engine overheat NISSAN FRONTIER 2023 User Guide

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
details.
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, it is recom-
mended that you have a NISSAN dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.
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.
10-6Technical and consumer information

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.
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. The re-
duced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful
when driving. If the vehicle cannot
maintain a safe driving speed, pull to
the side of the road in a safe area. Allow
the engine to cool and return to normal
operation. For additional information,
see “If your vehicle overheats” (P. 6-13).
CAUTION
Vehicle damage resulting from im-
proper towing procedures is not cov-
ered by NISSAN warranties.
Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load be-
tween 10 - 15% of the total trailer load or use
the trailer tongue load specified by the
trailer manufacturer. The tongue load
must be within the maximum tongue load
limits shown in the following “Towing Load/
Specification” chart. If the tongue load be-
comes excessive, rearrange cargo to allow
for proper tongue load.

10-28Technical and consumer information

• Avoid abrupt starts, acceleration or stops.
• Avoid sharp turns or lane changes.
• Always drive your vehicle at a moderatespeed.
• When backing up, hold the bottom of the steering wheel with one hand. Move your
hand in the direction in which you want
the trailer to go. Make small corrections
and back up slowly. If possible, have
someone guide you when you are back-
ing up.
Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you
must do so:
CAUTION
If you move the shif t lever to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer
wheels.
3. Af ter the wheel blocks are in place, slowly release the brake pedal until the
blocks absorb the vehicle load. 4. Apply the parking brake.
5. Shif t the transmission into P (Park).
6. Make sure the 4WD shif t indicator light (if
so equipped) indicates the transfer case
is in 4H, 4LO, or 2WD and that the ATP
light is off. If the 4WD shif t indicator light
is flashing, or the ATP light is ON, make
sure the transmission is in P (Park) and
turn the 4WD switch to 2WD or 4H. For
additional information, see “Automatic
transmission park warning light” (P. 2-13)
and “Using 4-wheel drive (4WD)” (P. 5-109).
7. Turn off the engine.
To drive away:
1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shif t the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks. • While going downhill, the weight of the
trailer pushing on the tow vehicle may
decrease overall stability. Therefore, to
maintain adequate control, reduce your
speed and shif t to a lower gear. Avoid
long or repeated use of the brakes when
descending a hill, as this reduces their
effectiveness and could cause overheat-
ing. Shif ting to a lower gear instead pro-
vides “engine braking” and reduces the
need to brake as frequently.
• If the engine coolant temperature rises to a high temperature, see “If your vehicle
overheats” (P. 6-13).
• Trailer towing requires more fuel than normal circumstances.
• Avoid towing a trailer for your vehicle's first 500 miles (805 km).
• For the first 500 miles (805 km) that you do tow, do not drive over 50 mph (80
km/h).
• Have your vehicle serviced more of ten than at intervals specified. For additional
information, see the “Maintenance and
schedules” section of this manual.
• When making a turn, your trailer wheels will be closer to the inside of the turn than
your vehicle wheels. To compensate for
this, make a larger than normal turning
radius during the turn.
10-38Technical and consumer information

• Crosswinds and rough roads will ad-versely affect vehicle/trailer handling,
possibly causing vehicle sway. When be-
ing passed by larger vehicles, be pre-
pared for possible changes in crosswinds
that could affect vehicle handling.
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 conditions
allow. This combination will help stabilize
the vehicle
– Do not correct trailer sway by steering or applying the brakes.
2. When the trailer sway stops, gently apply 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 normal
passing. Remember, the length of the
trailer must also pass the other vehicle
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 allow for greater stopping distances while tow-
ing 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 vehicles
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.
Tow mode (if so equipped)
Using tow mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Press the TOW MODE switch to acti-
vate tow mode. The indicator light on the
TOW MODE switch illuminates when tow
mode is selected. Press the TOW MODE
switch again to turn tow mode off. Tow
mode is automatically canceled when the
ignition switch is turned off.
Tow mode includes the following features:
• Grade logic — Adjusts transmission shif ts
when pulling a trailer or hauling a load up
a grade.
• Downhill Speed Control (DSC) — auto- matically downshif ts when driving down
a grade with a trailer or heavy load to help
control vehicle speed.
