system.
!Do not depress the accelerator pedal
when starting the engine.
iDuring a cold start, the engine runs at
higherspeeds to enable the catalytic
converter to reach its operating
temperature. The sound of the engine may
change during this time.
Automatic transmission
XShift the transmission to positionP.
Transmission position displayPis shown in
the multifunction display.
iWhen the transmission is in positionN,
you can also start the engine with the brake
pedal depressed.
Starting procedure
XTurn the SmartKey to position3in the
ignition lock (Ypage 137)and release it as
soonas the engine is running.
Pulling away
Automatic transmission
iIt is only possible to shift the transmission
from positionPto the desired position if
you depress the brake pedal.Only then can
the parking lock be deactivated.Ifyou do
not depress the brake pedal, the DIRECT
SELECT lever can still be moved but the
parking lock remains engaged.
iIf the transmission oil temperature is
below4‡(20†), you can only shift from
positionPwhen the engine is running.
XDepress the brake pedal and keep it
depressed.
XShiftthe transmission to positionDorR.
XRelease the brake pedal.
XCarefully depress the accelerator pedal.
The electric parking brake (Ypage 154) is
automatically released.
The red indicator lamp in the
instrumentcluster goes out.
iThe vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors fromthe inside at
any time.
You can also deactivate the automatic
locking feature (Ypage 208).
iUpshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill startassist
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
GWARNING
After a short time, hill start assist will no
longer brake your vehicle and it could roll
away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
XRemove your foot from the brake pedal.
The vehicle is then held for about a second.
XPull away.
Hill start assist is not active if:
Ryou are pulling away on a level road or on
a downhill gradient.
Rthe transmission is in positionN.

ECO start/stopfunction
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is
stopped undercertain 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 switchedoff 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\rsymbol is shown in green in the
multifunction display, the ECO start/stop
function switches the engine off
automatically if the vehicle stops moving.
The stop/start function is automatically
activated each time you start the engine with
the SmartKey.
If the ECO start/stop function has been
manually deactivated (Ypage 140) or a
malfunction has caused the system to be
deactivated, the\rsymbol is not
displayed.
AMG vehicles:the ECO start/stop function
is only available in drive programC.
Automatic engine switch-off
General notes
The ECO start/stop function is operational
and the\rsymbol is displayed in green in
the multifunction display, if:
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
temperature.
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.
If not all conditions for automatic engine
switch-off are fulfilled, the\rsymbol is
shown in yellow.
iAll of the vehicle's systems remain active
when the engine has been stopped
automatically.
iThe engine can be switched off
automatically a maximum of four times
(first stop and three subsequent stops) in
succession. The\rsymbol is shown in
yellow in the multifunction display after the
engine has been started automatically for
the fourth time. When the\rsymbol is
shown in green in the multifunction display,

Vehicles with automatic transmission
If the vehicle is braked to a standstill inDor
N, the ECO start/stop function switches off
the engine automatically.
iThe 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.
Automatic engine start
General notes
The engine starts automatically if:
Ryou switch off the ECO start/stop function
by pressing the ECO button.
Ryou engage reverse gearR.
Rthe vehicle starts to roll.
Rthe brake system requires this.
Rthe temperature in the vehicle interior
deviates from the set range.
Rthe system detects moisture on the

system is switched on.
Rthe condition of charge of the battery is too
low.
Rthe driver's seat belt is removed or the
driver's door is opened.
Vehicles with automatic transmission
The engine is started automatically if you:
Rrelease the brake pedal when HOLD is not
activated and the transmission is in
positionDorN.
Rdepress the accelerator pedal.
Rmove the transmission out of positionP.
iShifting the transmission to positionP
does not start the engine.

ProblemPossible causes/consequences and
Solutions
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.
XOnly depress the accelerator pedal slightly.
XHave the cause rectified immediately at a qualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic
converter and damage it.
The coolant
temperature display is
showing more than
248 ‡ (120 †). The
coolant warning lamp
may also be lit 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.
XStop as soon as possible and allow the engine and the coolant
to cool down.
XCheck the coolant level (Ypage 283). Observe the warning
notes as you do so and add coolant if necessary.

GWARNING
If the engine speed is above the idling speed
and you engage transmission positionDor
R, the vehicle could pull away suddenly. There
is a risk of an accident.
When engaging transmission positionDorR,
always firmly depress the brake pedal and do
not simultaneously accelerate.
GWARNING
The automatic transmission switches to
neutral positionNwhen you switch off the

XEase off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Rocking the vehicle free
Shifting the transmission repeatedly between
gearsDandRmay help to free the vehicle if
it has become stuck in slush or snow. The
vehicle's engine management system limits
the speed to a maximum of 5 mph (9 km/h)
when shifting back and forth. To shift back
