FORD 2004 F-550 v.2 - Manual (Page 56)

Heated outside mirrors (if equipped)
The main mirror glass is heated automatically to remove ice, mist and
fog and activates when the vehicle is started.
Note: The mirrors may be hot to the touch but will not burn. This is a
normal condition.
Type A
The mirror heating elements are
designed to operate regardless of
the geographic location of the
vehicle. There is no switch to turn
on, or other operator involvement
required other than to start the
vehicle.
Type B
The spotter mirror, below the main
mirror, is not heated and must be
adjusted manually.
Do not remove ice from the mirrors with a scraper or attempt to
readjust the mirror glass if it is frozen in place. These actions
could cause damage to the glass and mirrors.
Mirror mounted side turn signal indicator (if equipped)
When the vehicle turn signals are
activated, the outer portion of the
mirror housing will blink amber.
The turn signal feature can be seen
by other drivers who may approach
from the rear of the vehicle.
