2021 INFINITI QX50 Old port

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 ve-
hicle as soon as you can:
• After a rainfall to prevent possible damagefrom acid rain.
• After 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 vehicle
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 surface
when putting on or removing the body cover.
WASHING
Wash dirt off with a wet sponge and plenty
of water. Clean the vehicle thoroughly using 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 directly
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 ve-
hicle. Use of high-pressure washers over
1,200 psi (8,274 kPa) can result in dam-
age to or removal of paint or graphics.
Avoid using a high-pressure washer
closer than 12 inches (30 cm) to the ve-
hicle. 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 clean-
ing. The acid may react with some plastic
vehicle components, causing them to
crack. This could affect their appear-
ance, and also could cause them not to
function 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 deter-
gents, gasoline or solvents. •
Do not wash the vehicle in direct sunlight
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 substances 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. Therefore, 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 ve-
hicle to avoid water spots.
WAXING
Regular waxing protects the paint surface
and helps retain new vehicle appearance.
Polishing is recommended to remove built-up
wax residue and to avoid a weathered ap-
pearance before re-applying wax.
An INFINITI retailer can assist you in choos-
ing the proper product.
CLEANING EXTERIOR
7-2Appearance and care

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 pace-
maker should contact the electric medical
equipment manufacturer for the possible
influences before use.
This vehicle is equipped with the Tire Pres-
sure 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” warn-
ing appears in the vehicle information display,
one or more of your tires is significantly
under-inflated. If equipped, the system also
displays pressure of all tires (except the spare
tire) on the display 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. 2-13), “Tire Pres-
sure 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 specifica-
tions 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 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 moderate speeds.
TPMS with Tire Inflation Indicator provides vi-
sual 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).
Incorrect tire pressure, including under infla-
tion, may adversely affect tire life and ve-
hicle handling.
WARNING
• Improperly inflated tires can fail sud-
denly and cause an accident.
• The Gross Vehicle Weight Rating
(GVWR) is located on the F.M.V.S.S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on the
Tire and Loading Information label. Do
not load your vehicle beyond this capac-
ity. Overloading your vehicle may result
in reduced tire life, unsafe operating con-
ditions due to premature tire failure, or
unfavorable handling characteristics
and could also lead to a serious accident.
Loading beyond the specified capacity
may also result in failure of other vehicle
components.
• Before taking a long trip, or whenever
you heavily load your vehicle, use a tire
pressure gauge to ensure that the tire
pressures are at the specified level.
• 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.
WHEELS AND TIRES
Do-it-yourself8-27

•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, see "Checking tire
pressure" (P. 8-28).
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, reposition 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 release pres-
sure. Recheck the pressure and add
or release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, 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.

Other Tire-related Terminology
In addition to the many terms that are
defined throughout this section, In-
tended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears manu-
facturer, brand, and/or model name
molding that is higher or deeper than
the same molding on the other side-
wall of the tire, or (2) the outward
facing sidewall of an asymmetrical tire that has a particular side that must
always face outward when mounted
on a vehicle.
TYPES OF TIRES
WARNING
• When changing or replacing tires, be sure
all four tires are of the same type (i.e.,
Summer, All Season or Snow) and con-
struction. An INFINITI retailer may be
able to help you with information about
tire type, size, speed rating and
availability.
• Replacement tires may have a lower
speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the low tire pressure
warning system. •
Always use tires of the same type, size,
brand, construction and tread pattern on
all four wheels. Failure to do so may re-
sult in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunction re-
sulting in personal injury or death, exces-
sive tire wear and may damage the
transmission, transfer case and differen-
tial gears.
• 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.
All-Wheel Drive (AWD) models
CAUTION
• ONLY use spare tires specified for the
AWD 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
that you visit an INFINITI retailer for this
service.
Do-it-yourself8-33

The wheel nuts must be kept tightened to
specifications at all times. It is recommended
that wheel nuts be tightened to specification
at each tire rotation interval.
WARNING
• After rotating the tires, check and adjust
the tire pressure.
• Do not include the spare tire in the tire
rotation.
• 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.
Tire wear and damage
1. Wear indicator
2. Location mark
WARNING
• Tires should be periodically in-
spected for wear, cracking, bulg-
ing or objects caught in the tread.
If excessive wear, cracks, bulging
or deep cuts are found, the tire(s)
should be replaced. •
The original tires have built-in
tread wear indicators. When the
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 personal in-
jury. If it is necessary to repair the
spare tire, it is recommended that
you visit an INFINITI retailer for
this service.
• For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or

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.

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)
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 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
