05Eco-friendly driving functions

This navigation system is equipped with eco- friendly driving functions that can be used to estimate whether you are driving in an environmentally friendly way.

This chapter describes these functions.

!The fuel mileage calculated is based on a theoretical value determined from vehicle speed and position information from the navigation system. The fuel mileage dis- played is only a reference value, and does not guarantee the mileage displayed can be obtained.

!The eco-friendly driving functions are an es- timate of the real time fuel consumption to average fuel consumption ratio and is not an actual value.

!The eco-friendly driving functions and cal- culations take into consideration the loca- tion of the GPS position and speed of the vehicle in determining a value.

Checking the eco-friendly driving status

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”.

1Eco Score

The result of the comparison of your past average fuel mileage and current average fuel mileage appears as a value from

0.0 Pts (points) to 10.0 Pts. The higher the value, the better the fuel mileage when compared to past route guidance.

The green gauge indicates the current score, and the gray gauge indicates the best score to date.

The “Eco Score” is updated every 5 min- utes.

p This is not displayed when “Eco Score” is set to “Off” or when no route is set.

2Best Score

Displays the best score to date.

p This is not displayed when “Eco Score” is set to “Off” or when no route is set.

3Average fuel mileage comparison graph Displays a comparison of the average fuel mileage up to the point the navigation sys- tem was last stopped (past average fuel mileage) and the current average fuel mile- age. The display is updated every 3 sec- onds. The more the value moves in the direction of +, the better the fuel mileage. There are three different graph bars.
