2022 INFINITI QX50 sensor

Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. For addi-
tional information, see “Wheels and tires”
(P. 10-9).
WARNING
• The use of tires other than those recom-
mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can
adversely affect the ride, braking, han-
dling, VDC system, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, headlight
aim and bumper height. Some of these
effects may lead to accidents and could
result in serious personal injury.
• For 2WD models, if your vehicle was
originally equipped with four tires that
were the same size and you are only re-
placing two of the four 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 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.
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 in a fully open position. 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 TPMS tire pressure sensor as-
sembly 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 regu-
lar 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 Center. To locate a collision 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 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.
