TPMS INFINITI QX55 2023 User Guide

Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and press thepark button to engage the P (Park)
position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation:
1. Add air to the tire.
2. After a few seconds, the hazard indicators will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard indi-
cators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more than ap-proximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the
tire briefly to release pressure. When the
pressure reaches the designated pres-
sure, the horn beeps once. • If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates
that the TPMS with Tire Inflation Indi-
cator is not operating.
• The TPMS will not activate the TPMS with Tire Inflation Indicator under the
following conditions:– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation de- vice 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 sensor is low.
• If the TPMS with Tire Inflation Indicator does not operate due to TPMS interfer-
ence, move the vehicle about 3 ft (1 m)
backward or forward and try again.
If the TPMS with Tire Inflation Indicator is
not working, use a tire pressure gauge.ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than pas-
senger cars to make them capable of per-
forming in a variety of on-pavement and off-
road applications. This gives them a higher
center of gravity than ordinary vehicles. An
advantage of higher ground clearance is a
better view of the road, allowing you to an-
ticipate problems. However, they are not de-
signed for cornering at the same speeds as
conventional 2-Wheel Drive vehicles any
more than low-slung sports cars are de-
signed to perform satisfactorily under off-
road conditions. If at all possible, avoid sharp
turns at high speeds. As with other vehicles of
this type, failure to operate this vehicle cor-
rectly may result in loss of control or vehicle
rollover.
In a rollover crash, an unbelted person is sig-
nificantly more likely to die than a person
wearing a seat belt.
For additional information, see “Driving
safety precautions” (P. 5-10).
5-8Starting and driving

•When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
• Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause
loss of control.
• If at all possible, avoid sharp turning ma-
neuvers, particularly at high speeds.
Your INFINITI vehicle has a higher center
of gravity than a passenger car. The ve-
hicle is not designed for cornering at the
same speeds as passenger cars. Failure
to operate this vehicle correctly could re-
sult 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 slippery roads
and drive carefully.
• Be sure to check the brakes immediately
after driving in mud or water. For addi-
tional information, see “Brake precau-
tions” (P. 5-139).
• 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 maintenance may be
required. For additional information, see
“Additional maintenance items for se-
vere operating conditions” (P. 9-7).
INTELLIGENT ALL-WHEEL
DRIVE (AWD) DRIVING SAFETY
PRECAUTIONS (if so equipped)
WARNING
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
• 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 slippery roads
and drive carefully.
• This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in. •
For AWD equipped vehicles, do not at-
tempt to raise two wheels off the ground
and shift the transmission to any D
(Drive) or R (Reverse) position with the
engine running. Doing so may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
• Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious vehicle dam-
age or personal injury.
• When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.

SYSTEM (TPMS)
This vehicle is equipped with Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires. When the low tire pres-
sure warning light is lit, and the “Tire Pressure
Low - Add Air” or “Flat Tire-Visit dealer” (if so
equipped) warning appears in the vehicle in-
formation display, one or more of your tires is
significantly under-inflated. The system also
displays pressure of all tires (except the spare
tire) on the vehicle information display screen
by sending a signal from a sensor that is
installed 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 acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional in-
formation, see “Warning lights, indicator
lights and audible reminders” (P. 2-9) and
“Tire Pressure Monitoring System (TPMS)”
(P. 8-27).
WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use. •
If the low tire pressure warning light illu-
minates while driving, avoid sudden
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 injury.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
OFF. If the light still illuminates while
driving after 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 replacement tire as soon
as possible. If no tires are flat and all tires
are properly inflated, have the vehicle
checked. It is recommended that you
visit an INFINITI retailer for this service.
EMERGENCY ENGINE SHUT OFF FLAT TIRE
In case of emergency6-3

•When using a wheel without TPMS such
as the spare tire, the TPMS will not func-
tion and the low tire pressure warning
light will flash for approximately 1 min-
ute. The light will remain on after 1 min-
ute. Have your tires replaced and/or
TPMS system reset as soon as possible.
It is recommended that you visit an
INFINITI retailer for these services.
• Replacing tires with those not originally
specified by INFINITI 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 pressure sensors.
RUN-FLAT TIRES
This vehicle is equipped with run-flat tires.
Run-flat tires can be used temporarily if they
are punctured. When the “Flat Tire — Visit
dealer” warning appears in the vehicle infor-
mation display, one or more of your tires is
punctured. For additional information, see
“Run-flat tires” (P. 8-36).
For additional information, refer to the tire
safety information in the Warranty Informa-
tion Booklet.
WARNING
• Although you can continue driving with a
punctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and per-
sonal injury. Also, driving a long distance
at high speeds may damage the tires.
• Do not drive at speeds above 50 mph (80
km/h) and do not drive more than ap-
proximately 93 miles (150 km) with a
punctured run-flat tire. The actual dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature, ve-
hicle load, road conditions and other
factors.
• Drive safely at reduced speeds. Avoid
hard cornering or braking, which may
cause you to lose control of the vehicle.
• If you detect any unusual sounds or vi-
brations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously dam-
aged and need to be replaced.CAUTION
• Never install tire chains on a punctured
run-flat tire, as this could damage your
vehicle.
• Avoid diving over any projection or pot-
hole, as the clearance between the ve-
hicle and the ground is smaller than
normal.
• Do not enter an automated car wash
with a punctured run-flat tire.
• Have the punctured tire inspected by an
INFINITI retailer or other authorized re-
pair shop. Replace the tire as soon as
possible if the tire is seriously damaged.

If you have a flat tire, see “Flat tire” (P. 6-3).
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
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.
This vehicle is equipped with the Tire
Pressure 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 dis-
play, one or more of your tires is sig-
nificantly under-inflated. If equipped,
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 pres-
sure (for example a flat tire while
driving).
For additional information, see “Low
tire pressure warning light” (P. 2-13),
“Tire Pressure Monitoring System
(TPMS)” (P. 5-5) and “Flat tire” (P. 6-3).
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on
the F.M.V.S.S./C.M.V.S.S. certifica-
tion label or the Tire and Loading In-
formation label under the “Cold Tire
Pressure” heading. The Tire and Load-
ing 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 objects
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 after the vehicle has
been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at mod-
erate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
see “TPMS with tire inflation indicator”
(P. 5-7).
WHEELS AND TIRES
Do-it-yourself8-27

•If the wheels are changed for any reason,
always replace with wheels which have
the same off-set dimension. Wheels of a
different off-set could cause premature
tire wear, degrade vehicle handling char-
acteristics, affect the VDC system
and/or interference with the brake
discs. Such interference can lead to de-
creased braking efficiency and/or early
brake pad wear. For additional informa-
tion on wheel off-set dimensions, see
“Wheels and tires” (P. 10-9).
• 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 approxi-
mately 1 minute. The light will remain on
after 1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit an INFINITI retailer for this service.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
• 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 recom-
mended that you visit an INFINITI re-
tailer for ID registration.
• Do not use a valve stem cap that is not
specified by INFINITI. The valve stem cap
may become stuck.
• Be sure that the valve stem caps are cor-
rectly fitted. Otherwise the valve may be
clogged up with dirt and cause a mal-
function or loss of pressure.
• Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without
warning.
• The use of retread tires is not
recommended.
• 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.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling 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 performed
with the wheels off the vehicle. Spin balanc-
ing the wheels on the vehicle could lead to
mechanical damage.
•
For additional information regarding tires,
refer to “Important Tire Safety Informa-
tion” (US) or “Tire Safety Information”
(Canada) in the Warranty Information
Booklet.
Care of wheels
• Wash the wheels when washing the vehicle 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 wash- ing the wheels.
• Inspect wheel rims regularly for dents or corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
• INFINITI recommends waxing the road wheels to protect against road salt in areas
where it is used during winter.
8-40Do-it-yourself

Doors and engine hood:Check that the doors
and engine hood operate properly. Also en-
sure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary
latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication
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 installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are miss-
ing, 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, in-
cluding 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 replaced 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 un-
even or abnormal tire wear, there may be a
need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
For additional information regarding tires, re-
fer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility. It is recommended that you have
a damaged windshield repaired by an INFINITI
retailer, or an INFINITI Certified Collision Cen- ter. To locate a collision center in your area,
refer to http://collision.infinitiusa.com.
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 op-
eration. 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 immediately.
It is recommended that you visit an INFINITI
retailer for this service. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Continuously Variable Transmission (CVT) P
(Park) position mechanism: On a fairly steep
hill check that the vehicle is held securely with
the shift position in the P (Park) position
without applying any brakes.
