Important safety notes
G
Risk of injury
Very hot or very cold air can flow from the air
vents. This could cause burns or frostbite to
bare skin in the immediate vicinity of the
vents. Keep bare skin away from these air
outlets. If necessary, direct the airflow away
to a different area of the vehicle interior. In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R
keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves
R never cover the ventsora ir inlet and outlet
grilles in the vehicle interior
i For virtually draught-free ventilation,
adjust the sliders of the air vents to the

Risk of accident and injury
If the engine is switched off and the ECO sym-
bol is shown in green in the multifunction dis-
play, the engine has been switched off auto-
matically. All of the vehicle's 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.T
he
vehicle may begin moving. You could suffer
serious or even fatal injury or cause an acci-
dent resulting in injury or death.
Never leave the vehicle while the ECO symbol
in the multifunction display is shown in green
or yellow. Always secure the vehicle against
rolling away before leaving it.
! Always switch the ignition off and take the
key with you when leaving the vehicle.
Automatic engine switch-off The ECO start/stop function switches the
engine off automatically if the vehicle is
braked to a standstill and the brake remains
depressed with the transmission in position
D or N.
i You can still activate HOLD when the vehi-
cle is stationary, even if the engine has
been switched off automatically .Itis then
not necessary to continue applying the
brakes during the automatic stop phase.
When you depress the accelerator pedal,
the engine starts automatically and the
braking effect of the HOLD function is deac-
tivated. Depress the accelerator pedal
carefully, as the engine must be started
first.
The engine is only switched off if:
R the outside temperature is within the range
which is suitable for the system.
R the engine is at normal operating temper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently 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 front door is closed and the seat belt is
fastened. 132

M Solutions
The engine does not
start. The HOLD function or DISTRONIC PLUS is activated.
X
Deactivate the HOLD function (Y page 165) or DISTRONIC
PLUS (Y page 154).
X Try to start the engine again. The engine does not
start. The starter motor
can be heard. R
There is a malfunction in the engine electronics.
R There is a malfunction in the fuel supply.
X Before attempting to start the engine again, turn the key in the
ignition back to position 0or press the Start/Stop button
repeatedly until all indicator lamps in the instrumen tcluster go
out.
X Try to start the engine again (Y page 130). Avoid excessively
long and frequent attempts to start the engine as this will drain
the battery.
If the engine does not start after several attempts:
X Consult a qualified specialist workshop, e.g. a Mercedes-Benz
Service Centre. The engine does not
start
.The starter motor
can be heard. The
reserve fuel warning
lamp is lit and the fuel
gauge display shows 0. The fuel tank is empty.
X
Refuel the vehicle. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the starter battery is too
weak or discharged.
X
Jump-start the vehicle (Y page 294).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop, e.g. a Mercedes-Benz
Service Centre. The starter motor was exposed to a thermal load that was too high.
X
Allow the starter motor to cool down for approximately two
minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult a qualified specialist workshop, e.g. a Mercedes-Benz
Service Centre. 134

If you leave the vehicle parked up for longer
tha nfour weeks, the battery may be damaged
by exhaustive discharge.
X Disconnect the battery (Y page 292) or
connect it to a trickle charger.
i You can obtain information about trickle
chargers from a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre.
If you leave the vehicle parked up for longer
than six weeks, the vehicle may suffer dam-
age as a result of lack of use.
X Visit a qualified specialist workshop and
seek advice. Driving tips
General driving tips
Rolling with the engine switched off G
Risk of accident
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake, and you could therefore lose
control of the vehicle and cause an accident. Engine oil
! Vehicles with adiesel particle filter:
If the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning 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 country roads for 20 minutes
at least every 500 km. Brakes
Important safety notes G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden, you must select
shift range
1,2or 3in good time.
i This also applies 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. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously. Driving tips
149Driving and parking Z
not accelerate. This is based on the current
map data in the navigation system.
Roundabou
t(example)
The curren tspeed is maintained:
R approximately 10 seconds before the
roundabout/T junction and for approx-
imately 1.5 seconds when driving on the
roundabout
R approximately 12 seconds before reaching
a motorway exit and approximately 4sec-
onds after the motorway exit
Afterwards, the vehicle accelerates back to
the set speed you specified.
Stopping G
Risk of accident
Never get out of the vehicle when DISTRONIC
PLUS is activated.
DISTRONIC PLUS must also never be oper-
ated, activated or deactivated by a passenger
or from outside the vehicle.
DISTRONIC PLUS does not replace the park-
ing brake and must not be used for parking.
The DISTRONIC PLUS braking effect is can-
celled and the vehicle can start moving if:
R DISTRONIC PLUS is deactivated using the
cruise control lever.
R you accelerate.
R there is a malfunction in the system or an
interruption in the power supply, e.g. bat-
tery failure. R
the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
R the battery is disconnected.
If you wish to leave the vehicle or park it,
deactivate DISTRONIC PLUS and secure the
vehicle against rolling away.
If DISTRONIC PLUS detects that the vehicle
in fron tis stopping, it brakes your vehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle
in front.T he specified minimum distance is
set using the control on the cruise control
lever.
When DISTRONIC PLUS is activated, the
transmission is shifted automatically to posi-
tion Pif:
R the driver's door is open and the driver's
seat belt is unfastened.
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function.
R the bonnet is opened.
R a system fault occurs.
R the power supply is not sufficient.
