Get Warm and cold -> Climate control system Guide for Audi A5 4 Door Third Generation (2025-2026)

Warm and cold

Active combination filter

Warm and cold

Climate control system

Description

When the fan is running, the filter will reduce

particulate matter and the concentration of pol-

len, as well as odors in the interior.

Your vehicle has a deluxe automatic climate con-

trol system with three zones in which the tem-

perature, air distribution, and air supply can be

adjusted separately for the front left and right

sides, as well as the temperature in the rear.

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.

The climate control system warms, cools, dehu-

midifies, 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 ve-

hicle, ventilation can help to speed up the cooling

process.

– 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 tem-

porarily turn 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.

The automatic climate control system automati-

cally 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.

tem on or off. It also turns on when you press an-

other button or a knob. Airflow from outside is

blocked when the climate control system is

turned off.

SET REAR Function

A/C Cooling mode

Use the rocker switch 5 to select the function.

When the function is turned on, you can adjust

all settings for the rear using the climate control

system controls in the cockpit. The rear climate

control system controls cannot be operated at

the same time. This function turns off automati-

cally after a certain period of time or after leaving

the menu.

The cooling mode only functions with the blower

turned on. The air is not cooled and humidity is

not reduced when cooling mode is turned off.

This can cause fog on the windows. The cooling

mode turns off automatically at low outside tem-

peratures.

Depending on the vehicle equipment, you can se-

lect from the following settings for cooling mode

by pressing the rocker switch 3 :

 Blower

The blower setting should not be set too low in

order to prevent the windows from fogging and

to ensure a continuous exchange of air inside the

vehicle.

– A/C MAX: activates the maximum cooling

mode of the climate control system. To reduce

unnecessary energy usage, only use this func-

tion briefly. In unfavorable weather conditions,

this function may increase the fogging on the

windows.

You can adjust the volume of air generated by the

blower to your preference using the rocker switch

4 . To have the blower regulated automatically,

press one of the knobs 1 .

– A/C ON: turns on the cooling mode and con-

trols it automatically.

Air distribution

– A/C OFF: turns off the cooling mode.

To help prevent the front side windows from fog-

ging over, open the side air vents and angle them

toward the side windows.

AUTO Automatic mode

Automatic mode maintains a constant tempera-

ture inside the vehicle. Air temperature, airflow

and air distribution are controlled automatically.

You can turn automatic mode on or off by press-

ing the knob 1 .

You can use the rocker switches 2 to adjust the

vents where the air will flow out of. Press the

rocker switches 2 repeatedly until the desired

air distribution setting is displayed in the climate

control system controls. To have the air distribu-

tion regulated automatically, press one of the

knobs 1 .

 /  Temperature

You can adjust the temperature between 60°F

(+16°C) and 84°F (+28°C) by turning the knob

1 . If outside of this range, LO or HI will appear

in the climate control system display. In both set-

tings, the climate control runs constantly at the

maximum cooling or heating level.

 Defrosting

The windshield and side windows are defrosted

or cleared of condensation as quickly as possible.

Open the side air vents and angle them toward

the side windows. The maximum amount of air

flows mainly from the vents below the wind-

shield.

SYNC Synchronization

Use the rocker switch 5 to select the function.

When synchronization is turned on, the settings

must make sure that the seat heating is off

when starting the drive.

Vents

You can open and close the center and rear air

vents using the thumbwheels. The levers adjust

the direction of the airflow from the vents.

– When the seat heating is on, an alternating

magnetic field is created. Interactions such

as irritation of sensory organs or malfunc-

tions of active medical implants (such as

pacemakers, infusion pumps, or neurosti-

mulators) are very unlikely. If you have a

medical implant, seek medical advice from a

specialist if you have any questions.
