the actual and selected condition sinto
consideration .Your driving style can
significantly influence the vehicle's
consumption.
The ECO display consist softhree bars:
R Acceleration R
Constant R
Coasting The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%. Ahigher
percentage indicates amoree conomical

The ECO display doe snot indicate the actual

Apart from driving style, consumption is
dependent on many factors such as ,e.g.:
R load
R check
R col ds tart
R choice of route
R electrical consumers switched on
These factors are not taken into
consideration by the ECO display.
The evaluation of your driving styl eiscarried
ou tu sing the following three categories: R
Acceleration (evaluation of all
acceleration processes):
- The bar fills up: moderate acceleration,
especially at higher speeds
- The bar empties: sporty acceleration
R Constant (assessment of driving behavior
at all times):
- The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
- The bar empties: fluctuations in speed
R Coasting (assessment of all deceleration
processes):
- The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
- The bar empties: frequent braking
i An economical driving style specially
requires driving at moderate engine
speeds.
To achieve ahigher value in the categories

Constant :
R observe the gearshift recommendations.
R drive in drive program E.
i On long journeys at aconstant speed, e.g.
on the highway, only the bar for Constant will change.
i The ECO displays ummaries the driving
characteristics from the start of the journey
to its completion. For this reason, the bars
change dynamically at the beginning of the
journey. On longer journeys, there are
fewer changes. For more dynamic changes,
carry out amanual reset.
