2018 NISSAN VERSA ECU

WARNING
∙ Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
∙ Properly secure all cargo to help pre-
vent it from sliding or shif ting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death.∙ If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
∙ Do not run the engine in closed spaces
such as a garage.
∙ Do not park the vehicle with the en-
gine running for any extended length
of time.
∙ Keep the rear vent windows, doors
and trunk lids (if so equipped) closed
while driving, otherwise exhaust
gases could be drawn into the pas-
senger compartment. If you must
drive with one of these open, follow
these precautions:
1. Open all the windows.
2. Turn the air recirculation mode off
and set the fan speed control to
the highest level to circulate the
air.
∙ The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.b. You suspect that exhaust fumes
are entering into the passenger
compartment.
c. You notice a change in the sound of
the exhaust system.
d. You have had an accident involving
damage to the exhaust system,
underbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
WARNING
∙ The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system
components.
∙ Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
PRECAUTIONS WHEN STARTING AND
DRIVING

2WD models with Continuously
Variable Transmission (CVT)
NISSAN recommends that your vehicle be
towed with the driving (front) wheels off the
ground or place the vehicle on a flatbed
truck as illustrated.
CAUTION
∙ Never tow CVT models with the front
wheels on the ground or four wheels
on the ground (forward or backward),
as this may cause serious and expen-
sive damage to the transmission. If it
is necessary to tow the vehicle with
the rear wheels raised always use
towing dollies under the front wheels.
∙ When towing CVT models with the
rear wheels on the ground or on tow-
ing dollies:– Place the ignition switch in the OFF
position, and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never

∙ Use only Genuine NISSAN floor mats,
or equivalent floor mats, that are spe-
cifically designed for use in your ve-
hicle model and model year.
∙ Properly position the mats in the
floorwell using the floor mat position-
ing hook. For additional information,
refer to "Floor mat installation" in this
section.
∙ Make sure the floor mat does not in-
terfere with pedal operation.
∙ Periodically check the floor mats to
make sure they are properly installed.
∙ Af ter cleaning the vehicle interior,
check the floor mats to make sure
they are properly installed.
The use of Genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.Floor mat installation
Your vehicle is equipped with floor mat po-
sitioning hook(s). The number and shape of
the floor mat positioning hooks for each
seating position varies depending on the
vehicle.
When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, the
shif t lever in P (Park) position (Continu-
ously Variable Transmission models) or
the shif t lever in the N (Neutral) position
(manual transmission models) and
with the parking break fully applied, po-
sition the floor mat in the floorwell so
that the floor mat grommet holes are
aligned with the hook(s).
2. Secure the grommet holes into the
hook(s) and ensure that the floor mat is
properly positioned.3. Make sure the floor mat does not inter-
fere with pedal operation. With the igni-
tion still in the OFF position, the shif t
lever in the P (Park) position (Continu-
ously Variable Transmission models) or
the shif t lever in the N (Neutral) position
(manual transmission models) and
with the parking break applied, fully ap-
ply and release all pedals. The floor mat
must not interfere with pedal opera-
tion or prevent the pedal from return-
ing to its normal position.
It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle.
7-6Appearance and care

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
∙ Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shif t lever
to N (Neutral). For CVT models, move
the shif t lever to P (Park).
∙ Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing any parts replacement or repairs.
∙ If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
∙ It is advisable to secure or remove any
loose clothing and remove any jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever
you work on your vehicle.∙ If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
∙ Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, sup-
port it with safety stands.
∙ Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
∙
Because the fuel lines on gasoline en-
gine models are under high pressure
even when the engine is off, it is recom-
mended that you visit a NISSAN dealer
for service of the fuel filter or fuel lines.

matic engine cooling fan. It may come
on at any time without warning, even
if the ignition key is in the OFF position
and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before work-
ing near the fan.
CAUTION
∙ Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.∙
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
