Protection of the environment
General notes
HEnvironmental note
Daimler's declared policy is one of
comprehensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and inamanner
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
environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
Roperating conditionsofyour 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
consumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer need
them.
Raregularly 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
startingthe engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintainasafe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up toof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep an eye on the vehicle's fuel
consumption.
Environmental concerns and
recommendations
Wherever the operating instructions require
you to dispose of materials, first try to
regenerate or re-use them. Observe the
relevant environmental rules and regulations
when disposing of materials. In this way you
will help to protect the environment.
Product information
Mercedes-Benz recommends that you use
genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for your vehicle.
Mercedes-Benz tests genuine parts as well as
conversion parts and accessories that have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Therefore,
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz
vehicles. This is also the case, even if they
have been independently or officially
approved. The use of non-approved parts
could affect your vehicle's operating safety.
Genuine Mercedes-Benz parts, approved
conversion parts and accessories are
available from any authorized Mercedes-Benz
Center. Here, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed.

Pulling away
Automatic transmission
GWARNING
If the engine speed is above the idling speed
and you engage transmission positionDor
R,the vehicle could pull away suddenly. There
isarisk of an accident.
When engaging transmission positionDorR,
always firmly depress the brake pedal and do
not simultaneously accelerate.
!Ifawarning tone sounds and the
Release Park. Brakemessage appears
in the multifunction display,the parking
brake is still applied. Release the parking
brake.
XDepress the brake pedal and keep it
depressed.
XShift the transmission to positionDorR.
XRelease the parking brake (Ypage 169).
XRelease the brake pedal.
XCarefullydepress the accelerator pedal.
iIt is only possible to shift the transmission
from positionPto the desired position if
you depress the brake pedal. Only then is
the parking lock released. If you do not
depress the brake pedal, you can move the
DIRECT SELECT lever but the parking lock
remains engaged.
iThe vehicle locks centrally once you have
pulledaway.The locking knobs in the doors
drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic
locking feature (Ypage 232).
iUpshifts take place at higher engine
speeds afteracold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill startassist
GWARNING
Afterashort time, hill start assist will no
longer brake your vehicle and it could roll
away. There isarisk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle forashort time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
XTake your foot off the brake pedal.
The vehicle is then held for aboutasecond.
XPull away.
Hill start assist will not function if:
Ryou are pulling away onalevel road or on
adownhill gradient.
Rthe transmission is in positionN.
Rthe parking brake is applied.
RESP®is malfunctioning.
ECO start/stop function
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is
stopped under certain conditions.
The engine startsautomatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
reduce the fuel consumption and emissions
of your vehicle.

distracted from traffic conditions. You could
also lose control of the vehicle. There isarisk
of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the
country in which you are driving.Some
jurisdictionsprohibit the driver from using a
mobile phone while drivingavehicle.
If you makeacall while driving,alwaysuse
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over toasafe location and stop
before operatingthe telephone.
Bear in mind that ataspeed of only 30 mph
(approximately 50 km/h) the vehicle covers
adistanceof44ft(approximately 14 m) per
second.
Drive sensibly–save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the
recommended tire pressure.
XRemove unnecessary loads.
XRemove roof racks whenthey are not
needed.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenancework carried out as
indicated by the service intervals in the
MaintenanceBooklet or by the service
interval display.
Fuel consumption also increases when
driving in cold weather, in stop-start traffic
and in hilly terrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Evenasmall amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility ofaserious or even fatal
accident are 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
taking drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
isarisk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, only have work on the engine carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benzservice requirements. Details
can be found in the Maintenance Booklet.

drivingstyle in termsofconsumption,taking
the actual and selected conditionsinto
consideration.Your driving style can
significantly influence the vehicle's
consumption.
The ECO display consistsofthree bars:
RAcceleration
RConstant
RCoasting
The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%.Ahigher
percentage indicatesamoreeconomical
driving style.
The ECO display doesnot indicate the actual
fuelconsumption andafixedpercentage
count in the ECO display doesnot indicate a
fixedconsumption figure.
Apart from driving style, consumption is
dependent on many factors such as,e.g.:
Rload
Rcheck
Rcoldstart
Rchoice of route
Relectrical consumers switched on
These factors are not taken into
consideration by the ECO display.
The evaluation of your driving styleiscarried
outusing the following three categories:
RAcceleration(evaluation of all
acceleration processes):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(assessment of driving behavior
at all times):
-The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
-The bar empties: fluctuations in speed
RCoasting(assessment of all deceleration
processes):
-The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
-The bar empties: frequent braking
iAn economical driving style specially
requires driving at moderate engine
speeds.
To achieveahigher value in the categories
AccelerationandConstant:
Robserve the gearshift recommendations.
Rdrive in drive programE.
iOn long journeys ataconstant speed, e.g.
on the highway, only the bar forConstant
will change.
iThe ECO displaysummaries the driving
characteristics from the start of the journey
to its completion. For this reason, the bars
change dynamically at the beginning of the
journey. On longer journeys, there are
fewer changes. For more dynamic changes,
carry outamanual reset.

Important safety notes
GWARNING
When thevehicle is beinglowered, people
could become trapped if their limbs are
between thevehicle body and thewheelsor
underneaththevehicle.There isarisk of
injury.
Make sure no one is underneath the vehicle
or in the immediate vicinity of the wheel
arches when the vehicle is being lowered.
GWARNING
Vehicles with level control:
The vehicle is slightly lowered if:
Ryou have selected comfort suspension
tuning and
Ryou lock the vehicle within approximately
60 seconds of switching off the engine
You and people in the vicinity of the wheel
arch or the underbody may thus become
trapped. There isarisk of injury.
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you lock
the vehicle.
!The vehicle is lowered by about 15 mm if:
Ryou have selected "Comfort tuning"
Ryou switch off the engine and then
Ryou lock the vehicle within approximately
60 seconds
When parking, position your vehicle so that
it does not make contact with the curb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.
If you lock the vehicle within 60 seconds of
switching the engine off, it lowers slightly to
the selected Comfort suspension mode.
Your vehicle regulates its height
automatically.All-round level control ensures
the best possible suspension and constant
groundclearance, even withaladen vehicle.
When you drive fast,the vehicle is lowered
automatically to improve drivingsafetyand to
reducefuel consumption.
The followingvehicle levels are possible:
Rnormal
Rraised: the vehicle is raised by about
0.80 in (20 mm) when compared with the
normal level
Rlowered: the vehicle is raised by about
0.40 in (10 mm) when compared with the
normal level
iThese changes in level are so slight that
you are hardly aware of them.
The "Normal" and "Raised" vehicle levels can
be set manually.
The "Lowered” vehicle level is set
automatically:
