2019 NISSAN MURANO heating

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, refer to “If your
vehicle overheats” in the “In case of
emergency ” section of this manual.
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 becomes excessive, rearrange cargo
to allow for proper tongue load.

Technical and consumer information10-19

∙ Be certain your rearview mirrors con-form to all federal, state or local regula-
tions. If not, install any mirrors required
for towing before driving the vehicle.
∙ Determine the overall height of the ve- hicle and trailer so the required clear-
ance is known.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle’s behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering sta-
bility and braking performance will be
somewhat different than under normal
driving conditions.
∙ Always secure items in the trailer to pre- vent load shif t while driving.
∙ Lock the trailer hitch coupler with a pin or lock to prevent the coupler from in-
advertently becoming unlatched.
∙ Avoid abrupt starts, acceleration or stops.
∙ Avoid sharp turns or lane changes.
∙ Always drive your vehicle at a moderate speed. ∙ 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 cor-
rections and back up slowly. If possible,
have someone guide you when you are
backing 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, trans-
mission 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. 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
overheating. Shif ting to a lower gear in-
stead provides “engine braking” and re-
duces the need to brake as frequently.
∙ If the engine coolant temperature rises to a high temperature, refer to “If your
vehicle overheats” in the “In case of
emergency” section of this owner’s
manual.
