iCanada only:
If the wind shield wiper s areswitched on and
you stop the veh icle, the windshield wiper
speed isreduced. For example, ifyou have
selected level IIand stop the veh icle,wipin g
continues with intermittent wipe whilethe
veh icle is stationary. Ifintermittent wipe is
selected, the intervals become longer.
Vehicles with a rain and light sensor: you
can use level Ias the universal setting. The
rain and light sensor sets the appropriate wip-
ing frequency automatically, according to the
intensity of the rain. When you stop the veh i-
cle, leve lsIII and IIare swit ched down to
level Iautomatically.
The wind shield wiper will return to the original
level when you drive faster than 5 mph
(8 km/h).
You can adjust the sensitivit y of the rain and
light sensor using the on-board computer
(
Ypage 170).
In formation on checking the washer fluid level
can befound inthe "Maintenance and care"
section (

Replacing the wiper blades
GWARNING
If the wind shield wipers begin to move while
you are changing the wiperblades, you could
be trapped by the wiper arm. There isa risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper armwithout a
wiper blade back onto the windshield/rear
wind ow.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiperblade
and itfalls onto the windshield, the windshield
may be damaged by the force of the impact.
We recommend that you have the wiper
blades replaced at a qualified specialist work-
shop.
!Only hold the wiperblade by the wiperarm.
You could otherwise damage the wiper rub-
ber.
The wind shield will no longerbe wipedproperly
if the wiper blades are worn. Replace the wiper
blades twice a year, ideally in spring and fall.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 27).
Overview of climate control systems
Important safety notes
Observe the recommended settings on the fol-
lowing pages. Otherwise, the windows could fog
up.
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
iVentilate the vehicle for a brief period during
warm weather. In order to cool the vehicle
more rapidly, switch climate control to air-
recirculation mode briefly. This will speed up
the cooling process and the desired interior
temperature will be reached more quickly.
iThe integrated filter can filter out most par-
ticles of dust and completely filters out pollen.
A clogged filter reduces the airflow into the
vehicle interior. For this reason, you should
always observe the interval for replacing the
filter, which is specified in the Maintenance
Booklet. As it depends on environmental con-
ditions, e.g. heavy air pollution, the interval
may be shorter than that stated in the Main-
tenance Booklet.

RSet the temperature control to the middle
level. Only change the temperature in small
increments.
If you wish to heat up the vehicle interior as
quickly as possible, set the temperature con-
trol to thezmaximum setting. When the
desired interior temperature has been reached, turn the temperature control back
down in small steps.
ROnly use the settings for defrosting the wind-
shield 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
as no fresh air is drawn into the vehicle in air-
recirculation mode. The indicator lamp in the
h button comes on when the function is
switched on.

Important information
If you switch off the "Cooling with air dehumid-
ification" function, the air inside the vehicle will
not be cooled (in warm weather) or dehumidi-
fied. The windows could fog up more quickly.
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 appear on the underside of
the vehicle when in cooling mode. This is normal
and not a sign that there is a malfunction.
