Ventilated storage compartment
Depending on vehicle model and configu-
ration, your vehicle is equipped with a stor-
age compartment under the front armrest
(page 244) 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
Open the storage compartment in front
of the armrest, see “Storage compart-
ment in front of armrest” (
page 244).
Push upper portion of switch.

of the armrest, see “Storage compart-
ment in front of armrest” (

iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at speed
setting 1 regardless of the air distribu-
tion control setting.
!Do not obstruct the air vent in the stor-
age compartment.iThe compartment can get very warm
due to its confined space. When storing
heat sensitive objects in the compart-
ment, close the air vent while heating
the passenger compartment.
