Fuses and bulbs
CAUTION
● Alw
ays carefully remove the fuse box cov-
ers and refit them correctly to avoid problems
with your vehicle.
● Protect the fuse boxes when open to avoid
the entry
of dust or humidity. Dirt and humid-
ity inside fuse boxes can cause damage to
the electrical system. Note
● In the v
ehicle, there are more fuses than
those indicated in this chapter. These should
only be changed by a specialised workshop.
● Positions not containing a fuse do not ap-
pear in the f
ollowing tables.
● Some of the equipment listed in the tables
below per
tain only to certain versions of the
model or are optional extras.
● Please note that the above lists, while cor-
rect

Topic
introduction Read the additional information carefully

› page 52.
Changing bulbs requires a certain degree of
practical skill. If you choose to change the engine compart-
ment l
amps yourself, remember that it is a
dangerous area ››› in Work in the engine
c omp
artment on page 283.
Always use identical bulbs with the same
designation. The name can be found on the
base of the bulb holder.
Depending on how equipped the vehicle is,
there are different sets of headlights and tail
lights:
● Halogen headlights
● Full-LED main headlights*
● Rear bulb light
● LED rear light*
Fu
ll-LED headlight system*
Full-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the car and light bulbs cannot be
replaced. In case of headlight failure, go to
an authorised workshop to have it replaced. WARNING
● Tak
e particular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns. ●
Bu
lbs are highly sensitive to pressure. The
glass can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injur
e yourself on sharp edges, in particu-
lar on the headlight housing. CAUTION
● Remo
ve the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
befor
e changing a bulb.
● Take good care to avoid damaging any com-
ponents. For the sake of the environment
Please ask your specialist retailer how to dis-
po se of
used bulbs in the proper manner. Note
● Ple
ase check at regular intervals that all
lighting (especially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users.
● Before changing a bulb, make sure you
hav
e the correct new bulb.
● Do not touch the glass part of the bulb with
your b
are hands, use a cloth or paper towel
instead, since the fingerprints left on the » 93

In vehicles that do not have the correspond-
ing menu, this function can be deactivated in
a specialised workshop. WARNING
Improper or lack of use of the turn signals, or
f or
getting to deactivate them can confuse
other road users. This could result in a seri-
ous accident.
● Always give warning when you are going to
ch
ange lane, overtake or when turning, acti-
vating the turn signal in good time.
● As soon as you have finished changing
lane, o
vertaking or turning, switch the turn
signal off. WARNING
Incorrect use of the headlights may cause ac-
c ident
s and serious injury, as the main beam
may distract or dazzle other drivers. Note
● If the c
onvenience turn signals are operat-
ing (three flashes) and the other convenience
turn signals are switched on, the active part
stops flashing and only flashes once in the
new part selected.
● The turn signal only works when the igni-
tion is

lights also work when the ignition is switch-
ed off.
● If a trailer turn signal malfunctions, the
contr
ol lamp will stop flashing (trailer turn
signals) and the vehicle turn signal will flash
at double speed.
● The main beam he
adlights can only be
switched on if the dipped beam headlights
are already on.

The f
o
llowing conditions may prevent the
main beam headlight control from turning off the headlights in time or from turning off al-
tog
ether:
● In poorly lit towns with highly reflective
sign
s.
● Other insufficiently lit road users (such as
pedes
trians or cyclists).
● On tight bends and steep slopes (bumps)
and when oncomin
g vehicles are partially ob-
scured.
● When the drivers of other oncoming vehi-
cl
es (such as a truck) can see over a guard
rail in the centre of the road.
● If the camera is damaged or the power sup-
ply
is cut off.
● In fog, snow and heavy rain.
● With dust and sand turbulence.
● With loose gravel in the field of vision of
the camer
a.
● When the field of vision of the camera is
mis
ted up, dirty or covered by stickers, snow,
ice, etc. WARNING
The convenience features of the main beam
a s
sist should not encourage the taking of
risks. The system is not a replacement for
driver concentration.
● You are always in control of the main beam
and ad
apting it to the light, visibility and traf-
fic conditions. ●
It i
s possible that the main beam headlight
control does not recognise all driving situa-
tions and is limited under certain circumstan-
ces.
● When the field of vision of the camera is
dirty
, covered or damaged, operation of the
main beam control may be affected. This also
applies when changes are made to the vehi-
cle lighting system, for example, if additional
headlights are installed. CAUTION
To avoid affecting the operation of the sys-
t em, t
ake the following points into considera-
tion:
● Clean the field of vision of the camera regu-
larly
and make sure it is free of snow and ice.
● Do not cover the field of vision of the cam-
era.
● Chec
k that the windscreen is not damaged
in the are
a of the field of vision of the camera. Note
Main beam and headlight flasher can be
t urned on and off
