Dealer Email: Momentary activation of the electronic parking brake (EPB) can occur in limited circumstances if the driver moves the shift lever from the drive position into the manual downshift position when a rigid object of a specific size is placed in the EPB switch finger well. Momentary activation while driving will result in the vehicle slowing slightly, warning lights appearing on the instrument panel, a ?PKB Applied? display message, and audible buzzing. Any authorized Toyota dealer will install a cover to reduce the size of the EPB switch opening.
