STARTING AND DRIVING To initialize the system, perform the following: 1. Park the vehicle in a safe place and turn the ignition switch to the "OFF" position. 2. Adjust the pressure of all the installed tires to the specified cold tire inflation pressure level. (See "Tire and wheels" on page 420.) 3. Turn the ignition switch 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 switch "ON", and then turn the ignition switch to the "OFF" position. If you push the tire pressure reset switch while the 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. If the tire pressure warning light does not blink slowly three times when you push and hold the reset switch, initialization has failed and the tire pressure warning system may not work properly. In this case, initialize the system again. If initialization cannot be performed, have the system checked at your Lexus dealer. 31x609 CAUTION Do not push the reset switch without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal. 306
