Heating and cooling

Automatic air recirculation

For optimum air quality inside the vehicle, close

all windows and doors and press on AIR Quality.

The air quality display only shows the air pollu-

tion due to particulate matter (PM2.5). For tech-

nical reasons, there may be variations between

the values measured in the vehicle and the values

measured by other instrumentation systems.

If this function is switched on in the air condition-

er settings menu ðpage 93, air recirculation is

regulated automatically when air pollution is de-

tected ð

WARNING

The values shown by the system are approxima-

tions which may deviate from the real conditions.

Under certain circumstances, the system may not

be fully available or may not display any values

for a limited period, or the measurements may

be implausible.

If the air recirculation function is used for a

long period, the concentration of CO can

build up inside the vehicle. This can cause per-

sonal discomfort and may even lead to an ac-

cident! Switch off the air recirculation or auto-

matic air recirculation immediately and venti-

late the vehicle if you experience any discom-

fort.

– When the vehicle is stationary

– In a car wash

A driver message indicating the cause and possi-

ble remedy may appear in the event of a fault. To

display the driver messages again, open the noti-

fication centre on the centre display. Try switch-

ing the air conditioning on later or after the vehi-

cle is next switched on.

Auxiliary heating/

ventilation

If a fault persists, drive to a qualified workshop

soon and have it rectified.

Introduction

You can control the auxiliary heating/ventilation

via the centre display or via the myAudi app.

Air quality display

When the air conditioner function is started, it

automatically selects whether the auxiliary heat-

ing or auxiliary ventilation is switched on, de-

pending on the ambient conditions.

The auxiliary heating warms up the inside of the

vehicle, while the auxiliary ventilation draws in

fresh air and can lower the temperature inside

the vehicle, depending on the ambient tempera-

ture. The function can be used either when the

engine is off or when driving (for instance while

the engine is warming up).

Fig. 69 Central display: air quality display

You can have air quality information displayed.

►

Select:  > Air quality

Conditions for operation

A sensor determines the particulate level

(PM2.5) outside and inside the vehicle. The val-

ues measured are each displayed as an air quality

index (AQI) on a colour scale 1 . A value in the

green area indicates very high air quality.

– There is enough fuel in the tank.

– The vehicle battery is sufficiently charged.

Information on the auxiliary heating/

ventilation

You can set up to five timers for the departure

time.

– The auxiliary heating/ventilation will not switch

on or will switch itself off earlier than intended

if the battery charge or fuel level is low.

– The auxiliary heating/ventilation system heats/

cools the interior to the temperature last selec-

ted on the air conditioner control bar.

A departure time specifies when the vehicle inte-

rior is to reach the most recently selected tem-

perature. The departure time must be within the

next six days. The auxiliary heating will continue

to run for several minutes after the departure

time is reached.

– If the auxiliary heating/ventilation is on, it is

not switched off automatically when the engine

is started or stopped.

►

Select Departure times.

Select Add new departure time.

Set the time and day.

Select Repeat to set a repeat timer.

►

– At low outside temperatures, some visible wa-

ter vapour may form in the engine compart-

ment. This is a normal phenomenon, and no

reason for concern.

►

Select Store setting.

The timer has been set.

The auxiliary heating/ventilation can be switched

on/off immediately even if a timer has been set.

This has no effect on the programmed timer set-

ting as long as the auxiliary heating/ventilation is

not switched off manually during the program-

med period.

WARNING

– The auxiliary heating must not be allowed to

run when the vehicle is in a confined space –

risk of poisoning!

– Never have the auxiliary heating switched on

when refuelling the vehicle – risk of fire!

– Because of the high temperatures which oc-

cur when the auxiliary heating is running,

make sure when parking the car that the ex-

haust outlet under the car is not obstructed

in any way and that the exhaust gases do

not come into contact with flammable ma-

terials (fire risk).

Heating mode for next departure

ventilation is active.

You can set the operating time and switch the

auxiliary heating/ventilation on/off immediately

by selecting  Switch on auxiliary heating.

When a function is switched on, a white bar will

light up in the button.

If the  symbol in the button is lit, a timer is

Driver messages about the auxiliary

heating/ventilation

The sticker in the engine compartment provides

information about the type of lubricant used in

the vehicle’s air conditioning system. For infor-

mation about the quantity of lubricant used,

please contact a qualified workshop.

The following driver messages may appear, de-

pending on the equipment installed in your vehi-

cle:

 Auxiliary heating/ventilation: fault. Not

Air conditioner evaporator

available

Components from old vehicles or recycled com-

ponents must never be used to repair the air con-

ditioner evaporator.

If this message appears, a system malfunction

has occurred. Drive to a qualified workshop soon

and have the fault rectified.

WARNING

Information on fluids in

the air conditioner

Maintenance work on the air conditioning sys-

tem must only be carried out by qualified and
