Operation Manual

The evaluation of your driving style is carried out
using the following three categories:
R
Acceleration (evaluation of all acceleration
processes):
-
The bar fills up: moderate acceleration,
especially at higher speeds
-
The bar empties: sporty acceleration
R
Constant (assessment of driving behavior at
all times):
-
The bar fills up: constant speed and avoid-
ance of unnecessary acceleration and
deceleration
-
The bar empties: fluctuations in speed
R
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 without
use of the brakes.
-
The bar empties: frequent braking
i
An economical driving style specially
requires driving at moderate engine speeds.
To achieve a higher value in the categories
Acceleration
and Constant:
R
observe the gearshift recommendations.
R
drive in drive program E.
i
On long journeys at a constant speed, e.g.
on the highway, only the bar for Constant
will
change.
i
The ECO display summarizes the driving
characteristics from the start of the journey to
its completion. For this reason, the bars
change dynamically at the beginning of the
journey. On longer journeys, there are fewer
changes. For more dynamic changes, carry
out a manual reset.
For further information on the ECO display, see

Y page 199).
Braking
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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing 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.
This helps you to avoid overheating the
brakes and wearing them out excessively.
When you take advantage of engine braking, 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 war-
ranty.
Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. causing the
brakes to rub by constantly applying light pres-
sure to the pedal. This results in excessive and
premature wear to the brake pads.
Change into a lower gear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden.
Heavy and light loads
G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!
Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the airflow
to cool the brakes more quickly.
