for example, the power steering and the brake
boosting effect. You wil lr equire considerably
more effort to steer and brake. There is ar isk
of an accident.
Do not switch off the ignition while driving.
G WARNING
If you operate mobile communication equip-
ment while driving, you wil lbed istracted from
traffic conditions. You coul da ls ol ose control
of the vehicle. There is ar isk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the lega lr equirements for the country
in which you are driving. Some jurisdictions pro-
hibi tt he drive rf rom using am obile phone while
driving av ehicle.
If you make ac all while driving, alway su se
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pul lo ver to as afe location and stop
before operating the telephone.
Bear in mind that at as pee dofo nly 30 mph
(approximately 50 km/h) ,t he vehicl ec overs a
distance of 44 ft (approximately 14 m) per sec-
ond.
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. Work relevant to
safety or work on safety-related systems in par-
ticular must be carried out at aq ualified spe-
cialist 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 Maintenanc eB ooklet.
ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you
in achievin gt he most economical driving style
for the selected settings and prevailing condi-
tions. Your driving style can significantly influ-
enc et he vehicle's consumption.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 .
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
Driving and parking

Limited braking performance on salt-
treated roads If you driv eons alted roads ,al ayer of salt resi-
due may for mont he brak ed isc sa nd brake
pads. This can result in as ignificantly longer
braking distance. R
In orde rtop revent any salt build-up, apply the
brakes occasionally while paying attention to
th et ra ffic conditions.R
Carefully depress th eb rak ep edal and the
beginnin ga nd end of aj ou rney.R

Use cruise control only if road and traffic con-
dition sm ake it appropriate to maintain as teady
speed for ap rolonged period. You can stor ea ny
road speed above 20 mph (30 km/h).
Important safet yn otesIf 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 int oa ccoun tt 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 gi n
good time and for staying in lane.
Do not use cruise control: R
in road and traffic condition sw hich do not
allow you to maintain ac onstan ts peed e.g. in

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
