Pulling away with a trailer
To ensure that you do not roll back when pulling
away on an uphill slope, apply the parking brake.
XDepress the brake pedal and keep it
depressed.
XShift the automatic transmission to position
hork.
iAlways wait until the shifting process is
complete before driving off.
XRelease the parking brake (Ypage 123).
XRelease the brake pedal.
XCarefully depress the accelerator pedal.
Hill start assist
Hill start assist helps you when pulling away
forward 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 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 will not function if:
Ryou are pulling away on a level road or on a
downhill gradient
Rthe transmission is in position i
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 or when you
switch the drive program (except Mercedes-
AMG vehicles).
Mercedes-AMG vehicles: the ECO start/stop
function is activated after the engine is restarted
and is only available in drive program C. When
drive program Sor Mis selected, the ECO start/
stop function is deactivated.
The system is operational if all conditions for
automatic engine switch-off have been fulfilled
(
Ypage 108) and the èsymbol is shown in
green in the multifunction display.
If not all conditions for automatic engine switch-
off are fulfilled (
Ypage 108), the èECO
symbol is shown in yellow in the multifunction
display.
If the ECO start/stop function has been man-
ually deactivated (
Ypage 108) or a malfunction
has caused the system to be deactivated, the
è ECO symbol is not displayed.

Automatic drive program
Drive program E(drive program Con Mercedes-
AMG vehicles) is characterized by the following:
Rcomfort-oriented engine and transmission
settings.
Roptimal fuel consumption resulting from the
automatic transmission shifting up sooner.
Rthe vehicle pulls away more gently in forward
and reverse gears, unless the accelerator
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 shifts up later.
Rthe fuel consumption possibly being higher as
a result of the later automatic transmission
shift points.
Shift ranges
Introduction
It is not possible to set the shift range on
Mercedes-AMG vehicles.
When the automatic transmission is in position
D, it is possible to restrict or derestrict the shift
range.
The shift range selected is shown in the multi-
function display. The automatic transmission
shifts only as far as the selected gear.
Driving situations
=You can use the engine's braking
effect
5You can use the engine's braking
effect
This setting is particularly suited for
driving:
Ron steep mountain roads
Rin mountainous terrain
Rin arduous conditions
4The braking effect of the engine can
be utilized on extremely steep down-
hill gradients and long downhill
stretches.
Restricting the shift range
XPull the left-hand steering wheel paddle
shifter (Ypage 116).
The automatic transmission shifts down one
gear and restricts the shift range to the rele-
vant gear.
To protect against engine damage, the auto-
matic transmission:
Rdoes not shift down if doing so would cause
the engine to exceed the maximum engine
speed
Rshifts up, even if the shift range is restricted,
if the maximum engine speed for the shift
range is reached and you continue to accel-
erate
