2020 INFINITI QX50 tires

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For additional information, refer to
“Changing engine coolant” in the “Do-it-
yourself” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all
four wheels. It is recommended that you
visit an INFINITI retailer for the tire type,
size, speed rating and availability infor-
mation.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires. Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.
3. Tire chains may be used. For additional information, refer to “Tire chains” in the
“Do-it-yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
∙ A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.
∙ A sturdy, flat board to be placed under the jack to give it firm support.
∙ A shovel to dig the vehicle out of snow- drifts.
∙ Extra washer fluid to refill the windshield-washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
∙ Wet ice (32°F, 0°C and freezing rain),very cold snow or ice can be slick and very
hard to drive on. The vehicle will have
much less traction or “grip” under these
conditions. Try to avoid driving on wet
ice until the road is salted or sanded.
∙ Whatever the condition, drive with cau- tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even more
traction.
∙ Allow more stopping distance under these conditions. Braking should be
started sooner than on dry pavement.
∙ Allow greater following distances on slippery roads.
∙ Watch for slippery spots (glare ice). These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
∙ Do not use the cruise control on slippery roads.

To shut off the engine in an emergency situ-
ation while driving, perform the following
procedure:
– Rapidly push the push-button ignitionswitch three consecutive times in less than
1.5 seconds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
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” warning appears in the vehicle
information 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, refer to “Warning lights, indicator
lights and audible reminders” in the “Instru-
ments and controls” section and “Tire Pres-
sure Monitoring System (TPMS)” in the
“Starting and driving” sections of this manual.
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.
EMERGENCY ENGINE SHUT OFF FLAT TIRE
In case of emergency6-3

∙ 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, re-
place 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. ∙ When replacing a wheel without TPMS
such as the spare tire, the TPMS will not
function and the low tire pressure warn-
ing 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.
∙ 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, refer
to “Run-flat tires” in the “Do-it-yourself” sec-
tion of this manual.
For additional information, refer to the tire
safety information in the Warranty Informa-
tion Booklet.
WARNING
∙ Although you can continue driving with apunctured 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
approximately 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.

VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck
vehicle:
∙ Contact a professional towing service torecover the vehicle if you have any ques-
tions regarding the recovery procedure.
∙ Tow chains or cables must be attached only to main structural members of the
vehicle.
∙ Do not use the vehicle tie-downs to tow or free a stuck vehicle.
∙ Only use devices specifically designed for vehicle recovery and follow the manufac-
turer’s instructions.
∙ Always pull the recovery device straight out from the front of the vehicle. Never
pull at an angle.
∙ Route recovery devices so they do not touch any part of the vehicle except the
attachment point. If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device designed
specifically for vehicle recovery. Always fol-
low the manufacturer’s instructions for the
recovery device.Rocking a stuck vehicle
WARNING
∙ Stand clear of a stuck vehicle.
∙ Do not spin your tires at high speed. This
could cause them to explode and result in
serious injury. Parts of your vehicle could
also overheat and be damaged.
If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure: 1. Turn off the Vehicle Dynamic Control (VDC) system.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.
∙ Shift back and forth between R (Re- verse) and D (Drive). ∙ Apply the accelerator as little as pos-
sible to maintain the rocking motion.
∙ Release the accelerator pedal before shifting between R (Reverse) and D
(Drive).
∙ Do not spin the tires above 35 mph (55 km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional towing ser-
vice to remove the vehicle.

CHROME PARTS
Clean all chrome parts regularly with a non-
abrasive chrome polish to maintain the finish.
TIRE DRESSINGS
INFINITI does not recommend the use of tire
dressings. Tire manufacturers apply a coating
to the tires to help reduce discoloration of the
rubber. If a tire dressing is applied to the tires,
it may react with the coating and form a
compound. This compound may come off the
tire while driving and stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:∙ Use a water-based tire dressing. The coating on the tire dissolves more easily
than with an oil-based tire dressing.
∙ Apply a light coat of tire dressing to help prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove).
∙ Wipe off excess tire dressing using a dry towel. Make sure the tire dressing is com-
pletely removed from the tire
tread/grooves.
∙ Allow the tire dressing to dry as recom- mended by tire dressing manufacturer. This vehicle has new and unique surfaces on
the center console and door pull finishers. If
cleaning is required use mild soap and water.
However if mild soap and water won’t clean
the center console and door pull finishers, use
Genuine INFINITI Vinyl and Leather Cleaner
(or equivalent).
Occasionally remove loose dust from the in-
terior trim, plastic parts and seats using a
vacuum cleaner or soft bristled brush. Wipe
the vinyl and leather surfaces with a clean,
soft cloth dampened in mild soap solution,
then wipe clean with a dry, soft cloth.
Regular care and cleaning is required in order
to maintain the appearance of the leather.
Before using any fabric protector, read the
manufacturer’s recommendations. Some
fabric protectors contain chemicals that may
stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.
Use a slightly moist (with water) microfiber
cloth to clean the wood trim. If necessary, use
water with natural soap or wood dedicated
cleaning products, such as furniture polish.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can dam-
age the seat or occupant classification sen-
sor. This can also affect the operation of the
air bag system and result in serious per-
sonal injury.
CAUTION
∙ Never use benzine, thinner, or any similar
material on the interior surfaces or sur-
face damage may occur. Such damage is
not covered under the INFINITI
warranty.
∙ Small dirt particles can be abrasive and damaging to leather surfaces and should
be removed promptly. Do not use saddle
soap, car waxes, polishes, oils, cleaning
fluids, solvents, detergents or ammonia-
based cleaners as they may damage the
leather’s natural finish.
∙ Never use fabric protectors unless rec- ommended by the manufacturer.
∙ Do not use glass or plastic cleaner on me- ter or gauge lens covers. It may damage
the lens cover.

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
pressure (for example a flat tire while
driving).
For additional information, refer to
“Low tire pressure warning light” in the
“Instruments and controls” section,
“Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving”
section and “Flat tire” in the “In case of
emergency” section of this manual.
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 thedriver 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 ob-
jects 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,
refer to “TPMS with tire inflation indi-
cator” in the “Starting and driving” sec-
tion of this manual.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
