Beside the left wall of the foot well (where the pedals are) is a small square pedal. This is your parking brake. To set it, just ush down to set the brakes.
To release the brakes, there is a handle just at the bottom edge of the dashboard in the same area. Grasp this handle and give it a pull. Ity will make a bit of noise, but that's okay, it is supposed to.
Make sure you are pulling the correct handle as the hood release is in that area also.
They are both marked with what they are.
