The ECO display consists of three sections, with
an inner and outer area. The sections corre-
spond to the following three categories: :
Acceleration
(evaluation of all accel-
eration processes):
R the outer area fills up and the inner
area lights up green: moderate
acceleration, especially at higher
speeds
R the outer area empties and the
inner area is grey: sporty acceler-
ation ;
Coasting
(evaluation of all decelera-
tion processes):
R the outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
R the outer area empties and the
inner area is grey: frequent heavy
braking =
Constant
(continuous evaluation
over the entire journey):
R the outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and deceleration
R the outer area empties and the
inner area is grey: fluctuations in
speed The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range
displayed under Bonus fr. start
Bonus fr. start does not
indicate a fixed consumption reduction. In addition to driving style, the actual consump-
tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style involves driving at a moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation
R drive the vehicle in the Comfortdrive pro-
gram.
On long journeys at a constant speed, e.g. on the
motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. During a prolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 245).

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.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by constantly applying light
pressure to the pedal. This results in excessive
and premature wear to the brake pads. Driving tips
