Notes on climate control system
The climate control system is operational
whenever the drive system is in operation.
You can operate the climate control system
in either the automatic or manual mode. The
system cools or heats the interior depending
on the selected interior temperature.
It can only function optimally when you are
driving with the windows closed.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.
G
Warning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced at an
authorized F-CELL Service Center as soon as
possible.
The air conditioning will not engage (no
cooling) if the A/C mode is deactivated.
G
Warning!
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise the windows could fog up,
impairing visibility and endangering you and
others.

Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing objects on
the air flow-through exhaust slots below the
rear window.
i If the vehicle interior is hot, ventilate the
interior before driving off, see "Summer
opening feature" (
control will then adjust the interior
temperature to the set value much faster.

Air conditioning
The air conditioning is operational while the
drive system is in operation and cools the
interior air to the temperature set by the
operator. In addition, the air conditioning
dehumidifies the interior air and helps
prevent window fogging.
G
Warning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
