  • The air pressure falls below the preset level, which is 65 psi (448 kPa).

  • The parking brake is set with the vehicle moving at a speed greater than 2 mph (3 km/h).

  • The coolant temperature rises above 253°F (123°C) and the check engine and stop engine lights illuminate. When the coolant temperature falls below 244° (118°C) the emergency buzzer and stop engine light will turn off.
