2018 NISSAN FRONTIER engine

OPERATING TIPS
The sunload sensor1, located on the top
center of the instrument panel, helps the
system maintain a constant temperature.
Do not put anything on or around this sen-
sor.
∙ When the engine coolant temperature and outside air temperature are low, the
air flow from the foot outlets may not
operate for a maximum of 150 seconds.
However, this is not a malfunction. Af ter
the coolant temperature warms up, air
flow from the foot outlets will operate
normally. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth’s ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, refer to “Air conditioner sys-
tem refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioning system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper
equipment.
RADIO
With the ignition placed in the ACC or ON
position, press the
(power) or ON•OFF
button to turn the radio on. If you listen to the
radio with the engine not running, the igni-
tion should be placed in the ACC position.
Radio reception is affected by station sig-
nal strength, distance from radio transmit-
ter, buildings, bridges, mountains and other
external influences. Intermittent changes
in reception quality normally are caused by
these external influences.
Using a cellular phone in or near the ve-
hicle may influence radio reception quality.
Radio reception
Your NISSAN radio system is equipped with
state-of-the-art electronic circuits to en-
hance radio reception. These circuits are
designed to extend reception range, and to
enhance the quality of that reception.
However, there are some general charac-
teristics of both FM and AM radio signals
that can affect radio reception quality in a
moving vehicle, even when the finest
equipment is used. These characteristics
are completely normal in a given reception
area and do not indicate any malfunction
in your NISSAN radio system.

When installing a CB, ham radio or car
phone in your vehicle, be sure to observe
the following precautions; otherwise, the
new equipment may adversely affect the
engine control system and other electronic
parts.
WARNING
∙ A cellular phone should not be usedfor any purpose while driving so full
attention may be given to vehicle op-
eration. Some jurisdictions prohibit
the use of cellular phones while
driving.
∙ If you must make a call while your ve- hicle is in motion, the hands free cellu-
lar phone operational mode (if so
equipped) is highly recommended.
Exercise extreme caution at all times
so full attention may be given to ve-
hicle operation.
∙ If you are unable to devote full atten- tion to vehicle operation while talking
on the phone, pull off the road to a
safe location and stop your vehicle.
CAUTION
∙ Keep the antenna as far away as pos-sible from the electronic control
modules.
∙ Keep the antenna wire more than 8 in (20 cm) away from the electronic con-
trol system harnesses. Do not route
the antenna wire next to any harness.

WARNING
∙ Do not leave children or adults whowould normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding
or shif ting. Do not place cargo higher
than the seatbacks. In a sudden stop
or collision, unsecured cargo could
cause personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; theycontain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death. ∙ If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
∙ Do not run the engine in closed spaces such as a garage.
∙ Do not park the vehicle with the en- gine running for any extended length
of time.
∙ Keep the rear vent windows, lif tgates, doors and trunk lids (if so equipped)
closed while driving, otherwise ex-
haust gases could be drawn into the
passenger compartment. If you must
drive with one of these open, follow
these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
∙ If electrical wiring or other cable con- nections must pass to a trailer
through the seal on the lif tgate or the
body, follow the manufacturer’s rec-
ommendation to prevent carbon
monoxide entry into the vehicle. ∙ The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system,
underbody, or rear of the vehicle.
∙ If a special body, camper, or other equipment is added for recreational
or other usage, follow the manufac-
turer’s recommendation to prevent
carbon monoxide entry into the ve-
hicle. Do not occupy these areas while
the engine is running even if the ve-
hicle is parked. Some recreational ve-
hicle appliances such as stoves, re-
frigerators, heaters, etc. may also
generate carbon monoxide.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-2Starting and driving

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.
