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

Rsetting a more favorable seat position forthe front-passenger seat.
Rvehicles with a multicontour seat: increasingthe air pressure in the side bolsters of theseat backrest.
!Make sure that there are no objects in thefootwell or behind the seats. There is a dan-ger that the seats and/or objects could be
damaged when PRE-SAFE®is activated.
Should an accident not occur, the preventativemeasures taken are reversed. Certain settingsmust be made yourself.
XIf the seat belt pre-tensioning is notreduced, move the seat backrest backslightly.Seat belt pre-tensioning is released.
PRE-SAFE®PLUS (anticipatory occu-
pant protection system PLUS)
Introduction
PRE-SAFE®PLUS is only available in vehicleswith the Driving Assistance package.
Using the radar sensor system, PRE-SAFE®
PLUS is able to detect that a head-on or rear-end collision is imminent. In certain hazardous
situations, PRE-SAFE®PLUS takes pre-emptivemeasures to protect the vehicle occupants.
Important safety notes
The intervention of PRE-SAFE®PLUS cannotprevent an imminent collision.
The driver is not warned about the intervention
of PRE-SAFE®PLUS.
PRE-SAFE®PLUS does not intervene if thevehicle is backing up.
When driving, or when parking or exiting aparking space using Active Parking Assist,
PRE-SAFE®PLUS will not apply the brakes.
Function
PRE-SAFE®PLUS intervenes in certain situa-tions if the radar sensor system detects animminent head-on or rear-end collision.
PRE-SAFE®PLUS takes the following meas-ures depending on the hazardous situationdetected:
Rif the radar sensor system detects that ahead-on collision is imminent, the seat beltsare pre-tensioned.
Rif the radar sensor system detects that arear-end collision is imminent:
-the brake pressure is increased if thedriver applies the brakes when the vehicleis stationary.
-the seat belts are pre-tensioned.
The PRE-SAFE®PLUS braking application iscanceled:
Rif the accelerator pedal is depressed when agear is engaged
Rif the risk of a collision passes or is no lon-ger detected
Rif Active Distance Assist DISTRONIC indi-cates an intention to intervene
If the hazardous situation passes withoutresulting in an accident, the original settingsare restored.
Automatic measures after an acci-
dent
Immediately after an accident, the followingmeasures are implemented, depending on thetype and severity of the impact:
Rthe hazard warning lamps are switched on
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rthe electrically adjustable steering wheel israised when the driver's door is opened
Rthe engine is switched off and the fuel sup-ply is cut off
Rvehicles with Mercedes me connect: auto-matic emergency call

DNeutral
Do not shift the transmission toDwhile driving. The automatictransmission could otherwise bedamaged.
No power is transmitted from theengine to the drive wheels.
Releasing the brake pedal will allowyou to move the vehicle freely, e.g.to push it or tow it.
If ESP®is deactivated or faulty: shiftthe transmission to positionDifthe vehicle is in danger of skidding,e.g. on icy roads.
!Coasting in neutral\\maycause damage to the drive train.
:Drive
The automatic transmissionchanges gear automatically. Allforward gears are available.
Driving tips
Changing gear
The automatic transmission shifts through theindividual gears automatically when it is intransmission position[. This automatic gearshifting behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
Kickdown
Use kickdown for maximum acceleration.
XDepress the accelerator pedal beyond thepressure point.The automatic transmission shifts to a lowergear depending on the engine speed.
XEase off the accelerator pedal once thedesired speed is reached.The automatic transmission shifts back up.
Drive programs

Shift recommendation
All vehicles (except Mercedes-AMG vehi-
cles)
The gearshift recommendations assist you inadopting an economical driving style. The rec-ommended gear is shown in the multifunctiondisplay.
XShift to recommended gearDaccording togearshift recommendationCwhen shownin the multifunction display of the instru-ment cluster.
Mercedes-AMG vehicles

XShift to recommended gearDaccording togearshift recommendationCwhen shownin the multifunction display of the instru-ment cluster.
Upshifting (Mercedes-AMG vehicles)
!If manual gearshifting is permanently acti-vated, the automatic transmission does not
shift up automatically even when the enginelimiting speed for the current gear isreached. When the engine limiting speed isreached, the fuel supply is cut to preventthe engine from overrevving. Always makesure that the engine speed does not reachthe red area of the tachometer. There is oth-erwise a risk of engine damage.
CGear indicator
DUpshift indicator
Before the engine speed reaches the red area,an upshift indicator will be shown in the multi-function display.
XWhen theUPUPmessage appears in the multi-function display, pull on the right-handsteering wheel paddle shifter.
Kickdown
XFor maximum acceleration, depress theaccelerator pedal beyond the pressurepoint.The automatic transmission shifts to a lowergear depending on the engine speed.
XShift back up once the desired speed isreached.
During kickdown, you cannot shift gears usingthe steering wheel paddle shifters.
If you apply full throttle, the automatic trans-mission shifts up to the next gear when themaximum engine speed is reached. This pre-vents the engine from overrevving.
Mercedes-AMG vehicles:kickdown is onlypossible in the temporary setting.

Driving tips
General notes
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
Only operate this equipment when the vehi-
cle is stationary.
Observe the legal requirements for the countryin which you are driving. Some jurisdictionsprohibit the driver from using a mobile phonewhile driving a vehicle.
If you make a call while driving, always usehands-free mode. Only operate the telephonewhen the traffic situation permits. If you areunsure, pull over to a safe location and stopbefore operating the telephone.
Bear in mind that at a speed of only 30 mph(approximately 50 km/h), the vehicle covers adistance of 44 ft (approximately 14 m) persecond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to therecommended tire pressure.
RRemove unnecessary loads.
RWarm up the engine at low engine speeds.
RAvoid frequent acceleration or braking.
RObserve the service intervals in the Mainte-nance Booklet or in the service interval dis-play. Have all the maintenance work carriedin accordance with Daimler AG regulations.
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.

economical driving. A higher level indicates amore economical driving style. If the threeouter areas are completely filled at the sametime, the driver has adopted the most eco-nomical driving style for the selected settingsand prevailing conditions. The ECO displayborder lights up.
The ECO display does not indicate the actualfuel consumption. The additionally achievedrange displayed underBonus fr. startBonus fr. startdoesnot indicate a fixed consumption reduction.
In addition to driving style, the actual con-sumption is affected by other factors, such as:
Rload
Rtire pressure
Rcold start
Rchoice of route
Ractive electrical consumers
These factors are not included in the ECO dis-play.
An economical driving style specially requiresdriving at moderate engine speeds.
Achieving a higher value in the categories"Acceleration" and "Constant":
Robserve the gearshift recommendations.
Rdrive the vehicle in drive programCorE.
In urban traffic and stop-start traffic, drive pro-gramCis recommended.
On long journeys at a constant speed, e.g. onthe highway, only the outer area for "constant"will change.
The ECO display summarizes the driving stylefrom the start of the journey to its completion.Therefore, there are more marked changes inthe outer areas at the start of a journey. Onlonger journeys, there are fewer changes. Formore marked changes, perform a manual rest(Ypage 194).
Further information on the ECO display(Ypage 193).
Braking
Important safety notes
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
!On long, steep gradients, you must reducethe load on the brakes. To use engine brak-ing, shift to a lower gear in good time. Thishelps you to avoid overheating the brakesand wearing them out excessively.
When making use of the engine brakingeffect, it is possible that a drive wheel maynot turn for some time, e.g. in the case ofsuddenly changing or slippery road surfaceconditions. This could cause damage to thedrive train. This type of damage is not cov-ered by the Mercedes-Benz warranty.
Change into a lower gear in good time on longand steep downhill gradients. This is especiallyimportant if the vehicle is laden.
This also applies if you have activated cruisecontrol or Active Distance Assist DISTRONIC.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal
while driving, the braking system can over-
heat. This increases the stopping distance
and can even cause the braking system to
fail. There is a risk of an accident.
Never use the brake pedal as a footrest.
Never depress the brake pedal and the
accelerator pedal at the same time.
!Depressing the brake pedal constantlyresults in excessive and premature wear tothe brake pads.
If the brakes have been subjected to a heavyload, do not stop the vehicle immediately, butdrive on for a short while. This allows the air-flow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rainwithout braking, there may be a delayed reac-tion from the brakes when braking for the first

HEnvironmental note
Have the used tire sealant bottle disposed
of professionally, e.g. at a qualified special-
ist workshop.
If a tire pressure of 180 kPa(1.8 bar/26 psi)has been achieved after a maximum period often minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of thefaulty tire.
XStow the tire sealant bottle and the tireinflation compressor.
XPull away immediately.
XStop after driving for approximately tenminutes and check the tire pressure withthe tire inflation compressor.The tire pressure must now be at least130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot
repair the tire in this instance. Damaged
tires and a tire pressure that is too low can
significantly impair the vehicle's braking and
driving characteristics. There is a risk of
accident.
Do not continue driving. Contact a qualified
specialist workshop.
iIn cases such as the one mentionedabove, contact an authorized Mercedes-Benz Center. Or call 1-800-FOR-MERCedes(in the USA) or 1-800-387-0100 (in Canada).
XCorrect the tire pressure if it is still at least130 kPa (1.3 bar/19 psi). See the Tire andLoading Information placard on the driver'sside B-pillar or the tire pressure table in thefuel filler flap for values.
XTo increase the tire pressure:switch onthe tire inflation compressor.
XTo reduce the tire pressure:depress pres-sure release buttonmnext to pressuregagen.
XWhen the tire pressure is correct, unscrewthe filler hose from the valve of the sealedtire.
XScrew the valve cap onto the tire valve ofthe sealed tire.
XPull the tire sealant bottle out of the tireinflation compressor.
The filler hose remains attached to the tiresealant bottle.
XDrive to the nearest qualified specialistworkshop and have the tire changed there.
XHave the tire sealant bottle replaced assoon as possible at a qualified specialistworkshop.
XHave the tire sealant bottle replaced everyfour years at a qualified specialist workshop.
Battery (vehicle)
Important safety notes
Special tools and expert knowledge arerequired when working on the battery, e.g.removal and installation. You should thereforehave all work involving the battery carried outat a qualified specialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This
can lead to function restrictions applying to
safety-relevant systems, e.g. the lighting
system, the ABS (anti-lock braking system)
or the ESP®(Electronic Stability Program).
