Depending on your vehicle's equipment , various
parking aids will help you when parking and ma­
neuvering.
The
rear parking system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 125.
Parking system plus assists you when parking by
using audio and visual signals to indicate objects
detected in
front of and behind the vehicle
¢ page 125.
The rearview camera shows the area behind the
vehicle in the Infotainment display . The lines in
the rearview camera image help you to park or
maneuver ¢
page 126. The parking system plus
functions are also available
¢page 125.
The peripheral cameras give various views to
help you when parking or maneuvering
¢ page 128 . fhe parking system plus functions
are also available
¢ page 125.
A WARNING
- Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver 's attention. The driver is always
responsible when entering or leaving a park­
ing space and during similar maneuvers.
- Please note that some surfaces, such as
clothing, are not detected by the system.
-
- Sensors and cameras have blind spots in
which people and objects cannot be detect­ ed . Be especially cautious of small children
and animals .
- Always keep your eyes on the vehicle's sur­
roundings, using the rearview mirror as
well .
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The park­
ing system may be impaired as a result.
Have an authorized Audi dealer or author-
124
ized Audi Service Facility check their func­
tion .
(D Note
-Some objects are not detected or displayed
by the system under certain circumstances:
- Objects such as barrier chains, trailer draw
bars, vertical poles or fences
- Objects above the sensors such as wall ex­
tensions
- Objects with certain surfaces or structures
such as chain link fences or powder snow
- If you continue driving closer to a low ob­
ject, it may disappear from the sensor range. Note that you will no longer be
warned about th is obstacle .
- Keep enough distance from the curb to
avoid damage to the rims.
(D Tips
-The system may provide a warning even
though there are no obstacles in the cover­
age area in some situations, such as :
- certain road surfaces or when there is tall
grass.
- external ultrasonic sources such as from
cleaning vehicles .
- in heavy rain, snow, or thick vehicle ex­
haust.
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system . When doing
this, there should be good light and weath­
er conditions.
- You can change the volume of the signals
and the display ¢
page 131.
-Please refer to the instructions for trailer
towing in
¢page 132.
- What appears in the infotainment display is
somewhat time-delayed.
- Th e sensors must be kept clean and free of
snow and ice for park assist to operate.

prevent collisions -there is still a risk of ac­
cidents!
- Press the accelerator pedal carefully when
accelerating on smooth, slippery surfaces
such as ice and snow. The drive wheels can spin even when these control systems are
installed and this can affect driving stability
and increase the risk of a coll ision.

Intelligent Technology
(D Tips
- The ABS and ASR only function correctly
when all four wheels have a sim ilar wear
condition. Different tire sizes can lead to a
reduction in engine power.

Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with a ll wheel drive
¢ page 332, Snow chains.
Replacing tires
For vehi cles w ith all whee l dr ive, only whee ls with
the same rolling circumferen ce shou ld be used .
Avoid using tires w ith different tread depths
¢ page 324, New tires or wheels .
Offroad vehicle?
Your Audi is not an offroad vehicle - the re is not
e nough g ro und clea rance. For this reason, avo id
d iffi cult terrain .
_& WARNING
-Also, in vehicles with all wheel drive, adapt
yo ur driving style to the current road and
t raffic conditions . Do not let the increased
sa fety provided tempt you into tak ing risks,
because th is increases the r isk of an acci­
dent.
- The brak ing ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not diffe rent from a two whee l dr ive vehi­
cle . Do not be tempted to accelerate to a
high spee d when t he road is slippe ry, be­
ca use this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hy droplane" if dr iving at speeds that
are too hig h. Unlike front whee l drive
vehicles, the eng ine does no t r ev highe r su d­
denly when the vehicle begins hydroplaning .
For this reason, pay attention to the road
condit ions regar dless of you r speed to re­
duce the r isk o f an accident.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a ve hicle w ith a co nventional e nergy sys ­
tem is not driven for a long time, the battery is
138
dra ined by equipment (for examp le, the immobi l­
izer) . In certain circ umstances, there could may
not be enough ene rgy to sta rt the eng ine.
Yo ur vehicle is equipped wi th an inte lligen t ener ­
gy management system for dist ributing elec trici ­
ty. This significant ly improves the starting ability
and increases the batte ry life.
The ene rgy management sys tem Is m ade up of
batte ry diagnosis , standby current manage­
ment
and dynamic ene rgy management .
Battery diagnosis
The ba ttery diagnos is determines the batte ry
c ha rge level. The sensor s de ter mine the batte ry
vo ltage, the batte ry cu rrent, and the batte ry
tempera ture. The current cha rge level and the
perfo rmance of the battery a re determined base d
on this .
Idling current management
The idling cur rent m an age ment decreases the
energy used while parked . With the engine
switched off, it manages the energy distrib ution
to the different e lectr ica l components. Data from
the battery d iagnosis is taken into account for
th is.
Depend ing on the battery charge leve l, electrical
equipment is switched off one item after the oth ­
er, to prevent the battery from drain ing and to
maintain the sta rting ability.
Dynamic energy management
W hile driv ing, dynam ic energy man agement dis ­
tributes the appropr iate amo unt of energy to the
electrica l eq uipment. It contro ls t he battery
charge level so that mo re energy is not used then
i s be ing generated in order to maintain an opti­
mal battery c harge level.
(D Tips
- Energy management cannot overcome the
laws of physics. Note that the charge level
and length of the battery life are limited.
- When the sta rting ability is endangered, the

bolts and a special procedure. You must never
repair or disassemble them ¢
.&..
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, refer to ¢
page 348, Finishing .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inter 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 trac­
tion on ice and snow.
.,. Use winter t ires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lowe r with winter tires
q ,&. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after installing wheels
¢page 327.
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 great ly as the tire ages, re­
gardless of the remaining tread .
A WARNING
-Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
332
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D 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
winter tires w ith the ~ symbol are permitted .
Snow chains
Snow cha ins not only improve the driving in win­
ter road condit ions, but also the braking.
.,. Only install snow chains on the
front wheels .
This applies a lso to vehicles with all wheel
drive* .
.,. 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 permitted speed when driv­
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi deale r 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 .

A WARNING ,~
Using incorrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acc i­
dent.
(D Note
Snow chains can damage the r ims/wheel cov­
ers* if the chains come into d irect contact
w ith them. Remove the wheel covers* before­
hand . Use coated snow chains.

Low aspect ratio tires
Your Aud i is facto ry-equipped with low aspect ra ­
tio ti res. These t ires have been tho rough ly tested
and been se lected specifically for yo ur model for
their superb per formance, road feel and handling
under a variety of driving conditions. Ask your au­
thorized Audi dealer for more details .
The low aspect ratio of these t ires is indica ted by
a numera l of
55 or les s in the tire's size designa ­
tion. The numeral represents the ratio of the
tire's sidewall height in r elation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more.
The performan ce of low-aspect- ratio tire s is par­
ticularl y sensiti ve to improper inf lat ion pres­
sure . It is therefore impo rtant that low aspect
ratio tir e s are infl ated to the specified pressu re
and tha t the inflation pr essure is regularly
checked and maint ained . Tire pre ssure s should
be check ed at lea st once a month and alwa ys
b efore a long trip<=:>
page 32 7.
What you can do to a void tire and rim
damage
L ow aspect rat io tires can be damaged more easi­
l y by impact with potho les, cu rbs, gull ies or
r idges on the road, pa rtic ularly if the tire is un­
derinflated.
Wh eel s
In order to min imize the occurrence o f impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau ­
t ions:
- Always maintain recommended inflation pres ­
sures . Check your tire pressure every 2,000
m iles (3,000 km) and add air if necessary .
- Drive carefully on roads with potholes, deep
gu llies or ridges . The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immed iate ly inspect your
tires or have them inspected by the nearest au­
thorized Audi dealer . Replace a damaged tire as
soon as possible .
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not always
easy to see . Damage can lead to loss of a ir and
underinflation, wh ich could eventually cause
tire fa ilu re . If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos­
sible.
= These tires may wear mo re quickly tha n others.
- Please also remember that , while these tires
de live r responsive ha nd ling, they may ride less
comfort ably and make more noise t han other
choices .
Reduced performance in w inter /cold season
conditions
All tires are des igned for certai n pu rposes. The
low aspect ratio, ultra high performance tires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance and handling. They are not suitable for co ld, snowy or
icy weather conditions. If you drive under those
c ircumstances, you should equip your vehicle
with all -season or winter tires, which offer better
tract ion under those conditions . We suggest you
use the recommended s now or a ll-season tires
spe cified for your vehicle, o r their equiva lent.
Refer
to <=:> page 332 for more detailed informa ­
t ion regard ing winter tires.

A 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
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 324. We recommend that you
use these tires.
Storing tire pressures
If the tire pressure changes or a tire is replaced,
it must be confirmed in the Infotainment sys­
tem .
.. Before storing the tire pressures, make sure the
tire pressures of all four tires meet the speci­
fied values and are adapted to the load
~page 327 .
.. Switch on the ignition .
.. Select in the Infotainment system:

~ The wheel bolt tightening specification must be
90
ft lbs (120 Nm). Check it as soon as possible
with a torque wrench . Drive carefully until then.
~ Have the faulty wheel replaced as quickly as
possible.
(D Tips
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing a
tire, they should be replaced before you
check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
Notes on wheel changing
Please read the information ¢ page 324 if you
are go ing to use a replacement tire which is dif­
ferent from the tires on your vehicle.
After you change a tire:
- Check the tire pressure on the replacement
tire immediately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or quali­
fied workshop.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lbs (120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
tightening torque.
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble . Remount the wheel cover.
Until then, drive with extra care and at reduced
speeds .
Emergency assistance
A WARNING
- If you are going to equip your vehicle with
tires or rims which differ from those which
were factory installed, then be sure to read
the information

-Always make sure the damaged wheel or
even a flat tire and the jack and tool kit are
p ro perly secured in the luggage compart­
ment and are not loose in the passenger
compa rtment.
- In an accident or sudde n maneuver they
could fly forward , injur ing anyone in the ve­
h icl e.
- Always store damaged wheel, jack and tools
securely in the luggage compartment. Oth­
erwise, in an acc ident or sudden maneuver
they could fly forward, causing injury to pas­
sengers in the ve hicle.
