4M1012721BC
Driving

— Do not drive with winter tires during the summ-
er.
— Use the Start/Stop system.
— Utilize the engine braking effect.
— Avoid driving short distances when possible.
@) 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.
tg eel: [aay
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.
@) 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
electrical equipment will be limited or
switched off.
B Drive system: malfunction! Safely stop vehi-
cle
There is a malfunction in the drive system. The
brake booster and the power steering may stop
working. Stop the vehicle immediately or as soon
as possible and do not continue driving. Secure
the vehicle against rolling before exiting the vehi-
cle > page 99. Have the problem corrected by an
authorized Audi dealer or authorized Audi Service
Facility.
B Drive system: malfunction! Please contact
Service
There is a malfunction in the drive system. Drive
slowly to an authorized Audi dealer or authorized
Audi Service Facility to have the malfunction cor-
rected.
Start/Stop system
Applies to: vehicles with Start/Stop system
The Start/Stop system can help increase fuel
economy and reduce CO2 emissions.
In Start/Stop mode, the engine shuts off auto-
matically when stopped, for example at a traffic
light. If certain conditions are met, the engine
may stop before the vehicle has come to a com-
plete stop. If you press the accelerator pedal
when this happens, the engine will start and driv-
ing power will be transmitted.
The ignition and important assist systems such
as the brake booster will remain available during
the Stop phase. The engine will restart automati-
cally when needed.
The Start/Stop system is automatically activated
once the ignition is switched on.
Switching the Start/Stop system off and on
The & button is located above the selector lever
in the center console. The LED in the button turns
on when the function is switched off.
> Press & to switch the system on or off.
If you switch the system off during a Stop phase,
the engine will start again automatically.
Basic requirements
— The driver's door and hood must be closed.
—"P","N", or"D" must be engaged.
— The steering wheel must not be turned far in ei-
ther direction.
— The vehicle must have driven faster than 2 mph
(3 km/h) since the last time it stopped.
— The vehicle is not in trailer mode.

Trailer towing

in the trailer correctly will help to achieve this
weight. Having the tongue weight too low affects
the vehicle's handling.
You can determine the tongue weight using a
tongue weight scale, a bathroom scale, or a pub-
lic weigh station, for example.
The permitted tongue weight of your vehicle can
be found in the vehicle documentation or in
=> page 314.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handling. Load the trailer based
on the following criteria as much as possible:
— 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 269. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's specifica-
tions.
The tire pressure must be increased an additional
3 PSI (0.2 bar) for towing loads over 6,600 lbs
(3,000 kg).
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.
Exterior lighting
Follow the legal regulations for lighting on your
trailer that are applicable in the country where
you are operating the vehicle. Contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty for more information.
Before you start driving, check all lighting equip-
ment on the trailer while it is hitched to the vehi-
cle.
The headlight range control automatically ad-
justs the light range of the headlights.
The turn signals are activated in trailer mode if
the B indicator light blinks. If a turn signal on
the trailer or on the vehicle fails while in trailer
mode, the indicator light will not blink twice as
fast to indicate this.
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer. The chains should hang
enough so that the trailer can drive around
curves. However, they must not touch the
ground.
Air suspension
Applies to: vehicles with air suspension
The Audi drive select* comfort mode > page 113
must be selected before you adjust the tongue
weight on the trailer and hitch the trailer >,
=> page 114.
The air suspension trailer mode must be switched
on.
Applies to MMI: select on the home screen: VE-
HICLE > Settings & Service > Air suspension:
trailer.
Switch trailer mode off again when you are no
longer towing a trailer.
For vehicles with a factory-installed trailer hitch,
the air suspension trailer mode will automatically
switch on if you connect the trailer connector to
the socket.
When using rear carrier systems that are mount-
ed directly on the trailer hitch ball head, you can
also switch trailer mode off manually.

Driving information

Driving information
Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps the driver to
stay below a specified maximum speed. A warn-
ing threshold can be set in the MMI for this pur-
pose.
Once the speed slightly exceeds the stored
threshold, the speed warning system will alert
the driver with an indicator in the instrument
cluster and a warning tone. Once the speed drops
below the stored maximum speed, the indicator
will turn off.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.
@ Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.
Setting the warning threshold
Applies to: vehicles with speed warning system

Fig. 98 Instrument cluster: traffic sign recognition
The traffic sign recognition shows the traffic
signs detected by the front camera in the instru-
ment cluster display and in the head-up display”.
Data from the navigation system is also included
in the display. Up to three traffic signs can be dis-
played in the instrument cluster at once. The
speed limit that is currently applicable is dis-
played in the status line. If necessary, it will be
hidden if the system detects that turning right is
prohibited at a red light. The display in the head-
up display* can be switched off > page 26.
Within the limits of the system and depending
on the market, speed limit restrictions @ in
school zones, highways, construction zones, or at
night may be displayed.
Limitations
The traffic sign recognition is subject to certain
system limitations and may be unavailable or on-
ly partially available in the following situations:
— When visibility is poor, such as in snow, rain,
fog, or heavy spray
— When there is glare, for example from oncom-
ing traffic or the sun
— At high speeds
—If the camera's visual field > page 124 is cov-
ered, for example by dirt or stickers. For infor-
mation on cleaning, see > page 280.
— If the traffic signs are completely or partially
covered, for example by trees, snow, dirt, or
other vehicles

and Tires
General information
> Check your tires regularly for
damage, such as punctures,
cuts, cracks, and bulges. Remove
foreign objects from the tire
tread.
>If driving over curbs or similar
obstacles, drive slowly and ap-
proach the curb at an angle.
> Have faulty tires or rims re-
placed immediately.
>Protect your tires from oil,
grease, and fuel.
>Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
>Lay tires flat when storing and
store them ina cool, dry location
with as little exposure to light as
possible.

A WARNING
—Never drive faster than the
maximum permitted speed for
your tires. This could cause the
tires to heat up too much. This
increases the risk of an acci-
dent because it can cause the
tire to burst.


—Always adapt your driving to
the road and traffic condi-
tions. Drive carefully and re-
duce your speed on icy or slip-
pery roads. Even winter tires
can lose traction on black ice.

() Note
—Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom-
mends winter tires during the
winter months. Low tempera-
tures significantly decrease
the elasticity of summer tires,
which affects traction and
braking ability. If summer
tires are used in very cold tem-
peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
—Burnished, polished or
chromed rims must not be
used in winter driving condi-
tions. The surface of the rims
does not have sufficient corro-
sion protection for this and
could be permanently dam-
aged by road salt or similar
substances.

means, for example, that the tire
was produced in the 22nd week of
the year 2020.
Audi Original Tires
Audi Original equipment tires
with the designation “AO” have
been specially matched to your
Audi. When used correctly, these
tires meet the highest standards
for safety and handling. An au-
thorized Audi dealer or author-
ized Audi Service Facility will be
able to provide you with more in-
formation.
@) Mud and snow capability
“M/S” or “M+S” indicates the tire
is suitable for driving on mud and
snow. /4\ indicates a winter tire.
Composition of the tire cord
and materials
The number of plies indicates the
number of rubberized fabric lay-
ers in the tire. In general: the
more layers, the more weight a
tire can carry. Tire manufacturers
must also specify the materials
used in the tire. These include
steel, nylon, polyester and other
materials.
@) Maximum permitted load
This number indicates the maxi-
mum load in kilograms and
pounds that the tire can carry.
@ Uniform tire quality grade
standards for treadwear,
traction and temperature
resistance
Treadwear, traction, and tempera-
ture ranges > page 276.
@ Running direction
The arrows indicate the running
direction of unidirectional tires.
You must always follow the speci-
fied running direction
=> page 291.
Maximum permitted
inflation pressure
This number indicates the maxi-
mum pressure to which a tire can
be inflated under normal operat-
ing conditions.

differently even if they are the
same size > A.
>If you would like to equip your
vehicle with a tire and rim com-
bination that is different from
what was installed at the facto-
ry, consult with an authorized
Audi dealer or authorized Audi
Service Facility before making a
purchase > A.
Because the spare tire® is differ-
ent from the regular tires instal-
led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re-
placed with a regular tire as soon
as possible.
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds. For this rea-
son, in case of emergency, only
use a Spare tire* that is the same
circumference as the regular tires.


Z\ WARNING
—Do not use steel rims that are
17 inches or larger. Otherwise,


damage to the vehicle and an
accident could result.
—Only use tire/rim combina-
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
—For technical reasons, it is not
possible to use tires from oth-
er vehicles. In some cases, you
cannot even use tires from the
same vehicle model.
—Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif-
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
—Only use tires that are more
than six years old when abso-
lutely necessary and drive
carefully when doing so.
—Run-flat tires* may only be
used on vehicles that were

immediately by an authorized Audi dealer or
authorized Audi Service Facility.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved
roads), the message may be delayed.
— The driver is responsible for ensuring that

the wheels are attached correctly.

@) Tips
— The loose wheel warning system can also
stop working when there is an ESC malfunc-
tion.
— Using snow chains may result in a system
malfunction.
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.
>» Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > A\ in
General information on page 259. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
> Check the tire pressure after installing wheels
=> page 269.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.16 in (4 mm). The characteristics of winter tires
also decrease greatly as the tire ages, regardless
of the remaining tread.
(4) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
@) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the 4 symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
Use fine-mesh snow chains. They must not add
more than 0.53 in (13.5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZX WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.

C@) Note
— Snow chains can damage the rims and
wheel covers* if the chains come into direct
contact with them. Remove the wheel cov-
ers* first. Use coated snow chains.
— Do not install and use snow chains if there is
a malfunction in the air suspension*, be-
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
275

Wheels

only monitors the tire pressure you have stored.
Refer to the tire pressure label for the recom-
mended tire pressure for your vehicle
=> page 269, fig. 177.
Tire tread circumference and vibration character-
istics can change and cause a tire pressure warn-
ing if:
— The tire pressure in one or more tires is too low
— The tires have structural damage
— The tire was replaced or the tire pressure was
changed and it was not stored > page 278
— Tires that are only partially used are replaced
with new tires
Indicator lights

manual
iff appears after switching the ignition on or
while driving and the @ indicator light in the in-
strument cluster blinks for approximately one
minute and then stays on, there is system mal-
function. Try to store the correct tire pressures
= page 278. In some cases, you must drive for
several minutes after storing the pressures until
the indicator light turns off. If the indicator light
does turn off or turns on again after a short peri-
od of time, drive to an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.

Z\ WARNING
— If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu-
vers. Stop as soon as possible and check the
tires and their pressure.
— The driver is responsible for maintaining the
correct tire pressure. You must check the
tire pressure regularly.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved

278

roads), the tire pressure monitoring system
indicator may be delayed.
@) Tips
—The tire pressure monitoring system can al-
so stop working when there is an ESC mal-
function.

— Using snow chains may result in a system
malfunction.
—The tire pressure monitoring system in your
Audi was calibrated with “Audi Original
Tires” > page 266. Audi recommends using
these tires.
Storing tire pressures
Applies to: vehicles with Tire Pressure Monitoring System in-
dicator
If the tire pressure changes or a tire is replaced,
it must be confirmed in the MMI.
> Before storing the tire pressures, make sure the
tire pressures in all four tires meet the speci-
fied values and are adapted to the load
=> page 269.
» Switch the ignition on.
> Applies to MMI: Select on the home screen: VE-
HICLE > Settings & Service > Tire pressure
monitoring > Store tire pressure > Yes, store
now.
G) Tips
Do not store the tire pressures if snow chains
are installed.
Run-flat tires
Applies to: vehicles with run-flat tires
Run-flat tires can allow you to remain driving
when there is a loss of pressure.
Run-flat tires have reinforced sidewalls that pro-
tect
the tire if there is a loss of pressure.
If the tire pressure monitoring system indicates a
loss of pressure in one or several tires, you can
continue driving on run-flat tires for at least
20 mi (30 km). Drive to an authorized Audi dealer
or authorized Audi Service Facility immediately to
have the problem corrected.

—To reduce the risk of accidents, only wash
the vehicle when the ignition is off and fol-
low the instructions from the car wash oper-
ator.
—To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
—To reduce the risk of damage, do not wash
decorative decals* with a pressure washer.
—To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges, or similar items.
— When washing matte finish painted vehicle
components:
—To reduce the risk of cuts, protect yourself
from sharp metal components when wash-
ing the underbody or the inside of the wheel
housings.
— After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in-
creases the risk of an accident. The brakes
must be dried with a few careful brake appli-
cations.
— To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
— Never use protective wax. It can destroy
the matte finish effect.
@) Note — Do not place any stickers or magnetic
signs on vehicle components painted with
matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.

— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding (@) For the sake of the environment

—To reduce the risk of damage to the rims
and tires, compare the width between the
wheels on your vehicle with the distance be-
tween the guide rails in the car wash.
Only wash the vehicle in facilities specially de-
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.
