Heating and air conditioning
Your Volvo is equipped with a heating system combined with air
conditioning. Depending on which function you select, warm or cool/
cold air is distributed to the different parts of the passenger
compartment. A slight amount of condensation may be emitted from the
air vents when the air conditioning is initially switched on. This can
occur when both humidity and ambient temperature are high and is
normal.
Air mix (fresh air)
The center panel vents have an air mix function which allows fresh air to
enter the passenger compartment when the vents are open (position B).
This function is designed to allow you to direct cool air toward your face
while directing warmer air to the rest of the passenger compartment.
To warm/cool the compartment as quickly as possible, the air mix
control should be in the closed position.

Refrigerant
Volvo cares about the environment. The air conditioning system in your
car contains a CFC-free refrigerant - R134a. This substance will not
deplete the ozone layer. The system contains 1.63 lbs (0.75 kg) R134a
and uses ZXL 100PG (type PAG) oil.
NOTE: All maintenance on the climate control systems should be
carried out by an authorized Volvo service technician only.
