Maintenance and care
■When replacing wheels
The wheels of your Toyota 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. 517)
CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may re sult in loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing serious
injury or death.
■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.

NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warn-
ing 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.
