After the most recent ice storm, I received an email from a long time client (thanks Ryan C!) who advised me of the function of the power folding mirrors on his new CX-5.

The power folding mirrors on our CX-series vehicles are made to fold-in when the vehicle is turned off, and they fold out for normal use when the vehicle is re-started.

This is all well and good until they are covered in thick ice, which would prevent them from operating properly.  Here is the excerpt from the owners manual of a CX-5 which will allow you to disable this function if needed.
