2021 NISSAN TITAN ignition

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.

Bumper towing
The Genuine NISSAN step bumper has pro-
visions to install a trailer hitch ball and is
designed to tow trailers of a maximum
weight of 5,000 lbs. (2,268 kg).
NOTE:
The trailer hitch ball cannot be installed
on the step bumper if the receiver-type
frame mounted hitch is installed on the
vehicle.
To install a trailer hitch ball cut out the circle
in the center of the step bumper
OA, then
remove it to install the trailer hitch ball.
Weight carrying hitches
A weight carrying or “dead weight” ball
mount is one that is designed to carry the
whole amount of tongue weight and gross
weight directly on the ball mount and on
the receiver.
Weight distribution hitch
This type of hitch is also called a “load-
leveling” or “equalizing” hitch. A set of bars
attach to the ball mount and to the trailer
to distribute the tongue weight (hitch
weight) of your trailer. Many vehicles can't
carry the full tongue weight of a given
trailer, and need some of the tongue
weight transferred through the frame and
pushing down on the front wheels. This
gives stability to the tow vehicle.
A weight-distributing hitch system (Class
IV) is recommended if you plan to tow trail-
ers with a maximum weight over 5,000 lbs.
(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may
affect the operation of trailer surge
brakes. If you are considering use of a
weight-distributing hitch system with a
surge brake-equipped trailer, check with
the surge brake, hitch or trailer manufac-
turer to determine if and how this can be
done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface. With the ignition switch in the ON posi-
tion and the doors closed, allow the ve-
hicle to stand for several minutes so that
it can level.
2. Measure the height of a reference point on the front and rear bumpers at the
center of the vehicle.
3. Attach the trailer to the vehicle and ad- just the hitch equalizers so that the front
bumper height is within0-.5inches (0 –
13 mm) of the reference height mea-
sured in step 2. The rear bumper should
be no higher than the reference height
measured in step 2.

• Use the Tow Mode or downshif t thetransmission 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 (if so equipped) not be used while
towing a trailer.
• While towing a trailer, do not use the fol- lowing systems (if so equipped):–– the Lane Departure Warning (LDW) sys- tem
–– the Blind Spot Warning (BSW) system
– – the Intelligent Cruise Control (ICC) sys-
tem
– – the Automatic Emergency Braking
(AEB) system
– – the Intelligent Forward Collision Warn-
ing (I-FCW) system
– – the Rear Automatic Braking (RAB) sys-
tem –
– the Moving Object Detection (MOD)
system
– – the Cross Traffic Alert system
–– the Rear Sonar system
• 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, see
the “Do-it-yourself ” section of this
manual.Tow mode
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.
Driving the vehicle in the tow mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel
economy may be reduced and the
transmission/engine driving characteris-
tics may feel unusual.

cerns please contact our Consumer
Information Centre toll free at 1-800-
387-0122.WARNING
A vehicle equipped with 4-Wheel Drive
(4WD) should never be tested using a
two wheel dynamometer (such as the
dynamometers used by some states
for emissions testing), or similar equip-
ment. Make sure you inform the test
facility personnel that your vehicle is
equipped with 4WD before it is placed
on a dynamometer. Using the wrong
test equipment may result in transmis-
sion damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” for an Inspection/
Maintenance (I/M) test of the emission
control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the ready condition can
be obtained by ordinary usage of the ve-
hicle. 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.
