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
qualif ied technician, and refrigerant should be collected
in a recovery system for recycling.

3Air volume
4Automatic mode is selectedAutomatic 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 q uicker 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. Make 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 S is selected, see page 157.

Notes:
Do not obstruct the air f low 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 159 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 S can n ot be s witched of f. 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.Basic setting – automatic mode
In the automatic mode the automatic climate control
cools or heats the interior depending on the direction
and strength of the sunlight, outside temperature and
the selected interior temperature of the vehicle. With
the automatic mode switched off, the air volume and
distribution can still be set manually.
Briefly press left or right U button. The h, j
and k symbols will no longer be visible.
The economy mode and air recirculation functions will
be switched off. The automatic blower will be activated
at the same time.
We recommend to set the temperature switches on the
left and right to 72
°F (22
°C). This provides for
comfortable conditions in the vehicle.
Heating mode:
To lower headroom temperature, use thumbwheel
(4, page 148).
Air conditioning mode:
Open air outlets at dashboard top center (7, page 148)
for an even air distribution.
