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.
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehi- cle. This occurs, for example, when starting
the engine.
To start the vehicle without actively using the
key:
R the Start/Stop button must be inserted in
the ignition lock
R the key must be in the vehicle
R the vehicle must not be locked with the key
or KEYLESS-GO (Y page 85)
Do not keep the key:
R with electronic devices, e.g. a mobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality.
If you lock the vehicle with the key's remote
control or with KEYLESS-GO, after a short
time:
R you will not be able to switch on the ignition
with the Start/Stop button
R you will not 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 but- ton on the front door (Y page 91), you can
continue to start the engine with the Start/
Stop button.
The engine can be switched off while the vehi-
cle is in motion by pressing and holding the
Start/Stop button for three seconds. This
function operates independently of the ECO
start/stop automatic engine switch-off func-
tion. Key positions with the Start/Stop button

General notes G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or if there is a malfunc-
tion in the system, it may not be possible to
apply the released parking brake.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it from
rolling away.
X Shift the automatic transmission to posi-
tion P.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
if there is a malfunction in the system. Con-
tact a qualified specialist workshop. The electric parking brake carries out a func-
tion check at regular intervals when the
engine is switched off. Noises that occur are
normal.

General notes Reversing camera
:is under a flap in the
boot lid.
Reversing camera :is an optical parking
and manoeuvring aid. It shows the area
behind your vehicle with guide lines in the
COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text shown in the COMAND display
depends on the language setting. The fol-
lowing are examples of reversing camera
displays in the COMAND display.
Important safety notes The reversing camera is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals
or objects in range while manoeuvring and
parking. Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R if the boot lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if the camera lens mists up, e.g. when driv-
ing into a heated garage in winter, causing
a rapid change in temperature
R if the camera lens is dirty or obstructed.
R if the rear of your vehicle is damaged. In this
case, have the camera position and setting checked at a qualified specialist workshop.
The field of vision and other functions of the
reversing camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. licence plate holder, bicycle rack).
The guide lines in the COMAND display show the distances to your vehicle. The distances
only apply to road level.
i The reversing camera is protected from
raindrops and dust by means of a flap.
When the reversing camera is activated,
this flap opens.
The flap closes again when:
R you have finished the manoeuvring proc-
ess
R you switch off the engine
R you open the boot
Observe the notes on cleaning
(Y page 350).
For technical reasons, the flap may remain
open briefly after the reversing camera has been deactivated. 220

R if the vehicle components in which the
cameras are fitted are damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop.
Do not use the 360° under such circumstan-
ces. You could otherwise injure others or
damage objects when parking the vehicle.
The guide lines in the COMAND display show
the distances to your vehicle. The distances
only apply to road level.
i The camera in the rear area is protected
from raindrops and dust by means of a flap.

See the notes on cleaning (Y page 350).
For technical reasons, the flap may remain
open briefly after the 360° camera has
been deactivated. On vehicles with height-adjustable chassis,
depending on technical conditions, leaving
the standard height can result in:
R inaccuracies in the guide lines
R inaccuracies in the display of generated
images (top view)
Activation conditions The 360° camera image can be displayed if:
R COMAND Online is switched on (see the
separate operating instructions)
R the 360° camera 360° camera function is switched on

WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for
the country in which you are currently driving when operating the on-board computer. G
WARNING
If the instrument cluster has failed or there is a malfunction, you may not know about
safety-related function restrictions. The oper-ating safety of your vehicle may be affected.
There is a risk of an accident.
Immediately stop the vehicle while paying
attention to the traffic conditions and consult
a qualified specialist workshop. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating safety of your vehicle may be impaired. There
is a risk of an accident.
