- Turn the ignition key to the ON position (the engine is off, or the high-voltage system is disengaged for an electric vehicle).
- Depress the brake pedal repeatedly to release air pressure from the brake system.
- When the air pressure drops below the preset level, the emergency buzzer activates, the low air brake pressure warning lamp illuminates, and the LEDs on the Intellipark parking brake control valve flash off and on.
