Maintenance tire NISSAN ALTIMA 2020 Owner´s Manual

WARNING
∙ Af ter adjustment, release the adjust-ment button and try to move the
shoulder belt anchor up and down to
make sure it is securely fixed in
position.
∙ The shoulder belt anchor height should be adjusted to the position
best for you. Failure to do so may re-
duce the effectiveness of the entire
restraint system and increase the
chance or severity of injury in an
accident.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the
lap/shoulder belt and fasten it, an extender
that is compatible with the installed seat
belts is available for purchase. The ex-
tender adds approximately 8 in (200 mm)
of length and may be used for either the
driver or front passenger seating position.
It is recommended that you visit a NISSAN
dealer for assistance with purchasing an
extender if an extender is required.
WARNING
∙ Only NISSAN seat belt extenders,made by the same company which
made the original equipment seat
belts, should be used with NISSAN
seat belts.
∙ Adults and children who can use the standard seat belt should not use an
extender. Such unnecessary use
could result in serious personal injury
in the event of an accident.
∙ Never use seat belt extenders to in- stall child restraints. If the child re-
straint is not secured properly, the
child could be seriously injured or
killed in a collision or a sudden stop.
SEAT BELT MAINTENANCE
∙ To clean the seat belt webbing, apply
a mild soap solution or any solution rec-
ommended for cleaning upholstery or
carpet. Then wipe with a cloth and allow
the seat belts to dry in the shade. Do not
allow the seat belts to retract until they
are completely dry. ∙
If dirt builds up in the shoulder belt
guide of the seat belt anchors, the
seat belts may retract slowly. Wipe the
shoulder belt guide with a clean, dry
cloth.
∙ Periodically check to see that the seat
belt and the metal components, such
as buckles, tongues, retractors, flexible
wires and anchors, work properly. If
loose parts, deterioration, cuts or other
damage on the webbing is found, the
entire seat belt assembly should be re-
placed.

Maintenance
The maintenance menu allows the user to
set reminders for various vehicle mainte-
nance items.
WARNING
The tire replacement indicator is not a
substitute for regular tire checks, in-
cluding tire pressure checks. For addi-
tional information, refer to “Changing
wheels and tires” in the “Do-it-yourself ”
section of this manual. Many factors in-
cluding tire inflation, alignment, driving
habits and road conditions affect tire
wear and when tires should be re-
placed. Setting the tire replacement in-
dicator for a certain driving distance
does not mean your tires will last that
long. Use the tire replacement indicator
as a guide only and always perform
regular tire checks. Failure to perform
regular tire checks, including tire pres-
sure checks could result in tire failure.
Serious vehicle damage could occur
and may lead to a collision, which could
result in serious personal injury or
death.

∙ 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.
Starting and driving5-5

∙ Failure to operate this vehicle cor-rectly could result in loss of control
and/or a rollover accident.
∙ Always use tires of the same type, size, brand, construction (bias, bias-
belted, or radial), and tread pattern on
all four wheels. Install tire chains on
the front wheels when driving on slip-
pery roads and drive carefully.
∙ Be sure to check the brakes immedi- ately af ter driving in mud or water. For
additional information, refer to “Brake
precautions” in this section.
∙ Avoid parking your vehicle on steep hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured.
∙ Whenever you drive off-road through sand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. For additional
information, refer to “Maintenance
under severe operating conditions” in
the “Maintenance and schedules” sec-
tion of this manual.WARNING
Do not operate the push-button igni-
tion switch while driving the vehicle ex-
cept in an emergency. (The engine will
stop when the ignition switch is pushed
three consecutive times in quick suc-
cession or the ignition switch is pushed
and held for more than 2 seconds.) If the
engine stops while the vehicle is being
driven, this could lead to a crash and
serious injury.
When the ignition switch is pushed without
depressing the brake pedal, the ignition
switch will illuminate.
Push the ignition switch center:∙ Once to change to ON.
∙ Two times to change to OFF.
The ignition switch will automatically re-
turn to the LOCK position when any door is
either opened or closed with the switch in
the OFF position.

∙ Your vehicle will reach its ideal oper-ating temperature more quickly
while driving versus idling.
10. Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases
tire wear and lowers fuel economy.
∙ Keep the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual. If any malfunction occurs in the AWD sys-
tem while the engine is running, messages
are displayed in the meter.
