2020 NISSAN ALTIMA spare wheel

∙ When replacing a wheel without theTPMS 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.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
CAUTION
∙ The TPMS is not a substitute for theregular tire pressure check. Be sure to
check the tire pressure regularly.
∙ If the vehicle is being driven at speeds of less than 16 mph (25 km/h), the
TPMS may not operate correctly.
∙ Be sure to install the specified size of tires to the four wheels correctly.
Master warning light
When the ignition is in the ON position, the
master warning light illuminates if any of
the following are displayed on the vehicle
information display.
∙ No key warning
∙ Low windshield-washer fluid warning
∙ Parking brake release warning
∙ Door/trunk open warning
∙ Loose fuel cap
∙ Low tire pressure warning
Power steering warninglight
WARNING
∙ If the engine is not running or is turned off while driving, the power as-
sist for the steering will not work.
Steering will be harder to operate. ∙ When the power steering warning
light illuminates with the engine run-
ning, there will be no power assist for
the steering. You will still have control
of the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
When the ignition switch is placed in the ON
position, the power steering warning light
illuminates. Af ter starting the engine, the
power steering warning light turns off. This
indicates the power steering is operational.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering is not function-
ing properly and may need servicing. Have
the power steering checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
When the power steering warning light illu-
minates with the engine running, there will
be no power assist for the steering, but you
will still have control of the vehicle. At this
time, greater steering effort is required to
operate the steering wheel, especially in
sharp turns and at low speeds.
2-14Instruments and controls

∙ 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

Additional information:∙ When replacing a wheel without the TPMS such as the spare tire, the TPMS
does not monitor the tire pressure of
the spare tire.
∙ The TPMS will activate only when the vehicle is driven at speeds above
16 mph (25 km/h). Also, this system may
not detect a sudden drop in tire pres-
sure (for example, a flat tire while driv-
ing).
∙ The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted on all four tires. Af-
ter all four tires are inflated to the rec-
ommended pressure, the vehicle must
be driven at speeds above 16 mph
(25 km/h) to activate the TPMS and turn
off the low tire pressure warning light.
Use a tire pressure gauge to check the
tire pressure.
∙ The “Tire Pressure Low - Add Air” warn- ing appears in the vehicle information
display when the low tire pressure
warning light is illuminated and low tire
pressure is detected. The “Tire Pressure
Low - Add Air” warning turns off when
the low tire pressure warning light turns
off. ∙ The “Tire Pressure Low - Add Air” warn-
ing appears each time the ignition
switch is placed in the ON position as
long as the low tire pressure warning
light remains illuminated.
∙ The “Tire Pressure Low - Add Air” warn- ing does not appear if the low tire pres-
sure warning light illuminates to indi-
cate a TPMS malfunction.
∙ Tire pressure rises and falls depending on the heat caused by the vehicle’s op-
eration and the outside temperature.
Do not reduce the tire pressure af ter
driving because the tire pressure rises
af ter driving. Low outside temperature
can lower the temperature of the air
inside the tire which can cause a lower
tire inflation pressure. This may cause
the low tire pressure warning light to
illuminate. If the warning light illumi-
nates, check the tire pressure for all four
tires.
∙ The Tire and Loading Information label is located in the driver’s door opening. ∙ You can also check the tire pressure of
all tires (except the spare) on the vehicle
information display screen. The order of
the tire pressure figures displayed on
the screen corresponds with the actual
order of the tire position.
For additional information, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section, “Tire Pressure Moni-
toring System (TPMS)” in the “In case of
emergency” section and “Tire pressure” in
the “Do-it-yourself ” section of this manual.
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.
5-6Starting and driving

∙ If the low tire pressure warning lightilluminates 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 underinflated 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. (For additional informa-
tion, refer to “Flat tire” in the “In case of
emergency ” section for changing a
flat tire.) ∙ When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, tire pressure will not be indi-
cated, 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. It is
recommended that you visit a NISSAN
dealer for tire replacement and/or
system resetting.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ 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.
CAUTION
Do not place metalized film or any
metal parts (antenna, etc.) on the win-
dows. This may cause poor reception of
the signals from the tire pressure sen-
sors, and the TPMS will not function
properly. Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate.
Some examples are:
∙ Facilities or electric devices using simi- lar radio frequencies are near the ve-
hicle.
∙ If a transmitter set to similar frequen- cies is being used in or near the vehicle.
∙ If a computer (or similar equipment) or a DC/AC converter is being used in or
near the vehicle.
The low tire pressure warning light may
illuminate in the following cases: ∙ If the vehicle is equipped with a wheel and tire without TPMS.
∙ If the TPMS has been replaced and the ID has not been registered.
∙ If the wheel is not originally specified by NISSAN.

I-LI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the I-LI system. Failure to follow the
warnings and instructions for proper
use of the I-LI system could result in
serious injury or death.
∙ The I-LI system may activate if youchange lanes without first activating
your turn signal or, for example, if a
construction zone directs traffic to
cross an existing lane marker. If this
occurs you may need to apply correc-
tive steering to complete your lane
change.
∙ Because the I-LI may not activate un- der the road, weather, and lane
marker conditions described in this
section, it may not activate every time
your vehicle begins to leave its lane
and you will need to apply corrective
steering.
∙ When the I-LI system is operating, avoid excessive or sudden steering
maneuvers. Otherwise, you could lose
control of the vehicle. ∙ The I-LI system will not operate at
speeds below approximately 37 mph
(60 km/h) or if it cannot detect lane
markers.
∙ Do not use the I-LI system under the following conditions as it may not
function properly:
– During bad weather (rain, fog, snow, etc.).
– When driving on slippery roads, such as on ice or snow.
– When driving on winding or un- even roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshif t or temporary lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-
standard wheels). – When the vehicle is equipped with
nonoriginal brake parts or suspen-
sion parts.
– When you are towing a trailer or other vehicle.
– On roads where there are multiple parallel lane markers; lane mark-
ers that are faded or not painted
clearly; yellow painted lane mark-
ers; non-standard lane markers; or
lane markers covered with water,
dirt, snow, etc.
– On roads where discontinued lane markers are still detectable.
– On roads where there are sharp curves.
– On roads where there are sharply contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs. (The I-LI system could
detect these items as lane
markers.)
– On roads where the traveling lane merges or separates.

∙ Excessive noise will interfere with the warning chime sound, and the beep
may not be heard.
∙ For the ProPILOT Assist system to op- erate properly, the windshield in front
of the camera must be clean. Replace
worn wiper blades. The correct size
wiper blades must be used to help
make sure the windshield is kept
clean. Only use Genuine NISSAN wiper
blades, or equivalent wiper blades,
that are specifically designed for use
on your vehicle model and model
year. It is recommended that you visit
a NISSAN dealer for the correct parts
for your vehicle.Steering Assist temporary
standby
Automatic standby due to driving opera-
tion:
When the driver activates the turn signal,
the Steering Assist is temporarily placed in
a standby mode. (The Steering Assist re-
starts automatically when the operating
conditions are met again.)
Automatic standby:
In the following cases, a warning message
is displayed along with the chime, and the
Steering Assist is placed in a temporary
standby mode. (The Steering Assist re-
starts automatically when the operating
conditions are met again.)
∙ When lane markers on both sides are no longer detected
∙ When a vehicle ahead is no longer de- tected under approximately 37 mph
(60 km/h)
5-118Starting and driving

– When replacing tires, install thespecified size of tires on all four
wheels.
– 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 abov
e3-6mph(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.
