climate control MERCEDES-BENZ SPRINTER 2016 MY16 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 possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 26).
Overview of climate control systems
Important safety notes
Observe the recommended settings on the fol-
lowing 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.
iVentilate 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 interior
temperature will be reached more quickly.
iThe integrated filter can filter out most par-
ticles 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 con-
ditions, e.g. heavy air pollution, the interval
may be shorter than that stated in the Main-
tenance Booklet.

RSet the temperature control to the middle
level. Only change the temperature in small
increments.
If you wish to heat up the vehicle interior as
quickly as possible, set the temperature con-
trol to thezmaximum setting. When the
desired interior temperature has been
reached, turn the temperature control back
down in small steps.
ROnly use the settings for defrosting the wind-
shield briefly, until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up
as no fresh air is drawn into the vehicle in air-
recirculation mode. The indicator lamp in the
h button comes on when the function is
switched on.

Important information
If you switch off the "Cooling with air dehumid-
ification" function, the air inside the vehicle will
not be cooled (in warm weather) or dehumidi-
fied. 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 dehumidified
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 malfunction.

Window heating
Windshield heater
Windshield heater switch
The windshield heater consumes a lot of power.
You should therefore switch it off as soon as the
windshield is clear. The windshield heating oth-
erwise switches off automatically after
5 minutes.
XStart the engine.
XTo switch on/off: press thezswitch.
The indicator lamp in the zbutton comes
on when the windshield heating is switched
on.
If the indicator lamp in the zwindshield
heating button flashes, the on-board voltage is
too low. The windshield heating has switched off
prematurely or cannot be activated.
XSwitch off any consumers that are not
required, e.g. reading lamps or interior light-
ing.
If enough on-board voltage is available again
within 30 seconds, the windshield heating auto- matically switches on again. It otherwise
remains switched off.
Rear window defroster

Switching air-recirculation mode
on/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 cir-
culated.

you can activate or deactivate air-recirculation
mode for the rear-compartment climate control.
XSwitch on climate control (Ypage 101).
XTo activate: set the temperature control of

clockwise. Only change the temperature in
small increments.
Adjusting the air vents
Important safety notes
GWARNING
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-condi-
tioning system, you can also adjust the air vents
in the roof duct.
iFor 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:
Rkeep the air inlet grille on the hood free of
blockages, such as ice, snow or leaves.
Rnever cover the vents or the ventilation grilles
in the vehicle interior.

cle, turn thumbwheel ;to the left or for the
left-hand side of the vehicle, thumbwheel :

Adjusting the air vents in the roof duct
!
Always leave at least one air vent open.
If the rear-compartment air conditioning is
switched on and all the air vents are closed,
the air-conditioning system may be damaged.
On vehicles with rear-compartment air condi-
tioning, adjustable air vents are integrated into
the roof duct.
XTo adjust the airflow: open or close the air
flap in air vents :as needed.
XTo adjust the air distribution: turn air
vent :to the desired position.
Operating the auxiliary heating sys-
tem
Important safety notes
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, for example in
enclosed spaces or if the vehicle gets stuck in
snow. There is a risk of fatal injury.
Switch the auxiliary heating off in enclosed
spaces without extraction systems, e.g. in
garages. If the vehicle is stuck in snow and
you have to leave the auxiliary heating run-
ning, keep the exhaust pipe and the area
around the vehicle free of snow. To ensure anadequate supply of fresh air, open a window
on the side of the vehicle that is not facing into
the wind.
