I was driving in a rather steep incline and a car was in the way, so i braked. I was going to pass the car but the space is rather tight, so I ease off the brake pedal to creep up slowly. The car didn't move forward nor roll backward, and when I press back the brake pedal, it was stiff as if the Auto-H is active. I press the gas pedal and the car move forward. The thing is, I didn't activate the Auto hold function nor I see the symbol on the instrument panel.
Is there a feature i don't know about (hillstart assist?) or is it a malfunction? (hope not)
