The
ECO display consistsofthree section s,
with aninner andouter area.Thesection scor-
respond tothe following threecategories: 0043
Acce
leration (evaluation ofall
acceleration processes):
R the outer areafillsupand the
inner arealights upgreen: moder-
ate acceleration ,especially at
higher speeds
R the outer areaempties andthe
inner areaisgray: sporty acceler-
ation 0044
Coasting
(evaluation ofall deceler-
ation processes):
R the outer areafillsupand the
inner arealights upgreen: antici-
patory driving, keeping yourdis-
tanc eand early release ofthe
accelerator. Thevehicle can
coast without useofthe brakes.
R the outer areaempties andthe
inner areaisgray: frequent heavy
braking 0087
Constant
(continuous evaluation
over theentir ejourney):
R the outer areafillsupand the
inner arealights upgreen: con-
stant speed andavoidance of
unnecessary accelerationand
deceleration
R the outer areaempties andthe
inner areaisgray: fluctuations in
speed The
three innerareas display thecurrent driv-
ing style andlight upgreen asaresult ofap ar-
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
econom icaldriving. Ahigher levelindicates a
more econom icaldriving style.Ifthe three
outer areas arecompletely filledatthe same
time, thedriver hasadopted themost eco-
nomical drivingstyleforthe selected settings
and prevailing conditions.TheECO display
border lightsup.
The ECO display doesnotindicate theactual
fuel consumpt ion.Theadditionally achieved range
display edunder Bonus fr.start Bonus
fr.start does
not indicate afixed consumpt ionreduction .
In addition todriving style,theactual con-
sumption isaffect edbyother factors,such as:
R load
R tire pressure
R cold start
R choice ofroute
R active electric alconsumer s
These factorsarenot included inthe ECO dis-
play.
An econom icaldriving stylespecially requires
driving atmoderate enginespeeds.
Achievin gahigher value inthe categories
"Accelerat ion"and"Constant ":
R observe thegearshift recommendations .
R drive thevehicle indrive program Cor E.
In urban trafficand stop- start traffic,drive pro-
gram Cis recomm ended.
On long journeys atac onst antspeed, e.g.on
the highway, onlytheouter areafor"const ant"
will change.
The ECO display summarizes thedriving style
from thestart ofthe journey toits completion .
Therefore, therearemore marked changes in
the outer areas atthe start ofajourney. On
longer journeys, therearefewer changes. For
more marked changes, performamanual rest
