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.
The fuel mileage calculated is based on a theo-
retical value determined from vehicle speed
and position information from the navigation
system. The fuel mileage displayed is only a re-
ference value, and does not guarantee the
mileage displayed can be obtained.

age based on your driving, compares that with
your average fuel mileage in the past, and dis-
plays the results in a graph.
