06 06.02 REPLACING TIRES AND WHEELS When replacing the tires and wheels, be sure to install tire pressure warning valves and transmitters. ID codes on the tire pressure warning valves and transmitters are registered in the tire pressure warning ECU. When replacing a tire pressure warning valve and transmitter, it is necessary to register the ID code of tire pressure warning valve and transmitter. Have the ID code registered by your Toyota dealer. If the ID code is not registered, the system will not work properly. After about 1 hour, the tire pressure warning light blinks (comes on after blinking for 1 minute) to indicate a system malfunction. D When changing the tire inflation pressure by changing traveling speed or load weight, etc. D When changing the tire size. u16051 To initialize the system, perform the following: 1. Park the vehicle in a safe place and turn the ignition key to the "OFF" position. 2. Adjust the pressure of all the installed tires (including spare) to the specified cold tire inflation pressure level. (See "Tires" on page 462 in Section 8.) 3. Turn the ignition key to the "ON" position. 4. Push and hold the tire pressure warning reset switch until the tire pressure warning light blinks slowly three times. 5. Wait for a few minutes with the ignition key "ON", and then turn the ignition key to the "OFF" position. If you push the tire pressure reset switch while vehicle is moving, initialization is not performed. If you push the tire pressure reset switch accidentally and initialization is performed, adjust the tire inflation pressure to the specified level and initialize the system again. TIRE PRESSURE SWITCH WARNING RESET NOTICE When the tires or tire pressure warning valves and transmitters must be replaced, have them replaced by your Toyota dealer. The tire pressure warning valves and transmitters will be affected by the installation or removal of tires. When initializing the system, the present tire inflation pressure is stored as standard. The tire pressure warning system determines decreased air pressure by comparing the present and the standard tire inflation pressures. When you change the set tire inflation pressure, it is necessary to initialize the tire pressure warning system. D When rotating the tires on vehicles differing with front and rear tire inflation pressures. 2007 SEQUOIA from Sep. '06 Prod. (OM34457U) 205
