Hill start assist 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. G
WARNING
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.

Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is
stopped under certain 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.

General notes 0043
ECO start/stop display
If the 00A7 symbol is shown in green in the
multifunction display, the ECO start/stop
function switches the engine off
automatically if the vehicle stops moving.
Every time you switch on the engine using the

deactivated, the 00A7symbol 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, the number
of active cylinders 4is also shown in the
00A7 symbol. This means that the engine
is operating with four cylinders. Driving
