The setting of the automatic climate control and the 
memory settings are stored together for each individual 
electronic key or for both KEYLESS-GO-cards (vehicles 
with KEYLESS-GO) when the electronic key is removed 
from the starter switch or when the vehicle is locked 
using the KEYLESS-GO-card. 
The stored settings are activated when the electronic 
key is inserted into the starter switch or when the 
vehicle is unlocked using the KEYLESS-GO-card 
(vehicles with KEYLESS-GO). See page 108 for memory 
function and page 166 for automatic climate control.

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.  

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

cluster displayPractical hints Car care Index 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, 
selected interior temperature and the actual interior 
temperature of the vehicle. With the automatic climate 
control switched off, the air volume and distribution can 
still be set manually.
There are three basic settings for the automatic mode:
•Automatic air volume control
•Automatic air outlet control, left and right
•Automatic air outlet control, center, see page 167
We recommend these settings to be used all year round.Air volume and distribution are controlled 
automatically.
We recommend to set the temperature switches on the 
left and right to 72
°F (22
°C). Please make changes from 
this setting to suit your personal requirements.
