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.

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

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.

Driving and parking

Limited braking performance on salt-
treated roads
If you driveonsalted roads,alayer of salt resi-
due may for monthebrak ediscsa nd 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

Servicing th ebrakes
!The brakef luid level may be to olow, if:
Rif th ered brakew arning lamp lightsupi n
th ei nstrumentc luster and
Ryou hearawarning tone while th eengine is
running
Observe additional warning messages in the
multifunction display.
The brak efluid level may be to olow due to
brak epad wear or leaking brakel ines.
Hav ethe brak esystem checked immediately.
Consult aqualifie dspecialist workshop to
arrange this.
!As th eESP®system operates automatically,
th ee ngine and th eignitio nmust be switched
off (SmartKey in position 0or 1in th eignition
lock) if th eelectric parking brakeisb eingtes-
ted on abraked ynamometer (maximum
10 seconds).

If th ebrakes ystem has onl ybeen subject to

ity of your brakes at regular intervals.

High-performance brake system
(Mercedes-Benz SLC 43 AMG)
AM Gb rakes ystems are designed for heavy
loads and have component swith corresponding
properties. This may lead to noise when braking.
This will dependo n:
RSpeed
RBrakingforce
RAmbientc onditions, e.g .temperature and

The wear of individual component softhebrake
system, such as th ebrakep ads/linings or brake
discs, depends on th eindividual driving style
and operatin gconditions.
For this reason, it is impossibletos tate am ile-
age that will be valid unde rall circumstances. An
aggressived riving style will lead to high wear.
You can obtain morei nformationonthisf roma

New and replaced brak epads and discso nly
reacht heir optimum braking effect after several
hundred kilometers of driving .Compensate for
this by applyingg reater force to thebrakep edal.
Keep this in mind, and adapt your driving and
braking accordingl yduringt hisb reak-in period.
Excessive heavy braking results in correspond-
ingly high brak ewear. Observe th ebrakes ystem

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

XRemove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.
You can stor ethe currents peed if you are driv-
ing faster than 20 mph (30 km/h).
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.
Storing or calling up aspeed
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
brake unexpectedly. There is arisk of an acci-
dent.
Pay attention to the road and traffic condi-
tion sbefore calling up the stored speed. If you
do not know the stored speed, stor ethe

XRemove your foot from the accelerator pedal.
The first time cruise control is activated, it
stores the currents peed or regulates the

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.
