2019 NISSAN FRONTIER Recommended service

Operation
The MIL will come on in one of two ways:∙ MIL on steady — An emission control system malfunction has been de-
tected. Check the fuel-filler cap if the
LOOSE FUEL CAP warning appears in
the trip computer. If the fuel-filler cap is
loose or missing, tighten or install the
cap and continue to drive the vehicle.
The
light should turn off af ter a
few driving trips. If the
light does
not turn off af ter a few driving trips, have
the vehicle inspected. It is recom-
mended that you visit a NISSAN dealer
for this service. You do not need to have
your vehicle towed to the dealer.
∙
MIL blinking — An engine misfire has been
detected which may damage the emis-
sion control system. To reduce or avoid
emission control system damage:
– Do not drive at speeds above 45 mph (72 km/h).
– Avoid hard acceleration or decelera- tion.
– Avoid steep uphill grades.
– If possible, reduce the amount of cargo being hauled or towed. The MIL may stop blinking and come on
steady. Have the vehicle inspected. It is rec-
ommended that you visit a NISSAN dealer
for this service. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary
could lead to poor driveability, reduced
fuel economy, and possible damage to
the emission control system.
Overdrive OFF indicator
light (if so equipped)
This light comes on when the overdrive
function is off.
The automatic transmission overdrive
function is controlled by the overdrive OFF
switch.
When the ignition switch is placed in the ON
position, the light comes on for about
2 seconds. If the light comes on at any
other time, it may indicate the automatic
transmission system is not functioning
properly. Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service. For additional information, refer to “Driving
the vehicle” in the “Starting and driving” sec-
tion of this manual.
Security indicator light (if
so equipped)
This light blinks when the ignition switch is
in the OFF, LOCK or ACC position. This func-
tion indicates the security systems
equipped on the vehicle are operational.
For additional information, refer to “Security
systems” in this section.
SET indicator light
The light comes on while the vehicle speed
is controlled by the cruise control system. If
the light blinks while the engine is running,
it may indicate the cruise control system is
not functioning properly. Have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
Slip indicator light
This indicator light will blink when the Ve-
hicle Dynamic Control (VDC) system is op-
erating, thus alerting the driver to the fact
that the road surface is slippery and the
vehicle is nearing its traction limits.
2-22Instruments and controls

The VDC light also comes on when you turn
the ignition key to the ON position. The light
will turn off af ter about 2 seconds if the
system is operational. If the light stays on
or comes on along with the
indicator
light while you are driving, have the VDC
system checked. It is recommended that
you visit a NISSAN dealer for this service.
If the battery is removed or discharged, the
VDC system is disabled and the VDC indi-
cator light will not turn off af ter 2 seconds
when the ignition switch is placed in the ON
position. To reset the system, you must
perform the reset procedure. For addi-
tional information, refer to “Vehicle Dy-
namic Control (VDC) system” in the “Start-
ing and driving” section of this manual.
If the light does not go off af ter performing
the reset procedure, have the traction con-
trol system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
While the VDC system is operating, you
might feel slight vibration or hear the sys-
tem working when starting the vehicle or
accelerating, but this is normal.
The VDC system will be disabled and the
VDC light will illuminate when the elec-
tronic locking rear differential (E-lock) sys- tem switch (if so equipped) is turned on
and the E-lock system is engaged. If the
E-lock system disengages or the switch is
turned off, the VDC system will be enabled
and the VDC light will turn off.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear
warnings. When a disc brake pad requires
replacement, it makes a high pitched
scraping sound when the vehicle is in mo-
tion, whether or not the brake pedal is de-
pressed. Have the brakes checked as soon
as possible if the warning sound is heard.
Key reminder chime
A chime sounds if the driver’s door is
opened while the key is lef t in the ignition
switch. Remove the key and take it with you
when leaving the vehicle.
Light reminder chime
With the ignition switch placed in the OFF
position, a chime sounds when the driver’s
door is opened if the headlights or parking
lights are on.

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 PUSH
(power) or
ON•OFF button to turn the radio on. If you
listen to the radio with the engine not run-
ning, the ignition 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 qual-
ity.
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

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.
