What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle , the driver as well as the driver's abili ­
ty to concentra te on the road withou t being dis­
tracted.
The driver is responsib le for the sa fety of the ve­
hicle and a ll of its occupants . If your ability to
drive is impa ired, safety risks for everybody in the
vehicle increase and you a lso become a hazard to
everyone else on the road ¢
,&.. There fore:
.. Do not let yourse lf be distracted by passengers
or by using a cellular telephone .
.. NEVER dr ive whe n your driving ab ility is im -
paired (by med ications, alcohol, drugs, e tc.) .

Automatic safety belt r etractors
Every safety be lt is equ ipped wi th an automatic
be lt retractor on the shoulder belt. Th is feature
l ocks the belt when the belt is p ulled out fast,
during hard braking and in an accident. The belt may also lock when you drive up or down a steep
h ill or through a sharp curve. During normal driv­
ing the belt lets you move freely .
Safety be lt pret en sioner s
The safety belts are equipped with a belt preten­
sioner that helps to tighten the safety belt and
remove slack when the pretensioner is activated
c:> page 269. The function of the pretensioner is
monitored by a warning light
c:> page 32.
Con vertible loc king retractor
Every safety belt exc ept the one on the driver
seat is equipped with a convertible locking retrac­
tor that
mu st be used when the safety belt is
used to attach a child safety seat. Be sure to read
the impo rtant information about this feature
c:> page 306.
A WARNING
Improperly posit ioned safety be lts ca n cause
ser ious injury in an accident

Safety belt position.
-Safety belts offer optimum protection only
when the seatback is upr ight and belts are
prope rly pos itioned on the body.
-Always ma ke sure tha t the rear sea t bac k­
rest to wh ic h t he cente r rea r safety be lt is
attached is secure ly latched whenever the
rear center safety belt is being used. If the
backrest is not securely latched, the passen­
ger will move forward with the backrest dur­
ing sudden braking, in a sudden maneuver
and especially in a cras h.
-Never attach the safety belt to the buckle
for another seat. Attaching the belt to the
wrong buckle w ill red uce safety belt effec­
t iveness and can cause serious personal in­
jury.
-A passenger who is not p roperly restrained
can be seriously in ju red by the safety be lt it­
self when it moves from the stronger par ts

Improperly worn safety belts
Incorrectly positioned safety belts can cause se ­
vere injuries .
Wearing safety belts improperly can cause seri­
ous injury or death . Safety belts can only work
when they are correctly pos itioned on the body .
Improper seating positions reduce the effect ive­
n ess of safety be lts and will even inc rease the
ris k of injury and death by mov ing the safety bel t
to cr it ica l areas of the body. Imp roper seating
positions also increase the risk of serious inj ury
and death when an airbag deploys and strikes an
occ upant who is not in the co rrect s eat ing posi­
tion . A driver is respons ible for the safety of all
vehicle occupants and espec ia lly for children .

Belt tensioners
How safety belt pretensioners work
Reversible safety belt pr etensioners
T he following fu nctions a re availab le w hen safety
bel ts w it h reversib le safety bel t tensione rs a re

- In ce rtain driving situations , the safety belts
may tighten w it h a reversib le tensioning func ­
tion ¢ page 120.
-The safety be lts may also tighten with this re-
versible tens ion ing f un ct ion in m ino r colli sions.
Pyrotechnic safety belt pretens ioners
Seat belts with pyrotechnic safety belt preten ­
sioners are tensioned automatically i n severe col·
lisions , depending on the circumstances . This
helps to reduce the fo rwa rd motion of the o ccu­
pants.
A WARNING
r-----
- I t is poss ible for the pretensioners to dep loy
incorrectly .
- Any wo rk on the tens ioner system o r remov­
al and installation of system components
for other repairs m ust be performed by a
qualified wor kshop.
- The pyrote chnic system can only provide
protection for one collision. If the py rotech­
n ic pretens ioners deploy, the pretensioning
system must be replaced .
(D Tips
- A fine dust is re leased when the pyrotechnic
safety belt pretensioners dep loy. This is no r­
ma l and is not caused by a f ire in the veh i-
cle.

-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 circ uit 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.
-I f the vehicle or the circuit interrupter is
scrapped, all app licab le safety precautions
must be followed .

Undeployed airbag modu les a nd 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 with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
m iliar with these requi rements a nd we recom­
mend t hat you have you r 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-r im
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the stiffness of the suspens io n,
in clud ing the spr ings, suspens ion str uts, shock
absorbers et c. 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 meas ured by
the sensors and prevent the airbag from deploy­
in g when i t should .
Airbag sys tem
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 persona l injury in a
crash.
- Never install suspension components that
do not have the same pe rformance charac­
teristics as the components o rigina lly ins tal­
led on your vehicle.
- Never use tire-rim combinations t hat have
not been approved by Audi.
