warning light NISSAN GT-R 2021 Workshop Manual

ways use run-flat tires of the specified
size on all four wheels. Mixing tire sizes or
construction may reduce vehicle handling
stability. If necessary, contact a GT-R
certified NISSAN dealer for assistance.
Frequently check the tire pressure infor-
mation on the touch screen display and
adjust pressure of each tire properly. See
the separate Multi Function Display Own-
er’s Manual.
It can be difficult to tell if a run-flat tire is
under-inflated or flat. Check the tire
pressures as described earlier in this
section. If the tire becomes under-inflated
while driving, the low tire pressure warn-
ing light will come on. If the tire becomes
flat while driving, the low tire pressure
warning light and the run-flat tire warn-
ing display will come on.
Low tire pressure:
NOTICE
.Never install tire chains on a
punctured run-flat tire, as this
could damage your vehicle.
. Avoid driving over any projection
or pothole, as the clearance be-
tween the vehicle and the ground
is smaller than normal.
. Do not enter an automated car
wash with a punctured run-flat
tire.
. It is recommended you have the
punctured tire replaced by a GT-R
certified NISSAN dealer as soon

being uninstalled from the
wheels, use equipment such as a
leverless automatic tire changer.
It is only possible to reuse the
tires when they have no cracks
and/or deformations on the bead
portion. However, if you use a
lever-type tire changer, cracks
and deformation may occur on
the bead portion of the tires
meaning that the tires cannot be
reused.
. 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.
WARNING
.The use of tires other than those
specified or the mixed use of tires
of different brands, construction
(bias, bias-belted, radial or run-
flat), or tread patterns can ad-
versely affect the ride, braking,
VDC system, handling, ground
clearance, body-to-tire clearance, tire chain clearance, speed-
ometer calibration, headlight
aim and bumper height. Some of
these effects may lead to acci-
dents and could result in serious
personal injury.
. If the wheels are changed for any
reason, always replace with
wheels which have the same off-
set dimension. Wheels of a differ-
ent off-set could cause prema-
ture tire wear, degrade vehicle
handling characteristics, affect
the VDC system and/or cause
interference with the brake discs.
Such interference can lead to
decreased braking efficiency
and/or early brake pad wear.
(
“Wheels and tires” page 10-
10)
. When a wheel is replaced, tire
pressure will not be indicated,
the TPMS will not function and
the low tire pressure warning
light will flash for approximately
1 minute and remain on after the
1 minute. It is recommended you
contact a GT-R certified NISSAN
dealer as soon as possible for tire
replacement and/or system re-
setting. .
Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. The TPMS sensor may be da-
maged if it is not handled cor-
rectly. Be careful when handling
the TPMS sensor.
. When replacing the TPMS sensor,
the ID registration may be re-
quired. Contact a GT-R certified
NISSAN dealer for ID registration.
. Do not use a valve stem cap that
is not specified by NISSAN. The
valve stem cap may become
stuck.
. Be sure that the valve stem caps
are correctly fitted. Otherwise the
valve may be clogged up with dirt
and cause a malfunction or loss
of pressure.
. Do not install a damaged or
deformed wheel or tire even if it
has been repaired. Such wheels
or tires could have structural
damage and could fail without
warning.
. Never use retread tires.
. For additional information re-

of each nut lightly
contacts the seat part
of the wheel
hole.
When replacing a front wheel, make
sure the hole in the wheel is aligned
with the pin on the brake disc rotor.
8. With the wheel nut wrench, tighten wheel nuts alternately and evenly in
the sequence illustrated (
,
,
,
,
)
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.

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

deformed wheel or tire even if it
has been repaired. Such wheels
or tires could have structural
damage and could fail without
warning.
. Never use retread tires.
. For additional information re-

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

7. Check to make sure the child restraintis properly secured prior to each use. If
the child restraint is loose, repeat
steps 1 through 6.
WARNING
The three-point seat belt with Auto-
matic Locking Retractor (ALR) must
be used when installing a child re-
straint. Failure to use the ALR mode
will result in the child restraint not
being properly secured. The restraint
could tip over or be loose and cause
injury to a child in a sudden stop or
collision. Also, it can change the
operation of the front passenger air
bag. See “Front passenger air bag
and status light” later in this section.
