Pulling away
General notes
G
WARNING
If the engine speed is above the idling speed
and you engage transmission position
7
or
C
, the vehicle could pull away sud-
denly. There is a risk of an accident.
When engaging transmission position
7
or
C
, always firmly depress the brake
pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The 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 (
Y
page 199).
Vehicles with automatic transmission: it is
possible to shift the transmission from posi-
tion
j
to the desired position only if you
depress the brake pedal. Only then can the
parking lock be deactivated.
All vehicles (except Mercedes-AMG vehi-
cles): if you do not depress the brake pedal,
the DIRECT SELECT lever can still be moved
but the parking lock remains engaged.
Mercedes-AMG vehicles: if you do not
depress the brake pedal, the selector lever can
still be moved but the parking lock remains
engaged.
At transmission fluid temperatures below

4 ‡
(

j
into another transmission position when the
engine is running.

Upshifts take place at higher engine
speeds after a cold start. This helps the cat-
alytic converter to reach its operating tem-
perature more quickly.

electric parking brake (

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.
G
WARNING
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 is not active if:
R
you are pulling away on a level road or on a
downhill gradient.
R
the transmission is in position
i
.
R
the electric parking brake is applied.
R
ESP

is malfunctioning.
