Volkswagen Polo Service & Repair Manual: Refrigerant R134a Environmental Information

Vehicle air conditioning systems make use of the vaporization and condensation process. In this case, one works with a substance which boils easily, designated as refrigerant.
The refrigerant employed is tetrafluoroethane R134a, which boils at -26.5 °C (-15.7 °F) at a vapor pressure of 1 bar (14.5 psi).
R134a is a fluorocarbon and contains no chlorine.
R134a has a shorter atmospheric life span than refrigerant R12.
R134a does not damage the ozone layer. The ozone depletion potential is zero.
The greenhouse potential of R134a (Global Warming Potential = GWP) is approximately 1430 (the GWP of carbon dioxide is 1).
The global warming effect of R134a is ten times less than that of refrigerant R12.

Washing the vehicle
First read and observe the introductory information and safety warningsThe longer substances such as insects, bird droppings, resinous tree sap, road dirt, industrial deposits, tar, soot or road salt and other corrosive materials remain on the vehicle, the more damage they do to the paintwork. ...

Special Connector Systems
  Note If necessary, housing securing mechanisms (secondary locks) must be released or removed using specified tool before releasing the contacts. Refer to → Chapter „Secondary Lock“.     ...

Rolling Resistance Tires
Tire deformation when rolling causes the vehicle to loose energy that makes the rolling resistance noticeable. Deformation is significantly lowered on rolling resistance tires due to new construction and low-wear surface mixtures. ...
