Lamps are an important aspect of vehicle safety.
You must therefore make sure that these func-
tion correctly at all times. Have the headlamp
setting checked regularly.

Windshield wipers
Switching the windshield wipers

!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected 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 resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield 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.

In the Ä orÅ position, the appropriate
wipin g frequency isset automatically according
to the intensity of the rain. Inthe Å position,
the rain sensor ismore sensitive than inthe
Ä position, causing the windshield wiper to
wipe more frequently.
If the wiper blades are worn, the windshield will
no longer bewiped properly. This could prevent
you from observing the traff icconditions.

Important safety notes
GWAR NING
If the wind shield wiper s begin to move while
you are changing the wiper blades, you could
be trapped bythe wiper arm. There isa risk of
injury.
Alwa ysswit ch off the windshield wiper s and
ignition before changing the wiper blades.
!To avoid damaging the wiper blades, make
sure that you touch only thewiper arm of the
wiper .
!Never open the hood ifawind shield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper armwithout a
wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. Ifyou release the
wind shield wiper armwithout a wiper blade
and itfalls onto the windshield, thewind shield
may bedamaged bythe force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
Replacing the wiper blades
Removing the wiper blades

or turn itto position 0(KEYLESS -GO).
XFold the wiper arm away from the windshield.
XFirmly press release knob :and pull wiper
blade ;upwards from the wiper arm in the
direction of the arrow.

Optimum use of automatic climate
control
Climate control system
Below, you can find a number of notes and rec-
ommendations to help you use climate control
optimally.
The 3-zone automatic climate control is only
available on vehicles for Canada.
RActivate climate control using the Ãand
¿ buttons. The indicator lamps above the
à and¿ buttons light up.
RVehicles with 3-zone automatic climate con-
trol: in automatic mode, you can also set the
climate mode (FOCUS, MEDIUM or DIFFUSE).
The MEDIUM level is recommended.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly 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.
RUse the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side and the rear compart-
ment as well. The indicator lamp above the
á button goes out.
RVehicles with 3-zone automatic climate con-
trol: 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.
RIf you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
ECO start/stop function
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
Ypage 126).

Switching cooling with air dehumidification on/off
General notes
If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will not
be cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up more
quickly. Therefore, deactivate the cooling with air-dehumidification function only briefly.
The "Cooling with air dehumidification" function is only available when the engine is running. The air
inside the vehicle is cooled and dehumidified according to the temperature selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is normal
and not a sign that there is a malfunction.
Switching on/off
XTo activate: press the¿button.

General notes
You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle from
outside. The air already inside the vehicle will
then be recirculated.
If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.

Switching the residual heat on or off
General notes
It is possible to make use of the residual heat of
the engine to continue heating the vehicle for
approximately 30 minutes after the engine has
been switched off. The heating time depends on
the set interior temperature.
The "residual heat" function only functions opti-
mally with the side windows and panorama roof
with power tilt/sliding panel closed.
