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

The system is always at operational readiness, except
when manually switched off, see page 147.
The climate control only operates with the engine
running.
The air conditioning will not engage (no cooling) if the
economy mode AC
OFF
is selected, see page 147.
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.Notes:
Do not obstruct the air f low by placing objects on the air
flow-through exhaust slots on the back left and right
trim panel in the rear cargo compartment.
Also keep the air intake grill in front of the windshield
free of snow and debris.
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
Light Truck 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.

While driving, use this setting only temporarily,
otherwise the windshield could fog up.
To switch the climate control on again, set air volume
control switch to any speed.Economy mode
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.

Turn the electronic key in starter switch to position 2.
To select:
Press the F button in the control panel of the
automatic air conditioner. The indicator lamp in the
button illuminates.
To c a nc el:
Press the F button in the control panel of the
automatic air conditioner. The indicator lamp in the
button goes out.Notes:
Heavy accumulation of snow and ice should be removed
before activating the defroster.
The rear window defroster uses a large amount of power.
To keep the battery drain to a minimum, turn off the
defroster as soon as the rear window is clear.
The defroster is automatically turned off after
approximately 6–17 minutes of operation depending on
the outside temperature and vehicle speed.
If several power consumers are turned on
simultaneously, or the battery is only partially charged,
it is possible that the defroster will automatically turn
itself off. When this happens, the indicator lamp inside
the switch starts blinking.
As soon as the battery has sufficient voltage, the
defroster automatically turns itself back on.
