Failure to do so may cause damage to parts of the drive train, as well as dangerous handling characteristics, which may lead to fatal or injury accidents. l Do not mix tires of different makes, models, tread patterns or tread- wear. l Do not use tire sizes other than those recommended by Toyota. l Do not mix radial, bias-belted, or bias-ply tires. l Do not mix summer, all season and winter tires. l Do not use tires that have been used on another vehicle. l Do not use tires if you do not know how they were used previously. n When initializing the tire pressure warning system Do not push the tire pressure warning reset switch without first adjusting the tire inflation pressure to the specified level.
