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 Working in the en-
gine c omp
ar
tment on page 299.
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* Full-LED headlight system*
Ful
l-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 p
articular care when working on com-
ponents in the engine compartment if the en-
gine is warm. 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 edges, in particu-
lar on the headlight housing. CAUTION
● Remo v
e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
before c
hanging 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-
pose of u
sed bulbs in the proper manner. Note
● Ple a
se 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
have the c
orrect new bulb.
● Do not touch the glass part of the bulb with
your bar
e hands, use a cloth or paper towel
instead, since the fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, they will be deposited on
the reflector and will impair its surface.
● Depending on the level of equipment fitted
in the vehic
le, LEDs may be used for part or
all of the interior and/or exterior lighting.
LEDs have an estimated life that exceeds than
that of the car. If an LED light fails, go to an
authorised workshop for its replacement. 106
Operation
● If the s
u
nroof or sun blind will still not
close, visit a specialised workshop. WARNING
Closing the sunroof or sun blind without the
anti-trap f u
nction can cause serious injuries.
● Always be careful when closing the sunroof
and sun b
lind.
● No person should ever remain in the way of
the sunr
oof or sun blind, especially when
closing without the anti-trap function.
● The anti-trap function does not prevent fin-
gers
or other parts of the body from becom-
ing trapped against the roof frame and inju-
ries occurring. Lights and visibility

The driver is personally responsible for the
correct use and adjustment of the lights in all
situations.
Audible warnings to advise the driver that
the lights have not been switched off
If the key is not in the ignition and the driver
door is open, an audible warning signal is
heard in the following cases: this is a remind-
er to turn off the lights. ●
When the parkin
g light is on ››› page 145.
● When the light switch is in position or
. WARNING
The side lights or daytime running lights are
not bright enough t
o illuminate the road
ahead and to ensure that other road users are
able to see you.
● Always use your dipped beam head lights if
it is
raining or if visibility is poor. WARNING
If the headlights are set too high and not
used c orr
ectly, there is a risk of dazzling or
distracting other road users. This could result
in a serious accident.
● Always make sure that the headlights are
correctly
adjusted. Note
The legal requirements regarding the use of
vehic l
e lights in each country must be ob-
served. 144
Operation
●
In co l
d or damp weather conditions, the
headlights, tail lights and turn signals may
mist up inside temporarily. This is normal and
in no way effects the useful life of the vehicle
lighting system. Automatic dipped beam control
*The automatic dipped beam control is merely
intended a
s
an aid and is not able to recog-
nise all driving situations.
When the light switch is in position , the
vehicle lights and the instrument panel and

If the road is not well lit and other road users
cannot see the
vehicle well enough or at all,
accidents may occur. ●
The autom atic
dipped beam control ( )
only switches on the dipped beam when
there are no changes in brightness, and not,
for example when it is foggy. Main beam assist*
Main beam assist (Light Assist)
The main be
am a
ssist acts within the limits
of the system and depending on environmen-
tal and traffic conditions. Once switched on,
the system is activated as of a speed of
about 60 km/h (37 mph) and is deactivated
below about 30 km/h (18 mph) ››› .
When the sy s
t
em is activated and the camera
detects other vehicles that may be dazzled,
the main beam is automatically switched off.
Otherwise, the main beam is automatically
switched on.
The main beam assist generally detects illu-
minated areas and deactivates the main
beam when passing through a town, for ex-
ample. Switching the main beam assist on and off
Func-
tionUse
Activate:
– Switch the ignition on and turn the light
switch to position .
– From the base position, move the main
beam and turn signal lever forwards
››› page 145. When the warning lamp
is
displayed on the instrument panel display,
the main beam assist is switched on.
To switch system off:
– Switch off the ignition.
– OR: turn the light switch to a different po-
sition to
››› page 144.
– OR: with main beam on, move the main
beam and turn signal lever backwards.
– OR: move the main beam and turn the
signal lever forwards to manually switch
the main beam on. The main beam assist
will then be deactivated. Malfunctions
The f
o
l
lowing conditions may prevent the
main beam headlight control from turning off
the headlights in time or from turning off al-
together:
● In poorly lit towns with highly reflective
signs.
● Other in
sufficiently lit road users (such as
pedestri
ans or cyclists).
● On tight bends and steep slopes (bumps)
and when oncoming
vehicles are partially ob-
scured.

Operation
6. Use the warning triangle to draw the atten- tion of other r
o
ad users to your vehicle.
7. Always take the vehicle key with you when you le
ave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps
and the turn signal lamp in the switch will
flash at the same time. The simultaneous
hazard warning lights also work when the ig-
nition is switched off.
Emergency braking warning
If the vehicle brakes suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn the vehicles driving be-
hind. If you continue braking, the hazard
warning lights will come on automatically
when the vehicle comes to a standstill. They
switch off automatically when the vehicle
starts to move again. WARNING
● The risk of
an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Due to the high temperatures that the cata-
lytic con
verter can reach, never park in an
area where the catalytic converter could come into contact with highly inflammable materi-
al
s, f
or example dry grass or spilt petrol. This
could start a fire. Note
● The b atter
y will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
scribed her
e is subject to the relevant statu-
tory requirements. Parking lights
When the parking light is switched on, (right
or l
ef
t
turn signal), the front side light and
the rear light on the corresponding side of
the vehicle stay lit. The parking lights can on-
ly be activated with the ignition switched off
and the turn signal and main beam lever in
the central position, before being triggered.
Parking light on both sides With the ignition switched off and the light
sw
it
c
h in position , when locking the vehi-
cle from the outside, the parking lights on
both sides of the vehicle light up. In doing
so, only the side lights of both headlights
light up, and additionally the tail lights will
do so partially. Motorway light* The motorway light is available on vehicles
equipped w
ith f
ull-LED lights.
The function is connected/disconnected via
the corresponding Easy Connect system
menu.
● Activation: when going abo
ve 110 km/h
(68 mph) for more than 30 seconds, the dip-
ped beam raises slightly to increase the driv-
er's visibility distance.
● Deactivation: when reduc in
g the speed of
the car below 100 km/h (62 mph), the dip-
ped beam returns to its normal position.
Driving abroad The light beam of the dipped beam lights is
a
symmetric: the s
ide of
the road on which
you are driving is lit more intensely.
When a car that is manufactured in a country
that drives on the right travels to a country
that drives on the left (or vice versa), it is nor-
mally necessary to cover part of the headlight
bulbs with stickers or to change the adjust-
ment of the headlights to avoid dazzling oth-
er drivers.
In such cases, the regulations specify certain
light values that must be complied with for
designated points of the light distribution.
This is known as “Tourist light”.

Operation
Headlight wash/wipe system*
The he a
dlight
washers/wipers clean the
headlight lenses.
After the ignition is switched on, the first and
every fifth time the windscreen washer is
switched on, the headlights are also washed.
Therefore, the windscreen wiper lever should
be pulled towards the steering wheel when
the dipped beam or main beam are on. Any
incrusted dirt (such as insects) should be
cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work cor-
rectly in winter, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an anti-
icing spray. Note
The wiper will try to wipe away any obstacles
that ar
e on the windscreen. The wiper will
stop moving if the obstacle blocks its path.
Remove the obstacle and switch the wiper
back on again. Rain sensor*

lin g at
mor
e than 16 km/h (10 mph).
Rain sensor modified behaviour
Possible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 148 of
the rain sensor include:
● Damaged blades: a film of water on the
damag
ed blades may lengthen the activation
time, reduce the washing intervals or result
in a fast and continuous wipe.
● Insects: insects on the sensor may trigger
the winds
creen wiper.
● Salt on roads: in winter, salt spread in the
roa
ds may cause an extra long wipe when the
windscreen is almost dry.
● Dirt: dry dust, wax, coating on glass (Lotus
effect) or trac
es of detergent (car wash) may

Operation
WARNING
Never programme the auxiliary heater so that
it sw it
ches itself on and is running in an en-
closed space or an area with no ventilation.
The auxiliary heater exhaust fumes contain
carbon monoxide, an odourless and colour-
less toxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death. Operating instructions
The auxiliary heater exhaust system located
belo
w the
v
ehicle must be kept clear of snow,
mud and other objects. The exhaust fumes
must be able to exit freely. The emissions
generated by the auxiliary heater are re-
moved via an exhaust pipe fitted underneath
the vehicle.
On heating the vehicle interior, depending on
the outside temperature, the warm air is first
directed at the windscreen and then to the
rest of the vehicle interior through the air
vents. Directing the diffusers – towards the
windows for example – can affect air distribu-
tion.
When will the auxiliary heater not be activa-
ted?
● The auxiliary heater requires about as
much po w
er as the dipped beam headlights.
If the 12-volt battery charge is too low, the auxiliary heater switches off automatically
and cannot
be sw
itched on. This avoids prob-
lems when starting the engine.
● The heating must be activated every time
you want
to set off. Similarly, the departure
time must reactivate each time.
● The control lamp (fuel l
evel indicator)
lights up. Note
● Noise s
will be heard while the auxiliary
heater is running.
● When the air humidity is high and the in-
side temper
ature low, condensation from the
heating and ventilating system may evapo-
rate when the auxiliary heater is switched on.
In this case, steam may be released from un-
derneath the vehicle. This does not mean
that there is a vehicle malfunction.
● If the vehicle is tilted, e.g. if parked on a
slope, the operation of
the auxiliary heater
may be restricted if the fuel tank level is low
(just above the reserve level).
● If the auxiliary heater is used a number of
times f
or a long period of time, the 12-volt
battery will lose its charge. To recharge the
battery, the vehicle must be driven for a num-
ber of kilometres from time to time. As a
guideline: The journey should last approxi-
mately as long as the heater was connected.
● At temperatures below +5°C (+41°F), the
auxili
ary heater may switch itself on automat-
ically when the engine is switched on. The auxiliary heater is switched off again after a
cer
t
ain time.180
