Operation Manual

The ECO display does not indicate the actual
fuel consumption. A fixed percentage count
in the ECO display does not indicate a fixed
consumption.
Apart from driving style, consumption is
dependent on many factors such as, e.g.:
R
load
R
tire pressure
R
cold start
R
choice of route
R
electrical consumers switched on
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried
out using the following three categories:
R
AccelerationAcceleration (evaluation of all accelera-
tion processes):
-
The bar fills up: moderate acceleration,
especially at higher speeds
-
The bar empties: sporty acceleration
R
ConstantConstant (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
CoastingCoasting (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
To achieve a higher value in the categories
AccelerationAcceleration and ConstantConstant, drive the vehi-
cle in drive program E+ or E.
On long journeys at a constant speed, e.g. on
the highway, only the bar for ConstantConstant will
change.
The ECO display summarizes the driving char-
acteristics 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 a man-
ual reset.
For further information on the ECO display,

WARNING
If you increase the recuperation level on slip-
pery road surfaces, the drive wheels may lose
their traction. There is an increased danger of
skidding and accidents.
Do not increase the recuperation level on slip-
pery road surfaces.
The braking performance of the electric
motor using recuperative braking is, in some
operating modes, either reduced or not effec-
tive:
R
when the condition of charge of the high-
voltage battery increases
R
if the high-voltage battery is not yet at a
normal operating temperature
R
when driving close to the maximum speed
R
when the vehicle is almost stationary
R
in transmission position N
R
during and after ESP stability control
If you do not make an additional effort to
apply the brake yourself, the braking effect
may not be sufficient. If necessary, counter-
act the reduced regenerative braking effect
by applying the brake yourself.
Downhill gradients
On long, steep gradients, you must reduce the
load on the brakes by selecting maximum
recuperation. This helps you to avoid over-
heating the brakes and wearing them out
excessively.
Recuperation allows the vehicle to be decel-
erated without placing a load on the braking
system.
