all vents.

distribution switch to K,

z Set fan switch to A. The fan can also be
manually set: Set the rotary switch to
position
1 - 4. Intermediate settings are also

Heating
The amount of heat is dependent on the
coolant temperature and is thus not fully
attained until the engine is warm.
For rapid warming of the passenger
compartment:
z Set the air distribution switch to the
desired position – page 161.
z Set the centre rotary switch to the
desired temperature. We recommend a
value of about 22 °C.
z Set fan switch to A. The fan can also be
manually set: Set the rotary switch to
position 1 - 4. Intermediate settings are
also possible.
Climate control
Vehicles with Quickheat 3 : depending on
the outside temperature and the engine
temperature the passenger compartment
is heated up more quickly using an
auxiliary electric heater.
The auxiliary electric heater switches itself
on automatically.
The comfort and general well-being of the
vehicle occupants are to a large extent
dependent on a suitable ventilation and
heating setting.
To obtain a stratification of temperature in
the vehicle with the pleasant effect "cool
head and warm feet", set the air
distribution switch to K or J, set the
temperature switch to about 22 °C and
open the centre air vents.
