2019 NISSAN SENTRA engine

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously re-
duce the three-way catalyst’s ability
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 warming 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,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion 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, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale af ter 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.

NOTE:
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user’s author-
ity to operate the equipment.
For Canada:
This device complies with Industry
Canada licence-exempt RSS standard(s).
Operation is subject to the following two
conditions: (1) this device may not cause
interference, and (2) this device must ac-
cept any interference, including interfer-
ence that may cause undesired opera-
tion of the device.
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 ve-
hicle to help you inflate the tires to the rec-
ommended COLD tire pressure.
Vehicle set-up:1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shif t lever in the P (Park) position (if so
equipped). 3. Place the ignition switch in the ON po-
sition. Do not start the engine.
Operation: 1. Add air to the tire.
2. Af ter a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. 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
three 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 af-
ter starting to inflate the tire, it indi-
cates that the Easy-Fill Tire Alert is
not operating. ∙ The TPMS will not activate the Easy-
Fill Tire Alert under the following con-
ditions:
– If there is interference from an exter- nal 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 tire’s pressure sensor is not registered to
the system.
– The battery of the tire pressure sen- sor is low.
∙ If the Easy-Fill Tire Alert does not op- erate due to TPMS interference, move
the vehicle about 3 f t (1 m) backward
or forward and try again.
If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.
