2020 NISSAN FRONTIER brakes

•If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC sys-
tem may not operate properly and
both the
and theindicator
lights may illuminate.
• If engine control related parts are not
NISSAN recommended or are ex-
tremely deteriorated, both the
andindicator lights may
illuminate.
• When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the
indicator
light may flash or theindicator
light may illuminate. Do not drive on
these types of roads.
• When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator light may
flash or theindicator light may
illuminate. This is not a malfunction.
Restart the engine af ter driving onto
a stable surface. •
If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not oper-
ate properly and the
indicator
light may flash or theindicator
light may illuminate.
• The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
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 helps
maintain vehicle speed when driving under
15-21 mph (25-35 km/h) on steeper down-
hill grades. Hill descent control is useful
when engine braking alone in 4H or 4L can-
not control vehicle speed. Hill descent con-
trol applies the vehicle brakes to control

vehicle speed allowing the driver to con-
centrate on steering while reducing the
burden of brake and accelerator operation.
• When additional braking is required onsteep downhill roads, activate the hill de-
scent control system by pushing the
switch on. For additional information, re-
fer to “Hill descent control switch” in the
“Instruments and controls” section of this
manual.
• Once the system is activated, the indica- tor light will remain on in the instrument
panel. For additional information, refer to
“Hill descent control system ON indicator
light” in the “Instruments and controls”
section of this manual.
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 2 (Second gear) or 1 (Low gear) for engine
braking.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.
Hill start assist will operate automatically
under the following conditions:
• The shif t lever is moved 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 moved to N (Neutral) or P (Park)
or on a flat and level road.

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 re-
garding brake inspections, refer to the ap-
propriate maintenance schedule informa-
tion in the "Maintenance and schedules"
section of this manual.
Two types of fuses are used. Type

tion frequently.
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*: Tires should be rotated ev-
ery 7,500 miles (12,000 km).
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.

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

Technical and consumer information10-29

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 3,500 lbs. (1,588 kg).
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 on and the doors
closed, allow the vehicle to stand for sev-
eral 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.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no
higher than the measured reference
height when the trailer is attached. If
the rear bumper is higher than the
measured reference height when
loaded, the vehicle may handle unpre-
dictably which could cause a loss of ve-
hicle control and cause serious per-
sonal injury or property damage.

Technical and consumer information10-31

Safety chains
Always use suitable safety chains between
your vehicle and the trailer. The safety chains
should be crossed and should be attached
to the hitch, not to the vehicle bumper or
axle. The safety chains can be attached to
the bumper if the hitch ball is mounted to the
bumper. Be sure to leave enough slack in the
chains to permit turning corners.
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 dealer
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 visit a NISSAN dealer or reputable
trailer dealer. Vehicles equipped with the
optional trailer tow package are equipped
with a 7-pin trailer harness connector. A flat
4–pin harness is available from your dealer
for vehicles without a tow package. If your
trailer is equipped with a flat 4-pin connec-
tor, an adapter will be needed to connect
the trailer lights to the vehicle. Adapters are
available at auto parts stores and hitch re-
tailers.
Trailer brakes
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.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system. 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.
Several types of braking systems are available.
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.
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, refer to “Electric trailer
brake controller" in this section.
Have a professional supplier of towing
equipment make sure the trailer brakes are
properly installed and demonstrate proper
brake function testing.
