2018 NISSAN VERSA SEDAN sensor

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.

SYSTEM
5-26Starting 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. 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.
∙ 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 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.
In case of emergency6-3

CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
∙ Do not use a cleaner that uses strong
acid or alkali contents to clean the
wheels.
∙ Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as
ambient temperature.
∙ Rinse the wheel to completely remove
the cleaner within 15 minutes af ter
the cleaner is applied.
CHROME PARTS
Clean all chrome parts regularly with a
non-abrasive chrome polish to maintain
the finish.
TIRE DRESSINGS
NISSAN does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce discolor-
ation of the rubber. If a tire dressing is ap-
plied to the tires, it may react with the coat-
ing and form a compound. This compound
may come off the tire while driving and
stain the vehicle paint.If you choose to use a tire dressing, take the
following precautions:
∙ Use a water-based tire dressing. The
coating on the tire dissolves more easily
than with an oil-based tire dressing.
∙ Apply a light coat of tire dressing to help
prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove).
∙ Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is
completely removed from the tire
tread/grooves.
∙ Allow the tire dressing to dry as recom-
mended by the tire dressing manufac-
turer.Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or sof t bristled brush. Wipe
the vinyl and leather (if so equipped) sur-
faces with a clean, sof t cloth dampened in
mild soap solution, then wipe clean with a
dry, sof t cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather (if so equipped).
Before using any fabric protector, read the
manufacturer’s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifi-
cation sensor. This can also affect the
operation of the air bag system and re-
sult in serious personal injury.
CLEANING INTERIOR
7-4Appearance and care

Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, refer to “Jump
starting” in the “In case of emergency” sec-
tion of this manual. If the engine does not
start by jump starting, the battery may
have to be replaced. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
CAUTION
∙ Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
∙ Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
Your vehicle is equipped with a variable
voltage control system. This system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator.The current sensor
Ais located near the
battery along the negative battery cable. If
you add electrical accessories to your ve-
hicle, be sure to ground them to a suitable
body ground such as the frame or engine
block area.

∙ 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 one minute. The light will
remain on af ter one minute. Have
your tires replaced and/or TPMS sys-
tem reset as soon as possible. It is rec-
ommended that you visit a NISSAN

∙ Replacing tires with those not origi-
nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
∙ When replacing the TPMS sensor, the
ID registration may be required. Con-
tact a NISSAN dealer for ID
registration.
∙ Do not use a valve stem cap that is not
specified by NISSAN. The valve stem
cap may become stuck.
∙ Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of
pressure.∙ Do not install a damaged or deformed
wheel or tire even if it has been re-
paired. Such wheels or tires could
have structural damage and could fail
without warning.
∙ The use of retread tires is not
recommended.
∙ For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. It is recom-
mended that you visit a NISSAN dealer for
this service.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
∙For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Care of wheels
∙ Wash the wheels when washing the ve-
hicle to maintain their appearance.
∙ Clean the inner side of the wheels when
the wheel is changed or the underside
of the vehicle is washed.
∙ Do not use abrasive cleaners when
washing the wheels.
∙ Inspect wheel rims regularly for dents
or corrosion. Such damage may cause
loss of pressure or poor seal at the tire
bead.
∙ NISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.

WARNING
∙ The front air bags ordinarily will notinflate in the event of a side impact,
rear impact, rollover, or lower severity
frontal collision. Always wear your
seat belts to help reduce the risk or
severity of injury in various kinds of
accidents
∙ The front passenger air bag will not inflate if the passenger air bag status
light is lit or if the front passenger seat
is unoccupied. For additional infor-
mation, refer to “Front passenger air
bag and status light” in this section. ∙ The seat belts and the front air bags
are most effective when you are sit-
ting well back and upright in the seat.
The front air bags inflate with great
force. Even with the NISSAN Advanced
Air Bag System, if you are unre-
strained, leaning forward, sitting side-
ways or out of position in any way, you
are at greater risk of injury or death in
a crash. You may also receive serious
or fatal injuries from the front air bag
if you are up against it when it inflates.
Always sit back against the seatback and as far away as practical from the
steering wheel or instrument panel.
Always properly use the seat belts.
∙ The driver and front passenger seat belt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The NISSAN Advanced Air
Bag System monitors the severity of a
collision and seat belt usage, then in-
flates the air bags as needed. Failure
to properly wear seat belts can in-
crease the risk or severity of injury in
an accident.
∙ The front passenger seat is equipped with an occupant classification sen-
sor (weight sensor) that turns the
front passenger air bag OFF under
some conditions. This sensor is only
used in this seat. Failure to be properly
seated and wearing the seat belt can
increase the risk or severity of injury in
an accident. For additional informa-
tion, refer to “Front passenger air bag
and status light” in this section.
∙ Keep hands on the outside of the steering wheel. Placing them inside
the steering wheel rim could increase
the risk that they are injured when the
front air bag inflates.
