Ventilated storage compartment
Depending on vehicle model and configu-
ration, your vehicle is equipped with a stor-
age compartment under the front armrest
(page 232) 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

Turn switch at the tip of stalk in the di-
rection of arrow1.
The steering wheel is heated. Indicator
lamp2 comes on.
!The lighter socket can accommodate
12V DC electrical accessories (up to a
maximum of 85 W) designed for use
with the standard “cigarette lighter
plug”. Keep in mind, however, that con-
necting accessories to the lighter sock-
et (for example extensive connecting
and disconnecting, or using plugs that
do not fit properly) can damage the
lighter socket. With the socket dam-
aged, the lighter may no longer be able
to be placed in the heating (pushed-in)
position, or the lighter may pop out too
early with the lighter not hot enough.
iThe steering wheel heating is tempo-
rarily suspended while indicator
lamp2 remains on when
the temperature of the vehicle inte-
rior is above 86°F (30°C)
the temperature of the steering
wheel is above 95°F (35°C)
When these conditions do not apply
anymore, steering wheel heating con-
tinues.
