Important safety notes
G
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 beforereplacing 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 bulbs. 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. Replacing bulbs
121Lights and windscreen wipers Z

Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Replace only the bulbs listed (Y page 122).
Have the bulbs that you cannot change yourself replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop.
Headlamps and lights are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times. Have
the headlamp setting checked regularly.
Vehicles with LED headlamps: the front and
rear lamp clusters of your vehicle are equipped
with LED bulbs. Do not replace the bulbs your-
self. Contact a qualified specialist workshop
with the necessary specialist knowledge and
tools to carry out the work required. Overview of bulb types
You can replace the following bulbs. The details for the bulb type can be found in the legend. Halogen headlamps

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. Windscreen wipers
123Lights and windscreen wipers Z

For this reason, you should always switch off
the windscreen wipers in dry weather. 1

Vehicles with a rain sensor: in theÅor
Ä position, the appropriate wiping frequency
is automatically set according to the intensity of
the rain. In the Åposition, the rain sensor is
more sensitive than in the Äposition, caus-
ing the windscreen wiper to wipe more fre-
quently.
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. Replacing the wiper blades
Important safety notes G
WARNING
If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades. !
Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen.
Never fold a windscreen wiper arm without a
wiper blade back onto the windscreen.
Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release the
windscreen wiper arm without a wiper blade
and it falls onto the windscreen, the wind-
screen may be damaged by the force of the
impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.

J To set the airflow (Y page 132) Notes on using automatic climate
control
Optimum use of automatic climate con-
trol The following contains notes and recommenda-
tions on how best to use THERMATIC automatic
climate control or THERMOTRONIC.
R Activate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with dehumidification" function is activated in
automatic mode.
R Set the temperature to 22 †.
R Use the "Windscreen demisting" function only
briefly until the windscreen is clear again.
R Use the "Air-recirculation mode" function only
briefly, e.g. if there are unpleasant outside
odours or when in a tunnel. The windows
could otherwise mist up as no fresh air is
drawn into the vehicle in air-recirculation
mode.
R Vehicles with THERMATIC with auxiliary heat-
ing or THERMOTRONIC: use the "Residual
heat" function if you want to heat or ventilate
the vehicle interior when the ignition is
switched off. The "Residual heat" function can
be switched on or off only with the ignition
switched off. The "Residual heat" function is
switched off when the ignition is switched on.

Mercedes-AMG vehicles) You can choose between various drive programs
with the DYNAMIC SELECT switch
(Y page 152).
If you have selected drive program E:
R during heating, the electrical heater booster
is deactivated and heat output is reduced as a
result
