Why does the cooling system switch off automatically or cannot be
switched on?
• The engine is not running.
• The blower is switched off.
• The air conditioning system fuse has blown.
• The ambient temperature is lower than approxi3°C (+38°F).
• The air conditioning compressor of the cooling system has been temporarily switched off
because the engine coolant temperature is too high.
• There is a vehicle fault. The air conditioning system should be checked by a qualified workshop.
Settings for optimal road visibility
• Keep the air intake in front of the windscreen free from ice, snow or leaves to improve the
heating and cooling performance and prevent condensation on the windows

.
• Do not cover the air vents in the rear of the luggage compartment to allow air to flow through
the vehicle from the front to the rear.
• The maximum heating output and the fastest window defrosting results are achieved when the
coolant has reached its operating temperature.
Recommended settings for the heating and fresh air system or manual air
conditioning system
• Switch off air recirculation mode.
• Set blower to setting or .
• Set the temperature selector to the middle position.
• Open and position all vents on the dash panel.

Recommended Climatronic setup
• Press the
button.
• Set the temperature to +22°C (+72°F).
• Open and position the vents on the dash panel.
Air Care Climatronic
The allergen filter of Air Care Climatronic can additionally reduce the amount of pollutants and also
allergens that enter the vehicle interior.
The filters must be changed regularly to avoid impairing the performance of the air conditioning
system. If the vehicle is frequently used in severely polluted air, the filter must be replaced between
service events.
• Press the
button on the control panel.
• Touch the
Air Care
function button.
• Touch the
Active
function button to switch the Air Care function on or off.
Dust and pollen filter
The dust and pollen filter must be replaced regularly to prevent impaired performance of the manual
air conditioning system. If the vehicle is frequently used in severely polluted air, the filter must be
replaced between service events.
Water under the vehicle
If the humidity and temperature outside the vehicle are high,
condensation
can drip off the
evaporator in the cooling system and form a pool underneath the vehicle. This is normal and does
not indicate a leak.
If the outside humidity is high and the outside temperature low,
condensation
may evaporate when
the auxiliary heater is running

. If this is the case, steam may
appear underneath the vehicle. This is not a sign that the vehicle is damaged.
