never be left unsupervised in the vehicle.
Always take the key with you when leaving the
vehicle, even if you are only leaving it for a
short time.
i The Start/Stop button can be used to
start the vehicle without inserting the key
into the ignition lock. The key must be in

General notes The ECO start/stop func
tion switches the
engin eoff automatically if th evehicle stops
moving.
The engine star tsautomatically when you pull
away again. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.
The ECO start/stop function is activated each
time the engine is switched on. The system is
operational when ECO symbol ¤is shown
in the multifunc tion display.
If the ECO star t/stop func tion is deactivated
(Y page 143), ECO symbol ¤is not
shown. G
WARNING
If the ECO symbol appears in the multifunc-
tion displa ywhen the engin eisswitched off,
the engine was switched off automatically.
However, all vehicle systems remain active. If
you open the door, unfasten your seat belt or
remove your foot from the brake pedal, the
engine will automatically start .The vehicle
ma ybegin moving. There is arisk of accident.
To prevent the vehicle from accidentally pull-
ing away, do not release the brake pedal until
you want to drive on. Do not leave the vehicle until you have
switched off the ignition and secured the vehi-
cle to prevent it from rolling away.
! Always switch the ignition off and take the
key with you when leaving the vehicle.
Automa tice ngine switch-off The ECO start/stop function switches the
engin
eoff automatically in certain situations.
To do this ,the vehicle must brake to astand-
still and the brakes must remain depressed
with the transmission in position Dor N.
The engine is only switched off if:
R the vehicle is at astandstill.
R the outside temperature is withi nthe range
that is suitable for the system.
R the engin eisatnormal operatin gtemper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the batter yissufficiently charged.
R the system detects that the windscreen is
not misted up when the air-conditioning
system is switched on.
R the bonnet is closed.
R the driver' sdoor is closed and the seat belt
is fastened.

engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or in amechanical
componen tofthe engin emanagement system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop, e.g. aMercedes-Benz Servic eCentre.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolan

coolant warnin glamp
may also be on and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 321). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct
,the radiator fa nmay be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X At coolant temperatures under 120 †, drive on to the nearest
qualified specialis tworkshop, e.g. to aMercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving on

WARNING
Only remove the key from the ignition lock
when the vehicle is stationary, as you can not
steer the vehicle when the key is removed.
Never leav echildren unsupervised in the vehi-
cle. They might release the electric parking
brake. This coul dlead to aserious or fatal
accident. G
WAR
NING
Under no circumstances should the exhaust
system come into contact with flammable
materials such as dry grass or petrol ,for
example. Do not par kthe vehicle on dry grass-
lan dorh arvested grain fields. The hot exhaust
system could otherwise ignite the flammable
material and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the electric parking brake must be applied.
R the transmission must be in position Pand
the key must be removed from the ignition
lock.
R on steep uphill or downhill gradients, turn
the fron twheels towards the kerb. Switching of

! Vehicles with adiesel particle filter:
If the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur durin gthe automa ticc leaning of the
diesel particle filter. This can lead to engine
damage. Therefore, if you frequently drive
short distances, make sure to drive on
motorways or countr yroads for 20 minutes

gtipsDriving and parking

G
WARNING
Make sure tha tother road user sare not
endang ered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing
atrailer,
yo um ust select shift range 1,2or 3in good
time.
i This als oapplies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Heavy and light loads G
WARNING
Never depress the brak epeda lconti nuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by apply ingc onstant slight
pedal pressure. This causes the brake system
to overheat, increases the brakin gdistance
and can lead to the brakes failing completely.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately ,but
drive on for ashort while. This allow sthe air-
flo wtoc ool the brakes mor equickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet road surface If driving in heavy rain for
aprolonged period
of time without braking, there may be a
delayed reaction from th ebrake swhen brak-
ing for the first time. This ma yalso occur after
the vehicle has been washed. You have to depress the brake pedal more
firmly. Maintain
agreater distance from the
vehicl einfront.
After driving on awet road or havin gthe vehi-
cle washed, brake firml ywhile paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protectin gthem against corro-
sion.
Limited braking perfo rmance on salt-
treated roads G
WARNING
The layer of salt on the brake discs and the
brake pads/linings may cause adelay in the
braking effect ,resultin ginas ignifican tlyl on-
ger brakin gdistance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully, without put-
ting other road users at risk, when you are
drivin gons alted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
R maintain agreater distance to th evehicle
ahead and driv ewith particular care.
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake discs.
New brake pads/linin gs G
WARNING
New brak epads/linings only reach their opti-
mum braking effect after several hundred kil-
ometres of driving. Before this optimum brak-
ing effect is reached, you shoul dcompensate
for the reduced brakin geffect by applying
greate rpressure when braking .This also
applies after the brake discs or the brake
pads/linings hav ebeen replaced.
For safety reasons, Mercedes-Benz recom-
mends that you only have brak epads/linings Driving tips
