Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops (Y page 29). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and air humidity in the vehicle interior. The air filter cleans the air, thus improving the inte-
rior climate.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. Optimum climate control is only ach-
ieved with the side windows and roof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 177).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 107).
This will speed up the cooling process and the desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol- lutants and odors. A clogged 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 Maintenance
Booklet. As it depends on environmental
conditions, e.g. heavy air pollution, the
interval may be shorter than stated in the
Maintenance Booklet.
i It is possible that the blower may be acti-
vated automatically 60 minutes after the
SmartKey has been removed depending on various factors, e.g. the outside tempera-
ture. The vehicle is then ventilated for
30 minutes to dry the climate control sys-
tem. 164
Overview of climate control systemsClimate control

In overrun mode, kinetic energy is converted
by means of energy recuperation into electri- cal energy and stored in the high-voltage bat-
tery.
The high-voltage battery can be charged as
follows:
R through energy recuperation while the
vehicle is in motion
R during the journey using the CHARGE mode
R with the relevant charging cable at an elec-
trical outlet while the vehicle is stationary
R with the relevant charging cable at a wall-
box while the vehicle is stationary
R with the relevant charging cable at a charg-
ing station while the vehicle is stationary
The high-voltage battery can be charged in a
nominal voltage range from 100 V to 240 V.
High and low outside temperatures Low outside temperatures
At very low outside temperatures the maxi-
mum power output of the high-voltage battery
may be reduced. The high-voltage battery is
then no longer able to provide the normal
electrical power output.
High outside temperatures
To prevent damage to the high-voltage bat-
tery due to very high outside temperatures,
the maximum power output of the high-volt-
age 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 the use of air conditioning or heating
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 in
temperatures that are too high or too low over
a long period (e.g. container transport).
If you park the vehicle and leave it stationaryfor longer periods, connect it to a power sup-
ply.
Conditions of use Please note the information on exceptions
and limitations in warranty documentation
and in the Maintenance Booklet.
Handling the charging cable and charg- ing cable controls Do not leave the charging cable controls
(Y
page 213) hanging loose from an electrical
outlet. Otherwise, this could result in a poor
contact with the electrical outlet and mal-
functions when charging the vehicle.
To ensure that the cable on the controls of the charging cable is not subjected to incorrect
loads, observe the following:
R Never lift the controls up at the charging
cable connector or the power supply plug.
R Do not carry the controls by the connector.
Heat generated by the charging cable
and connector Pay attention to the "Important safety notes"
(Y page 209).
During the charging process, the charging
cable and connector may heat up. Charging the high-voltage battery (plug-in hybrid vehicles)
