Eco-driving function Chapter 05 Eco-driving function This navigation system is equipped with an Eco-driving function that can be used to estimate whether you are driving in an environmentally friendly way. This chapter describes this function. ! The fuel mileage calculated is based on a theoretical value determined from vehicle speed and position information from the navigation system. The fuel mileage displayed is only a reference value, and does not guarantee the mileage displayed can be obtained. ! The Eco-driving functions are an estimate of the real time fuel consumption to average fuel consumption ratio and is not an actual value. ! The Eco-driving functions and calculations take into consideration the location of the GPS position and speed of the vehicle in determining a value. Displaying "Eco Graph" This function estimates approximate fuel mileage based on your driving, compares that with your average fuel mileage in the past, and displays the results in a graph. The graph appears when the map display is set to "Eco Graph". 1 Display the "Map Settings" screen. = For details, refer to Displaying the "Map Settings" screen on page 154. 2 Touch [View Mode].
