06 SIENNA_U (L/O 0603) Vehicles with vehicle stability control system-Initialization is completed after driving at the speeds of 30 km/h (19 mph) or over for more than one hour. If the following driving conditions are satisfied, initialization will be completed in about one hour. 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. When the warning light blinks twice every second while driving, you may be unable to reset the system. In this case, set the system again according to the above procedure. D The vehicle speed is between 50 km/h (31 mph) and 100 km/h (62 mph). D The roads are dry, smooth and straight. D The number of passengers is 1 or 2 (including driver). When initializing the system, make sure the low tire pressure warning light blinks three times. If the warning light does not blink three times, initializing will be failed and the tire pressure warning system will not function properly. 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. 212 2006 SIENNA from March '06 Prod. (OM45443U)
