicator lights on the meter and the VDC set-up switch are not illuminated. The GT-R is a
high performance vehicle and the VDC must be on/activated to provide proper powertrain
operation and intended drivability.
WARNING
. The VDC OFF mode should ONLY be
used briefly to help free the vehicle
if stuck in snow or mud by tempora-
rily stopping operation of the VDC
to maintain wheel torque.
. Driving the GT-R with the VDC off
may lead to handling issues related
to steering maneuvers, acceleration,
or deceleration. Moreover, driving
with the VDC off can result in an
inoperative vehicle by causing ser-
ious damage to the powertrain,
including damage to the Transaxle
Assembly including Transfer, Clutch,
Gears, Transaxle case and all of its
components and other drivetrain
component(s) by overheating or ex-
cessive force.
. Damage to the powertrain or any
drivetrain component(s) that occurs
when there is a record in the Vehicle
Status Data Recorder (VSDR) that
the vehicle was driven with VDC off
during the period when the damage
was incurred is excluded from war-
ranty coverage.

The rear final drive of this vehicle is equipped
with a \f.5-wa\b mechanical Limited Slip Differ-
ential (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 the rear
final drive of this vehicle is character-
ized by its asymmetrical LSD effects
when the accelerator pedal is ON and
when it is OFF. This allows the appro-
priate amount of torque for the driving
environment to be transmitted to the
road surface.

LIMITED SLIP DIFFERENTIAL (LSD)

shock absorbers, struts, springs,
stabilizer bars, bushings and
wheels are not NISSAN approved
or are extremely deteriorated, the
VDC system may not operate prop-
erly. This could adversely affect
vehicle handling performance, and
the VDC warning light
may
illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are
not standard equipment or are ex-
tremely deteriorated, the VDC warn-
ing light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the VDC warn-
ing light
may illuminate. Do not
drive on these types of roads.
. When driving on an unstable sur-
face such as a turntable, ferry, elevator or ramp, the VDC warning
light
may illuminate. This is not
a malfunction. Restart the engine
after driving onto a stable surface.
. If wheels or tires other than the
those recommended are used, the
VDC system may not operate prop-
erly and the VDC warning light
may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
NOTE:
. Always make sure the VDC is ON
before driving the vehicle by checking
that the VDC OFF indicator lights on
the meter and the VDC set-up switch
are not illuminated.
The GT-R is a high performance vehicle
and the VDC must be on/activated to
provide proper powertrain operation
and intended drivability.

8. With the wheel nut wrench, tighten wheelnuts alternatel\f and evenl\f in the sequence
as illustrated \b
*1,*2,*3,*4,*5) until
the\f are tight.
9. Lower the vehicle slowl\f until the tire touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securel\f
in the sequence as illustrated. Lower the
vehicle completel\f.
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:
Except for NISMO models 97 ft-lb (132 N·m)
NISMO models 114 ft-lb (155 N·m)
The wheel nuts must be kept tigh-
tened to specification at all times. It
is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD
pressure.
COLD pressure: After the vehicle has
been parked for three hours or more
or driven less than 1 mile (1.6 km) .
COLD tire pressures are shown on
the Tire and Loading Information
label affixed to the driver’s door
opening.
