Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic, on
short journeys and in hilly terrain. 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. Con-
sumption can be significantly influenced by
your driving style.
The ECO display consists of three bars:
R Acceleration
Acceleration
R Constant Constant
R Coasting
Coasting
The percentage count is the mean value of the three bar values. The three bars and the mean
value begin at the value of 50%. A higher per- centage count 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.
In addition to driving style, the consumption is
affected by many 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.
The evaluation of your driving style takes the following three categories into consideration: 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 behav-
iour 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, keep-
ing your distance and early release of the
accelerator. The vehicle can coast with-
out use of the brakes.
- the bar empties: frequent braking
An economical driving style involves driving at a moderate engine speed.
To achieve a higher value in the categories
Acceleration Acceleration andConstant
Constant :
R observe the gearshift recommendation
R drive the vehicle in drive program E(vehi-
cles with automatic transmission)
On long journeys at a constant speed, e.g. on the motorway, only the bar for Constant
Constantwill
change.
The ECO display summarises the driving char-
acteristics from the start of the journey to its completion. Therefore, there are dynamic
changes in the bars at the start of a journey.
During a prolonged driving time, these
changes are smaller. For more dynamic
changes, perform a manual reset.

General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or
increasing lapses in concentration on the part of the driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentra-
tion until too late, or may not detect them at
all. The system is not a substitute for a well-
rested and attentive driver. The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
R if the length of the journey is less than
approximately 30 minutes
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con- tinue your journey if:
R you switch off the engine
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break
