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 chi ld restraint on the vehicle
seat, Federa l reg ulations require specia l lower
anchorages in vehicles and dev ices on new
chi ld restraints to attach to the vehicle ancho
rages .
The combination of the tether anchorages and
the lower anchorages is now generally called
the
LATCH system for " Lower Anchorages and
T ethers for Children ."
F orward-facing child rest raints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply wit h new c hild
head movement performance requirements .
These new performance requirements make a tether necessary on most new chi ld seats.
I nstal ling a chi ld restraint that requi res a top
tether witho ut one can serio usly impair the
performance of the chi ld restraint and its ab il
ity to protect the c hild in a co llision . Installing
a child restraint that requires a top tether
without the top tether may be a v io lation of
state law.
Ch ild restra int manufacturers offer LATCH
lower anchorages on the ir ch ild seats with
hook -on or push-on connecto rs attached to
adjustable 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 .
Tether anchorage s
Your Audi Cabriolet is not equipped with a
LATCH system. It is not equ ipped with top
tether anchorages. It is equipped with lower
anchorages only.
Your Cabriolet is equipped with the Active Rollover Protection System, w hich is integrat-
Child Sa fet y 175
ed into the back rest of the rear seat . The Ac
tive Ro llover P rotection System dep loys up
wards to he lp prov ide addit ional protection in
certain co llisions and crash s ituations. For this
reason, your vehicle is
not equipped with top
tether anchorages for use with forward -facing
c hi ld restra ints.
In Canada , provinc ial law requ ires that for
ward-fac ing ch ild restraints use both top teth
er anchorages and lower anchorages; the re
fore, it is
not pos sib le to install a forward-fac
ing child restra int in this vehicle.
In the United States , child restraint installa
tion must conform w ith the child restraint
manufacture r's instructions. Check the in
structions that come w ith the c hild restra int
o r contact the ma nufactu rer to determine if
the ch ild res traint may be ins ta lled fac ing fo r
ward without sec uring the top te ther strap .
A WARNING ,..__
Improper installation of child restraints
will increase the risk of injury and death in
a crash.
- Always follow the instr uctions provided
by the manufacture r of the child re
straint yo u intend to install in your vehi
cle.
- Improper use of child restraint LATCH
lower anchorage points can lead to injury
in a collision. The LATC H lower anchorage
points are designed to wi thstand on ly
those loads i mposed by co rrectly fitted
child r est raints.
- Never mount two ch ild restra int systems
on one LATC H lower anchorage point.
- Never secure or attach any luggage or other item to the LATCH lower anchorag
es.
@ Tips
In other countries, the term "ISOFIX" is
used to describe the lower anchorages .

¢fig. 165.
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 .
All child restraints manufactured after Sep
tember 1, 2002, must have lower anchorage
attachments for the
LATCH system.
Remember that the lower anchorage points
are only 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 .
.&_ 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
and proper 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 WARNINGS
¢page 161,
Child Safety.

Installing a child restraint with LATCH
lower anchorages
Whenever you install a child restraint always
follow the child restraint manufacturer's in
structions.
F ig . 166 Lower anchorages: proper mounting
Mou nting
~ Make sure the seatback of the rear seat
bench is in the upright position and securely
latched in place.
~ Attach both hook-on connectors with the
spring catch release on the child safety seat
onto the LATC H lower anchorage so that the
connectors lock into p lace
c::> fig. 166 .
~Pullon the connector attachments to make
s u re they are properly attached to the LATCH
lower anchorage.
~ Pull straps tight following the child restraint
manufacturer's instructions.
Releasing
~ Loosen the te nsion on the straps following
the chi ld restraint manufacturer's instr uc
tions.
~ Depress the spring catches to re lease the
anchorage hooks from the lower anchorag
es.
Remember: Use tether straps to help keep the
child restraint firmly in p lace.
A WARNING
Improper use of the LATCH system can in
crease the risk of ser ious personal injury
and death in an acc ident.
Child S afety 177
- These anchors were deve loped only for
child safety seats using the "LATCH" sys
tem.
- Never attach other chi ld safety seats,
belts or other objects to these anchors.
- Always make sure that you hear a click
when latch ing the seat in p lace. If you do
not hear a click the seat is not secure and
could fly forward and hit the interior of
the vehicle, or be ejected from the veh i
cle .
A WARNING
Improper installat ion of ch ild rest ra ints
will increase the risk of injury in an acci
dent.
- Always follow the child restraint system
manufacturer's inst ruct io ns for prope r
installation of the ch ild restra int system
and proper use of te ther s traps as well as
the lower anchorages or safety belts in
your vehicle.

ty.
Using tether straps on rearward-facing
child restraints
-
Currently, few rearward-facing chi ld res traint
systems come w ith a tether . Please read and
heed the ch ild restraint system ma nufactur
er's instr uctions carefully to dete rmine how to
proper ly install the tether.
A WARNING
-
A child in a rearward-fac ing chi ld safety
seat installed on the front passenger seat
will be ser iously injured and can be killed if

186 Intelligent technology
to prevent excessive disc harge of the battery
and thus maintain starting capability.
Dynamic en ergy management
While the vehicle is be ing dr iven , dynamic en
e rgy management distributes the energy gen
erated accordi ng to the needs of the individu
a l components . It reg ulates cons umption, so
that more electrical energy is not being used
than is being generated and ensures an opti
mal state of charge for the battery.
@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are li mited .
- If starting ab ility is threatened, the indi
cator light(•) appears
¢ page 17.
What you should know
The highest priority is given to maintaining
starting capabili ty.
The battery is severely taxed in short-distance
d riving, in city traffic and during the co ld time
of year. Abundant e lectr ica l energy is re
qu ired, but only a little is generated. It is also
cr itical if the engine is not run ning and electri
cal components a re turned on . In th is in
stance energy is being consumed but none is be ing generated.
It is in precisely these situations that you w ill
notice energy management actively regulat
ing the distr ib ution of energy.
Vehicle stands for an extended period If yo u do not drive your vehicle over a period
of severa l days or weeks, electrical compo
nents are gradually cut back o r switched off .
This reduces energy cons umption and mai n
tains sta rting capab ility over a longer period .
Some of t he conve nien ce f unctions may no t
ope rate, su ch as the in ter io r l ights o r the
power seat ad justment. The convenience
f u nctions will be avai lable again when you
switch on the ignition and start the engine . With the engine turned off
If you
listen to the radio, for examp le, w ith
t h e engine t urned off or use other M MI func
tions, the battery is being discharged .
If s tarti ng capab il ity is jeopardi zed d ue to en
ergy consumptio n, the following warning ap
pears in the MM I display:
Pl ea se start the engine soon or the syst em
will be turned off .
The warning indicates that the system will be
tu rned off automatically after 3 minutes . If
you w ish to continue using the funct ions, yo u
have to sta rt the eng ine .
With the engine running
Althoug h electrical energy is generated when
the vehicle is being dr iven, the battery can be
come discharged. This happe ns mostly when
li ttle energy is being ge ne rated and a g reat
deal consumed and t he ba ttery's state of
c harge is no t opt imal.
To b ring the energy bala nce back into equ ili
br ium, consumers wh ich requ ire espec ially
lar ge amounts of ene rgy a re temporar ily cut
ba ck or sw itched off. Heat ing systems in p ar
t icu lar require a great deal of energy . If you
notice, for examp le, that the heated seats * or
the heated rear window are not heating, they
have been temporarily cut back or switched
off . These systems w ill be available again as
soon as the e nergy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T hi s is normal and not
a cause for concern. By increasing engine id le
speed the additional energy required is ge ner
ated and the battery is charged .

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam
age .
