NISSAN 370Z COUPE 2018 Repair Manual

tion.
The NISSAN Advanced Air Bag System has
dual stage air bag inflators. The system
monitors information from the crash
zone sensor, the Air bag Control Unit
(ACU), seat belt buckle switches and the
occupant classification sensor (pattern
sensor). Inflator operation is based on
the severity of a collision and seat belt
usage for the driver. For the front pas-
senger, the occupant classification sensor
is also monitored. Based on information
from the sensors, only one front air bag
may inflate in a crash, depending on the
crash severity and whether the front
occupants are belted or unbelted. Addi-
tionally, the front passenger air bag may
be automatically turned OFF under some
conditions, depending on the information
provided by the occupant classification
sensor. If the front passenger air bag is
OFF, the front passenger air bag status
light will be illuminated (if the seat is
unoccupied, the light will not be illumi-
nated, but the air bag will be off). (See
“Front passenger air bag and status light”
(P.1-38) for further details.) One front air
bag inflating does not indicate improper
performance of the system.
If you have any questions about your air
bag system, it is recommended you visit a
NISSAN dealer to obtain informationabout the system. If you are considering
modification of your vehicle due to a
disability, you may also contact a NISSAN
dealer. Contact information is contained
in the front of this Owner’s Manual.
When a front air bag inflates, a fairly loud
noise may be heard, followed by release
of smoke. This smoke is not harmful and
does not indicate a fire. Care should be
taken not to inhale it, as it may cause
irritation and choking. Those with a
history of a breathing condition should
get fresh air promptly.
Front air bags, along with the use of seat
belts, help to cushion the impact force on
the head and chest of the front occu-
pants. They can help save lives and
reduce serious injuries. However, an in-
flating front air bag may cause facial
abrasions or other injuries. Front air bags
do not provide restraint to the lower
body.
Even with NISSAN advanced air bags, seat
belts should be correctly worn and the
driver and passenger seated upright as
far as practical away from the steering
wheel or instrument panel. The front air
bags inflate quickly in order to help
protect the front occupants. Because of
this, the force of the front air bag inflating
can increase the risk of injury if the
occupant is too close to, or is against,the air bag module during inflation.
The front air bags deflate quickly after a
collision.
The supplemental front air bags oper-
ate 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 supple-
mental air bag warning light will turn
off after about 7 seconds if the system
is operational.

light
WARNING
The front passenger air bag is de-
signed to automatically turn OFF
under some conditions. Read this
section carefully to learn how it
operates. Proper use of the seat,
seat belt and child restraints is ne-
cessary for most effective protec-
tion. Failure to follow all
instructions in this manual concern-
ing the use of seats, seat belts andchild restraints can increase the risk
or severity of injury in an accident.
Status light:
The front passenger air bag status light
is located on the instrument panel.
After the ignition switch is placed in the
ON position, the front passenger air bag
status light illuminates for about 7 sec-
onds and then turns off or illuminates
depending on the front passenger seat
occupied status. The light operates as
follows:
. Unoccupied front passenger seat: The
is OFF and the front passenger air
bag is OFF and will not inflate in a
crash.
. Front passenger seat occupied by a
small adult, child or child restraint as
outlined in this section: The
illu-
minates to indicate that the front
passenger air bag is OFF and will not
inflate in a crash.
. Occupied front passenger seat and
the front passenger meets the condi-
tions outlined in this section: The light
is OFF to indicate that the front
passenger air bag is operational. Front passenger air bag:
The front passenger air bag is designed
to automatically turn OFF when the
vehicle is operated under some condi-
tions as described below as permitted by
U.S. regulations. If the front passenger air
bag is OFF, it will not inflate in a crash. The
driver air bag and other air bags in your
vehicle are not part of this system.
The purpose of the regulation is to help
reduce the risk of injury or death from an
inflating air bag to certain front passen-
ger seat occupants, such as children, by
requiring the air bag to be automatically
turned OFF.
The occupant classification sensor (pat-
tern sensor) is in the front passenger seat
cushion and is designed to detect an
occupant and objects on the seat. For
example, if a child is in the front passen-
ger seat, the Advanced Air Bag System is
designed to turn the front passenger air
bag OFF in accordance with the regula-
tions. Also, if a child restraint of the type
specified in the regulations is on the seat,
the occupant classification sensor can
detect it and cause the air bag to turn
OFF.
Front passenger seat adult occupants
who are properly seated and using the
seat belt as outlined in this manual
should not cause the front passenger air

bag to be automatically turned OFF. For
small adults it may be turned OFF, how-
ever, if the occupant does not sit in the
seat properly (for example, by not sitting
upright, by sitting on an edge of the seat,
or by otherwise being out of position), this
could cause the sensor to turn the air bag
OFF. Always be sure to be seated and
wearing the seat belt properly for the
most effective protection by the seat belt
and supplemental air bag.
The occupant classification sensor is
designed to operate as described above
to turn the front passenger air bag OFF
for specified child restraints. Failing to
properly secure child restrains and to use
the ALR mode (child restraint mode) may
allow the restraint to tip or move in an
accident or sudden stop. This can also
result in the front passenger air bag
inflating in a crash instead of being OFF.
(See “Child restraints” (P.1-19) for proper
use and installation.)
If the front passenger seat is not occu-
pied, the front passenger air bag is
designed not to inflate in a crash. How-
ever, heavy objects placed on the seat
could result in air bag inflation, because of
the object being detected by the occu-
pant classification sensor. Other condi-
tions could also result in air bag inflation,
such as if a child is standing on the seat,or if two children are on the seat, contrary
to the instructions in this manual. Always
be sure that you and all vehicle occupants
are seated and restrained properly.
Using the front passenger air bag status
light, you can monitor when the front
passenger air bag is automatically turned
OFF with the seat occupied. The light will
not illuminate when the front passenger
seat is unoccupied.
If an adult occupant is in the seat but the
front 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 front passenger air bag
status light may or may not be illumi-
nated, depending on the size of the child
and the type of child restraint being used.
If the front 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 occu-
pant is positioned properly. If the front
passenger air bag status light is still not
illuminated, try a different child restraint.
If the front passenger air bag status light
will not illuminate even though you be-
lieve that the child restraint, the seat belts
and the occupant are properly positioned,
the system may be sensing an unoccu-
pied seat (in which case the air bag is
OFF). Your NISSAN dealer can check that
the system is OFF by using a special tool.
However, until you have confirmed with
your dealer that your air bag is working
properly, do not transport a child in this
vehicle.
The NISSAN Advanced Air Bag System
and front passenger air bag status light
will take a few seconds to register a
change in the front passenger seat sta-
tus. However, if the seat becomes unoc-
cupied, the front passenger air bag status
light will remain off.
If a malfunction occurs in the front
passenger air bag system, the supple-
mental air bag warning light
, located
in the meter and gauges area will blink.
Have the system checked. It is recom-
mended you visit a NISSAN dealer for this
service.

WARNING
.Do not place any objects on the
steering wheel pad or on the
instrument panel. Also, do not
place any objects between any
occupant and the steering wheel
or instrument panel. Such objects
may become dangerous projec-
tiles 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 impres-
sions in the seat. Such objects
can damage the seat or occupant
classification sensor (pattern
sensor). This can affect the op-
eration of the air bag system and
result in serious personal injury.
. Do not use water or acidic clea-
ners (hot steam cleaners) on the
seat. This can damage the seat or
occupant classification sensor.
This can also affect the operation
of the air bag system and result in
serious personal injury. .
Immediately after inflation, sev-
eral front air bag system compo-
nents will be hot. Do not touch
them; you may severely burn
yourself.
. No unauthorized changes should
be made to any components or
wiring of the air bag system. This
is to prevent accidental inflation
of the supplemental air bag or
damage to the supplemental air
bag system.
. Do not make unauthorized
changes to your vehicle’s electri-
cal system, suspension system or
front end structure. This could
affect proper operation of the
front air bag system.
. Tampering with the front air bag
system may result in serious per-
sonal injury. Tampering includes
changes to the steering wheel
and the instrument panel assem-
bly by placing material over the
steering wheel pad and above the
instrument panel or by installing
additional trim material around
the air bag system.
. Modifying or tampering with the
front passenger seat may result
in serious personal injury. For example, do not change the front
seats by placing material on the
seat cushion or by installing ad-
ditional trim material, such as
seat covers, on the seat that is
not specifically designed to as-
sure proper air bag operation.
Additionally, do not stow any
objects under the front passen-
ger seat or the seat cushion and
seatback. Such objects may inter-
fere with the proper operation of
the occupant classification sen-
sor.
. No unauthorized changes should
be made to any components or
wiring of the seat belt system.
This may affect the front air bag
system. Tampering with the seat
belt system may result in serious
personal injury.
. It is recommended you visit a
NISSAN dealer for work on and
around the front air bag. It is also
recommended you visit a NISSAN
dealer for installation of electrical
equipment. The Supplemental
Restraint System (SRS) wiring
harnesses* should not be modi-
fied or disconnected. Unauthor-
ized electrical test equipment
and probing devices should not

be used on the air bag system.
. A cracked windshield should be
replaced immediately by a quali-
fied repair facility. A cracked
windshield could affect the func-
tion of the supplemental air bag
system.

FRONT SEAT-MOUNTED SIDE-IM-
PACT AND ROOF/DOOR-MOUNTED
CURTAIN SIDE-IMPACT AND ROLL-
OVER (if so equipped) SUPPLEMEN-
TAL AIR BAG SYSTEMS
The side air bags are located in the
outside of the seatback of the front seats.
The curtain air bags are located in the
side roof rails (Coupe) or upper side of the
door trim (Roadster). All of the informa-
tion, cautions and warnings in this
manual apply and must be followed.
The side air bags and curtain air bags are
designed to inflate in higher severity side
collisions, although they may inflate if the
forces in another type of collision are similar to those of a higher severity side
impact. They are designed to inflate on
the side where the vehicle is impacted.
They may not inflate in certain side
collisions.
Roof-mounted curtain air bags are also
designed to inflate in certain types of
rollover collisions or near rollovers (Coupe
models). As a result, certain vehicle move-
ments may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not
always an indication of proper supple-
mental side air bag and curtain air bag
operation.
When side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by release of smoke. This smoke
is not harmful and does not indicate a fire.
Care should be taken not to inhale it, as it
may cause irritation and choking. Those
with a history of a breathing condition
should get fresh air promptly.
Side air bags, along with the use of seat
belts, help to cushion the impact force on
the chest and pelvis of the front occu-
pants. Curtain air bags help to cushion
the impact force to the head of occu-
pants. They can help save lives and
reduce serious injuries. However, inflating
side air bags and curtain air bags may
cause abrasions or other injuries. Side air
Safety — Seats, seat belts and supplemental restraint system1-41

1-42Safety — Seats, seat belts and supplemental restraint system
bags and curtain air bags do not provide
restraint to the lower body.
The seat belts should be correctly worn
and the driver and passenger seated
upright as far as practical away from the
side air bag, and seated as far away as
practical from the door finishers and side
roof rails. The side air bags and curtain air
bags inflate quickly in order to help
protect the occupants. Because of this,
the force of the side air bags and curtain
air bags inflating can increase the risk of
injury if the occupant is too close to, or is
against, these air bag modules during
inflation. The side air bags and curtain air
bags will remain inflated for a short
period of time. For Coupe models, in a
rollover, the curtain air bags on both side-
impact situations, the curtain air bags will
remain inflated for a short period of time.
The side air bags and curtain air bags
operate only when the ignition switch is
in the ON position.
After placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The air bag
warning light will turn off after about 7
seconds if the systems are operational.
WARNING
.Do not place any objects near the
seatback of the front seats. Also,
do not place any objects (an
umbrella, bag, etc.) between the
front door finisher and the front
seat. Such objects may become
dangerous projectiles and cause
injury if a side air bag inflates.
. Right after inflation, several side
air bags and curtain air bag sys-
tem components will be hot. Do
not touch them; you may severely
burn yourself.
. No unauthorized changes should
be made to any components or
wiring of side air bag and curtain
air bag systems. This is to prevent
accidental inflation of the side air
bag and curtain air bag or da-
mage to side air bag and curtain
air bag systems.
. Do not make unauthorized
changes to your vehicle’s electri-
cal system, suspension system or
side panel. This could affect prop-
er operation of the side air bag
and curtain air bag systems. .
Tampering with the air bag sys-
tem may result in serious perso-
nal injury. For example, do not
change the front seats by placing
material near the seatback or by
installing additional trim materi-
al, such as seat covers, around
the side air bags.
. It is recommended you visit a
NISSAN dealer for work on and
around the pretensioner system.
It is also recommended you visit a
NISSAN dealer for installation of
electrical equipment. The SRS
wiring harnesses* should not be
modified or disconnected. Un-
authorized electrical test equip-
ment and probing devices should
not be used on the side-impact
air bag system.
* The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion.
When selling your vehicle, we request that
you inform the buyer about the side air
bag and curtain air bag systems and
guide the buyer to the appropriate sec-
tions in this Owner’s Manual.

SEAT BELTS WITH PRETENSIONERS
(front seats)
WARNING
.The pretensioners cannot be re-
used after activation. They must
be replaced together with the
retractor and buckle as a unit.
. If the vehicle becomes involved in
a collision but a pretensioner is
not activated, be sure to have the
pretensioner system checked
and, if necessary, replaced. It is
recommended you visit a NISSAN
dealer for this service.
. No unauthorized changes should
be made to any components or
wiring of the pretensioner sys-
tem. This is to prevent damage to
or accidental activation of the
pretensioners. Tampering with
the pretensioner system may re-
sult in serious personal injury.
. It is recommended you visit a
NISSAN dealer for work on and
around the pretensioner system.
It is also recommended you visit a
NISSAN dealer for installation of
electrical equipment. Unauthor-
ized electrical test equipment and probing devices should not
be used on the pretensioner sys-
tem.
. If you need to dispose of the
pretensioner or scrap the vehicle,
it is recommended you visit a
NISSAN dealer for this service.
Correct pretensioner disposal
procedures are set forth in the
appropriate NISSAN Service Man-
ual. Incorrect disposal procedures
could cause personal injury.
The pretensioner system may activate
with the supplemental air bag system in
certain types of collisions. Working with
the seat belt retractor, it helps tighten the
seat belt when the vehicle becomes
involved in certain types of collisions,
helping to restrain front seat occupants.
The pretensioner is encased with the seat
belt retractor. These seat belts are used
the same way as conventional seat belts.
When a pretensioner seat belt activates,
smoke is released and a loud noise may
be heard. The smoke is not harmful, and it
does not indicate a fire. Care should be
taken not to inhale it as it may cause
irritation and choking. Those with a
history of a breathing condition should
get fresh air promptly. After pretensioner activation, load limiters
allow the seat belt to release webbing (if
necessary) to reduce forces against the
chest.
The supplemental air bag warning lightis used to indicate malfunctions in
the pretensioner system. (See “Supple-
mental air bag warning light” (P.1-44) for
more details.) If the operation of the
supplemental air bag warning light indi-
cates there is a malfunction, have the
system checked. It is recommended you
visit a NISSAN dealer for this service.
When selling your vehicle, we request that
you inform the buyer about the seat belt
pretensioners and guide the buyer to the
appropriate sections in this Owner’s Man-
ual.
