WARNING
The windshield will not longer be wiped
properly if the wiper blades are worn. This
could prevent you from observing the traffic
conditions, thereby causing an accident.
Replace the wiper blades
twice a year, ideally
in spring and fall.
! 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/rear
window can scratch the glass if wiping
takes place when the windshield/rear
window 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/rear window after the
vehicle has been washed in an automatic
car wash, this may be due to wax or other
residue. Clean the windshield/rear window
with washer fluid after an automatic car
wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield
becoming 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. Combination switch

X Switch on the ignition.
X Turn the combination switch to the
corresponding position.
Intermittent wiping is interrupted if you stop
and open a front door. This protects people
getting into and
out

of the vehicle from being
sprayed with water.
Intermittent wiping continues when all doors
are closed and:
R you shift the automatic transmission to
drive position D or reverse gear R
or
R you change the wipe setting on the
combination switch.
In the 0062 or 0063 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 0062 position, causing
the windshield wipers to wipe more
frequently. 114

WARNING
For safety reasons, switch off the wipers and
remove the SmartKey from

the starter switch
before replacing a wiper blade. Otherwise, the
wiper motor could suddenly turn on and cause
injury.
! 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/
rear window.
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.

automatic climate control.
R Activate climate control using
the 0058 and
0056 buttons. The indicator lamps in the
0058 and 0056 buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "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 ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side as well. The
indicator lamp in the 00D6 button goes out.120

WARNING
If you switch off the cooling function, the vehicle will not be cooled when weather conditions are
warm. The windows can
fog up more quickly. Window fogging may impair visibility and endanger
you and others.
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. 124
Operating the climate control systems
Climate control

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.
i
The cooling with air dehumidification function uses refrigerant R134a. This coolant does
not contain chlorofluorocarbons, and therefore does not damage the ozone layer.
Activating the cooling with air dehumidification function !
If the cooling with air dehumidification does not switch on, it is possible that the climate
control system has lost coolant.
Have the cooling with air dehumidification checked at a qualified specialist workshop. Canada only
