171 Automatic climate control
Te ch n i c a l
data Instruments

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. 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 AC
OFF
selected, see page 178. 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 113.
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 180 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 it is very hot, ventilate the interior (open door or
windows for a short period) before driving off.

Note:
The battery symbol# will appear in the automatic
climate control display some time before the residual
engine heat utilization is switched off if the battery
voltage drops.
