2019 NISSAN FRONTIER check engine light

Doors and engine hood:Check that the
doors and engine hood operate properly.
Also ensure that all latches lock securely.
Lubricate hinges, latches, latch pins, rollers
and links if necessary. Make sure that the
secondary latch keeps the hood from
opening when the primary latch is re-
leased.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Lights*: Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Tires should be rotated ev-
ery 5,000 miles (8,000 km).
Tires*: Check the pressure with a gauge
of ten and always prior to long distance
trips. If necessary, adjust the pressure in all
tires, including the spare, to the pressure
specified. Check carefully for damage, cuts
or excessive wear. Tire Pressure Monitoring System (TPMS)
transmitter components:
Replace the
TPMS transmitter grommet seal, valve core
and cap when the tires are replaced due to
wear or age.
Wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect un-
even or abnormal tire wear, there may be a
need for wheel alignment. If the steering
wheel or seat vibrates at normal highway
speeds, wheel balancing may be needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield: Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled maintenance,
cleaning the vehicle, etc. Accelerator pedal:
Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Automatic transmission P (Park) mecha-
nism: On a fairly steep hill check that the
vehicle is held securely with the shif t lever
in the P (Park) position without applying any
brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
Maintenance and schedules9-3

Seats:Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering system, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery (for maintenance free batter-
ies)*: This vehicle is equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health. Brake and clutch (if so equipped) fluid
level*:
Make sure that the fluid level is be-
tween the MAX and MIN lines on the reser-
voir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
parking the vehicle on a level spot and
turning off the engine. Wait more than
15 minutes for the oil to drain back into the
oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, refer to “Exhaust gas (carbon mon-
oxide)” in the “Starting and driving” section
of this manual.
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
9-4Maintenance and schedules

Af termarket fuel additives
NISSAN does not recommend the use of
any af termarket fuel additives (for ex-
ample, fuel injector cleaner, octane
booster, intake valve deposit removers,
etc.) which are sold commercially. Many of
these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can
cause persistent, heavy “spark knock.”
(“Spark knock” is a metallic rapping
noise.) If severe, this can lead to engine
damage. If you detect a persistent heavy
spark knock even when using gasoline
of the stated octane rating, or if you hear
steady spark knock while holding a
steady speed on level roads, have a
NISSAN dealer correct the condition. Fail-
ure to correct the condition is misuse of
the vehicle, for which NISSAN is not re-
sponsible.Incorrect ignition timing may result in
spark knock, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not
a cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
FLEXIBLE FUEL VEHICLE (FFV) FUEL
RECOMMENDATION (if so
equipped)
Your vehicle is designed to use (E-85) Fuel
Ethanol, “Regular” unleaded regular gaso-
line or any percentage of the two fuels
combined.
U.S. government regulations require Fuel
Ethanol dispensing pumps to have a
small, square, orange and black label
with the common abbreviation or the
appropriate percentage for that region.
CAUTION
Use of other fuels such as Fuel Metha-
nol may cause powertrain damage or a
loss of vehicle performance.
Under no circumstances should a
leaded gasoline be used, because this
will cause damage to the three-way
catalyst.
General information
This information is for Flexible Fuel Vehicles
(FFV) only. FFV vehicles can be identified by
the fuel filler door label that states Ethanol
(E-85) or Unleaded Gasoline Only. This sec-
tion only covers those subjects that are
unique to Flexible Fuel Vehicles.
CAUTION
Only vehicles with the E-85 filler door
label can operate on E-85. Fuel system
or other damage can occur if E-85 is
used in vehicles that are not designed
to run on E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
Technical and consumer information10-9

∙ When making a turn, your trailer wheelswill be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
∙ Crosswinds and rough roads will ad- versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be pre-
pared for possible changes in cross-
winds that could affect vehicle han-
dling.
Do the following if the trailer begins to
sway: 1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer
as straight ahead as the road condi-
tions allow. This combination will help
stabilize the vehicle
– Do not correct trailer sway by steer- ing or applying the brakes.
2. When the trailer sway stops, gently ap- ply the brakes and pull to the side of the
road in a safe area.
3. Try to rearrange the trailer load so it is balanced as described in this section. ∙ Be careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than nor-
mal passing. Remember, the length of
the trailer must also pass the other ve-
hicle before you can safely change
lanes.
∙ Downshif t the transmission to a lower gear for engine braking when driving
down steep or long hills. This will help
slow the vehicle without applying the
brakes.
∙ Avoid holding the brake pedal down too long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
∙ Increase your following distance to al- low for greater stopping distances
while towing a trailer. Anticipate stops
and brake gradually.
∙ NISSAN recommends that the cruise control not be used while towing a
trailer.
∙ Some states or provinces have specific regulations and speed limits for ve-
hicles that are towing trailers. Obey the
local speed limits. ∙ Check your hitch, trailer wiring harness
connections, and trailer wheel lug nuts
af ter 50 miles (80 km) of travel and at
every break.
∙ When launching a boat, don’t allow the water level to go over the exhaust tail
pipe or rear bumper.
∙ Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, refer
to the “Do-it-yourself ” section in this
manual.
FLAT TOWING – 4WD WITH
AUTOMATIC TRANSMISSION
Towing a vehicle behind a recreational ve-
hicle, such as a motor home, is sometimes
called flat towing.
Technical and consumer information10-41

If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready” condi-
tion. Before taking the I/M test, check the
vehicle’s inspection/maintenance test
readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds, the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a ve-
hicle’s systems performed. The EDR is de-
signed to record data related to vehicle dy-
namics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to re-
cord such data as:
∙ How various systems in your vehicle were operating;
∙ Whether or not the driver and passen- ger safety belts were buckled/fastened;
∙ How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
∙ How fast the vehicle was traveling.
∙ Sounds are not recorded. These data can help provide a better un-
derstanding of the circumstances in which
crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-
trivial crash situation occurs; no data are
recorded by the EDR under normal driving
conditions and no personal data (e.g.
name, gender, age and crash location) are
recorded. However, other parties, such as
law enforcement, could combine the EDR
data with the type of personally identif ying
data routinely acquired during a crash in-
vestigation.
To read data recorded by an EDR, special
equipment is required and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer and NISSAN
dealer, other parties, such as law enforce-
ment, that have the special equipment, can
read the information if they have access to
the vehicle or the EDR. EDR data will only be
accessed with the consent of the vehicle
owner or lessee or as otherwise required or
permitted by law.
