.... Important
safety notes on the front airbag
system
There are a number of safety points concerning
the airbag system which you should remember.
This will help to reduce the risk of injury in an ac­
cident.
Fig. 199 Minimum distance from steering wheel
A WARNING
- It is important for the driver and front pas­
senger to maintain a distance of at least
25 cm from the steering wheel or dash­
board ¢Fig. 199. The airbag system will not
be able to give the required protection if you
sit too close to the steering wheel or dash­
board. There is also a risk of injury if the air­
bags are inflated. Additionally, the front
seat position should always be adjusted to
the body size of the occupant.
- If you do not wear a seat belt, if you lean
forward or to the side, or are not seated cor­
rectly while the vehicle is in motion, you are
at greater risk of injury. Should the airbag
system be triggered in an accident there is
an even greater risk of injury.
- Never let a child travel on the front seat
without an appropriate restraint system. If
the airbag is triggered in an accident, the
child could sustain serious or fatal injuries
¢page 195, Child seats.
- Child seats in which the child faces the rear
of the car are located directly in the path of
the front passenger's airbag if it inflates. In
this case, the child could sustain serious or
fatal injuries if the airbag were to be de­
ployed. 0

- Airbag
system
- Applies to vehicles on which the front pas­
senger's airbag cannot be deactivated: Do
NOT use a rearward-facing child seat on
the front passenger's seat.
- Applies to vehicles with key-operated
switch for deactivating the front passeng­
er's airbag: Do NOT use a rearward-facing
child seat on the front passenger's seat
while the front passenger's airbag is ac­
tive. If you have no alternative but to use a
rear ward-facing child seat on the front
passenger's seat, the front passenger's
airbag must be deactivated beforehand via
the key-operated switch* ¢ page 211.
Make sure that the front passenger's air­
bag is reactivated by means of the key-op­
erated switch* as soon as the child seat is
no longer needed on the front passenger's
seat.
- Occupants sitting in the front of the car
must never carry any objects or pets in the
space between them and the airbags, or al­
low children or other passengers to travel in
this position.
- Do not cover or stick anything on the steer­
ing wheel hub or the soft plastic surface of
the airbag unit on the passenger's side of
the dashboard, and do not obstruct or modi­
fy them in any way. These parts should only
be cleaned with a dry cloth (or with a cloth
moistened with plain water). It is also im­
portant not to attach any objects such as
cup holders or telephone mountings to the
surfaces covering the airbag units.
- Any work on the airbag system or removal
and installation of the airbag components
for other repairs (such as repairs to the
steering wheel or removal of seats) must be
performed by a qualified workshop.

.... Wheels
and tyres
Wheels 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
have the necessary special tools and replacement
parts and trained personnel. Wheels
and tyres
... 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 ¢.&_
.
... 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 ¢.&_
.
On vehicles with four-wheel drive, all four wheels
must always be fitted with tyres of the same
type, make and tread pattern, as otherwise the
driveline can 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.
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.
Manufacturing date
The manufacturing date is indicated on the tyre
sidewall (possibly only on the inner side of the
wheel):
DOT ... 2214 ...
means, for example, that the tyre was produced
in the 22nd week of 2014.
Audi Genuine Tyres
Audi Genuine Tyres with the marking "AO" or
"RO" are specially matched to your Audi. When
used properly, 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 ef­
fective tyre size can differ significantly from
the nominal dimensions, even though the
tyres have the same size designation. Inade­
quate tyre clearance can result in damage to
the tyres or the vehicle, causing 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!
Tyre wear / damage
Fig. 219 Tyre tread: Tread wear indicators
l l
Please observe the applicable regulations in the country in
which you are travelling.
232 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. 219 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
¢ ,&..
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.
On tyres with a directional tread pattern, note
the direction of rotation indicated on the sidewall
¢page 247.
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.

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!
Tyre pressure

pressures
The correct inflation pressures for tyres fitted at
the factory and for the compact temporary spare
wheel* are specified on a sticker. The sticker
¢ Fig. 220 is on the end face of the driver's door.

If you intend to drive the vehicle with a partial
load, adjust the tyre pressures to the specified
setting (D. Should you wish to drive with a full
load, you must increase the tyre pressure to the
specified maximum @
¢.&,.
.
Checking / adjusting the tyre pressures
.. Check
the tyre pressures at least once a month
and, in addition, before starting a long journey. Wheels
and tyres
.. 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. 220 for the correct
tyre pressures according to the load the vehicle
is carrying.
.. If necessary , adjust the tyre pressure.
.. Vehicles with tyre pressure loss indicator*:
Store the new tyre pressures on the infotain­
ment system ¢ page 235 .
.. 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.
@ For the sake of the environment
Under-inflated tyres will increase the fuel con­
sumption.
@ Note
We recommend using the tyre pressure set­
ting (Dor@ for partial loads.
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,

and tyres
tread pattern), summer tyres give less grip on ice
and snow.
... Winter tyres must be fitted on all four 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¢.&_ . Your specialist retailer can
advise you of the maximum speed for your
tyres.
... After fitting the wheels you must always check
the tyre pressures ¢page 233.
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.
.&_ 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.
(Qj) 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
Snow chains will improve braking ability as well
as traction in winter conditions.
234 ...
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
7Jx17 47mm 225/50
Only use snow chains with fine-pitch links. The
links must not protrude more than 13.5 mm
from the tyres (including tensioner).
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.
.&_ 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.
Tyre pressure Loss

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
