If you're in a crash where airbags deploy or (in certain vehicles) the fuel-pump shuts off, 911 Assist® with GPS uses your paired phone to make a 911 emergency call.* The microphone is on so anyone in the vehicle can speak to the operator, even if unable to reach the controls. 911 Assist is off by default, so you must change settings to turn it on or disable reminder alerts.27,28
