Replacing the wiper blades
Important safety notes
GWARNING
If the windshieldw ipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is arisk of
injury.
Always switch off the windshieldw ipers and
ignition before changing the wiper blades.
!Never open the hood/tailgate or rear doors
if aw indshieldw iper arm has been folded
awayf rom the windshield/rear window.
Never fold awindshieldw iper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshieldw iper arm firmly when
you change the wiper blade.Ify ou release the
windshieldw iper arm without awiper 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 bladesc hanged ataqualified spe-
cialist workshop.
!Only hold the wiper blade by the wiper arm.
You could otherwise damage the wiper rub-
ber.
Wiper bladesa re wear parts. The windshieldw ill
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 bladesoft he windshield
wiper.
Service indicator
Replacement wiper bladesf or the windshield
wiper have aservice 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
(

Overview of climat econtrol systems
Important safetyn otes
Observethe recommende dsettings on the fol-
lowing pages. Otherwise, the windows could fog
up.
To preventt he windows from foggingu p:
Ronly switchoff climatec ontrolbriefly
Ronly switc honair-recirculation mode briefly
Rfor vehicles with TEMPMATIC air-conditioning
or automatic climatec ontrol, switchonthe
"Cooling with air dehumidification "function.
Rfor vehicles with automatic climatec ontrol,

Climate contro lregulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Climate contro lisonly operational when the
engin eisrunning. The system only functions
optimally when the side windows are closed.
Ventilate the vehicle for abrief period during
warm weather. In order to cool the vehicle more
rapidly, switc hclimat econtro ltoair-recircula-
tion mode briefly. This will speed up the cooling
process and the desired interior temperature
will be reached more quickly.
The integrated filter can filter out most particles
of dust and completely filter sout pollen. In vehi-
cles with automatic climatec ontrol, gaseous
pollutant sand odors will also be reduced. A
clogged filter reduces the airflow int othe vehi-
cle interior. For this reason,y ou should always
observet he interval for replacin gthe filter,
which is specified in the Maintenance Booklet.
As the interval between changes depends on
environmental conditions, e.g. heavy air pollu- tion
,the interval may be shorter than stated in
the Maintenance Booklet.

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
the 0 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 function can only be
switched on or off whilet he ignition is
switched off. The indicator lamp in the Ì
button comes on when the function is
switched on.
Approximatel y60minutes after parking the
vehicle,a utomatic climate control can switch on
automatically ,depending on the outsid etem-
perature. The vehicle is then ventilated for about
30 minutes at low fan setting and the automatic
climate control system is dried out.
During automatic engine switch-off, the climate control system only operates at areduced capa-
city. Further information on the automatic
engine switch-off can be found under "ECO
start/stop function" (
Ypage 122).
Information on rear-compartment air
conditioning
Vehicles with TEMPMATIC air-conditioning
system
Switch the rear-compartment air-conditioning
system on and off using the TEMPMATIC air-
conditioning system control panel. When you
switch on the rear-compartment heating, the
settings for temperature ,airflow and air distri-
bution are automatically adopted on the control
panel for the rear-compartment heating.
The indicator lamp in the /button comes on
when the rear-compartment air-conditioning is
switched on (
Ypage 108).
Vehicles with automatic climate control
To operate the rear-compartment air condition-
ing, use the control panel of the automatic cli-
mate 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 automati-
cally adopted for the rear-compartment air con-
ditioning. When automatic climate control is in
à automatic mode, the air distribution of the
rear-compartment air conditioning is also auto-
matically adjusted. When you set the temperature and airflow of the
rear-compartment air conditioning, the indica-
tor lamp of the
/button (
Ypage 109)
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.

Important safety notes
When the climate control is switched off, air
intake and air circulation also stop. Only use this
setting for abrief period.O therwise,the win-
dows could fog up.
