Airborne properties
WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2002 Volkswagen Cabrio, 2001 Volkswagen Cabrio, 2000 Volkswagen Cabrio, 1999 Volkswagen Jetta, and 1999 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.
Escaped refrigerant gases are heavier than air and will gather first in low places, such as underneath the car. R-134a refrigerant gas displaces oxygen and may cause suffocation in low areas of poor air circulation.
