An exterior vehicle mirror system has a vehicle mountable support and a
support arm. A mirror housing is movable along the support arm between
the support and a distal end. An electrically powered mirror unit adjust
mechanism can adjust the mirror unit about horizontal and vertical axes.
An electrically powered pivoting and extending mechanism pivots the
support arm about the support between an extended position and a position
folded against a vehicle side. An electronic control system controls
movement of the mirror housing along the support arm, and folding of the
support arm, independent of an adjustment of the mirror unit. The
electronic control system comprises a memorized position for the powered
pivoting and extending mechanism.
