You can open a door from inside the vehicle
even if it has been locked.
If a locked door is opened from the inside, the
previous unlock status of the vehicle will be
taken into consideration if:
Rthe vehicle was locked using the locking
button for the central locking, or
Rif the vehicle was locked automatically
The vehicle will be fully unlocked if it had pre-
viously been fully unlocked. If only the driver's

Important safety notes
GWARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
!The trunk lid swings upwards when
opened. Therefore, make sure that there is
sufficient clearance above the trunk lid.
!Only close the trunk once the roof is low-
ered completely. Otherwise, you could
damage the roof. If you close the trunk lid before the roof is
lowered completely, the loading aid switch
lights up and a warning tone sounds.
iOpening dimensions of the trunk lid
(
Ypage 608).
iWith the roof open, you can use the load-
ing aid (
Ypage 516) to raise the folded roof
in the trunk to make loading easier. For this
purpose, you can also open the trunk par-
tition.
The trunk partition must be closed again
after loading. It will otherwise not be pos-
sible to close the roof.
You can unlock the trunk lid if the vehicle is
stationary and the roof is completely open or
closed.
Do not leave the SmartKey in the trunk. You
could otherwise lock yourself out.
The trunk lid can be:
Ropened/closed from outside
Ropened and closed automatically from out-
side (vehicles with trunk lid remote closing
feature)
Ropened and closed automatically from
inside (vehicles with trunk lid remote clos-
ing feature)
Ropened, closed or stopped during opera-
tion without the use of your hands (vehicles with KEYLESS-GO and HANDS-FREE
ACCESS)

Trunk lid reversing feature
The trunk lid is equipped with an automatic
reversing feature. It reacts if a solid object
obstructs or restricts the trunk lid during the
closing procedure. The trunk lid opens again
automatically. The automatic reversing func-
tion is only an aid and is not a substitute for
your attentiveness to the trunk lid while it is
closing.

ECO start/stop function
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is stop-
ped 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
GWARNING
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
whenever you switch on the engine using the
SmartKey or the Start/Stop button.
If the engine has been switched off automat- ically by the ECO start/stop function, the è
ECO symbol is shown in the multifunc-
tion display.
Mercedes-AMG vehicles: the ECO start/
stop function is only available in drive pro-
gram C.

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
when:
Rthe indicator lamp in the ECO button is lit
green.
Rthe outside temperature is within the range that is suitable for the system.
Rthe engine is at normal operating temper-
ature.
Rthe set temperature for the vehicle interior
has been reached.
Rthe battery is sufficiently charged.
Rthe system detects that the windshield is
not fogged up when the air-conditioning
system is switched on.
Rthe hood is closed.
Rthe driver's door is closed and the driver's
seat belt is fastened.
iAll of the vehicle's systems remain active
when the engine is stopped automatically.
iAll vehicles (except Mercedes-AMG
vehicles): automatic engine switch-off can
take place a maximum of four times in a row
(initial stop, then three subsequent stops).
iMercedes-AMG vehicles: the number of
consecutive automatic engine switch-offs
is unlimited.
iThe HOLD function can be activated if the
engine has been switched off automati-
cally. It is then not necessary to continue

transmission does not shift up automati-
cally even when the engine limiting speed
for the current gear is reached. When the
