For the SOS Emergency Assistance and Call Mitsubishi Motor Assist buttons inside the vehicle to work, you must first start the vehicle engine to power the telematics control unit.
In Outlander and Outlander PHEV vehicles, the Information Assistance button is the same as the "Call Mitsubishi Motor Assist" button, which is found on the infotainment menu screen. Press the "Info." button, then press "MITSUBISHI CONNECT Services."
