04 SIENNA_U (L/O 0408) (k) "VSC" Warning Light This light warns that there is a problem somewhere in the vehicle stability control system or traction control system. The light will come on when the ignition key is turned to "ON" and will go off after a few seconds. If the light comes on while driving, the system does not work. However, as conventional braking operates when applied, there is no problem to continue your driving. In the following cases, contact your Toyota dealer: (l) Low Tire Pressure Warning Light This light warns that the tire pressure of any one of the tires is critically low. The light comes on when the ignition key is turned to the "ON" position. It goes off after a few seconds. This indicates that the low tire pressure warning system is functioning properly. If the light comes on while driving, adjust tire inflation pressure to the specified level. (See "Tires" on page 491 in Section 8.) After the tire inflation pressure is adjusted, the light should go off after driving at least 30 km/h (19 mph) for some time. If the light still remains or blinks once every second, have the low tire pressure warning system checked at your Toyota dealer. If the light blinks twice every second, the low tire pressure warning system needs to be initialized. For details, see "Tire pressure warning system" on page 188 in Section 1 −6. (m) Low Windshield Washer Fluid Level Warning Light The light warns that the windshield washer fluid level is too low. Add washer fluid at your earliest opportunity. (For instructions, see "Adding washer fluid" on page 479 in Section 7−3.) (n) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.) This light reminds you when to replace the engine oil. This light will come on when the ignition key is turned to "ON" and will go off after about a few seconds. When you drive for about 8000 km (5000 miles) after the engine oil replacement, this light illuminates for about 3 seconds and then flashes for about 12 seconds with the ignition key turned to the "ON" position. If you continue driving without replacing the engine oil, and if the distance driven exceeds 12000 km (7500 miles), the light will come on after the ignition key is turned to "ON" position. The light will remain on thereafter. If the light is flashing, we recommend that you replace the engine oil at an early opportunity depending on the driving and road conditions. If the light comes on, replace it as soon as possible. D The warning light does not come on after the ignition key is turned to "ON". D The warning light remains on after the ignition key is turned to "ON". D The warning light comes on while driving.
