when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
!Make sure the bulbs are always securely
installed.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore make
sure that these function correctly at all times.

Lights and windshield wipers

Windshield wipers
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 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.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratch the windshield.
For this reason, you should always switch off
the windshield wipers in dry weather.

XTurn the key to position 1or 2in the ignition
lock.
XTurn the íwiper switch to the corre-
sponding position.
In the ÄorÅ positions, the appropriate
wiping frequency is set automatically according
to the intensity of the rain. In the Åposition,
the rain sensor is more sensitive to precipitation
than in the Äposition, causing the wind-
shield wipers to wipe more frequently.
The windshield will no longer be wiped properly
if the wiper blades are worn. This may prevent
you from observing the traffic conditions. Infor-
mation on replacing the wiper blades can be
found under "Replacing wiper blades"
(
Ypage 107).

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
(

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.
