'05 MATRIX_U (L/O 0409) For details about the side wall of the tire and the Certification Label, see pages 195 and 197. CAUTION Observe the following instructions. Otherwise, an accident may occur resulting in death or serious injuries. D Do not mix radial, bias belted, or bias −ply tires on your vehicle, as this may cause dangerous handling characteristics resulting in loss of control. D Do not use tires other than the manufacturer's recommended size, as this may cause dangerous handling characteristics resulting in loss of control. D Four −wheel drive models: Do not use tires of different brands, sizes, construction or tread patterns, as this may cause dangerous handling characteristics resulting in loss of control. Toyota recommends all four tires, or at least both of the front or rear tires be replaced at a time as a set. See "If you have a flat tire" on page 231 for tire change procedure. When a tire is replaced, the wheel should always be balanced. An unbalanced wheel may affect vehicle handling and tire life. Wheels can get out of balance with regular use and should therefore be balanced occasionally. When replacing a tubeless tire, the air valve should also be replaced with a new one. Initial adjustment of the tire pressure warning system is necessary after you have rotated your tires. See "Tire pressure warning system" on page 128 in Section 1 −6. 282 2005 MATRIX from Sep.
