warning INFINITI QX50 2020 Owners Manual

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.

CAUTION
∙ Never install tire chains on a puncturedrun-flat tire, as this could damage your
vehicle.
∙ Avoid diving over any projection or pot- hole, as the clearance between the ve-
hicle and the ground is smaller than
normal.
∙ Do not enter an automated car wash with a punctured run-flat tire.
∙ Have the punctured tire inspected by an INFINITI retailer or other authorized re-
pair shop. Replace the tire as soon as pos-
sible if the tire is seriously damaged. To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
∙ If done incorrectly, jump starting can lead
to a battery explosion, resulting in severe
injury or death. It could also damage your
vehicle.
∙ Explosive hydrogen gas is always present in the vicinity of the battery. Keep all
sparks and flames away from the
battery.
∙ Do not allow battery fluid to come into contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a corro-
sive sulfuric acid solution which can cause
severe burns. If the fluid should come into
contact with anything, immediately flush
the contacted area with water.
∙ Keep battery out of the reach of children.
∙ The booster battery must be rated at 12 volts. Use of an improperly rated bat-
tery can damage your vehicle. ∙ Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
∙ Do not attempt to jump start a frozen battery. It could explode and cause seri-
ous injury.
∙ The automatic engine cooling fan (if so equipped) may come on at any time with-
out warning, even if the ignition switch is
in the OFF position and the engine is not
running. To avoid injury, keep hands and
other objects away from it.

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.

FLOOR MATS (if so equipped)
WARNING
To avoid potential pedal interference that
may result in a collision, injury or death:
∙ NEVER place a floor mat on top of an-other floor mat in the driver front posi-
tion or install them upside down or
backwards.
∙ Use only Genuine INFINITI floor mats or equivalent floor mats, specifically de-
signed for use in your vehicle model and
model year. ∙ Properly position the mats in the floor-
well using the floor mat positioning hook.
For additional information, refer to
"Floor mat installation" in this section.
∙ Make sure the floor mat does not inter- fere with pedal operation.
∙ Periodically check the floor mats to make sure they are properly installed.
∙ After cleaning the vehicle interior, check the floor mats to make sure they are
properly installed.
The use of Genuine INFINITI floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular cleaning
and replaced if they become excessively
worn.Floor mat installation
Your vehicle is equipped with floor mat re-
tainer clips. The number and shape of the
floor mat retainer clips for each seating posi-
tion varies depending on the vehicle. When installing Genuine INFINITI floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, the shift lever in P (Park) position and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the retainer clips.
2. Secure the grommet holes into the clips and ensure that the floor mat is properly
positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shift
lever in the P (Park) position and with the
parking brake applied, fully apply and
release all pedals. The floor mat must not
interfere with pedal operation or prevent
the pedal from returning to its normal
position.
It is recommended that you visit an INFINITI
retailer for details about installing the floor
mats in your vehicle.

floor mat retainer clips.
SEAT BELTS
The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solu-
tion. Allow the belts to dry completely in the
shade before using them. For additional in-
formation, refer to “Seat belt maintenance” in
the “Safety—Seats, seat belts and supple-
mental restraint system” section of this
manual.
WARNING
Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye or chemi-
cal solvents to clean the seat belts, since
these materials may severely weaken the
seat belt webbing.
CLEANING THE SEAT TRACKS
CAUTION
Periodically clean the seat tracks to pre-
vent reduction of ability to move the seats.
Clean periodically with a high-powered
vacuum cleaner. Dirt and debris may reduce
the ability to adjust the seat. A wet cleansing
agent may be used if necessary.
MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by: ∙ The accumulation of moisture-retaining dirt and debris in body panel sections,
cavities, and other areas.
∙ Damage to paint and other protective coatings caused by gravel and stone
chips or minor traffic collisions.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on the
vehicle body underside can accelerate corro-
sion. Wet floor coverings will not dry com-
pletely inside the vehicle and should be re-
moved for drying to avoid floor panel
corrosion.
