2023 INFINITI QX80 TPMS

tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, it is re-
commended you visit an
INFINITI retailer for this ser-
vice.
. For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. (See “Speci-
fications” (P.10-8) for recommended types
and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted or radial), or
tread patterns can adversely affect
the ride, braking, handling, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects may
lead to accidents and could result in
serious personal injury.
. For Two-Wheel Drive (2WD) models,
if your vehicle was originally
equipped with 4 tires that were the
same size and you are only replacing
2 of the 4 tires, install the new tires
on the rear axle. Placing new tires on
the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and
personal injury. .
If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
9) for wheel off-set dimensions.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 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 you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally 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

recommended you visit an INFINITI
retailer 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
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of pres-
sure.
. Do not install a damaged or deformed
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 tire is not recom-
mended.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety
Information” (Canada) in the War-
ranty Information Booklet.Four-Wheel Drive (4WD) models
CAUTION
.Always use tires of the same type,
size, brand, construction (bias, bias-
belted or radial), and tread pattern
on all four wheels. Failure to do so
may result in a circumference differ-
ence between tires on the front and
rear axles which will cause excessive
tire wear and may damage the trans-
mission, transfer case and differential
gears.
. ONLY use spare tires specified for
the 4WD model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
you visit an INFINITI retailer for this service.
Wheel balance
Unbalanced wheels may affect vehicle hand-
ling 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
balancing the wheels on the vehicle could
lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
Spare tire
Since the spare tire is not equipped with the
TPMS, when a spare tire is mounted (TEM-
PORARY USE ONLY), the TPMS will not
function.
Spare tire (FULL-SIZE TEMPORARY USE
ONLY spare tire):
Observe the following precautions if the full-
size temporary use only spare tire must be
used, otherwise your vehicle could be da-
maged or involved in an accident.
WARNING
.
The full-size temporary use only
spare tire should be used for emer-
gency use. It should be replaced with

the standard tire at the first oppor-
tunity to avoid possible tire or differ-
ential damage
. Drive carefully while the spare tire is
installed. Avoid sharp turns and
abrupt braking while driving. The
vehicle driving performance may be
affected when driving on wet or
snow covered roads.
. When the spare tire is installed, the
following systems may not work
correctly.
— Tire Pressure Monitoring System (TPMS)
— Vehicle Dynamic Control (VDC) System
. Periodically check spare tire inflation
pressure. Always keep the spare tire
inflated to the pressure specification
shown on the Tire and Loading
Information label. For Tire and Load-
ing Information label location, see
“Tire and Loading Information label”
in the index of this manual.
. With the spare tire installed do not
drive your vehicle at speeds faster
than 70 MPH (112 km/h).
. When driving on roads covered with
snow or ice, the spare tire should be
used on the front wheels and original tire used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire
at the same time.
CAUTION
Do not use tire chains on the spare tire.
Tire chains will not fit properly and may
cause damage to the vehicle.

When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
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
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
often and always prior to long distance trips.
If necessary, adjust the pressure in all tires,
including the spare, to the pressure speci-
fied. Check carefully for damage, cuts or
excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and
cap 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
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 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 re-
paired by an INFINITI retailer, or an INFINITI
Certified Collision Center. To locate a colli-
sion center in your area, refer to http://
collision.infinitiusa.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 periodic 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.
Automatic transmission P (Park) mechan-
ism: On a fairly steep hill, check that your vehicle is held securely with the shift lever in
the P (Park) position without applying any
brakes.
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 immediately.
It is recommended 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.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, it is recommended you
visit an INFINITI retailer for this service.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjuster and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position. Check
that the head restraints/headrests move up
and down smoothly and that the locks (if so
