Nissan Sentra Owners Manual: Tire Pressure Monitoring System (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and inflated
to the inflation pressure recommended 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 possible, and inflate
all your tires to the proper pressure. Driving on a
significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Underinflation
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 substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure, even if under-inflation has
not reached the level to
trigger illumination 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 combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately
one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Additional information:
- The TPMS does not monitor the tire
pressure of the spare tire.
- The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH
(25 km/h). Also, this system may not detect a
sudden drop in tire pressure (for example a
flat tire while driving).
- The low tire pressure warning light does not
automatically turn off when the tire pressure
of all your tires are adjusted. After the tires
are inflated to the recommended pressure,
the vehicle must be driven at speeds above
16 MPH (25 km/h) to activate the TPMS and
turn off the low tire pressure warning light.
Use a tire pressure gauge to check the tire
pressure.
- The CHECK TIRE PRESSURE warning
message is displayed in the odometer when
the low tire pressure warning light is illuminated
and low tire pressure is detected. The
CHECK TIRE PRESSURE warning message
turns off when the low tire pressure
warning light turns off. The low tire pressure
warning light remains illuminated until the
tires are inflated to the recommended COLD
tire pressure. The CHECK TIRE PRESSURE
warning message is displayed each
time the ignition switch is placed in the ON
position as long as the low tire pressure
warning light remains illuminated. See
“Check tire pressure warning message” in
the “Instruments and controls” section.
- The CHECK TIRE PRESSURE warning is
not displayed if the low tire pressure warning
light illuminates to indicate a TPMS malfunction.
- Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illuminate.
If the warning light illuminates, check
the tire pressure for all four tires.
- The Tire and Loading Information label (also
referred to as the vehicle placard or tire
inflation pressure label) is located in the
driver’s door opening.
For additional information, see “Low tire pressure
warning light” in the “Instruments and controls”
section and “Tire Pressure Monitoring System
(TPMS)” in the “In case of emergency” section.
WARNING
- Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufacturer
for the possible influences before
use.
- If the low tire pressure warning light
illuminates while driving, avoid sudden
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 underinflated
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 injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
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. (See “Flat tire” in the “In case
of emergency” section for changing a
flat 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 after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
- Replacing tires with those not originally
specified by NISSAN could affect 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 pressure
sensors.
|
CAUTION
Do not place metalized film or any metal
parts (antenna, etc.) on the windows. This
may cause poor reception of the signals
from the tire pressure sensors, and the
TPMS will not function properly.
Some devices and transmitters may temporarily
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.

TPMS with Easy Fill Tire Alert (if so
equipped)
When adding air to an under-inflated tire, the
TPMS with Easy Fill Tire Alert provides visual and
audible signals outside the vehicle to help you
inflate the tires to the recommended COLD tire
pressure.
Vehicle set-up:
- Park the vehicle in a safe and level place.
- Apply the parking brake and place the shift
lever into the P (Park) position (if so
equipped).
- Place the ignition switch to the ON position.
Do not start the engine.
Operation:
- Add air to the tire.
- After a few seconds, the hazard indicators
will start flashing.
- When the designated pressure is reached,
the horn beeps once and the hazard indicators
stop flashing.
- Perform the above steps for each tire.
- If the tire is over-inflated more than approximately
4 psi (30 kPa), the horn
beeps and the hazard indicators flash 3
times. To correct the pressure, push the
core of the valve stem on the tire briefly to
release pressure. When the pressure
reaches the designated pressure, the
horn beeps once.
- If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates that
the Easy Fill Tire Alert is not operating.
- The TPMS will not activate the Easy Fill
Tire Alert under the following conditions:
- If there is interference from an external
device or transmitter.
- The air pressure from the inflation device
is not sufficient to inflate the tire.
- There is a malfunction in the TPMS system.
- There is a malfunction in the horn or hazard
indicators.
- The identification code of the tires pressure
sensor is not registered to the system.
- The battery of the tire pressure sensor is
low.
- If the Easy Fill Tire Alert does not operate
due to TPMS interference, move the vehicle
about 3 ft (1 m) backward or forward
and try again.
If the Easy Fill Tire Alert is not working, use a tire
pressure gauge.
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
