ZA WARNING
Applies to: vehicles with Audi virtual cockpit
If there is a severe malfunction in the instru-
ment cluster, the display may turn off. The wa
indicator light may also turn on. Stop the ve-
hicle safely. See an authorized Audi dealer or

authorized Audi Service Facility for assistance.

@ Tips
— The following pages will primarily show il-
lustrations of the multi-color analog instru-
ment cluster*. The display and/or position
of the element shown may vary in mono-
chrome instrument clusters or in the Audi
virtual cockpit*.
— You can select the units used for tempera-
ture, speed, and other measurements in the
Infotainment system > page 230.
— Speeds are displayed in mph (miles per
hour) or km/h (kilometers per hour).
— If there is a malfunction in the instrument
cluster, DEF will appear in the trip odometer
display. Have the malfunction corrected as
soon as possible.
— Depending on vehicle equipment, the in-
strument illumination (needles and gauges)
may turn on when the lights are off and the
ignition is switched on. The illumination for
the gauges reduces automatically and even-
tually turns off as brightness outside in-
creases. This function reminds the driver to
turn the low beams on at the appropriate
time.
Coolant temperature
display
Applies to: vehicles with a coolant temperature indicator
The coolant temperature display @) > page 14
only functions when the ignition is switched on.
To reduce the risk of engine damage, please ob-
serve 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 311.
@) 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.
—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
Audi dealer or authorized Audi Service Fa-
cility for assistance.
Tachometer
The tachometer (2) > page 14 displays the engine
speed in revolutions per minute (RPM). The be-
ginning of the red zone in the tachometer indi-
cates the maximum permissible engine speed for
all gears once the engine has been broken in and
when it is warm. Before reaching the red zone,
you should shift into the next higher gear, choose
the "D" or "S" selector lever position, or remove
your foot from the accelerator pedal.
Displaying the tachometer
Applies to: vehicles with plug-in hybrid drive
> Open the first vehicle functions tab using the
<1/D button on the multifunction steering
wheel.
> Applies to: vehicles with analog instrument
cluster: Turn the left thumbwheel on the multi-
function steering wheel until the Tachometer
appears in the instrument cluster.

Warm and cold
Climate control system
Your vehicle has a deluxe automatic climate con-
trol system with two zones where the tempera-
ture, air distribution, and amount of air can be
adjusted separately on the left and right front
sides.
The climate control system circulates, warms or
cools, and removes humidity from the air in the
vehicle interior. It is the most effective when the
windows and panoramic glass roof* or power
top* 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.
Presets
Several functions can be preset in the Infotain-
ment system.

ty.


ZA WARNING
Poor visibility can lead to accidents.
— For safer driving, keep all windows free of
ice, snow and fog.
— Become familiar with the correct use and
function of the climate control system as
quickly as possible, especially with the de-
frosting and defogging functions.
— 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

() Note
— If you suspect that the climate control sys-
tem is damaged, switch the system off to
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. See an authorized Audi dealer
or authorized Audi Service Facility.
@) For the sake of the environment
— Energy can be saved by switching off the A/C
mode.
— In vehicles with the efficiency program”, you
can find other consumption information and
more economy tips > page 23.
iG) 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, 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 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 climate control settings are automati-
cally stored and assigned to the vehicle key
that is in use. These settings are different
when the power top* is open or closed.

The functions can be switched on and off by
pressing the buttons or adjusted by turning the
knob. The LED in a button will light up when the
function is switched on.
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
engine coolant has reached a certain tempera-
ture.
AUTO Automatic mode or eco mode*
Automatic mode maintains a constant tempera-
ture inside the vehicle. Air temperature, airflow
and air distribution are controlled automatically.
AUTO mode switches off once a button in the cli-
mate control system is pressed.
Applies to: vehicles with eco mode: Pressing the
AUTO button briefly when automatic mode is ac-
tive will activate the energy-saving mode of the
climate control system. eco will appear on the
control panel display. You can end eco mode by
pressing the AUTO button again.
A/C cooling mode
The cooling mode only functions with the blower
turned on. 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
66
mode is switched off. This can cause fog on the
windows. The cooling mode switches off auto-
matically when there are cold outside tempera-
tures.
@ / @ Temperature
The temperature for the driver's and front pas-
senger's side can be adjusted separately with the
dials @/@). Temperatures between 60 °F
(+16 °C) and 84 °F (+28 °C) can be set. If outside
of this range, LO or HI will appear in the climate
control system display. In both settings, the cli-
mate control runs constantly at the maximum
cooling or heating level. The temperature is not
regulated.
Synchronization: Pressing and holding the AUTO
button for two seconds transfers the tempera-
ture setting for the driver to the front passeng-
er's side. This applies a temperature change to
the front passenger's side.
S8 Blower
Using the dial $8, you can manually adjust the
volume of air generated by the blower to your
preference. The blower should always run at a
low setting to prevent the windows from fogging
and to ensure a continuous exchange of air inside
the vehicle. To have the blower regulated auto-
matically, press the AUTO button.

The air distribution can adjusted with the but-
tons. To have the air distribution regulated auto-
matically, press the AUTO button.
The round air vents in the cockpit are adjustable
> page 68.
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.
Foot vents are located under the front seats and
adjustable vents on the end of the center console
to heat the rear of the vehicle.
& Defrosting
The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The maximum amount of air flows mainly from
the vents below the windshield. Recirculation
mode switches off. The temperature should be
set at +72°F (22°C) or higher. The temperature is
controlled automatically. In the & setting, the
A/C cooling mode switches on automatically, de-
pending on the outside air temperature.
The AUTO button switches the defroster off.
<> Recirculation mode
The recirculation mode can be turned on manual-
ly or automatically*.
— 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 >
Air conditioning > Auto recirculation. The air
quality sensor that is designed for diesel and
gasoline exhaust automatically switches the re-
circulation 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.
@ Rear window heating
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.
To prevent the rear window defogger from
switching off automatically, press and hold the
® button for more than two seconds.
#/ Seat heating*
Pressing the a button switches the seat heating
on at the highest setting (level 3). The LEDs indi-
cate 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.
After approximately 10 minutes, the seat heating
automatically switches from level 3 to level 2.

Z\ 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.
G) Tips
If the front passenger's seat heating is turned
on, it will not turn on again automatically if
more than 10 minutes have passed between

Driving

— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Avoid driving at high speeds.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Do not let the engine run while the vehicle
parked.
— Use the Start/Stop system.
— Utilize the engine braking effect.
— Avoid driving short distances when possible.
— Plug-in hybrid drive: brake early and evenly to
use the recuperation function.
@) Tips
The amount of noise produced by the vehicle
can increase significantly when driving with a
sporty style. Show respect to others around
you and the environment with the way you op-
erate your vehicle, especially at night.
Energy management
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
G) Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— The vehicle battery will gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
82
electrical equipment will be limited or
switched off.
S Engine stopped: power steering and brake
booster not possible
There is a malfunction in the engine or the fuel
supply. More force is needed to steer and brake
the moving vehicle when the engine is stopped.
If the vehicle is rolling, try to bring it to a stop off
to the side from moving traffic. See an author-
ized Audi dealer or authorized Audi Service Facili-
ty for assistance.
EB EB Drive system: malfunction! Safely stop
vehicle
There is a malfunction in the plug-in hybrid sys-
tem. The brake booster and the power steering
may stop working. Stop the vehicle immediately
at a suitable location or as soon as possible. Park
the vehicle in a safe place outdoors that is not
near buildings, roof overhangs, carports or simi-
lar structures. Switch the ignition off. Have the
problem corrected by an authorized Audi dealer
or authorized Audi Service Facility.
B i B Electric drive: overheated! Safely stop
vehicle and check coolant
The coolant level is too Low or the coolant tem-
perature is too high. Stop the vehicle in the out-
doors as soon as it is safely possible. Switch the
ignition off.
Read the important safety precautions > A in
Coolant on page 312 and check the coolant level
= page 312. If the coolant level is OK, the mal-
function may be caused by the system overheat-
ing. Let the vehicle's electric drive system cool
down for some time.
— If the message turns off after cooling down and
switching the ignition back on, you can contin-
ue driving. Contact an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.
— If the indicator light stays on, contact an au-
thorized Audi dealer or authorized Audi Service
Facility.

Trailer towing

Trailer towing
Driving with a trailer
General information
Your vehicle is primarily intended for transport-
ing people and luggage. However, if you drive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg-
ulations.
Driving with a trailer affects the vehicle's energy
usage, performance, and wear. It also requires
higher concentration from the driver.

Z\ WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Trailer hitch

Only use a trailer hitch with a removable ball
hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle, the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely
mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol-
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys-
tem must be designed for additional load and
contain enough coolant > @.
CG) Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out-
side temperatures are high. Otherwise, this
increases the risk of engine damage.
Operating instructions
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handling. To have the lowest im-
pact as possible, load the trailer according to
these criteria:
— Store objects in the vehicle luggage compart-
ment, if possible. The vehicle should always
carry the heaviest possible load and the trailer
should have the lightest possible load.
— Distribute the load in the trailer so that the
heavy objects are as close to the axle as possi-
ble.
— Secure objects so that they do not slide.
— Utilize the maximum permitted tongue weight
if possible.
Tires
Set the tire pressure on your vehicle for a “full
load”; see the tire pressure sticker > page 330. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's specifica-
tions.
The trailer and the vehicle should be equipped
with winter tires when driving in winter tempera-
tures.
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you
must attach additional exterior mirrors. Adjust
them so you have a sufficient visibility behind
you.
