WARNING
Bulbs, lamps and plug connectors can
become very hot during use. When replacing a bulb, you could burn yourself on these com-
ponents. There is a risk of injury. Allow these components to cool down before
replacing the bulb.
Do not use a bulb if it has been dropped or if its
glass tube has been scratched.
The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Use bulbs only in closed lamps that have been
designed for this purpose. Fit only spare bulbs of the same type and the specified voltage.
Marks on the glass tube reduce the service life
of the bulb. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Replace only the bulbs listed (Y page 126).
Have the bulbs that you cannot replace yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb does not light up either, consult
a qualified specialist workshop.
Headlamps and lamps are an important aspect
of vehicle safety. You must therefore make sure

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 col-
lected on the windscreen can scratch the
glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen 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 wind- screen with washer fluid after an automatic
car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windscreen becom-
ing dirty in dry weather conditions, the wind-
screen wipers may be activated inadvertently. This could damage the windscreen wiper
blades or scratch the windscreen.
For this reason, you should always switch off
the windscreen wipers in dry weather. Combination switch

X Turn the key to position 1or 2in the ignition

X Turn the combination switch to the corre-
sponding position.
In the ÄorÅ position, the appropriate
wiping frequency is set automatically according to the intensity of the rain. In the Åposition,
the rain sensor is more sensitive than in the
Ä position, causing the windscreen wiper to
wipe more frequently.
Vehicles with MAGIC VISION CONTROL: the
washer fluid is fed through the wiper blades and when wiping with washer fluid îthe washer
fluid is emitted directly from the blades.
If the wiper blades are worn, the windscreen will
no longer be wiped properly. This could mean
you are unable to observe the traffic conditions. 128

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.
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 341)
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).
For technical reasons, leaving the standard
height can result in inaccuracies in the guide
lines on vehicles with a height-adjustable chas-
sis.
i The reversing camera is protected from rain-
drops and dust by 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 luggage compartment See the notes on cleaning (Y
page 341).
For technical reasons, the flap may remain
open briefly after the reversing camera has
been deactivated.

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 responsible for safety at all times and
must always pay attention to your surroundings when parking and manoeuvring. This applies to
the areas behind, in front of and beside the vehi- cle. You could otherwise endanger yourself and
others.

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
standard height can result in the following:
R Inaccuracies in the guide lines
R Inaccuracies in the display of generated
images (top view)
