- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
dea ler· risk of an accident!
- If the veh icle or the circuit interrupter is
scrapped, all applicab le safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modu les and pretension ­
ers might be classified as Perch lorate 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
m iliar with these requirements and we recom­
mend that you have your dealer perform this
serv ice 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 t ire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, chang ing the st iffness of the suspens ion,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag senso rs and sent to the
electronic 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 which it would not deploy if
the changes had not been made. Other kinds of changes may reduce the force levels meas ured by
the sensors and prevent the airbag from deploy­ ing when it should .

A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim comb inations can
change Advanced Airbag performance and in­
crease the r isk of serious personal injury in a
crash.
- Never insta ll suspension components that
do not have the same performance charac­
ter istics as the components origina lly ins tal­
led on you r vehicle.
- N ever use tire-r im combinations that have
no t been approved by Aud i.
A WARNING
It ems stored between the safety belt buckle
and the center conso le can cause the sensors
in the buckle to send the wrong information
to the electronic contro l module and prevent
the Advanced A irbag System from working
proper ly.
- Always make sure that nothing can interfere
with the safety belt buckles and that they
are not obstructed.

front and side airbag.
- Always follow the manufacturer's instruc­
tions prov ided 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 restra int .
- Always make sure that the safety belt upper anchorage is beh ind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly pos i­
t ioned.
- Always make sure tha t noth ing p revents the
front passenge r'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 ­

Fig. 244 Rear seat: ch ild prope rly restrained in a booster
se at
The vehicle 's safety belts alone w ill not fit most
ch ildre n 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 ch ildren up so
that the safety belt will pass p roperly over the
stronger parts of their bodies and the safety be lt
can he lp protect them in a crash.
.,. Do not use the convertib le loc king re trac to r
when using the ve hicle's safety be lt to restra in
a child on a booster seat.
.,. The shoulder belt must lie as close to the cen­
ter of the chi ld'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 t he stomach or abdomen . Make sure the
belt lies flat and snug . Pu ll on the belt to tight­
en if necessary.
.,. If you must transport an o lde r child in a boos ­
ter sea t on the front passenge r seat, yo u can
use the safety belt height adjus tment to help
adjust the shoulder portion p roperly .
.,. Secure unused safety belts on the rear seat

crease the risk of serious personal injury and
death in an accident .
- Th ese anchors were deve loped only for child
safety seats using the "LA TCH" system.
- Never attach other child safety seats, belts
or other objects to these anchors .
- Always make sure that you hear a click when
latch ing the seat in place. If you do not hear
a click the seat is not secure and could fly
forward and hit the interior of the vehicle,
or be ejected from the vehicle .
.,&. WARNING
Improper installation of child restraints will
increase the risk of injury in an acc ident.
- Always follow the child restraint system
manufacturer's instructions for proper in­
stallation of the child restraint system and
proper use of tether straps as well as the
lower anchorages or safety belts in your ve­
hicle .

mation and WARNINGS about child safety
264 and the installation of child restraint sys­
tems
c> page 248, Child safety .
(D Note
On vehicles with power adjustable rear seats*
some crite ria must be observed when attach­
ing the child restraint using the
LATCH sys­
tem:
- To attach the ch ild restraint securely, the
seat must be moved to the farthest rear po­
sition, the seat height set to the lowest po­
sit ion and the head restraint must be ad­
justed to the vertical position.
- If a child safety seat is attached to one of
the rear seats, this seat must not be adjust­
ed using the power controls under any c ir­
cumstances. The
Entry assistance for this
seat must also be deactivated in the MMI

the rear seat can be damaged by the adjust­
ment process.
Tether anchors and tether straps
Fig. 251 Tether ancho rs: recess flaps behind the rear seat­
backs
The tether anchors for the two* /three rear seat­
ing positions are located in recesses in the rear
window shelf
c> fig . 251 . Vehicles with two rear
seat ing positions* are equipped with two tether
anchors .
A tether is a straight or V-shaped strap that at­
taches the top part of a chi ld restraint to special
anchorage points in the veh icle.
The purpose of the tether is to reduce the for­
ward movement of the child restraint in a crash,
in order to help reduce the risk of head injury

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra-
o tio tires. These t ires have been thorough ly tested co
~ and been selected specifically for your model for ,.....
~ their supe rb performance, road feel and handli ng 0 0 :c ' Wh eel s
under a var iety o f dr iv ing condit ions . Ask your au ­
thorized Audi dea le r for more detai ls.
T he low aspect rat io of t hese tires is indicated by
a nu meral o f
55 or less in the tire's si ze des igna­
tion . The n umera l represents the ratio of the
tire's sidewa ll height in relation to its tread width
expressed in percentage . Conve ntiona l tires have
a height/width ratio of 60 or more .
The performance of low-aspect- ratio tires is par­
ti cula rly sen siti ve to imprope r inflation p res­
sure. It is the refore important that low aspect
rat io tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at lea st once a month and always
before a long trip
¢ page 293 .
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
ly by impact w ith potho les, curbs, gullies or
ridges on the road, particularly if the tire is un­
der inflated .
In order to m in imize the occurrence of impact
damage to t he tires of yo ur vehicle , we recom­
me nd tha t you observe the following preca u­
tio ns:
- Always maintain recommended inflat ion pres­
sures. Check you r ti re pressu re every 2,000
m iles (3,000 km) a nd add air if necessary.
- Dr ive carefully on roads w it h potholes, deep
gullies o r ridges. The impact from dr iving
t hrough or over such obst acles can damage
your tires. Impac t with a cur b may also ca use
damage to your tires.
- After a ny impac t, im med iate ly inspect yo ur
t ires or have them inspe cted by the neares t au­
t horized A udi dealer. Replace a damaged tire as
soon as possible.
- I nspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see. Damage can lead to loss of air and
underinflation, wh ich could event ually cause
tire fa ilure . If you believe that a tire may have
been damaged, replace the tire as soon as pos­
sible .
- These tires may wear more quickly than others . .,.
