2015 NISSAN SENTRA sensor

●If you need to dispose of the supple-
mental air bag or pretensioner systems
or scrap the vehicle, contact a NISSAN
dealer. Incorrect disposal procedures
could cause personal injury.
● If there is an impact to your vehicle from
any direction, your Occupant Classifica-
tion Sensor (OCS) should be checked
by a NISSAN dealer to verify it is still
functioning correctly. The OCS should
be checked even if no air bags deploy as
a result of the impact. Failure to verify
proper OCS function may result in an
improper air bag deployment resulting
in injury or death.
NOTE:
In the event of a crash involving an air bag
deployment (side, front or both) , the vehi-
cle’s hazard lamps (turn indicators) will ac-
tivate.

Autolight system (if so equipped)
The autolight system allows the headlights to be
set so they turn on and off automatically. The
autolight system can:● Turn on the headlights, front parking, tail,
license plate and instrument panel lights au-
tomatically when it is dark.
● The autolight system will turn on if the wind-
shield wipers make four continuous passes
(USA only) .
● Turn off all the lights when it is light. ●
Keep all the lights on a period of time after
you turn the key to OFF and all doors are
closed.
To turn on the autolight system: 1. Turn the headlight switch to the AUTO posi- tion
1.
2. Turn the ignition key to ON.
3. The autolight system automatically turns the headlights on and off.
Initially, if the ignition switch is turned OFF and a
door is opened and left open, the headlights
remain ON for a period of time. If another door is
opened while the headlights are on, then the
timer is reset.
To turn the autolight system off, turn the switch to
the OFF,
,orposition.
Be sure you do not put anything on top of
the autolight sensor located in the top side
of the instrument panel. The autolight sen-
sor controls the autolight; if it is covered,
the autolight sensor reacts as if it is dark
out and the headlights will illuminate. If
this occurs while parked with the engine off
and the key in the ON position, your vehi-
cle’s battery could become discharged.

The sunload sensor (if so equipped) , located on
the top passenger’s side of the instrument panel,
helps the system maintain a constant tempera-
ture. Do not put anything on or around this sen-
sor.The air conditioner system in your NISSAN ve-
hicle is charged with a refrigerant designed with
the environment in mind.
This refrigerant does not harm the earth’s
ozone layer.
Special charging equipment and lubricant is re-
quired when servicing your NISSAN air condi-
tioner. Using improper refrigerants or lubricants
will cause severe damage to your air conditioner
system. For additional information, refer to “Air
conditioner system refrigerant and oil recommen-
dations” in the “Technical and consumer informa-
tion” section of this manual.
A NISSAN dealer is able to service your “environ-
mentally friendly” air conditioning system.
WARNING
The air conditioner system contains refrig-
erant under high pressure. To avoid per-
sonal injury, any air conditioner service
should be done only by an experienced
technician with proper equipment.
RADIO
With the ignition placed in the ACC or ON posi-
tion, press the PWR (power)/VOL (volume) knob
to turn the radio on. If you listen to the radio with
the engine not running, the ignition should be
placed in the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external influ-
ences. Intermittent changes in reception quality
normally are caused by these external influences.
Using a cellular phone in or near the vehicle
may influence radio reception quality.
Radio reception
Your NISSAN radio system is equipped with
state-of-the-art electronic circuits to enhance ra-
dio reception. These circuits are designed to
extend reception range, and to enhance the qual-
ity of that reception.
However, there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle, even
when the finest equipment is used. These char-
acteristics are completely normal in a given re-
ception area and do not indicate any malfunction
in your NISSAN radio system.

●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 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 pressure
shown on the Tire and Loading Informa-
tion 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 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 a 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 illu-
minate.
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. FCC Notice:

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:1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shift lever into the P (Park) position (if so
equipped) .
3. Place the ignition switch to the ON position. Do not start the engine.
Operation: 1. Add air to the tire.
2. After a few seconds, the hazard indicators will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard indica-
tors stop flashing.
4. Perform the above steps for each tire. ●If the tire is over-inflated more than ap-
proximately 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 haz- ard indicators.
–
The identification code of the tires pres-
sure 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 ve-
hicle 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.
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 ma-
neuvers, 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 influence of
alcohol or drugs (including prescription or over-
the-counter drugs which may cause drowsi-
ness) . Always wear your seat belt as outlined in
the “Safety – Seats, seat belts and supplemental
restraint system” section of this manual, and also
instruct your passengers to do so.
5-6Starting and driving

– When installing a spare tire, makesure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, refer to the ”Tire and load-
ing information label” in the “Techni-
cal and consumer information”
section of this manual.
– For additional information, refer to “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking on
slippery surfaces. The system detects the rota-
tion speed at each wheel and varies the brake
fluid pressure to prevent each wheel from locking
and sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain steering
control and helps to minimize swerving and spin-
ning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate 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 ABS includes 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
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates 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 vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates at speeds above3-6mph(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 ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation 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 operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional brake booster even with light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. it is the driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all times.
