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.

driving status
This function estimates approximate fuel mile-
age based on your driving, compares that with

plays the results in a graph.
The graph appears when the map display is

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.

utes.

direction of +, the better the fuel mileage.
