2019 NISSAN FRONTIER PRO-4X Owners Manual

The front air bags operate only when the
ignition switch is in the ON or START po-
sition.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.Front passenger air bag and status light

seat, contrary to the instructions in this
manual. Always be sure that you and all
vehicle occupants are seated and re-
strained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger 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 illu-
minated (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 or not
using the seat belt properly.
If a child restraint must be used in the front
seat, the front passenger air bag status
light may or may not be illuminated, de-
pending on the size of the child and the
type of child restraint being used. If the air
bag status light is not illuminated (indicat-
ing 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 air bagstatus light is not illuminated, reposition
the occupant or child restraint in a rear
seat.
If the front passenger air bag status light
will not illuminate even though you believe
that the child restraint, the seat belts and
the occupant are properly positioned, the
system may be sensing an unoccupied
seat (in which case the air bag is OFF). A
NISSAN dealer can check that the system is
OFF by using a special tool. However, until
you have confirmed with a dealer that your
air bag is working properly, reposition the
occupant or child restraint in a rear seat.
The NISSAN Advanced Air Bag System and
front passenger air bag status light will
take a few seconds to register a change in
the passenger seat status. For example, if a
large adult who is sitting in the front pas-
senger seat exits the vehicle, the front pas-
senger air bag status light will go from OFF
to ON for a few seconds and then to OFF.
This is normal system operation and does
not indicate a malfunction.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air

∙ Do not make unauthorized changesto your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
∙ Tampering with the front air bag sys- tem may result in serious personal in-
jury. Tampering includes changes to
the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad and
above the instrument panel or by in-
stalling additional trim material
around the air bag system.
∙ Modif ying or tampering with the front passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing ma-
terial on the seat cushion or by install-
ing additional trim material, such as
seat covers, on the seat that are not
specifically designed to assure proper
air bag operation. Additionally, do not
stow any objects under the front pas-
senger seat or the seat cushion and
seatback. Such objects may interfere
with the proper operation of the occu-
pant classification sensor (pressure
sensor). ∙ 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 that you visit a NISSAN dealer for work on and around
the front air bag. It is also recom-
mended that you visit a NISSAN dealer
for installation of electrical equip-
ment. The Supplemental Restraint
System (SRS) wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the air bag
system.
∙ A cracked windshield should be re- placed immediately by a qualified re-
pair facility. A cracked windshield
could affect the function of the
supplemental 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 front air
bag system and guide the buyer to the
appropriate sections in this Owner’s
Manual.
1-86Safety—Seats, seat belts and supplemental restraint system

WARNING
∙ Do not place any objects near theseatback of the front seats. Also, do
not place any objects (an umbrella,
bag, etc.) between the front door fin-
isher and the front seat. Such objects
may become dangerous projectiles
and cause injury if a side air bag
inflates.
∙ Right af ter inflation, several side air bag and curtain air bag system com-
ponents 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 side air bag and curtain air bag
systems. This is to prevent damage to
or accidental inflation of the side air
bag and curtain air bag systems.
∙ Do not make unauthorized changes to your vehicle’s electrical system,
suspension system or side panel. This
could affect proper operation of the
curtain air bag systems. ∙ Tampering with the side air bag sys-
tem may result in serious personal in-
jury. For example, do not change the
front seats by placing material near
the seatbacks or by installing addi-
tional trim material, such as seat cov-
ers, around the side air bag.
∙ It is recommended that you visit a NISSAN dealer for work on and around
the side air bag and curtain air bag. It
is also recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical
test equipment and probing devices
should not be used on the side air bag
or curtain air bag systems.
* The SRS wiring harness or connectors
are yellow or 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 sections in this
Owner’s Manual.
Seat belt with pretensioner(s)
(front seats)

∙ It is recommended that you visit aNISSAN dealer for work on and around
the pretensioner system. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. Unauthorized electrical
test equipment and probing devices
should not be used on the preten-
sioner system.
∙ If you need to dispose of the preten- sioner(s) or scrap the vehicle, it is rec-
ommended that you visit a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause per-
sonal injury.
The pretensioner system may activate
with the supplemental air bag system in
certain types of collisions. Working with the
seat belt retractor, the pretensioner(s) help
tighten the seat belt when the vehicle be-
comes involved in certain types of colli-
sions, helping to restrain front seat occu-
pants.
The pretensioner(s) are encased within the
seat belt retractor and to the seat belt an-
chor affixed to the floor of the vehicle.
These seat belts are used the same way as
conventional seat belts. When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Af ter the pretensioner(s’) activation, load
limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against
the chest.
