134 Safety belts
-Failure to pay attention to the warning
light that come on, could lead to person
al injury.
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles.
Fig. 134 Unbe lted occupants in a vehicle heading for a
wall
Fig. 135 Th e vehicle crashes into the wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en
e rgy."
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash.
Vehicle speed is the most significant factor.
If
the speed doubles from 15 to 30 mph (25 to
50 km/h), the energy increases 4 times!
Because the passengers of this veh icle are not
using safety belts¢
fig. 134, they will keep
moving at the same speed the vehicle was
mov ing just before the crash, until something
stops them - here, the wall ¢
fig. 135.
The same principles apply to people sitting in
a vehicle that is involved in a frontal collision .
Even at city speeds of 20 to 30 mph (30 to 50
km/h), the forces acting on the body can
reach one ton (2,000 lbs, or 1,000 kg) or
more. At greater speeds, these forces are even
higher.
Peop le who do not use safety belts are also
not attached to their vehicle. In a frontal colli
s ion they will also keep moving forward at the
speed their vehicle was t ravell ing just before
the crash . Of course, the laws of physics don't
just apply to frontal collisions, they determine
what happens in all kinds of accidents and col
lisions .
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in
jured or killed. Always wear your safety belts!

Unbelted occupants are not able to resist the
tremendous forces of i mpac t by holding tight

Important safety instructions about
safety belts
Safety belts must always be correctly posi
tioned across the strongest bones of your
body.
,.. Always wear safety belts as illustrated and
described in this chapter.
,.. Make sure that your safety belts are always
ready for use and are not damaged.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death. Safety belts can
work only when used correctly .
- Always fasten your safety belts correctly
before driving off and make sure all pas
sengers are correctly restrained.
- For maximum protection, safety belts must always be positioned properly on
the body .
- Never strap more than one person , in
cluding small children, into any belt.
- Never place a safety belt over a child sit ting on your lap.
- Always keep feet in the footwell in front
of the seat while the vehicle is being driv
en .
- Never let any person ride with their feet on the instrument panel or sticking out
the window or on the seat.
- Never remove a safety belt while the ve
hicle is moving. Doing so will increase
your risk of be ing injured or killed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable
objects in or on your clothing, such as
eye glasses, pens, keys, etc., as these
may cause injury.
- Never allow safety belts to become dam
aged by being caught in door or seat
hardware .
- Do not wear the shoulder pa rt of the belt
under your arm or otherwise out of pos i
tion . -
Several layers of heavy clothing may in
terfere with correct positioning of belts
and reduce the overall effectiveness of
the system .
- Always keep belt buckles free of anything
that may prevent the buckle from latch
ing securely .
- Never use comfort clips or devices that
create slack in the shoulder belt . Howev
er, special clips may be required for the
proper use of some child restraint sys
tems .
- Torn or frayed safety belts can tear, and
damaged belt hardware can break in an
accident. Inspect belts regularly .
If web
bing, bindings, buck les, or retractors are
damaged, have belts replaced by an au
thorized Audi dealer or qualified work
shop.
- Safety belts that have been worn and
loaded in an accident must be replaced
with the correct replacement safety belt
by an authorized Audi dealer . Replace
ment may be necessary even if damage
cannot be clearly seen . Anchorages that
were loaded must also be inspected.
- Never remove, modify, disassemble, or
try to repair the safety belts yourself.
- Always keep the belts clean. Dirty belts
may not work properly and can impair
the function of the inert ia reel

Automatic safety belt retractors
Every safety belt is equipped w ith an automat
i c belt retractor on the shoulder be lt. This fea
ture locks the be lt when the belt is pulled out
fast, dur ing hard braking and in an accident.
The belt may also lock when you drive up or
down a steep hill or through a sharp curve. During normal driving the belt lets you move
freely.
Safety belt pretensioners
The safety belts are equipped with a belt pre
tensioner that helps to tighten the safety belt
and remove slack when the pretensioner is ac
tivated

-Safety belts offer optimum protection
only when the seatback is upright and
belts are properly posit ioned on the
body .
- Always make sure that the rear seat
backrest to which the center rear safety
belt* is attached is secu rely latched
whenever the rear cente r safety belt is
being used. If the backrest is not secu re
ly latched, the passenger will move fo r
ward with the backrest during s udden
braking, in a sudden maneuver and espe
cially in a crash.
- Never attach the safety belt to the buck
le for another seat. Attaching the belt to
the wrong buckle will reduce safety be lt
effectiveness and can cause ser ious per
sonal injury.
- A passenger who is not properly restrain
ed can be seriously injured by the safety
belt itself when it moves from the stron
ger parts of the body into cr itical areas
like the abdomen .
- Always lock the convertible locking re

Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries .
Wearing safety belts improperly can cause se
rious injury or death. Safety belts can only
work when they are correctly positioned on
the body . Improper seat ing pos itions reduce
the effectiveness of safety be lts and will
even
increase the risk of injury and death by mov
ing the safety be lt to crit ical areas o f the
body. Improper seating positions also in
crease the risk of serious injury and death
when an airbag dep loys and strikes an occu
pant who is not in the correct seating posi
tion. A driver is responsible for the safety of
all vehicle occupants and especially for ch il
dren . Therefore:
• Never permit anyone to assume an incorrect
sitt ing position in the vehicle while traveling
¢ _& .
_&. WARNING
Improperly worn safety belts increase the
risk of serious persona l injury and death
whenever a vehicle is being used.
- Always make sure that all vehicle occu
pants are co rrectly restrained and stay in
a co rrec t seating position whenever the
veh icle is being used.

Safety belt preten
sioners
How safety belt pretensioners work
In front, side ond rear-end collisions above a
particular severity and in o rollover, safety belts are tensioned automatically.
Reversible safety belt tensioners
The safety belts on the front seats are equip
ped with power reversible tensioners . The fol
lowing functions are available when the driv
er's/front passenger's safety belts are fas
tened:
- Automatic tensioners: at the start of a drive,
the safety belts automatically adjust to the
passenger after a certain time period or ve
hicle speed. To switch the automatic ten
sioners off, select the following in the
MMI:
I CAR ! function button > Car systems > Vehi·
cle settings
> Seats > Driver's seat or Pas·
senger's seat
> Automatic belt tensioner >
Off .
-In certain driving situations, the safety belts
may tighten with a reversible tensioning
function
c:> page 187 .
-The safety belts may also tighten with this
reversible tensioning function in minor colli
sions .
Pyrotechnic safety belt pretensioners
The safety belts are equipped with safety belt
pretensioners . The system is activated by sen
sors in front, side and rear-end collisions of
great severity and in a rollover . This tightens
the belt and takes up belt slack
c:> &. in Service
and disposal of safety belt pre tensioner on
page 141.
Taking up the slack helps to reduce
forward occupant movement during a colli
sion.
& WARNING
- It is possible for the pretensioners to de
ploy incorrectly.
- The pyrotechnic system can only provide
protection for one collision. If the pyro- technic
pretensioners deploy, the preten
sioning system must be replaced.
(D Tips
The pyrotechnic safety belt pretensioners
can only deploy once.
- The safety belt pretensioners do not de
ploy in minor frontal and side collisions,
in rear-end collisions, in rollovers and in
collisions involving very little impact
force.
- A fine dust is released when the pyro
technic safety belt pretensioners deploy.
This is normal and is not caused by a fire
in the vehicle.
- The relevant safety requirements must
be observed when the vehicle or compo
nents of the system are scrapped. A
qualified dealership is familiar with
these regulations and will be pleased to
pass on the information to you.
- Be sure to observe all safety, environ
mental and other regulations if the vehi
cle or individual parts of the system, par
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this
service for you.
Service and disposal of safety belt
pretensioner
The safety belt pretensioners are parts of the
safety belts on your Audi. Installing, remov
ing, servicing or repairing of belt pretension
ers can damage the safety belt system and
prevent it from working correctly in a colli
sion.
There are some important things you have to
know to make sure that the effectiveness of
the system will not be impaired and that dis
carded components do not cause injury or pol-
lute the environment. .,..
A WARNING ,~
Improper care, servicing and repair proce
dures can increase the risk of personal in
jury and death by preventing a safety belt pretens ione r from act ivat ing when needed
or act ivat ing it unexpe ctedly:
- The be lt pretensioner system can be acti
vated on ly once. If belt p retens ioners
have been act ivated, the system mus t be
replaced.
- Never repa ir, adjust, or change any parts
of the safety belt system.
- Safe ty belt systems includ ing safety be lt
pretensione rs cannot be repaired. Spe
ci al p rocedures are required for removal,
installation and disposal of this system.
- For any wor k on the safety belt sys tem,
we strongly recommend th at you see
yo ur authorized Audi dealer o r qualified
technician who has an A udi approved re
pair manual, training and specia l equip
ment necessary.
@ For the sake of the environment
Undep loyed airbag modu les and preten
sioners might be classified as Perchlorate Material -specia l hand ling may apply, see
www.dtsc.ca.gov/hazardouswaste/per chlorate. When the vehicle or parts of the

safety belts w ith pretens ioners are scrap
ped, all applicable laws and regulat ions
must be observed. Your autho rized Aud i
dea le r i s familiar w ith these requirements
and we recommend that you have your

Since the circumstances will vary considerably
between one collision and another , it is not
possible to define a range of veh icle speeds
that will cover every possible k ind and angle
of impact that will always trigger the airbags .
Important factors include, for example, the nature (hard or soft) of the object which the
car h its, the ang le of impact, vehicle speed ,
etc. The front airbags will a lso not inflate in
side or rear collisions, or in ro ll-overs .
Alw ays rememb er: Airbags will deploy only
once, and only in certa in kinds of collisions.
Your safety belts are always there to offe r pro
tect ion in those s ituations in which airbags
are not supposed to deploy , or when they have
a lready deployed ; for example , when your ve
hicle strikes or is struck by another vehicle af
ter the first co llision .
This is just one of the reasons why an a irbag is
a supp lementary restraint and is not a s ubsti
tute for a safety belt . The airbag system
works most effectively when used with the
safety belts. Therefore, always properly wear
your safety belts ¢
page 133.
A WARNING
Sitting too close to the steer ing whee l or
instrument panel will decrease the effec
tiveness of the airbags and will inc rease
the risk of pe rsonal injury in a co llision .
- Never sit closer than 10 inches (2S cm)
to the stee ring wheel or instr ument pan
el.
- If you cannot sit more than 10 inches
( 2 5 cm) from the steer ing whee l, investi
ga te whethe r adaptive equipment may
be available to help you reach the pedals
and increase your seating distance from
the steering wheel.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in
flates -even with an Advanced Airbag.
A irbag system 143
-To reduce the risk of injury when an air
bag inflates, always wear safety belts
properly ¢
page 136, Safety belts.
-Always make certain that ch ild ren age 12
or younger a lways ride in the rear seat. If
children are not properly restrained, they may be severe ly injured or killed when an
airbag inf lates .
- Never let ch ildren ride unrestra ined or
improperly restrained in the vehicle. Ad
just the front seats prope rly .
- Never ride with the backrest reclined .
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 124.
-Always sit upright with your back against
the backrest of your seat .
- Never p lace your feet on the instrument
panel or on the seat. Always keep both
feet on the f loor in front of the seat to
he lp preven t serio us in ju ries to the legs
and h ips if the airbag infla tes.
- Never recline the front passenger 's seat
to transport objects . Items can a lso
move into the area of the s ide a irbag or
the front a irbag du ring bra king or in a
sudden maneuve r. Obje cts near the air
bags can become projectiles and cause
in ju ry when an airbag inflates.
A WARNING
Airbags that have deployed in a crash must
be replaced.
- Use on ly original equipment airbags ap
proved by Aud i and installed by a trained
technician who has the necessary too ls
and d iagnost ic equipment to properly re
place any airbag in your vehicle and as
sure system effectiveness in a crash .
- Never perm it salvaged or recycled air
bags to be installed in your vehicle . •
