Problems with the seat heating
Problem
Possible causes/consequences and
0050
0050Solutions The seat heating has
switched off prema-
turely or cannot be
switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off electrical consumers that you do not need, such as
the rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating will
switch back on automatically. Steering wheel

WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,

R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. G
WARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder. X
Turn the SmartKey to position 1or 2in the
ignition lock (Y page 143).
X Press button 0043for the left-hand exterior
mirror or button 0044for the right-hand exte-
rior mirror.
The indicator lamp in the corresponding
button lights up in red.
The indicator lamp goes out again after
some time. You can adjust the selected
mirror using adjustment button 0087as long
as the indicator lamp is lit.
X Press adjustment button 0087up, down, or to
the left or right until you have adjusted the
exterior mirror to the correct position. You
should have a good overview of traffic con- ditions.
The convex exterior mirrors provide a larger
field of vision.
After the engine has been started, the exte-
rior mirrors are automatically heated at low
outside temperatures. Heating takes a maxi-
mum of ten minutes.
i You can also heat up the exterior mirrors
manually by switching on the rear window
defroster.

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.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open the hood/tailgate if a wiper
arm has been folded away from the wind-
shield/rear window. Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear window.
Hold the windshield wiper arm firmly whenyou change the wiper blade. If you release
the 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
specialist workshop.

Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific 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.
i Read the information on qualified special-
ist workshops (Y page 28). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the defrost windshield function
briefly, if required
The air-conditioning system/dual-zone auto-
matic climate control regulates the tempera- ture and the humidity of the vehicle interior
and filters out undesirable substances from
the air.
The air-conditioning system/dual-zone auto-
matic climate control can only be operated
when the engine is running. Optimum opera-
tion is only achieved with the side windows
and panorama roof with power tilt/sliding
panel closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 137).
Always keep the ventilation flaps behind the
side trim panel in the cargo compartment clear (Y
page 119). Otherwise the vehicle will
not be ventilated correctly.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 88). This
will speed up the cooling process and the
desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol- lutants and odors. A clogged filter reduces
the amount of air supplied to the vehicle
interior. For this reason, 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 pollution, the
interval may be shorter than stated in the
Maintenance Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour after the SmartKey has been removed in
order to dry the air-conditioning system.
The vehicle is then ventilated for
30 minutes. 126

system
Air-conditioning system Below, you can find a number of notes and
recommendations to help you use the air-
conditioning system optimally.
R Switch on the air-conditioning system by
turning control knob 0083clockwise to the
desired position (except position 0).
R Set the temperature to 72 ‡ (22 †).
R Recommendation for avoiding misted
windows at low exterior temperatures
or in rain: switch on the 005Acooling with
dehumidification function (Y page 131).
Set air distribution to 0061and if possible
switch off 009Cand009B (Ypage 134).
In air-recirculation mode, switch 008Aoff
(Y page 137).
Set airflow control 0083to a setting between
3 and 6(Y page 134).
R Recommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control 0083to a setting between 3
and 6(Y page 134).
R Recommendation for a constant vehi-
cle interior temperature: set airflow con-
trol 0083to a setting between 1and 3
(Y page 134).
R Recommendation for air distribution in
the winter: set009B and0061
(Y page 134).
Recommendation for air distribution in
the summer: set009C or009C and0061
(Y page 134).
R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again. R
Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Vehicles with COMAND: if you change the
settings of the climate control system, the
climate status display appears for three
seconds at the bottom of the screen in the
COMAND display. See also the separate
COMAND operating instructions. You will
see the current settings of the various cli-
mate control functions.
ECO start/stop function During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require the full cli-
mate control output, you can switch off the
ECO start/stop function by pressing the ECO
button (Y page 146). 128
