Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: (Y page 25). Overview of climate control systems
Important safety notes

WARNING
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally if the side windows and the roof are
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 150).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 96). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged 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 Service Booklet
.As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30minutes to dry
the air-conditioning system. 142

engine has been switched off. The heating
time depends on the temperature that has
been set for the vehicle interior.
X To activate: press theÌbutton.
The indicator lamp above the Ìbutton
lights up.
i The blower will run at a low speed regard-
less 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 To deactivate: press theÌbutton.
The indicator lamp above the Ìbutton
goes out.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30minutes to dry
the air-conditioning system.
Residual heat is deactivated automatically:
R after approximately 30 minutes
R when the ignition is switched on
R if the battery voltage drops Auxiliary heating
Important safety notes G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation .Inhaling these
exhaus tfumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g .agarage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels. The material could otherwise ignite and set
the vehicle alight. Choose your parking spot
accordingly.
Operating the auxiliary heating is thus pro-
hibited at filling stations or when your vehicle
is being refuelled. You must therefore switch
off the auxiliary heating at filling stations.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the
passenger compartment to the selected tem-
perature. It does not use the heat of the run-
ning engine to do this. The auxiliary heating
is operated directly using the vehicle's fuel.
For this reason, the tank content must be at
least at reserve fuel level to ensure that the
auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
The auxiliary heating switches off automati-
cally after 50 minutes. This time limit can be
altered. To do this, visit a qualified specialist
workshop.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before switching on X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when climate control is set to
manual. Optimum comfort can be attained Operating the climate control system

Indicator lamp ;lights up. If drive pro-
gram S,S+ orMis active, the automatic
transmission switches to drive program C.
If all conditions for automatic engine
switch-off (Y page 166) are fulfilled, the
¤ symbol is shown in green in the mul-
tifunction display. In addition, the Stop/Start active message is shown in the
AMG menu in the multifunction display.
If conditions for automatic engine switch-
off have not been fulfilled, the (Y page 166)
¤ symbol will be shown in yellow. If this
is the case, the ECO start/stop function is
not available. In addition, the Stop/Startinactive message is shown in the AMG
menu in the multifunction display.
i If indicator lamp ;is off, the ECO start/
stop function has been deactivated man-
ually or as the result of a malfunction. The
engine will then not be switched off auto-
matically when the vehicle stops.
i Every time you switch on the engine using
the key or the Start/Stop button, the ECO
start/stop function is activated.
Automatic engine switch-off Method of operation
The ECO start/stop function is operational
and the
¤symbol is displayed in green in
the multifunction display, if:
R the indicator lamp in the ECO button is lit
green.
R the vehicle is stationary.
R the outside temperature is within the com-
fort range.
R the engine is at normal operating temper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently charged. R
the system detects that the windscreen is
not misted up when the air-conditioning
system is switched on.
R the bonnet is closed.
R the driver's door is closed and the driver's
seat belt is fastened.
If conditions for automatic engine switch-off
have not been fulfilled, the ¤symbol will
be shown in yellow.
AMG vehicles: the AMG menu in the multi-
function display additionally shows the Stop/ Start inactive message.
i If you shift the transmission from Rto D,
the ECO start/stop function is available
again once the ¤symbol reappears in
green in the multifunction display.
i All vehicles (apart from AMG vehi-
cles): Automatic engine switch-off can
take place a maximum of four times con-
secutively (initial stop then repeated three
times). The ¤symbol is shown in yellow
in the multifunction display after the engine
has been started automatically for the
fourth time. The automatic engine stop is
available again once when the ¤symbol
is shown in green in the multifunction dis-
play.
i AMG vehicles: times which the engine
can be automatically switched off.
i During automatic engine switch-off, the
climate control system only operates at a
reduced capacity. If you require full climate
control capacity, the ECO start/stop func-
tion can be deactivated by pressing the
ECO button (Y page 165).166

Vehicles with manual transmission
The ECO start/stop function switches off the
engine automatically at low speeds.

still.
X Engage neutral N(Ypage 170) (follow
gearshift instruction :to engage neutral
N, if necessary).
X Release the clutch pedal.
The engine is switched off automatically.
Vehicles with automatic transmission
If the vehicle is braked to a standstill in trans-
mission position Dor Nand the brake
remains depressed, the ECO start/stop func-
tion switches off the engine automatically.
i You can also activate the HOLD function

has been switched off automatically. It is
then not necessary to continue applying
the brakes during the automatic stop
phase. Whe nyou depress the accelerator
pedal, the engine starts automatically and
the braking effect of the HOLD function is
deactivated. Depress the accelerator pedal
gently, as the engine must be started first.
