Child Safety 173
A WARNING
Using the wrong child restraint or an im­
properly installed child restraint can cause
serious personal injury or death in a crash .
- Always make sure that the safety belt re-
tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat in place during normal driving or in a
crash.
- 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 crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright position and securely latched
into place and cannot fold forward. Oth­
erwise, the seatback with the child safety
seat attached to it could fly forward in
the event of an accident or other emer­ gency situation.

LATCH Lower
anchorages and tether
for children
Child Restraint System anchors and how
are they related to child safety
To provide a s impler and more pract icable way
to attach the child restraint on the vehicle
seat, Federal regu lations require special lower
anchorages in vehicles and dev ices on new
child restraints to attach to the vehicle ancho­
rages.
The combination of the tether anchorages and
the lower anchorages is now generally called
the
LA TCH system for "Lower Anchorages and
Tethers for Children ."
F orward-facing child restraints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply with new ch ild
head movement performance requirements .
T hese new performance requirements make a
tether necessary on most new child seats.
I nstalling a chi ld restraint that requires a top
tether without one can seriously impair the
performance of the chi ld restraint and its ab il­
ity to protect the child in a co llision . Installing
a child restraint that requires a top tether
without the top tether may be a v iolation of
state law.
Ch ild restraint manufacturers offer LATCH
lower anchorages on their ch ild seats with
hook -on or push-on connectors attached to
adj ustable straps.
In addition to the LATCH lower anchorages,
these child restraint systems usually require
the use of tether straps to help keep the child
restra int firmly in place .
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of inju ry and death in
a crash.
- Always follow the instructions p rov ided
by the manufacturer of the ch ild re-
Child S afety 175
straint you intend to install in your vehi­
cle.
- Never install a chi ld restraint without a
properly attached top tether strap if the
child restraint manufacturer's instruc­
tions require the top tether strap to be
used.
- Improper use of child restraint LATC H
lower anchorage points can lead to injury
in a collision . The LATC H lowe r anchorage
points ar e designed to withstand on ly
those loads imposed by correctly fitted
child restraints.
- Never mo unt two ch ild restra int systems
on one LATC H lower anchorage point.
- Never secure or a ttach any luggage or
o ther item to the LATCH lower anchorag­
es.
a) Tips
In Canada, the terms "top tether" with
"lower u niversal anchorages" (or "lower
universa l anchorage ba rs") are used to de­
scribe the sys tem.
- In other countries, the t erm " ISOFIX" is
used to describe the lower a nch o rages.

Lower anchorages secure the child restraint in
the seat without using the vehicle's safety belts. Anchorages provide a secure and easy­
to-use attachment and minimize the possibili­
ty of improper child restraint installation.
A ll child restraints manufactured after Sep­
tember 1, 2002, must have lower anchorage
attachments for the
LATCH system.
Remember that the lower anchorage points
are on ly intended for installation and attach­
ment of child restraints specifically certified
for use with
LATCH lower anchorages . Child
restraints that are not equipped with the low­
er anchorage attachments can still be instal- led in compliance with the child restraint
manufacturer's
instructions on using vehicle
safety belts .
A WARNING
-Improper use of LATCH lower anchorages
can cause serious personal injury in an ac­
cident.
- Always carefully follow the child re­
straints manufacturer's instructions for
proper installation of the child restraint
an d prope r use of the lower anchorages
or safety belts in your vehicle.
- Never secure or attach any luggage or
other items to the
LATCH lower ancho­
rages.
- Always read and heed the important in­
formation about child restraints in this
chapter and WARN INGS

Tether anchors and tether straps
Fig. 151 Tet her anchors: recess flaps behind the rear
seatbacks
T he te ther anchors for the rear seating posi­
tions are located in recesses in the rear win ­
dow shel f¢
fig. 151 .
A tether is a stra ight or V-shaped st rap that
attaches the top par t of a ch ild restrai nt to
special a nchorage po ints in the vehicle.
T he purpose of the tether is to reduce the for­
ward movement of the child rest raint in a
c rash, i n orde r to help reduce the risk of head
injury that cou ld be caused by strik ing the ve­
hicle inte rior.
Fo rward facing child restraints manufactured
after September 1, 1999, are requ ired by U.S.
federa l reg ulations to comply wi th ch ild head
movement pe rformance requi rements. These
new performance requirements make a tether
necessary on most new child safety seats .
A WARNING
Improper installation of child restra ints
will increase the r isk of injury and death in
a crash.
-Always follow the instr uctions provided
by the manufacturer of the child re­
straint you intend to install in your Audi.
- Improper use of child restraint anchors
(including tether anchors) can lead to in­
jury in a coll ision. The anchors are de­
signed to withstand only those loads im­ posed by co rrectly fitt ed child restraints.
- Neve r mo unt two child rest ra int systems
on one LATC H lower anchor point.
- Never attach two child restraint systems to one tether strap o r tethe r ancho rage .
-

1 78 Child Safety
-Never attach a tether strap to a tie-down
hook in the luggage compartment .
- Never use child restraint tether ancho­
rages to secure safety belts or other
kinds of occupant restraints.
- Never secure or attach any luggage or
other items to the LATCH lower ancho­
rages or to the tether anchors.
- If a tether or other strap is used to at­
tach a child restraint to the front passen­
ger seat, make sure that it is not so
tight, that it causes the weight-sensing
mat to measure more weight than is ac­
tually on the seat.
- The heavier weight registered can make
the Advanced Airbag System work as
though an adult were on the seat and de­
ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child.
-If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
Installing the upper tether strap on the
anchorage
Fig. 1S2 Tethe r strap: prope r routing and mounting
Installing the tether strap
.,. Release or deploy the tether strap on the
child restraint according to the child re­
straint manufacturer's instructions. .,.
Guide the upper tether strap
under the rear
head restraint co
fig. 152 (raise the head re­
straint if necessary).
.,. Tilt the recess flap up to expose the anchor
bracket.
.,. Attach the tether strap anchorage hook into
the opening of the tether anchorage.
.,. Pull on the tether strap hook so that the
spring catch of the hook engages .
.,. Tighten the tether strap firmly following the
child restraint manufacturer's instructions.
Releasing the tether strap
.,. Loosen the tension following the child re­
straint manufacturer's instructions.
.,. Depress the spring catch on the hook and re­
lease it from the anchorage.
(D Note
If you leave the child restraint with the
tether strap firmly installed for several
days, this could leave a mark on the up­
holstery on the seat cushion and backrest
in the area where the tether strap was in­
stalled. The upholstery would also be per­
manently stretched around the tether
strap. This applies especially to leather
seats .
Using tether straps on rearward-facing
child restraints
Currently, few rearward-facing child restraint
systems come with a tether. Please read and
heed the child restraint system manufactur­
er's instructions carefully to determine how to
properly install the tether .
A WARNING ~ -
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 Ad­
vanced Airbag System.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat ..,.

Tires and vehicle load limits
There are limits to the amo unt of load or
weight that any vehicle and any t ire can carry .
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overloading
can not only lead to loss of vehicle contro l,
but c an also damage import ant parts of the
vehicle and can lead to sudde n tire failure, in­
cluding a blowout and sudden deflation that
can cause t he veh icle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded . Vehicle load includes everybody
and everyth ing in and on the vehicle. These load lim
its are technically referred to as the
vehicle's
Gro ss Vehicle Weight R ating
("GVWR").
T he "GVWR" includes t he weight of the basic
vehicle , a ll f actory installed accessories, a f ull
tank of fuel, oi l, coo lant and other f luids plus
maximum load. The max imum load incl udes
the number of passengers that the vehicle is
intended to carry ("seat ing capac ity ") wi th an
assumed we ight of 150 lbs . (68 kg) for each
passenger at a designated seating posit ion
and the total weight of a ny luggage in the ve­
hicle. If you tow a trai le r, the we ight of the
t ra ile r hi tc h and the tongue we ight of the
l oaded tra iler mus t be include d as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating ("GAWR ") is
the max imum load that can be applied a t each
of the veh icle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weig ht Ra ting are listed on the
sa fety comp lian ce s ticke r label loca ted on the
driver's side B-pillar. Yo ur Audi has 4 seat ing
pos itions , 2 in the front and 2 in the rea r fo r
total seati ng capacity of 4. Each seating posi­
t ion has a seat belt c:>
page 129, Safety belts.
T he fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
t h at the total weight of whatever is being car­
ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue weight of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier tha n the sta ndard we igh ts assumed
mean that less we ight can be carried as lug­
gage.
