WARNING
The reversing feature especially does not
react to soft, light and thin objects, such as
small fingers. This means that the reversing
feature cannot prevent someone being trap-
ped in these situations. There is a risk of
injury.

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 :
ECO start/stop display
If the ¤ symbol is shown in green in the
multifunction display, the ECO start/stop
function switches the engine off automati-
cally if the vehicle stops moving.
The stop/start function is automatically acti-
vated each time you start the engine with the ignition key.
If the ECO start/stop function has been man- ually deactivated (Y page 163) or a malfunc-
tion has caused the system to be deactivated, the ¤ symbol is not displayed.
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
¤symbol is displayed in green in
the multifunction display, if:
R the indicator lamp in the ECO button is lit
green
R the off-road program is deactivated (vehi-
cles with automatic transmission)
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

i All of the vehicle's systems remain active
when the engine is switched off automati-
cally.
i The engine can be switched off automat-
ically a maximum of four times (initial stop,
then three subsequent stops) in succes-
sion. The ¤symbol is shown in yellow in

Problem
Possible causes/consequences and
M
MSolutions Vehicles with a petrol
engine:
the engine is not run-
ning 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 con-
verter and damage it.
X Have the cause rectified immediately at a qualified specialist
workshop. 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 320). 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 to
5thand 6thgear, you
must press the shift lever to the right. Oth- erwise, you could shift unintentionally into
3rd or4th gear and damage the engine or
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.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing a trailer, you must shift into gear
1, 2or3in
good time. This uses the engine's braking
effect. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. Gear lever

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.
