2021 NISSAN GT-R ECU

OPENING AND CLOSING THE
TRUNKWhen opening the trunk, first unlock it
then lift up the trunk lid so that it is fully
open.
When closing the trunk, lower the trunk
lid and press it until it is securely locked in
place. The strap
(except for carbon
trunk lid models) or the handle
(for
carbon trunk lid models) can be used
when the trunk lid is dirty.
NOTICE
. Open and close the trunk without
grasping the rear spoiler. Grasp-
ing the rear spoiler to open or
close the trunk may damage the
spoiler.
. Do not leave the key inside the
trunk.
NOTE:
. To prevent the Intelligent Key from
being accidentally locked in the
trunk, lockout protection is
equipped with the Intelligent Key
system. When the trunk lid is closed
with the Intelligent Key inside the
trunk, the outside buzzer will sound and the trunk will open.
. The trunk of this vehicle is slightly
more difficult to close than an or-
dinary vehicle (particularly when the
vehicle is new). This is because the
trunk rigidity has been increased to
handle the high load on the rear
spoiler during vehicle operation.
This does not indicate that there is
a malfunction. Check that the trunk
is securely locked.
EMERGENCY TRUNK LID RELEASE
WARNING
Closely supervise children when they
are around cars to prevent them
from playing and becoming locked
in the trunk where they could be
seriously injured. Keep the car
locked, with the trunk lid securely
latched, when not in use, and pre-
vent children’s access to Intelligent
Keys.

is used.
. Objects in the RearView Monitor
will appear visually opposite
compared to when viewed in the
rearview and outside mirrors.
. Use the displayed lines as a re-
ference. The lines are highly af-
fected by the number of
occupants, fuel level, vehicle po-
sition, road conditions and road
grade.
. Make sure that the trunk lid is
securely closed when backing up.
. Do not put anything on the rear-
view camera. The rearview cam-
era is installed above the license
plate.

ft (1 m) from the door.

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

garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
. Always use tires of the specified
type, size, brand, construction
(bias, bias-belted, radial or run-
flat), and tread pattern on all four
wheels. Failure to do so may
result in a circumference differ-
ence between tires on the front
and rear axles which will cause
excessive tire wear and may da-
mage the transmission, transfer
case and differential gears.
Wheel balanceUnbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance.
Therefore, they should be balanced as
required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the rear wheels on the
vehicle could lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Informa-
tion” (US) or “Tire Safety Information” (Canada) in the Warranty Information
Booklet.

JACKING VEHICLE AND REMOVING
WHEELS
WARNING
.
Make sure the parking brake is
securely applied and the trans-
mission is shifted into the
position.
. Never change tires when the ve-
hicle is on a slope, ice or slippery
areas. This is hazardous.
. Never change tires if oncoming
traffic is close to your vehicle.
Wait for professional road assis-
tance.
Blocking wheelsPlace suitable blocks
at both the front
and back of the wheel diagonally oppo-
site the flat tire to prevent the vehicle
from moving when it is jacked up.

CAUTION
After using the tools, put them back
in their original places. An accident
may occur if you leave them in the
car unsecured.Jacking up the vehicle and re-
moving the tire
WARNING
.Never get under the vehicle while
it is supported only by the jack. If
it is necessary to work under the
vehicle, support it with safety
stands.
. Use the correct jack-up points.
Never use any other part of the
vehicle for jack support.
. Never jack up the vehicle more
than necessary.
. Never use blocks on or under the
jack.
. Do not start or run the engine
while vehicle is on the jack, as it
may cause the vehicle to move.
This is especially true for vehicles with limited slip differentials.
. Do not allow passengers to stay
in the vehicle while it is on the
jack.
Carefully read the caution label at-
tached to the jack body and the follow-
ing instructions.

accident.
. Be sure the seat belt tongue is
securely fastened to the proper
buckle.
. Do not wear the seat belt inside
out or twisted. Doing so may
reduce its effectiveness.
. Do not allow more than one
person to use the same seat belt.
. Never carry more people in the
vehicle than there are seat belts.
. If the seat belt warning light
glows continuously while the
ignition is turned ON with all
doors closed and all seat belts
fastened, it may indicate a mal-
function in the system. It is re-
commended you have the system
checked by a GT-R certified
NISSAN dealer.
. No changes should be made to
the seat belt system. For exam-
ple, do not modify the seat belt,
add material, or install devices
that may change the seat belt
routing or tension. Doing so may
affect the operation of the seat
belt system. Modifying or tam-
pering with the seat belt system
may result in serious personal injury.
. Once a seat belt pretensioner has
activated, it cannot be reused and
must be replaced together with
the retractor. It is recommended
you see a GT-R certified NISSAN
dealer.
. Removal and installation of the
pretensioner system components
should be done by a GT-R certi-
fied NISSAN dealer.
. All seat belt assemblies, including
retractors and attaching hard-
ware, should be inspected after
any collision by a GT-R certified
NISSAN dealer. NISSAN recom-
mends that all seat belt assem-
blies in use during a collision be
replaced unless the collision was
minor and the belts show no
damage and continue to operate
properly. Seat belt assemblies
not in use during a collision
should also be inspected and
replaced if either damage or im-
proper operation is noted.
. All child restraints and attaching
hardware should be inspected
after any collision. Always follow
the restraint manufacturer’s in- spection instructions and repla-
cement recommendations. The
child restraints should be re-
placed if they are damaged.

The ELR locks the seat belt when the
vehicle slows down rapidly or during
impacts.
The Automatic Locking Retractor (ALR)
mode or child restraint mode locks the
seat belt for child restraint installation.
When the ALR mode is activated the seat
belt cannot be extended again until the
seat belt tongue is detached from the
buckle and fully retracted. The seat belt
returns to the ELR mode after the seat
belt is fully retracted.

status light” page 1-42)
WARNING
When fastening the seat belts, be
certain that seatbacks are comple-
tely secured in the latched position.
If they are not completely secured,
passengers may be injured in an
accident or sudden stop.
Unfastening the seat beltsTo unfasten the seat belt, push the
button on the buckle. The seat belt
automatically retracts.
Checking seat belt operationSeat belt retractors are designed to lock
seat belt movement by two separate
methods:
. When the belt is pulled quickly from
the retractor.
. When the vehicle slows down rapidly.
To increase your confidence in the seat
belts, check the operation as follows:
. Grasp the shoulder belt and pull for-
ward quickly. The retractor should
lock and restrict further belt move-
ment.
If the retractor does not lock during this
check or if you have any question about
seat belt operation, see a GT-R certified
NISSAN dealer.
