Audi A4: Climate control system
Description
Your vehicle has a deluxe automatic climate control
system with three zones in which the temperature,
air distribution, and air supply can be
adjusted separately for the front left and right
sides, as well as the temperature in the rear.
The climate control system warms, cools, dehumidifies,
and filters the air in the vehicle interior.
It is the most effective when the windows and
panoramic glass roof* are closed. If there is a
build-up of heat inside the vehicle, ventilation
can help to speed up the cooling process.
The automatic 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 odors in the interior.
WARNING
- You should not use the recirculation mode
for an extended period of time, because no
fresh air is drawn in. This can cause the windows
to fog, which increases the risk of an
accident. The CO2 concentration in the vehicle
interior can also increase when recirculation
mode is used for long periods of time,
which can impair concentration and affect
well-being. Switch recirculation mode off
and ventilate the vehicle at the first sign of
unwellness.
- Applies to: vehicles with seat heating: Individuals
with reduced sensitivity to pain or
temperature could develop burns when using
the seat heating function. To reduce the
risk of injury, these individuals should not
use seat heating.
Note
Applies to: vehicles with heated seats
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.
