Airbag system
must be performed by qualified workshops
only. Make sure that any airbag service ac­
tion is entered in your Audi Warranty
&
Maintenance booklet under AIRBAG RE·
PLACEMENT RECORD .
-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al
-special handling may apply , see
www .dtsc.ca.gov/hazardouswaste/perchlo ­
rate . When the vehicle or parts of the re­
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regulations must be
observed . Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your 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
performs in a crash. For example, using tire-rim
comb inations not approved by Audi, lower ing the
vehicle, chang ing the stiffness of the suspension,
including the springs, suspension struts , shock
absorb ers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control 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 which it would not deploy if
the changes had not been made. Other kinds of
158
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it should .
& 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 suspension components that do not have the same performance charac­
teristics as the components origina lly instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Aud i.
Knee airbags
Description of knee airbags
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig . 155 Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel ¢
fig. 155, the
airbag for the passenger is at about the same height in the instrument panel underneath the
glove compartment.
The knee airbag offers add itional protect ion to
the driver's and passenger's knees and upper and lower thigh areas and supplements the protec­
tion prov ided by the safety belts .
If the front airbags deploy, the knee airbags also
deploy in frontal coll is ions when the deployment

Child safety
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. 165 Rear seat: child properly restrained in a booster
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 chi ldren 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
c>page 172.
Children up to at least 8 years old (over 40 lbs or
18 kg) are best protected in child safety seats de­
signed for their age and weight. Experts say that
the skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
176
must not use the vehicle safety belts without a
suitable child restraint .
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicable safety standards.
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the child's body in the right places. The routing of
the be lt over the child's body is
very important
for the child's protection, whether or not a boos­
ter seat is used. Children age 12 and under must
always ride in the rear seat.
Children who are at least 4
ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle 's
three point lap and shoulder belts. Never use the
lap belt portion of the vehicle's safety belt alone
to restrain any child, regardless of how big the
c hi ld is. Always remember that children do not
have the pronounced pelvic structure required for
the proper function of lap belt portion of the
ve­
hicle's three point lap and shoulder belts. The
child's safety absolutely requires that a lap belt
portion of the safety belt be fastened snugly and
as low as possible around the pelvis. Never let
the lap belt portion of the safety belt pass over
the child's stomach or abdomen.
In a crash, airbags must inflate within a blink of
an eye and with considerable force. In order to do its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­ pant
moves forward into the airbag .
A vehicle occupant who is out of position and too close to the airbag gets in the way of an inflating
airbag. When an occupant is too close, he or she
will be struck violently and will receive serious or possibly even fatal injury .
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any children, who must be in the front seat be­
cause of exceptional circumstances, be properly
restrained and as far away from the a irbag as
possible. By keeping room between the child's

" N .... 0 0 \,;J ' (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 dr iv in g a few feet, if necessary . Fol­
low the instructions from the manufacturer .
.. Note the maximum speed of 30 mph (SO km/
h). Note the loca l regulations.
Use of snow chains is only perm itted 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.
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 .
{[J) 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 air suspension*, be­
cause the vehicle height will be very low. If
Wheels
you drive with snow chains anyway, the
wheel housings and other vehicle compo­
nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch on sport
mode¢ page 120.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style . However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
Low -profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers , and
curbs . Therefore, it is particularly important to
maintain the correct tir e pressure
¢ page 211.
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 authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires .
Uniform tire quality grading
