KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped with a
SmartKey featuring an integrated KEYLESS-GO
start function and adetachable Start/Stop but-
ton.
The Start/Stop button must be inserted in the
ignition lock and the SmartKey must be in the
vehicle.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the differentk ey
positions in the ignition lock. This is only the
case if you are not depressing the brake pedal. If you depress the brake pedal and press the
Start/Stop button
,the engine start simmedi-
ately.
Ac heck which periodically establishes aradio
connection between the vehicle and the Smart-
Key determines whether avalid SmartKey is in
the vehicle. This occurs,f or example, when
starting the engine.
To start the vehicle without actively using the
SmartKey:
Rthe Start/Stop button must be inserted in the
ignition lock.
Rthe SmartKey must be in the vehicle.
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (Ypage 65).
Do not keep the SmartKey:
Rwith electronic devices, e.g. amobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. ametal case.
This can impair the functionality of the KEY-
LESS-GO key.
If you lock the vehicle with the SmartKey's
remotec ontrol or with KEYLESS-GO, after a
short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou will not be able to start the engine with the
Start/Stop button until the vehicle is
unlocked again.
The engine can be switched off while the vehicle
is in motion by pressing and holding the Start/
Stop button for three seconds. This function
operates independently of the ECO start/stop
automatic engine switch-off function.

Drive sensibly –save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to the rec-
ommended tire pressure.
RRemove unnecessary loads.
RWarm up the engin eatlow engin espeeds.
RAvoid frequenta cceleration or braking.
RObserve the servicei ntervals in the Mainte-
nanc eBooklet or in the servicei nterval dis-play. Have all the maintenanc
ework carried in
accordance with Daimler AG regulations.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinkin gand driving and/or takin gdrugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can

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
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Thereforen ever leave
the engin erunning in enclosed spaces with-
out sufficientv entilation.
Certain engin esystems are designed to keep
the level of poisonous component sinexhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .Always have
work on the engin ecarried out at aqualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
BenzC enter for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at aqualified specialist
workshop.
The engin esettings must not be changed under
any circumstances. Furthermore, all specific
servicew ork must be carried out at regular
intervals and in accordance with the Mercedes-
Benzs ervicer equirements. Details can be found
in the Maintenance Booklet.

Important safety notes
ATTENTION ASSIST helps yo uduring long,
monotonous journeys, such as on highways .Itis

and 112 mph (180 km/h).
If ATTENTION ASSIST detects typica lindicators
of fatigueori ncreasing lapsesinc oncentration
on the part of the driver, it suggests yo utake a
break.
ATTENTION ASSIST assesses your level of fati-
gueorl apsesinc oncentration by taking the fol-
lowing criteria into account:

acteristics
Rjourney details, e.g. time of daya nd length of
journey The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or not
occurata
