ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is
stopped under certain conditions.
The engine starts automatically when the
driver wants to pull away again. 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 0043
ECO start/stop display
If the 00A7 symbol is shown in green in the
multifunction display, the ECO start/stop
function switches the engine off
automatically if the vehicle stops moving.
Every time you switch on the engine using the
SmartKey or the Start/Stop button, the ECO
start/stop function is activated.
If the ECO start/stop function has been
manually deactivated (Y page 160) or a
malfunction has caused the system to be
deactivated, the 00A7symbol is not
displayed. AMG vehicles:
the ECO start/stop function
is only available in drive program C.
i AMG vehicles: if automatic cylinder shut-
off is active in drive program C, the number
of active cylinders 4is also shown in the
00A7 symbol. This means that the engine
is operating with four cylinders.
If cylinder shut-off is not active, the engine
will operate with all eight cylinders. In this
case, the number of active cylinders 8is
shown in the 00A7symbol.
For further information on automatic engine
switch-off (Y page 159) and automatic
engine start (Y page 160).
Automatic engine switch-off If the vehicle is braked to a standstill in
Dor
N, the ECO start/stop function switches off
the engine automatically.
The ECO start/stop function is operational
and the 00A7symbol 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
comfort range.
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 detects that the windshield is
not fogged up when the air-conditioning
system is switched on.
R the hood is closed.
R the driver's door is closed and the driver's
seat belt is fastened.
If conditions for automatic engine switch-off
have not been fulfilled, the 00A7symbol will
be shown in yellow.
i All of the vehicle's systems remain active
when the engine has been stopped
automatically. Driving

0050Solutions The engine does not
start. The HOLD function is activated.
X
Deactivate the HOLD function (Y page 195).
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 Turn the SmartKey back to position 0in the ignition lock before
attempting to start the engine again.
or
X Press the Start/Stop button repeatedly until all indicator lamps
in the instrument cluster go out.
X Try to start the engine again (Y page 157). 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. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak
or discharged.
X
Jump-start the vehicle (Y page 565).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop. 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. The engine is not
running smoothly and
is misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic
converter and damage it.
X Have the cause rectified immediately at a qualified specialist
workshop. 162

Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and
explosion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling. G
WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children. If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
R If fuel is swallowed, seek medical
assistance without delay. Do not induce
vomiting.
R Immediately change out of clothing which
has come into contact with fuel. G
WARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. 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. Any existing electrostatic buildup is
thereby discharged. 172
RefuelingDriving and parking

!
Do not use diesel to refuel vehicles with a
gasoline 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 could 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 refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.
