■ When to replace your vehicle's tires
Tires should be replaced if:
● The treadwear indicators are showing on a tire.
● You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating internal damage
A tire goes flat repeatedly or cannot be properly repaired due to the size or
●
location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
Replacing tires and wheels (vehicles with tire pressure warning system)
■
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving for
about 10 minutes, the tire pressure warning light blinks for 1 minute and stays
on to indicate a system malfunction.

Tire life

■
Any tire over 6 years old must be checked by a qualified technician even if it
has seldom or never been used or damage is not obvious.
Routine tire inflation pressure checks (vehicles with tire pressure warn-
■
ing system)
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your routine
of daily vehicle checks.
Initializing the tire pressure warning system (vehicles with tire pressure
■
warning system)
Initialize the system with the tire inflation pressure adjusted to the specified
level.
If the tread on snow tires wears down below 4 mm (0.16 in.)
■
The effectiveness of the tires as snow tires is lost.
■ If you press the tire pressure warning reset switch accidentally (vehicles
with tire pressure warning system)
If initialization is performed, adjust the tire inflation pressure to the specified
level and initialize the tire pressure warning system again.
