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.
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.
