Further information on holding the vehicle sta-
tionary on uphill gradients (Y page 148).ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
When pulling away again, the engine starts auto-
matically. The ECO start/stop function thereby
helps you to reduce the fuel consumption and
emissions of your vehicle.
Important safety notes G
WARNING
If the engine is switched off automatically and you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving. There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes :
ECO start/stop display
The ECO start/stop function is activated when-
ever you start the engine using the key or the
Start/Stop button.
If the è symbol is shown on the multifunction
display, the ECO start/stop function switches the engine off automatically if the vehicle stops
moving.
If the ECO start/stop function has been man-
ually deactivated (Y page 138) or a malfunction
has caused the system to be deactivated, the
è orç ECO symbol is not displayed.
Mercedes-AMG vehicles: the ECO start/stop
function is only available in drive program C.
Automatic engine switch-off General notes
The ECO start/stop function is operational and
the è ECO symbol is displayed on the mul-
tifunction display if:
R the indicator lamp in the ECO button is lit
green
R the outside temperature is within the range
that is suitable for the system
R the engine is at normal operating temperature
R the set temperature for the vehicle interior
has been reached
R the battery is sufficiently charged
R the system does not detect moisture on the
windscreen when the air-conditioning system
is switched on
R the bonnet is closed
R the driver's door is closed and the driver's
seat belt is fastened
If all conditions for automatic engine switch-off
are not fulfilled, the çECO symbol is shown.
All the vehicle's systems remain active when the engine is switched off automatically.
The engine can be switched off automatically a
maximum of four times (initial stop, then three
subsequent stops) in succession. The çECO
symbol is shown on the multifunction display
after the engine has been started automatically
for the fourth time. When the èECO symbol
is shown on the multifunction display, automatic
engine switch-off is possible again.

Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk of
fire and explosion.
Always touch the vehicle body before opening the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel can
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel. Otherwise, fuel can enter the fuel system.
Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. The repair costs are high. Notify a
qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can.
Do not get back into the vehicle during the refu-
elling process; Otherwise, electrostatic charge
could build up again.
If you overfill the fuel tank, some fuel may spray out when you remove the fuel pump nozzle.

In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or if there is a malfunction
in the system, it may not be possible to apply the
released parking brake.
X If this is the case, park the vehicle only on
level ground and secure it to prevent it from
rolling away.
X Vehicles with automatic transmission:
shift the automatic transmission to position
P.
X Vehicles with manual transmission:
engage first gear.
It may not be possible to release an applied
parking brake if the on-board voltage is low or if
there is a malfunction in the system. Contact a
qualified specialist workshop.
The electric parking brake carries out a function check at regular intervals when the engine is
switched off. Noises that occur are normal.

Important safety notes G
WARNING
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.
Drive sensibly – save fuel Observe the following tips to save fuel:
R The tyres should always be inflated to the rec-
ommended tyre pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not needed.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Have all maintenance work carried out as
indicated by the service intervals in the Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in cold weather, in stop-start traffic, on short jour-
neys and in hilly terrain. ECO display
