Fuel is highly flammable. If you handle fuel
incorrectly, there is arisk of fire and explo-

You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine

more effor ttosteer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. ECO display
The ECO display provides feedback on how
economical your driving characteristic sare.
The ECO display assists you in achievin gthe
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%. Ahigher per-
centage count indicates amore economical
driving style.
The ECO display does not indicat ethe actual
fuel consumption .Afixed percentage count
in the ECO display does not indicat eafixed
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 choic eofroute
R the use of electrical consumers
These factors are not included in the ECO dis-
play. The evaluation of your driving style take
sthe
following three categories int oconsideration:
R Acceleration Acceleration (evaluation of all accelera-
tion processes):
- the bar fills up: moderat eacceleration,
especially at higher speeds
- the bar empties: sport yacceleration
R Constant
Constant (assessmen tofdriving behav-
iour at all times):
- the bar fills up: constan tspeed and
avoidance of unnecessary acceleration
and deceleration
- the bar empties: fluctuations in speed
R Coasting Coasting (assessmen tofall deceleration
processes):
- the bar fills up: anticipatory driving ,keep-
ing your distanc eand early release of the
accelerator. The vehicle can coast with-
out use of the brakes.
- the bar empties: frequent braking
i An economical driving style involves driv-
ing at amoderat eengin espeed.
To achieve ahigher 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)
i On long journeys at
aconstan tspeed, e.g.
on the motorway, only the bar for Constant
Constant
will change.
i The ECO display summarises the driving
characteristic sfrom the start of the journey
to its completion. Therefore, ther eare
dynamic changes in the bars at the start of aj ourney. Durin gaprolonge ddriving time,
these changes are smaller. For more
dynamic changes, perfor mamanual reset.
