Refueling
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.

RAccel.(evaluation of all acceleration pro-
cesses):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(assessment of driving behavior
at all times):
-The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
-The bar empties: fluctuations in speed
RCoasting(assessment of all deceleration
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
iAn economical driving style specially
requires driving at moderate engine
speeds.
To achieve a higher value in the categories
Acceleration
and Constant:
Robserve the gearshift recommendations.
Rdrive in drive program E.
iOn long journeys at a constant speed, e.g.
on the highway, only the bar for Constant
will change.
iThe 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 more information on the ECO display, see
(
Ypage 226).
Brakes
Important safety notes
GWARNING
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, steep gradients, you must
reduce the load on the brakes. To use
engine braking, shift to a lower gear in good
time. This helps you to avoid overheating
the brakes and wearing them out exces-
sively.
When making use of the engine braking
effect, it is possible that a drive wheel may
not turn for some time, e.g. in the case of
suddenly changing or slippery road surface
conditions. This could cause damage to the
drive train. This type of damage is not cov-
ered by the Mercedes-Benz warranty.
Change into a lower gear in good time on long
and steep downhill gradients. This is espe-
cially important if the vehicle is laden.
This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
Heavy and light loads
GWARNING
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.
