WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
● Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
● Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.
■ When initializing the tire pressure warning system (vehicles with a tire
pressure warning system)
Do not operate the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.

■ When the tire pressure warning light comes on (vehicles with a tire pres-
sure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 596, 614
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
● Check the tire inflation pressure and adjust to the appropriate level.
● If the warning light does not go out even after several minutes, check that
the tire inflation pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.
■ The tire pressure warning light may come on due to natural causes
(vehicles with a tire pressure warning system)
The tire pressure warning light may come on due to natural causes such as
natural air leaks and 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 (include compact spare tire)
(vehicles with a tire pressure warning system)
The spare tire (include compact spare tire) is not equipped with a tire pres-
sure warning valve and transmitter. If a tire goes flat, the tire pressure warn-
ing light will not turn off even though the flat tire has been replaced with the
spare tire. Replace the spare tire wi th the repaired tire and adjust the tire
inflation pressure. The tire pressure warning light will go off after a few min-
utes.
■ Conditions that the tire pressure warning system may not function prop-
erly (vehicles with tire pressure warning system)
 P. 513
■ If the tire pressure warning light frequently comes on after blinking for 1
minute (vehicles with a tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1 min-
ute when the engine switch is turned on, have it checked by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

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 retailer or Toyota authorized r epairer, or any reliable repairer. 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 (vehicles with a 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 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 authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
● 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. ( P. 596)
● 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 a 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 a 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.

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 .
Store the compressor in the luggage compartment.
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 retailer or Toyota authorized repairer, or
any reliable repairer for tire repair or replacement.
■ If the tire is inflated to more than the specified air pressure
Check that the air pressure indicator shows the specified air pressure.
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.
■ After a tire is repaired with the emergency tire puncture repair kit
● 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.
Press the button to let some air out.1

■The full-size spare tire (if equipped)
● On vehicles with a tire pressure warning system: The full-size spare tire is
identified by a label with temporary use only information.
Use the full-size spare tire temporarily, and only in an emergency.
● Make sure to check the tire inflation pressure of the full-size spare tire.
( P. 659)
■ 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. 659)
■ When using the spare tire (include compact spare tire) (vehicles with a
tire pressure warning system)
As the spare tire is not equipped with a tire pressure warning valve and trans-
mitter, low inflation pressure of the spare tire will not be indicated by the tire
pressure warning system. Also, if you replace a flat tire with the 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 vehi-
cle.
Fit tire chains to the front tires.
