2021 NISSAN TITAN warning light

If you have a flat tire, see “Flat tire”
(P. 6-3).
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely af-
fect electric medical equipment.
Those who use a pacemaker
should contact the electric medi-
cal equipment manufacturer for
the possible influences before
use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all four
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 infor-
mation 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 send-
ing a signal from a sensor that is
installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16
mph (25 km/h). Also, this system
may not detect a sudden drop in tire
pressure (for example a flat tire while
driving).
For additional information, see
“Warning lights, indicator lights and
audible reminders” (P. 2-12), “Tire
Pressure Monitoring System (TPMS)”
(P. 5-5), and “Flat tire” (P. 6-3).
Tire inflation pressure
Check the tire pressures (including
the spare) of ten and always prior to
long distance trips. The recom-
mended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S.
certification label or the Tire and
Loading Information label under the
“Cold Tire Pressure” heading. The Tire
and Loading Information label is af-
fixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
• Most tires naturally lose air over
time.
• Tires can lose air suddenly when driven over potholes or other ob-
jects or if the vehicle strikes a curb
while parking.
The tire pressures should be
checked when the tires are cold. The
tires are considered COLD af ter the
vehicle has been parked for 3 or
more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.The TPMS with Easy-Fill Tire Alert pro-
vides visual and audible signals out-
side the vehicle for inflating tires to
the recommended COLD tire pres-
sure. For additional information, see
“TPMS with Easy-Fill Tire Alert” (P. 5-7).

•Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is rec-
ommended that you visit a
NISSAN dealer for this service.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. Rec-
ommended types and sizes are shown in
“Wheels and tires” (P. 8-35).
WARNING
• The use of tires other than those rec-
ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the
ride, braking, handling, Vehicle Dy-
namic Control (VDC) system, 4WD,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speedom-
eter calibration, headlight aim and
bumper height. Some of these ef-
fects may lead to accidents and
could result in serious personal
injury.
• If your vehicle was originally
equipped with four tires that were
the same size and you are only re-
placing two of the four tires, install
the new tires on the rear axle. Placing
new tires on the front axle may cause
loss of vehicle control in some driving
conditions and cause an accident
and personal injury. •
If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad/shoe wear. For additional infor-
mation on wheel-off set dimensions,
see “Wheels and tires” (P. 10-9).
• 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 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
Do-it-yourself8-45

Your vehicle may be equipped with a full
size spare that is a different size or brand
than the tires originally installed on the ve-
hicle. This full size spare tire is intended for
temporary use only and should be re-
placed at the first opportunity.
Observe the following precautions if the
FULL SIZE TEMPORARY USE ONLY spare tire
must be used. Otherwise, your vehicle
could be damaged or involved in an acci-
dent:
WARNING
To help reduce the risk of a crash which
may result in personal injury or death:
• The TEMPORARY FULL SIZE spare tire
should be used for emergency use
only. It should be replaced with the
standard tire at the first opportunity
to avoid possible tire or differential
damage.
• Drive carefully while the TEMPORARY
FULL SIZE spare tire is installed. Avoid
sharp turns and abrupt braking while
driving. The vehicle driving perfor-
mance may be affected when driving
on wet or snow covered roads. •
When the TEMPORARY FULL SIZE
spare is installed, the following sys-
tems may not work correctly:
– Tire Pressure Monitoring System
(TPMS)
– Vehicle Dynamic Control (VDC)
System
• Periodically check the TEMPORARY
FULL SIZE spare tire inflation pres-
sure. Always keep the TEMPORARY
FULL SIZE inflated to the pressure
specification shown on the Tire and
Loading Information label.
• With the TEMPORARY FULL SIZE spare
tire installed do not drive the vehicle
at speeds faster than 50 mph (80
km/h).
• When driving on roads covered with
snow or ice, the TEMPORARY FULL
SIZE spare tire should be used on the
front wheels and the original tire
used on the rear wheels. Use tire
chains only on the drive wheels.
• Do not use the TEMPORARY FULL SIZE
spare tire on other vehicles.
• Do not use more than one TEMPO-
RARY FULL SIZE spare tire at the same
time. •
TEMPORARY FULL SIZE spare tire
Limitations (except for Pro 4X)
– 50mph MAX
– Towing allowed
• Customer can identif y TEMPORARY
FULL SIZE spare tire condition by
checking the Tire and loading infor-
mation label located on the B-pillar.
CAUTION
• Do not use tire chains on a TEMPO-
RARY FULL SIZE spare tire. Tire chains
will not fit properly and may cause
damage to the vehicle.
• Use of the TEMPORARY FULL SIZE
spare tire on a vehicle that has tires
larger than were originally equipped
can affect the 4WD system. This may
result in a circumference difference
between tires on front and rear axles
which can cause the 4WD system to
automatically place the vehicle in
2WD and flash the 4WD light. When
the TEMPORARY FULL SIZE spare tire
is replaces with a tire that matches all
other tires on the vehicle, and all tires
are properly inflated the 4WD system
will operate normally

Brakes:Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering system, such as excessive free-
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly. Windshield wiper and washer*:
Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery* (for maintenance free batter-
ies): For vehicles equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
Battery* (for serviceable batteries):
Check the fluid level in each cell. The fluid
should be at the bottom of the filler open-
ing. Vehicles operated in high tempera-
tures or under severe conditions require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the MIN and MAX lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
parking the vehicle on a level surface with
the engine off. Wait more than 10 minutes
for the oil to drain back into the oil pan.
9-4Maintenance and schedules

Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available
power-type module/converter must
be used to provide power for all trailer
lighting. This unit uses the vehicle bat-
tery as a direct power source for all
trailer lights while using the vehicle tail
light, stop light and turn signal circuits
as a signal source. The module/
converter must draw no more than 15
milliamps from the stop and tail lamp
circuits. Using a module/converter that
exceeds these power requirements
may damage the vehicle's electrical
system. See a reputable trailer retailer
to obtain the proper equipment and to
have it installed.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, it is recommended
that you contact a NISSAN dealer or repu-
table trailer retailer. Vehicles equipped with
the optional trailer tow package are
equipped with a 7-pin trailer harness con-
nector. If your trailer is equipped with a flat
4-pin connector, an adapter will be needed
to connect the trailer lights to the vehicle. Adapters are available at auto parts stores
and hitch retailers.Trailer brakes (if so equipped)
If your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is prop-
erly installed.
Vehicles equipped with a 7–pin trailer har-
ness connector are pre-wired for a trailer
brake controller. It is recommended that
you visit a NISSAN dealer for a trailer brake
adapter harness.
When towing a trailer load of 3,500 lbs.
(1587 kg) or more, trailers with a brake
system MUST be used.
However, most
states require a separate braking system
on trailers with a loaded weight above a
specific amount. Make sure the trailer
meets the local regulations and the regu-
lations where you plan to tow.
WARNING
The Gross Combined Weight Rating
(GCWR) must never exceed the vehicle
manufacturers recommendation.
Several types of braking systems are avail-
able. Surge Brakes -
The surge brake actuator is
mounted on the trailer tongue with a hy-
draulic line running to each trailer wheel.
Surge brakes are activated by the trailer
pushing against the hitch ball when the
tow vehicle is braking. Hydraulic surge
brakes are common on rental trailers and
some boat trailers. In this type of system,
there is no hydraulic or electric connection
for brake operation between the tow ve-
hicle and the trailer.
CAUTION
Your factory trailer brake control unit
will not activate surge-style trailer
brakes
Electric Trailer Brakes - Electric braking
systems are activated by an electronic sig-
nal sent from a trailer brake controller (spe-
cial brake-sensing module). If electric trailer
brakes are used, see “Electric trailer brake
controller" (P. 10-49).
Have a professional supplier of towing
equipment make sure the trailer brakes are
properly installed and demonstrate proper
brake function testing.
10-46Technical and consumer information

WARNING
Do not exceed Gross Combined Weight
Rating (GVWR). For additional informa-
tion about GVWR, see “Towing load/
specification” (P. 10-37).
Pre-towing tips
• Be certain your vehicle maintains a level position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
• Always secure items in the trailer to pre- vent load shif t while driving.
• Keep the cargo load as low as possible in the trailer to keep the trailer center of
gravity low.
• Load the trailer so approximately 60% of the trailer load is in the front half and 40%
is in the back half. Also make sure the load
is balanced side to side.
• Check your hitch, trailer tire pressure, ve- hicle tire pressure, trailer light operation,
and trailer wheel lug nuts every time you
attach a trailer to the vehicle.

This graphic shows the suggested boost levels for different trailer sizes relative to the vehicle size.
Technical and consumer information10-51

• Be certain your rearview mirrors conformto all federal, state or local regulations. 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 clearance
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
stability 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 inadver-
tently 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 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 selector 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
indicator light (if so
equipped) indicates the transfer case is
in 4H, 4LO, or 2H and that the ATP light is
off. If the
indicator light is flashing,
or the ATP light is ON, make sure the
transmission is in P (Park) (A/T) and turn
the 4WD switch to 2WD or 4H. For addi-
tional information, see “Automatic
transmission park warning light” (P. 2-13)
and “Using 4-wheel drive (4WD)” (P. 5-105).
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.
10-52Technical and consumer information

• While going downhill, the weight of thetrailer 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. 6-12).
• 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. • 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.
Trailer Sway Assist :
To minimize trailer sway, your vehicle may
apply braking to individual wheels based
on input from your vehicle sensors and ve-
hicle speed. Trailer sway control is a func-
tion of the Vehicle Dynamic Control (VDC)
system and is active when the VDC func-
tion is enabled.
CAUTION
If the VDC-OFF switch is on (meaning
VDC system OFF), the Trailer Sway As-
sist is also disabled
When Trailer Sway Assist is in operation, the
VDC warning light blinks. When vehicle con-
trol is regained, VDC warning light will turn
OFF.
For additional information about the VDC
system, see “Vehicle Dynamic Control (VDC)
OFF switch” (P. 2-57) and “Vehicle Dynamic
Control (VDC) system” (P. 5-118). If Trailer Sway Assist activates, do the fol-
lowing:
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
CAUTION
Do not try to 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. For additional information,
see “Pre-towing tips” (P. 10-51).
NOTE:
Trailer Sway Assist cannot reduce trailer
sway in all situations.
• 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.
