2017 MERCEDES-BENZ SLC engine

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 .
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
Driving tips

importan tift he vehicle is laden. By doing so, you
will make use of the braking effect of the engine.
This relieves the load on the brak es ystem and
prevent st he brakes fro mo verheatin ga nd wear-
ing too quickly.
If Distanc eP ilot DISTRONIC detect st hat there is

Adaptive Damping System
General notes
i Mercedes-Benz SLC 43 AMG: the adap-
tive adjustable damping is called AMG sports
suspension.
As uspension with the Adaptive Damping Sys-
tem provides improved driving comfort and con-
tinuously controls the calibration of the damp-
ers. The damping characteristic sa dapt to the
curren to perating 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. 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
Plus drive program ensures even better contact
with the road. Select this mode when employing
as porty driving style, e.g. on winding country
roads or, ideally ,w hen driving on closed race
circuits. X
Press DYNAMIC SELECT button C repeat-
