In addition to driving style, the actual consump-
tion is affected by other factors, such as:
Rload
Rtire pressure
Rcold start
Rchoice of route
Ractive electrical consumers
These factors are not include dinthe ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving ahigher valu einthe categories
"Acceleration" and "Constant":
Robserve the gearshift recommendations.
Rdrive the vehicle in drive program Cor E.
On long journeys at aconstant speed,e .g. on the
highway, only the outer area for "constant" will
change.
The ECO display summarizes the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer area satthe start of ajourney. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform amanua lrest
(
Ypage 167).
For more information on the ECO display, see

Braking
Important safety notes
GWARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect, the drive wheel scould lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on aslippery road surface.
Downhill gradients
!On long, steep gradients, you must reduce
the load on the brakes. To use engine braking,
shift to alowerg ear in good time. This helps
you to avoid overheating the brakes and wear-
ing them out excessively. When making use of the engine braking
effect, it is possible that
adrive wheel may not
turn for some time, e.g. in the case of sud-
denly changing or slippery road surface con-
ditions. This could cause damage to the drive
train. This type of damage is not covered by
the Mercedes-Benz warranty.
Change into alowerg ear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden.
This also applies if you have activated cruise
control or Distance PilotD ISTRONIC.
Heavy and light loads
GWARNING
If you rest you rfoot on the brake pedalw hile
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 pedalasaf ootrest. Never
depresst he brake pedala nd the accelerator
pedalatt he same time.
!Depressing the brake pedalc onstantly
results in excessive and premature wea rto
the brake pads.
If the brakes have been subjected to aheavy
load ,don ot stop the vehicle immediately ,but
drive on for ashort while. This allows the airflow
to cool the brakes more quickly.
Wet roads
If you have driven for along time in heavy rain
withou tbraking, there may be adelayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You then have to depresst he brake pedalmore
firmly.M aintainagreater distance from the
vehicle in front.
After driving on awet road or having the vehicle
washed, brake firmly whil epaying attention to
the traffic conditions. This willw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.

overheating and wearing too quickly.
Use cruise control only if road and traffic con-
ditionsmake it appropriate to maintain asteady
speed for aprolonged period. You can stor eany
road speed above 20 mph (30 km/h).
Important safetyn otes
If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take intoaccountt he road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for the distance to the
vehicle in front, for vehicle speed, for brakin gin
good time and for staying in lane.
Do not use cruise control:
Rin road and traffic condition swhich do not
allow you to maintain aconstan tspeed e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces.B raking or accel-
eratin gcould cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen ther eispoor visibility, e.g. due to fog,

iCruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradient sbyauto-
matically applying the brakes.

GWARNING
If you call up the stored speed and it differs
from the currents peed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerateo r

Settingaspeed
GWARNING
Keep in mind that it may take abrief moment
until the vehicle has made the necessary
adjustments.
Increase or decrease the set vehicle speed to
av alue that the prevailing road conditionsa nd
legal speed limits permit. Otherwise, sudden
and unexpected acceleration or deceleration
of the vehicle could cause an accident and/or
serious injury to you and others.
XTo adjust the set speed in 1mph incre-
ments (1 km/h increments): briefly press
the cruise control lever up :to the pressure
point for ahigher speed, or down ?for a
lower speed.
Every time the cruise control lever is pressed
up or down, the last speed stored is increased
or reduced.
XTo adjust the set speed in 5mph incre-
ments (10k m/h increments): briefly press
the cruise control lever up :past the pres-
sure point for ahigher speed, or down ?for
al ower speed.
Ever ytime the cruise control lever is pressed
up or down, the last speed stored is increased
or reduced.
iThe speed indicated in the speedometer
may differ slightly from the speed stored.
iCruise control is not deactivated if you
depress the accelerator pedal. For example, if you accelerateb riefly to overtake, cruise con-
trol adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:
XBriefly press the cruise control lever for-
wards :.

XIf you want to pull away with Distance
Pilot DISTRONIC: remove your foot from the
brake pedal.
XBriefly pull the cruise control lever towards
you ?.
or
XIf Distance Pilot DISTRONIC is activated:
accelerateb riefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on adiffer-
ent line from another vehicle. The vehicle then
brakes automatically. Be ready to brake at all
times.
If ther eisnov ehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise
control.
If Distance Pilot DISTRONIC detects aslower-
movingv ehicle in front, it brakes your vehicle. In
this way, the distanc eyou have selected is main-
tained.
If Distance Pilot DISTRONIC detects afaster-
movingv ehicle in front, it increases the driving
speed. However, the vehicle is only accelerated
up to the speed you have stored.
Selecting the drive program
Distance Pilot DISTRONIC supports asporty
driving style when you have selected the Sor S+
drive program (
Ypage 121). Acceleration
behind the vehicle in frontortothe set speed is
