Before changing any bulb, first turn off the
failed device. Do not touch the glass part of the bulb with
your bar
e hands. The fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, reducing bulb life and
causing condensation on the reflector sur-
face, thus reducing effectiveness.
A bulb must only be replaced by one of the
same type. The type is indicated on the bulb,
either on the glass part or on the base.
Xenon headlights
With this type of headlight, the user can re-
place the turn signal bulb. Replacement of
the dipped/main beam bulb must be done by
Technical Services, given that complex ele-
ments must be removed from the vehicle and
the automatic control system that incorpo-
rates it must be reset.
The Xenon bulbs discharge 2.5 times the
light flux and have an average lifespan of 5
times more than that of halogen bulbs, this
means that, except due to unusual circum-
stances, there is no need to change the bulbs
for the whole life of the vehicle. 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. » 83

Safety

Emergencies
●
The high v o
ltage element of gas discharge
bulbs* (xenon light) must be handled correct-
ly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not
to injure
yourself on sharp parts in the head-
light housing. CAUTION
● Remo v
e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights or parking lights be-
fore
you change a bulb. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of u
sed bulbs in the proper manner. Note
● Dependin g on w
eather conditions (cold or
wet), the front lights, the fog lights, the tail
lights and the turn signals may be temporari-
ly misted. This has no influence on the useful
life of the lighting system. By switching on
the lights, the area through which the beam
of light is projected will quickly be demisted.
However, the edges may continue to be mis-
ted.
● Please check at regular intervals that all
lighting (es
pecially the exterior lighting) on
your vehicle is functioning properly. This is not only in the interest of your own safety,
but
a
lso 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. The residue left by the fingerprints
would vaporise as a result of the heat gener-
ated by the bulb, they will be deposited on
the reflector and will impair its surface. Single headlight bulb change

Operation
All turn signals flash simultaneously when
the h az
ar
d 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 hazard warning
lights also work when the ignition is switch-
ed off. 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-
als, for example dry grass or spilt petrol. This
could start a fire. Note
● The batt er
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. Interior lights

Luggage compartment lighting
The light is activated when the rear lid is
open, even when the ignition and lights are
turned off. For this reason, ensure that the
rear lid is always closed.
Glove compartment light
When opening the glove compartment on the
passenger side, the glove compartment light
will automatically turn on and will turn off
upon closure.
Ambient light*
››› table on page 2
The ambient lighting lights up the central
console area and the footwell area.
They will switch on fully when the doors are
opened and will decrease in intensity while
driving when the dipped beam headlight is
on.
The intensity of the ambient light* can be ad-
justed using the Easy Connect menu (see
Adjusting Lights > Interior light-
ing ›››
page 24). Note
If not all the vehicle doors are closed, the in-
terior light s
will be switched off after approx.
10 minutes, providing the ignition key has
been removed and the courtesy light position
selected. This prevents the battery from dis-
charging. Visibility

Operation
Parking manoeuvre
● Place the vehicle in front of the parking
s p
ac
e and engage reverse gear (manual
gearbox) or move the selector to the R posi-
tion (automatic gearbox).
● Reverse slowly, and turn the steering wheel
so that the s
ide orientation lines lead to-
wards the parking space.
● Guide the vehicle into the parking space so
that the s
ide orientation lines run parallel to
it.

The CCS is able to maintain the set speed in
the range from approx. 30 km/h (19 mph) to
180 km/h (112 mph).
Once the speed setting has been saved, you
may take your foot off the accelerator.
When the cruise control is on and a speed is
programmed, the indicator on the instru-
ment panel* is lit.
If the cruise control system is switched off,
the symbol is switched off. The system will
also be switched off fully when the 1st gear
is engaged.*
Switching on the cruise control system
● Move the switch ›››
Fig. 182 1 towards the
l ef
t
to ON.
Setting speed
● Briefly press the lower part of the rocker
switc
h SET– ››› Fig. 182 2 once when you
h av
e r
eached the speed you wish to set.
When you release the rocker switch, the cur-
rent speed is set and held constant.
Switching off the cruise control system
● Move the control 1 towards the right to
OFF or t
urn the ignition off if
the vehicle is
stationary. WARNING
It could be dangerous to use the cruise con-
tro l
system if it is not possible to drive at con-
stant speed.
● Do not use the cruise control system when
driving in den
se traffic, on roads with lots of
bends or on roads with poor conditions (with
ice, slippery surfaces, loose grit or gravel), as
this could cause an accident.
● Always switch the cruise control system off
after u
sing it in order to avoid involuntary
use.
● It is dangerous to use a set speed which is
too high for the c
urrent road, traffic or weath-
er conditions. Risk of accident. Note
The cruise control cannot maintain a constant
speed when de s
cending downhill. It will in-
crease due to its own weight. Use the foot
brake to slow the vehicle. Adjusting the stored speed*
The speed can be altered without touching
the ac
c
el
erator or the brake.
Setting a higher speed
● Press the upper part of the rocker switch
RES+ ›››
