climate control MERCEDES-BENZ SPRINTER 2014 MY14 Operator’s Manual

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment
of your vehicle that were available at the time
of going to print. Country-specific variations
are possible. Note that your vehicle may not
be equipped with all of the described func-
tions. This also applies to systems and func-
tions relevant to safety.
Read the information on qualified specialist
workshops (Y page 26). Overview of climate control systems
Important safety notes
Observe the recommended settings on the
following pages. Otherwise, the windows
could fog up.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
i Ventilate the vehicle for a brief period
during warm weather. In order to cool the
vehicle more rapidly, switch climate control
to air-recirculation mode briefly. This will
speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the airflow
into the vehicle interior. For this reason,
you should always observe the interval for
replacing the filter, which is specified in the
Maintenance Booklet. As it depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet. 112

Important information If you switch off the "Cooling with air dehu-
midification" function, the air inside the vehi-
cle will not be cooled (in warm weather) or
dehumidified. The windows could fog up more
quickly.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature
selected.
Condensation may appear on the underside
of the vehicle when in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.

off
Important safety notes When you switch on air-recirculation mode,
the windows could fog up more quickly, in
particular at low outside temperatures. Only switch on air-recirculation mode for a short
time.
You can deactivate the intake of fresh air if
unpleasant odors enter the vehicle from out-
side. The air inside the vehicle will only be
circulated.
Heating/air-conditioning system
Air-recirculation mode switches off automat-
ically after about 10to 30 minutes, depending
on the outside temperature.

Adjusting the air vents
Important safety notes
G
WARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
The center and side air vents are adjustable.
On vehicles with a rear-compartment air-con-
ditioning system, you can also adjust the air
vents in the roof duct.
i For virtually draft-free ventilation, adjust
the sliders of the center air vents to the
center position.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet grille on the hood free of
blockages, such as ice, snow or leaves.
R never cover the vents or the ventilation
grilles in the vehicle interior. Setting the center air vents
