ture. The cooling function also
dehumidifies the air in the vehicle interior,
thus preventing the windows from fogging
up.

turn to its previous position if it has not been
moved to another position using the respective
window switch or tilt/sliding sunroof switch af-
ter it was closed with button,.

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.Residual heat and ventilation
(Canada only)
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.
!
If the air conditioning cannot be turned on
again, this indicates that the air conditioning is
losing refrigerant. The compressor has turned it-
self off.
Have the air conditioning checked at the nearest
authorized Mercedes-Benz Center.

If you switch on the residual heat function
when temperatures are high, only the ventilation
will be switched on.
