service NISSAN TITAN 2018 Owner´s Manual

NOTE:
This vehicle’s occupant classification
sensor system locks the classification
during driving so it is important that you
confirm that the front passenger is prop-
erly classified prior to driving. Also, the
occupant classification sensor system
may recalculate the weight of the occu-
pant when the vehicle comes to a stop
(i.e. stop light, stop sign, etc.), so front
passenger seat occupants should con-
tinue to remain seated as outlined
above.
Troubleshooting
If you think the front passenger air bag
status light is incorrect:1. If the light is ON with no front passenger and no objects on the front passenger
seat:
This may be due to the following condi-
tions that may be interfering with the
weight sensors: ∙ An object weighing over 1 kg (2.2 lbs.) hanging on the seat or placed in the
seatback pocket.
∙ A child restraint or other object pressing against the rear of the seatback. ∙ A rear passenger pushing or pulling on
the back of the front passenger seat.
∙ Forcing the front seat or seatback against an object on the seat or floor
behind it.
∙ An object placed under the front pas- senger seat.
∙ An object placed between the seat cushion and center console or between
the seat cushion and the door.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Re-
start the vehicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still ON af ter this, the vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service. 2. If the light is ON with an adult occupy- ing the front passenger seat: ∙ Occupant is a small adult — the air bag
light is functioning as intended. The
front passenger air bag is suppressed.
However, if the occupant is not a small
adult, then this may be due to the following
conditions that may be interfering with the
weight sensors: ∙ Occupant is not sitting upright, leaning against the seatback, and centered on
the seat cushion with his/her feet com-
fortably extended to the floor.
∙ A child restraint or other object pressing against the rear of the seatback.
∙ A rear passenger pushing or pulling on the back of the front passenger seat.
∙ Forcing the front seat or seatback against an object on the seat or floor
behind it.
∙ An object placed under the front pas- senger seat.
∙ An object placed between the seat cushion and center console or between
the seat cushion and the door.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Re-
start the vehicle and wait 1 minute.

Other supplemental front-impact air
bag precautions
WARNING
∙ Do not place any objects on the steer-ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steer-
ing wheel or instrument panel. Such
objects may become dangerous pro-
jectiles and cause injury if the front air
bags inflate.
∙ Immediately af ter inflation, several front air bag system 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
the supplemental 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 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.
∙ Removing or modif ying the front pas- senger seat may affect the function of
the air bag system and result in seri-
ous personal injury. ∙ 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 (weight
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.
Safety—Seats, seat belts and supplemental restraint system1-67

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)
WARNING
∙ The pretensioner(s) cannot be reused af ter activation. They must be re-
placed together with the retractor
and buckle as a unit.
∙ If the vehicle becomes involved in a collision but pretensioner(s) are not
activated, be sure to have the preten-
sioner system checked and, if neces-
sary, replaced. It is recommended that
you visit a NISSAN dealer for this
service.
∙ No unauthorized changes should be made to any components or wiring of
the pretensioner system. This is to
prevent damage to or accidental acti-
vation of the pretensioner(s). Tamper-
ing with the pretensioner system may
result in serious personal injury.
Safety—Seats, seat belts and supplemental restraint system1-79

∙ 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.
The supplemental air bag warning
light
is used to indicate malfunctions
in the pretensioner system. For additional
information, refer to "Supplemental air bag
warning light" in this section. If the opera-
tion of the supplemental air bag warning
light indicates there is a malfunction, have
the system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner’s
Manual. 1. SRS Air bag warning labels

vehicle, the front air bags, side air bags,
curtain air bags, pretensioner(s) and re-
lated parts should be pointed out to the
person performing the maintenance. The
ignition switch should always be placed in
the LOCK position when working under the
hood or inside the vehicle.
WARNING
∙ Once a front air bag, side air bag, orcurtain air bag has inflated, the air
bag module will not function again
and must be replaced. Additionally,
the activated pretensioner(s) must
also be replaced. The air bag module
and pretensioner(s) should be re-
placed. It is recommended that you
visit a NISSAN dealer for this service.
However, the air bag module and pre-
tensioner(s) cannot be repaired.
∙ The front air bag, side air bag, curtain air bag systems and the pretensioner
system should be inspected if there is
any damage to the front end or side
portion of the vehicle. It is recom-
mended that you visit a NISSAN dealer

∙ If you need to dispose of the supple- mental air bag or pretensioner sys-
tems or scrap the vehicle, it is recom-
mended that you visit a NISSAN
dealer. Incorrect disposal procedures
could cause personal injury. ∙ If there is an impact to your vehicle
from any direction, your Occupant
Classification Sensor (OCS) (if so
equipped) should be checked to verif y
it is still functioning correctly. It is rec-
ommended that you visit a NISSAN
dealer for this service. The OCS
(weight sensor) (if so equipped)
should be checked even if no air bags
deploy as a result of the impact. Fail-
ure to verif y proper OCS (weight sen-
sor) (if so equipped) function may re-
sult in an improper air bag
deployment resulting in injury or
death.
