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. Operating the climate control system
149Climate control
Z

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 left-hand side of the vehicle. The
emissions outlet is found behind the left front
wheel. ! Operating the auxiliary heating/ventilation
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 vehicle
interior to the set temperature. This occurs with- out using the heat of the running engine. 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 or auxiliary ventilation
automatically adjusts to changes in tempera-
ture and weather conditions. For this reason,
the auxiliary heating could switch from ventila-
tion mode to heating mode or from heating
mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventilation
switches off when you turn the key to position 2
(Y page 158).
The auxiliary heating 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. Before switching on X
Turn the key to position 2in the ignition lock
(Y page 158).
X Set the desired temperature.
The auxiliary heating/ventilation can be activa-
ted even when climate control is set to manual.
Optimum comfort can be attained when the sys-
tem is set to automatic mode. Set the temper-
ature to 22 †.
The auxiliary heating or auxiliary ventilation can
be switched on/off using the button on the
centre console or the remote control.
The on-board computer can be used to specify
up to three departure times, one of which may
be preselected (Y page 295).

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 grille on the bonnet and in
the engine compartment on the front- passenger side free of blockages, such as ice,
snow or leaves.
R never cover the vents or ventilation grilles in
the vehicle interior
i For virtually draught-free ventilation, adjust

the energy needed to operate the electric motor
and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
In overrun mode, kinetic energy is converted by
means of energy recuperation into electrical
energy and stored in the high-voltage battery.
Information on overrun mode (Y page 269).
The high-voltage battery can be charged as fol-
lows:
R through energy recuperation while the vehicle
is in motion
R during the journey by the combustion engine
in CHARGE operating mode (Y page 262)
R with the relevant charging cable at a mains
socket while the vehicle is stationary
R with the relevant charging cable at a wallbox
while the vehicle is stationary
R with the relevant charging cable at a charging
station while the vehicle is stationary
The high-voltage battery can be charged in a
nominal voltage range from 100 Vto 240 V.
You can view the charge status of the high-volt-
age battery in the multifunction display. You can
find information in "PLUG-IN HYBRID opera-
tion", section "Menus and submenus" under
"Energy flow display" (Y page 263).
High and low outside temperatures Low outside temperatures
The maximum performance of the high-voltage
battery is significantly reduced at very low out-
side temperatures. The high-voltage battery is
then no longer able to provide the normal elec-
trical power output.
High outside temperatures
To prevent damage to the high-voltage battery
due to very high outside temperatures, the max- imum power output of the high-voltage battery
is reduced by the vehicle.
Energy consumption and electrical
range The maximum electrical range is generally
reduced by:
R high and low outside temperatures
R operating the climate control system
R switching on consumers The battery's physical characteristics are such,
that leaving the vehicle parked for long periods
at low outdoor temperatures without charging it
can lead to:
R a reduction in battery performance
R longer charge times
Notes on battery care Avoid storing or transporting the vehicle at
excessively high or low temperatures over a long
period.
If you park the vehicle and leave it stationary for
long periods:
R check the charge status of the high-voltage
battery more often
R connect the vehicle to a power supply.
This prevents self-discharge and damage to the
high-voltage battery.
Terms of use Please note the information on exceptions and
limitations in the warranty documentation and
in the Service Booklet.
Handling the charging cable and charg- ing cable controls Do not leave the charging cable controls
(Y
page 185) hanging loose from a mains
socket. Otherwise, this could result in a poor
contact with the mains socket and malfunctions
when charging the vehicle.
To ensure that the brackets within the charging
cable controls are not subjected to incorrect
loads, observe the following:
R never lift or carry the controls by the charging
cable connector or the mains plug
R to transport the charging cable, the charging
cable can be:
- charging cable variant 1: wrapped around
the controls or secured to the control hous-
ing.
- charging cable variant 2: wrapped around
the controls and secured with a strap
Information on charging cable variants can be
found under "Charging cable for mains sockets"
(Y page 185). 184
