The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%. A higher percentage
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 consump-
tion.
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
Active electrical consumers
R
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried out
using the following three categories:
Accel. (evaluation of all acceleration pro-
R
cesses)
The bar fills up: moderate acceleration,
-
especially at higher speeds
The bar empties: sporty acceleration
-
Constant (assessment of driving behavior at
R
all times)
The bar fills up: constant speed and avoid-
-
ance of unnecessary acceleration and
deceleration
The bar empties: fluctuations in speed
-
Coasting (assessment of all deceleration
R
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
-
An economical driving style specially requires
driving at moderate engine speeds.

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.
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. Drive
page 190).
