Volkswagen PASSAT Passat 2019-2024 Heating and A/C system Car Owner Manuals

Heating and A/C system

• Heating, ventilation, and air conditioning

  • Introduction

    • The following systems may be installed in your vehicle:
    • The manual climate control system warms, cools, and removes humidity from the air.
    • Climatronic is an automatic air conditioning system which warms, cools and dehumidifies the air.
    • In automatic mode, Climatronic can automatically control the air temperature, air distribution and the volume of air.
    • The air conditioner is most effective when the vehicle interior is kept closed.
    • If there is a build-up of heat inside the vehicle, ventilation can help to speed up the cooling process.
