iDuring severe operating conditions,
e.g. stop-and-go traffic, the coolant
temperature may rise close to 248°F
(120°C).!The engine should not be operated with
the coolant temperature above 248°F
(120°C). Doing so may cause serious
engine damage which is not covered by
the Mercedes-Benz Limited Warranty.

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
Residual heat and ventilation
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.Activating

iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the battery voltage.
Regardless of the temperature and air
volume set on the climate control panel
an interior temperature is aimed at by
72°F (22°C) and the blower runs for
the protection of the battery on low
stage.
