This navigation system is equipped with an
Eco-driving function that can be used to esti-
mate whether you are driving in an environ-
mentally friendly way.
This chapter describes this function.
p 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.
Displaying “Eco Graph”
This function estimates approximate fuel mile-
age based on your driving, compares that with
your average fuel mileage in the past, and dis-
plays the results in a graph.
The graph appears when the map display is

1 Eco 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.

3 Average 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

direction of +, the better the fuel mileage.
