2019 NISSAN FRONTIER inflation pressure

This vehicle is equipped with the NISSAN
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements
under U.S. regulations. It is also permitted in
Canada.However, all of the information,
cautions and warnings in this manual
still apply and must be followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
dashboard above the glove box. The front
air bags are designed to inflate in higher
severity frontal collisions, although they
may inflate if the forces in another type of
collision are similar to those of a higher
severity frontal impact. They may not in-
flate in certain frontal collisions. Vehicle
damage (or lack of it) is not always an indi-
cation of proper front air bag system op-
eration.
The NISSAN Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle sensors, occupant classifica-
tion sensor (pressure sensor) and passen-
ger seat belt tension sensor. Inflator opera-
tion is based on the severity of a collision
and seat belt usage for the driver. For the front passenger, it additionally monitors
the weight of an occupant or object on the
seat and seat belt tension. Based on infor-
mation 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 con-
ditions, depending on the weight detected
on the front passenger seat and how the
seat belt is used. If the front passenger air
bag is OFF, the front passenger air bag sta-
tus light will be illuminated (if the seat is
unoccupied, the light will not be illumi-
nated, but the air bag will be off ). For addi-
tional information, refer to “Front passen-
ger air bag and status light” in this section.
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 that you
visit a NISSAN dealer to obtain information
about the system. If you are considering
modification of your vehicle due to a dis-
ability, you may also contact NISSAN. Con-
tact 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 the re-lease of smoke. This smoke is not harmful
and does not indicate a fire. Care should be
taken to not inhale it, as it may cause irrita-
tion 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 face and chest of the front occupants.
They can help save lives and reduce seri-
ous injuries. However, an inflating front air
bag may cause facial abrasions or other
injuries. Front air bags do not provide re-
straint to the lower body.
Even with NISSAN Advanced Air Bags, seat
belts should be correctly worn and the
driver and front 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 in-
crease the risk of injury if the occupant is
too close to, or is against, the front air bag
module during inflation.
The front air bags deflate quickly af ter a
collision.
1-82Safety—Seats, seat belts and supplemental restraint system

Front passenger air bag
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below in accordance with U.S. regu-
lations. 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 passenger
seat occupants, such as children, by requir-
ing the air bag to be automatically turned
OFF. Certain sensors are used to meet the
requirements.
One sensor used is the occupant classifi-
cation sensor (pressure sensor). It is in the
bottom of the front passenger seat cush-
ion and is designed to detect an occupant
and objects on the seat by weight. It works
together with seat belt sensors described
in this section. For example, if a child is in
the front passenger seat, the NISSAN Ad-
vanced Air Bag System is designed to turn
the front passenger air bag OFF in accor-
dance with the regulations. Also, if a child
restraint of the type specified in the regula-
tions is on the seat, its weight and the
child’s weight can be detected and causethe air bag to turn OFF. Occupant classifi-
cation sensor operation can vary depend-
ing on the front passenger seat belt sen-
sors.
The front passenger seat belt sensors are
designed to detect if the seat belt is buck-
led and the amount of tension on the seat
belt, such as when it is in the Automatic
Locking Retractor (ALR) mode (child re-
straint mode). Based on the weight on the
seat detected by the occupant classifica-
tion sensor and the belt tension detected
on the seat belt, the NISSAN Advanced Air
Bag System determines whether the front
passenger air bag should be automatically
turned OFF as required by the regulations.
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, however, if the occu-
pant 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. In addition, if the
occupant improperly uses the seat belt in
the ALR mode, this could cause the air bag
to be turned OFF. Always be sure to beseated and wearing the seat belt properly
for the most effective protection by the
seat belt and supplemental air bag.
NISSAN recommends that pre-teens and
children be properly restrained in a rear
seat. NISSAN also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat. If
this is not possible, the occupant classifica-
tion sensor and seat belt sensors are de-
signed to operate as described above to
turn the front passenger air bag OFF for
specified child restraints as required by the
regulations. Failing to properly secure child
restraints and to use the ALR mode may
allow the restraint to tip or move in a colli-
sion or sudden stop. This can also result in
the passenger air bag inflating in a crash
instead of being OFF. For additional infor-
mation, refer to “Child restraints” in this sec-
tion.
If the front passenger seat is not occupied,
the front passenger air bag is designed not
to inflate in a crash. However, heavy objects
placed on the seat could result in air bag
inflation, because of the object’s weight de-
tected by the occupant classification sen-
sor. Other conditions could also result in air
bag inflation, such as if a child is standing
on the seat, or if two children are on the

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
WARNING
∙ The exhaust gas and the exhaust sys-tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system
components.
∙ Do not stop or park the vehicle over flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously re-
duce the three-way catalyst’s ability
to help reduce exhaust pollutants. ∙ Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if no-
ticeable loss of performance or other
unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended that you
visit a NISSAN dealer for this service.
∙ Avoid driving with an extremely low fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
∙ Do not race the engine while warming it up.
∙ Do not push or tow your vehicle to start the engine.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
Starting and driving5-3

∙ Tire pressure rises and falls dependingon the heat caused by the vehicle’s op-
eration and the outside temperature.
Do not reduce the tire pressure af ter
driving because the tire pressure rises
af ter driving. Low outside temperature
can lower the temperature of the air
inside the tire which can cause a lower
tire inflation pressure. This may cause
the low tire pressure warning light to
illuminate. If the warning light illumi-
nates, check the tire pressure for all four
tires.
∙ The Tire and Loading Information label is located in the driver’s door opening.
For additional information, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section and “Tire Pressure
Monitoring System (TPMS)” in the “In case of
emergency” section of this manual.
WARNING
∙ Radio waves could adversely affect electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use. ∙ If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull off
the road to a safe location and stop
the vehicle as soon as possible. Driv-
ing with under-inflated tires may per-
manently damage the tires and in-
crease the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light off. If you have a flat
tire, replace it with a spare tire as soon
as possible. For additional informa-
tion, refer to “Flat tire” in the “In case of
emergency ” section of this manual
for changing a flat tire. ∙ When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, the TPMS will not function
and the low tire pressure warning
light will flash for approximately
1 minute. The light will remain on af ter
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit a NISSAN dealer for this service.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CAUTION
Do not place metalized film or any
metal parts (antenna, etc.) on the win-
dows. This may cause poor reception of
the signals from the tire pressure sen-
sors, and the TPMS will not function
properly.

If you have a flat tire, refer to “Flat tire” in
the “In case of emergency ” section of
this manual.
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with TPMS. It
monitors tire pressure of all tires ex-
cept the spare. When the low tire
pressure warning light is lit and the
CHECK TIRE PRES (pressure) warning
message is displayed in the odom-
eter, one or more of your tires is sig-
nificantly under-inflated.
TPMS will activate only when the ve-
hicle is driven at speeds above
16 mph (25 km/h). Also, this system
may not detect a sudden drop in tire
pressure (for example, a flat tire while
driving).
For additional information, refer to
“Low tire pressure warning light” in
the “Instruments and controls” sec-
tion, “Tire Pressure Monitoring Sys-
tem (TPMS)” in the “Starting and driv-ing” section, and “Flat tire” in the “In
case of emergency” section of this
manual.
Tire inflation pressure
Check the tire pressures (including
the spare) of ten and always prior to
long distance trips. The recom-
mended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S.
certification label or the Tire and
Loading Information label under the
“Cold Tire Pressure” heading. The Tire
and Loading Information label is af-
fixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
∙ Most tires naturally lose air over time.
∙ Tires can lose air suddenly when driven over potholes or other ob-
jects or if the vehicle strikes a
curb while parking. The tire pressures should be
checked when the tires are cold. The
tires are considered COLD af ter the
vehicle has been parked for 3 or
more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.
Incorrect tire pressure, including
under inflation, may adversely af-
fect tire life and vehicle handling.
WARNING
∙ Improperly inflated tires can fail suddenly and cause an
accident.

∙ The Gross Vehicle Weight Rating(GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight
capacity is indicated on the Tire
and Loading Information label.
Do not load your vehicle beyond
this capacity. Overloading your
vehicle may result in reduced
tire life, unsafe operating condi-
tions due to premature tire fail-
ure, or unfavorable handling
characteristics and could also
lead to a serious accident. Load-
ing beyond the specified capac-
ity may also result in failure of
other vehicle components.
∙
Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure gauge
to ensure that the tire pressures
are at the specified level.

Spare tire (FULL SIZE TEMPORARY
USE ONLY spare tire)
When replacing a wheel without the TPMS
such as the spare tire, the TPMS will not
function.
Your vehicle may be equipped with a full
size spare that is a different size or brand
than the tires originally installed on the ve-
hicle. This full size spare tire is intended for
temporary use only and should be re-
placed at the first opportunity.
Observe the following precautions if the
FULL SIZE TEMPORARY USE ONLY spare tire
must be used. Otherwise, your vehicle
could be damaged or involved in an acci-
dent:
WARNING
To help reduce the risk of a crash which
may result in personal injury or death:
∙ The TEMPORARY FULL SIZE spare tireshould be used for emergency use
only. It should be replaced with the
standard tire at the first opportunity
to avoid possible tire or differential
damage. ∙ Drive carefully while the TEMPORARY
FULL SIZE spare tire is installed. Avoid
sharp turns and abrupt braking while
driving. The vehicle driving perfor-
mance may be affected when driving
on wet or snow covered roads.
∙ When the TEMPORARY FULL SIZE spare tire is installed, the Vehicle Dy-
namic Control (VDC) will normally not
be affected.
∙ When the TEMPORARY FULL SIZE spare tire is installed, the following
systems may not work correctly:
– Tire Pressure Monitoring System (TPMS)
– Forward Emergency Braking (FEB) (if so equipped)
∙ Periodically check the TEMPORARY FULL SIZE spare tire inflation pressure.
Always keep the TEMPORARY FULL
SIZE spare tire inflated to the pressure
specification shown on the Tire and
Loading Information label.
∙ With the TEMPORARY FULL SIZE spare tire installed do not drive the vehicle
at speeds faster than 50 mph
(80 km/h). ∙ When driving on roads covered with
snow or ice, the TEMPORARY FULL SIZE
spare tire should be used on the front
wheels and the original tire used on
the rear wheels. Use tire chains only
on the drive wheels.
∙ Do not use the TEMPORARY FULL SIZE spare tire on other vehicles.
∙ Do not use more than one TEMPO- RARY FULL SIZE spare tire at the same
time.
∙ Do not tow a trailer when the TEMPO- RARY FULL SIZE spare tire is installed.
