Windshield wipers
Switching the windshield wipers
on/off
!
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 scratch the glass
if wiping takes place when the windshield 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 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.

Notes on using the air-conditioning
system
Air-conditioning system
Below, you can find a number of notes and rec-
ommendations to help you use the air-condi-
tioning system optimally.
RSwitch on the air-conditioning system by turn- ing control knob Aclockwise to the desired
position (except position 0).
RSet the temperature to 72 ‡ (22 †).
RRecommendation for avoiding misted
windows at low exterior temperatures or
in rain: switch on the ¿cooling with dehu-
midification function (
Ypage 117).
Set air distribution to ¯and if possible
switch off PandO (
Ypage 118).
Deactivate air-recirculation mode e
(
Ypage 121).
Set airflow control Ato a setting between 3
and 6(
Ypage 119).
RRecommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3and
6 (
Ypage 119).
RRecommendation for a constant vehicle
interior temperature: set airflow controlA
to a setting between 1and 3(
Ypage 119).
RRecommendation for air distribution in
winter: select the Oand¯ settings
(
Ypage 118).
Recommendation for air distribution in
summer: select the PorP and¯
settings (
Ypage 118).
ROnly use the "Windshield defrosting" function
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 tu
nnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
RIf you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen on the multimedia
system display; see Digital Operator's Man-
