ECO display (example)
The ECO display gives you information on how
economical your driving style is. The ECO dis-
play assists you in achieving the optimum
driving style in terms of consumption, taking
the actual and selected conditions into con-
sideration. Your driving style can significantly
influence the vehicle's consumption.
The ECO display consists of three bars:
R Acceleration
R Constant
R Coasting
The percent value is the average value of the
three bars. The three bars and the average
value commence with a value of 50%. Ahigher
percentage indicates a mor eeconomical driv-
ing style.
The ECO display provides no information on
the actual fuel consumption. Afixed percent-
age value of the ECO display does not corre-
spond to a fixed consumption figure in
l/100km. Driving tips
