Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratch the glass if wiping takes place when the windscreen is dry.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
always operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto- matic car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscreen wipers may be activated
inadvertently. This could damage the wind- screen wiper blades or scratch the wind-
screen.
For this reason, you should always switch
off the windscreen wipers in dry weather. 1

Vehicles with a rain sensor: in theÄor
Å position, the appropriate wiping fre-
quency is automatically set according to the
intensity of the rain. In the Åposition, the
rain sensor is more sensitive than in the Ä
position, causing the windscreen wipers to
wipe more frequently.
If the wiper blades are worn, the windscreen
will no longer be wiped properly. This could
prevent you from observing the traffic condi-
tions. Replacing the wiper blades

If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of

Online display depends on the language
setting. The following are examples of
reversing camera messages in the
Audio 20/COMAND Online 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

Important safety notes The 360° camera is only an aid and may show
a distorted view of obstacles, show them
incorrectly or not at all. The 360° camera is
not a substitute for attentive driving.
You are responsible for safe manoeuvring and
parking. Make sure that there are no persons,
animals or objects in range while manoeu-
vring and parking.
You are always responsible for safety, and
must always pay attention to your surround-
ings when parking and manoeuvring. This
applies to the areas behind, in front of and
beside the vehicle. You could otherwise
endanger yourself and others.
The 360° camera will not function or will
function 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 the camera lenses mist up, e.g. when
driving into a heated garage in winter, caus- ing a rapid change in temperature R
if the camera lenses are dirty or covered
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° camera in this case. 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 camera in the rear area is protected by
means of a flap. This flap opens when the

on cleaning (Y page 401). For technical rea-
sons, the flap may remain open briefly after
the 360° camera has been deactivated.

! You can connect accessories with a
power rating of up to 240 W to the perma-
nent power supply and with a power rating of up to 180 W to the power supply that is
switched on via the ignition lock. The trailer battery may not be charged from
the power supply.
When it leaves the factory, your vehicle's
trailer socket is equipped with a permanent
power supply and a power supply that is
switched on via the ignition lock.
The permanent power supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin
10.
The trailer's permanent power supply is
switched off in the event of low vehicle supply
voltage and after six hours at the latest.
You can find more information about fitting
the trailer electrics at a qualified specialist
workshop.
X To switch the connected power supply
on or off: turn the key in the ignition lock to
position 2or 0respectively (Y page 181). Bulb failure indicator for LED lamps
If LED lamps are fitted in the trailer, an error
message may appear in the multifunction dis-
play even if there is no fault. The reason for
the error message may be that the current
has fallen below the minimum of 50 mA.
To ensure reliable operation of the bulb failure indicator, each LED chain in the trailer lighting
must be guaranteed a minimum current of
50 mA. Trailer with 7-pin connector
General notes Trailer with 7-pin connector:
you can con-
nect to the 13-pin socket on the ball coupling
using an adapter or, if necessary, an adapter
cable. Both can be obtained at a qualified
specialist workshop. Towing a trailer

General notes X
Turn the key to position 1in the ignition
lock (Y page 181).
The sockets can be used for accessories with a maximum draw of 180 W(15 A). Accesso-
ries include such items as bulbs or chargers
for mobile phones.
If you use the sockets for long periods when
the engine is switched off, the battery may
discharge.
An emergency cut-off ensures that the on-
board voltage does not drop too low. If the on-
board voltage is too low, the power to the
sockets is automatically cut. This ensures
that there is sufficient power to start the
engine.
If you have connected a device to the 12 V
socket, leave the cover of the stowage com-
partment open. This prevents the cover from
being blocked.
