Observe the following precautions to prevent accidents. Failure to do so
may cause damage to parts of the drive train as well as dangerous han-
dling 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 ti res (radial, bias-belted or bias-ply

NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure warning valves and transmitter may be damaged if not handled
correctly.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant is used, contact
your Toyota dealer or other qualified service shop as soon as possible. Make
sure to replace the tire pressure warning valve and transmitter when replac-
ing the tire. ( P. 538)
■
Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes. These conditions may cause losses in tire inflation pressure,
reducing the cushioning ability of th e tires. In addition, driving on rough
roads may cause damage to the tires themselves, as well as the vehi-
cle’s wheels and body.
■If tire inflation press ures of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves
and transmitters that allow the tire pressure warning system to provide
advanced warning in the event of a loss in tire inflation pressure. Whenever
wheels are replaced, the tire pressure warning valves and transmitters must
be installed. ( P. 538)
CAUTION
■When replacing wheels
● Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in a loss of handling control.
● Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
■ When installing the wheel nuts
●
Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
●Be sure to install the wheel nuts with
the tapered end faci ng inward. Install-
ing the nuts with the tapered end fac-
ing outward can cause wheel to
break and eventually cause a wheel
to come off while driving, which could
lead to an accident resulting in death
or serious injury.

■
Replacing tire pressure warning valves and transmitters
● Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by your Toyota
dealer or other qualified service shop. In addition, make sure to purchase
your tire pressure warning valves and transmitters at your Toyota dealer.
● Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with
non-genuine wheels.
