First - stay calm, activate your hazard lights and try to pull over to a safe location on the side of the road or into a parking lot. If possible, choose a place that's well-lit and visible to others.
To conserve any remaining power, turn off non-essential systems such as air conditioning, heating, and infotainment. Once you are in a safe location, confirm that you are out of charge and/or unable to operate your EV.
Please contact your zTrip road supervisor for assistance.
