2020 NISSAN ALTIMA engine

∙ When the climate system is in auto-matic operation and the engine coolant
temperature and outside air tempera-
ture are low, the air flow outlet may de-
fault to defroster mode for a maximum
of 2 minutes 30 seconds. This is not a
malfunction. Af ter the engine coolant
temperature warms up, the air flow out-
let will return to foot mode and opera-
tion will continue normally.
∙ When the outside and interior cabin temperatures are moderate to high, the
intake setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may oc-
cur when the previous climate setting
was turned off. This is not a malfunction.
Af ter the initial warm air is expelled, the
intake will return to automatic control,
the air flow outlet will return to previous
settings, and operation will continue
normally. To exit, press any climate con-
trol button.
∙ Keep the moonroof (if so equipped) closed while the air conditioner is in op-
eration. ∙ If you feel that the air flow mode you
have selected and the outlets the air is
coming out do not match, select
the
mode.
∙ When you change the air flow mode, you may feel air flow from the foot out-
lets for just a moment. This is not a
malfunction. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth’s ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, refer to “Air conditioner sys-
tem refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioner system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper
equipment.

WARNING
∙ Do not leave children or adults whowould 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.
∙ Closely supervise children when they are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; theycontain 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, lif tgates, doors and trunk lids (if so equipped)
closed while driving, otherwise ex-
haust gases could be drawn into the
passenger compartment. If you must
drive with one of these open, follow
these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
∙ If electrical wiring or other cable con- nections must pass to a trailer
through the seal on the trunk lid or the
body, follow the manufacturer’s rec-
ommendation to prevent carbon
monoxide entry into the vehicle. ∙ 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.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-4Starting and driving

∙ Do not stop or park the vehicle overflammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously re-
duce the three-way catalyst’s ability
to help reduce exhaust pollutants.
∙ Keep your engine tuned up. Malfunc- tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if no-
ticeable loss of performance or other
unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended that you
visit a NISSAN dealer for this service.
∙ Avoid driving with an extremely low fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
∙ Do not race the engine while warming it up. ∙ Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions
may occur for a variety of reasons, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale af ter replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

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-up1. 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.
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.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sen- sor is low.
5-8Starting and driving

NISSAN is committed to safe driving. How-
ever, you must choose not to drive under
the influence of alcohol. Every year thou-
sands of people are injured or killed in
alcohol-related collisions. Although the lo-
cal laws vary on what is considered to be
legally intoxicated, the fact is that alcohol
affects all people differently and most
people underestimate the effects of alco-
hol.
Remember, drinking and driving don’t mix!
That is true for drugs (over-the-counter,
prescription) and illegal drugs, too. Don’t
drive if your ability to operate your vehicle is
impaired by alcohol, drugs, or some other
physical condition.
DRIVING SAFETY PRECAUTIONS
Your NISSAN is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your NISSAN is
mainly designed for leisure use, unlike a
conventional off-road vehicle.
Remember that 2-Wheel Drive (2WD) mod-
els are less capable than All-Wheel Drive
(AWD) models for rough road driving and
extrication when stuck in deep snow or
mud, or the like.Please observe the following precautions:
WARNING
∙ Spinning the front wheels on slippery
surfaces may cause the AWD warning
message to display and the AWD sys-
tem to automatically switch from the
AWD to the 2WD mode. This could re-
duce the traction. Be especially care-
ful when towing a trailer (AWD
models).
∙ Drive carefully when off the road and avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving
over rough terrain.
∙ Do not drive across steep slopes. In- stead drive either straight up or
straight down the slopes. Off-road ve-
hicles can tip over sideways much
more easily than they can forward or
backward. ∙ Many hills are too steep for any ve-
hicle. If you drive up them, you may
stall. If you drive down them, you may
not be able to control your speed. If
you drive across them, you may roll
over.
∙ Do not shif t gears while driving on downhill grades as this could cause
loss of control of the vehicle.
∙ Stay alert when driving to the top of a hill. At the top there could be a drop-
off or other hazard that could cause
an accident.
∙ If your engine stalls or you cannot make it to the top of a steep hill, never
attempt to turn around. Your vehicle
could tip or roll over. Always back
straight down in R (Reverse) gear and
apply brakes to control your speed.
∙ Heavy braking going down a hill could cause your brakes to overheat and
fade, resulting in loss of control and
an accident. Apply brakes lightly and
use a low gear to control your speed.
