CAUTION
 When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dan-
gerous handling 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 tires (radial, bias-belted or bias-ply
tires).
 Do not mix summer, all season and snow tires.
 Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
NOTICE
 Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
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.
 If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
