Water or water vapour under the vehicle
If the humidity and temperature outside the
vehicle are high, condensation can drip o
the evaporator in the cooling system and form
a pool underneath the vehicle. This is normal
and does not indicate a leak!
When the outside humidity is high and the am-
bient temperature is low, condensation water
may evaporate when the stationary air condi-
tioning is operating. In this case, steam may
be released from underneath the vehicle. This
does not mean that the vehicle has any dam-
age.
Stationary air condition-
ing
Introduction
With the stationary air conditioning you can
cool, ventilate and heat the passenger com-
partment while the vehicle is parked. In winter,
you can also demist the windscreen and leave
it free of ice and snow (if the layer is thin).
