ticularly economicaldriving style.Dependin g
on the driving situation, uptotwo areas may
light upsimultaneously.
At the beginning ofthe journey, thethree
outer areas areempty andfillup asaresult of

more econom icaldriving style.Ifthe three
outer areas arecompletely filledatthe same

In addition todriving style,theactual con-
sumption isaffect edbyother factors,such as:

R active electric alconsumer s
These factorsarenot included inthe ECO dis-

On long journeys atac onst antspeed, e.g.on

The ECO display summarizes thedriving style
from thestart ofthe journey toits completion .
Therefore, therearemore marked changes in

If you inten dtom ount snow chains, please
bear thefollowing pointsinmind:
R Snow chains maynotbemounted onall
