Important safety notes
G
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. Windshield wipers

Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and

more quickly. Window fogging may impair
visibility and endanger you and others.
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/deactivating !
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.
