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
Accel. (evaluation of all acceleration pro-
cesses):
-
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 a higher value in the categories
Acceleration and Constant :
R
observe the gearshift recommendations.
R
drive in drive program E.
i
On long journeys at a constant speed, e.g.
on the highway, only the bar for 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
fewer changes. For more dynamic changes,
carry out a manual reset.

Brakes
Important safety notes
G WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
!
On long, steep gradients, you must
reduce the load on the brakes. To use
engine braking, shift to a lower gear in good
time. This helps you to avoid overheating
the brakes and wearing them out exces-
sively.
When making use of the engine braking
effect, it is possible that a drive wheel may
not turn for some time, e.g. in the case of
suddenly changing or slippery road surface
conditions. This could cause damage to the
drive train. This type of damage is not cov-
ered by the Mercedes-Benz warranty.
Change into a lower gear in good time on long
and steep downhill gradients. This is espe-
cially important if the vehicle is laden.
This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
