Heating and air conditioning system134
Close air outlet vents
– Turn the vertical thumbwheel into the end position.
Redirecting air flow
– Swivel upward or downward the grille of the vents in order to
change the direction of the air flow using the vertically
arranged thumbwheel.
– Turn the horizontal thumbwheel on the vent to the right or left
in order to change the air flow to the appropriate side.
You can control the air distribution to the air outlet vents via the buttons of
the operating part of the Climatronic ⇒ page 130. Air outlet vents 3, 4
⇒ page 133, fig. 123 and 6 ⇒ page 133, fig. 124 can also be opened or
closed individually.
The air outlet vents 6 are only fitted on vehicles with higher centre
console.
Note
The air outlet vents 2 ensure in the ventilation and cooling mode for a
comfortable (no-draught) ventilation of the interior of the vehicle, also if the
air outlet vents 4 are closed.
Auxiliary heating (auxiliary heating and
ventilation)*
Description
The auxiliary heating (auxiliary heating and ventilation)
heats or supplies the interior of the vehicle with fresh air
independent of the engine.
Auxiliary heating (auxiliary heating )
The auxiliary heating (auxiliary heating) functions in connection with the
heater or with the Climatic or Climatronic.
It can be used when stationary, when engine is switched off for preheating
of the vehicle as well as while driving (e.g. during the heating phase of the
engine).
The auxiliary heating (auxiliary heating) warms up the coolant during the
combustion of fuel from the vehicle tank. The coolant warms up the air,
which (if the blower speed is not set to zero) flows into the occupant
compartment.
6)
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior
by switching on the blower, if the blower speed is not set to zero, whereby
the interior temperature is effectively decreased (e.g. with a vehicle
parked in the sun).
6)
However the coolant does not warm up the engine.
