Safety belts
Important safety instructions about safety
belts
Safety belts must always be correctly positioned
across the strongest bones of your body.
• Always wear safety belts as illustrated and de­
scribed 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 im­
properly increases the risk of serious personal
injury and death. Safety belts can work only
when used correctly.
- Always fasten your safety belts correctly be­
fore driving off and make sure all passen­
gers are correctly restrained.
- For maximum protection, safety belts must
always be positioned properly on the body.
- Never strap more than one person, includ­
ing small children, 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 while the vehicle is being driven .
- 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 vehicle is mov ing. Doing so will increase your risk of
being injured or killed.
- 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.
264
- 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 belt. However, spe­
cial clips may be required for the proper use
of some child restraint systems.
- Torn or frayed safety belts can tear, and
damaged belt hardware can break in an acci­
dent. Inspect belts regularly.
If webbing,
bindings, buckles, or retractors are dam­
aged, have belts replaced by an authorized
Audi dealer 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
thorized Audi dealer. Replacement may be
necessary even if damage cannot be clearly
seen. Anchorages that were loaded must al­
so 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 func­
tion of the inertia reel

Automatic safety belt retractors
Every safety belt is equ ipped with an automatic
belt retractor on the shoulder belt. Th is feature
locks the belt when the belt is pu lled out fast,
during hard braking and in an accident . T he belt
may a lso lock when you drive up or down a steep
hill or thr ough a s harp curve. Dur ing normal dr iv­
ing the bel t lets you move freely.

Important safety instructions for using
child safety seats
Correct use of child safety seats substantially re­
duces the risk of injury in an accident!
As the driver, you are responsible for the safety
of everybody in the veh icle, especially chi ldren:
~ Always use the right chi ld safety seat for each
child and a lways use it properly
~ page 297.
~ Always carefully follow the child safety seat
manufacturer's instructions on how to route
the safety belt properly through the child safe­
ty seat .
~ When using the vehicle safety be lt to install a
ch ild safety seat, you must first activate the
convertible locking retractor on the safety be lt
to prevent the child safety seat from moving
~page 302.
~ Push the child safety seat down with your fu ll
weight to get the safety be lt really tight so that
the seat cannot move forward or sideways
more than one inch (2.5 cm).
~ Secure unused safety belts on the rear seat
~ page 297.
Always remember: Even though your vehicle is
equ ipped w ith an Advanced A irbag system, all
children, especially those 12 years and younger,
should always ride i n the back seat properly re­
stra ined fo r their age and size.
_& WARNING
Not using a ch ild safety seat, using the w rong
child safety seat or improper ly installing a
Ch ild saf ety
chi ld restraint increases the risk of serious
personal injury and death.
- All vehicle occupants and especially children
must be restra ined properly whenever r iding
in a vehicle. An unrestra ined or improperly
restrained child cou ld be injured by striking
the inter ior or by be ing ejected from the ve­
hicle dur ing a sudden maneuve r or i mpact.
An unrest rained or imprope rly restrained
child is a lso at greater r is k of injury or death
through contact w ith an inflating airbag.
- Commerc ially availab le child safety seats
are requi red to comply with U.S. Federal
Motor Vehicle S afety S tandard (FMVSS) 213
(in Canada CMVSS 213).
- When buying a child restra int, select one
that fits your ch ild and the vehicle .
- Only use child restraint systems that fully
contact the flat portion of the seat cush­
ion. The ch ild restraint must not t ip or
lean to either side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames. They do not pro­
vide adequ ate cont act with the se at.
- Always heed all lega l requirements per­
t ai ning to the insta llation and use of child
safety seats and carefu lly follow the in­
structions provided by the manufact urer
of the seat you are using .
- Never a llow children under S7 inches
(1.45 meters) to wear a normal safety be lt.
They must a lways be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to the abdomen and
neck areas during sudden braking maneu­
vers or accidents .
- Never let more than one child occupy a chi ld
safety seat.
- Never let babies or o lder children ride in a
veh icle while sitting on the lap of another
passenger.
- Holding a child in your arms is never a sub­
stitute fo r a chi ld restraint system .
- The st rongest person cou ld no t ho ld the

The airbag on the passenger side makes the front
seat a potent ially dangerous place for a child to
ride. The front seat is not the safest place for a
child in a forward -fac ing child safety seat . It is a
very dangerous place for a n in fant or a larger
child in a rearward-facing seat .
_&. WARNING
Not using a child safety seat, using t he wrong
chi ld safety seat or imprope rly insta lling a
chi ld restraint increases the risk of ser ious
personal injury and death in a collision or oth­
er emergency situation.
- Ch ildren on the front seat of any car, eve n
wit h Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates .
A child in a rearward-fac ing ch ild safety seat
installed on the front passenger seat will be
serious ly injured and can be killed if the
front airbag inflates -even with an Ad­
va nced Ai rbag System .
- The inflat ing airbag will h it the ch ild safety
seat or infant carr ier with great force and
will smash the child safety seat and child aga inst the backrest, ce nter a rmrest, door
or roof.
- Always ins tall rear-fa cing c hild safety seats
on the rear seat .
- If you m ust instal l a rea rwa rd facing child
safety seat on the front passenger seat be­
cause of exceptional circ ums tan ces and the
PASSENGER AIR BAG OFF "1; light does not
come on and stay on, immediately insta ll
the rea r-facing child safety seat in a rear
seating position and have the a irbag system
inspected by your Audi dealer.
- The rear side of the ch ild safety seat shou ld
be positioned as close as possible to the
backrest on the veh icle seat. Adjust or re­
move the rear seat head restraint if it is dif-
f icult to instal l the ch ild seat with the head ._.

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 . 245 Rea r seat: chi ld p roper ly restrained in a booster
sea t
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 children 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 chi ld on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possib le and
must lie fla t 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
¢page 297.
Children up to at least 8 years old (over 40 lbs. or
18 kg) are best protected in chi ld safety seats de­
a ~ signed for their age and we ight. Experts say that
N ~ the skeletal structure, particularly the pelvis , of
g these children is not fully developed, and they
:E ' Child safety
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 applicab le 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 chi ld's body in the right places. The routing of
the be lt over the chi ld's body is very important
for the ch ild'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 ch ild, regard less of how big the
ch ild is. Always remember that child ren 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 shoulde r 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 pe lvis . 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 considerab le 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 pan t moves forward into the airbag .
A vehicle occ upant who is out of position and too
close to the a irbag gets in the way of an inf lating
airbag. When an occupant is too close , he or she
will be struck violent ly and w ill rece ive serious or
poss ibly even fata l injury .
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any ch ildren, who must be in the front seat be­
cause of exceptiona l circumstances, be properly
restrained and as far away from the airbag as
poss ible. By keeping room between the child's ..,_
