Starting the engine
Important safety notes
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
!Do not depress the accelerator when start-
ing the engine.
Starting procedure
XShift the automatic transmission to posi-
tion P.
The transmission position display in the mul-
tifunction display shows P.
iFor further information about the automatic
transmission, see (Ypage 118).
iIf you depress the brake when starting the
engine, pedal travel is unusually long and
there is less pedal resistance.
XMake sure that the parking brake is applied.
XTurn the SmartKey to position 3(Ypage 112)
in the ignition lock and release it as soon as
the engine is running.
iYou can also use the touch-start function. To
do this, turn the SmartKey to position 3
(
Ypage 112) and release it immediately. The
engine then starts automatically.
Pulling away
Automatic transmission
GWARNING
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.
!Only shift the automatic transmission to
reverse gear Ror park position Pwhen the
vehicle is stationary. Otherwise, the auto-
matic transmission could be damaged.
!Do not depress the accelerator pedal while
depressing the brake pedal. This impairs
engine performance and results in premature
wear on the brake system and drivetrain.
!If a warning tone sounds and the ReleasePark. Brakemessage appears in the multi-
function display, the parking brake is still
applied. Release the parking brake.
XDepress the brake pedal and keep it
depressed.
XShift the automatic transmission to position D
or R.
iBefore driving off, wait until the gear change
is fully completed.
XRelease the parking brake (Ypage 131).
XRelease the brake pedal.
XCarefully depress the accelerator pedal.
iIt is only possible to shift the automatic
transmission from position Pto a different
position if you depress the brake pedal. Only
then is the selector lever lock released.
iThe vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking feature (
Ypage 180).
iUpshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-

verter to reach its operating temperature
more quickly.
Hill start assist
GWARNING
After a short time, hill start assist will no lon-
ger 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.
Hill start assist helps you when pulling away for-
wards 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.
XTake your foot off the brake pedal.
iOnce you have taken your foot off the brake
pedal, the vehicle is held for around one sec-
ond.
XPull away.
Hill start assist will not function if:
Ryou are pulling away on a level road or on a
downhill gradient.
Rthe transmission is in position N.
Rthe parking brake is applied.
RESP®is malfunctioning.
ECO start/stop function
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
The ECO start/stop function switches the
engine off automatically when the vehicle stops
moving.
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.
The ECO start/stop function is activated each
time the engine is switched on.
The ECO start/stop function is only available in
drive program C/E.
The system is operational if all conditions for
automatic engine switch-off have been fulfilled
(
Ypage 115) and the èsymbol is shown in
green in the multifunction display.
In addition, the Stop/Start active
message
is shown in the AMG menu in the multifunction
display.
If not all conditions for automatic engine switch-
off are fulfilled (
Ypage 115), the èECO
symbol is shown in yellow in the multifunction
display.
In addition, the Stop/Start inactive
mes-
sage is shown in the AMG menu in the multi-
function display.
If the ECO start/stop function has been man-
ually deactivated (
Ypage 114) or a malfunction
has caused the system to be deactivated, the
è ECO symbol is not displayed.

automatic transmission shifting up sooner
Rthe vehicle pulling away more gently in
forward and reverse gears, unless the accel-
erator pedal is depressed fully
Rincreased sensitivity. This improves driving
stability on slippery road surfaces, for exam-
ple
Rthe 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 characterized by the follow-
ing:
Rsporty engine and transmission settings
Rthe vehicle pulling away in first gear
Rthe automatic transmission shifting up later
Rthe fuel consumption possibly being higher as
a result of the later automatic transmission
