standstill
The hazard warning lamps switch on automati-
cally if an air bag or the Emergency Tensioning
Devices are triggered and the SmartKey is in
position 1in the ignition lock.
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
6 mph (10 km/h) again after a full brake appli-
cation.
iThe hazard warning lamps still operate if the
ignition is switched off.
Headlamps and indicator lamps fog-
ged up on the inside
The headlamps and the indicator lamps in the
exterior mirrors may fog up on the inside if there
is high atmospheric humidity.
XDrive with the headlamps switched on.
The level of moisture diminishes, depending
on the length of the journey and the weather
conditions (humidity and temperature).
If the level of moisture does not diminish:
XHave the headlamps checked at a qualified
specialist workshop.

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.
!To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
wiper.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.

Z
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, the windshield
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.

Useful information
i
This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific differences are possible. Please note
that your vehicle may not be equipped with all
features described. This also applies to
safety-related systems and functions.

workshops: (Ypage 23).
Overview of climate control systems
Important safety notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up. This could prevent you from observing the
traffic conditions, thereby causing an accident.
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Dual-zone automatic climate control is only
operational when the engine is running. Opti-
mum operation is only achieved if you drive with
the side windows and sliding sunroof closed.
The climatic comfort deteriorates whilst the slid-
ing sunroof is open. The automatic climate con-
trol cannot maintain the set temperature with
the sliding sunroof open. You have to adjust the
climate control manually.
iThe residual heat function can only be acti-
vated or deactivated with the ignition
switched off (
Ypage 108).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 68). This will speed
up the cooling process and the desired vehi-
cle interior temperature will be reached more
quickly.
iThe integrated filter can filter out most par-
ticles of dust, and completely filters out pol-
len. A clogged filter reduces the amount of air
supplied to the vehicle interior. For this rea-
son, you should always observe the interval
for replacing the filter, which is specified in
the Maintenance Booklet. As it depends on
environmental conditions, e.g. heavy air pol- lution, the interval may be shorter than stated
in the Maintenance Booklet.

GWARNING
If you switch off the cooling function, the vehi- cle will not be cooled when weather condi-
tions are warm. The windows can fog up more
quickly. Window fogging may impair visibility

In automatic mode, the set temperature is main-
tained at a constant level. The system automat-
ically regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode will achieve optimal operation
if cooling with air dehumidification is also acti-
vated. If desired, cooling with air dehumidifica-
tion can be deactivated.
