About the Eco score
● After starting off, Eco score display does not start until the vehicle speed
exceeds approximately 20 km/h (12 mph).
●
In addition to the vehicle driving status, the Eco score also evaluates the air
conditioning system usage condition (→P. 149). The score displayed when
the hybrid system stops is the total result of the driving status after the
hybrid system starts and the air conditioning usage condition.
