the air dehumidification function
Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
G
WARNING
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions
are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.
You can activate or deactivate the cooling
with air dehumidification function via
COMAND (Y page 267).
i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer. Problems with the cooling with air
dehumidification function If you can no longer switch on the cooling with
air dehumidification function via COMAND,
the

cooling with air dehumidification function
is switched off due to a malfunction.
X Consult a qualified specialist workshop. Setting climate control to automatic
G
WARNING
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions

are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If desired, cooling with air
dehumidification can be deactivated.

Activating/deactivating the residual
heat function
It
is possible to make use of the residual heat
of the engine to continue heating the
stationary vehicle for up to 30 minutes after
the engine has been switched off. The heating
time depends on the temperature that has
been set.
i The blower will run at a low speed
regardless of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
X Turn the SmartKey to position 0 in the
ignition lock or remove it.
X To activate: press the Ì rocker switch
up or down.
The indicator lamp in the Ì rocker
switch lights up.
X To deactivate: press the Ì rocker
switch up or down.

switch goes out.
i Residual heat is deactivated
automatically:
R after about 30 minutes
R when the ignition is switched on
R if the battery voltage drops
R if the coolant temperature is too low Setting the air vents
Important safety notes
G
WARNING
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold

(depending on the set temperature). This
could cause burns or frostbite to unprotected
skin in the immediate area of the air vents. Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment

to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air intake grille on the hood free
of blockages, such as ice, snow or leaves
R never cover the air vents or air intake grille
in the vehicle interior.
i For virtually draft-free ventilation, adjust
the sliders of the air vents to the center
position. Setting the center air vents

Problem Possible causes/consequences and
M SolutionsVehicles with a
gasoline engine:
The engine is not
running smoothly and
is misfiring. There is a malfunction in the engine electronics or a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz Center.
Otherwise, non-combusted fuel may get into the catalytic
converter and damage it. The coolant
temperature gauge
shows a value above
248 ‡
(120 †). The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 460). Observe the warning
notes as you do so and add coolant if necessary. Automatic transmission
Important safety notes
G
WARNING
It is dangerous to shift the automatic
transmission out of parking position P or
neutral position N if the engine speed is
higher

than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal. G
WARNING
Keep in mind that turning off the engine alone
only
will shift the automatic transmission into
neutral position N automatically.
Always shift the automatic transmission into
park position P before turning off the engine.
Otherwise the vehicle could roll away which
could result in an accident and/or serious
personal injury. G
WARNING
HYBRID vehicles: It is imperative that you read
the HYBRID Supplemental Operating
Instructions

included in your vehicle literature
portfolio. You may otherwise not receive all
necessary safety information and warning for
the operation of your vehicle. DIRECT SELECT lever

cause
some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the 372

vehicle and do not stand near the vehicle until
the engine has cooled down.
The coolant temperature gauge is in the
instrument cluster on the left-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant
temperature may rise to 248 ‡ (120 †).
! If the coolant temperature is too high a
display message is shown.
If the coolant temperature rises above
248
‡(120 †), do not drive any further as
this could damage the engine. Tachometer
The
red band in the tachometer indicates the
engine's overrevving range.
! Do not drive in the overrevving range, as
this could damage the engine.
The fuel supply is interrupted to protect the
engine when the red band is reached. Outside temperature display
The outside temperature display is in the
multifunction display

(Y page 374). G
WARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing

point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
Changes in the outside temperature are
displayed after a short delay. Operating the on-board computer
The on-board computer is activated as soon
as

you turn the SmartKey to position 2 in the
ignition lock. You can control the multifunction display and
