brakes NISSAN FRONTIER 2019 Owner´s Manual

WARNING
∙ Never rely solely on the hill start assistsystem to prevent the vehicle from
moving backward on a hill. Always
drive carefully and attentively. De-
press the brake pedal when the ve-
hicle is stopped on a steep hill. Be es-
pecially careful when stopped on a hill
on frozen or muddy roads. Failure to
prevent the vehicle from rolling back-
wards 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 conditions.
Always be prepared to depress the
brake pedal to prevent the vehicle
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.
WARNING
∙ Always turn and look back before backing up. The RSS is not a substi-
tute for proper backing procedures.
∙ Read and understand the limitations of the RSS as contained in this section.
Inclement weather may affect the
function of the RSS; this may include
reduced performance or a false
activation.
∙ This system is not designed to pre- vent contact with small or moving
objects.

CAUTION
∙ Af ter wiper blade replacement, returnthe wiper arm to its original position;
otherwise it may be damaged when
the hood is opened.
∙ Make sure the wiper blades contact the glass; otherwise the arms may be
damaged from wind pressure.
∙ Worn windshield wiper blades can damage the windshield and impair
driver vision.
If you wax the surface of the hood, be care-
ful not to let wax get into the windshield-
washer nozzle . This may cause clogging or
improper windshield-washer operation. If
wax gets into the nozzle, remove it with a
needle or small pin
1.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.

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.
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 5,000 miles (8,000 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. 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 vehicle
should pull to either side while driving on a
straight and level road, or if you detect un-
even or abnormal tire wear, there may be a
need for wheel alignment. If the steering
wheel or seat vibrates at normal highway
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.
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 catch or require uneven
effort. Keep the floor mat away from the
pedal.
Automatic transmission P (Park) mecha-
nism: On a fairly steep hill check that the
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. Keep the
floor mat away from the pedal.
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.

10-34Technical and consumer information

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
A, 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 sur- face. With the ignition on and the doors
closed, allow the vehicle 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 within 0 -
.5 inches (0 – 13 mm) of the reference
height measured in step 2. The rear
bumper should be no higher than the
reference height measured in step 2.

10-36Technical and consumer information

Tire pressures
∙ When towing a trailer, inflate thevehicle tires to the recom-
mended cold tire pressure indi-
cated on the Tire and Loading In-
formation label.
∙ Trailer tire condition, size, load rat- ing and proper inflation pressure
should be in accordance with the
trailer and tire manufacturer’s
specifications.
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 turn-
ing 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 repu-
table 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 di-
rectly 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 avail-
able.
10-38Technical and consumer information

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.
Electric trailer brake controller
Trailers equipped with electric brakes may
require the installation of an af termarket
trailer brake controller.A Genuine NISSAN jumper harness is avail-
able that is specifically designed to be used
when installing an af termarket brake con-
troller.
Install the af termarket electric trailer brake
controller according to the manufacturer’s
instructions.
Pre-towing tips
∙ Be certain your vehicle maintains a level
position when a loaded and/or un-
loaded trailer is hitched. Do not drive the
vehicle if it has an abnormal nose-up or
nose-down condition; check for im-
proper tongue load, overload, worn sus-
pension or other possible causes of ei-
ther condition.
∙ 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,
vehicle tire pressure, trailer light opera-
tion, and trailer wheel lug nuts every
time you attach a trailer to the vehicle.
∙ Be certain your rearview mirrors con- form to all federal, state or local regula-
tions. 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 clear-
ance 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 sta-
bility 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 in-
advertently becoming unlatched.
∙ Avoid abrupt starts, acceleration or stops.
∙ Avoid sharp turns or lane changes.
Technical and consumer information10-39

∙ Always drive your vehicle at a moderatespeed.
∙ 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 cor-
rections and back up slowly. If possible,
have someone guide you when you are
backing 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 lever to the P (Park)
position before blocking the wheels
and applying the parking brake, trans-
mission 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, 4L, 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
additional information, refer to “Auto-
matic transmission park warning light”
in the “Instruments and controls” sec-
tion and “Using 4-wheel drive (4WD)” in
the “Starting and driving” section of this
manual.
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. ∙ While going downhill, the weight of the
trailer 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
overheating. Shif ting to a lower gear in-
stead provides “engine braking” and re-
duces the need to brake as frequently.
∙ If the engine coolant temperature rises to a high temperature, refer to “If your
vehicle overheats” in the “In case of
emergency” section of this manual.
∙ 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 addi-
tional information, refer to “Mainte-
nance Schedules” in the “Maintenance
and schedules” section of this manual.
10-40Technical and consumer information

∙ When making a turn, your trailer wheelswill be closer to the inside of the turn
than your vehicle wheels. To compen-
sate 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
being passed by larger vehicles, be pre-
pared for possible changes in cross-
winds that could affect vehicle han-
dling.
Do the following if the trailer begins to
sway: 1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer
as straight ahead as the road condi-
tions allow. This combination will help
stabilize the vehicle
– Do not correct trailer sway by steer- ing or applying the brakes.
2. When the trailer sway stops, gently ap- ply 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 as described in this section. ∙ Be careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than nor-
mal passing. Remember, the length of
the trailer must also pass the other ve-
hicle before you can safely change
lanes.
∙ Downshif t the transmission 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 al- low for greater stopping distances
while towing a trailer. Anticipate stops
and brake gradually.
∙ NISSAN recommends that the cruise control not be used while towing a
trailer.
∙ Some states or provinces have specific regulations and speed limits for ve-
hicles 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, refer
to the “Do-it-yourself ” section in this
manual.
FLAT TOWING – 4WD WITH
AUTOMATIC TRANSMISSION
Towing a vehicle behind a recreational ve-
hicle, such as a motor home, is sometimes
called flat towing.
