Submenus are:
■Shift indication : Current gear is
indicated inside an arrow. The

upshifting for fuel saving reasons.
Eco index display : The current fuel
consumption is indicated on a segment display. For economical
driving adapt your driving
characteristic to keep the filled
segments within the Eco area. The
more segments are filled, the
higher the fuel consumption.
Simultaneously the current
consumption value is indicated.
■ Top Consumers : List of top comfort
consumers currently switched on is displayed in descending order. Fuel
saving potential is indicated. A
switched off consumer disappears
from the list and the consumption value will be updated.
During sporadic driving conditions,
the engine will activate the heated
rear window automatically to

over a distance of 50 miles. Filled
segments display the consumption
in 5 mile steps and shows the effect of topography or driving behaviour
on fuel consumption.
