General information about the
additional heater
In cold climate zones
1
an additional heater may
be required to obtain the correct operating
temperature in the engine and to obtain suffi-
cient heating in the passenger compartment.
Fuel-driven additional heater
A fuel-driven additional heater is fitted in cars
with diesel engines.
The heater starts automatically when extra
heat is required when the engine is running.
The heater is switched off automatically when
the correct temperature is reached or when the
engine is switched off.
NOTE
When the additional heater is active there
may be smoke from the right-hand wheel
housing which is perfectly normal.
Auto mode or shutdown
The additional heater's automatic start
sequence can be switched off if required.

Passenger compartment heater*

Electric additional heater
Cars with certain petrol engines

have an elec-
tric additional heater integrated into the car's
climate control system.
In a semi-cold
1
climate zone diesel-driven cars
have an electric additional heater instead of a
fuel-driven version.
The heater cannot be controlled manually but
is instead activated automatically after the
engine has been started in outside tempera-
tures below 14 °C and is switched off after the
set passenger compartment temperature has
been reached.
