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 includedint he ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.

Robserve the gearshift recommendations.
Rdrive the vehicle in drive program Cor E
(vehicles with aDYNAMIC SELECT button).
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 areasatt he start ofajourney. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform amanua lrest

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 wheelsc ould 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 and steep gradients, you must
reduce the load on the brakes by shifting to a
lowerg ear in good time. This allows you to
take advantage of engine braking. For this you
must first activate manua lgearshifting. This helps you to avoid overheating the brakes and
wearing them out excessively.
When you take advantage of engine braking, it
is possible that
adrive wheel willn ot rotate for
some time, e.g. on aslippery road surface.
This could cause damage to the drive train.
This type of damage is not covered by the
Mercedes-Benz warranty.
Briefly depressing the accelerator pedalo n
downhill gradients whilet he manualdrive pro-
gram Mis temporarilya ctivated: the automatic
transmission may switch to the last active auto-
matic drive program Eor S.T he automatic trans-
missionm ay shift to ahigherg ear. This can
reduce the engine's braking effect.
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.T here 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 weart o
the brake pads.
If the brakes have been subjected to aheavy
load,don ot stop the vehicle immediately.D rive
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
withoutb raking, 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 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 whilep aying attention to
the traffic conditions. This willw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.

Limited braking performance on salt-
treated roads
If you driveonsalted roads,alayer of salt resi-
due may for monthebraked iscsand brake
pads. This can result in asignificantly longer
braking distance.
RIn ordertop revent any salt build-up, apply the
brakes occasionally while paying attention to th et raffic conditions.
RCarefully depress th ebrakep edal and the
beginnin gand end of ajou rney.
RMaintain agreater distanc etothevehicle

If you leave the engine or the auxiliary heatingrunning, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have you rvehicle winter-proofed at aqualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise control or Distance PilotD ISTRONIC.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
XTry to bring the vehicle under control using
corrective steering.
The outsidet emperature indicator is not
designed to serve as an ice-warning device and is therefore unsuitable for that purpose.
Changes in the outsidet emperature are dis-
played after ashort delay.
Indicated temperature sjust above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
woodeda reasoronb ridges.
You shoul dpay speciala ttention to road condi-
tions when temperature sare around freezing
point.

Cruise control
General notes
Cruise control maintains aconstant road speed
for you .Itbrakes automatically in order to avoid
exceeding the set speed.Onl ong and steep
downhill gradients, especially if the vehicle is
laden, you must select alow gear in good time.
You need to shift manually using the steering
wheel paddle shifters beforehand. By doing so,
you willm ake use of the braking effect of the engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
When the engine is running, you can use the
cruise control lever to limitt
he speed to any
speed between20m ph (30 km/h)and the tech-
nicallyp ermitted maximum speed of the vehicle.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain asteady
speed for aprolongedp eriod.
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes
If you fail to adapt you rdriving style, cruise con-
trol can neither reduce the risk of an accident
nor override the lawsofp hysics. Cruise control
cannot take into account the road, traffic and
weather conditions. Cruise control is only an
aid.Y ou are responsible for the distance to the
vehicle in front, for vehicle speed,f or braking in
good time and for staying in you rlane.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain aconstant speed,e .g. in
heavy traffic or on winding roads
Ron slippery road surfaces .Braking or accel-
erating could cause the drive wheelstol ose
traction and the vehicle could then skid
Rin poor visibility, e.g. due to fog, heavy rain or
snow
If there is achange of drivers, advise the new
driver of the speed stored.

Distance Pilot DISTRONIC
General notes
Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tanc etot he vehicle detected in front. Vehicles
are detected with the aid of the radar sensor
system. Distance Pilot DISTRONIC brakes auto-
matically to avoid exceedingt he set speed or to
maintain the designated distanc efrom the vehi-
cle in front.
If Distance Pilot DISTRONIC detect sthat there is
ar isk of acollision, you will be warned visually
and acoustically. Without your intervention, Dis-
tanc ePilot DISTRONIC cannot prevent acolli-
sion. An intermittent warning ton ewill then
sound and the distanc ewarning lamp will light
up in the instrument cluster. Brake immediately
in order to increase the distanc etothe vehicle in
frontort ake evasive action provided it is safe to
do so.
Distance Pilot DISTRONIC operates in the range
between 0mph (0 km/h) and 120 mph
(200 km/h).
Change into alower gear in good time on long
and steep downhill gradients .This is especially
importan tifthe vehicle is laden. By doing so, you
will make use of the braking effect of the engine.
This relieves the load on the brake system and
preventst he brakes from overheatin gand wear-
ing too quickly.
Do not use Distance Pilot DISTRONIC on roads
with steep gradients.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Sinc eDistance Pilot DISTRONIC transmits radar
waves, it can resemble the radar detectors of
the responsible authorities. You can refer to the
relevant chapter in the Operator' sManual if
questions are asked about this.
