XTo wipe with washer fluid: press theè
switch beyond the current position as far as it
will go to 1or press and hold 4.
When you release the èswitch, the rear
window wiper continues to wipe for about
another five seconds. The rear window wiper
then wipes according to the original position
2 or3.
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 tail-
gate or rear door, the rear window wiper will
stop automatically. The rear window wiper will
only resume wiping again when the tailgate and
rear door are closed and you pull away again.
The rear window will no longer be wiped properly if the wiper blade is worn. This may prevent you
from observing the traffic conditions. Informa-
tion on replacing the wiper blade can be found
under "Replacing wiper blades" (
Ypage 107).
Replacing the wiper blades
Important safety notes
GWARNING
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 window.
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 rub-
ber.
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 yellow.
Change the wiper blade if:
Rthe wiper blade is damaged
Rthe service indicator has turned yellow
In order to activate the service indicator, you
have to remove the protective film
(
Ypage 107).

RIf you wish to use the driver's side settings on
the front-passenger side and, for vehicles
with rear-compartment air conditioning, for
the rear compartment as well, use the "Syn-
chronization" function. The indicator lamp in
the0 button comes on when the function
is switched on.
RAfter long journeys, you can use the residual
heat of the engine to heat the stationary vehi-
cle. 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, dual-zone automatic climate control
can switch on automatically, depending on the
outside temperature. The vehicle is then venti-
lated for about 30 minutes at low fan setting and
dual-zone automatic climate control is dried out.
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. Further information on the automatic
engine switch-off can be found under "ECO
start/stop function" (
Ypage 125).
Optimum use of rear-compartment air
conditioning
Vehicles with air-conditioning system
Switch the rear-compartment air-conditioning
system on and off using the air-conditioning sys-
tem control panel. When you switch on the rear-
compartment air conditioning, your settings for
temperature, airflow and air distribution are
automatically adopted on the control panel for
the rear-compartment air conditioning.
The indicator lamp in the /button comes on
when the rear-compartment air-conditioning is
switched on (
Ypage 111).
Vehicles with dual-zone automatic climate
control
To operate the rear-compartment air condition-
ing, use the control panel of the dual-zone auto-
matic climate control system. When you switch
on the rear-compartment air conditioning, you
can set the temperature and airflow separately
on the control panel. The airflow setting is auto-
matically adopted for the rear-compartment air
conditioning. When dual-zone automatic cli-
mate control is in Ãautomatic mode, the air
distribution of the rear-compartment air condi-
tioning is also automatically adjusted. When you set the temperature and airflow of the
rear-compartment air conditioning, the indica-
tor lamp of the
/button (
Ypage 112)
flashes. When the rear-compartment air condi-
tioning is switched on, the indicator lamp on
the / button lights up.
For optimum climate control, set the tempera-
ture to 72 ‡ (22 †) and switch on Ãauto-
matic mode. Only change the temperature in
small increments.

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 function
is also activated. If desired, the cooling with air
dehumidification function can be deactivated
(
Ypage 114).
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.
XSwitch on climate control (Ypage 113).
XSet temperature for the driver's and front-
passenger side and, for vehicles with rear-
compartment air conditioning, for the rear
compartment, too (

XTo switch automatic mode on or off: press
the à button.
If the indicator lamp in the Ãbutton lights
up, automatic mode is activated. The airflow
and air distribution are controlled automati-
cally 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 Ãbutton goes out. The function
which has not been changed manually, however,
continues to be controlled automatically.

Dual-zone automatic climate control
You can set the temperature separately for the
driver's and front-passenger side. In vehicles
with rear-compartment air conditioning, the
temperature for the rear can be set additionally.
Each set temperature is automatically main-
tained at a constant level.
