2014 NISSAN GT-R ECU

GTR-18GT-R Overview
WARNING
Keep your tires inflated to the correct
tire pressure. Driving with low tire
pressure can damage some powertrain
systems and affect the operation of the
ABS and VDC systems. Low Tire pres-
sure may also cause tire failure and
result in serious personal injury or
death.
. 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.
. Make sure the wheel nuts are tight.
(
“Wheels and tires” page 8-32)
. Make sure the drive shaft nuts are tight.
. Make sure to replace the grommet seal, the
valve core and the valve cap of the Tire
Pressure Monitoring System (TPMS) sensor
attached to the wheel every 3 years for
performance driving use. Replace them
every 5 years even when not engaging in
performance driving. A dirty grommet seal
will cause the air leak from the tire. .
Make sure that the nuts and valves that are
attached to the TPMS sensor are tight and
there is no nitrogen leak.
. Use only a NISSAN genuine valve cap or
equivalent.
. Check wheel hub run out and that the wheel
rotates smoothly without any friction. Check
these with the tires removed whenever an
inspection is performed with the vehicle
jacked up.
. Secure road wheel balance weights with
aluminum tape.
. Check that the wheel nuts are not stripped.
.Make sure the tire has not slipped on the
wheel causing the assembly to be out of
balance. The reference marks on the tire and
wheel should be aligned. If the reference
marks are not aligned, the tire has slipped on
the wheel. Have the wheels/tires reba-
lanced. Make sure the old reference marks
are erased and new reference marks are
applied to the wheel and tire. When instal-
ling new tires on the wheels, make sure new
reference marks are applied to the wheels
and tires.
. Avoid the driving conditions listed under
“Additional maintenance items” in this sec-
tion for 48 hours after tires are installed on

1-2Safety — Seats, seat belts and supplemental restraint system
WARNING
.Do not ride in a moving vehicle
when the seatback is reclined. This
can be dangerous. The shoulder belt
will not be against your body. In an
accident, you could be thrown into it
and receive neck or other serious
injuries. You could also slide under
the lap belt and receive serious
internal injuries.
. For the most effective protection
when the vehicle is in motion, the
seat should be upright. Always sit well back in the seat with both feet
on the floor and adjust the seat
properly. (“Precautions on seat
belt usage” page 1-7)
. After adjustment, gently rock in the
seat to make sure it is securely
locked.
. Do not leave children unattended
inside the vehicle. They could un-
knowingly activate switches or con-
trols. Unattended children could
become involved in serious acci-
dents. .
The seatback should not be reclined
any more than needed for comfort.
Seat belts are most effective when
the passenger sits with their back
straight up and contacting the seat.
If the seatback is reclined, the risk
of sliding under the lap belt and
being injured is increased.
CAUTION
When adjusting the seat positions, be
sure not to contact any moving parts to
avoid possible injuries or damage.
NOTICE
Make sure the front seatback does not
contact the rear seat (models with rear
seat) when reclining the seat. When the
front seat is reclined to the rearmost
position, it may contact the rear seat.
This may cause an indentation in the
seatback.
SEATS

1-8Safety — Seats, seat belts and supplemental restraint system
WARNING
.Every person who drives or rides in
this vehicle should use a seat belt at
all times. Children should be prop-
erly restrained in the rear seat
(models with rear seat) and, if
appropriate, in a child restraint.
. The seat belt should be properly
adjusted to a snug fit. Failure to do
so may reduce the effectiveness of
the entire restraint system and in-
crease the chance or severity of
injury in an accident. Serious injury
or death can occur if the seat belt is
not worn properly.
. Always route the shoulder belt over
your shoulder and across your
chest. Never put the belt behind
your back, under your arm or across
your neck. The belt should be away
from your face and neck, but not
falling off your shoulder.
. Position the lap belt as low and
snug as possible AROUND THE
HIPS, NOT THE WAIST. A lap belt
worn too high could increase the
risk of internal injuries in an acci- dent.
. 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 in-
dicate a malfunction in the system.
Have the system checked by a GT-R
certified NISSAN dealer.
. No changes should be made to the
seat belt system. For example, do
not modify the seat belt, add mate-
rial, 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 tampering 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. See a GT-R certified
NISSAN dealer.
. Removal and installation of the
pretensioner system components
should be done by a GT-R certified
NISSAN dealer.
. All seat belt assemblies, including
retractors and attaching hardware,
should be inspected after any colli-
sion by a GT-R certified NISSAN
dealer. NISSAN recommends that
all seat belt assemblies in use
during a collision be replaced un-
less 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 improper operation is
noted.
. All child restraints and attaching
hardware should be inspected after

3. Position the lap belt portionlow and snug
on the hips as shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack. Be sure the
shoulder belt is routed over your shoulder
and across your chest.
The three-point type seat belts for the front
passenger and rear seats (models with rear
seat) have two modes of operation:
. Emergency Locking Retractor (ELR)
. Automatic Locking Retractor (ALR)
The Emergency Locking Retractor (ELR) mode
allows the seat belt to extend and retract to
allow the driver and passengers some freedom of movement in the seat. 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.
(
“Child restraints” page 1-15)
The ALR mode should be used only for
child restraint installation. During normal
seat belt use by an occupant, the ALR
mode should not be activated. If it is
activated it may cause uncomfortable seat
belt tension. It can also change the opera-
tion of the front passenger air bag.
(
“Front passenger air bag and status
light” page 1-41)
WARNING
When fastening the seat belts, be
certain that seatbacks are completely
secured in the latched position. If they
are not completely secured, passengers may be injured in an accident or sudden
stop.
Safety — Seats, seat belts and supplemental restraint system1-11

SEAT BELT EXTENDERS
If, because of body size or driving position, it is
not possible to properly fit the lap-shoulder belt
and fasten it, an extender that is compatible with
the installed seat belts is available that can be
purchased. The extender adds approximately 8
in (200 mm) of length and may be used for either
the driver or front passenger seating position.
See a GT-R certified NISSAN dealer for
assistance with purchasing an extender if an
extender is required.
WARNING
.Only NISSAN seat belt extenders,
made by the same company which
made the original equipment seat
belts, should be used with the
NISSAN seat belts.
. Adults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use
could result in serious personal
injury in the event of an accident.
. Never use seat belt extenders to
install child restraints. If the child
restraint is not secured properly, the
child could be seriously injured in a collision or a sudden stop.
SEAT BELT MAINTENANCE
.
To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or carpets.
Then, wipe with a cloth and allow the seat
belts to dry in the shade. Do not allow the
seat belts to retract until they are completely
dry.
. If dirt builds up in the shoulder belt
guide of the seat belt anchors, the seat
belts may retract slowly. Wipe the shoulder
belt guide with a clean, dry cloth.
. Periodically check to see that the seat
belt and the metal components such as
buckles, tongues, retractors, flexible wires
and anchors work properly. If loose parts,
deterioration, cuts or other damage on the
webbing is found, the entire seat belt
assembly should be replaced.
WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the
seat belt becomes wrapped around a
child’s neck with the ALR mode acti-
vated, the child can be seriously injured
or killed if the seat belt retracts and
becomes tight. This can occur even if
the vehicle is parked. Unbuckle the seat
belt to release the child. If the seat belt
can not be unbuckled or is already
unbuckled, release the child by cutting
the seat belt with a suitable tool (such
as a knife or scissors) to release the
seat belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is available from
many other sources, including doctors, teachers,
government traffic safety offices, and community
organizations. Every child is different, so be sure
to learn the best way to transport your child.
There are three basic types of child restraint
Safety — Seats, seat belts and supplemental restraint system1-13
CHILD SAFETY

1-14Safety — Seats, seat belts and supplemental restraint system
systems:
.Rear-facing child restraint (must not be
installed in models without rear seat)
. Forward-facing child restraint
. Booster seat
The proper restraint depends on the child’s size.
Generally, infants (up to about 1 year and less
than 20 lb (9 kg)) should be placed in rear-
facing child restraints. Forward-facing child
restraints are available for children who outgrow
rear-facing child restraints and are at least 1
year old. Booster seats are used to help position
a vehicle lap/shoulder belt on a child who can no
longer use a forward-facing child restraint.
WARNING
Infants and children need special pro-
tection. The vehicle’s seat belts may not
fit them properly. The shoulder belt may
come too close to the face or neck. The
lap belt may not fit over their small hip
bones. In an accident, an improperly
fitting seat belt could cause serious or
fatal injury. Always use appropriate
child restraints.
All U.S. states and Canadian provinces or territories require the use of approved child
restraints for infants and small children.
(
“Child restraints” page 1-15)
A child restraint may be secured in the vehicle
by using either the LATCH (Lower Anchor and
Tethers for CHildren) system (if so equipped) or
with the vehicle seat belt. (
“Child re-
straints” page 1-15)
NISSAN recommends that all pre-teens
and children be restrained in the rear seat
(models with rear seat) . According to
accident statistics, children are safer when
properly restrained in the rear seat than in
the front seat.
This is especially important because your
vehicle has a supplemental restraint sys-
tem (air bag system) for the front passen-
ger. (
“Supplemental restraint system”
page 1-34)
INFANTS
Infants up to at least one year old should be
placed in a rear-facing child restraint (models
with rear seat). NISSAN recommends that
infants be placed in child restraints that comply
with Federal Motor Vehicle Safety Standards or
Canadian Motor Vehicle Safety Standards. You
should choose a child restraint which fits your
vehicle and always follow the manufacturer’s instructions for installation and use.
SMALL CHILDREN
Children that are over 1 year old and weigh at
least 20 lb (9 kg) should remain in a rear-facing
child restraint as long as possible up to the
height or weight limit of the child restraint
(models with rear seat) . Children who outgrow
the height or weight limit of the rear-facing child
restraint and are at least 1 year old should be
secured in a forward-facing child restraint with a
harness. Refer to the manufacturer’s instructions
for minimum and maximum weight and height
recommendations. NISSAN recommends that
small children be placed in child restraints that
comply with Federal Motor Vehicle Safety
Standards or Canadian Motor Vehicle Safety
Standards. You should choose a child restraint
that fits your vehicle and always follow the
manufacturer’s instructions for installation and
use.

PRECAUTIONS ON CHILD RE-
STRAINTS
WARNING
.Failure to follow the warnings and
instructions for proper use and in-
stallation of child restraints could
result in serious injury or death of a
child or other passengers in a
sudden stop or collision:
— The child restraint must be used
and installed properly. Always
follow all of the child restraint
manufacturer’s instructions for
installation and use.
— Infants and children should never be held on anyone’s lap.
Even the strongest adult cannot
resist the forces of a collision.
— Do not put a seat belt around both a child and another pas-
senger.
— NISSAN recommends that all child restraints be installed in
the rear seat (models with rear
seat) . Studies show that chil-
dren are safer when properly restrained in the rear seat than
in the front seat. If you must
install a forward-facing child
restraint in the front seat.
(
“Forward-facing child re-
straint installation using the
seat belts” page 1-26)
— Even with the NISSAN Advanced Air Bag System, never install a
rear-facing child restraint in the
front seat. An inflating air bag
could seriously injure or kill a
child. A rear-facing child re-
straint must only be used in the
rear seat (models with rear
seat) .
— Be sure to purchase a child restraint that will fit the child
and vehicle. Some child re-
straints may not fit properly in
your vehicle.
— Child restraint anchor points are designed to withstand loads
from child restraints that are
properly fitted.
— Never use the anchor points for adult seat belts or harnesses. — A child restraint with a top tether
strap should not be used in the
front passenger seat (models
with rear seat) .
— Keep seatbacks as upright as possible after fitting the child
restraint.
— Infants and children should al- ways be placed in an appropri-
ate child restraint while in the
vehicle.
. When the child restraint is not in
use, keep it secured with the LATCH
system (if so equipped) or a seat
belt. In a sudden stop or collision,
loose objects can injure occupants
or damage the vehicle.
CAUTION
A child restraint in a closed vehicle can
become very hot. Check the seating
surface and buckles before placing a
child in the child restraint.
Models with rear seat are equipped with a
universal child restraint anchor system, referred

to as the LATCH (Lower Anchors and Tethers for
CHildren) system. Some child restraints include
rigid or webbing-mounted attachments that can
be connected to these anchors. (See
“Lower Anchors and Tethers for CHildren
System (LATCH) (models with rear seat)” page
1-17.)
If you do not have a LATCH compatible child
restraint, the vehicle seat belts can be used.
For the models without rear seat, the child
restraint is installed on the front passenger’s
seat using the seat belt and tether anchorages
(if required) . (See
“Forward-facing child
restraint installation using the seat belts” page
1-26 and
“Installing top tether strap” page
1-30.)
Several manufacturers offer child restraints for
infants and small children of various sizes. When
selecting any child restraint, keep the following
points in mind:
. Choose only a restraint with a label certifying
that it complies with Federal Motor Vehicle
Safety Standard 213 or Canadian Motor
Vehicle Safety Standard 213.
. Check the child restraint in your vehicle to
be sure it is compatible with the vehicle’s
seat and seat belt system.
. If the child restraint is compatible with your vehicle, place your child in the child restraint
and check the various adjustments to be
sure the child restraint is compatible with
your child. Choose a child restraint that is
designed for your child’s height and weight.
Always follow all recommended procedures.
All U.S. states and Canadian provinces or
territories require that infants and small
children be restrained in an approved child
restraint at all times while the vehicle is
being operated. Canadian law requires the
top tether strap on forward-facing child
restraints be secured to the designated
anchor point on the vehicle.LATCH label location
Lower Anchors and Tethers for
CHildren System (LATCH) (models
with rear seat)
Your vehicle is equipped with special anchor
points that are used with the LATCH (Lower
Anchors and Tethers for CHildren) system
compatible child restraints. This system may
also be referred to as the ISOFIX or ISOFIX
compatible system. With this system, you do not
have to use a vehicle seat belt to secure the
child restraint.
