This navigation system is equipped with eco-
friendly driving functions that can be used to
estimate whether you are driving in an envir-
onmentally 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 timefuel 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 andspeed of the
vehicle in determining a value.
Checking the eco-friendly
driving status
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
set to “Eco Graph”.

1 Eco Score
The result of the comparison of your past
average fuel mileage and current average
fuel mileage appears as a value from
0.0Pts (points) to 10.0Pts. 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.

is set to “Off” or when no route is set.
3 Average fuel mileage comparison graph
Displays a comparison of the averagefuel
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.
