On this vehicle, the "C" indicates circle calibration. According to Toyota, the following must be done:
1)Stop the vehicle in an area where it is safe to drive in a circle.
2)Press and hold the auto button for approximately ten seconds or until a C appears
3)At a speed of five mph or less, drive the vehicle in a circle until the direction is displayed
NOTE: There are certain elements which can cause this process to fail. The following is a list of things to check, but potential problems are not limited to said list.
A) The vehicle is stopped while driving in a circle prior to reset.
B) The surface is not flat.
C) The Earth's natural magnetic field is interfered with by such things as:
* Underground wiring
* Between large structures
* Nearby steel towers
* An open car door
D) There is a magnet or metal object near the mirror.
Let me know if this helps.
