128 Climate control
Manual air recirculation mode
The manual air recirculation mode is
operated with the 4 button.
9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air
humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the
vehicle occupants to feel drowsy.
Air conditioning with the engine
not running
When ignition is off, the residual heat
or cooling in the system can be used
for climate control in passenger
compartment.
Press the AUTO button with the
ignition off. Residual air conditioning
on will appear briefly in the display.
Residual climate control can only
operate for a limited period of time. To
cancel, press the AUTO button.

Auxiliary heater

Air heater
Quickheat is an electric auxiliary air
heater which warms up the
passenger compartment more
quickly.
Coolant heater
Diesel-engined vehicles have a fuel-
powered auxiliary coolant heater
which warms up the engine coolant
when the engine is running.

Air vents

Adjustable air vents

At least one air vent must be open
while cooling is on in order to prevent
the evaporator from icing up due to
lack of air movement.
Air vents with adjuster wheel
To open or close the vent, turn the
adjuster wheel.
