2018 NISSAN FRONTIER check engine light

E-15 can only be used in vehicles designed
to run on E-15 fuel. U.S. government regula-
tions require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percent-
age for that region.
E–85 fuel
E-85 fuel is a mixture of approximately 85%
fuel ethanol and 15% unleaded gasoline.
E-85 can only be used in a Flexible Fuel
Vehicle (FFV). Do not use E-85 in your ve-
hicle. U.S. government regulations require
fuel ethanol dispensing pumps to be iden-
tified by a small, square, orange and black
label with the common abbreviation or the
appropriate percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting ad-
ditive. NISSAN does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMT
content, not all do, so you may have to
consult your gasoline retailer for more de-
tails.
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 abovesymptoms 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.
FUEL RECOMMENDATION (for
VQ40DE models)
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
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.
∙ Using a fuel other than that specified could adversely affect the emission
control system, and may also affect
the warranty coverage.

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.
WARNING
∙ Ethanol vapors are extremely flam-mable and could cause serious per-
sonal injury.
∙ Never have any smoking materials lit in or near the vehicle when removing
the fuel filler cap or filling the tank.
∙ Do not use E-85 as a cleaning agent and never use it near an open flame.
Fuel requirements
Your vehicle will operate on both unleaded
regular gasoline with an octane rating of at
least 87 AKI (Anti-Knock Index) number (Re-
search octane number 91), or E-85 fuel, or
any mixture of these two.
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.
10-42Technical and consumer information

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.
