Climate system
Introduction
Air conditioning
The vehicle is equipped with Electronic Climate Control (ECC). The climate control system cools, heats or
dehumidifies the air in the passenger compartment.
NOTE
The air conditioning can be switched off, but to ensure the best possible climate comfort in the passenger
compartment and to prevent the windows from misting, it should always be on.
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.
ProCarManuals.com

Sensor location
The sunlight sensor is located on the top side of the dashboard.
NOTE
The sunlight sensor monitors which side of the car that is most exposed to sunlight. This can mean that the
temperature may differ between the right and left-side air vents, even if the temperatures set for both sides of the
passenger compartment are the same.
The temperature sensor for the passenger compartment is located below the climate control panel.
The outside temperature sensor is located on the door mirror.
The humidity sensor (option) is located in the interior rearview mirror.
NOTE
Do not cover or block the sensors with clothing or other objects.
Side windows and moonroof
To ensure that the air conditioning works optimally, the side windows, and the optional moonroof should be closed.
Fog on the inside of the windows
The defroster function should be used to remove fog or mist from the inside of the windows. Keeping the windows
clean with a commercially available window washing spray will also help prevent fogging or misting.
Vents in the parcel shelf
NOTE
The air vents at the rear of the parcel shelf should never be obstructed.
Temporary shut-off of the air conditioning
The air conditioning is momentarily disengaged during full-throttle acceleration or when driving uphill with a trailer.
This may result in a temporary increase in cabin temperature.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Climate system maintenance
Special tools and equipment are required to maintain and carry out repairs on the climate system. Work of this type
should only be done by a trained and qualified Volvo service technician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a.
This substance
129 04 Comfort and driving pleasure
Climate system
will not deplete the ozone layer. The air conditioning system contains 1.8 lbs (800 g) of R134a. The systems 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 a trained and qualified Volvo service technician 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.
Interior Air Quality System (IAQS)
A multifilter helps reduce gases and particles in the incoming air, thereby reducing the levels of odors and
contaminants entering the vehicle. The air quality sensor detects increased levels of contaminants in the outside air.
When the air quality sensor detects contaminated outside air, the air intake closes and the air inside the passenger
compartment is recirculated, i.e. no outside air enters the vehicle. The filter also cleans recirculated passenger
compartment air.
NOTE
Contact your Volvo retailer for IAQS air filter replacement intervals.
Menu settings
The default settings for three of the climate system's functions can be changed in the menu system, see page 125
:
Blower speed in automatic mode, see page 132.
Recirculation timer for passenger compartment air, see page 132.
Automatic rear window defrosting, see page 102.
The functions can also be returned to factory settings in the menu system.

Ventilated front seats (option)
The ventilation system consists of fans in the seats and backrests that draw air through the seat upholstery. The cooling
effect increases as the air in the passenger compartment becomes cooler.
The ventilation is controlled by the ECC system, which takes into account the seat temperature, sunlight in the
passenger compartment, and the ambient temperature.
The ventilation can be used at the same time as seat heating.
The ventilation system can be activated when the engine is running. There are three comfort levels that produce
different cooling and dehumidification effects:
Level three: press the button once for maximum output - three indicator lights come on.
Level two: press the button twice for a lower output - two indicator lights come on.
Level one: press the button three times for the lowest output - one indicator light comes on.
Press the button a fourth time to switch off the function - the indicator light will go out.

Blower control
Turn the control clockwise to increase or counterclockwise to decrease the blower speed. Pressing the AUTO switch
will automatically regulate blower speed and override manual adjustment.
NOTE
If the blower is turned off completely, the air conditioning is disengaged, which may result in fogging on the
windows.
Heated front seats (option)
Press the button once for the highest heat level - three indicator lights come on.
Press the button twice for a lower heat level - two indicator lights come on.
Press the button three times for the lowest heat level - one indicator light comes on.

switched off by pressing the AC button.
Recirculation will not function while defrost is engaged.
The climate system will return to its previous settings when the defroster function is switched off.
Recirculation/air quality system
Recirculation
This function can be used to shut out exhaust fumes, smoke, etc from the passenger compartment. The air in the
passenger compartment is then recirculated, i.e., no air from outside the car is taken into the car when this function is
activated. The indicator light in the button will illuminate when recirculation is selected.
If the air in the car recirculates for too long, there is a risk of condensation forming on the insides of the windows,
especially in winter.
Timer
The timer function minimizes the risk of fogging, or stale air when the recirculation function is selected by
automatically switching off the function after a certain length of time, depending on the ambient temperature.
Activate/deactivate the function under Climate control settings
