FORD 2009 F-150 v.1 - Manual (Page 77)

Note: 10 or more switch activations within one minute, or repeated
folding/unfolding of the mirrors while holding the switch rearward during
full travel, may cause the system to disable the fold/unfold function to
protect motors from overheating. Should this occur, wait approximately
three minutes with the vehicle running and up to 10 minutes with the
vehicle off, for the system to reset and for function to return to normal.
Heated outside mirrors (if equipped)
Heated mirrors remove ice, mist and
fog. To activate the heated mirrors,
press the rear defrost button
R
located on the climate control panel.
Refer to Rear window defroster in
the Climate Controls chapter for
more information.
On vehicles not equipped with rear defrost, press the heated mirror
control
located on the climate control panel. For more information
refer to the Climate Controls chapter.
Note: If your vehicle is equipped with the Auto dimming feature, the
mirror glass is thicker and will take longer to defrost.
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.
Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.
Exterior mounted mirror turn signal indicator (if equipped)
When the vehicle turn signal is
activated, the lower portion of the
mirror housing will blink.
This feature provides an indicator to
the driver that the vehicle turn
signal is working properly.
