sensor NISSAN MAXIMA 2023 Manual PDF

The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the sonar sensors.
Check for and remove objects obstructing
the area around the sonar sensors.
Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the sonar sensors is damaged due to a
collision.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry function on the Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
see “Engine cooling system” (P. 8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For ad-
ditional information, see “Battery” (P. 8-14).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, see
“Changing engine coolant” (P. 8-5).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors 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 infor-
mation display, one or more of your tires is
significantly under-inflated. 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 activate only when the vehicle is driven
at speeds above 16 mph (25 km/h). For ad-
ditional information, see “Warning lights,
indicator lights and audible reminders”
(P. 2-8) and “Tire Pressure Monitoring Sys-
tem (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 1 minute. The light will
remain 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.
• 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.
• If the light still comes on while driving
af ter adjusting the tire pressure, a
tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a spare tire as soon as
possible. If no tire is flat and all tires
are properly inflated, it is recom-
mended that you visit a NISSAN
dealer for this service.
FLAT TIRE
In case of emergency6-3

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.
CLEANING INTERIOR
Appearance and care7-5

the system also displays pressure of all
tires (except the spare tire) on the dis-
play screen by sending a signal from a
sensor that is installed in each wheel.
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
pressure (for example a flat tire while
driving).
For additional information, see “Low
tire pressure warning light” (P. 2-12),
“Tire Pressure Monitoring System
(TPMS)” (P. 5-5) and “Flat tire” (P. 6-3).
Tire inflation pressure
Check the tire pressures (including
the spare) of ten and always prior to
long distance trips. The recom-
mended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S.
certification label or the Tire and
Loading Information label under the"Cold Tire Pressure" heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
• Most tires naturally lose air over
time.
• Tires can lose air suddenly when driven over potholes or other ob-
jects or if the vehicle strikes a curb
while parking.
The tire pressures should be
checked when the tires are cold. The
tires are considered COLD af ter the
vehicle has been parked for 3 or
more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.
The TPMS with Easy-Fill Tire Alert pro-
vides visual and audible signals out-
side the vehicle for inflating the tires
to the recommended COLD tire pres-
sure. For additional information, see
“TPMS with Easy-Fill Tire Alert” (P. 5-7).
If the tires are used at speeds above
100 mph (162 km/h) where it is legal
to do so (on a race track for ex-
ample), the cold tire inflation pres-
sure must be increased. For addi-
tional information, see “Checking tire
pressure” (P. 8-31).
Set the tire pressure to the normal
cold tire inflation pressure when the
vehicle speed or load is reduced.
Incorrect tire pressure, including
under inflation, may adversely af-
fect tire life and vehicle handling.

Do-it-yourself

•The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
• When replacing the TPMS sensor, the
ID registration may be required. It is
recommended that you visit a
NISSAN dealer for ID registration.
• Do not use a valve stem cap that is
not specified by NISSAN. The valve
stem cap may become stuck.
•
Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and cause
a malfunction or loss of pressure.
• Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
• For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Care of wheels
• Wash the wheels when washing the ve- hicle to maintain their appearance.
• Clean the inner side of the wheels when the wheel is changed or the underside of
the vehicle is washed.
• Do not use abrasive cleaners when washing the wheels.
• Inspect wheel rims regularly for dents or corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
• NISSAN recommends waxing the road wheels to protect against road salt in ar-
eas where it is used during winter.
Spare tire (TEMPORARY USE ONLY
spare tire)
When using a wheel without the TPMS such
as the spare tire, the TPMS will not function.
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used. Otherwise, your vehicle could be
damaged or involved in an accident:
WARNING
• The spare tire should be used for
emergency use only. It should be re-
placed with the standard tire at the
first opportunity to avoid possible
tire or differential damage.
• Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
• Periodically check spare tire inflation
pressure. Always keep the pressure
of the TEMPORARY USE ONLY spare
tire at 60 psi (420 kPa, 4.2 bar).
•
With the TEMPORARY USE ONLY spare
tire installed do not drive the vehicle at
speeds faster than 50 mph (80 km/h).

Outside the vehicle
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Doors and engine hood:
Check that the
doors and engine hood operate properly.
Also ensure that all latches lock securely. Lu-
bricate hinges, latches, latch pins, rollers and
links if necessary. Make sure that the sec-
ondary latch keeps the hood from opening
when the primary latch is released.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch fully open. If the hood, trunk, or rear
hatch is not held open, have the gas stays
or struts replaced.
Lights*: Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary. Tire rotation*:
Rotate tires at the specified
interval shown in the maintenance
schedule.
Tires*: Check the pressure with a gauge
of ten and always prior to long distance
trips. If necessary, adjust the pressure in all
tires, including the spare, to the pressure
specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
tire pressure sensor: It is recommended
that you replace the TPMS tire pressure
sensor assembly when the tires are re-
placed due to wear or age.
Wheel alignment and balance: If the
vehicle should pull to either side while
driving on a straight and level road, or if you
detect uneven or abnormal tire wear, there
may be a need for wheel alignment. If the
steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet. Windshield:
Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility. It is recom-
mended that you have a damaged wind-
shield repaired by a NISSAN dealer, or a
NISSAN Certified Collision Center. To locate
a collision center in your area, refer to
http://collision.nissanusa.com.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled maintenance,
cleaning the vehicle, etc.
Accelerator pedal:
Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, have your vehicle checked
