Parking systems
General information
A ppl ies to: ve hicles w ith parking 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
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
¢page 147.
The rearview camera shows the area behind the
vehicle in the Infotainment system display. This display assists you when you are cross or parallel parking. The parking system plus functions are
also available ¢
page 148.
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 pay attention to the area around the
vehicle -us ing the rearview mirror, too.
-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
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
146
-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 this obstacle.
-Keep enough distance from the curb to re­
duce the risk of damage to the rims.
(D Tips
-T he 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 shou ld be good light and weath­
er conditions.
-You can change the volume and pitch of the
signals as well as the display¢
page 150.
-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 .

Intelligent Technology
- Press the accelerator pedal carefully when
acce le rating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and th is can affect driving stability and
increase the risk of a co llision . condition
. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de ­
scribed are working .
@ Tips
-The ABS and ASR only function correctly
when all four whee ls have a s imilar wear

Intelligent Technology
- Never let the vehicle roll while the engine is
stopped beca use this increases the risk of an
acc ident.
@ Note
- Never let the brakes "rub" by pressing the
pedal light ly when bra king is not actually
necessary. This causes the brakes to over­
h eat and inc reases bra king d istance and
causes wear .
- Befo re dr iv ing on a long stretch w ith steep

All wheel drive (quattro)
App lies to : vehicles wi th all w heel drive
In oil wheel drive, oil four wheels ore powered .
General information
In all wheel drive, the dr iv ing power is divided be­
tween all fou r whee ls . This happens autom atic al­
l y depending on yo ur driv ing beh avior as we ll as
the cur rent road conditions . Also see
c:> page 151, Electronic Stabilization Control
(ESC).
The all whee l drive concep t is designed for high
engine power. Yo ur vehicle is exce ptiona lly pow­
erfu l and has excellent driving cha racteristics
both under normal driving conditions and on
snow and ice. A lways read and follow safety pre­
cautions
c:> .&. .
Winter t ires
By using all whee l drive, your veh icle has goo d
forward motion with standard tires in winter con­
dit ions. However, using w inter or all season t ires
o n
all four wheels in the winter is recommended,
because th is w ill imp rove the
braking effect .
Snow chains
If there are s now chain laws, snow cha ins m ust
also be used on veh icles with all wheel drive
c:> page 342, Snow chains.
Replacing tires
Fo r vehicles wi th a ll w hee l drive, o nly wheels wi th
the same rol ling circ umfe rence sho uld be used .
Avoid using tires with different tread depths

Wheels
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily .
Rims
Rim s with a bolted r im 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
disassemble
them ¢_&. .
..&, 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 tightening specifi­
cation, see
¢ page 35 7, 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
¢ _&. .An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
¢ page 336.
342
The effectiveness of winter tires is reduced great­
ly when th e 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.
'
..&, 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
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 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 chains 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 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 inch (13 .5 mm) in height, includ­
ing the chain lock.
You must remove the snow chains on roads with­
out snow. Otherw ise, you could impair driving
ability and damage the tires.
~ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acc i­
dent.
0 Note
Snow chains can damage the rims/wheel cov­
ers * if the chains come into direct contact
w ith them. Remove the wheel covers * first.
Use coated snow chains.

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
tio tires. These t ires have been thoroughly tested
and been selected specifically for you r model for
their superb performance, road feel and handling
under a va riety of driving conditions. As k your au­
thorized Audi dealer for mo re de tails.
The low aspect ratio of these tires is indicated by
a numera l of
55 or less in the tire's size designa­
tion . The numeral represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more .
The performance of low-aspect-ratio tires is par­
ticularly sensitive to improper inflation pres­
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should
Wheels
be checked at least once a month and always
before a long trip
¢ page 336 .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi ­
ly by impact w ith potholes, curbs, gullies or
ridges on the road, particularly if the tire is un­
der inflated.
In order to minimize 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 miles (3,000 km) and add air if necessa­
ry.
-Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
-After any impact, immediate 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 a lways
easy to see. Damage can lead to loss of air and
unde rinflation, w hich could even tually cause
t ire fa ilure.
If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos­
sible.
-These tires may wear more quickly than others.
-Please also remember that, while these tires
deliver responsive handlin g, they may ride less
comfortably and make more noise than other
choices.
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. 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 cold, snowy or
icy weather conditions. If you drive under those
c ir cumstances, you should equip your vehicle

label, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
eq uipped w ith a t ire pressu re monitoring system
(TPMS) that illuminates a low tire press ure te ll­
tale when one or more of your tires is significant­ l y under- inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a s ignifi ­
cantly under- inflated tire causes the tire to ove r­
h eat and can lead to t ire failure. Unde r-inflation
a lso reduces fuel efficiency and tire tread life,
and may affec t the vehicle's handling and stop­
p ing ability .
P lease note that the TPMS is not a substitute for
p roper tire maintenance, and i t is the d rive r's re­
sponsib ility to ma inta in cor rec t tire p ressure,
even if under-inflation has not reached the leve l
to trigger illumination of the TPMS low tire pres ­
sure tellta le .
Your veh icle has also been eq uipped w ith a TPM S
mal funct ion indicator to indicate when the sys ­
tem is not operating properly . The TPMS ma l­
function indicator is combined with the low tire
pressure tellta le. When the system detects a
malfunct ion, the telltale will flash for approxi­
mately one minute and then remain cont inuously
i l lum inated . This sequence will continue upon
subseq uent ve hicle start-ups as long as the ma l­
function ex ists .
When the malfunct ion indicator is illuminated,
the system may not be ab le to detect or signal
low t ire press ure as intended. TPM S malf unctions
may occur for a var iety of reasons, including the
i nstalla tion of replacement o r alte rnate t ires o r
wheels o n the vehicle that prevent the TPM S
from func tioning properly. Always chec k the
TPMS malfunction telltale afte r rep lacing one or
more tires or whee ls on your ve hicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to cont inue to function
properly.
Wh eel s
If the tire pressure indicator appears
App lies to : vehicles wi th Tire Pressure Monito rin g Syste m in­

The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
U sing the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and vibration characterist ics of the ind ividu­
al tires. If the pressure changes in one or more
t ires, th is is indicated in the instrument cluster
display with an
[I] indicator light and a message .
If only one tire is affected, the location of that
t ir e will be indicated.

A WARNING
- If the tire pressure indicator appears in the
instrument cluster display, reduce your
speed immediately and avoid any hard
steering or braking maneuvers. Stop as soon
as possible and check the tires and their
pressures.
- The driver is responsible for maintaining the correct tire pressures. You must check the
tire pressures regularly.
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the pressure monitor indicator may
be delayed.
- Do not use run-flat tires on your vehicle. Us­
ing them when not permitted can lead to
vehicle damage or accidents.
@ Tips
- The tire pressure monitoring system can al­
so stop working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system in your
Audi was calibrated with "Audi Original
Tires"
¢ page 335. Using these tires is rec­
ommended .
- The tire pressure monitoring system can on­
ly monitor the tire pressure of the driving
tires. Check the tire pressure of the spare
wheel in the luggage compartment so that
if necessary it is ready for use.
