2020 NISSAN FRONTIER ignition

To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
– Rapidly push the push-button ignitionswitch three consecutive times in less
than 1.5 seconds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit, and the CHECK TIRE PRES (pres-
sure) warning message is displayed in the
odometer, one or more of your tires is sig-
nificantly under-inflated. If the vehicle is be-
ing driven with low tire pressure, the TPMS
will activate and warn you of it by the low
tire pressure warning light. This system will
activate only when the vehicle is driven at
speeds above 16 mph (25 km/h). For addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and Controls” section,
and “Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” section
of this manual.
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 the
light still illuminates while driving af-
ter adjusting the tire pressure, a tire
may be flat or the TPMS may be mal-
functioning. If you have a flat tire, re-
place it with a spare tire as soon as
possible. If no tire is flat and all tires
are properly inflated, have the ve-
hicle checked. It is recommended
that you visit a NISSAN dealer for this
service.

Two-Wheel Drive models with
automatic transmission
NISSAN recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flatbed
truck as illustrated.
CAUTION
• Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground
(forward or backward), as this may
cause serious and expensive dam-
age to the transmission. If it is neces-
sary to tow the vehicle with the front
wheels raised always use towing dol-
lies under the rear wheels.
• When towing automatic transmis-
sion models with the front wheels on
the ground or on towing dollies: –
Place the ignition switch in the
OFF position and secure the steer-
ing wheel in a straight-ahead po-
sition with a rope or similar de-
vice. Never secure the steering
wheel by placing the ignition
switch in the LOCK position. This
may cause damage to the steer-
ing lock mechanism (for models
with a steering lock mechanism).
NOTE:
If the battery is completely drained the
transmission will not manually shif t to
other positions.
VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
To avoid vehicle damage, serious per-
sonal injury or death when recovering a
stuck vehicle:
• Contact a professional towing ser-
vice to recover the vehicle if you have
any questions regarding the recov-
ery procedure.

•Properly position the mats in the
floorwell using the floor mat posi-
tioning hook. For additional informa-
tion, refer to "Floor mat installation"
in this section.
• Make sure the floor mat does not in-
terfere with pedal operation.
• Periodically check the floor mats to
make sure they are properly
installed.
• Af ter cleaning the vehicle interior,
check the floor mats to make sure
they are properly installed.
The use of Genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.
Floor mat installation
Your vehicle is equipped with floor mat po-
sitioning hook(s). The number and shape of
the floor mat positioning hooks for each
seating position varies depending on the
vehicle. When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, the
shif t lever in P (Park) position and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is
properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shif t le-
ver in the P (Park) position and with the
parking brake applied, fully apply and re-
lease all pedals. The floor mat must not
interfere with pedal operation or prevent
the pedal from returning to its normal
position.
It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle. The illustration shows the location of the
floor mat positioning hooks.
SEAT BELTS
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely in the shade before using them. For
additional information, refer to “Seat belt
maintenance” in the “Safety—Seats, seat
belts and supplemental restraint system”
section of this manual.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
• Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park).
