The automatic climate control
removes considerable moisture
from the air during operation in the
cooling mode. It is normal for water
to drip on the ground through ducts
in the underbody.
The desired interior temperature
can be selected separately for the
left and right side of the passenger
compartment.
Important!
This vehicle is equipped with an
air conditioner system that uses
R-134a (HFC: hydrofluorocarbon)
as a refrigerant. Repairs should
always be performed by a qualified
technician, and refrigerant should
be collected in a recovery system
for recycling.
