2024 Audi A4 Sedan Specs, Price, Features, Mileage and Review

Warm and cold

Climate control system

Description
One of the following options may be available, depending on vehicle equipment:

A deluxe automatic climate control system with three zones where the temperature, air distribution, and air supply can be set separately on the left and right front sides, and the temperature can be set separately in the rear

A deluxe automatic climate control system with four zones to individually adjust the temperature, air distribution, and amount of ventilation at all of the seats

The climate control system warms, cools, dehumidifies, and filters the air in the vehicle interior. It is the most effective when the windows and, depending on vehicle equipment, the roof are closed. If there is a build-up of heat inside the vehicle, ventilation can help to speed up the cooling process.

The deluxe climate control system automatically maintains a temperature once it has been set. In all heating mode functions, except defrost, the blower only switches to a higher speed once the coolant has reached a certain temperature.

Active combination filter
When the fan is running, the filter will reduce particulate matter and the concentration of pollen, as well as odours in the interior.

Tips

  • To prevent interference with the heating or cooling output and to prevent the windows from fogging over, the air intake in front of the windshield must be free of ice, snow, and leaves.
  • Condensation from the cooling system can drip and form a puddle of water under the vehicle. This is normal and does not mean there is a leak.
  • The energy management system may temporarily switch off certain functions, such as the seat heating or rear window defogger. These systems will be available again once the energy supply has been restored.

Operation in the cockpit

AC Cooling mode
The cooling mode only functions with the blower turned on. The air is not cooled and humidity is not reduced when cooling mode is switched off. This can cause fog on the windows. The cooling mode switches off automatically at low outside temperatures.

Depending on the vehicle equipment, you can select from the following settings for cooling mode by pressing the rocker switch 3 .

A/C MAX: activates the maximum cooling mode of the climate control system. To reduce unnecessary energy usage, only use this function briefly.

A/C ON: switches on the cooling mode and controls
it automatically.

A/C OFF: switches off the cooling mode.

AUTO Automatic mode
Automatic mode maintains a constant temperature inside the vehicle. Air temperature, airflow and air distribution are controlled automatically.
You can switch automatic mode on or off by pressing the knob 1 .

    Switch recirculation mode or automatic recirculation off and ventilate the vehicle at the first sign of unwellness.
  •  Individuals with reduced sensitivity to pain or temperature could develop burns when using the seat heating function. To reduce
  •  the risk of injury, these indi not use seat heating.

Note
To reduce the risk of damage to the seat heating elements, do not kneel on the seats or place heavy pressure on one area of the seat.

For the sake of the environment
Energy can be saved by switching off the A/C mode.
