Eco-driving function

05

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 dis- played 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 aver- age 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 de- termining 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”.

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

 

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.

mileage and the average fuel mileage

 

from the location the navigation system

 

was last started to the current driving lo-

 

cation.
