Switching the windshield wiper
on/off
! 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 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 residues 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 becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the wind-
shield.
For this reason, you should always switch
off the windshield wipers in dry weather. 1

X Turn the í wiper switch to the corre-
sponding position.
In the Ä or Å
positions, the appropriate
wiping frequency is set automatically accord-
ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive to
precipitation than in the Ä position, caus-
ing the windshield wipers to wipe more fre-
quently.
The windshield will no longer be wiped prop-
erly if the wiper blades are worn. This may pre-
vent you from observing the traffic conditions.

another five seconds. The rear window
wiper then wipes according to the original
position 2 or 3.
The rear window wiper switches on automati-
cally if you engage reverse gear and the wind-
shield wipers are on.
If the vehicle is stationary and you open the
tailgate or rear-end door, the rear window
wiper will stop automatically. The rear window
wiper will only resume wiping again when the
tailgate and rear-end door are closed and you
pull away again.
The rear window will no longer be wiped prop-
erly if the wiper blade is worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blade can be found under "Replacing wiper blades"

Important safety notes 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/tailgate or rear
doors if a windshield wiper arm has been
folded away from the windshield/rear win-
dow.
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/rear
window, the windshield/rear window may
be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! Only hold the wiper blade by the wiper
arm. You could otherwise damage the wiper
rubber.
Wiper blades are wear parts. The windshield
will no longer be wiped properly if the wiper
blades are worn. This may prevent you from
observing the traffic conditions.
Please observe the service indicator after
changing the wiper blades of the windshield
wiper.
Service indicator Replacement wiper blades for the windshield
wiper have a service indicator on the tip of the
wiper blade.
Depending on the amount of use, the service
indicator will change color from black to yel-
low.110

If you wish to use the driver's side settings
on the co-driver's side and, for vehicles with
rear-compartment air conditioning, for the
rear compartment as well, use the "Synchro-
nization" function. The indicator lamp in the
0 button comes on when the function is
switched on.
R After long journeys, you can use the residual
heat of the engine to heat the stationary
vehicle. The residual heat utilization can
only be switched on or off while the ignition
is switched off. The indicator lamp in the
Ì button comes on when the function is
switched on.
Approximately 60 minutes after parking the
vehicle, 3-zone automatic climate control can
switch on automatically, depending on the out-
side temperature. The vehicle is then ventila-
ted for about 30 minutes at low fan setting
and 3-zone automatic climate control is dried
out. Optimum use of the rear compart-
ment air conditioning
Vehicles with air-conditioning system
Switch the rear-compartment air-conditioning
system on and off using the air-conditioning
system control panel. When you switch on the
rear-compartment air conditioning, your set-
tings for temperature, airflow and air distribu-
tion are automatically adopted on the control
panel for the rear-compartment air condition-
ing.
The indicator lamp in the / button comes
on when the rear-compartment air-condition-
ing is switched on
(Y page 115).
Vehicles with dual-zone automatic climate
control
To operate the rear-compartment air condi-
tioning, use the control panel of the dual-zone
automatic climate control system. When you
switch on the rear-compartment air condition-
ing, you can set the temperature and airflow
separately on the control panel. The airflow
setting is automatically adopted for the rear-
compartment air conditioning. When dual-zone
automatic climate control is in à automatic
mode, the air distribution of the rear-compart-
ment air conditioning is also automatically
adjusted.
When you set the temperature and airflow of
the rear-compartment air conditioning, the indicator lamp of the / button
(Y page

116) flashes. When the rear-compart-
ment air conditioning is switched on, the indi-
cator lamp on the / button lights up.
For optimum climate control, set the tempera-
ture to 72 ‡ (22 †) and switch on à auto-
matic mode. Only change the temperature in
small increments. Operating the climate control sys-

Climate control

Regulating climate control automati-
cally
General notes When dual-zone automatic climate control is in
automatic mode, the set temperature is auto-
matically kept constant. The system automati-
cally regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode will achieve optimal operation
if the cooling with air dehumidification func-
tion is also activated. If desired, the cooling
with air dehumidification function can be deac-
tivated (
Y page 118).
Dual-zone automatic climate control Automatic mode for automatic climate control
settings can only be activated or deactivated
on the first menu level. If you do not set a new
value for the rear-compartment climate control
in the second menu level within approx. ten
seconds, the control panel display goes back
to the first menu level.
X Switch on climate control ( Y page 117).
X Set temperature for the driver's and front-
passenger side and, for vehicles with rear-
compartment air conditioning, for the rear
compartment, too

X To switch automatic mode on or off:
press the à button.
If the indicator lamp in the
à button
lights up, automatic mode is activated. The
airflow and air distribution are controlled
automatically and the windshield defrosting
function is deactivated.
If you deactivate automatic mode, the auto-
matic climate control system saves the current
settings.
In automatic mode, if you adjust the airflow or
air distribution manually, the indicator lamp
above the à button goes out. The function
which has not been changed manually, how-
ever, continues to be controlled automatically. Setting the temperature
