NOTICE
■
Repairing or replacing tires, wheels, tire pressure warning valve
and transmitters and tire valve caps
●
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitters, contact your Toyota dealer as the tire pressure
warning valve and transmitters may be damaged if not handled cor-
rectly.
●
Make sure to install the tire valve caps. If the tire valve caps are not
installed, water may enter the valves of the tire pressure warning valve
and transmitters and the valves may become stuck.
●
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 valve and transmit-
ters
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 replacing the tire. (P. 446)
■
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 the tires. In addition, driving on rough roads
may cause damage to the tires themselves, as well as the vehicle's
wheels and body.
■
Low profile tires (vehicles with 18 or 19-inch wheels)
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention
to the following:
●
Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
●
Avoid potholes, uneven pavement, curbs and other road hazards. Fail-
ure to do so may lead to severe tire and wheel damage.
■
If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
