FORD 2011 Edge v.3 - Manual (Page 268)

Activating/deactivating collision warning system
To turn the warning system and/or chime on or off and set the warning
sensitivity <– –>, refer to Message center in the Instrument Cluster
chapter.
Note: If the system cannot be turned off in a MyKey™ equipped vehicle,
refer to MyKey™ in the Locks and Security chapter for more
information.
Note: If collision warnings are perceived as being too frequent or
disturbing then the warning sensitivity can be reduced, though the
manufacturer recommends using the highest sensitivity setting where
possible. Setting lower sensitivity would lead to fewer and later system
warnings. Refer to the Message center in the Instrument Cluster
chapter for instructions on reducing the sensitivity.
BLIND SPOT MIRRORS (IF EQUIPPED)
Blind spot mirrors have an integrated convex spotter mirror built into
the upper outboard corner of the outside mirrors. They are designed to
assist the driver by increasing visibility along the side of the vehicle. For
more information on your side view mirrors, refer to Exterior mirrors in
the Driver Controls chapter.
