WARNING
■Caution regarding interfer-

●People with implantable car-
diac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defib rillators should
keep away from the smart key
system antennas. ( P.120)
The radio waves may affect the
operation of such devices. If
necessary, the entry function
can be disabled. Ask your Toy-
ota dealer for details, such as
the frequency of radio waves
and timing of the emitted radio
waves. Then, consult your doc-
tor to see if you should disable
the entry function.
●Users of any electrical medical
device other than implantable
cardiac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defibrillators should
consult the manufacturer of the
device for information about its
operation under the influence of
radio waves.
Radio waves could have unex-
pected effects on the operation
of such medical devices.
Ask your Toyota dealer for details
on disabling the entry function.

1884-5. Using the driving support systems
■Situations in which the sensors
may not operate properly
●When the height or inclination of
the vehicle has been changed due
to modifications
●When the windshield is dirty,
fogged up, cracked or damaged
●When the ambient temperature is
high or low
●When mud, water, snow, dead
insects, foreign matter, etc., is
attached to the front of the sensor
●When in inclement weather such
as heavy rain, fog, snow, or a
sandstorm
●When water, snow, dust, etc. is
thrown up in front of the vehicle, or
when driving through mist or
smoke
●When the headlig hts are not illu-
minated while driving in the dark,
such as at night o r when in a tun-
nel
●When the lens of a headlight is
dirty and illumination is weak
●When the headlights are mis-
aligned
●When a headlight is malfunction-
ing
●When the headlights of another
vehicle, sunlight, or reflected light
shines directly into the front cam-
era
●When the brightness of the sur-
rounding area changes suddenly
●When driving near a TV tower,
broadcasting station, electric
power plant, radar equipped vehi-
cles, etc., or other location where
strong radio waves or electrical
noise may be present
●When a wiper blade is blocking
the front camera
●When in a location or near objects
which strongly reflect radio waves,
such as the following:
• Tunnels
• Truss bridges
• Gravel roads
• Rutted, snow-covered roads
• Walls
• Large trucks
• Manhole covers
• Guardrail
• Metal plates
●When near a step or protrusion
●When a detectable vehicle is nar-
row, such as a small mobility vehi-
cle
●When a detectable vehicle has a
small front or rear end, such as an
unloaded truck
●When a detectable vehicle has a
low front or rear end, such as a
low bed trailer
●When a detectable vehicle has
extremely high ground clearance
WARNING
■Front camera installation area
on the windshield
If the system determines that the
windshield may be fogged up, it
will automatically operate the
heater to defog the part of the
windshield around the front cam-
era. When cleaning, etc., be care-
ful not to touch the area around
the front camera until the wind-
shield has cooled sufficiently, as
touching it may cause burns.

■The wireless charger can be
operated when
The engine switch is in ACC or ON.
■Portable devices that can be
charged
●Portable devices compatible with
the Qi wireless charging standard
can be charged by the wireless
charger. However, compatibility
with all devices which meet the Qi
wireless charging standard is not
guaranteed.
●The wireless charger is designed
to supply low power electricity (5
W or less) to a cellular phone,
smartphone, or other portable
device.
■If a cover or accessory is
attached to the portable device
Do not charge a portable device if a
cover or accessory which is not Qi
compatible is attached. Depending
on the type of cover (including for certain genuine manufacture parts)
and/or accessory a
ttached, it may
not be possible to charge the porta-
ble device. If the portable device is
placed on the charging area and
does not charge, remove the cover
and/or accessories.
■If interference is heard in AM
radio broadcasts while
charging
Turn off the wireless charger and
check if the noise is reduced. If
noise is reduced, press and hold the
power supply switch of the wireless
charger for 2 se conds. The fre-
quency of the wireless charger is
changed and noise may be
reduced. When the frequency is
changed, the operation indicator
light will blink (orange) 2 times.

■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks. Make sure to
check tire inflation pressure as part
of your routine of daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the engine switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after inflation pressure
has been adjusted.
●Tire inflation pressure changes
with temperature.
The displayed values may also be
different from th e values mea-
sured using a tire pressure gauge.
■Situations in which the tire
pressure warning system may
not operate properly
●In the following cases, the tire
pressure warning system may not
operate properly.
• If non-genuine Toyota wheels are
used.
• A tire has been replaced with a tire that is not an OE (Original
Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on
the vehicle, particularly around the wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the speci-
fied level.
• If tires not equipped with tire pres- sure warning valves and transmit-
ters are used.
• If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure
warning computer.
●Performance may be affected in
the following situations.
• Near a TV tower, electric power
plant, gas station, radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise.
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication
device.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system w ill change in
accordance with driving conditions.
For this reason, the system may
give a warning even if the tire pres-
sure does not reach a low enough
level, or if the p ressure is higher
than the pressure that was adjusted
to when the system w as initialized.
