control
The following contains notes and recommen-
dations on optimum use of dual-zone climate control.
R Activate climate control using the Ãand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the defrosting function briefly
until the windshield is clear again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp in the ábutton goes out. 120

Activating/deactivating cooling with air dehumidification
General notes If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up
more quickly. Therefore, only deactivate the "Cooling with air-dehumidification" function
briefly.
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 drip from the underside of the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunction.
Switching cooling with air dehumidification on/off !
If the cooling with air dehumidification does not switch on, it is possible that the climate
control system has lost coolant.
Have the cooling with air dehumidification checked at a qualified specialist workshop. Canada only

WARNING
If you switch off the cooling function, the vehi- cle will not be cooled when weather condi-
tions are warm. The windows can fog up more
quickly. Window fogging may impair visibility
and endanger you and others.
In automatic mode, the set temperature is
maintained at a constant level. The system
automatically regulates the temperature of
the dispensed air, the airflow and the air dis-
tribution.
Automatic mode will achieve optimal opera-
tion if cooling with air dehumidification is also activated. If desired, cooling with air dehu-
midification can be deactivated.

Problems with the rear window
defroster
If the indicator lamp in the
ªrear window
defroster button flashes, the on-board volt-
age is too low. The rear window defroster has
deactivated prematurely or cannot be activa-
ted.

heat function
The "residual heat" function is only available
in Canada.
It is possible to make use of the residual heat
of the engine to continue heating the station- ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the coolant temperature and
on the interior temperature that has been set.
i The blower will run at a low speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated.

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. General notes
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 intake grill on the hood free of
blockages, such as ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.
i For virtually draft-free ventilation, adjust
the sliders of the air vents to the center
position.
i If the automatic climate control con-
stantly differs from the set temperature or
if undesired drafts are noticeable, proceed
as follows:
XOpen the side air vents
X Open the center air vents X
Open the rear air vents
X Set the temperature to 72 ‡ (22 †).
