The electric parking brake system AUTO function (shift-linked function) automatically releases the parking brake when the following conditions are met: 1) Engine switch is on (IG), 2) brake pedal is depressed, and 3) shift lever is moved out of P. When the shift lever is moved to P with these conditions met, the function automatically locks the parking brake. The electric parking brake system AUTO (shift-linked function) automatically engages the parking brake when the shift lever is moved to P and disengages the parking brake when the shift lever is moved out of P when the engine switch is on (IG) and the brake pedal is depressed.
