2006 Lexus GS 300 Owners Manual - Page 465

STARTING AND DRIVING To initialize the system, perform the following: 1. Park the vehicle at a safe place and apply the parking brake. Stop the engine. 2. Adjust the pressure of all the installed tires to the specified level. (See "Tires and wheels" on pages 534 and 537.) 3. Start the engine. 4. Push and hold the reset switch until the low tire pressure warning light blinks three times, and the message "PRESSURE INITIAL" appears on the multi −information display. Do not turn the engine off for about 20 minutes until initialization is complete. When initializing the system, make sure the low tire pressure warning light blinks three times and the message "PRESSURE INITIAL" appears on the multi−information display. If the warning light does not blink three times and the message does not appear on the multi−information display, initialization failed and the tire pressure warning system will not function properly. In this case, initialize the system again. Do not push the reset switch without adjusting the tire inflation pressure to the specified level. Otherwise, the low 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. If you push the reset switch while the vehicle is moving, initialization is not performed. If the low tire pressure warning light does not blink and the message does not appear on the multi−information display when you push and hold the reset switch, have the tire pressure warning system checked at your Lexus dealer. 441 G31007
