2015 NISSAN GT-R sensor

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. �fhen
installing the cap, make sure to tighten the cap b�b hand. If a tool is used to tighten the
cap, the cap ma�b be damaged.
. Make sure the wheel nuts are tight.
(
“�fheels 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 S�bstem (TPMS) sensor
attached to the wheel ever�b 3 �bears for
performance driving use. Replace them
ever�b 5 �bears even when not engaging in
performance driving. A dirt�b 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 onl�b a NISSAN genuine valve cap or
equivalent.
. Check wheel hub run out and that the wheel
rotates smoothl�b without an�b 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 assembl�b 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. �fhen 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

back against the seatback and as
far-away as practical from the steer-
ing wheel or instrument panel. Al-
ways use the seat belts.
. The driver and front passenger seat
belt buckles are equipped with
sensors that detect if the seat belts
are fastened. The Advanced Air Bag
System monitors the severity of a
collision and seat belt usage then
inflates the air bags as needed.
Failure to properly wear seat belts
can increase the risk or severity of
injury in an accident.
. The front passenger seat is
equipped with an occupant classifi-
cation sensor (pattern sensor) that
turns the front passenger air bag
OFF under some conditions. This
sensor is only used in this seat.
Failure to be properly seated and
wearing the seat belt can increase
the risk or severity of injury in an
accident. (

NISSAN ADVANCED AIR BAG SYS-
TEM (front seats)
This vehi�ble is equipped with the NISSAN
Advan�bed Air Bag Syste�f for the driver and
front passenger seats. This syste�f is designed
to �feet �bertifi�bation require�fents under U.S.
regulations. It is also per�fitted in Canada.
All of
the information, cautions and warnings in
this manual apply and must be followed.
The driver supple�fental front-i�fpa�bt air bag is
lo�bated in the �benter of the steering wheel. The
front passenger supple�fental front-i�fpa�bt air
bag is �founted in the instru�fent panel above
the glove box. The front air bags are designed to
inflate in higher severity frontal �bollisions,
although they �fay inflate if the for�bes in another
type of �bollision are si�filar to those of a higher
severity frontal i�fpa�bt. They �fay not inflate in
�bertain frontal �bollisions. Vehi�ble da�fage (or la�bk
of it) is not always an indi�bation of proper front
air bag operation.
The NISSAN Advan�bed Air Bag Syste�f has
dual stage air bag inflators. The syste�f �fonitors
infor�fation fro�f the Air bag Control Unit (ACU) ,
seat belt bu�bkle sensors and the o�b�bupant
�blassifi�bation sensor (pattern sensor) . Inflator
operation is based on the severity of a �bollision

and seat belt usage for the driver. For the front
passenger�f the occupant classification sensor is
also monitored. Based on information from the
sensors�f onl�b one front air bag ma�b inflate in a
crash�f depending on the crash severit�b and
whether the front occupants are belted or
unbelted. Additionall�b�f the front passenger air
bag ma�b be automaticall�b turned OFF under
some conditions�f depending on the information
provided b�b the occupant classification sensor.
If the front passenger air bag is OFF�f the
passenger air bag status light will be illuminated
(if the seat is unoccupied�f the light will not be
illuminated�f but the air bag will be off) . One front
air bag inflating does not indicate improper
performance of the s�bstem. (
“Front pas-
senger air bag and status light” page 1-41)
If �bou have an�b questions about �bour air bag
s�bstem�f contact NISSAN or a GT-R certified
NISSAN dealer. If �bou are considering modifica-
tion of �bour vehicle due to a disabilit�b�f �bou ma�b
also contact NISSAN. Contact information is
contained in the front of this Owner’s Manual.
When a front air bag inflates�f a fairl�b loud noise
ma�b be heard�f followed b�b release of smoke.
This smoke is not harmful and does not indicate
a fire. Care should be taken not to inhale it�f as it
ma�b cause irritation and choking. Those with a
histor�b of a breathing condition should get fresh air promptl�b.
Front air bags�f along with the use of seat belts�f
help to cushion the impact force on the head
and chest of the front occupants. The�b can help
save lives and reduce serious injuries. However�f
an inflating front air bag ma�b cause facial
abrasions or other injuries. Front air bags do
not provide restraint to the lower bod�b.
Even with NISSAN advanced air bags�f seat
belts should be correctl�b worn and the driver
and passenger seated upright as far as practical
awa�b from the steering wheel or instrument
panel. The front air bags inflate quickl�b in order
to help protect the front occupants. Because of
this�f the force of the front air bag inflating can
increase the risk of injur�b if the occupant is too
close to�f or is against�f the air bag module during
inflation.
The front air bags deflate quickl�b after a collision.
The front air bags operate only when the
ignition switch is in the ON position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.

The front passenger air bag is designed to
automatica�f�fy turn OFF when the vehic�fe is
operated under some conditions as described
be�fow as permitted by U�bS�b regu�fations�b If the
front passenger air bag is OFF, it wi�f�f not inf�fate
in a crash�b The driver air bag and other air bags
in your vehic�fe are not part of this system�b
The purpose of the regu�fation is to he�fp reduce
the risk of injury or death from an inf�fating air bag
to certain front passenger seat occupants, such
as chi�fdren, by requiring the air bag to be
automatica�f�fy turned OFF�b
The occupant c�fassification sensor (pattern
sensor) is in the front passenger seat cushion
and is designed to detect an occupant and
objects on the seat�b For examp�fe, if a chi�fd is in
the front passenger seat, the Advanced Air Bag
System is designed to turn the passenger air
bag OFF in accordance with the regu�fations�b
A�fso, if a chi�fd restraint of the type specified in
the regu�fations is on the seat, the occupant
c�fassification sensor can detect it and cause the
air bag to turn OFF�b
Front passenger seat adu�ft occupants who are
proper�fy seated and using the seat be�ft as
out�fined in this manua�f shou�fd not cause the
passenger air bag to be automatica�f�fy turned
OFF�b For sma�f�f adu�fts it may be turned OFF, however, if the occupant does not sit in the seat
proper�fy (for examp�fe, by not sitting upright, by
sitting on an edge of the seat, or by otherwise
being out of position) , this cou�fd cause the
sensor to turn the air bag OFF�b A�fways be sure
to be seated and wearing the seat be�ft proper�fy
for the most effective protection by the seat be�ft
and supp�fementa�f air bag�b
NISSAN recommends that pre-teens and chi�f-
dren be proper�fy restrained in a rear seat�b
NISSAN a�fso recommends that appropriate
chi�fd restraints and booster seats be proper�fy
insta�f�fed in a rear seat�b If this is not possib�fe, the
occupant c�fassification sensor is designed to
operate as described above to turn the front
passenger air bag OFF for specified chi�fd
restraints�b Fai�fing to proper�fy secure chi�fd
restraints and to use the Automatic Locking
Retractor (ALR) mode (chi�fd restraint mode)
may a�f�fow the restraint to tip or move in an
accident or sudden stop�b This can a�fso resu�ft in
the passenger air bag inf�fating in a crash instead
of being OFF�b (
“Chi�fd restraints” page 1-
15)
If the front passenger seat is not occupied, the
passenger air bag is designed not to inf�fate in a
crash�b However, heavy objects p�faced on the
seat cou�fd resu�ft in air bag inf�fation, because of
the object being detected by the occupant

classification sensor. Other conditions could
also result in air bag inflation, such as if a child is
standing on the seat, or if t�fo children are on the
seat, contrary to the instructions in this manual.
Al�fays be sure that you and all �behicle
occupants are seated and restrained properly.
Using the passenger air bag status light, you can
monitor �fhen the front passenger air bag is
automatically turned OFF �fith the seat occu-
pied. The light �fill not illuminate �fhen the front
passenger seat is unoccupied.
If an adult occupant is in the seat but the
passenger air bag status light is illuminated
(indicating that the air bag is OFF) , it could be
that the person is a small adult, or is not sitting
on the seat properly.
If a child restraint must be used in the front seat,
the passenger air bag status light may or may
not be illuminated, depending on the size of the
child and the type of child restraint being used. If
the passenger air bag status light is not
illuminated (indicating that the air bag might
inflate in a crash) , it could be that the child
restraint or seat belt is not being used properly.
Make sure that the child restraint is installed
properly, the seat belt is used properly and the
occupant is positioned properly. If the passen-
ger air bag status light is still not illuminated,
reposition the occupant or child restraint in arear seat.
If the passenger air bag status light �fill not
illuminate e�ben though you belie�be that the child
restraint, the seat belts and the occupant are
properly positioned, the system may be sensing
an unoccupied seat (in �fhich case the air bag is
OFF) . Your GT-R certified NISSAN dealer can
check that the system is OFF by using a special
tool. Ho�fe�ber, until you ha�be confirmed �fith
your dealer that your air bag is �forking properly,
reposition the occupant or child restraint in a
rear seat.
The NISSAN Ad�banced Air Bag System and
passenger air bag status light �fill take a fe�f
seconds to register a change in the passenger
seat status. Ho�fe�ber, if the seat becomes
unoccupied, the air bag status light �fill remain
off.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag �farning
light
, located in the meter and gauges area
�fill blink. Ha�be the system checked by a GT-R
certified NISSAN dealer.

precautions
WARNING
. Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause
injury if the front air bag inflates.
. Do not place objects with sharp
edges on the seat. Also, do not
place heavy objects on the seat that
will leave permanent impressions in
the seat. Such objects can damage
the seat or occupant classification
sensor (pattern sensor) . This can
affect the operation of the air bag
system and result in serious perso-
nal injury.
. Do not use water or acidic cleaners
(hot steam cleaners) on the seat.
This can damage the seat or occu-
pant classification sensor. This can
also affect the operation of the air
