cluster displayPractical hints Car care Index Climate control
The system is always at operational readiness, except
when manually switched off.
The 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 can be selected
separately for the left and right side of the passenger
compartment. Adjust the temperature settings in small
increments.
The 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 159. Notes:
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 171 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 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.

The function of this setting corresponds to the
automatic mode. However, because the air conditioning
compressor will not engage (fuel savings), it is not
possible to air condition in this setting.
Press S button to activate. The indicator lamp in the
button illuminates.
Press S button once again to return to the previous
setting. The indicator lamp in the button goes out.
Important!
In the S mode the windows could fog up on the

Climate control - OFF/ON
To switch the climate control off, set the air volume
control switch to position 0.
The fresh air supply to the vehicle interior is shut off.
While driving, use this setting only temporarily,
otherwise the windshield could fog up.
To switch the climate control on again, or set air volume
control switch to any speed.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 setting of the automatic
climate control. Air volume and distribution are
controlled automatically.
To s e l e c t :
Turn the electronic key in starter switch to position 1
or 0 or remove it altogether.
Press button T. The indicator lamp in the button
illuminates.
This function selection will not activate if the battery
level is insufficient.
The function switches off automatically:
•if the electronic key in starter switch is turned to
position 2,
•after approximately 30 minutes,
•if the battery voltage drops.

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.

Telephone, general
See separate instruction manual for instructions on how
to operate the telephone.
Wa r n i n g !
A driver’s attention to the road must always be his /
her primary focus when driving. For your safety
and the safety of others, we recommend that you
pull over to a safe location and stop before placing
or taking a telephone call. If you choose to use the
telephone while driving, please use the hands-free
device and only use the telephone when road and
traffic conditions permit.
Some jurisdictions prohibit the driver from using a
cellular telephone while driving a vehicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is covering
a distance of approximately 50 feet (approximately
14 m) every second.
Never operate radio transmitters equipped with a
built-in or attached antenna (i.e. without being
connected to an external antenna) from inside the
vehicle while the engine is running. Doing so could
lead to a malfunction of the vehicle’s electronic
system, possibly resulting in an accident and
personal injury.
