Volkswagen Polo Service & Repair Manual: Comfort
| Being comfortable while driving leads to better
concentration and safe driving. Air conditioning makes drivers
and passengers more comfortable when temperatures or humidity
are high. While opening the windows or sunroof or increasing the
air flow can make vehicle occupants more comfortable, it also
exposes them to more noise, draughts, exhaust, pollen and dust. |
| A well-designed heating and air conditioning system can
increase comfort by controlling the temperature, humidity and
air flow inside the vehicle. This is done both when the vehicle
is moving and when it is stationary. |
| Air conditioning also offers these advantages: |
| It cleans the air that enters the vehicle interior. The damp
fins on the evaporator collect dust and pollen, which is then
removed by condensation. |
| Temperatures in a mid-size vehicle (for example: after a
short drive, outside temperature 30 °C (86 °F) in the shade and
the vehicle exposed to sunlight). |

| Environmental Information |
| Vehicles manufactured after 1992 have air conditioning
systems that use refrigerant R134a. This refrigerant does not
contain chlorine and does not deplete the ozone layer. |
| Refrigerant R12 was used through 1992. Due to its chlorine
atoms, this CFC has a high potential for depleting the ozone
layer as well as a tendency to increase the greenhouse effect. |
| Conversions are offered for existing systems filled with the
ozone-depleting substance R12. |
| Refer to Repair Manual for A/C systems with refrigerant R12.
This repair manual is only available in hard copy. |
| For environmental protection reasons, refrigerants must not
be released into the atmosphere. For laws and regulations. Refer
to
→ Chapter „Laws and Regulations“. |
