These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, all work on the engine must be carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benz service requirements. Details
can be found in the Maintenance Booklet.
ECO display
Example: ECO display
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
ted settings and prevailing conditions. Your
driving style can significantly influence the
vehicle's consumption.
The ECO display consists of three bars:
R
Acceleration Acceleration
R
Constant Constant
R
Coasting 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%. A higher percent-
age indicates a more economical driving
style.
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
Acceleration Acceleration (evaluation of all accelera-
tion processes):
-
The bar fills up: moderate acceleration,
especially at higher speeds
-
The bar empties: sporty acceleration
R
Constant 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 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 a higher value in the categories
Acceleration Acceleration and Constant Constant , observe the
gearshift recommendations.
i
On long journeys at a constant speed, e.g.
on the highway, only the bar for Constant Constant
will change.
i
The ECO display summarizes 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
