■If the tire pressure warning system is inoperative
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition be
comes normal, the system will work properly.)
●If tires not equipped with tire pressure 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.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher.
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition be comes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
●If non-genuine Toyota wheels are used (Even if you use Toyota
wheels, the tire pressu re warning system may not work properly with
some types of tires.)
●If tire chains are used.
●If a large metallic object which can interfere with signal reception is
put in the luggage compartment.
■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1
minute when the “POWER” switch is turned to ON mode, have it
checked by your Toyota dealer.
■ Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 500) However, Toyota recommends that the
seat belt reminder buzzer be operational to alert the driver and front passen-
ger that the seat belts are not fastened.

CAUTION
■When the electric power steering warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
■ If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a
loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire infla-
tion pressure immediately.
● If the tire pressure warning light comes on even after tire inflation pressure
adjustment, it is probable that you have a flat tire. Check the tires. If the
tire is flat, temporarily repair it with liquid sealants and have the flat tire
repaired or replaced by the nearest Toyota dealer as soon as possible.
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
■
If a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.

■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle
placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pre ssure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency (for electric vehicles, traction
battery efficiency) and tire tread lif e, and may affect the vehicle's han-
dling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper ti re maintenance, an d it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low ti re pressure telltale (tire
pressure warning light).

426 5-2. Steps to take in an emergency
CAUTION
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indicate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installati on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
NOTICE
■Precaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pres-
sure warning system may not operate properly.

456 5-2. Steps to take in an emergency
Check the specified tire inflation
pressure.
Tire inflation pressure is speci-
fied on the label on the driver's
side pillar as shown. (P. 488)
Start the EV system.
To inject the sealant and inflate
the tire, turn the compressor
switch on.

5-2. Steps to take in an emergency
Inflate the tire until the specified
air pressure is reached.
The sealant will be injected
and the pressure will spike to
44 psi (300 kPa, 3.1 kgf/cm
2
or bar) to 58 psi (400 kPa, 4.1
kgf/cm2 or bar), and then
gradually decrease.
The air pressure gauge will
display the actual tire inflation
pressure about 1 minute (15
minutes at low temperature)
after the switch is turned on.
Inflate the tire until the speci-
fied air pressure.
• Turn the compressor switch off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the inflation
procedure until the specified
tire inflation pressure is
reached.
• If the tire inflation pressure is still lower than the specified
point after inflation for 10
minutes (35 minutes at low
temperature) with the switch
on, the tire is too damaged to
be repaired. Turn the com-
pressor switch off and con-
tact your Toyota dealer.

458 5-2. Steps to take in an emergency
• If the tire inflation pressureexceeds the specified air
pressure, let out some air to
adjust the tire inflation pres-
sure. ( P. 460, 488)
With the compressor switch off, disconnect the hose from the
valve on the tire and then pull out the power plug from the
power outlet socket.
Some sealant may leak when the hose is removed.
Install the valve cap onto the valve of the emergency repaired
tire.
Attach the air release cap to the
end of the hose.
If the air release cap is not
attached, the sealant may leak
and the vehicle may get dirty.
Do not insert sharp objects into
the tip of the bottle's hose.
Temporarily store the bottle in the luggage compartment while
it is connected to the compressor.
To spread the liquid sealant evenl y within the tire, immediately
drive safely for about 3 miles (5 km) below 50 mph (80 km/h).
After driving for about 3 miles (5
km), stop your vehicle in a safe
place on a hard, flat surface and
remove the air release cap from
the hose before reconnecting the
repair kit.
