ECO start/stop display (example: colour
multifunction display)
The ECO start/stop function automatically
switches the engine off when the vehicle
stops moving if:
R the è ECO symbol appears in the mul-
tifunction display in vehicles with black and white multifunction display
R the è ECO symbol appears in green in
the multifunction display in vehicles with a colour multifunction display
The ECO start/stop function is activated
whenever you switch on the engine using the key or the Start/Stop button.
If the ECO start/stop function has been man-
ually deactivated (Y page 148) or a malfunc-
tion has caused the system to be deactivated, the è symbol 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, then4, the
number of active cylinders, is also shown in
the è ECO symbol. This means that the
engine is operating with four cylinders.
If cylinder shut-off is not active, the engine
is operating with all eight cylinders. In this
case, 8, the number of active cylinders, is
shown in the èECO symbol. Automatic engine switch-off Operation
The ECO stop/start function is operational
and shows the following in the multifunction
display:
R the è ECO symbol in vehicles with a
black-and-white multifunction display
R a green èECO symbol in vehicles with a
colour multifunction display
This is the case if, among other things:
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

switch-off are met:
R the è ECO symbol does not appear in
vehicles with a black-and-white multifunc-
tion display
R a yellow èECO symbol appears in vehi-
cles with a colour multifunction display
i All of the vehicle's systems remain active
when the engine is switched off automati-
cally.
i All vehicles (except AMG vehicles):
automatic engine switch-off can take place a maximum of four times consecutively (ini-
tial stop, then three subsequent stops).
In vehicles with a black-and-white multi-
function display, the automatic engine
switch-off is then available again after the 146

Possible causes/consequences and
M
MSolutions The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be on and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 283). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X If the coolant temperature is below 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and stop-start traffic. Manual transmission
Gear lever
! Only engage gear when the clutch pedal is
depressed.
! When shifting between
5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift unintentionally into 3rdor4th gear
and damage the transmission.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise a risk of damaging the
clutch. Gear lever

Important safety notes
G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate. G
WARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake. i
Bear in mind that power transmission
between the engine and the transmission is interrupted when the engine is switched
off. For this reason, shift the automatic
transmission to Pwhen the engine is
switched off and the vehicle is stationary.
Apply the electric parking brake to prevent
the vehicle from rolling away. Selector lever

Automatic drive program
Automatic drive programs E and S Drive program
E(drive program Con AMG
vehicles) is characterised by the following:
R comfort-orientated engine and transmis-
sion settings.
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner.
R the vehicle pulling away more gently in
forward and reverse gears unless the accel-
erator pedal is depressed fully.
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example.
R the automatic transmission shifting up
sooner. This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin.
Drive program Sis characterised by the fol-
lowing:
R sporty engine and transmission settings
R the vehicle pulling away in first gear
R the automatic transmission shifting up
later
R as a result of the later automatic transmis-
sion shift points, the fuel consumption pos-sibly being higher

i Automatic downshifting occurs when
coasting.
Deactivating
If you have activated manual drive program
M, it will remain active for a certain amount of time. Under certain conditions the minimum
amount of time is extended, e.g. in the case of lateral acceleration, during an overrun phase
