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: CAUTION If the "VSC" warning light remains on together with the red brake system warning light, immediately stop your vehicle at a safe place and contact your Toyota dealer. In this case, not only the vehicle stability control system will fail but also the vehicle will become extremely unstable during braking. (l) Key Reminder Buzzer This buzzer reminds you to remove the key if you open the driver's door when the hybrid system is off and the key is inserted into the key slot. (m) Shift Position Reminder Buzzer This buzzer will sound if the driver's door is opened while the hybrid transaxle is in "N", "D" or "B". CHECKING SERVICE REMINDER INDICATORS (except the low fuel level indicator light) 1. Apply the parking brake. 2. Open one of the doors. The open door warning light should come on. 3. Close the door.

At this time, all the bulbs are checked in self−diagnosis mode. All the service reminder indicators except the open door warning light come on.

There may be the case that the yellow brake system, "ABS" and "VSC" warning lights stay on for about 60 seconds after the "IG−ON" mode is enabled. It is normal if they go out after a while.
