'05 TUNDRA_U (L/O 0504) Parking brake When initializing the system, make sure the low tire pressure warning light blinks three times. If the warning light does not blink three times, 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 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 when you push and hold the reset switch, have the low pressure warning system checked at your Toyota dealer.
