Important safety instructions for using child
safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of every ­
body in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly :::>
page 215.
-Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat.
- When using the vehicle safety belt to install a child safety
seat , you must first activate the convertible locking
retractor on the safety belt to prevent the child safety
seat from
moving => page 220.
- Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety
seat to the front passenger seat, make sure that it is not
so tight that it causes the weight-sensing mat to
measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size .

/b, WARNING (continued)
-Always move the front passenger seat into the rearmost
position of the passenger seat's fore and aft adjustment range,
and as far away from the airbag as possible before installing
the child restraint.
- Always make sure that nothing prevents the front
passenger's seat from being moved to the rearmost position in
its fore and aft adjustment range.
- Always make sure that the backrest is in the upright posi­
tion.
• Always buckle the child safety seat firmly
in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a collision.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being

Child safety seats
Infant seats
Babies and infants up to about one year old and 22 lbs or
10 kg need special rearward-facing child restraints that
support the back, neck and head in a crash.

Infants up to about one year (22 lbs . or 10 kg) are best protected in
special infant carriers and child safety seats designed for their age
group. Many experts believe that infants and small children should
ride only in special restraints in which the child faces the back of the
vehicle. These infant seats support the baby's back, neck and head

in a crash. These child safety seats must never be used in the front
seat because of the risk of serious injury or death should the airbag
deploy in a
crash:::::, fig . 185.
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a crash.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat -even with an Advanced Airbag System.
A child will be seriously injured and can be killed when the inflating airbag hits the child safety seat or infant carrier with
great force and smashes the child safety seat and child against the
backrest, center arm rest, or
door:::::, page 189, "Child restraints on
the front seat
-some important things to know".
• Always install rear-facing child safety seats or infant carriers on
the rear seat.
• Never install a rear-facing child restraint
in the forward-facing
direction. Such restraints are designed for the special needs of
infants and very small children and cannot protect them properly
if the seat is forward-facing.
• If you must install a rearward facing
child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer.

Convertible child safety seats
Properly used convertible child safety seats can help
protect toddlers and children over age one who weigh
between 20 and 40 lbs. (10 and 20 kg) in a crash.

Booster seats
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. tall.
Fig. 187 Rear seat:
child properly
restrained in a booster
seat
The vehicle's safety belts alone will not fit most children
until they are at least 4 ft. 9 in. tall and weigh about 80 lbs.
(36 kgl. 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 child on a booster seat.
-Always position the shoulder portion of the safety belt midway over the child's shoulder.
-Always make sure that the shoulder portion of the safety
belt never rests against or across the child's neck.
-Always make sure that the child can properly wear the
lap portion of the belt low across the thighs or pelvis and
never over the stomach or abdomen.
Children up to about 40 lbs (18 kg) are best protected in child safety
seats designed for their age and weight. Experts say that the skel­
etal structure, particularly the pelvis, of these children is not fully
developed, and they should not use the vehicle safety belts
~ page218,fig.187.
Children who weigh more than 40 lbs. (18 kg) may generally use the
available three point combination lap and shoulder belts when they
sit on an appropriate booster seat. Be sure the booster seat meets
all applicable 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 child's body in the right places. The routing of the belt
over the child's body is very important for the child's protection .
This applies whenever a child uses the vehicle's safety belts, even
when the child is big enough to use them without a booster seat. Children age 12 and under should always ride in the rear seat .
Children should not ride in the front seat unless no other seating
position is available because crash statistics show that children are
better protected in the rear seat.
In a crash , airbags must inflate within a blink of an eye and with
considerable 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
pant moves forward into the airbag.
A vehicle occupant including a child who is out of position and too
close to the airbag gets in the way of an inflating airbag. When an
occupant is too close, he or she will be struck violently and will
receive serious or possibly even fatal injury .
In order for the airbag to offer protection, it is important that all
vehicle occupants, especially any children, who must be in the front
seat in exceptional circumstances, be properly restrained and as far
away from the airbag as possible. By keeping room between the _.,.

& WARNING
Rearward-facing child restraints:
• A child in a rearward-facing child safety seat installed on the
front passenger seat will be seriously injured and can be killed if
the front airbag inflates -even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center arm rest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
the Advanced Airbag when it must be suppressed causing serious or even fatal injury to the child.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
• If the PASSENGER AIR BAG OFF light does not come on and stay
on, immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer. •
Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer's instruc­
tions when installing a child restraint in your vehicle. To
activate the convertible locking retractor:
-Place the child restraint on a seat, preferably on the rear
seat.
-Slowly pull the belt all the way out.
-Route it around or through the child restraint belt path
=>& .
-Push the child safety seat down with your full weight to
get the safety belt really tight.
-Insert the belt tongue into the buckle for that seating
position.
-Guide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.
-You should hear a "clicking" noise as the belt winds back
into the inertia reel. Test the convertible locking retractor
by pulling on the belt. You should no longer be able to
pull the belt out of the retractor. The convertible locking
retractor is now activated.
-Make sure that the red release button is facing away from
the child restraint so that it can be unbuckled quickly.
-Pull on the belt to make sure the safety belt is properly
tight and fastened so that the seat cannot move forward
or sideways more than one inch (2.5 cm).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash.

the way back into the retractor.
- Press the red button on the safety belt buckle. The belt
tongue will pop out of the buckle.
- Guide the belt all the way back into its stowed position.
Always let the safety belt retract completely into its stowed position.
The safety belt can now be used as an ordinary safety belt without
the convertible locking retractor for child restraints.
If the convertible locking retractor should be activated inadvert­
ently, the safety belt must be unfastened and guided completely
back into its stowed position to deactivate this feature. If the
convertible locking retractor is not deactivated, the safety belt will
gradually become tighter and uncomfortable to wear.

Additional Information
What types of child restraint anchors are
available and hovv are they related to child
safety?
For years, child restraints have been installed using the safety belts
already present in every vehicle.
Since September 1, 1999, child restraint manufacturers have been
providing tether straps that attach the top of the child restraint to
the vehicles structure, on most of their forward-facing systems in order to comply with U.S. Federal regulations for child restraint
performance in a crash. Vehicle manufacturers are required to
phase -in tether anchorages for attachment of the tether strap in
their U.S. vehicles beginning September 1, 1999.
The combination of the tether anchorages and the lower anchor­ ages is now generally called the LATCH system for "Lower Anchor
and Tether for Children".
