2023 NISSAN ALTIMA sensor

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pres-
sure Monitoring system (TPMS). It monitors
tire pressure of all tires except the spare.
When the low tire pressure warning light is
lit, and the “Tire Pressure Low - Add Air”
warning appears in the vehicle information
display, one or more of your tires is signifi-
cantly under-inflated. If equipped, the sys-
tem also displays pressure of all tires (ex-
cept the spare tire) on the display screen by
sending a signal from a sensor that is in-
stalled in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will
activate and warn you of it by the low tire
pressure warning light. This system will ac-
tivate only when the vehicle is driven at
speeds above 16 mph (25 km/h). For addi-
tional information, see “Warning lights, indi-
cator lights and audible reminders” (P. 2-9)
and “Tire Pressure Monitoring System
(TPMS)” (P. 5-5).
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.
• 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.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving af-
ter adjusting the tire pressure, a tire
may be flat or the TPMS may be mal-
functioning. If you have a flat tire, re-
place it with a spare tire as soon as possible. If no tire is flat and all tires
are properly inflated, have the ve-
hicle checked. It is recommended
that you visit a NISSAN dealer for this
service.
• When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately one minute. Have
your tires replaced and/or TPMS sys-
tem reset as soon as possible. It is
recommended that you visit a
NISSAN dealer for these services.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• The Genuine NISSAN Emergency Tire
Repair Sealant or equivalent can be
used for temporarily repairing a tire.
Do not inject any other tire liquid or
aerosol tire sealant into the tires, as
this may cause a malfunction of tire
pressure sensors.

If the tire pressure does not increase to26
psi (180 kPa) within 10 minutes, the tire
may be seriously damaged and the tire
cannot be repaired with this tire repair
kit. It is recommended that you visit a
NISSAN dealer.
7. When the tire pressure is at the specified amount, turn the air compressor off. If
the tire cannot be inflated to the speci-
fied amount, the air compressor can be
turned off at the minimum of 26 psi (180
kPa). Remove the power plug from the
power outlet and quickly remove the
hose from the tire valve. Attach the pro-
tective cap and valve cap. Properly stow
the emergency tire puncture repair kit in

the compressor. Failure to do so can
cause the sealant to spray into the air
and get into your eyes or on the skin. 8. Immediately drive the vehicle for 10 min-
utes or 2 miles (3 km) at a speed below
50 mph (80 km/h).
9. Af ter driving, make sure that the air compressor switch is in the OFF posi-
tion, then screw the hose securely onto
the tire valve. Check the tire pressure
with the pressure gauge. Temporary re-
pair is completed if the tire pressure
does not drop.
Make sure the pressure is adjusted to
the pressure that is specified on the Tire
and Loading Information label before
driving.
10. If the tire pressure drops, repeat the steps from 5 to 9. If the pressure drops
again or under 19 psi (130 kPa), the tire
cannot be repaired with this tire re-
pair kit. If the tire cannot be repaired,
the driver should not drive on it any
further. The car should be towed to the
nearest dealership.
The sealant bottle and hose cannot be
reused to repair another punctured tire.

•If you used the Genuine NISSAN
Emergency Tire Sealant to repair a
minor tire puncture, it is recom-
mended that you visit a NISSAN
dealer to replace the TPMS sensor in
addition to repairing or replacing the
tire.
• NISSAN recommends using only
Genuine NISSAN Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure. To start your engine with a booster battery,
the instructions and precautions below
must be followed.
WARNING
• If done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
• Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away
from the battery.
• Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulfuric acid solution which
can cause severe burns. If the fluid
should come into contact with any-
thing, immediately flush the con-
tacted area with water.
• Keep battery out of the reach of
children.
• The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle. •
Whenever working on or near a bat-
tery, always wear suitable eye pro-
tectors (for example, goggles or in-
dustrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
battery when jump starting.
• Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
• Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
JUMP STARTING
In case of emergency6-17

In order to maintain the appearance of
your vehicle, it is important to take proper
care of it.
To protect the paint surfaces, wash your
vehicle as soon as you can:
• Af ter a rainfall to prevent possible dam-age from acid rain.
• Af ter driving on coastal roads.
• When contaminants such as soot, bird droppings, tree sap, metal particles or
bugs get on the paint surface.
• When dust or mud builds up on the surface.
Whenever possible, store or park your ve-
hicle inside a garage or in a covered area.
When it is necessary to park outside, park in
a shady area or protect the vehicle with a
body cover.
Be careful not to scratch the paint sur-
face when putting on or removing the
body cover.
WASHING
Wash dirt off with a wet sponge and plenty
of water. Clean the vehicle thoroughly us-
ing a mild soap, a special vehicle soap or
general purpose dishwashing liquid mixed
with clean, lukewarm (never hot) water.
CAUTION
• Do not concentrate water spray di-
rectly on the sonar sensors (if so
equipped) on the bumper as this will
result in damage to the sensors. Do
not use pressure washers capable of
spraying water over 1,200 psi (8,274
kPa) to wash your vehicle. Use of
high-pressure washers over 1,200 psi
(8,274 kPa) can result in damage to or
removal of paint or graphics. Avoid
using a high-pressure washer closer
than 12 inches (30 cm) to the vehicle.
Always use a wide-angle nozzle only,
keep the nozzle moving and do not
concentrate the water spray on any
one area.
• Do not use car washes that use acid
in the detergent. Some car washes,
especially brushless ones, use some
acid for cleaning. The acid may react
with some plastic vehicle compo-
nents, causing them to crack. This
could affect their appearance, and
also could cause them not to func-
tion properly. Always check with your
car wash to confirm that acid is not
used. •
Do not wash the vehicle with strong
household soap, strong chemical de-
tergents, gasoline or solvents.
• Do not wash the vehicle in direct sun-
light or while the vehicle body is hot,
as the surface may become
water-spotted.
• Avoid using tight-napped or rough
cloths, such as washing mitts. Care
must be taken when removing
caked-on dirt or other foreign sub-
stances so the paint surface is not
scratched or damaged.
Rinse the vehicle thoroughly with plenty of
clean water.
Inside edges, seams and folds on the
doors, hatches and hood are particularly
vulnerable to the effects of road salt. There-
fore, these areas must be cleaned regularly.
Take care that the drain holes in the lower
edge of the door are open. Spray water
under the body and in the wheel wells to
loosen the dirt and wash away road salt.
A damp chamois can be used to dry the
vehicle to avoid water spots.
CLEANING EXTERIOR
7-2Appearance and care

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.
CAUTION
• Never use benzine, thinner or any
similar material.
• Small dirt particles can be abrasive
and damaging to leather surfaces
and should be removed promptly. Do
not use saddle soap, car waxes, pol-
ishes, oils, cleaning fluids, solvents,
detergents or ammonia-based
cleaners as they may damage the
leather's natural finish.
• Never use fabric protectors unless
recommended by the manufacturer.
• Do not use glass or plastic cleaner on
meter or gauge lens covers. It may
damage the lens cover.
• Never use chloride solutions for
cleaning aluminum decoratives (if so
equipped), damage may occur.AIR FRESHENERS
Most air fresheners use a solvent that
could affect the vehicle interior. If you use
an air freshener, take the following
precautions:
• Hanging-type air fresheners can cause permanent discoloration when they con-
tact vehicle interior surfaces. Place the air
freshener in a location that allows it to
hang free and not contact an interior
surface.
• Liquid-type air fresheners typically clip on the vents. These products can cause im-
mediate damage and discoloration
when spilled on interior surfaces.
Carefully read and follow the manufactur-
er's instructions before using the air
fresheners.
