2019 NISSAN VERSA SEDAN brake sensor

WARNING
∙ Your brake system may not be work-ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for repairs.
Otherwise, have your vehicle towed
because driving it could be
dangerous.
∙ Pressing the brake pedal with the en- gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.
∙ If the brake fluid level is below the MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked. It is
recommended that you visit a NISSAN
dealer for this service.
Charge warning light
If this light comes on while the engine is
running, it may indicate the charging sys-
tem is not functioning properly. Turn the
engine off and check the generator belt. If
the belt is loose, broken, or missing, or if the
light remains on, have the system checked. It is recommended that you visit a NISSAN
dealer for this service.
CAUTION
∙ Do not ground electrical accessories
directly to the battery terminal. Doing
so will bypass the variable voltage
control system and the vehicle bat-
tery may not charge completely. For
additional information, refer to “Vari-
able voltage control system” in the
“Do-it-yourself ” section of this
manual.
∙ Do not continue driving if the genera- tor belt is loose, broken or missing.
Door open warning light
This light comes on when any of the doors
are not closed securely while the ignition
switch is in the ON position.
Engine oil pressure
warning light
This light warns of low engine oil pressure. If
the light flickers or comes on during nor-
mal driving, pull off the road in a safe area,
stop the engine immediatelyand call a
NISSAN dealer or other authorized repair
shop. The engine oil pressure warning light is
not designed to indicate a low oil level.
Use the dipstick to check the oil level. For
additional information, refer to “Engine oil”
in the “Do-it-yourself ” section of this
manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by the NISSAN New Vehicle Limited
Warranty. Turn off the engine as soon as
it is safe to do so.
High temperature warning
light (red) (if so equipped)
When the ignition switch is placed in the ON
position, the high temperature warning
light illuminates and then turns off. This in-
dicates that the high temperature sensor
in the engine coolant system is opera-
tional.
When driving, the high temperature warn-
ing light may turn off. This indicates that the
engine coolant temperature is within the
normal range.

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 thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash three times. To correct the pres-
sure, push the core of the valve stem
on the tire briefly to release pressure.
When the pressure reaches the des-
ignated 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.
5-6Starting 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, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” section of this manual.
– For additional information, refer to “Wheels and tires” in the “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 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) 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 for-
ward 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 malfunction, it switches
the ABS off and illuminates the ABS warning
light on the instrument panel. The brake sys-
tem 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.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.
Starting and driving5-31

WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.The VDC system uses various sensors to
monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC
system helps to perform the following
functions:
∙ Controls brake pressure to reduce wheel slip on one slipping drive wheel
so power is transferred to a non-
slipping drive wheel on the same axle.
∙ Controls brake pressure and engine output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).
∙ Controls brake pressure at individual wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
– Understeer (vehicle tends to not fol- low the steered path despite in-
creased steering input)
– Oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to
maintain control of the vehicle, but it can-
not prevent loss of vehicle control in all driv-
ing situations. When the VDC system operates, theindicator light in the instrument panel
flashes so note the following:
∙ The road may be slippery or the system may determine some action is required
to help keep the vehicle on the steered
path.
∙ You may feel a pulsation in the brake pedal and hear a noise or vibration from
under the hood. This is normal and indi-
cates that the VDC system is working
properly.
∙ Adjust your speed and driving to the road conditions.
For additional information, refer to “Slip in-
dicator light” and “Vehicle Dynamic Control
(VDC) OFF indicator light” in the ”Instru-
ments and controls” section of this manual.
If a malfunction occurs in the system,
the
indicator light comes on in the
instrument panel. The VDC system auto-
matically turns off when this indicator light
is on.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-32Starting and driving

∙ If the low tire pressure warning lightilluminates 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. Driv-
ing with under-inflated tires may per-
manently damage the tires and in-
crease 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 Infor-
mation label to turn the low tire pres-
sure warning light OFF. If the light still
illuminates while driving af ter adjust-
ing the tire pressure, a tire may be flat
or the TPMS may be malfunctioning. If
you have a flat tire, replace it with a
spare tire as soon as possible. If no tire
is flat and all tires are properly in-
flated, have the vehicle checked. It is
recommended that you visit a NISSAN
dealer for this service. ∙ When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for these services.
∙ 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.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road and away from traffic.
2. Turn on the hazard warning flashers. 3. Park on a level surface and apply the
parking brake. Shif t the manual trans-
mission into R (Reverse) or the Continu-
ously Variable Transmission (CVT) into
P (Park).
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assis-
tance personnel that you need assis-
tance.
6. Have all passengers get out of the ve- hicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
∙ Make sure the parking brake is se-curely applied and the manual trans-
mission is shif ted into R (Reverse), or
the Continuously Variable Transmis-
sion (CVT) into P (Park).
∙ Never change tires when the vehicle is on a slope, ice or slippery areas. This is
hazardous.
∙ Never change tires if oncoming traffic is close to your vehicle. Wait for pro-
fessional road assistance.
