(j) Engine Oil Replacement Reminder Light (for vehicles sold in the U.S.A.) This light acts as a reminder to replace the engine oil. This light will come on when the "IG−ON" mode is enabled, and will go off after about a few seconds. When you drive for about 7200 km (4500 miles) after engine oil replacement, this light illuminates for about 3 seconds and then flashes for about 12 seconds when the hybrid system is in the "IG−ON" mode. If you continue driving without engine oil replacement, and if the driving range exceeds 8000 km (5000 miles), the light will come on after the "IG−ON" mode is enabled. 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 the oil as soon as possible. The system must be reset after the engine oil replacement. Reset the system by the following procedure: 1. Press the "POWER" switch to the "OFF" mode with the odometer reading shown. (For details, see "Odometer and two trip meters" on page 123.) 2. Press the "POWER" switch twice to select the "IG−ON" mode while holding down the trip meter reset button. Hold down the button for at least 5 seconds. The odometer indicates "000000" and the light goes off. If the system fails to reset, the light will remain flashing. (k) "VSC" Warning Light This light warns that there is a problem somewhere in the vehicle stability control system. The light will come on when the "IG−ON" mode is enabled and will go off after the "READY" light comes on. 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: D The warning light does not come on after the "IG−ON" mode is enabled. "READY" light comes on. D The warning light remains on after the D The warning light comes on while you are driving. 131
