Parking aid
General information
Ap plies to: vehicles with pa rk in g system plus/rearview cam­
era
Depending on your vehicle's equipment, various
parking aids will help you when parking and ma­
neuvering.
The
parking system plus assists you when park­
in g by aud ibly and visua lly indicating objects de­
tected
in front of and behind the veh icle
¢ page 143.
The rearview camera shows the area beh ind the
veh icle in the Infotainment system d isplay. The
l ines in the rearview camera image help you to
park or
maneuver ¢ page 145.
& 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 attent ion. The driver is always
responsible when enter ing 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 pay attention to the area around the
vehicle -using the rearview mirror, too .
-The sensors can be displaced by impacts or
damage to the radiator gr ille, bumper,
wheel housing and the underbody . The park ­
ing system may be impa ired as a result.
Have an authorized Audi dealer or author­
ized Audi Serv ice 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, vert ical poles or fences
-objects above the sensors such as wall ex ­
tensions
Parking aid
-objects with certain s urfaces 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 re­
duce the risk of damage to th e rims.
(I} Tips
-The system may provide a warning even
though there are no obstacles in the cover­
age area in some situations, such as:
-certa in road surfaces or when there is tall
grass
- external ultrasonic sources such as from clean ing vehicles
-in heavy rain, snow, or thick vehicle ex­
haust
-We recommend that you practice parking in
a traff ic -free location or parking lot to be ­
come fam iliar with the system . When doing
this , there shou ld be good light and weath­
er conditions .
-You can change the volume and pitch of the
signa ls as well as the display ¢
page 147.
-What appears in the infotainment display is
somewhat time-delayed .
-The sensors must be kept clean and free of
snow and ice for the parking aid to operate .

General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob ­
jects 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 in a cool, dry location
with as little exposure to light as
possible.
_&. 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
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
330
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
i n those seasons . Aud i recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
and braking ability. If summer
tires are used in very cold
temperatures, 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
t ions. The surface of the r ims
does not have sufficient corro­
sion protection for this and
could be permanently dam ­
aged by road salt or similar
substances.

Wheels
front and rear axles are the same
size¢&.
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly . To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have
approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 368.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden . Unusual vibrations in the
vehicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed .
340
.&_ WARNING
-Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can increase the risk of an
accident because it has a neg­
ative effect on handling, driv­
ing through curves, and brak­
ing, and because it increases
the risk of hydroplaning when
driving through deep puddles.
- Applies to: RS models: de­
pending on the equipment,
the widths of the standard
summer tires may be different
on the front and rear axles.
The wider tires are mounted
on the front axle. The tires
must not be rotated .

Wheels
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easi ly.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces . These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
d isassemble
them ¢_&. .
_& WARNING
Wheel bolts that are tig htened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
q page 364, After changing a
wheel.
- 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
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 trac­
tion 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 330.
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 341 .
346
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
@) 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 .
(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 with the
& symbol may be per­
mitted.
Snow chains
Snow cha ins not only improve the driving in win­
ter road conditions, but also the braking.
.,. Only install snow chains on the front wheels.
This applies also 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 speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authori zed 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 inch (13.5 mm) in height, includ­
ing the chain lock .
You must remove the snow chains on roads with­
out snow . Otherwise, you cou ld impair driving
ability and damage the tires .

u. 00 .-< N l'­ N .-< 0 N > 00
A 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.
@ Note
Snow chains can damage the rims/wheel cov­
ers* if the chains come into direct contact
with them. Remove the wheel covers* first .
Use coated snow chains.
(D Tips
When using snow chains, it may be useful to
switch on sport mode
¢page 149.
Low-profile tires
App lies to: ve hicles with low -profi le tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
la rger r im diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
L ow -profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole
covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire
pressure¢ page 341.
To reduce the risk of damage to the tires and rims, drive very carefully on poor roads.
Check your wheels regularly
every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility .
L ow -profile tires can wear out faster than stand­
ard tires.
Wheels
Uniform tire quality grading
- Tread wear
- Traction AA ABC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width
¢ page 331, fig. 275.
For example: Tread wear 200 , Traction AA, Tem­
perature
A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled cond it ion s on a specified
gov­
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driv ing habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA , A, Band
C. Those grades represent the tire's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
¢,& .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire
failure ¢,& .

Please read the info rmation c> page 33 7 if you
are going to use a spare tire which is different
from the tires on yo ur vehicle .
Afte r you change a tire:
-Check the tire pressure on the spare immedi­
ately after installation.
368
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- 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.
