Air conditioning
Air conditioning is an in tegral part of the
heating and ventilati on system, providing
cooled and dehumidifie d air for occupant
comfort. The dry airflow is effective in
preventing misting of windows and is also
beneficial at low external temperatures.
Air conditioning is automatically switched on
and controlled whenever the system is not
operating in ECON mode. Auto mode (Automatic systems)
Press AUTO to select automatic
operation of the system, both LEDs
in the switch will illuminate.
The system will adjust the heat
output, blower speed, air intake and airflow
distribution to maintain the selected
temperature(s) and re duce misting without
further adjustments.

External water deposits
The air conditioning system removes
moisture from the ai r and deposits excess
water beneath the vehicl e. Puddles may form,
but this is no cause for concern.
