Depending on vehicle model and configu-
ration, your vehicle is equipped with a stor-
age compartment under the front armrest 
(page 245) which can be ventilated 
when the automatic air conditioning is 
switched on. If so equipped, the switch is 
located inside the storage compartment in 
the front. The air temperature is about the 
same as that of the center air vents.
The air volume is dependent on the setting 
of:
Air distribution control
Air volume control
Air vents in the dashboard
The air temperature is about the same as 
that of the dashboard air vents. It cannot 
be regulated separately.Switching ventilation on

of the armrest, see “Storage compart-
ment in front of armrest” (
page 245).

system cools or heats the interior depend-
ing on the selected interior temperature 
and the current outside temperature.
The automatic climate control system is 
adjustable individually for the rear passen-
ger compartment.
The control panel is located in the rear cen-
ter console.
Nearly all dust particles, pollutants and 
odors are filtered out before outside air en-
ters the passenger compartment through 
the air distribution system.
iThe booster blower allows air volume 
speed to the rear passenger compart-
ment to be increased at four different 
levels.
The temperature at the air vents for 
rear passenger compartment1 
and2 is the same as at the dashboard 
center air vents.

and systems controlled by that fuse will 
stop working.
The following aids are available to help you 
replace fuses (
