Drive program E (Economy)
Drive programEis characterized by the follow-ing:
Rcomfort-oriented engine settings.
Roptimal fuel consumption resulting from theautomatic transmission shifting up sooner.
Rthe vehicle pulls away more gently in forwardand reverse gears, unless the acceleratorpedal is depressed fully.
Rthe vehicle has improved driving stability, forexample on slippery road surfaces.
Rthe automatic transmission shifting upsooner. This results in the vehicle being drivenat lower engine speeds and the wheels beingless likely to spin.
Rgliding mode is activated automatically whenengine-internal conditions are fulfilled andthe accelerator is not depressed. At the sametime the transmission’s clutch opens and thevehicle rolls freely using its kinetic energy. Asa result great distances can be completedwithout the engine brake and fuel consump-tion reduced.
iThe availability of gliding mode depends onvarious factors, including the following:
Rthe engine and transmission temperature
Rthe downhill gradient
Rthe vehicle speed
Rperforming regular adaptation functions
When you depress the brake pedal, glidingmode is deactivated, depending on pedalpressure.
When you activate cruise control or ActiveDistance Assist DISTRONIC, gliding mode isnot available.

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 vehicle
is stationary.
Observe the legal requirements for the countryin which you are driving. Some jurisdictions pro-hibit the driver from using a mobile phone whiledriving 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.

RThe tires should always be inflated to the rec-ommended tire pressure.
RRemove unnecessary loads.
RRemove roof racks when they are not needed.
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 the Main-tenance Booklet or by the service interval dis-play.
Fuel consumption also increases when driving incold weather, in stop-start traffic and in hilly ter-rain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious 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
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 in an enclosed space without ade-
quate 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 with themanufacturer's specifications. Always have
work 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, workrelevant to safety or on safety-related systemsmust be carried out at a qualified specialistworkshop.
The engine settings must not be changed underany circumstances. Furthermore, all specificservice work must be carried out at regularintervals and in accordance with the Mercedes-Benz service requirements. Details can be foundin the Maintenance Booklet.
ECO display
The ECO display shows you how economicalyour driving style is. The ECO display assists youin achieving the most economical driving stylefor the selected settings and prevailing condi-tions. Your driving style can significantly influ-ence the vehicle's consumption.

DCoasting

When Active Distance Assist DISTRONIC is acti-vated, the transmission is shifted automaticallyto position]if:
Rthe driver's seat belt is not fastened and thedriver's door is open.
Rthe engine is switched off, unless it is auto-matically switched off by the ECO start/stopfunction.
The electric parking brake is applied automati-cally if Active Distance Assist DISTRONIC isactive when the vehicle is stationary and:
Ra system malfunction occurs.
Rthe power supply is insufficient.
If a malfunction occurs, the transmission mayalso shift to position]automatically.
Setting a speed
Keep in mind that it may take a brief momentuntil the vehicle has accelerated or braked tothe speed set.
XPress the cruise control lever upCfor ahigher speed or downDfor a lower speed.
XTo adjust the set speed in 1 mph incre-ments (1 km/h increments):briefly pushthe cruise control lever upCor downDtothe pressure point.The last stored speed increases or decreasesin 1 mph (1 km/h) increments.
XTo adjust the set speed in 5 mph incre-ments (10 km/h increments):briefly pushthe cruise control lever upCor downDbeyond the pressure point.The last stored speed increases or decreasesin 5 mph (10 km/h) increments.
iActive Distance Assist DISTRONIC is notdeactivated if you depress the acceleratorpedal. If you accelerate to overtake, ActiveDistance Assist DISTRONIC adjusts the vehi-cle's speed to the last speed stored, after youhave finished overtaking.
Setting a specified minimum distance
You can set the specified minimum distance forActive Distance Assist DISTRONIC by varyingthe time span between one and two seconds.This determines the distance that Active Dis-tance Assist DISTRONIC is to maintain from thevehicle in front, depending on the road speed.You can see this distance in the multifunctiondisplay (Ypage 157).
The specified minimum distance can bechanged while Active Distance AssistDISTRONIC is switched on or off.
iMake sure that you maintain the minimumdistance to the vehicle in front as required bylaw. Adjust the distance to the vehicle in frontif necessary.
