Auxiliary heating (additional
heating)*
Intr
oduction
The auxiliary heater runs on fuel from the ve-
hicle's tank and can be used while you are
driving and when the vehicle is st
ationary.
The auxiliary heater can be switched on using
the fast heating button of the air conditioning
controls, with the remote control or by previ-
ously programming a departure time in the
auxiliary heater menu of the infotainment sys-
tem.
In winter, with the auxiliary heater switched
on, you can defog the windscreen and leave
it free of ice and snow (if it is a thin layer) be-
fore you start driving.
If the outside temperature is very high, the ve-
hicle interior can be ventilated with the en-
gine off using the auxiliary heater.
WARNING
The auxiliary heater exhaust fumes contain
carbon monoxide, an odourless and colour-
less t
oxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death.

Never switch on the auxiliary heater or
leave it running in enclosed spaces or
areas with no ventilation.

Never programme the auxiliary heater so
that it swit
ches itself on and is running in an
enclosed space or an area with no ventila-
tion.
WARNING
The components of the auxiliary heater are
e
xtremely hot and could cause a fire.

of the exhaust system can come in contact
with easily flammable materials that might
be below the vehicle, such as dried grass.

Never place food, medicines or other tem-
perature-sensitive objects close t
o the air
vents. Food, medicines and other objects
