1. A handle assembly for a door of a vehicle, said handle assembly comprising:

  • a base portion mounted at or incorporated into a structure of the door of the vehicle;

    a handle portion movable relative to said base portion, wherein said handle portion is movable between a recessed position, where said handle portion is at least partially recessed at said base portion so as to be not readily graspable by a user, and a partially extended position, where said handle portion extends partially outward from said base portion to be graspable by the user;

    wherein, when said handle portion is at said partially extended position, said handle portion is manually movable further outward from said base portion to open the door of the vehicle;

    a control operable to move said handle portion between said recessed position and said partially extended position;

    wherein said control controls operation of a motor of an electrically operable actuator of said handle assembly and wherein operation of said motor moves said handle portion between said recessed position and said partially extended position;

    wherein said control controls said motor of said actuator to move said handle portion from said recessed position to said partially extended position responsive to a trigger;

    wherein said trigger comprises at least one of (a) a signal from a passive entry device, (b) a signal from a remote transmitting device and (c) a signal indicative of the user actuating a door unlock button of the vehicle;

    wherein said actuator provides a manual override that allows the user to manually move said handle portion relative to said base portion, wherein said manual override is provided via at least partial disengagement or slippage of gears of said actuator when the user urges said handle portion inwards towards said base portion; and

    wherein, responsive to determination of a lockout condition, said control limits movement of said handle portion from said recessed position towards said partially extended position irrespective of the trigger.
