Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
passenger can be locked with the convertible
locking re tractor to properly secure child
safety seats.
The safety belts emergency locking retractors
for the rear seats safety belts and for the
fro nt passenger's seat safety belt have a con­
vertible locking retracto r for child restra ints .
The safety belt must be locke d so that belt
webbing can not unreel. The ret ractor ca n be
activ ated to lock the safety be lt and p revent
the safety belt webbing from loosening up
d ur ing normal driv ing . A child sa fe ty seat can
on ly be proper ly installed whe n the safety belt is loc
ked so that the chi ld and child sa fety
seat wi ll stay in place.
Alw ays remember: Even tho ugh yo ur vehicle is
equipped wi th an A dvan ced Airbag system, all
c hi ldren, especially those 1 2 years and young ­
er, sho uld always ride in the back seat prope r­
l y restra ined fo r the ir age and size.
A WARNING
Improperly installed ch ild safety seats in­
crease the risk of serious personal injury
and death in a co llision.
- Always make sure that the safety belt re­
tractor is locked when insta lling a child
safety seat. A n un locked safety belt re­
trac to r cannot hold the child safety seat
in place dur ing norma l driving o r in a
crash.
- Always buckle the child safety seat firmly
in place even if a ch ild is not si tt ing in it.
A loose child sa fe ty se at can fly aroun d
du ring a s udden stop or in a collision .
- Always make sure that the rear seat
backres t to wh ich the center rear safety
belt is attached is securely latched when ­
eve r the rea r center safety belt is being
used to secure a ch il d restra int .
- If the backrest is not securely la tc h ed,
the child and the child restraint will be
thrown forward together with the back­
rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.
- Never install rear-facing child safety
seats or infant ca rr ie rs o n the front pas­
senger seat . A child will be serious ly in­
jured and can be killed when the passen­
ge r airbag inflates.
- The infla ting airbag will h it the ch ild
safety seat or infant carrie r w ith gr eat
for ce and will smas h the child safe ty seat
a nd child ag ai nst t he back res t, cen ter
a rmrest, doo r or roof.
- Always inst all rear-fa cing ch ild safety
se ats or in fa nt c arrie rs on the re ar se at.

-Forward-facing child safety seats or in­
fant carriers installed on the front pas­
senger's seat may interfere with the de­ ployment of the airbag and cause serious
injury to the child.
- It is safer to install a forward-facing
child safety seat on the rear seat .
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used

seat -some important things to know.
A WARNING
-
Always take special precautions if you
must install a forward or rearward-facing
child restraint on the front passenger's
seat in exceptional situations:
- Whenever a forward or rearward-facing
child restraint is installed on the front
passenger seat, the
PASSENGER AIR
BAG OFF light must come on and stay on
whenever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, perform
the checks described
c> page 163, Moni ­
toring the Advanced Airbag System .
-Take the child restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on.
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child.
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis-

tered by the weight-sensing mat and can
cause injury in a crash.
A WARNING
Forward-facing child restraints:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward-facing child re­
straint up, against or
very near the in­
strument panel.
- Always
move the passenger seat into its
rearmost position in the seat 's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the forward-facing child restraint . The
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
A 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
armrest, door or roof .
- Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances .
- A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure
on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air­
bag System. The heavier weight regis­
tered can make the system work as •

now be used as an ordinary safety belt with ­
out the convertible locking retractor for child
restra ints.
I f the convertible locking retractor shou ld 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 convertib le 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 ser ious personal injury
and death in a collision.
- Never unfasten the safety belt to deacti­
vate the convert ible lock ing ret ractor for
c hild restraints while the veh icle is mov­
ing. You would not be restrained and
cou ld be ser iously injured in an accident.

LATCH Lower
anchorages and tethers
for children
Child Restraint System anchors and how
are they related to child safety
To provide a s imp le r and more pract icable way
to attach the ch ild res traint on the veh icle
seat, Federa l regu lations require specia l lower
anchorages in vehicles and devices 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
LA TCH system for "Lower Anchorages and
T ethers for Children."
F orward- facing child restraints manufactured
after September 1, 1999, are required by U.S.
Child Sa fet y 189
federa l reg ulations to comply with new child
head movement performance requirements.
These new performance requirements make a
tether necessary on most new child seats.
Installing a ch ild restra int that requires a top
tethe r without one can seriously impair the
performance of the c hild restra int and its abil ­
ity to protect the child in a collis ion. Insta lling
a child restraint that requires a top tether
without the top tether may be a violat ion of
state law.
Child restraint manufacturers offer LATCH
lower anchorages on their child seats with
hook-on or push-on connectors attached to
adjustable straps.
In add ition to the LATCH lower anchorages,
these child restraint systems usually require
the use of tether straps to help keep the ch ild
restraint firmly in place.
A WARNING
Imp roper installat ion of child restra ints
will increase the r isk of injury a nd death in
a cr ash.
- Always follow the instr uctions provided
by the manufa cture r of the child re­
s traint yo u intend to install in your vehi­
cle.
- Never inst all a child restraint withou t 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 rest raint LATCH
lowe r ancho rage points can lead to injury
in a collision. The LATCH lower anchorage
points are designed to withstand on ly
those loads imposed by correctly fitted
child restraints.
- Never mount two child restra int systems
on one LATCH lower anchorage point.
- Never secure or attach any luggage or
other item to the LATCH lower anchorag-

@ Tips
- In Canada, the terms "top tether" with
"lower universa l anchorages" (or "lower
universal anchorage bars") are used to
describe the system.
- In other countries, the term "ISO FIX" is used to describe the lower anchorages .

Lower anchorages secure the child res train t 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 ch ild restra int installation.
All child restraints manufactured after Sep ­
tember 1, 2002 , must have lower anchorage
attachments for the
LATCH system.
Remember that the lower anchorage po ints
are o nly intended for installation and attach ­
ment of child restraints specifically certified
for use with
LATCH lower anchorages. Chi ld
rest raints that are not equipped with the low­
er anchorage attachments can still be insta l­
led in compliance with the child restraint
manufacturer 's instructions on us ing vehicle
safety belts .
Ln._ WARNING
-Improper use of LATCH lower anchorages
can cause serious personal injury in an ac­
cident.
- Always carefu lly 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 l uggage or
other items to the
LATCH lower ancho ­
rages .

child restraint manufacturer's instructions .
.,. Push down on the seat cushion so that the
lower anchorages are v isible .
.,. Pull off the gu idance fixtures from the low ­
er anchorages .
.,. Always remove the guidance fixtures and
keep them in a safe p lace when not in use.
You may find it easier to install ch ild re­
stra ints equipped with hooks attached to
straps without the guidance fixtures in place .
If this is the case, remove the guidance fix­
tures by pulling them off the anchorages. However , the guidance fixtures can help you
to locate the
LATCH anchorages.
A WARNING
Improper use of tether anchorages or low­
er anchorages can cause serious personal injury in a crash .
- Always carefully follow the child re­ straint manufacturer's instructions for proper insta llation and use of child re­
straint systems.
- Never use the
LATCH or tether anchorag­
es to attach safety belts or other k inds of
occupant restra ints .
- Ch ild restraint tether attachments and
lower attachments are only designed to
secure a ch ild restraint that has been
equ ipped to use these a ncho rages.
- Tethe r anchorages and lower anchorages
are designed to withstand only those loads imposed by correc tly fitted child
restraints. Under no ci rcumstance s can
they be used safely for adult or child
safety belts or harnesses .

192 Child Safe ty
- Never mount more than one chi ld re­
straint to a single tether or to a lower an­
chorage point. Attaching two child re­
straints to a single anchorage point can cause the anchorage to fail and cause se­
rious personal inju ry in a crash.
(D Note
- Remove the guidance fixtures before
fold ing the rear seatback to prevent
damaging the seat cushion.
- To attach the child restraint secure ly, the
seat must be moved to the farthest rear pos ition, the seat height set to the low­
est posit ion and the head restra int must
be adjusted to the verti cal position
¢page 60.
-If you leave the guidance fixtures instal­
l ed for several days, they could leave a
mark on the upho lstery o n the sea t cush ­
i on and backrest in the a rea that the
guidance fixtures were insta lled . The up­
ho lstery would also be permanently
stretched around the guidance fixtures.
This applies especially to leather seats.

On vehicles with power adjustable rear
seats* some criteria must be observed
when attaching the child restraint using the
LATCH system:
- To attach the child restraint securely, the
seat must be moved to the farthest rear
position, the seat height set to the low­
est position and the head restraint must be adjusted to the vertical position
¢ page 60.
-If a child safety seat is attached to one of
the rear seats, this seat must not be ad­
justed using the power controls under
any circumstances. The

seatbacks
The tether anchors for the two* /three rear
seating positions are located in recesses in the
rear window shelf ¢
fig. 186. Vehicles with
two rear seating positions* are equipped with two tether anchors .
A tether is a straight orV-shaped strap that
attaches the top part of a child restraint to
special anchorage points in the vehicle.
Child Safety 193
The purpose of the tether is to reduce the for­
ward movement of the child restraint in a
crash, in order to help reduce the risk of head
injury that could be caused by striking the ve­
hicle interior .
Forward facing child restra ints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply with new child
head movement performance requirements.
These new performance requirements make a
tether necessary on most new child safety
seats .
.&_ WARNING
Improper installation of child restraints
will increase the risk of injury and death in
a crash.
- Always follow the instructions 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 collision . The anchors are de­
signed to withstand only those loads im­
posed by correctly fitted child restraints .
- Never mount two child restraint systems
on one LATCH lower anchor point.
- Never attach two child restraint systems to one tether strap or tether anchorage.
- 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 -

protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof*: the
windows and the sunroof* close leaving a
small open gap.
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the dep loy­
ment time is adapted in dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli ­
sion with the vehicle immediately ahead is al­
so calculated . If the system senses an immi­
nent collision the following functions can be
tr iggered :
- Braking guard
c::> page 99
- Tightening the safety be lts
- Closing the windows and the sunroof* (leav -
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli­
hood of a rear-end collision with the vehicle
coming from behind is also calcu lated.
If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
- Adjusting the seats: the settings for the
power head restrains, the upper sections of
the backrests and the pneumatic side bol­
sters* are optim ized for the front seats and
the outboard rear seats*. If a collision does
not occur, the previous seat settings are re­
stored.
Audi pre sense plus
Audi pre sense plus includes the funct ions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected .
A WARNING
-Audi pre sense cannot overcome the laws
of physics.
It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the risk o f a collision and serious personal
injuries.
- The sensors cannot always detect all ob­
jects . This increases the risk of a colli ­
sion.
- Audi pre sense does not detect people or
animals or objects that are crossing the
vehicle's path
c::> page 93.
-The radar sensor's vision can be reduced
by heavy rain, ice, snow, heavy road spray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from be ing ac­
curately detected and in some cases they
may not be detected at all.

temperature. This determines the current
state of charge and the power of the battery .
Idling current management
Idling current management reduces energy
consumption while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo ­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic en­
e rgy management distributes the energy gen ­
erated according to the needs of the individu­
al components. It regu lates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery.
Q) Tips
- But even energy management cannot negate the limits of physics. Consider
that the power and life of a battery are
li mited.
- If starting ability is threatened, the indi­
cator light[•) appears
Q page 16, D
Battery.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant electrical energy is re­
qu ired, but only a little is generated.
It is also
cr itica l if the engine is not running and electri­
cal components are turned on. In this in­
stance energy is being consumed but none is
being generated .
It is in precise ly these situations that you will
notice energy management active ly regu lat­
ing the d istribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of seve ral days or weeks, e lectr ica l compo­
nents are gradually cut back or switched off .
This reduces energy consumption and main­
tains starting capability over a longer period .
Some of the convenience functions may not
operate, such as the interior lights or the
power seat adjustment . The convenience
funct ions will be available again when you
switch on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use other MMI func­
tions, the battery is being discharged .
If starting capab il it y is jeopardized due to en­
ergy consumption, the following warning ap­
pears in the MMI display:
Please start the engine soon or the system

Although electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens mostly when
little energy is being generated and a grea t
deal consumed and the battery's state of
charge is not optimal.
T o b ring the energy bala nce back into equili­
brium, consumers which req uire espec ially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular 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 .,.
