4-3. Do-it-yourself maintenance
NOTICE
■ Repairing or replacing tires, wheels and tire pressure warning
valves and transmitters
When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pressure
warning valves and transmitters may be damaged if not handled cor-
rectly.
■ To avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire air 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 and wheels
Wheels with profile tires like 17- and 18-inch tires may cause greater
damage than usual to the tire wheel when receiving 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 pot holes, uneven pavement, curbs and other road hazards.
Failure to do so can lead to severe tire and wheel damage.
■ If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
