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 a manner
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 affec-
ted by these factors:
Roperating conditions of your 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.
Ra regularly 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 starting the engine.
Rdo not warm up the engine when the vehi-
cle is stationary.
Rdrive carefully and maintain a safe dis-
tance from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each
gear only up to

ECO start/stop function
Introduction
The ECO start/stop function switches theengine off automatically if the vehicle is stop-ped under certain conditions.
The engine starts automatically when thedriver wants to pull away again. The ECOstart/stop function thereby helps you toreduce the fuel consumption and emissions ofyour vehicle.
Important safety notes
GWARNING
If the engine is switched off automatically
and you exit the vehicle, the engine is
restarted automatically. The vehicle may
begin moving. There is a risk of accident and
injury.
If you wish to exit the vehicle, always turn
off the ignition and secure the vehicle
against rolling away.
General notes
CECO start/stop display
The ECO start/stop function is activatedwhenever you start the engine using theSmartKey or the Start/Stop button.
If the engine has been switched off automati-cally by the ECO start/stop function, the

Holding the vehicle stationary on
uphill gradients
GWARNING
If the clutch overheats, the electronic man-
agement system is automatically deactiva-
ted. This interrupts the power transmission.
The vehicle may, for example, roll back-
wards on gradients. There is a risk of an
accident.
Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
The clutch may overheat if you hold the vehi-cle stationary on uphill gradients by depress-ing the accelerator pedal. If the clutch over-heats, a warning tone sounds.

XEase off the accelerator pedal once thedesired speed is reached.The automatic transmission shifts back up.
Mercedes-AMG vehicles:it is only possibleto use kickdown in the automatic drive pro-gram and the temporary manual drive programM. When manual drive programMis perma-nently activated, kickdown is not possible.
For further information on kickdown in manualdrive programM(Ypage 142).
Rocking the vehicle free
Shifting back and forth between transmissionpositions[and^can help to free up thevehicle if it gets stuck in mud or snow. Thevehicle's engine management system limitsthe speed to a maximum of 5 mph (9 km/h)when shifting back and forth. To shift repeat-edly between transmission positions[and^, move the DIRECT SELECT lever up anddown past the point of resistance.

RThe tires should always be inflated to therecommended tire pressure.
RRemove unnecessary loads.
RRemove roof racks when they are not nee-ded.
RWarm up the engine at low engine speeds.
RAvoid frequent acceleration or braking.
RHave all maintenance work carried out asindicated by the service intervals in theMaintenance Booklet or by the service inter-val display.
Fuel consumption also increases when drivingin cold weather, in stop-start traffic and in hillyterrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident 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
taking drugs.
Emission control
GDANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
Certain engine systems are designed to keepthe level of poisonous components in exhaustfumes within legal limits.
These systems only work at peak efficiency ifthey are serviced exactly in accordance withthe manufacturer's specifications. Always havework on the engine carried out at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose. In particular,work relevant to safety or on safety-relatedsystems must be carried out at a qualified spe-cialist workshop.
The engine settings must not be changedunder any circumstances. Furthermore, allspecific service work must be carried out atregular intervals and in accordance with theMercedes-Benz service requirements. Detailscan be found in the Maintenance Booklet.

Underinflated tires may:
Roverheat, leading to tire defects
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on fuel consumption
Overinflated tires
GWARNING
Tires with excessively high pressure can
burst because they are damaged more eas-
ily by road debris, potholes etc. In addition,
they also suffer from irregular wear, which
can severely impair the braking properties
and the driving characteristics. There is a
risk of an accident.
Avoid tire pressures that are too high in all
the tires, including the spare wheel.
Overinflated tires may:
Rincrease the braking distance
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on ride comfort
Rbe more susceptible to damage
Maximum tire pressures
CExample: maximum permissible tire pres-sure
Never exceed the maximum permissible tireinflation pressure. Always observe the recom-mended tire pressure for your vehicle whenadjusting the tire pressure (Ypage 307).
iThe actual values for tires are vehicle-spe-cific and may deviate from the values in theillustration.
Checking the tire pressures
Important safety notes
The tire pressure monitor does not warn youof:
Rincorrectly set tire pressure
Rsudden loss of tire pressure, e.g. from a for-eign object that has penetrated the tire
Observe the notes on tire pressure(Ypage 307).
Information on air pressure for the tires onyour vehicle can be found:
Ron the vehicle's Tire and Loading Informa-tion placard on the B-pillar
Rin the tire pressure table in the fuel filler flap(Ypage 144)
Rin the "Tire pressure" section
Checking tire pressures manually
To determine and set the correct tire pressure,proceed as follows:
XRemove the valve cap of the tire that is tobe checked.
XPress the tire pressure gauge securely ontothe valve.
XRead the tire pressure and compare it to therecommended value on the Tire and LoadingInformation placard or the tire pressuretable (Ypage 307).
XIf the tire pressure is too low, increase thetire pressure to the recommended value.
XIf the tire pressure is too high, release air.To do so, press down the metal pin in thevalve, using the tip of a pen for example.Then check the tire pressure again using thetire pressure checker.
XScrew the valve cap onto the valve.
XRepeat these steps for the other tires.

which have been approved by Mercedes-Benz specifically for your vehicle.
These tires have been specially adapted foruse with the control systems, such as ABS
or ESP®, and are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended(tires featuring run-flat characteristics)
RMO1 = Mercedes-Benz Original (only cer-tain AMG tires)
Mercedes-Benz Original Extended tires mayonly be used on wheels that have been spe-cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories testedand approved by Mercedes-Benz. Certaincharacteristics, e.g. handling, vehicle noiseemissions or fuel consumption, may other-wise be adversely affected. In addition,when driving with a load, tire dimension var-iations could cause the tires to come intocontact with the bodywork and axle compo-nents. This could result in damage to thetires or the vehicle.
Mercedes-Benz accepts no liability for dam-age resulting from the use of tires, wheelsor accessories other than those tested andapproved.
Information on tires, wheels and approvedcombinations can be obtained from anyqualified specialist workshop.
!Retreaded tires are neither tested nor rec-ommended by Mercedes-Benz, since previ-ous damage cannot always be detected onretreaded tires. As a result, Mercedes-Benzcannot guarantee vehicle safety if retreadedtires are mounted. Do not mount used tiresif you have no information about their previ-ous usage.
The recommended pressures for various oper-ating conditions can be found:
Ron the Tire and Loading Information placardon the B-pillar on the driver's side
Rin the tire pressure table in the fuel filler flap
Observe the notes on recommended tire pres-sures under various operating conditions(Ypage 307).
Check tire pressures regularly, and only whenthe tires are cold. Comply with the mainte-nance recommendations of the tire manufac-turer in the vehicle document wallet.
Notes on the vehicle equipment – alwaysequip the vehicle:
Rwith tires of the same size on a given axle(left and right)
Rwith the same type of tire (summer tires,MOExtended tires, winter tires)
Exception: it is permissible to install a differ-ent type or make in the event of a flat tire.Observe the "MOExtended tires (tires withrun-flat characteristics" section(Ypage 288).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory.It is therefore recommended that you addition-ally equip your vehicle with a TIREFIT kit if youmount tires that do not feature run-flat proper-ties, e.g. winter tires. A TIREFIT kit may beobtained from a qualified specialist workshop.
Emergency spare wheel
Important safety notes
GWARNING
The wheel or tire size as well as the tire type
of the spare wheel or emergency spare
wheel and the wheel to be replaced may dif-
fer. Mounting an emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of an accident.
To avoid hazardous situations:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel
or emergency spare wheel that differs in
size.
Ronly use a spare wheel or emergency
spare wheel of a different size briefly.
Rdo not switch ESP®off.
Rhave a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimen-
sions as well as the tire type must be cor-
rect.
