Refueling
Important safety notes
G WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is ar isk 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.
G WARNING
Fuel is poisonous and hazardous to health.
There is ar isk 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: R
Wash away fuel from skin immediately
using soap and water. R
If fuel comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical assistance with-
out delay. R
If fuel is swallowed, seek medical assis-
tance without delay .Don ot induce vomit-
ing. R
Immediately change out of clothing which
has come into contact with fuel.
G WARNING
Electrostatic buildu pc an create sparks and
ignite fuel vapors. There is ar isk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildu pi s
thereby discharged.
Do not get into the vehicle again during the refu-
eling process. Otherwise, electrostatic charge
could build up again.
! Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify aq ualified specialist workshop
and have the fuel tank and fuel lines drained
completely. Refueling 129

Drive sensibly –s ave fuelObserve the following tips to save fuel: R
The tires should always be inflated to the rec-
ommended tire pressure. R
Remove unnecessary loads. R
Warm up the engin eatl ow engin es peeds.R
Avoid frequen ta cceleration or braking.R
Observe the servic ei ntervals in the Mainte-
nanc eB ooklet or in the servic ei nterval dis- play. Have all the maintenanc ew ork 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
G WARNING
Drinkin ga nd driving and/or takin gd rugs and
driving are very dangerous combinations.
Even as mall amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of as erious 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
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Therefor en ever leave
the engin er unning in enclosed spaces with-
out sufficien tv entilation.
Certain engin es ystems are designed to keep
the level of poisonous component sine xhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .A lways have
work on the engin ec arried out at aq ualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Ben zC enter for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at aq ualified specialist
workshop.
The engin es ettings must not be changed under
any circumstances. Furthermore, all specific
servic ew ork must be carried out at regular
intervals and in accordance with the Mercedes-
Ben zs ervic er equirements. Details can be found
in the Maintenance Booklet.134
Driving tips
Driving and parking

In addition to driving style, the actual consump-
tion is affected by other factors, such as: R
load R
tire pressure R
cold start R
choice of route R
active electrical consumers
These factors are not include dint he ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving ah igher valu eint he categories
"Acceleration" and "Constant": R
observe the gearshift recommendations. R
drive the vehicle in drive program C or E .
In urba nt raffic and stop-start traffic, drive pro-
gram C is recommended.
On long journeys at ac onstant 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 satt he start of aj ourney. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform am anua lr est

Braking
Important safety notes
G WARNING
If you shift down on as lippery road surface in
an attempt to increase the engine's braking
effect, the drive wheel sc ould lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on as lippery road surface.
Downhill gradients
! On long, steep gradients, you must reduce
the load on the brakes. To use engine braking,
shift to al owe rg 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 ad rive 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 al owe rg 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 Pilo tD ISTRONIC.
Heavy and light loads
G WARNING
If you rest you rf oot on the brake peda lw 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 peda lasaf ootrest. Never
depres st he brake peda la nd the accelerator
peda latt he same time.
! Depressing the brake peda lc onstantly
results in excessive and premature wea rt o
the brake pads.
If the brakes have been subjected to ah eavy
load ,don ot stop the vehicle immediately ,b ut
drive on for as hort while. This allows the airflow
to cool the brakes more quickly.
Wet roads If you have driven for al ong time in heavy rain
withou tb raking, there may be ad elayed 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 depres st he brake peda lm ore
firmly .M aintai nag reater distance from the
vehicle in front.
After driving on aw et road or having the vehicle
washed, brake firmly whil ep aying attention to
the traffic conditions. This wil lw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.136

Adaptive damping system
General notes
i Mercedes-AMG SLC 43: the adaptive
damping system is called AMG RIDE CON-
TROL sports suspension.
As uspension with the adaptive damping system
provides improved driving comfort and contin-
uously controls the calibration of the dampers.
The damping characteristic sa dapt to the cur-
rent operating and driving situation.
The damping is tuned individually to each wheel
and depends on: R
your driving style, e.g. sporty R
the road surface conditions R
the selected drive program ( Y
page 121).
Selecting the Comfort or Economy drive
programs In the Comfort and Economy drive programs,
the driving characteristic sofy our vehicle are
more comfortable. Select one of these drive
programs if you favor am ore comfortable driv-
ing style. Also select these drive programs when
driving fast on straight roads, e.g. on straight
stretches of highway.
In urban traffic and stop-start traffic, drive pro-
gram C is recommended. X
Press DYNAMIC SELECT button C repeat-
edly until the Comfort or Economy drive pro-
gram is selected.
Selecting Sport mode The firmer setting of the suspension tunin gi n
the Sport drive program ensures even better
contact with the road. Select this drive program
when employing as porty driving style, e.g. on
winding country roads. X
Press DYNAMIC SELECT button C as many
times as necessary until the Sport drive pro-
gram is selected.
Selecting Sport Plus mode The firmer suspension settings in the Sport
