G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a 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 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.
We recommend that you have the wiper
blades replaced at a qualified specialist
workshop.
! Only hold the wiper blade by the wiper
arm. You could otherwise damage the
wiper rubber.
The windshield will no longer be wiped prop-
erly if the wiper blades are worn. Replace the
wiper blades twice a year, ideally in spring and
fall. Front windshield wiper arm with wiper blade

lock.
X Remove the cause of the obstruction.
X Switch on the windshield wipers again. The windshield wiper
does not move at all. There is a malfunction in the windshield wiper drive.
X Select another wiper speed on the combination switch.
X Have the windshield wipers checked at a qualified specialist
workshop. The washer fluid com-
ing from the spray noz-
zles no longer hits the
center of the wind-
shield. The spray nozzles are misaligned.

R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again. R
Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
The center and side air vents are adjustable.
On vehicles with a rear-compartment air-con-
ditioning system, you can also adjust the air
vents in the roof duct.
i For virtually draft-free ventilation, adjust
the sliders of the center air vents to the
center position.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior, please observe the following notes:
R keep the air inlet grille on the hood free of
blockages, such as ice, snow or leaves.
R never cover the vents or the ventilation
grilles in the vehicle interior. 120
