When trouble arises
■The tire pressure warning light may come on due to natural causes (if
equipped)
The tire pressure warning light may come on due to natural causes such as
natural air leaks or tire inflation pressure changes caused by temperature. In
this case, adjusting the tire inflation pressure will turn off the warning light
(after a few minutes).
■ When a tire is replaced with a spare tire (vehicles with the tire pressure
warning system)
Vehicles with compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and transmitter. If a tire goes flat, the tire pres-
sure warning light will not turn off even though the flat tire has been replaced
with the spare tire. Replace the spare ti re with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will go off after a few
minutes.
Vehicles with full-size spare tire: T he spare tire is also equipped with a tire
pressure warning valve and transmitter. The tire pressure warning light will
turn on if the tire inflation pressure of the spare tire is low. If a tire goes flat,
the tire pressure warning light will not turn off even though the flat tire has
been replaced with the spare tire. Replace the spare tire with the repaired tire
and adjust the tire inflation pressure. The tire pressure warning light will go off
after a few minutes.
■ Conditions that the tire pressure warning system may not function prop-
erly (if equipped)
 P. 533
■ If the tire pressure warning light frequently comes on after blinking for
1 minute (if equipped)
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 retailer or Toyota authorized repairer, or any reliable
repairer.
■ Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location
or audio sound.

WARNING
■When the electric power steering system warning light comes on
When the light comes on yellow, the assist to the power steering is
restricted. When the light comes on red, the assist to the power steering is
lost and handling operations of the steering wheel become extremely
heavy. When steering wheel operations are heavier than usual, grip the
steering wheel firmly and operate it using more force than usual.
■ If the tire pressure warning light comes on (vehicles with the tire pres-
sure warning system)
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 emergency tire puncture repair kit: If the tire pressure warn-
ing light comes on even after tire inflat ion pressure adjustment, it is proba-
ble that you have a flat tire. Check the tire s. If a tire is flat, repair the flat tire
by using emergency tire puncture repair kit.
● Vehicles with 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 flat, change it with the spare tire and have
the flat tire repaired by the nearest any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
● 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 (vehicles with the tire
pressure warning system)
The tire pressure warning system may not activate immediately.
NOTICE
■ To ensure the tire pressure warning system operates properly (vehi-
cles with the tire pressure warning system)
Do not install tires with different specif ications or makers, as the tire pres-
sure warning system may not operate properly.

■If the tire is inflated to more than the specified air pressure
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air release cap from the
hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, and then turn
it off. Check that the air pressure indicator shows the specified air pressure.
( P. 665)
If the air pressure is under the designated pressure, turn the compressor
switch on again and repeat the inflation procedure until the specified air
pressure is reached.
■ The valve of a tire that has been repaired
After a tire is repaired with the emer gency tire puncture repair kit, the valve
should be replaced.
■ After a tire is repaired with the emergency tire puncture repair kit (vehi-
cles with the tire pressure warning system)
● The tire pressure warning valve and transmitter should be replaced.
● Even if the tire inflation pressure is at the recommended level, the tire pres-
sure warning light may come on/flash.
■ Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whose expiry date
has already passed. Otherwise, repairs conducted using the emergency tire
puncture repair kit may not be performed properly.
Install the air release cap to the end of
the hose and push the protrusion on the

When trouble arises
■The compact spare tire (if equipped)
● 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. 665)
■ When using the compact spare tire (vehicles with the tire pressure warn-
ing system)
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 (if equipped)
The vehicle height may become lower when driving with the compact spare
tire compared to when driving with standard tires.
■ If you have a flat front tire on a road covered with snow or ice (vehicles
with compact spare tire)
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.
