178 Child Safety
Deactivating the convertible locking
retractor
The convertible locking retractor for child re­
straints will be deactivated automatically when the belt is wound all the way back into the retractor .
.,. Press the red button on the safety belt buck­
le. The belt tongue will pop out of the buck­
le .
.. Guide the safety 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 with­
out the convertible locking retractor for child
restraints.
If the convertible locking retractor should be
activated inadvertently, the safety belt must
be unfastened and guided completely back in­
to its stowed position to deactivate this fea­
ture. If the convertible locking retractor is not
deactivated, the safety belt will gradually be­
come tighter and uncomfortable to wear .
A WARNING
Improperly installed child safety seats in­
crease the risk of serious personal injury
and death in a collision.
- Never unfasten the safety belt to deacti­
vate the convertible locking retractor for
child restraints while the vehicle is mov­
ing. You would not be restrained and
could be seriously injured in an accident.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used

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 1 79
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 m inim ize the possibili­
ty of improper child restraint installation .
All chi ld 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 w ith
LATCH lower anchorages. Child
restra ints that are not equipped with the low­
e r ancho rage 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

Improper insta llation of child restraints
will increase the risk of injury and death in a crash.
- Always follow the instructions provided
by the manufacturer of the ch ild re­
straint you intend to install in your Audi.
- Improper use of child restra int anchors
(including tether anchors) can lead to in­
jury in a co llision. The anchors are de­
signed to withstand on ly those loads im­
posed by correctly fi tted ch ild restraints.
- Never mount two ch ild restraint systems
on one LA TCH lower anchor po int.
- Never attach two child rest ra int systems
to one tethe r strap or tether anchorage.

other items to the LATC H lowe r ancho­
rages o r to the tethe r ancho rs.
- If a tether or other strap is used to at­
tac h a child res traint to the front passen­
ger seat, make su re that it is not so
t igh t, that it causes the weight-sensing
mat to measure more weight than is ac­
t u ally on the seat.
- T he heav ier weight reg iste red 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 leave the child restraint with the
tether strap firmly installed for severa l
days, this cou ld leave a mark on the up­
holstery on the seat cushion and backrest
in the area where the tether strap was in­
s t alled. The upho lstery would a lso be per­
manently stretched around the tethe r

seats.
Using tether straps on rearward-facing
child restraints
Currently, few rearward-facing child restraint
systems come with a tether. Please read and h eed the child restraint system manufactur­
er's instructions carefully to determ ine how to
p roperly install the tethe r.

186 Intelligent technology
distance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinn ing and
transfers the d rive powe r to the other drive
wheel or whee ls if the vehicle is equipped with
a ll-wheel drive* . This function is not avai lab le
at higher speeds.
I n extreme cases , EDL automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating . EDL wi ll switch on again au­
tomatically when conditions have returned to
normal.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering torque.
In vehicles with dynam ic steeri ng*, ESC also
he lps to stabilize the stee ring in critical s itua­
tions.
Electronic interaxle differential lock* /
selective wheel torque control*
The electronic interaxle d ifferential lock (front
wheel drive) or the select ive wheel torque
con trol ( all wheel d rive) oper ates when driving
through curves . The front whee l on the inside
of the cu rve or both whee ls on the inside of
the curve are b raked se lectively as needed.
This a llows more prec ise driving in c urves. The
applicable system may not activate when driv­ ing i n wet or snowy conditions.
A WARNING
- The ESC and its integrated systems can­
not overcome the laws of physics. This is
especially important on slippery o r wet
roads . If the systems begin acting to sta·
b iliz e your veh icle, you s hou ld immed i­
a tely c ha n ge your speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will increase the risk of a loss of vehi­
cle control, collision and serious personal
inj uries.
-Always adapt your speed to road, traffic and weather conditions. The risk of los­
ing control of the vehicle increases when
d riving too fast, espec ially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead. The ESC a nd its integrated sys­
tems canno t always p reven t collisions -
there is still a risk of acc idents!
- Always accelera te wi th spe cial care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR only work cor rectly when
all four wheels are equipped with identi­
cal tires. D ifferent tire sizes can lead to a
reduction in engine power .
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator light
DJ or ml (USA
mode ls)l iiJ (Canada models) appears,
there may be a malfunction<=>
