2021 NISSAN FRONTIER service

Your NISSAN is equipped with the
Bluetooth® Hands-Free Phone System. If
you have a compatible Bluetooth® enabled
cellular phone, you can set up the wireless
connection between your cellular phone
and the in-vehicle phone module. With
Bluetooth® wireless technology, you canmake or receive a hands-free telephone
call with your cellular phone in the vehicle.
Once your cellular phone is connected to
the in-vehicle phone module, no other
phone connecting procedure is required.
Your phone is automatically connected
with the in-vehicle phone module whenthe ignition switch is placed in the ON po-
sition with the connected cellular phone
turned on and carried in the vehicle.
You can register up to five different
Bluetooth® cellular phones to the in-
vehicle phone module. However, you can
talk on only one cellular phone at a time.
NISSAN Voice Recognition system sup-
ports the phone commands, so dialing a
phone number using your voice is possible.
For additional information, refer to “NISSAN
Voice Recognition System” in this section.
Before using the Bluetooth® Hands-Free
Phone System, refer to the following notes.
• Set up the wireless connection between
a cellular phone and the in-vehicle phone
module before using the hands-free
phone system.
• Some Bluetooth® enabled cellular phones may not be recognized by the
in-vehicle phone module. Please visit
www.nissanusa.com/bluetooth or
www.nissan.ca/bluetooth for a recom-
mended phone list and connecting in-
structions.
• You will not be able to use a hands-free phone under the following conditions:– Your vehicle is outside of the cellular service area.

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
EXHAUST GAS (carbon monoxide)air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the lif tgate or the
body, follow the manufacturer's rec-
ommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
• If a special body, camper, or other
equipment is added for recreational
or other usage, follow the manufac-
turer's recommendation to prevent
carbon monoxide entry into the ve-
hicle. Do not occupy these areas
while the engine is running even if
the vehicle is parked. Some recre-
ational vehicle appliances such as
stoves, refrigerators, heaters, etc.
may also generate carbon monoxide.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-2Starting and driving

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
CAUTION
• Do not use leaded gasoline. Deposits
from leaded gasoline will seriously
reduce the three-way catalyst's abil-
ity to help reduce exhaust pollutants. •
Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if no-
ticeable loss of performance or other
unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended that
you visit a NISSAN dealer for this
service.
• Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
• Do not race the engine while warm-
ing it up.
• Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,

WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
• If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light off. If you have
a flat tire, replace it with a spare tire
as soon as possible. For additional
information, refer to “Flat tire” in the
“In case of emergency ” section of this
manual for changing a flat tire. •
When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, 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 recommended 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.
• Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CAUTION
Do not place metalized film or any
metal parts (antenna, etc.) on the win-
dows. This may cause poor reception of
the signals from the tire pressure sen-
sors, and the TPMS will not function
properly. Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate.
Some examples are:
• Facilities or electric devices using similar
radio frequencies are near the vehicle.
• If a transmitter set to similar frequencies is being used in or near the vehicle.
• If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may
illuminate in the following cases:
• If the vehicle is equipped with a wheel and tire without TPMS.
• If the TPMS has been replaced and the ID has not been registered.
• If the wheel is not originally specified by NISSAN.

4. Gradually steer the vehicle to a safe lo-cation off the road and away from traffic
if possible.
5. Lightly apply the brake pedal to gradu- ally stop the vehicle.
6. Turn on the hazard warning flashers and contact a roadside emergency service
to change the tire. For additional infor-
mation, refer to “Changing a flat tire” in
the “In case of emergency” section of
this manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING

• If the SET indicator light blinks, turn theON•OFF switch off and have the system
checked. It is recommended that you visit
a NISSAN dealer for this service.
• The SET indicator light may blink when the ON•OFF switch is turned on while
pushing the ACCEL•RES, COAST•SET, or
CANCEL switch (located on the steering
wheel). To properly set the cruise control
system, use the following procedures.

• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• For vehicles equipped with
, use 4H
or 4L position only when necessary.
4-Wheel Drive operation lowers fuel
economy.
• Use the recommended viscosity engine oil. For additional information, refer to “En-
gine oil and oil filter recommendations” in
the “Technical and consumer informa-
tion” section of this manual.
CAUTION
• Do not drive the vehicle in the 4H or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces in
4H or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD warning light turns on
when you are driving on dry hard sur-
face roads:
– In the 4H position, shif t the 4WD
shif t switch to 2–Wheel Drive
(2WD).
– In the 4LO position for automatic
transmission vehicles, stop the
vehicle and shif t the shif t lever to
the N (Neutral) position with the
brake pedal depressed and shif t
the 4WD shif t switch to 2WD.
• If the warning light is still on af ter the
above operation, have your vehicle
checked as soon as possible. It is rec-
ommended that you visit a NISSAN
dealer for this service.

*1: Before moving the shif t lever from N (Neutral), wait until the transfer 4LO position indicator light stays on steady. This indicates that the 4WD shif t procedure
is completed and the transfer gear is correctly set in the 4LO position. If the vehicle is shif ted into gear before the indicator is on steady, the transf er gear
may grind, not engage correctly or stay in the neutral position.
- If the 4WD warning light illuminates, perform the following procedure to return the transfer case to correct operating condition.
1. Turn off the engine by placing the ignition switch in the OFF position.
2. Start the engine.
- Check that the 4WD warning light turns off. If the 4WD warning light illuminates, have the system checked. It is recommended that you visit a NISSAN dea ler
for this service.
3. Apply the parking brake, depress the brake pedal and move the shif t lever to N (Neutral) position.
4. With the brake pedal depressed, move the 4WD shif t switch to the desired mode.
- Be sure to wait until the transfer gear change completes before shif ting the shif t lever from the N (Neutral) position.
*2: While changing in and out of 4LO, the ignition switch must be in the ON position and the vehicle's engine must be running for a shif t to take place and for the indicator lights (4WD shif t and 4LO position indicator) to be operable. Otherwise, the shif t will not take place and no indicator lights will be on o r flashing.
*3: Make sure the transfer 4LO position indicator light turns on when you shif t the 4WD shif t switch to 4LO. The
indicator light will also turn on when 4LO
is selected. For additional information, refer to “Vehicle Dynamic Control (VDC) system” in this section.
When the 4LO position is selected, the VDC system is disabled and the VDC off indicator light illuminates, refer to “Vehicle Dynamic Control (VDC) off indicator
light” in the “Instruments and controls” section of this manual.
