2019 NISSAN FRONTIER PRO-4X engine

WARNING
∙ Operating the engine with the aircleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it isn’t
there, and the engine backfires, you
could be burned. Do not drive with the
air cleaner removed, and be careful
when working on the engine with the
air cleaner removed.
∙ Never pour fuel into the throttle body or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry
of airborne dust and pollen particles and
reduces some objectionable outside
odors. The filter is located behind the glove
box. For additional information on change
intervals, refer to the "Maintenance and
schedules" section of this manual.
To replace the filter, perform the following
procedure:
1. Open the glove box and press in on the sides so that it will open completely al-
lowing it to hang by the cord. 2. Gently lif t up on the tab
1.
3. Pull the filter cover toward you and then down
2.
4. Remove the old filter
3.
NOTE:
The filter is marked with air flow arrows.
The end of the filter with the arrow
should face the rear of the vehicle. The
arrows should face downward. 5. Insert the new filter into the housing and slide it over to the right.

ENGINE COMPARTMENT

FCC Notice:
For USA:
This device complies with Part 15 of the
FCC Rules. Operation is subject to the fol-
lowing two conditions: (1) This device
may not cause harmful interference, and
(2) this device must accept any interfer-
ence received, including interference
that may cause undesired operation.
Note:
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user’s author-
ity to operate the equipment.
For Canada:
This devise complies with Industry
Canada licence-exempt RSS standard(s).
Operation is subject to the following two
conditions: (1) this device may not cause
interference, and (2) this device must ac-
cept any interference, including interfer-
ence that may cause undesired opera-
tion of the device.HEADLIGHTS
The headlight is a semi-sealed beam type
which uses a replaceable headlight (halo-
gen) bulb. A bulb can be replaced from in-
side the engine compartment without re-
moving the headlight assembly.

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).

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.

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.

Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter
change intervals depend upon how you
use your vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:∙ repeated short distance driving at cold outside temperatures
∙ driving in dusty conditions
∙ extensive idling
∙ towing a trailer
∙ stop and go commuting
For additional information, refer to the
“Maintenance and schedules” section of
this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFC-134a (R-134a) and
NISSAN A/C system oil Type R (KLH00-
PAGRO) or the exact equivalents.

A NISSAN Towing Guide (U.S. only) is avail-
able on the website at
www.nissanusa.com. This guide includes
information on trailer towing capability and
the special equipment required for proper
towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed
the value specified in the “Towing
Load/Specification” chart found in this sec-
tion. The total trailer load equals trailer
weight plus its cargo weight.∙ When towing a trailer load of
3,500 lbs. (1,587 kg) or more, trailers
with a brake system MUST be used.
The maximum Gross Combined Weight
Rating (GCWR) should not exceed the value
specified in the following “Towing
Load/Specification” chart. The GCWR equals the combined weight of
the towing vehicle (including passengers
and cargo) plus the total trailer load. Tow-
ing loads greater than these or using im-
proper towing equipment could adversely
affect vehicle handling, braking and perfor-
mance.
The ability of your vehicle to tow a trailer is
not only related to the maximum trailer
loads, but also the places you plan to tow.
Tow weights appropriate for level highway
driving may have to be reduced for low
traction situations (for example, on slippery
boat ramps).Temperature conditions can also affect
towing. For example, towing a heavy trailer
in high outside temperatures on graded
roads can affect engine performance and
cause overheating. The engine protection
mode, which helps reduce the chance of
engine damage, could activate and auto-
matically decrease engine power. Vehicle
speed may decrease under high load. Plan
your trip carefully to account for trailer and
vehicle load, weather and road conditions.
