When the locator lighting is activated in Audio
20/COMAND Online, it lights up when it is
dark after the vehicle is unlocked with the
remote control (see separate operating
instructions). You can also set an audible signal to confirm
that the vehicle has been locked. The audiblesignal can be activated or deactivated using
the on-board computer (Y page 252). KEYLESS-GO
General notes Bear in mind that the engine can be started by
any of the vehicle occupants if there is a key
in the vehicle.
Locking and unlocking You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you need to carry
the key with you. You can combine the KEY-
LESS-GO functions with the functions of a
conventional key. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using
the & button on the key.
The driver's door and the door at which the
handle is used must both be closed. The key
must be outside the vehicle. When locking or unlocking with KEYLESS-GO, the distance
between the key and the corresponding door
handle must not be greater than 1 m.
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:
R when starting the engine
R whilst driving
R when the external door handles are
touched
R during convenience closing Key

General notes Reversing camera
:is an optical parking
and manoeuvring aid. It uses guide lines to
show the area behind your vehicle in the
Audio/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 Audio/COMAND
display depends on the language setting.
The following are examples of reversing
camera displays in the Audio/COMAND
display.
See the notes on cleaning (Y page 333).
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. Driving systems
217Driving and parking Z

Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R if the tailgate 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 there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed.
Observe the notes on cleaning
(Y page 333)
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).
