tire size INFINITI QX50 2020 Owner's Manual

Tire and Loading Information label
1Seating capacity: The maximum
number of occupants that can be
seated in the vehicle.
2Original tire size: The size of the
tires originally installed on the ve-
hicle at the factory.
3Cold tire pressure: Inflate the tires
to this pressure when the tires are
cold. 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 moderate
speeds. The recommended cold
tire inflation is set by the manu-
facturer to provide the best bal-
ance of tire wear, vehicle handling,
driveability, tire noise, etc., up to
the vehicle’s GVWR.
4Tire size - refer to “Tire labeling” in
this section.
5Spare tire size.
6Vehicle load limit: Refer to “Ve-
hicle loading information” in the
“Technical and consumer informa-
tion” section of this manual.

Checking tire pressure
WARNING
∙ Driving at high speeds, 100 mph (160 km/h) or higher sustained
where it is legal to do so, can cause
tires to have excessive heat build
up, which may result in a tire fail-
ure causing loss of control, crash,
injuries or even death. ∙ Some high-speed rated tires re-
quire inflation pressure adjust-
ment for high-speed operation.
When speed limits and road condi-
tions allow vehicle driving at high
speeds, make sure tires are rated
to support high speed operation,
tires are in optimal conditions and
pressure is adjusted to correct cold
inflation pressure for high speed
operation.
∙ If your vehicle is equipped with P235/55RF19 or P255/45RF20
tire sizes, tires require adjustment
to the inflation pressure when
driving the vehicle at speeds of
100 mph (160 km/h) or higher
where it is legal to do so. Set the
cold inflation pressure to 36 psi
(250 kPa).
∙ After vehicle high speed operation has ended, readjust the tire pres-
sure to the recommended cold in-
flation pressure, For additional in-
formation refer to the "Checking
tire pressure" section of this
manual. 1. Remove the valve stem cap from
the tire.
2. Press the pressure gauge squarely onto the valve stem. Do
not press too hard or force the
valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard
while checking the pressure, re-
position the gauge to eliminate
this leakage.
3. Remove the gauge.
4. Read the tire pressure on the gauge stem and compare to the
specification shown on the Tire
and Loading Information label.
5. Add air to the tire as needed. If too much air is added, press the
core of the valve stem briefly with
the tip of the gauge stem to re-
lease pressure. Recheck the pres-
sure and add or release air as
needed.
6. Install the valve stem cap.
LDI0393

7. Check the pressure of all othertires, including the spare.
8. Check the pressure when driving the vehicle at speeds of 100 mph
(160 km/h) or higher where it is
legal to do so.

Seat belt hook
When the seat belt is not in use and when
folding down the rear seats, hook the rear
seat belts on the seat belt hooks.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the lap/shoulder
belt and fasten it, an extender that is compat-
ible with the installed seat belts is available
for purchase. The extender adds approxi-
mately 8 in (200 mm) of length and may be
used for all seating positions.Seat belt extenders are available for the:
∙ Driver and front passenger seating posi- tions
∙ Rear seating positions
It is recommended that you visit an INFINITI
retailer for assistance with purchasing an ex-
tender if an extender is required.
WARNING
∙ Only INFINITI seat belt extenders, made by the same company which made the
original equipment seat belts, should be
used with INFINITI seat belts.
∙ Adults and children who can use the stan- dard seat belt should not use an extender.
Such unnecessary use could result in seri-
ous personal injury in the event of an
accident.
∙ Never use seat belt extenders to install child restraints. If the child restraint is
not secured properly, the child could be
seriously injured or killed in a collision or a
sudden stop.
SEAT BELT MAINTENANCE
∙ To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or car-
pet. Then wipe with a cloth and allow the
seat belts to dry in the shade. Do not
allow the seat belts to retract until they
are completely dry.
∙ If dirt builds up in the shoulder belt guide
of the seat belt anchors, the seat belts
may retract slowly. Wipe the shoulder
belt guide with a clean, dry cloth.
∙ Periodically check to see that the seat
belt and the metal components, such as
buckles, tongues, retractors, flexible
wires and anchors, work properly. If loose
parts, deterioration, cuts or other dam-
age on the webbing is found, the entire
seat belt assembly should be replaced.

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 light does not illuminate with the ignition switch placed in the ON position,
have the vehicle checked as soon as pos-
sible. It is recommended that you visit an
INFINITI retailer for this service. ∙ If the light illuminates 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 perma-
nently 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 per-
sonal injury or death. Check the tire pres-
sure for all four tires. Adjust the tire pres-
sure to the recommended COLD tire
pressure show on the Tire and Loading
Information label located in the driver’s
door opening to turn the low tire pressure
warning light OFF. If the light still illumi-
nates 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 replace-
ment tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service. ∙ When replacing 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 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 these services.
∙ Replacing tires with those not originally specified by INFINITI 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.

Under the following conditions, the Steering
Assist system is automatically canceled:∙ When lane markers in the traveling lane cannot be correctly detected for a period
of time due to such items as a snow rut,
reflection of light on a rainy day or several
unclear lane markers are present
If you want to use the Steering Assist system
again, cancel the ProPILOT Assist system
and set it again when lane markers are clearly
visible.

WARNING
∙ The distance guide lines and the vehiclewidth lines should be used as a reference
only when the vehicle is on a paved, level
surface. The apparent distance viewed
on the monitor may be different than the
actual distance between the vehicle and
displayed objects.
∙ Use the displayed lines and the bird’s-eye view as a reference. The lines and the
bird’s-eye view are greatly affected by
the number of occupants, cargo, fuel
level, vehicle position, road condition and
road grade.
∙ If the tires are replaced with different sized tires, the predicted course lines and
the bird’s-eye view may be displayed
incorrectly. ∙ When driving the vehicle up a hill, objects
viewed in the monitor are further than
they appear. When driving the vehicle
down a hill, objects viewed in the monitor
are closer than they appear.
∙ Objects in the rear view will appear visu- ally opposite compared to when viewed
in the monitor and outside mirrors.
∙ Use the mirrors or actually look to prop- erly judge distances to other objects.
∙ On a snow-covered or slippery road, there may be a difference between the
predicted course lines and the actual
course line.
∙ The vehicle width and predicted course lines are wider than the actual width and
course.
∙ The displayed lines will appear slightly off to the right, because the rearview
camera is not installed in the rear center
