Operating safety
Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk
of fire.
When driving on an unpaved road or off-road,
check the vehicle underside regularly. In par-
ticular, remove trapped plant parts or other
flammable material. Contact a qualified spe-
cialist workshop immediately if damage is
detected.
GWARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
!There is a risk of damage to the vehicle if:
Rthe vehicle becomes stuck, e.g. on a highcurb or an unpaved road
Ryou drive too fast over an obstacle, e.g. acurb, a speed bump or a pothole in the road
Ra heavy object strikes the underbody orparts of the chassis
In situations like this, the body, the under-body, chassis parts, wheels or tires could bedamaged without the damage being visible.Components damaged in this way can unex-pectedly fail or, in the case of an accident, nolonger withstand the loads they are designedto.
If the underbody paneling is damaged, com-bustible materials such as leaves, grass ortwigs can gather between the underbody andthe underbody paneling. If these materialscome in contact with hot parts of the exhaustsystem, they can catch fire.
In such situations, have the vehicle checkedand repaired immediately at a qualified spe-cialist workshop. If on continuing your jour-ney you notice that driving safety is impaired,pull over and stop the vehicle immediately,paying attention to road and traffic condi-tions. In such cases, consult a qualified spe-cialist workshop.

Introduction

Bear in mind that at a speed of only 30 mph(approximately 50 km/h), the vehicle covers adistance of 44 ft (approximately 14m)per sec-ond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the rec-ommended tire pressure.
XRemove unnecessary loads.
XRemove roof racks when they are not needed.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave 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 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 with themanufacturer'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, 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.
CAcceleration
DCoasting

If Active Distance Assist DISTRONIC detects afaster-moving vehicle in front, it increases thedriving speed to the set speed.
Selecting the drive program
Active Distance Assist DISTRONIC supports asporty driving style when you have selected theSorS+, drive program (Ypage 145). Accelera-tion behind the vehicle in front or to the setspeed is then noticeably more dynamic. If youhave selected theCorEdriving program, thevehicle accelerates more gently. This setting isrecommended in stop-and-start traffic.
Changing lanes
If you change to the overtaking lane Active Dis-tance Assist DISTRONIC supports you if:
Ryou are driving faster than 45 mph (70 km/h)
Ryou switch on the appropriate turn signal
RActive Distance Assist DISTRONIC does notcurrently detect a danger of collision
If these conditions are fulfilled, your vehicle isaccelerated. Acceleration will be interrupted ifchanging lanes takes too long or if the distancebetween your vehicle and the vehicle in frontbecomes too small.
When you change lanes, Active Distance AssistDISTRONIC monitors the left lane on left-hand-drive vehicles or the right lane on right-hand-drive vehicles.
Stopping
GWARNING
If you leave the driver's seat when the vehicle
is only being braked by Active Distance Assist
DISTRONIC, it could roll away:
Rif there is a malfunction in the system or in
the voltage supply
Rif Active Distance Assist DISTRONIC is
deactivated using the cruise control lever,
for example by a vehicle occupant or from
outside the vehicle
Rif the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
Rif the battery is disconnected
Rif the vehicle is accelerated, e.g. by a vehi-
cle occupant
There is a risk of an accident.
Always deactivate Active Distance Assist
DISTRONIC and secure the vehicle against
rolling away before you leave it.
Further information on deactivating Active Dis-tance Assist DISTRONIC (Ypage 167).
If Active Distance Assist DISTRONIC detectsthat the vehicle in front is stopping, it brakesyour vehicle until it is stationary.
Once your vehicle is stationary, it remains sta-tionary and you do not need to depress thebrake.
After a time, the electric parking brake securesthe vehicle and relieves the service brake.
Depending on the specified minimum distance,your vehicle will come to a standstill at a suffi-cient distance behind the vehicle in front. Thespecified minimum distance is set using thecontrol on the cruise control lever.
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
