2021 NISSAN TITAN brake light

WARNING
• Never rely solely on the hill descent
control system to control vehicle
speed when driving on steep down-
hill grades. Always drive carefully and
attentively when using the hill de-
scent control system and decelerate
the vehicle speed by depressing the
brake pedal if necessary. Be espe-
cially careful when driving on frozen,
muddy or extremely steep downhill
roads. Failure to control vehicle
speed may result in a loss of control
of the vehicle and possible serious
injury or death.
• The hill descent control may not con-
trol the vehicle speed on a hill under
all load or road conditions. Always be
prepared to depress the brake pedal
to control vehicle speed. Failure to do
so may result in a collision or serious
personal injury. The hill descent control system can only be
activated when the 4H or 4LO position is
engaged.
The hill descent control system helps
maintain vehicle speed when driving under
15 mph (25 km/h) on steeper downhill
grades. Hill descent control is useful when
engine braking alone cannot control ve-
hicle speed. Hill descent control applies the
vehicle brakes to control vehicle speed al-
lowing the driver to concentrate on steer-
ing while reducing the burden of brake and
accelerator operation.
If the hill descent control system ON indica-
tor light is blinking, the hill descent control
is engaged; however, the hill descent con-
trol will not control the vehicle speed.
• Once the system is activated, the indica-
tor light will remain on in the instrument
panel. For additional information, see “Hill
descent control system ON indicator
light” (P. 2-18).
• You may hear a noise from under the hood or feel a vibration from the actuator
when it is operating. This indicates that
the hill descent control system is working
properly. If the accelerator or brake pedal is de-
pressed while the hill descent control sys-
tem is on, the system will stop operating
temporarily. As soon as the accelerator or
brake pedal is released, the hill descent
control system begins to function again if
the hill descent control operating condi-
tions are fulfilled.
For the best results, when descending
steep downhill grades, the hill descent con-
trol switch should be ON and the shif t lever
in M1 (First) for engine braking. For addi-
tional information, see “Hill descent control
switch” (P. 2-58).

WARNING
• Never rely solely on the hill start as-
sist system to prevent the vehicle
from moving backward on a hill. Al-
ways drive carefully and attentively.
Depress the brake pedal when the
vehicle is stopped on a steep hill. Be
especially careful when stopped on a
hill on frozen or muddy roads. Failure
to prevent the vehicle from rolling
backwards may result in a loss of
control of the vehicle and possible
serious injury or death.
• The hill start assist system is not de-
signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and
may result in a collision or serious
personal injury.
• The hill start assist may not prevent
the vehicle from rolling backwards
on a hill under all load or road condi-
tions. Always be prepared to depress
the brake pedal to prevent the ve-
hicle from rolling backwards. Failure
to do so may result in a collision or
serious personal injury. When the vehicle is stopped on a hill, the hill
start assist system automatically keeps
the brakes applied. This helps prevents the
vehicle from rolling backward in the time it
takes the driver to release the brake pedal
and apply the accelerator when the vehicle
is stopped on a hill.
Hill start assist will operate automatically
under the following conditions:
• The shif t lever is shif ted to a forward or
reverse gear.
• The vehicle is stopped completely on a hill by applying the brake.
The maximum holding time is 2 seconds.
Af ter 2 seconds the vehicle will begin to roll
back and hill start assist will stop operating
completely.
Hill start assist will not operate when the
shif t lever is shif ted into N (Neutral) or P
(Park) or on a flat and level road. When the
indicator light illuminates in the meter,
the hill start assist system will not operate. The front and rear sonar system sounds a
tone to inform the driver of obstacles near
the bumper.
When the “DISPLAY” key is ON, the sonar
view will automatically appear in the meter.WARNING
• The front and rear sonar system is a
convenience but it is not a substitute
for proper parking.

WARNING
• Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake system.
The use of improper fluids can dam-
age the brake system and affect the
vehicle's stopping ability.
• Clean the filler cap before removing.
• Brake fluid is poisonous and should
be stored carefully in marked con-
tainers out of reach of children.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid
is spilled, immediately wash the sur-
face with water.
Check the fluid level in the reservoir. If the
brake fluid is below the MIN line
OB, the
brake warning light will illuminate. Add
brake fluid up to the MAX line
OA. For addi-
tional information on recommended type
of brake fluid, see “Recommended fluids/
lubricants and capacities” (P. 10-2).
If the brake fluid must be added frequently,
the brake system should be thoroughly
checked. It is recommended that you visit a

Be careful not to let anything get into the
washer nozzle
OD. This may cause clogging
or improper windshield–washer operation.
If something gets into the nozzle, remove it
with a needle or small pin
OC. If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-
adjust every time the brake pedal is ap-
plied.
WARNING
Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended that you
visit a NISSAN dealer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched
scraping or screeching sound will be heard
when the vehicle is in motion. The noise will
be heard whether or not the brake pedal is
depressed. Have the brakes checked as
soon as possible if the wear indicator
sound is heard. Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information on
the appropriate maintenance schedule re-
garding brake inspections, see "Mainte-
nance schedules" (P. 9-7).LDI2710

•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.

Doors and engine hood:Check that the
doors and engine hood operate properly.
Also ensure that all latches lock securely.
Lubricate hinges, latches, latch pins, rollers
and links if necessary. Make sure that the
secondary latch keeps the hood from
opening when the primary latch is re-
leased.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch in a fully open position. If the hood,
trunk, or rear hatch is not held open, have
the gas stays or struts replaced.
Lights*: Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Rotate tires at the specified
interval shown in the maintenance sched-
ule. Tires*:
Check the pressure with a gauge
of ten and always prior to long distance
trips. If necessary, adjust the pressure in all
tires, including the spare, to the pressure
specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the
TPMS transmitter grommet seal, valve core
and cap when the tires are replaced due to
wear or age.
Wheel alignment and balance: If the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may
be a need for wheel alignment. If the steer-
ing wheel or seat vibrates at normal high-
way speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield: Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility. It is recom-
mended that you have a damaged wind- shield repaired by a NISSAN dealer, or a
NISSAN Certified Collision Center. To locate
a collision center in your area, refer to
http://collision.nissanusa.com.
Windshield wiper blades*:
Check for
cracks or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled maintenance,
cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the
pedal does not bind or require uneven ef-
fort. Keep the floor mat away from the
pedal.
Automatic transmission P (Park) posi-
tion mechanism: On a fairly steep hill
check that your vehicle is held securely
with the shif t lever in the P (Park) position
without applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service.
