perchlorate. When the vehicle or parts of the
restraint system including a irbag modules
and safety belts with p retensioners are scrap·
ped, a ll applicable laws and regu lations must
be observed. Your a uthorized Audi dealer is
familiar w ith these requirements and we rec
ommend that you have yo ur dealer perform
this service for you .
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System pe rforms in a crash. For examp le, using tire-r im
comb ina tions not approved by Audi, lowering the
veh icle, chang ing the s tiffness of the suspens ion,
including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit . Some suspension changes
can, for example, increase the force levels meas
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made . Other ki nds of
changes may reduce the fo rce levels measured by
the sensors and preven t the airbag from deploy
ing when i t should.
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in
crease the risk of serious personal injury in a
crash.
-Never install suspens ion components that
do not have the same performance charac
teristics as the components originally instal
led on your veh icle.
-Never use tire-rim combinations that have
not been approved by Audi.
Airbag system
A WARNING
Items stored between the safety belt buckle
and the center console can cause the sensors i n the buckle to send the w rong information
to the electronic control modu le and prevent
the Advanced A irbag System from wo rking
p roperly.
- Always make sure that nothing can interfe re
with the safety belt buckles and that they
are not obstructed.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants.
F ig . 233 Dr ive r's knee airbag
T he driver knee airbag is in the ins trument panel
u nderneath the steer ing
whee l~ fig. 233, the
airbag fo r the passe nger is at abou t the same
height in the instr ument pane l underneath the
glove compartment.
The knee airbag offers add itional protection to
t h e driver 's and passenger's knees and uppe r and
lower thigh areas and supplements the protec
t ion prov ided by the safety be lts .
If the front airbags deploy, the knee airbags also
deploy in frontal collis ions when the deployment
threshold stored in the control unit is met

- Always read and heed all WARNINGS when
ever using a child restrained in a vehicle is
being used
c:> page 219, Safety belts,
¢ page 22 7, Airbag system and
¢ page 249, Important information.
A WARNING
If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety and
well-being require that the following special
precautions be taken:
- Make sure the forward-facing seat has been
designed and certified by its manufacturer
for use on a front seat with a passenger
front and side airbag .
- Always follow the manufacturer's instruc
tions provided with the child safety seat or infant carrier.
- Always move the front passenger seat to
the highest position in the up and down ad
justment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as far away from the air bag as possible, before installing the for
ward-facing child restraint.
-Always make sure that the safety belt upper anchorage is behind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly posi
tioned.
- Always make sure that nothing prevents the
front passenger's seat from being moved to
the rearmost position in its fore and aft ad
justment range.
-Always make sure the backrest is in an up
right position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
- If the light does not stay on, perform the
checks
c:> page 2 3 7, Monitoring the Ad
vanced Airbag System.
Child safety
- Take the child restraint off the front passen
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on whenever
the ignition is switched on.
Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and 80
lbs . (18 kg and 36 kg) who are less than 4
ft . 9
in . (57 inches/1 .45 meters) tall.
Fig. 243 Rear seat: c hild properly restrain ed in a boos ter
seat
The vehicle 's safety belts alone will not fit most
children until they are at least 4 ft . 9 in. (57 in
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
" Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a booster seat.
"The shoulder belt must lie as close to the cen
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen. Make sure the
belt lies flat and snug . Pull on the belt to tight
en if necessary.
"If you must transport an older child in a boos
ter seat on the front passenger seat, you can
use the safety belt height adjustment to help
adjust the shoulder portion properly.
" Secure unused safety belts on the rear seat

low the instructions from the manufacturer.
~ Note the maximum speed of 30 mph (SO km/
h). Note the loc al 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 .
You must remove the snow chains on roads with
out snow. Otherwise, you could impair driving
ability and damage the tires.
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.
0 Note
-Snow chains can damage the rims/wheel
covers* if the chains come into direct con·
tact with them . Remove the wheel covers*
first. Use coated snow chains.
-Using snow chains that add more than 0.4
inch (10.5 mm) of height can severely dam
age the wheel housings and other vehicle
components.
-Do not install and use snow chains if there is
a malfunction in the adaptive air suspen
sion, because the vehicle height will be very
low. If you drive with snow chains anyway,
the wheel housings and other vehicle com ponents can be severely damaged.
@ Tips
When using snow chains, it may be useful to
switch on sport mode
¢ page 128.
Low-profile tires
Appl ies to: ve hicles w ith low-profile tires
Your vehicle is equipped with low-profile tires* at
the factory . Compared to other tire/rim combina
tions, low-profile tires offer a wider tread surface
and a larger rim diameter with shorter tire side-
Wheels
walls. This results in an agile driving style. How
ever, it may reduce the level of comfort and in
crease road noise when driving on roads in poor
condition.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, speed
bumps and curbs. Therefore, it is particularly im
portan t to maintain the correct tire pressure
¢ page 293.
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 authori zed Audi
Service Facility.
Low-profile tires can wear out faster than stand
ard tires.
Summer tires are not suitable for cold weather,
snow or black ice. If you are driving in these con
ditions, use winter or all season tires
