Protecting the environment
General notes
HEnvironmental 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 amanner
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:
Roperating conditionsofy our vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel con-
sumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer need
them.
Rar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal when
startin gthe engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain asafe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up to Ôof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep an eye on the vehicle's fuel consump-
tion.
Environmental concerns and recom-
mendations
Wherever the Operator's Manual requires you to
dispose of materials, first try to regenerate or re-
use them. Observe the relevant environmental
rules and regulations when disposing of materi-
als. In this way you will help to protect the envi-
ronment.
Genuine Mercedes-Benz parts
HEnvironmental note
Daimler AG also suppliesr econditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new

possible.
ABS (Anti-lock Brakin gSystem)
General information
ABS regulate sbrake pressure in such awaythat
the wheels do not lock when yo ubrake. This
allows yo utocontinue steering the vehicl ewhen
braking. The
! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goe soutwhen the engine is running.
ABS works from aspeed of about5m ph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, eve nwheny ou
onlyb rake gently.
Important safety notes
iObserve the "Important safety notes "sec-
tio n(Ypage 61).
GWARNING
If ABS is faulty ,the wheels could lock when
braking .The steerability and braking charac-
teristic smaybe severely impaired.A ddition-
ally ,further driving safety systemsa re deac-
tivated.T here is an increased danger of skid-
ding and accidents.
Driv eonc arefully. Hav eABS checked imme-
diately at aquali fied specialist workshop.
Whe nABS is malfunctioning ,othe rsystems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 220 )and dis-
play messages which maybes hown in the
instrument cluster (
Ypage 192).
Braking
XIf ABS intervenes: continue to depress the
brake peda lvigorously unti lthe braking sit-

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.
RRemove roof racksw hen they are not needed.
RWarm up the engineatlow engin espeeds.
RAvoid frequenta cceleration or braking.
RHave all maintenanc ework carried out as
indicated by the servicei ntervals in the Main- tenance Booklet or by the servicei
nterval dis-
play.
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.
144Driving tips
Driving and parking

In addition to driving style, the actual consump-
tion is affected by other factors, such as:
RLoad
RTire pressure
RCold start
RChoice of route
RActive electrical consumers
These factors are not includedint he ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving ahigher valu einthe categories
"Acceleration" and "Constant":
Robserve the gearshift recommendations.
Rdrive the vehicle in drive program Cor E
(vehicles with aDYNAMIC SELECT button).
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
the outer areasatt he start ofajourney. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform amanua lrest
(
Ypage 181).
For more information on the ECO display, see
(
Ypage 180).
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 and steep gradients, you must
reduce the load on the brakes by shifting to a
lowerg ear in good time. This allows you to
take advantage of engine braking. For this you
must first activate manua lgearshifting. This helps you to avoid overheating the brakes and
wearing them out excessively.
When you take advantage of engine braking, it
is possible that
adrive wheel willn ot rotate for
some time, e.g. on aslippery road surface.
This could cause damage to the drive train.
This type of damage is not covered by the
Mercedes-Benz warranty.
Briefly depressing the accelerator pedalo n
downhill gradients whilet he manualdrive pro-
gram Mis temporarilya ctivated: the automatic
transmission may switch to the last active auto-
matic drive program Eor S.T he automatic trans-
missionm ay shift to ahigherg ear. This can
reduce the engine's braking effect.
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.D rive
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 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.
