Driving tips

Apart from driving style, consumption is
dependent on many factors such as, e.g.:
load
R
tire pressure
R
cold start
R
choice of route
R
electrical consumers switched on
R
These factors are not taken into
consideration by the ECO display.
The evaluation of your driving style is carried
out using the following three categories:
Acceleration
R
acceleration processes):
The bar fills up: moderate acceleration,
-
especially at higher speeds
The bar empties: sporty acceleration
-
Constant (assessment of driving behavior
R
at all times):
The bar fills up: constant speed and
-
avoidance of unnecessary acceleration
and deceleration
The bar empties: fluctuations in speed
-
Coasting (assessment of all deceleration
R
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

An economical driving style specially

The ECO display summaries the driving
characteristics from the start of the journey
to its completion. For this reason, the bars

journey. On longer journeys, there are
fewer changes. For more dynamic changes,
carry out a manual reset.

Important safety notes

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
braking on a slippery road surface.
Downhill gradients
! On long and steep gradients, you must
reduce the load on the brakes by shifting to
a lower gear in good time. This allows you
to take advantage of the engine's braking
effect. For this, you need to have selected
manual drive program M. This helps you to
avoid overheating the brakes and wearing
them out excessively.
When you take advantage of the engine's
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Benz warranty.
i
Briefly depressing the accelerator pedal
on downhill gradients while the manual
drive program M is temporarily activated:
the automatic transmission may switch to
the last active automatic drive program E
or S. The automatic transmission may shift
to a higher gear. This can reduce the
engine's braking effect.
