Driver's side, left of the steering column, just where the lower dash cover ends — below and behind the hood release lever. No cover over the port. A flashlight helps; a dongle plugged in here protrudes into the driver's left leg space.

OBD port location in a Toyota Prius XW30

XW30 2010–2015

US cars are left-hand drive: the 16-pin OBD socket is up under the lower dash, left of the steering column, low down near the driver's knee bolster and close to the brake pedal. The connector faces downward toward the floor, so it sits out of direct sight - get your head into the footwell and look up at the underside of the plastic knee panel, or feel for it just behind the lower edge of that panel. Same position on every US Prius trim (One/Two/Three/Four/Five). Note the port on the later Gen 4 (2016+) car moved further left above the parking-brake pedal; on this Gen 3 it is closer in to the steering column.

OBD port location in a Toyota Prius XW20

XW20 2004–2009

LHD: Below the dashboard on the driver's side, just left of the steering column, tucked up under the lower dash trim above the driver's left knee. The 16-pin connector (labelled DLC3) faces downward and is immediately visible when you crouch and look up from the footwell. Same location on all XW20 trims, smart-key and non-smart-key cars alike. This generation was sold left-hand drive in North America only, so there is no RHD position to document for this market.
