Air conditioning - A/C
Your car is equipped with a climate control system that includes either manually adjustable air conditioning or optional
Electronic Climate Control (ECC).
The air conditioning system can be switched off, but for optimal air quality in the passenger compartment and to
prevent the windows from fogging, the air conditioning should be left on - even in cool weather.
NOTE: In warm weather, a small amount of water may accumulate under the car when it has been parked. This water
is condensation from the A/C system and is normal.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Climate control maintenance
Your Volvo retailer has the tools and equipment required to maintain and carry out any necessary repairs on the
climate system. Work of this type should only be done by an authorized Volvo service technician.
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 1.2 lbs (530 g) R134a (HFC 134a), and uses PAG
oil.
Passenger compartment filter
Replace the cabin air filter with a new one at the recommended intervals. Please refer to your Warranty and Service
Records Information booklet, or consult your Volvo retailer for these intervals. The filter should be replaced more
often when driving under dirty and dusty conditions. The filter cannot be cleaned and therefore should always be
replaced with a new one.
NOTE: There are different types of cabin air filters. Ensure that the correct type is installed.
Display
The display above the climate control panel shows the climate settings that have been made.

Personal settings
There are two functions in the climate system that can be set to your preferences:
Blower speed to Auto mode (models with ECC only).
Timer controlled recirculation of the air in the passenger compartment. For information about how to make these
settings, see the Personal settings section on page 62
.
Models equipped with ECC (option)
Sensors
The sunlight sensor on the upper side of the dashboard and the passenger compartment temperature sensor, located
behind the climate system control panel, should not be obstructed.
Side windows and optional moonroof
The electronic climate control system will function best if the windows and moonroof are closed. If you drive with the
windows or moonroof open, it may be preferable to manually adjust the temperature and blower control (the LED in
the AUTO switch should be off).
Acceleration
The air conditioning system is temporarily switched off during full throttle acceleration.
