Refueling
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is arisk 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 arisk 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.Don ot induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildupc an create sparks and
ignite fuel vapors. There is arisk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildupi s

Drive sensibly –save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to the rec-
ommended tire pressure.
RRemove unnecessary loads.
RWarm up the engin eatlow engin espeeds.
RAvoid frequenta cceleration or braking.
RObserve the servicei ntervals in the Mainte-
nanc eBooklet or in the servicei nterval dis-play. Have all the maintenanc
ework carried in
accordance with Daimler AG regulations.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinkin gand driving and/or takin gdrugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of aserious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Thereforen ever leave
the engin erunning in enclosed spaces with-
out sufficientv entilation.
Certain engin esystems are designed to keep
the level of poisonous component sinexhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .Always have
work on the engin ecarried out at aqualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
BenzC enter for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at aqualified specialist
workshop.
The engin esettings must not be changed under
any circumstances. Furthermore, all specific
servicew ork must be carried out at regular
intervals and in accordance with the Mercedes-
Benzs ervicer equirements. Details can be found
in the Maintenance Booklet.

Rchoice of route
Ractive electrical consumers
These factors are not includedint he ECO dis-

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

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, 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.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,b ut
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
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 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 whilep aying attention to
the traffic conditions. This willw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
136Driving tips
Driving and parking

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

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 brakef luid level may be to olow due to
brak epad wear or leaking brak elines.
Hav ethe brakes ystem 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 (th eSmartKey must be in position uor
1 in th eignitio nlock), if th eelectric parking
brakeist ested onabraking dynamometer
(maximum 10 seconds).
Brakin gtriggered automatically by ESP
®may
cause severe damage to th ebrakes ystem.
All check sand maintenanc ework on th ebrake

and operatin gconditions.
For this reason, it is impossibletos tate am ile-

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
