Pre sense can initiate steps to protect vehicle oc­
cupants in certain dangerous situations. The
fu nctions described a re available depending on
ve hicle equi pment:
Audi pre sense basic
The fo llow ing funct ions can be triggered in cer­
tain driving situations:
- Tighten ing of the safety belts (for examp le,
during heavy braking): the front safety belts
have reversible belt tensioners. If a coll is ion
does not occur, the safety belts loosen slightly
and are ready to trigger again.
- Closing the w indows and the sunroof*
The function of the pre sense basic is activated at
a speed of 20 mp h (30 km/h) or higher. The de ­
p loyment time is adapted in the drive select dy­
namic mode.
Audi pre sense front (vehicles with adaptive
cru ise control*)
Pre sense front contains the f unctions of pre
sense basic. In add ition, the likelihood of a rear­
end collis ion with the vehicle ahead is also calcu­
lated, withi n the limits of the system. If the risk
of a collision is detected, the following functions
can t rigge r:
- Audi braking gua rd¢

Safety belts
General information
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety be lts are neces­
sary, how they work and how to adjust and wear
them correctly.
.. Read all the information that follows and heed
all of the instructions and WARNINGS.
&_ WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death.
- Safety belts are the s ingle most effective
means ava ilable to reduce the risk of serious
injury and death in automobile accidents.
For your protect ion and that of your passen­
gers, always co rrectly wear safety be lts
when the vehicle is moving .
- Pregnant women, injured, o r physically im­
paired persons must a lso use safety belts.
L ik e all vehicle occ upants, they are mo re
likely to be serio usly injured i f they do not
wea r safety be lts. The best way to protect a
fetus is to protect the mother -throughout
the ent ire pregnancy .
Number of seats
Your Audi has a total of five seating positions:
two in the front and three in the rear. In some
veh icles, there are four seating positions: two in
the front and two in the rear . Each seating posi­
tion has a safety belt .
&_ WARNING
Not wea ring safety belts or wearing them im­
properly incre ases the risk of ser io us personal
injury and dea th.
- Never st rap more tha n one person, includ­
ing small ch ild ren, into any be lt .
It is espe­
c ia lly da ngerous to place a safety belt over a
child sitting on your lap .

-Never let more people ride in the vehicle
than there are safety be lts available .
- Be s ure everyone riding in the vehicle is
properly restrained with a separate safety
be lt or ch ild restraint.
~ Safety belt warning light
Your vehicle has a warning system for the driver
and front seat passenger to remind you about the importance of buckling-up .

Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo­
ple riding in vehicles .
Fig. 221 Unbelted occupants in a vehicle heading for a wall
Fig. 222 The vehicle crashes into the wall
The physical principles are simple. Both the vehi­
cle and the passengers possess energy which var­ ies with vehicle speed and body weight. Engi­
neers call this energy "kinetic energy."
The higher the speed of the vehicle and the greater the vehicle's we ight, the more energy
that has to be "absorbed" in the crash.
Veh icle speed is the most significant factor. If
the speed doubles from 15 to 30 mph (25 to 50
km/h), the energy increases 4 t imes!
Because the passengers of this vehicle are not us­
ing safety belts
¢fig. 221, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall¢
fig. 222 .
Safety belts
The same p rinciples apply to people sitting in a
vehicle that is invo lved in a fronta l co llision. 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.
People who do not use safety belts are a lso not
attached to the ir vehicle. In a frontal collis ion
they will also keep moving forward at the speed
their vehicle was travelling 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 collisions .
What happens to occupants not wea ring
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!
Fig. 223 A dr iver not wearing a safety belt is violently
thrown forward
Fig . 224 A rear passe nger not wearing a safety belt will fly
forwa rd and strike the driver
Unbelted occupants are not able to resist the tre­
mendous forces of impact by holding tight or
bracing themselves . Without the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam v iolently into the steering wheel,

instrument panel, windshield, or whatever else is
in the way
r:!> fig. 223. This impact with the vehi­
cle interior has all the energy they had just be­
fore the crash.
Never rely on airbags alone for protection . Even
when they deploy, airbags provide only additional
protection. A irbags are not supposed to dep loy in
all kinds of accidents. A lthough your Audi is
equipped w ith airbags, all vehicle occupants, in­
cluding the driver, must wear safety belts cor­
rectly in order to minimize the risk of severe in­
jury or death in a crash .
Remember too, that airbags will deploy only
once and that your safety belts are always there
to offer protect ion in those accidents in wh ic h
airbags are not supposed to deploy or when they
have a lready deployed . Unbel ted occupants can
also be thrown o ut of the veh icle where eve n
mo re severe or fatal injuries can occur .
It is also important for the rear pass engers to
wear safety belts correctly. Unbelted passengers
i n t he re ar seats endanger no t on ly themse lves
but also the drive r and other passengers
~ fig . 224. In a frontal collision they will be
thrown forward violently, where they can hit and
in jure the driver and/or front seat passenger.
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision . It's simply
not true!
F ig . 22 5 Driver is co rrectly restrai ned in a sudde n brak ing
m aneu ver
Safety belts used properly can make a b ig d iffer­
ence. Safety belts help to keep passengers in
their seats, gradually reduce energy levels ap-
220
plied to the body in an accident , and help prevent
the uncontrolled movement that can cause seri­
ous injuries. In add ition, sa fety belts red uce the
danger of being thrown out of the vehicle.
Safety be lts attach passengers to the car and g ive
them the benefit of being s lowed down more
gently or "soft ly" thro ugh the "give" in the safety
belts, crush zones and other safety feat ures engi­
neered into today's vehicles. By "absorbing" the
k inet ic energy over a longer per iod of t ime, the
safety belts make the forces on the body more
"tolerab le" and less likely to cause inju ry .
Although these examples are based on a frontal
collision, safety be lts ca n also substantially re ­
duce the r isk o f injury in ot her kinds of crashes .
So, whethe r yo u're on a long trip or just goi ng to
the cor ne r store, a lways b uckle up and make s ure
othe rs do, too. Ac ciden t st at ist ics show that veh i­
cle o ccupants prope rly wearing safety bel ts have
a lowe r risk of being injured and a m uch better
chance of surviving an acc ident . Properly using
safety be lts also great ly increases the ability of
the supp lemental airbags to do their job in a col­
li sion. For this reason, wearing a safety belt is le­
gally required in most countries including much
of the United States and Canada .
Although your Aud i is equipped with airbags, you
still have to wear the safety belts provided. Front
airbags, for examp le, are activated only in some
frontal collisions. The front airbags are not act i­
vated in all frontal collisions, in side and rear co l­
li sions, in roll overs or in cases where the re is not
eno ugh deceler ation throug h impa ct to the front
of the vehicle . The same goes for the other a irbag
systems in your Audi. So, always wear your safety
belt and make sure everybody in your vehicle is
properly rest rained!
Important safety instructions about safety
belts
Safe ty belts must always be correctly positioned
acros s the strongest bones of your body .
.,. Always wear safety belts as illustrated and de ­
scribed in this chapter.
.,. Make sure that your safety be lts are always
ready fo r use a nd are not damaged .

"' " "' .... 0 0 :r A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death . Safety belts can work only
when used correct ly.
-Always fasten your safety belts correctly be­ fore driving off and make sure all passen­
gers are cor rect ly restrained.
- For maximum protection, safety belts must
always be posit ioned properly on the body .
- Never strap more than one person, includ­
ing small ch ildren, into any belt .
- Never place a safety belt over a child sitting
on your lap.
- Always keep feet in the footwell in front of
the seat wh ile the vehicle is being driven.
- Never let any person ride w ith their feet on
the instrument panel or sticking out the
window or on the seat .
- Never remove a safety belt while the vehicle
is moving . Do ing so will increase your risk of
being injured or k illed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable ob-
jects 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 hard­
ware.
- Do not wear the shoulder part of the belt
under your arm or otherwise out of position .
- Several layers of heavy clothing may inter­
fere with correct positioning of belts and re­
duce the overall effectiveness of the system.
- Always keep belt buckles free of anything
that may prevent the buckle from latching
securely .
- Never use comfort clips or devices that cre­
ate slack in the shoulder be lt . However, spe­
cial clips may be requ ired for the proper use
of some child restraint systems.
- Torn or frayed safety belts can tear, and
damaged belt ha rdware can break in an acc i­
dent. Inspect belts regularly.
If webbing,
bind ings, buckles, or re tractors are dam-
Safet y bel ts
aged, have belts rep laced by an authorized
Aud i dea ler or qualified workshop.
- Safety belts that have been worn and loaded
in an accident must be replaced with the
correct replacement safety belt by an au­
thor ized Audi dealer. Replacement may be
necessary even if damage cannot be clearly
seen. Anchorages that were loaded must al­
so be inspected.
- Never remove, mod ify, d isassemble, or try
to repair the safety belts yourse lf.
-Always keep the belts clean . Dirty belts may
not work properly and can impair the func­
tion of the inert ia reel

Safety b elt pr ete nsione rs
The safety be lts are equ ipped with a belt preten ­
sioner that helps to tighten the safety belt and
remove slack when the pretensioner is activated

Convertibl e loc king retra ctor
Every safety be lt except the one on the driver
seat is equipped with a convertible locking retrac­
tor that
must be used when the safety belt is
used to attach a child seat. Be sure to read the
important information about this feature
¢page 258.
A WARNING
Improperly pos it ioned safety belts can cause
ser ious injury in an accident¢
page 222,
Safety belt position.
- Safety belts offer optimum protection only
when the seatback is upright and belts are
prope rly positioned on the body.
- Never attach the safety belt to the buckle
for another seat. Attaching the belt to the
wrong b uck le wi ll red uce safety belt effec­
t iveness and can cause serious persona l in­
jury.
- A passenger who is not p roper ly restrained
can be serio usly injured by the safety be lt it­
self when it moves from the stronger parts
of the body into cr it ical areas like the abdo ­
men.
- Always lock the convertible lock ing retractor
when you are secur ing a child seat in the ve­
hicle ¢

A WARNING
Improperly positioned sa fety belts can cause
serious personal injury in an accident.
- The shou lder belt should lie as close to the
center of the collar bone as possib le and
should fit well on the body. Hold the belt
above the latch tongue and pull it evenly
across the chest so that it s its as low as pos­
sible on the pe lvis and there is no p ressure
on the abdome n. T he belt sho uld a lways fit
