STARTING AND DRIVING To initialize the system, perform the following: 1. Park the vehicle in a safe place and select the engine switch in "OFF" mode. 2. Adjust the pressure of all the installed tires to the specified cold tire inflation pressure level. (See "Tire and wheels" on pages 542 and 546.) 3. Select the engine switch in "IG−ON" mode. 4. Push and hold the tire pressure warning reset switch until the tire pressure warning light blinks slowly three times and the message "PRESSURE INITIAL" appears on the multi−information display. 5. Wait for a few minutes with the engine switch in "IG−ON" mode, and then select the engine switch in "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. G31007 If the tire pressure warning light does not blink slowly three times and the message "PRESSURE INITIAL" does not appear on the multi−information display 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. 447
