Protecting the environment
General notes
H Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in am anner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors: R
operating condition sofy our vehicleR
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions: R
avoid short trips as these increase fuel con-
sumption. R
always make sure that the tire pressures
are correct. R
do not carry any unnecessary weight. R
remove roof racks once you no longer need
them. R
ar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals. R
always have service work carried out at a
qualified specialist workshop.
Personal driving style: R
do not depress the accelerator pedal when
startin gt he engine.R
do not warm up the engine when the vehicle
is stationary. R
drive carefully and maintain as afe distance
from the vehicle in front. R
avoid frequent, sudden acceleration and
braking. R
change gear in good time and use each gear
only up to

Do no ts witch of ft he ignition whil ed riving.
G WARNING
If you operat em ob ile communication equip -
men tw hen driving, you may be distracted
from th et ra ffic situation .Y ou could also los e

Only operat et hi se quipmen tw hen th ev ehicle

Observ et he lega lr equirements fo rt he country
in whic hy ou are driving. Some jurisdiction sp ro -
hibi tt he driver from usin gam ob ile phone whil e
drivin gav ehicle.
If you mak eac al lw hil ed riving, always use
hands-free mode. Only operat et he telephon e
when th et ra ffic situation permits. If you are
unsure ,p ull over to as af el ocation and stop
befor eo peratin gt he telephone.
Bear in min dt ha tatas peed of only 30 mph
(approximately 50 km/h), th ev ehicle cover sa
distanc eo f4 4f t( 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. 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
( Y
page 167).
Further information on the ECO display

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

Parking tips: R
on narrow roads, drive as closely as possible
past the parking space R
parking spaces that are littered or overgrown
might be identified or measured incorrectly R
parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly R
snowfall or heavy rain may lead to ap arking
space being measured inaccurately R
pay attention to the Active Parking Assist
PARKTRONIC warning messages during the
parking procedure ( Y
page 151)R
when transportin gal oad which protrudes
from your vehicle, you should not use Parking
Guidance R
never use Parking Guidance with snow chains
or an emergenc ys pare wheel fittedR
make sure that the tire pressures are always
correct. This has ad irect effect on the steer-
ing instructions R
the way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in fron ta nd
behind it and the conditions of the location. In
some cases, Parking Guidance may guide you
too far or not far enough into ap arking space.
In some cases, it may also lead you across or
ont ot he curb. If necessary, cancel the park-
ing procedure with Parking Guidance.
