2020 NISSAN FRONTIER warning light

WARNING
• Tires should be periodically in-
spected for wear, cracking,
bulging or objects caught in
the tread. If excessive wear,
cracks, bulging or deep cuts
are found, the tire(s) should be
replaced.
• The original tires have built-in
tread wear indicators. When
the wear indicators are visible,
the tire(s) should be replaced.
• Tires degrade with age and
use. Have tires, including the
spare, over 6 years old checked
by a qualified technician be-
cause some tire damage may
not be obvious. Replace the
tires as necessary to prevent
tire failure and possible per-
sonal injury. •
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. For ad-
ditional information, refer to “Wheels and
tires” in the “Technical and consumer infor-
mation” section of this manual.
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, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects
may lead to accidents and could re-
sult 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.
Do-it-yourself8-39

•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 wear. For additional information
on wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical
and consumer information” section
of this manual.
• When replacing 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.
• When replacing the TPMS sensor, the
ID registration may be required. It is
recommended that you visit a
NISSAN dealer for ID registration.
• Do not use a valve stem cap that is
not specified by NISSAN. The valve
stem cap may become stuck.
• Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of
pressure.
• Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.Four-wheel drive models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer
case and differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. It is recom-
mended that you visit a NISSAN dealer for
this service.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.

10-14Technical and consumer information

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.

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 addi-
tional information, refer to “Automatic
transmission park warning light” in the
“Instruments and controls” section and
“Using 4-wheel drive (4WD)” in the “Start-
ing 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 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, refer to “If your ve-
hicle overheats” in the “In case of emer-
gency” 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 additional
information, refer to “Maintenance
Schedules” in 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.
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 conditions
allow. This combination will help stabilize
the vehicle
– Do not 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.
Technical and consumer information10-35

WARNING
A vehicle equipped with Four-Wheel
Drive (4WD) should never be tested us-
ing a two wheel dynamometer (such as
the dynamometers used by some
states for emissions testing), or similar
equipment. Make sure you inform the
test facility personnel that your vehicle
is equipped with 4WD before it is placed
on a dynamometer. Using the wrong
test equipment may result in transmis-
sion damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” for an Inspection/
Maintenance (I/M) test of the emission
control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the ready condition can
be obtained by ordinary usage of the ve-
hicle. If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready ” condi-
tion. Before taking the I/M test, check the
vehicle's inspection/maintenance test
readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds, the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready ”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a ve-
hicle's systems performed. The EDR is de-
signed to record data related to vehicle dy-
namics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to re-
cord such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
• How fast the vehicle was traveling.
• Sounds are not recorded.
