The automatic climate control only operates with the
engine running.
The system is always at operational readiness, except
when manually switched off.
In the automatic mode the automatic climate control
cools or heats the interior depending on outside
temperature and the selected interior temperature.
Make the temperature settings in small increments.
If the vehicle interior has been heated by direct sunlight
and is very hot, ventilate the interior (open door or
windows for a short period) before driving off
Keep the air intake grill in front of the windshield free
of debris and snow.
The air conditioning mode removes considerable
moisture from the air during operation in the cooling
mode. It is normal for water to drip on the ground
through ducts in the underbody.
If the economy mode AC
OFF
is selected, the air
conditioning compressor will not engage and it is not
possible to air condition in this setting. See page 117.Notes:
The interior temperature sensor (10) should not be
touched to maintain a precise temperature.
If the vehicle travels from shade into direct sunlight, a
sensor automatically increases the air volume
temporarily to maintain the interior temperature.
The automatic climate control will not remove moisture
from the air at low outside ambient temperatures.
The air conditioner switches itself off for its own
protection if refrigerant is lost. No cooling will then take
place. Economy mode AC
OFF
cannot be switched off.
Have the air conditioner checked by a Mercedes-Benz
Center should this happen.
Dustfilter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.
Severe conditions (e.g. strong air pollution) may require
replacement of the filter before its scheduled interval.
A clogged filter will reduce the air volume to the
interior.

setting.
Important!
In the mode AC
OFF
the windows could fog up on the

mode.Residual engine heat utilization
With the engine switched off, it is possible to continue
to heat or ventilate the interior for a short while,
dependent of the temperature set in the climate control.
Air volume and distribution are controlled
automatically.
To s e l e c t :
Turn the key in steering lock to position 1.
Press buttonT. The indicator lamp in the button

To s w i tch o f f :
Press buttonT. The indicator lamp in the button

This function selection is automatically switched off,
•if turning the key in steering lock to position 2,
•after approx. 30 minutes,
•if the coolant temperature is too low and
•if the battery voltage drops.
Note:
The fan switches to a lower speed independent of the
setting of the air volume control.
