Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire. When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
The auxiliary heating is fitted under the front
wing on the right-hand side of the vehicle. The emissions outlet is found behind the front
wheel on the right-hand side of the vehicle.
! 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.
Switch the auxiliary heating on regularly once a month for about ten minutes.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature. This
occurs without using the heat of the running
engine. The auxiliary heating is operated
directly using the vehicle's fuel. For this rea-
son, the tank content must be at least at
reserve fuel level to ensure that the auxiliary
heating functions.
The auxiliary heating or auxiliary ventilation
automatically adjusts to changes in temper-
ature and weather conditions. For this rea-
son, the auxiliary heating could switch from
ventilation mode to heating mode or from
heating mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventila-
tion is not active if the engine is running.
The auxiliary heating or auxiliary ventilation
switches off automatically 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. 178
Operating the climate control systemClimate control

Switching the auxiliary heating/venti-
lation on or off using the remote control
General notes
Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For more information, pleasecontact a qualified specialist workshop.
Store the remote control for the auxiliary
heating so that the auxiliary heating cannot
be switched on unintentionally. In particular,
ensure that the remote control for the auxili-
ary heating is kept out of the reach of chil-
dren.
The remote control has a range of approx-
imately 300 metres. This range is reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
If the remote control battery is low, the bat-
tery symbol on the left of the display is shown as empty. Replace the remote control battery and observe the important safety notes when
doing so (Y page 181).

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. 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 inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves
R never cover the vents or ventilation grilles
in the vehicle interior Adjusting the air vents
183Climate control Z

The internal combustion engine will not be
switched off automatically, if:
R the self-diagnosis function of the engine
control unit is still active
R there is a malfunction in the hybrid drive
system
R the climate control of the vehicle requires it
R the high-voltage battery is being charged
(Y page 292)
R automatic emissions tests are running
Automatic engine start
The internal combustion engine, which has
been automatically switched-off, starts auto-
matically in certain situations, when:
R the power demand from the driver via the
accelerator pedal is greater than the elec-
tric motor alone can provide
R the driver switches to drive program Sor M
R the charge level of the high-voltage battery
has reached the lower limit
R the settings of the automatic climate con-
trol require it, e.g. at external temperatures
above 30 †
Overrun mode
In overrun mode, the combustion engine is
switched off and is disconnected from the
drive train. The electric motor:
R generates low thrust, which corresponds to
the overrun mode of an active combustion
engine
R functions as an alternator and produces the
necessary energy for the auxiliary consum- ers and charges the high-voltage battery
Overrun mode is available in drive program E
below 160 km/h.
In drive program E, after the accelerator pedal
has been released the coasting characteris-
tics of the vehicle are adapted to the traffic
conditions. Further information about the
haptic accelerator pedal (Y page 297).Route-based energy management For route-based energy management, the
system factors in information about the
expected route when route guidance is
active.
The information on the route is provided by
COMAND Online and includes the following:
R road categories
R speed limitations
R data on downhill gradients
The use of electric energy is automatically
optimally distributed from the beginning to
the end of the journey, using information
about the route. The distribution is pre-emp-
tive and takes into consideration:
R the sections of the journey ahead
R the energy consumption on the whole route
The charge status of the high-voltage battery
is thus systematically controlled. In addition,
the control function takes into account that:
R the fuel savings through the use of electri-
cal energy can vary, depending on the route
(e.g. urban, interurban or motorway)
R the use of electrical energy is held available
in particular for electric operation (e.g.
urban routes)
The vehicle thus automatically selects the
optimum driving mode for the respective sec- tion of the route.
Route-based energy management is available
under the following conditions:
R drive program Eis selected
R HYBRID driving mode is selected
R active route guidance is activated
R suitable map data is available
When route-based energy management is in
operation, the area in front of the vehicle is
shown as green in the multifunction display. PLUG‑IN HYBRID operation
