open a side window slightly to reduce or elim-
inate these noises.
Sliding sunroof reversing feature
In the following section, the term "sliding sun-
roof" refers to the panorama roof with power
tilt/sliding panel.
The sliding sunroof is equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts the sliding sunroof during the closing
process, the sliding sunroof opens again auto-
matically. However, the automatic reversing
feature is only an aid and does not relieve you of
the responsibility of paying attention when clos-
ing the sliding sunroof.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 1/6 in (4 mm) of the closing
movement
Rduring resetting
Rwhen closing the sliding sunroof again man- ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rpress the switch in any direction during the
automatic closing process
The closing process is stopped.

Start/Stop button
General notes
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS-
GO function and a detachable Start/Stop but-
ton.
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different Smart-
Key positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
To start the vehicle without actively using the
SmartKey:
Rthe Start/Stop button must be inserted in the
ignition lock.
Rthe SmartKey must be in the vehicle.
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (Ypage 70)
Do not keep the KEYLESS-GO key:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the SmartKey remote
control or with KEYLESS-GO, after a short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou will no longer be able to start the engine
with the Start/Stop button until the vehicle is
unlocked again
If you lock the vehicle centrally using the button
on the front door (
Ypage 75), you can continue
to start the engine with the Start/Stop button.

Pulling away
General notes
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.
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 (
Ypage 184).
It is only possible to shift the transmission from
position Pto the desired position 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

At transmission fluid temperatures below Ò4 ‡
(Ò20 †), you can only shift out of park position Pinto another transmission position when the
engine is running.
iUpshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.
Information on the automatic release of the
electric parking brake (
Ypage 142).
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.
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 is not active if:
Ryou are pulling away on a level road or on a
downhill gradient.
Rthe transmission is in position N.

ECO start/stop function
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.
