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
any authorized Toyota dealer or re pairer, or another duly qualified and
equipped professional.
■ Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location
or audio sound.

When trouble arises
WARNING
■ If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional. The vehicle will become extremely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ When the electric power steering system 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.
● Vehicles with a spare tire: 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 a tire is fl at, change it with the spare tire and have
the flat tire repaired by the nearest any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
● Vehicles with an emergency tire puncture repair kit: 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 a tire is flat, repair the
flat tire by using emergency tire puncture repair kit.
● 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 system may not activate immediately.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with different specifications or makers, as the tire pres-
sure warning system may not operate properly.

■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
● Make sure to check the tire inflation pressure of the compact spare tire.
(→ P. 461)
■ When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning valve
and transmitter, low inflation pressure of the spare tire will not be indicated by
the tire pressure warning system. Also, if you replace the compact spare tire
after the tire pressure warning light comes on, the light remains on.
■ When the compact spare tire is equipped
The vehicle becomes lower when driving with the compact spare tire com-
pared to when driving with standard tires.
■ If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle. Per-
form the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehicle.
Fit tire chains to the front tires.

When trouble arises
Check the degree of the tire damage.
A tire should only be repaired with
the emergency tire puncture
repair kit if the damage is caused
by a nail or screw passing through
the tire tread.• Do not remove the nail or screw
from the tire. Removing the
object may widen the opening
and prevent emergency repair
with the repair kit.
• To avoid sealant leakage, move the vehicle until the area of the puncture, if known, is positioned at the top of the tire.
■ In the following cases, the tire cannot be repaired with the emergency
tire puncture repair kit. Contact any authorized Toyota dealer or repairer,
or another duly qualified and equipped professional.
●When the tire is damaged due to driving without sufficient air pressure
● When there are any cracks or damage at any location on the tire, such as on
the side wall, except the tread
● When the tire is visibly separated from the wheel
● When the cut or damage to the tread is 4 mm (0.16 in.) long or more
● When the wheel is damaged
● When two or more tires have been punctured
● When more than 2 sharp objects such as nails or screws have passed
through the tread on a single tire
● When the sealant has expired

When trouble arises
Connect the bottle to the com-
pressor.
As shown in the illustration, insert
the bottle vertically into the com-
pressor to connect making sure
that the claw on the bottle’s neck is
hooked onto the cutout of the com-
pressor case.
Check the specified tire inflation pressure.
Tire inflation pressure is specified on the label on the driver’s side pillar as
shown. (→P. 461)
Start the hybrid system. ( →P. 201)

To inject the sealant and inflate
the tire, turn the compressor
switch on.
Inflate the tire until the specified
air pressure is reached.The sealant will be injected
and the pressure will surge,
and then gradually decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 minute
(15 minutes at low tempera-
ture) after the switch is
turned on.
Inject to specified air pres-
sure.• 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 infla-
tion pressure is reached.
• If the tire inflation pressure is still lower than the specified point
after inflation for 35 minutes with the switch on, the tire is too
damaged to be repaired. Turn the compressor switch off and
contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
• If the tire inflation pressure exceeds the specified air pressure, let out some air to adjust the tire inflation pressure.

Turn the compressor switch on
and wait for an approximately 5
seconds, and then turn it off.
Check the tire inflation pres-
sure.If the tire inflation pressure is
under 130 kPa (1.3 kgf/cm
2
or bar, 19 psi): The puncture
cannot be repaired. Contact
any authorized Toyota dealer
or repairer, or another duly
qualified and equipped pro-
fessional.
If the tire inflation pressure is 130 kPa (1.3 kgf/cm
2 or bar, 19 psi)
or higher, but less than the specified air pressure: Proceed to .
If the tire inflation pressure is the specified air pressure ( →P. 461):
Proceed to .
Turn the compressor switch on to inflate the tire until the specified
air pressure is reached. Drive for about 5 km (3 miles) and then
perform .
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.
Store the bottle in the luggage compartment while it is connected to
the compressor.
Taking precautions to avoid sudden braking, sudden acceleration
and sharp turns, drive carefully at under 80 km/h (50 mph) to the
nearest authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional for tire repair or replacement.
