When unlocking, the turn signals flash once.
When locking, they flash three times.
You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated or deactivated using the on-board computer (Y page 219).
When it is dark, the surround lighting also comes

(Y page 218). KEYLESS-GO
General notes Bear in mind that the engine can be started by
any of the vehicle occupants if there is a KEY-
LESS-GO key in the vehicle (Y page 134).
Locking and unlocking centrally 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 KEYLESS-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.
When locking or unlocking with KEYLESS-GO,
the distance between the key and the corre-
sponding 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 vehicle. This occurs, for example:
R when the external door handles are touched
R when starting the engine
R whilst driving X
To unlock the vehicle: touch the inner sur-
face of the door handle.
X To lock the vehicle: touch sensor sur-
face :.
X Convenience closing feature: touch
recessed sensor surface ;for an extended
period.
For further information on the convenience
closing feature (Y page 86). X
To unlock the boot lid: pull the boot lid han-
dle.
The vehicle only unlocks the boot lid.
Deactivating and activating If you do not intend to use a key for an extended
period of time, you can deactivate the KEYLESS-
GO function of the key. The key will then use very
little power, thereby conserving battery power.
For the purposes of activation or deactivation,
the vehicle does not have to be nearby. Key

Reversing camera
General notes Reversing camera
:is an optical parking and
manoeuvring aid. It shows the area behind your vehicle with guide lines in the multimedia sys-
tem display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text shown in the multimedia system
display depends on the language setting. The following are examples of reversing camera
messages in the multimedia system 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 revers-
ing 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 there is a sudden change in temperature,
e.g. when driving into a heated garage in win-
ter R
if the camera lens is dirty or obstructed.
Observe the notes on cleaning
(Y page 293)
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 addi-
tional accessories on the rear of the vehicle (e.g.
licence plate holder, bicycle rack).
On vehicles with height-adjustable chassis,
leaving the standard height can result in inac-
curacies in the guide lines, depending on tech-
nical conditions.
i The reversing camera is protected from rain-
drops 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 process
R you switch off the engine
R you open the boot
See the notes on cleaning (Y page 293).
For technical reasons, the flap may remain
open briefly after the reversing camera has
been deactivated.
Activating/deactivating the reversing
camera X
To activate: make sure that the key is in
position 2in the ignition lock.

Important safety notes The 360° camera is only an aid and may show a
distorted view of obstacles, show them incor-
rectly or not at all. The 360° camera is not a
substitute for attentive driving.
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.
You are always responsible for safety, and must
always pay attention to your surroundings when parking and manoeuvring. This applies to the
areas behind, in front of and beside the vehicle.
You could otherwise endanger yourself and oth- ers. The 360° camera will not function or will func-
tion only in a limited manner:
R if the doors are open
R if the exterior mirrors are folded in
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 cameras are 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 win-
ter
R if the camera lenses are dirty or covered
R if the vehicle components in which the cam-
eras are fitted are damaged. In this event,
have the camera position and setting checked at a qualified specialist workshop.
Do not use the 360° camera under such cir-
cumstances. You could otherwise injure others
or damage objects when parking the vehicle.
Guide lines are always shown at road level. In
trailer mode, the guide lines are shown at the
level of the trailer coupling.
The field of vision and other functions of the
camera system may be restricted due to addi-
tional accessories on the rear of the vehicle (e.g.
licence plate holder, bicycle rack).
On vehicles with height-adjustable suspension,
due to the technical conditions, leaving the
