A warning chime will sound if the parking brake is set, the ignition is on, and the vehicle speed is greater than 5 mph (8 km/h). The brake light will come on and stay on until the parking brake is released. See Brake System Warning Light on page 222 for more information. To release the parking brake, hold the regular brake pedal down with your right foot and push the parking brake pedal down with your left foot. When you lift your left foot, the parking brake pedal will follow it to the released position.
