Coolant temperature
indicator
The coolant temperature display @ > page 10,
fig. 3 only functions when the ignition is switch-
ed on. To reduce the risk of engine damage,
please observe the following notes about the
temperature ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem-
perature yet. Avoid high engine speeds, full accel-
erating and heavy engine loads.
Normal range
The engine has reached its operating tempera-
ture once the LEDs up to the center of the gauge
turn on. If the | indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high > page 17.
@) Note
— Auxiliary headlights and other accessories in
front of the air intake impair the cooling ef-
fect of the coolant. This increases the risk of
the engine overheating during high outside
temperatures and heavy engine load.

4S1012721BA
Instrument cluster

— The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized Au-
di dealer or authorized Audi Service Facility
for assistance.
Tachometer
The tachometer (2) > page 10, fig. 3 displays the
engine speed in revolutions per minute (RPM).
The beginning of the red zone in the tachometer
indicates the maximum permissible engine speed
for all gears once the engine has been broken in.
Before reaching the red zone, you should shift in-
to the next higher gear, choose the "D" or "S" se-
lector lever position, or remove your foot from
the accelerator pedal.
Engine speed limitation
Applies to: vehicles with engine speed limitation
If the BB indicator light turns on, the engine will
be automatically limited to the RPM displayed in
the instrument cluster. This protects the engine
from overheating.
The engine speed limitation deactivates once the
engine is no Longer in the critical temperature
range and you have released the accelerator ped-
al once.
If the engine speed limitation was activated by
an engine control malfunction, the B indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam-
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im-
mediately to have the malfunction corrected.
@) Note
The needle in the tachometer may only be in
the red area of the gauge for a short period of
time before there is a risk of damaging the
engine. The location where the red zone be-
gins varies depending on the engine.
Odometer

- = .
Fig. 4 Instrument cluster: odometer and reset button
The trip odometer and odometer are displayed in
the status line ©) > page 10, fig. 3.
The trip odometer shows the distance driven
since it was last reset. It can be used to measure
short distances. The odometer shows the total
distance that the vehicle has been driven.
Resetting the trip odometer

> Press the reset button [9-9] on the instrument
cluster. The trip odometer will be reset to zero.
@) Tips
Distances are displayed in mi (miles) or km
(kilometers).

Outside temperature
display
The outside temperature is displayed in the sta-
tus line ® page 10, fig. 3.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed in
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the engine.
At temperatures below 41 °F (+5 °C), a snowflake
symbol appears in front of the temperature dis-
play > A.

ZA\ WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the

Warm and cold
Climate control system
The climate control system warms, cools and re-
moves humidity from the air in the vehicle interi-
or. It functions most effectively when the win-
dows are closed. If there is a build-up of heat in-
side the vehicle, ventilation can help to speed up
the cooling process.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
Key recognition
Certain settings are automatically stored and as-
signed to the vehicle key being used.

ZA WARNING
Poor visibility can lead to accidents.
— For safer driving, keep all windows free of
ice, snow and fog.
— Become familiar as quickly as possible with
the correct use and function of the climate
control system, especially with the defrost-
ing and defogging function.
— When the temperature is below freezing,
only use the windshield washer system after
the
windshield has been warmed by the cli-
mate control system. The washer fluid could
freeze on the windshield and impair visibili-
ty.
@) Note
— If you suspect that the climate control sys-
tem is damaged, switch the system off to
56
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility.
— Repairs to the Audi climate control system
require special technical knowledge and
special tools. Have it inspected by an au-
thorized Audi dealership or a qualified elec-
tronics store.
(@) For the sake of the environment
Reducing the amount of fuel used also re-
duces the amount of pollutants that enter the
alr.
G) Tips
—To prevent interference with the heating
and cooling output and to prevent the win-
dows from fogging over, the air intake in
front of the windshield must be free of ice,
snow, or 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 tem-
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon as
the energy supply has been restored.
— The flows through the vents under the rear
window. Make sure the openings are not
covered when placing clothing on the lug-
gage compartment cover.

Fig. 67 Automatic climate control system: controls
You can control the functions through the dial,
buttons in the dial and the buttons. Press the
buttons to turn the functions on or off. The LED
ina button will light up when the function is
switched on.
Pressing the AUTO button and setting the tem-
perature to 72 °F (22 °C) is recommended. The
automatic climate control system automatically
maintains a temperature once it has been set.
The air temperature coming from the vents, the
blower speed, and the air distribution are also
automatically adjusted. In all heating mode func-
tions except defrost, the blower only switches to
a higher speed once the engine coolant has
reached a certain temperature.
& Blower
The blower speed can be adjusted in small incre-
ments using the dial (@). The blower should al-
ways run at a low setting to prevent the windows
from fogging and to ensure a continuous ex-
change of air inside the vehicle. You can adjust
the volume of air generated by the blower to your
preference. To have the blower regulated auto-
matically, press the AUTO button.
A/C Cooling mode
You can turn the cooling system on or off by
pressing the A/C button. The air is not cooled and
humidity is not removed when cooling mode is

switched off. This can cause fog on the windows.
Cooling mode switches off automatically when
the outside temperature is below zero.
The temperature can be adjusted with the control
©.
@ / @ Temperature
The temperature can be adjusted in small incre-
ments using the dial (2).
AUTO Automatic mode
The AUTO button turns on automatic mode. AU-
TO mode switches off once a button in the cli-
mate control system is pressed. Automatic mode
maintains a constant temperature inside the ve-
hicle. Air temperature, airflow and air distribu-
tion are controlled automatically.
Air distribution
The air distribution can be adjusted with the con-
trol @). To have the air distribution regulated au-
tomatically, press the AUTO button.
The air vents in the cockpit are adjustable.
To keep the front side windows from fogging up
in damp weather, we recommend opening the
side air vents and tilting them to the side.
<—& Recirculation mode
The recirculation mode can be turned on manual-
ly or automatically*.

Warm and cold

— Switching manual recirculation mode on and
off: Press the > button.
— Automatic* recirculation mode: auto recircula-
tion needs to be activated in the Infotainment
system. Select in the Infotainment system:
[MENU] button > Vehicle > left control button >
Vehicle settings > Air conditioning > Auto re-
circulation. The air quality sensor that is de-
signed for diesel and gasoline exhaust auto-
matically switches the recirculation mode on or
off depending on the level of pollutants in the
outside air.

In recirculation mode, the air inside the vehicle is
circulated and filtered. This prevents the unfil-
tered air outside the vehicle from entering the
vehicle interior. Switching recirculation mode on
when driving through a tunnel or when sitting in
traffic is recommended > A.
Pressing the <> button, AUTO or the & button
switches recirculation mode off.
® Defrosting
The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The optimum amount of air flows mainly out of
the vents under the windshield. Recirculation
mode switches off. The temperature is controlled
automatically.
The AUTO button switches the defroster off.
OFF climate control system
The climate control system is switched on and off
by pressing the button. It also switches on when
you press another button or a knob. Airflow from
outside is blocked when the climate control sys-
tem is switched off.
{s) Rear window defogger
If the rear window defogger is activated when
the ignition is switched on, the battery manage-
ment determines based on the battery charge if
it is possible to turn on. Otherwise, the rear win-
dow defogger functions with the engine running
and switches off automatically after approxi-
mately 10 - 20 minutes, depending on the out-
side temperature.
58
To prevent the rear window defogger from
switching
off automatically, press and hold the
® button for more than two seconds. This re-
mains stored up to approximately 15 minutes af-
ter turning off the ignition.
ss Seat heating*
If you press the button a the seat heating is
switched on at the highest level (3). The LEDs in-
dicate the temperature level. To reduce the tem-
perature, press the button again. To switch the
seat heating off, press the button repeatedly un-
til the LED turns off.
The seat heating switches automatically from
setting 3 to setting 2 after approximately ten mi-
nutes.

ZA WARNING
— You should not use the recirculation mode
for an extended period of time, because no
fresh air is drawn in and the windows can
fog when cooling mode is switched off. This
increases the risk of an accident.
— 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
To reduce the risk of damage to the seat heat-
ing elements, do not kneel on the seats or
place heavy pressure on one area of the seat.
(i) Tips
— The setting for the seat heating on the driv-
er's side is assigned to the key that is in use.
— If the front passenger's seat heating is
turned on, it will not turn on again automat-
ically if more than 10 minutes have passed
between switching the ignition off and
switching it on again.

Checking and Filling



— Never open the cap on the coolant expan-
sion tank when the engine is warm. The
cooling system is under pressure.
— To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“p” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to exhaust and chemi-
cals to as short a time as possible.
