    My wife mainly drives our 2005 Prius so I cannot say day to day what it does, but here goes.

    Does the Master Warning Light (red triangle with exclamation point) always come on briefly (less than a second) at start up? Just wondering if I should be concerned.

    Thanks.

    Yes. All of the dash lights turn on for a second, presumably to demonstrate that they are working.
