Maintenance and care
Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread.
Check the spare tire condition and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “” mark, etc.,
molded into the sidewall of each tire.
Replace the treadwear indicators are showing on a tire.
Rotate the tires in the order
shown.
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initialize the tire
pressure warning system after
tire rotation.
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.

When trouble arises
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Push-
ing the tire pressure warning reset switch will not turn off the tire pressure
warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflation pressure changes caused by temper-
ature. 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
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. 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.
■If the tire pressure warning system is not functioning
P. 4 4 8
■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.
■Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location
or audio sound.

WARNING
■When using the compact spare tire
●Remember that the spare tire provided is specifically designed for use
with your vehicle. Do not use your spare tire on another vehicle.
●Do not use more than one compact spare tire simultaneously.
●Replace the spare tire with a standard tire as soon as possible.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-
ing operations that cause sudden engine braking.
■When the compact spare tire is attached
The vehicle speed may not be correctly detected, and the following sys-
tems may not operate correctly:
■Speed limit when using the compact spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Fail-
ure to observe this precaution may lead to an accident causing death or
serious injury.
