Replacing bulbs
The front and rear light clusters of your
vehicle are equipped with LED light bulbs. Do
not replace the bulbs yourself. Contact a
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required.
Lamps 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. Windshield wipers
Switching the windshield wipers on/
off
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always
use washer fluid when operating the
windshield wipers.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
! Vehicles with a rain sensor: if the
windshield becomes dirty in dry weather
conditions, the windshield wipers may be
activated inadvertently. This could then
damage the windshield wiper blades or
scratch the windshield.
For this reason, you should always switch
off the windshield wipers in dry weather. 0047

X Switch on the power supply with the Start/

X Turn the combination switch to the
corresponding position.
In the 0062or0063 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0063 position, the rain sensor is more
sensitive than in the 0062position, causing
the windshield wipers to wipe more
frequently.
i Vehicles with MAGIC VISION CONTROL:
the washer fluid is fed through the wiper
blades and when wiping with washer fluid
00D4 the washer fluid is emitted directly
from the blades.
If the wiper blades are worn, the windshield
will no longer be wiped properly. This could
prevent you from observing the traffic
conditions. 146

Replacing the wiper blades
Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk
of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open the hood if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
! Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood.

Notes on using climate control
Automatic climate control Below, you can find a number of notes and
recommendations to help you use climate
control optimally.
R Activate climate control using the 0058
rocker switch. The indicator lamp in the
0058 rocker switch lights up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting"
function briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R 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 only be activated
or deactivated with the ignition switched
off. The residual heat function is switched
off when the ignition is switched on.
If you are controlling the rear climate control
using the front control panel, note the
following:
R If you set rear-compartment climate
control using the front control panel, the
00A4 symbol appears in the rear-
compartment control panel display.
R If the rear-compartment climate control is
set using the front control panel, it cannot
be set at the same time using the rear
control panel. If controlling the rear climate
control from the front control panel is
locked, wait five seconds. You will then be
able to control the rear climate control
using the rear control panel.
R After selecting the rear compartment
settings, the front climate control can be
controlled automatically again via
COMAND after five seconds. Alternatively, you can select "Cancel rear
compartment" in the COMAND air-
conditioning function bar.
