tires NISSAN SENTRA 2023 User Guide

Additional information:
• When using a wheel without the TPMSsuch as the spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
• The TPMS will activate only when the ve- hicle 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 is adjusted. Af ter
the tires are inflated to the recom-
mended 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 “Tire Pressure Low - Add Air” warning
message is displayed in the odometer
when the low tire pressure warning light
is illuminated and low tire pressure is de-
tected. The “Tire Pressure Low - Add Air”
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 “Tire Pressure Low - Add Air” warning
message is displayed each time the igni-
tion switch is placed in the ON position as
long as the low tire pressure warning light
remains illuminated.
• The “Tire Pressure Low - Add Air” 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 opera-
tion and the outside temperature. Do not
reduce the tire pressure af ter driving be-
cause the tire pressure rises af ter driving.
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 is
located in the driver's door opening.
For additional information, see “Tire Pres-
sure Low - Add Air ” (P. 2-29) or “Low tire
pressure warning light” (P. 2-13) “Tire Pres-
sure Monitoring System (TPMS)” (P. 6-3).
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.
5-6Starting and driving

•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 on changing a flat tire,
see “Flat tire” (P. 6-3). •
When using 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 reset as soon as pos-
sible. 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.

TPMS with Easy-Fill Tire Alert
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 theshif t lever in the P (Park) position (if so
equipped).
3. Place the ignition switch in the ON posi- tion. 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 thanapproximately 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 indicates
that the Easy-Fill Tire Alert is not
operating.
• The TPMS will not activate the Easy-Fill Tire Alert under the following condi-
tions:
– If there is interference from an ex- ternal 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 sensor is low.
• If the Easy-Fill Tire Alert does not oper- ate due to TPMS interference, move
the vehicle about 3 f t (1 m) backward
or forward and try again.
5-8Starting and driving

If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle.
As with any vehicle, loss of control could
result in a collision with other vehicles or
objects or cause the vehicle to roll over,
particularly if the loss of control causes
the vehicle to slide sideways.
Be attentive at all times, and avoid driving
when tired. Never drive when under the in-
fluence of alcohol or drugs (including pre-
scription or over-the-counter drugs which
may cause drowsiness). Always wear your
seat belt as outlined in the “Safety – Seats,
seat belts and supplemental restraint sys- tem” section of this manual, and also in-
struct your passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers.
In a rollover crash, an unbelted person is
significantly more likely to die than a
person wearing a seat belt.
OFF-ROAD RECOVERY
While driving, the right side or lef t side
wheels may unintentionally leave the road
surface. If this occurs, maintain control of
the vehicle by following the procedure be-
low. Please note that this procedure is only
a general guide. The vehicle must be driven
as appropriate based on the conditions of
the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering
wheel with both hands and try to hold a
straight course.
4. When appropriate, slowly release the ac- celerator pedal to gradually slow the
vehicle. 5. If there is nothing in the way, steer the
vehicle to follow the road while vehicle
speed is reduced. Do not attempt to
drive the vehicle back onto the road sur-
face until vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to
stay in the appropriate driving lane.
• If you decide that it is not safe to return the vehicle to the road surface based
on vehicle, road or traffic conditions,
gradually slow the vehicle to a stop in
a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving
on under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially
at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspecting the tires for wear and
damage. For additional information, see
Starting and driving5-9

“Wheels and tires” (P. 6-3). If a tire rapidly
loses air pressure or “blows-out” while driv-
ing, maintain control of the vehicle by fol-
lowing the procedure below. Please note
that this procedure is only a general guide.
The vehicle must be driven as appropriate
based on the conditions of the vehicle, road
and traffic.
WARNING
If there is a sudden loss of tire air pres-
sure, the vehicle will generally move or
pull in the direction of the flat tire. In
this situation, losing control of the ve-
hicle may cause a collision and result in
personal injury.
To help avoid loss of control:
• Do not rapidly apply the brakes.
• Do not rapidly release the accelerator
pedal.
• Do not rapidly turn the steering
wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a
straight course. 3. When appropriate, slowly release the ac-
celerator pedal to gradually slow the
vehicle.
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, see “Changing a flat tire” (P. 6-3 ).
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the blood-
stream reduces coordination, delays
reaction time and impairs judgement.
Driving af ter drinking alcohol increases
the likelihood of being involved in an
accident injuring yourself and others.
Additionally, if you are injured in an ac-
cident, alcohol can increase the sever-
ity of the injury. NISSAN is committed to safe driving. How-
ever, you must choose not to drive under
the influence of alcohol. Every year thou-
sands of people are injured or killed in
alcohol-related collisions. Although the lo-
cal laws vary on what is considered to be
legally intoxicated, the fact is that alcohol
affects all people differently and most
people underestimate the effects of
alcohol.
Remember, drinking and driving don't mix!
That is true for drugs (over-the-counter,
prescription) and illegal drugs, too. Don't
drive if your ability to operate your vehicle is
impaired by alcohol, drugs, or some other
physical condition.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake and clutch fluid (if so equipped),
and windshield-washer fluid as fre-
quently as possible, or at least whenever
you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Lock all doors.
• Position seat and adjust head restraints/headrests.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-9). 1. Apply the parking brake.
2.
Continuously Variable Transmission
model:
Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
if the shif t lever is in any of the driving
positions.
Manual Transmission (M/T) model:
Move the shif t lever to N (Neutral). De-
press the clutch pedal to the floor.
The starter is designed not to operate
unless the clutch pedal is fully
depressed.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and the
clutch pedal (if so equipped) and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the igni-
tion switch in any position.
BEFORE STARTING THE ENGINE STARTING THE ENGINE
5-14Starting and driving

•Always check your surroundings and
turn to check what is behind you be-
fore and while backing up. The RAB
system detects stationary objects
behind the vehicle. The RAB system
does not detect the following ob-
jects:
– Moving objects
– Low objects
– Narrow objects
– Wedge-shaped objects
– Objects close to the bumper (less
than approximately 1 f t [30 cm])
– Objects that suddenly appear
– Thin objects such as rope, wire,
chain, etc.
• The RAB system may not operate for
the following obstacles:
– Obstacles located high off the
ground
– Obstacles in a position offset from
your vehicle
– Obstacles, such as spongy materi-
als or snow, that have sof t outer
surfaces and can easily absorb a
sound wave •
The RAB system may not operate in
the following conditions:
– There is rain, snow, ice, dirt, etc.,
attached to the sonar sensors.
– A loud sound is heard in the area
around the vehicle.
– The surface of the obstacle is di-
agonal to the rear of the vehicle.
• The RAB system may unintentionally
operate in the following conditions:
– There is overgrown grass in the
area around the vehicle.
– There is a structure (e.g., a wall, toll
gate equipment, a narrow tunnel,
a parking lot gate) near the side of
the vehicle.
– There are bumps, protrusions, or
manhole covers on the road
surface.
– The vehicle drives through a
draped flag or a curtain.
– There is an accumulation of snow
or ice behind the vehicle.
– An ultrasonic wave source, such as
another vehicle’s sonar, is near
the vehicle. •
Once the automatic brake control
operates, it does not operate again if
the vehicle approaches the same
obstacle.
• The automatic brake control can only
operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
• In the following situations, the RAB
system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad
weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep
hill.
– The vehicle’s posture is changed
(e.g., when driving over a bump).
– The vehicle is driven on a slippery
road.
– The vehicle is turned sharply by
turning the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than NISSAN
recommended are used.
– The brakes are cold at low ambi-
ent temperatures or immediately
af ter driving has started.
5-90Starting and driving

– Vehicles where the tires are diffi-cult to see or the shape of the rear
of the vehicle is unclear or
obstructed.
– Parked vehicles.
• The AEB with Pedestrian Detection
system has some performance limi-
tations.
– If a stationary vehicle is in the ve-
hicle’s path, the system will not
function when the vehicle ap-
proaches the stationary vehicle at
speeds over approximately 50
mph (80 km/h).
– Pedestrian detection will not
function when the vehicle is
driven at speeds over approxi-
mately 37 mph (60 km/h) or below
approximately 6 mph (10km/h).
• For pedestrians, the AEB with Pedes-
trian Detection system will not issue
the first warning. •
The AEB with Pedestrian Detection
system may not function properly or
detect a vehicle or pedestrians
ahead in the following conditions:
– In poor visibility conditions (such
as rain, snow, fog, dust storms,
sand storms, smoke, and road
spray from other vehicles).
– If dirt, ice, snow, fog or other ma-
terial is covering the radar sensor
area or camera area of
windshield.
– If strong light (for example, sun-
light or high beams) enters the
front camera or a sudden change
in brightness occurs (for example,
entering a tunnel or driving in
lightning).
– In dark or dimly lit conditions,
such as at night or in tunnels, in-
cluding cases where your vehi-
cle’s headlights are off or dim, or
the tail lights of the vehicle ahead
are off.
– When the direction of the camera
is misaligned.
– When driving on a steep downhill
slope, on roads with sharp curves,
and/or bumpy or dirt roads.
– If there is interference by other ra-
dar sources. –
When your vehicle’s position or
movement is changed quickly or
significantly (for example, lane
change, turning vehicle, abrupt
steering, sudden acceleration or
deceleration).
– When your vehicle or the vehicle
or pedestrian ahead moves
quickly or significantly such that
the system cannot detect and re-
act in time (for example, pedes-
trian moving quickly toward the
vehicle at close range, vehicle cut-
ting in, changing lanes, making a
turn, steering abruptly, sudden
acceleration or deceleration).
– When the vehicle or pedestrian is
offset from the vehicle’s forward
path.
– If the speed difference between
the two vehicles is small.
– The pedestrian’s profile is par-
tially obscured or unidentifiable;
for example, due to transporting
luggage, pushing a stroller, wear-
ing bulky or very loose-fitting
clothing or accessories, or being
in a unique posture (such as rais-
ing hands).
5-98Starting and driving

7.Avoid Idling
• Shutting off your engine when safe for stops exceeding 30–60 seconds saves
fuel and reduces emissions
8. Buy an Automated Pass for Toll Roads
• Automated passes permit drivers to use special lanes to maintain cruising
speed through the toll and avoid stop-
ping and starting
9. Winter Warm Up
• Limit idling time to minimize impact to fuel economy
• Vehicles typically need no more than 30 seconds of idling at start-up to ef-
fectively circulate the engine oil before
driving
• Your vehicle will reach its ideal operat- ing temperature more quickly while
driving versus idling
10. Keeping your Vehicle Cool
• Park your vehicle in a covered parking area or in the shade whenever
possible
• When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system 11.
ECO Mode
• The ECO mode helps to enhance the fuel economy by controlling the en-
gine and Continuously Variable Trans-
mission (if so equipped) operation au-
tomatically to avoid rapid
acceleration. • Keep your engine tuned up.
• Follow the recommended scheduled
maintenance.
• 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.
• Use the recommended viscosity engine oil. For additional information, see “Engine
oil and oil filter recommendations”
(P. 10-7).
INCREASING FUEL ECONOMY
5-126Starting and driving

•Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
– When installing a spare tire, make
sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, see “Tire and
Loading Information label”
(P. 8-31).
– For additional information, see
“Wheels and tires” (P. 8-29).
The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The Anti-lock Braking System (ABS) in-
cludes electronic sensors, electric pumps,
hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature
that tests the system each time you start
the engine and move the vehicle at a low
speed in forward or reverse. When the self-
test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates the ABS warning light on the instrument panel. The brake system then
operates normally, but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds abov
e3-6mph(5-10
km/h). The speed varies according to road
conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion in the brake pedal and hear a noise
from under the hood or feel a vibration
from the actuator when it is operating. This
is normal and indicates that the ABS is op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
