Important!
This vehicle is equipped with an air conditioning
system that uses R-134a (HFC: hydrofluorocarbon) as a
refrigerant. Repairs should always be performed by a
qualified technician, and refrigerant should be collected
in a recovery system for recycling.

Te ch n i c a l

cluster displayPractical hints Car care Index Automatic climate control
The system is always at operational readiness, except
when manually switched off.
The automatic climate control only operates with the
engine running.
The temperature selector should be left at the desired
temperature setting. The temperature selected is
reached as quickly as possible.
The system will not heat or cool any quicker by setting a
higher or lower temperature.
The desired interior temperature and air distribution
can be selected separately for the left and right side of
the passenger compartment. Adjust the temperature
settings in small increments.
The automatic climate control 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.
The air conditioning will not engage (no cooling) if the
economy mode AC
OFF
is selected, see page 176. Notes:
The current settings (Temperature, Air volume, AC
OFF,
Activated charcoal filter, ON / OFF) are stored for each
electronic key before the electronic key is removed from
the starter switch or when the vehicle is locked using
the KEYLESS-GO-card (vehicles with keyless-go), see
key dependent memory settings on page 111.
Do not obstruct the air flow by placing objects on the air
flow-through exhaust slots below the rear window.
Also keep the air intake grill in front of the windshield
free of snow and debris.
The storage compartment between the front seats can be
ventilated. See page 178 for notes on ventilating the
storage space under the armrest in the center console.
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.
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.

Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.Automatic maximum cooling (MAXCOOL)
With the automatic climate control set to automatic, the
system will automatically switch to maximum cooling
output when necessary to achieve the set temperature
quickly, see page 171. The display shows
“AUTO MAXCOOL”.
The temperature setting cannot be changed during
maximum cooling operation.
Note:
By pressing one of the temperature control buttons, the
system will display briefly (approx. 5 seconds) the set
temperature in the display.

An activated charcoal filter markedly reduces bad odors
and removes pollutants from air entering the passenger
compartment.
Select activated charcoal filter:
The indicator lamp in the e button is not
illuminated.
Press e button briefly. The indicator lamp in the
button illuminates.
Switch off activated charcoal filter:
The indicator lamp in the e button is illuminated.
Press e button briefly. The indicator lamp in the
button goes out.
The system switches automatically to the air
recirculation mode, if the carbon monoxide (CO) or
nitrogen oxides (NO
X) concentration of the outside air
increases beyond a predetermined level.
The automatic air recirculation mode does not function
if economy mode ACOFF
is selected or if the outside
temperature has fallen below 40
°F(5
°C). The activated charcoal filter should be switched off
when windows fog up on the inside, or if the passenger
compartment needs to be quickly heated or cooled
down.
Switching on the activated charcoal filter and activating
convenience closing of power windows and sliding /
pop-up roof:
The indicator lamp in the e button is not
illuminated.
Press button e for more than 2 seconds, the side
windows and the sliding / pop-up roof will be closed. The
indicator lamp in the button illuminates.
Switching off activated charcoal filter and activating
convenience opening of power windows and sliding /
pop-up roof:
The indicator lamp in the e button is illuminated.
Press button e for more than 2 seconds, the side
windows and the sliding / pop-up roof return to the
position they were in before closing. The indicator lamp
in the button goes out.
