CX) Parking
aids
General notes
Applies to: vehicles with rear parking aid/parking system
plus/park assist
Various systems are available to help you when
parking or manoeuvring in tight spaces, depend­
ing on the equipment fitted on your vehicle.
The rear parking aid gives an acoustic warning if
there are any obstacles behind the car
¢page 104.
When you are parking, the parking system plus
warns you acoustically and optically about obsta­
cles detected in front of and behind the vehicle
¢page 104. On vehicles with park assist, the
area detected at the side of the vehicle ®
¢page 104, Fig. 106 is also monitored.
The reversing camera uses the infotainment sys­
tem display to show a picture of the area behind
the vehicle captured by the camera. Orientation
lines in the image from the reversing camera as­
sist you when parking or manoeuvring
¢ page 106. In addition, you are assisted by the
functions of the parking system plus
¢page 104.
The park assist helps you to find suitable parking
spaces, to manoeuvre the vehicle into spaces par­
allel or perpendicular to the roadside and to drive
out of spaces parallel to the kerb ¢ page 108.
A WARNING
-Always watch the road and the area sur­
rounding the vehicle. The electronic systems
cannot replace the full concentration of the
driver. The driver is always responsible for
safety during parking and all other manoeu­
vres.
- Please note that certain surfaces, such as
clothing fabrics, cannot be detected or dis­
played by the system -risk of accident!
- The sensors and cameras have blind spots in
which neither people nor objects are regis­
tered. It is particularly important to ensure
that there are no small children or animals
near the vehicle -risk of accident! Parking
aids
- Impacts or damage to the radiator grille,
bumper, wheel arches or underbody can
cause misalignment of the sensors. This can
impair the effectiveness of the parking aids.
Have the systems checked by a qualified
workshop.
CD CAUTION
- The system may not always be able to de­
tect objects such as the following:
- Chains, trailer draw bars, posts or fences
- Objects above the sensors, such as wall
protrusions, etc.
- Objects with certain surfaces or struc­
tures, such as wire fences or powder snow
- As your car moves closer to low obstacles,
they may disappear from the sensors' field
of vision. Please note that you will no longer
be warned about these obstacles.
- Remember to maintain sufficient clearance
from the kerb to avoid damaging the wheel
rims.
(@ Note
- In certain situations, a warning may be giv­
en by the system even if there is no obstacle
within range of the sensors. This can be
caused by the following, for instance:
- Certain road surfaces or long grass
- External ultrasound sources, e.g. from
street cleaning vehicles
- Heavy rain or snow or dense exhaust
fumes
- To familiarise yourself with the system, we
recommend that you practise parking in a
quiet location or a car park. The weather
and light conditions should be good.
- You can adjust the volume of the beeps.
- There is a slight delay in the picture display.
- To ensure that the acoustic parking aid
works properly, the sensors must be kept
clean and free of snow and ice.

Park assist with 360°
display
Description
Applies to: vehicles with park assist
The park assist helps the driver to manoeuvre
the vehicle into and out of parking spaces.
Fig. 114 Diagram: Parking parallel to the roadside
Fig. 115 Diagram: Parking perpendicular to the roadside
The park assist helps you to find suitable parking
spaces, to manoeuvre the vehicle into spaces par­
allel or perpendicular to the roadside and to drive
out of spaces parallel to the kerb. The parking
space can be located between two vehicles or be­
hind one vehicle. The park assist takes over the
steering while the driver is parking the vehicle in
the usual way.
The parking system plus is an integral compo­
nent of the park assist c:::> page 10
4 and
helps you
during the parking manoeuvre.
The park assist sensors are located on the sides
of the front and rear bumpers. Please ensure that
the sensors are kept free of stickers, deposits and
any other substances which could impair the
function of the system. Notes on cleaning
c:::>page 263.
108 In
short parking spaces, the parking aid warning
tone will sound continuously when the vehicle is
less than approx. 0.20 m away from the obstacle.
Stop moving immediately!
A WARNING
- Please observe the safety warnings c:::> &. in
General notes on page 103.
- Please note that the park assist only han­
dles the steering. As the driver you are al­
ways responsible for braking and accelerat­
ing.
- It is the driver's responsibility to decide
whether a parking space shown in the dis­
play is suitable for the vehicle.
- The front of the vehicle swings out during
the parking manoeuvre. Please take all nec­
essary measures to ensure that other road
users are not endangered.
- The steering wheel turns rapidly on its own
when parking the vehicle and leaving the
space. Injury may result if a person reaches
between the spokes on the steering wheel
when it is turning.
CD CAUTION
- Please observe the safety warnings c:::>(j) in
General notes on page 103.
- In certain situations, the park assist will
guide the vehicle onto or across the kerb,
for instance if other vehicles are parked on
the kerb. You should always be ready to
take over the steering wheel in order to pre­
vent damage to the tyres and/or wheel
rims.
- Certain conditions in and around the park­
ing space can cause unexpected results
when parking.
- Ob j
ects such as pillars, posts, etc.
- Road surfaces such as loose gravel, snow,
ice, etc.

Wheels
Tyres and rims
General notes
� Inspect the tyres regularly for damage (cuts,
cracks or blisters, etc.). Remove any foreign
bodies embedded in the treads.
� If you have to drive over a kerb or similar obsta­
cle, drive very slowly and as near as possible at
a right angle to the kerb.
� Damaged rims or tyres must be replaced imme­
diately.
� Keep grease, oil and fuel off the tyres.
� Mark
the wheels before taking them off so that
they rotate in the same direction when refitted.
� When removed, the wheels should be stored
flat in a cool, dry and preferably dark place.
CD CAUTION
- Please note that summer and winter tyres
are optimised for the prevailing road condi­
tions at different times of year. We recom­
mend that you use winter tyres during the
winter months. At low temperatures, sum­
mer tyres lose their elasticity and grip, and
braking performance also suffers as a re­
sult. Cracks can form in the tread block on
summer tyres if they are used at very cold
temperatures, and this can cause perma­
nent damage to the tyres. An increase in
rolling noise and tyre imbalance may result
from this damage.
- Machined, polished or chrome-plated rims
must not be used in winter conditions. The
process used to manufacture these types of
wheel rim does not provide adequate sur­
face protection against corrosion, and the
rims can be permanently damaged by road
salt or similar.
New wheels or tyres
It is best to have all servicing of wheels and tyres
performed by a qualified workshop, since they
l l
COC = Certificate of conformity
254 have
the necessary special tools and replacement
parts in addition to trained personnel.
� New tyres do not yet give maximum grip. When
driving with new tyres, drive at moderate
speeds and be especially careful during the first
500 km.
� All four wheels must be fitted with tyres of the
same type, size (rolling circumference) and
preferably the same tread pattern.
� Tyres should be replaced in pairs and not indi­
vidually (i.e. both front tyres or both rear tyres
together).
� We recommend the use of Audi Genuine Tyres.
If you wish to use other tyres, please note that
the actual size can differ from the nominal size
marked on the tyre ¢ A .
� If you wish to purchase a different combination
of rims and tyres than the ones fitted on the ve­
hicle during production, it is advisable to con­
sult a qualified workshop beforehand ¢ A.
The sizes of the rims and tyres approved for your
vehicle are listed in the vehicle's documents (e.g.
EC Certificate of Conformity or COC document l)).
The vehicle documents vary depending on the
country in which the vehicle is registered.
If the spare wheel* is not the same type as the
tyres fitted on the car (for example if the car has
winter tyres or wide-section tyres) you should on­
ly use the spare wheel* if a puncture occurs, and
then only for a short period of time. In this case,
please drive with extra care. Refit a normal road
wheel as soon as possible.
On vehicles with four-wheel drive, all four wheels
must always be fitted with tyres of the same
type, make and tread pattern, as the driveline
could otherwise be damaged by variations in the
wheel speeds. For the same reason, only use a
spare wheel* which has the same rolling circum­
ference as the normal road wheels.
Manufacturing date
The manufacturing date is indicated on the tyre
sidewall (possibly only on the inner side of the
wheel): ..,.

means, for example, that the tyre was produced
in the 22nd week of 2016.
Audi Genuine Tyres
Audi Genuine Tyres with the marking "AO" are
specially matched to your Audi. When used prop­
erly, these tyres meet the highest standards in
safety and handling. Your specialist retailer will
be glad to provide more information.
_& WARNING
- Use only tyre/rim combinations and match­
ing wheel bolts approved by Audi. Otherwise
damage to the vehicle and an accident could
result.
- For technical reasons, it is not possible to
use wheels from other vehicles. In certain
cases, it is not even possible to use wheels
from another vehicle of the same model.
- It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not
rely entirely on the nominal tyre size
marked on the tyre; with some makes of
tyre the effective tyre size can differ signifi­
cantly from the nominal dimensions, even
though the tyres have the same size desig­
nation. Inadequate tyre clearance can result
in damage to the tyres or the vehicle, caus­
ing a serious safety risk.
-Avoid running the car on tyres that are more
than 6 years old. If you have no alternative,
you should drive slowly and with extra care
at all times.
- The use of run-flat tyres on your vehicle is
NOT authorised! Unauthorised use can cause
an accident or damage your vehicle.
- If wheel trims are fitted after the car is pur­
chased, ensure that there is an adequate
flow of air for cooling the brakes -risk of ac­
cident!
1} Please observe the applicable regulations in the country in
which you are travelling. Wheels
Tyre wear / damage
Fig. 221 Tyre tread: Tread wear indicators
Tyre wear
Inspect the tyres regularly for damage.
- The wear on under or over-inflated tyres is sig­
nificantly higher.
- Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
- If you notice excessive tyre wear, have the
wheel alignment checked by a qualified work­
shop.
- Have your tyres rebalanced if steering wheel vi­
brations indicate an imbalance. Otherwise, the
tyres and other parts of the vehicle may wear
faster.
Tread wear indicators
The original tyres on your vehicle have 1.6 mm
high tread wear indicators
¢ Fig.
221 running
across the tread at regular intervals. The letters
"TWI" or triangles on the sidewall indicate the
positions of the tread wear indicators.
The minimum tread depth 1
) is reached at the lat­
est when the tread is worn down to the tread
wear indicators. Replace the tyres with new ones
¢ _8..
Changing wheels round
Wheels should be changed round regularly to en­
sure that the wear is equal on all tyres. Fit the
wheels from the rear axle on the front axle and
vice-versa. All the tyres will then last for about
the same time.
255

Downloaded from www.Manualslib.com manuals search engine Wheels
On tyres with a directional tread pattern, note
the direction of rotation indicated on the sidewall
¢page 275.
Concealed damage
Damage to tyres and rims is often not readily visi­
ble. If you notice unusual vibrations or the car
pulling to one side, this may indicate that one of
the tyres is damaged. Reduce your speed imme­
diately. Inspect the tyres for damage. If no exter­
nal damage is visible, drive slowly and carefully
to the nearest qualified workshop and have the
car inspected.
A WARNING
Insufficient tread depth or different tread
depths on different wheels reduce safety. This
is particularly evident in vehicle handling,
when there is a risk of aquaplaning in deep
puddles of water and when driving through
corners. Braking is also adversely affected -
risk of accident!

Checking / adjusting the tyre pressures
"' Check the tyre pressures at least once a month
and, in addition, before starting a long journey.
.. The tyre pressures should only be checked
when the tyres are cold. The slightly raised
pressures of warm tyres must not be reduced.
.. Refer to the sticker ¢ Fig. 222 for the correct
tyre pressures according to the load the vehicle
is carrying.
.. If necessary, adjust the tyre pressure.

¢page 259.
"' Check the pressure of the spare wheel* /com­
pact temporary spare wheel*. Keep the spare
tyre inflated to the highest pressure approved
for the tyre.
A WARNING
Always adjust the tyre pressures to match
your driving style and the load the vehicle is
carrying.
- Excessive loads can cause you to lose control
of the vehicle -risk of accident!
- Under-inflated tyres flex more and can over­
heat at high speeds or when the vehicle is
carrying a heavy load. This could cause a
tyre blow-out and you could lose control of
the vehicle -risk of accident!
- Incorrect tyre pressures increase tyre wear
and adversely affect vehicle braking and
handling -risk of accident!
CD CAUTION
Replace any lost valve caps to prevent dam­
age to the tyre valves.

Wheel bolts and rims
Wheel bolts
The wheel bolts should be clean and turn easily.
A special adapter is required to turn the anti­
theft wheel bolts* cc> page 2 73.
Rims Rims with a bolted rim flange* or bolted trim
parts* consist of several components. A special
technique is applied to bolt these components
together. Never attempt to repair or dismantle
them c:::>A.
A WARNING
If the wheel bolts have not been tightened or
serviced correctly, they can come loose, and
you could lose control of the vehicle -risk of
accident! For the correct tightening torque,
refer to cc> page 2 75, A�er changing a wheel.
- Make sure that the wheel bolts and threads
in the wheel hubs are always clean and free
from grease.
- Only use wheel bolts that are designed to
match the rims on your car.
- Always have damaged rims repaired by a
qualified workshop. Never attempt to repair
or dismantle rims yourself -risk of accident!
Winter tyres
In winter road conditions winter tyres will consid­
erably improve the car's handling. Due to their
type of construction (width, rubber compound,
tread pattern), summer tyres give less grip on ice
and snow.
� Winter tyres must be fitted on all four wheels . Wheels
� Only use winter tyres of the correct type ap­
proved for your vehicle.
� Please note that the maximum permissible
speed for winter tyres may be lower than for
summer tyres cc>.&_ . Your specialist retailer can
advise you of the maximum speed for your
tyres.
� After fitting the wheels you must always check
the tyre pressures cc> page 256.
Winter tyres lose their effectiveness when the
tread is worn down to a depth of 4 mm. The per­
formance of winter tyres is also severely impaired
by ageing, even if the tread is still much deeper
than 4 mm.
A WARNING
- Never exceed the maximum approved speed
for your tyres. This causes the tyres to over­
heat and can even result in a blow-out -risk
of accident!
- Always adapt your driving style to the pre­
vailing road and traffic conditions. Drive
carefully and reduce your speed on icy or
slippery roads. Even winter tyres lose their
grip on black ice.
@ For the sake of the environment
Summer tyres should be fitted again as
soon
as possible; they give better handling on
roads which are free of snow and ice. They are
quieter, do not wear so quickly and reduce
fuel consumption.
(© Note
All-weather tyres can also be used instead of
winter tyres. Please note that winter tyres
with the£ symbol are required by law during
the winter season in some countries.

Snow chains will improve braking ability as well
as traction in winter conditions.
� Snow chains can be used on the front wheels
only. This also applies to vehicles with four-
wheel drive*.

... Check that the snow chains are correctly seated
after driving for a few yards; follow the instruc­
tions given by the manufacturer.
... Keep your speed below 50 km/h. Please ob-
serve the applicable local regulations.
For technical reasons snow chains may only be
used on tyres with certain wheel rim/tyre combi­
nations.
Rim size Rim offset Tyre size

You must remove the snow chains on roads which
are free of snow; otherwise the vehicle handling
may be impaired and the tyres may be damaged.
A WARNING
Unsuitable or incorrectly mounted snow
chains can cause you to lose control of the ve­
hicle -risk of accident!
CD CAUTION
- Snow chains can damage the rim/hubcap* if
they make direct contact with it. Remove
the hubcaps* beforehand. Use snow chains
which have a protective coating.
- If you use snow chains with links that pro­
trude more than 13.5 mm, this could cause
severe damage to the wheel housings and
other parts of the vehicle.
({D Note
When driving with snow chains, it may help to
switch on sport mode ¢ page 114.
Low-profile tyres
Applies to: vehicles with low-profile tyres
Your vehicle is fitted with low-profile tyres* as
standard equipment. Low-profile tyres have a
lower sidewall and provide a wider tread surface
and rim diameter than other wheel/tyre combi­
nations. This makes the car's handling more
agile. However, the ride may be less comfortable
on poor-quality roads and tracks, and rolling
noise may be louder.
258 Low-profile
tyres can be damaged more quickly
than standard tyres, for example by heavy jolts,
potholes, manhole covers, speed humps and
kerbs. It is therefore particularly important to
ensure that they are inflated to the correct pres­
sure c:>page 256.
Drive with particular care on poor-quality roads
to ensure that you do not damage the rims and
tyres.
Make sure to check your wheels regularly (every
3,000 km) for damage such as blisters/tears on
the tyre sidewalls or deformations/cracks on the
rims.
After a heavy jolt, or if any damage occurs, you
should have the rims and tyres checked and if
necessary replaced by a qualified workshop.
Tyre wear occurs more quickly on low-profile
tyres than on standard tyres.
Summer tyres are not suitable for cold condi­
tions, snow or ice. Use winter or all-season tyres
when driving in these conditions c:::> page 257.
Tyre pressure Loss
indicator
Tyre pressure loss indicator in instrument
cluster
Applies to: vehicles with tyre pressure loss indicator
The tyre pressure Loss indicator in the instrument
cluster informs the driver if the tyre pressure is
too Low or a system malfunction has occurred.
The tyre pressure loss indicator makes use of the
ABS sensors to compare the rolling circumfer­
ence and the vibration of the tyres. If changes in
the inflation pressure are detected on one or
more tyres, the driver is alerted by an indicator
lamp [tE and a message on the infotainment dis­
play. If only one tyre is affected, the display will
indicate its position.
Each time you change a tyre, change the wheels
round or change the tyre pressures on your vehi­
cle (e.g. when switching from partial load to full
load and vice-versa), you must store the new tyre
pressures on the infotainment system
c:::> page 259. Monitoring of the tyre pressures is
