ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stop-
ped under certain conditions.
When pulling away again, the engine starts
automatically. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption 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 :

If the è ECO symbol is shown in green in
the multifunction display, the ECO start/stop function switches the engine off automati-
cally once the vehicle stops moving.
If the ECO start/stop function has been man-
ually deactivated (Y page 166) or a malfunc-
tion has caused the system to be deactivated,
the è ECO symbol is not displayed. The ECO start/stop function is only available
in drive program E(drive program Con
Mercedes-AMG vehicles).
Automatic engine switch-off If the vehicle is braked to a standstill with the
transmission in Dor N, the ECO start/stop
function switches off the engine automati-
cally.
The ECO start/stop function is operational
and the èECO symbol is displayed in
green in the multifunction 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 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 driver's door is closed and the driver's
seat belt is fastened
If the conditions for automatic engine switch- off are not all met, the èECO symbol is
shown in yellow.
All of the vehicle's systems remain active
when the engine is switched off automati-
cally.
The HOLD function can be activated if the
engine has been switched off automatically. It is 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 deactivated.

Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
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. 178
RefuellingDriving and parking

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.
Do not get into the vehicle again during the
refuelling process. Otherwise, electrostatic
charge could build up again.
! 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.
! 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 par- ticles from the fuel can. If you overfill the fuel tank, some fuel may
spray out when you remove the fuel pump
nozzle.
