2021 NISSAN TITAN sensor

•The driver is always responsible for
safety during parking and other ma-
neuvers. Always look around and
check that it is safe to do so before
parking.
• Read and understand the limitations
of the front and rear sonar system as
contained in this section. The colors
of the corner sonar indicator and the
distance guide lines in the front/rear
view indicate different distances to
the object.
• Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck's compressed-air
brakes or a pneumatic drill may af-
fect the function of the system; this
may include reduced performance or
a false activation.
• This function is designed as an aid to
the driver in detecting large station-
ary objects to help avoid damaging
the vehicle.
• The system is not designed to pre-
vent contact with small or moving
objects. Always move slowly. The
system will not detect small objects
below the bumper, and may not de-
tect objects close to the bumper or
on the ground. •
The system may not detect the fol-
lowing objects: fluff y objects such as
snow, cloth, cotton, glass, wool, etc.;
thin objects such as rope, wire and
chain, etc.; or wedge-shaped objects.
If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
stacles or false alarms.
CAUTION
• Excessive noise (such as audio sys-
tem volume or an open vehicle win-
dow) will interfere with the tone and
it may not be heard.
• Keep the sonar sensors (located on
the bumper fascia) free from snow,
ice and large accumulations of dirt.
Do not clean the sensors with sharp
objects. If the sensors are covered,
the accuracy of the sonar function
will be diminished.
SYSTEM OPERATION
The system informs with a visual and au-
dible alert of front obstacles when the shif t
lever is in the D (Drive) position and both
front and rear obstacles when the shif t le-
ver is in the R (Reverse) position.

5-126Starting and driving

Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you consult a NISSAN dealer if the area
around the sonar sensors is damaged due
to a collision.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry key fob.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
see “Engine cooling system” (P. 8-6).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P. 8-16).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, see
“Changing engine coolant” (P. 8-6).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used. For additional information, see “Tire chains” (P. 8-35).

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit, and the Tire Pressure Low — Add
Air warning appears in the vehicle informa-
tion display, one or more of your tires is
significantly under-inflated. If equipped, the
system also displays pressure of all tires
(except the spare tire) on the display screen
by sending a signal from a sensor that is
installed in each wheel. If the vehicle is be-
ing driven with low tire pressure, the TPMS
will activate and warn you of it by the low
tire pressure warning light. This system will
activate only when the vehicle is driven at
speeds above 16 mph (25 km/h). For addi-
tional information, see “Warning lights, indi-
cator lights and audible reminders” (P. 2-12)
and “Tire Pressure Monitoring System
(TPMS)” (P. 5-5).
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use. •
If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving af-
ter adjusting the tire pressure, a tire
may be flat or the TPMS may be mal-
functioning. If you have a flat tire, re-
place it with a spare tire as soon as
possible, If no tire is flat and all tires
are properly inflated, have the ve-
hicle checked. It is recom-
mended that you visit a NISSAN
dealer for this service •
When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately one minute. The light
will remain on af ter one minute. Have
your tires replaced and/or TPMS sys-
tem reset as soon as possible. It is
recommended that you visit a
NISSAN dealer for these services.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road and away from traffic.
2. Turn on the hazard warning flashers.
FLAT TIRE
In case of emergency6-3

In order to maintain the appearance of
your vehicle, it is important to take proper
care of it.
To protect the paint surfaces, wash your
vehicle as soon as you can:
• Af ter a rainfall to prevent possible dam-age from acid rain.
• Af ter driving on coastal roads.
• When contaminants such as soot, bird droppings, tree sap, metal particles or
bugs get on the paint surface.
• When dust or mud builds up on the sur- face.
Whenever possible, store or park your ve-
hicle inside a garage or in a covered area.
When it is necessary to park outside, park in
a shady area or protect the vehicle with a
body cover.
Be careful not to scratch the paint sur-
face when putting on or removing the
body cover.
WASHING
Wash dirt off with a wet sponge and plenty
of water. Clean the vehicle thoroughly us-
ing a mild soap, a special vehicle soap or
general purpose dishwashing liquid mixed
with clean, lukewarm (never hot) water.
CAUTION
• Do not concentrate water spray di-
rectly on the sonar sensors (if so
equipped) on the bumper as this will
result in damage to the sensors. Do
not use pressure washers capable of
spraying water over 1,200 psi (8,274
kPa) to wash your vehicle. Use of
high-pressure washers over 1,200 psi
(8,274 kPa) can result in damage to or
removal of paint or graphics. Avoid
using a high-pressure washer closer
than 12 inches (30 cm) to the vehicle.
Always use a wide-angle nozzle only,
keep the nozzle moving and do not
concentrate the water spray on any
one area.
• Do not use car washes that use acid
in the detergent. Some car washes,
especially brushless ones, use some
acid for cleaning. The acid may react
with some plastic vehicle compo-
nents, causing them to crack. This
could affect their appearance, and
also could cause them not to func-
tion properly. Always check with your
car wash to confirm that acid is not
used. •
Do not wash the vehicle with strong
household soap, strong chemical de-
tergents, gasoline or solvents.
• Do not wash the vehicle in direct sun-
light or while the vehicle body is hot,
as the surface may become
water-spotted.
• Avoid using tight-napped or rough
cloths, such as washing mitts. Care
must be taken when removing
caked-on dirt or other foreign sub-
stances so the paint surface is not
scratched or damaged.
Rinse the vehicle thoroughly with plenty of
clean water.
Inside edges, seams and folds on the
doors, hatches and hood are particularly
vulnerable to the effects of road salt. There-
fore, these areas must be cleaned regularly.
Take care that the drain holes in the lower
edge of the door are open. Spray water
under the body and in the wheel wells to
loosen the dirt and wash away road salt.
A damp chamois can be used to dry the
vehicle to avoid water spots.
CLEANING EXTERIOR
7-2Appearance and care

CHROME PARTS
Clean all chrome parts regularly with a
non-abrasive chrome polish to maintain
the finish.
CAUTION
Do not use chrome cleaner on any
wheel. Doing so can damage the
chrome-like coating on the wheel.
TIRE DRESSINGS
NISSAN does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce discolor-
ation of the rubber. If a tire dressing is ap-
plied to the tires, it may react with the coat-
ing and form a compound. This compound
may come off the tire while driving and
stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:
• Use a water-based tire dressing. The coating on the tire dissolves more easily
than with an oil-based tire dressing.
• Apply a light coat of tire dressing to help prevent it from entering the tire tread/
grooves (where it would be difficult to re-
move). • Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is com-
pletely removed from the tire tread/
grooves.
• Allow the tire dressing to dry as recom- mended by the tire dressing manufac-
turer. Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or sof t bristled brush. Wipe
the vinyl and leather surfaces (if so
equipped) with a clean, sof t cloth damp-
ened in mild soap solution, then wipe clean
with a dry, sof t cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather (if so equipped).
Before using any fabric protector, read the
manufacturer's recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifi-
cation sensor (if so equipped). This can
also affect the operation of the air bag
system and result in serious personal
injury.
