FORD 2013 Expedition v.2 - Manual (Page 162)

HEATED WINDOWS AND MIRRORS (IF EQUIPPED)
Heated Rear Window
Note: The vehicle must be running to use this feature.
Press the control to clear the rear window of thin ice and fog. Press the
control again within 15 minutes to switch it off. It turns off automatically
after approximately 15 minutes, or when you switch the ignition off.
Do not use razor blades or other sharp objects to clean the inside
of the rear window or to remove decals from the inside of the
rear window. This may cause damage to the heated grid lines.
Your warranty does not cover this damage.
Heated Exterior Mirror (If Equipped)
Note: Do not remove ice from the mirrors with a scraper or attempt to
readjust the mirror glass that has frozen in place. These actions could
cause damage to the glass and mirrors.
Note: Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.
Both mirrors heat to remove ice, mist and fog when you turn the rear
window defroster on.
