epending on the level of equipment
fitt ed in the
vehicle, LEDs may be used for
part or all of the interior and/or exterior light-
ing. LEDs have an estimated life that exceeds
that of the vehicle. If an LED light fails, go to
an authorised workshop for its replacement.

P o
s
ition the leads in such a way that
they cannot come into contact with any
moving parts in the engine compart-
ment.
Starting Start the engine of the vehicle with the
boosting battery and let it run at idling
speed.
Start the engine of the vehicle with the
flat battery and wait for 2 or 3 minutes
until the engine is running.
Removing the jump leads Before you remove the jump leads,
switch off the dipped beam headlights if
they are switched on.
Turn on the heater blower and heated
rear window in the vehicle with the flat
battery. This helps minimise voltage
peaks which are generated when the
leads are disconnected.
When the engine is running, disconnect
the leads in reverse order to the details
given above.

Changing bulbs
Gener a
l
notes Read the additional information carefully
› ›
›
page 63
Changing bulbs requires a certain degree of
practical skill.
If you choose to change the engine compart-
ment lamps yourself, remember that it is a
dangerous area ››› in Safety notes for work
in the en gine c
omp
artment on page 273.
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 diff
erent sets of headlights and tail
lights:
● Halogen headlights.
● Full-LED main headlights*
● Halogen headlights with LED daytime run-
ning lights*
● Re
ar bulb light
● LED rear light*
Ful
l-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 vehicle and the bulbs cannot
be replaced. In case of headlight failure, go
to an authorised workshop to have it re-
placed. WARNING
● Tak e p
articular care when working on com-
ponents in the engine compartment if the en-
gine is warm, there is a risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure
yourself on sharp parts in the head-
light housing. 106

The driver is personally responsible for the
correct use and adjustment of the lights in all
situations. Note
● The le g
al requirements regarding the use of
vehicle lights in each country must be ob-
served.
● The dipped beam headlights will only work
with the ignition on. The s
ide lights come on
automatically when the ignition is turned off.
● If the lights are left on after the key has
been taken out
of the ignition lock, an audi-
ble warning sounds while the driver door re-
mains open. This is a reminder to switch the
lights off.
● The use of the lighting described here is
subj
ect to the relevant statutory require-
ments. Automatic lighting*
Activation
– Rotate the switch to the po
sition, this
indication will light up.
Deactivation
– Turn the light switch to .
Automatic
lighting
If automatic headlight control is switched on,
dipped beam headlights are automatically
switched on by a photosensor if you drive in-
to a tunnel, for example. WARNING
● Ev en if
the automatic headlight control is
switched on, the dipped beam headlights will
not be switched on with fog. Therefore, the
dipped beam must be switched on manually. Note
● For v
ehicles with the automatic headlight
system, when the key is removed from the ig-
nition, the audible warning will only sound if
the light knob is in position .
● The use of the lighting described here is
subj
ect to the relevant statutory require-
ments. ●
Do not p ut
stickers on the windscreen in
front of the sensor. This may cause disrup-
tions or faults in the automatic lighting sys-
tem.
● The rain sensor switches on the dipped
beam hea
dlights when the windscreen wipers
have been operating continuously for a few
seconds and it switches the lights off when
the continuous or interval wipe is switched
off for some minutes. Daytime running lights
The daytime running lights consist of individ-
ual
lights, int
e
grated in the front headlights.
By connecting the daytime running lights,
these lights are switched on 1)
››› .
The d a
ytime ru
nning lights switch on every
time the ignition is switched on, if the switch
is in positions or , according to the level
of exterior lighting.
When the light switch is in position , a
light sensor automatically switches dipped
beam on and off (including the control and
instrument lighting) or the daytime running
lights depending on the level of exterior
lighting. 1)
On vehicles equipped with rear LED lights, the rear
side light i
s switched on as well.

Lights and visibility
WARNING
● Never driv e w
ith daytime lights if the road
is not well lit due to weather or lighting con-
ditions. Daytime lights do not provide
enough light to illuminate the road properly
or be seen by other road users.
● On vehicles with rear lights with bulbs,
when activating the d
aytime running light
the rear lights are not switched on. A vehicle
which does not have the rear lights on may
not be visible to other drivers in the dark-
ness, in the case of heavy rain or in condi-
tions of poor visibility. Fog lights

lights or the headlight flasher if they could
dazzle other drivers. Note
● If the c on
venience turn signals are operat-
ing (three flashes) and the other convenience
turn signals are switched on, the active part

ing lamp flashes in the instrument pan-
el. The control lamp flashes when the turn
signals are operated, provided a trailer is cor-
rectly attached and connected to the vehicle.
If a turn signal bulb is defective, the control
lamp flashes at double speed. If the trailer
turn signal bulbs are defective, the control
