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 scratc ht he glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, alway su se
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 scratc ht he windshield.
For this reason, you should alway ss witch off
the windshield wipers in dry weather. Combination switch

Overview of climat ec ontrol systems
General notes Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To preven tt he windows from fogging up:R
switch off climate control only briefly R
switch on air-recirculation mode only briefly R
switch on the cooling with air dehumidifica-
tion function R
switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
Climate control can only be operated when the
engin eisr unning. Optimum operation is only
achieved with the side windows and roof closed. i When the weather is warm, ventilate the
vehicle for ab rief period. This will speed up
the cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. Ac logged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alway so bserve
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions ,e .g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book-
let.
