Operator’s Manual
Important notice for California retail
buyers and lessees of Mercedes-Benz automobiles
Under California law you may be entitled to
a replacement of your vehicle or a refund
of the purchase price or lease price, if
Mercedes-Benz USA, LLC and/or its au-
thorized repair or service facilities fail to fix
one or more substantial defects or mal-
functions in the vehicle that are covered by
its express warranty after a reasonable
number of repair attempts. During the pe-
riod of 18 months from original delivery of
the vehicle or the accumulation of
18 000 miles (approx. 29 000 km) on the
odometer of the vehicle, whichever occurs
first, a reasonable number of repair at-
tempts is presumed for a retail buyer or
lessee if one or more of the following oc-
curs: (1) the same substantial defect or mal-
function results in a condition that is
likely to cause death or serious bodily
injury if the vehicle is driven, that de-
fect or malfunction has been subject to
repair two or more times, and you have
directly notified Mercedes-Benz USA,
LLC in writing of the need for its repair,
(2) the same substantial defect or mal-
function of a less serious nature than
category (1) has been subject to repair
four or more times and you have direct-
ly notified us in writing of the need for
its repair, or(3) the vehicle is out of service by reason
of repair of the same or different sub-
stantial defects or malfunctions for a
cumulative total of more than
30 calender days.
Written notification should be sent to us,
not a dealer, at Mercedes-Benz USA, LLC,
Customer Assistance Center,
One Mercedes Drive, Montvale,

185 Controls in detail
Automatic climate control
Automatic climate control
The automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the ± mode is selected
(
page 195).
Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burn or frostbite on unprotected skin
in the immediate area of the air vents. Al-
ways keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary, change the air flow
using the air distribution controls to direct
the air away from the footwell air vents
(page 189).
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iThe current climate control settings
(ON/OFF, temperature, air volume, ac-
tivated charcoal filter, etc.) are stored
for each SmartKey before it is removed
from the starter switch or when the ve-
hicle is locked using the SmartKey with
KEYLESS-GO* (
page 122).
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow, leaves, sticks,
and any other debris.
Do not obstruct air volume by placing
objects on the air volume-through ex-
haust slots below the rear window.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.

fogging.iIf you keep button, pressed, the
side windows and the sliding / pop-up
roof will close.
Warning!
G
Never operate the side windows and the
tilt/sliding sunroof if there is the possibility
of anyone being harmed by the closing pro-
cedure.

dows can be immediately halted by
releasing the, button or by pressing the
respective window switch. The closing of the
tilt/sliding sunroof can be immediately halt-
ed by releasing the, button or by mov-
ing the tilt/sliding sunroof switch in the
overhead control panel in any direction.
iThe air recirculation mode is activated
automatically:

at high outside temperatures


if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases beyond a
predetermined level, for example in
a tunnel.
Please note that the charcoal filter
must be activated (
page 193) for the
air recirculation mode to be activated
automatically.
If you have turned off the air condition-
ing (
page 195) or the outside
temperature is below 41°F (5°C), the
air recirculation mode will not switch
on automatically.

193 Controls in detail

automatically:

after five minutes if the outside temper-
ature is below approximately 41°F
(5°C)


after five minutes if the air conditioning
is turned off


after 30 minutes if the outside temper-
ature is above approximately 41°F
(5°C)
At outside temperatures above 79°F
(26°C) the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.

duces bad odors and removes pollutants
from air entering the passenger compart-
ment.

M, P, U, a temperature con-
trol switch (
page 188) or air volume
switch 9 on the climate control pan-
el.
Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the automatic
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.

The indicator lamp on the button±
goes out.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
!If the± button on the automatic cli-
mate control panel starts to flash, this
indicates that the air conditioning is
losing refrigerant. The compressor has
turned itself off. The air conditioning
cannot be turned on again.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.

196 Controls in detailAutomatic climate controlResidual heat and ventilation
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.
Activating
Turn the SmartKey in the starter switch
to position1 or0, or remove it from
the starter switch.

Press buttonT (
page 188).
The indicator lamp on buttonT
comes on.Deactivating

Press buttonT (
page 188).
The indicator lamp on buttonT
goes out.
The residual heat is automatically turned
off:


when the ignition is switched on


after about 30 minutes


if the battery voltage drops
Ventilated storage compartment
Depending on vehicle model and configu-
ration, your vehicle is equipped with a stor-
age compartment under the front armrest
(page 234) which can be ventilated
when the automatic air conditioning is
switched on. If so equipped, the switch is
located inside the storage compartment in
the front. The air temperature is about the
same as that of the center air vents.
The air volume is dependent on the setting
of:


Air distribution control


Air volume control


Air vents in the dashboard
The air temperature is about the same as
that of the dashboard air vents. It cannot
be regulated separately.
iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at speed
setting1 regardless of the air
distribution control setting.

222 Controls in detailDriving systemsVehicle level control
Your vehicle automatically adjusts its ride
height to

reduce fuel consumption


increase vehicle safety
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:


With increasing speed, ride height is re-
duced by up to approximately 0.95 in
(24 mm).


With decreasing speed, the ride height
is again raised to the selected vehicle
level.Select the level 1 and 2 settings only when
required by current driving conditions.
Otherwise


Fuel consumption may increase


Handling may be impairediThese height adjustments are so small
that you may not notice any change.Warning!
G
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when low-
ering the vehicle chassis.
