## Abstract

A system for a vehicle includes control system configured to acquire a first indication regarding a slope of the vehicle at a current location, acquire a second indication regarding a grade of the vehicle at the current location, and generate a graphical user interface providing (a) a slope indicator indicating whether the slope of the vehicle is within an operational slope range or a nonoperational slope range and (b) a grade indicator indicating whether the grade of the vehicle is within an operational grade range or a nonoperational grade range.
