The
airbag system is not a substitute for the seat
belts.
When fully inflated, the airbags reduce the risk
of head or chest
injury.

front airbag for the front passenger is in the
dashboard above the glove box
^Fig.
229. The
locations of the airbags are marked with the
word "AIRBAG".
In conjunction with the three-point seat belts,
the front airbags give additional head and chest
protection for the driver and front passenger in
the event of
a
severe frontal collision

230 Front airbags in inflated condition
The driver's and front passenger's airbag are
trig­

gered in certain frontal collisions
^>Fig.
230. Fur­
ther airbag systems may also be triggered, de­
pending on the circumstances.
When the system is triggered, the airbags fill
with a propellant gas and open out in front of the
driver and front passenger
^>Fig.
230. In order to
provide the desired extra protection in an
acci­

dent, the airbags have to inflate extremely rapid­
ly (within fractions of
a
second). The fully de­
ployed airbags cushion the forwards movement
of the front occupants and help to reduce the risk
of injury to the head and the upper part of the
body.
Special openings in the airbag allow the gas to
escape at
a
controlled rate to restrain the for­
ward movement of the occupant's head and tor­

so.
Once the impact has been absorbed, the air-
bag deflates sufficiently for the front occupants
to see forward.

Airbag system
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.

25cm

Fig.
231 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
oFig.
231. 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. The front seats and head
restraints must always be positioned cor­
rectly for the height 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
267, 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.

- 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
rearward-facing child seat on the front
passenger's seat, the front passenger's
airbag must be deactivated beforehand via
the key-operated switch*
^>page
288.
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.

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.

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 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
•=> /\.
•
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
<=> /\.

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
document1)).

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.
Applies to vehicles with four-wheel drive: All four
wheels must always be fitted with tyres of the
same type, make and tread pattern, as the drive-
line could otherwise be damaged by variations in
the wheel speeds. For the same reason, only use
a spare wheel* which has the same rolling cir­
cumference 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): •

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.
Tyre wear / damage

A
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!

Fig.
252 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.
252 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
depth1)
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.

x)
Please observe the applicable regulations in the country in
which you are travelling.

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. 253 for the correct
tyre pressures according to the load the vehicle
is carrying.

•
If necessary, adjust the tyre pressure.
• Applies to vehicles with tyre pressure loss
indi­

cator : Store the new tyre pressures

^>page
311.
• Check the pressure of the spare
wheeLVcom-

pact temporary spare wheel*. Keep the spare
tyre inflated to the highest pressure approved
for the tyre.
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!
