2018 NISSAN VERSA brake sensor

Anti-lock Braking System (ABS) warning
indicator
When the parking brake is released and the
brake fluid level is sufficient, if both the
brake warning light and the ABS warning
light illuminate, it may indicate the ABS is
not functioning properly. Have the brake
system checked and, if necessary, repaired.
It is recommended that you visit a NISSAN
dealer for this service. Avoid high-speed
driving and abrupt braking. For additional
information, refer to “Anti-lock Braking Sys-
tem (ABS) warning light” in this section.
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, 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 engineimmediatelyand 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.
2-14Instruments and controls

– 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) 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 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 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.
5-26Starting and driving

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 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.
The VDC OFF switch is used to turn off the
VDC system. The
indicator illumi-
nates to indicate the VDC system is off.
When the VDC switch is used to turn off the
system, the VDC system still operates to

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.
∙ 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. 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 you have a
flat tire, replace it with a spare tire as
soon as possible.∙ Since the spare tire is not equipped
with the TPMS, 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 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 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 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.
