FORD 2003 F-550 v.2 - Manual (Page 55)

Heated outside mirrors (if equipped)
Both main mirrors are heated
automatically to remove ice, mist
and fog. The mirrors are
automatically activated when the
vehicle is started.
Note: The mirrors may be hot to
the touch but will not burn. This is
a normal condition.
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.
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.
Signal mirrors (if equipped)
When the turn signals of the vehicle
are activated, the outer portion of
the appropriate mirror housing will
blink amber.
The turn signal feature can be seen
by other drivers who may approach
from the rear of the vehicle.
