Mercedes-Benz V-Class Operating Instructions Manual page 195

In addition to driving style, the actual fuel con-
sumption is affected by other factors, such as:
load
R
tyre pressure
R
cold start
R
choice of route
R
the use of electrical consumers
R
These factors are not taken into consideration
by the ECO display.
An economical driving style involves driving at a
moderate engine speed.
You will drive in a fuel-efficient manner and will
obtain better results in the "Acceleration" and
"Constant" categories if you:
observe the gearshift recommendations on
R
vehicles with a manual transmission

( page 174)
on vehicles with an automatic transmission,
R
drive in drive program E (
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. After a
prolonged driving time, these changes are
smaller. To obtain a clearer evaluation of the
current period during the journey, you must
Y
reset the values ( page 250).
If you interrupt your journey and switch off the
ignition for longer than four hours, the values of
the ECO display are reset automatically.
Short journeys
! If the vehicle is predominantly used for
short-distance driving, this could lead to a
fault in the automatic cleaning function for
the diesel particle filter. As a result, fuel may
accumulate in the engine oil and cause engine
failure.
! During automatic regeneration, extremely
hot exhaust gases escape from the exhaust
pipe. Maintain a distance of at least 1 metre to
other objects, e.g. parked vehicles, in order to
avoid damage to property.
If you mainly drive short distances, you should
drive on a motorway or an inter-urban road for

20 minutes every 500 km. This facilitates the
regeneration of the diesel particle filter.
Speed limiter
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There
is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load rating and speed rating required for
your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the maxi-
mum permissible speed based on the tyres (tyre
and tyre pressure). Pay special attention to the
country-specific requirements for tyre approval.
You must not exceed the speed limit for the
tyres specified by the speed rating. The speed
rating is stated in the tyre tables (
You can permanently limit the permissible max-
imum speed of your vehicle, e.g. for driving on
winter tyres.
Mercedes-Benz recommends that you have the
maximum permissible speed programmed at a
Mercedes-Benz Service Centre.
On vehicles with SPEEDTRONIC, you can tem-
porarily or permanently limit the permissible
maximum speed of your vehicle using the on-
Y
board computer ( page 199).
Before overtaking, take into consideration that
the engine speed limiter prevents the speed
increasing beyond the programmed permissible
maximum speed.
On downhill gradients, the speed limitation may
be exceeded. Apply the brakes if necessary.
Display messages indicate that you are
approaching the limit speed.
