warning light INFINITI QX50 2021 Repair Manual

•Use only an original equipment type fuel-
filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap can
result in a serious malfunction and pos-
sible injury. It could also cause the
Malfunction Indicator Light (MIL) to
come on.
• Never pour fuel into the throttle body to
attempt to start your vehicle.
• Do not fill a portable fuel container in the
vehicle or trailer. Static electricity can
cause an explosion of flammable liquid,
vapor or gas in any vehicle or trailer. To
reduce the risk of serious injury or death
when filling portable fuel containers:
– Always place the container on the
ground when filling.
– Do not use electronic devices when
filling.
– Keep the pump nozzle in contact with
the container while you are filling it.
– Use only approved portable fuel con-
tainers for flammable liquid.
CAUTION
• Do not use a fuel containing more than
15% ethanol in your vehicle. For addi-
tional information, see “Fuel recommen-
dation” (P. 10-3).
• The Loose Fuel Cap warning message
will be displayed if the fuel-filler cap is
not properly tightened. It may take a few
driving trips for the message to be dis-
played. Failure to tighten the fuel-filler
cap properly after the Loose Fuel Cap
warning is displayed may cause the Mal-
function Indicator Light (MIL) to
illuminate.
• Failure to tighten the fuel-filler cap
properly may cause the
Malfunc-
tion Indicator Light (MIL) to illuminate.
If the
light illuminates because the
fuel-filler cap is loose or missing, tighten
or install the cap and continue to drive
the vehicle. The
light should turn off
after a few driving trips. If thelight
does not turn off after a few driving
trips, have the vehicle inspected. It is rec-
ommended that you visit an INFINITI re-
tailer for this service. •
For additional information, see “Mal-
function Indicator Light (MIL)”
(P. 2-15).
• If fuel is spilled on the vehicle body, flush
it away with water to avoid paint
damage.

WARNING
• The distance guide lines and the vehicle
width 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
of the vehicle.

Additional information:
• When replacing a wheel without the TPMSsuch as the spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
• The TPMS will activate only when the ve- hicle 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).
• The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted. After the tire is in-
flated to the recommended pressure, the
vehicle must be driven at speeds above 16
mph (25 km/h) to activate the TPMS and
turn off the low tire pressure warning light.
Use a tire pressure gauge to check the tire
pressure.
• The “Tire Pressure Low — Add Air” warning appears in the vehicle information display
when the low tire pressure warning light is
illuminated and low tire pressure is de-
tected. The “Tire Pressure Low - Add Air”
warning turns off when the low tire pres-
sure warning light turns off.
• The “Tire Pressure Low — Add Air” warning appears each time the ignition switch is in
the ON position as long as the low tire
pressure warning light remains illuminated. • The “Tire Pressure Low — Add Air” warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
• Tire pressure rises and falls depending on the heat caused by the vehicle’s operation
and the outside temperature. Do not re-
duce the tire pressure after driving because
the tire pressure rises after driving. Low
outside temperature can lower the tem-
perature of the air inside the tire which can
cause a lower tire inflation pressure. This
may cause the low tire pressure warning
light to illuminate. If the warning light illu-
minates, check the tire pressure for all four
tires.
• The Tire and Loading Information label is located in the driver's door opening.
• You can also check the pressure of all tires (except the spare tire) on the vehicle infor-
mation display screen. The order of the tire
pressure figures displayed on the screen
corresponds with the actual order of the
tire position.
For additional information, see “Low tire
pressure warning light” (P. 2-13) and “Tire
Pressure Low — Add Air” (P. 2-24).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 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 you have a flat tire, replace it with
a replacement tire as soon as possible.
(For additional information, see “Flat
tire” (P. 6-3) for changing a flat tire.)
5-6Starting and driving

•When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is re-
placed, tire pressure will not be indi-
cated, 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 recom-
mended that you visit an INFINITI re-
tailer for this service.
• 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.
CAUTION
• The TPMS may not function properly
when the wheels are equipped with tire
chains or the wheels are buried in snow.
• Do not place metalized film or any metal
parts (antenna, etc.) on the windows.
This may cause poor reception of the sig-
nals from the tire pressure sensors, and
the TPMS will not function properly. Some devices and transmitters may tempo-
rarily interfere with the operation of the
TPMS and cause the low tire pressure warn-
ing light to illuminate.
Some examples are:
• Facilities or electric devices using similar
radio frequencies are near the vehicle.
• If a transmitter set to similar frequencies is being used in or near the vehicle.
• If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may illu-
minate in the following cases:
• If the vehicle is equipped with a wheel and tire without TPMS.
• If the TPMS has been replaced and the ID has not been registered.
• If the wheel is not originally specified by INFINITI.
