Toddlers and children who are older than one
year up to about 4 years old and weigh more than
20 lbs. (9 kg) up to 40 lbs. (18 kg) must always
be properly restrained in a child safety seat certi­
fied for their si ze and weight¢
fig. 143 and
¢fig. 144 .
The airbag on the passenger side makes the front
seat a potentially dangerous place for a child to ride . The front seat is not the safest place for a
child in a forward-facing child safety seat. It is a
very dangerous place for an infant or a larger
child in a rearward-facing seat.
.8, 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 collision or oth­
er emergency situation.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates.
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 and child against the backrest, center armrest, door
or roof.
- Always install rearward-facing child safety
seats on the rear seat.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rearward-facing child safety seat in a
rear seating position and have the airbag
system inspected by your authorized Audi
dealer.
- The rear side of the child safety seat should be positioned as close as possible to the
backrest on the vehicle seat . Adjust or re­
move the rear seat head restraint if it is dif-
Child safety
ficult to install the child seat with the head
restraint in place

head restraint again immediately once the
child seat is removed . Driving without head
restraints or with head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.

.8, WARNING
= -
If exceptional circumstances require the use
of a forward-facing child restraint on the front
passenger's seat, the child's safety and well­
being require that the following special pre­
cautions be taken:
- 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 .
-Always follow the manufacturer's instruc­ tions provided with the child safety seat or
infant carrier.
- 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 ad­
justment range.
- Always make sure the backrest is in an up­
right position.
- 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 light does not stay on, perform the
checks ¢

vanced Airbag System.
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and 80
lbs. (18 kg and 36 kg) who ore less than 4 ft .
9
in. (57 inches/1.45 meters) tall.
Fig . 14 5 Rear seat: ch ild p roperly restra ined in a booster
seat
The vehicle's safety belts alone will not fit most
children until they are at least 4
ft. 9 in . (57 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg) . Booster seats raise these c hildren up so
that the safety belt will pass properly over the
stronge r pa rts of their bod ies 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 chi ld on a booster seat .
• The shoulder be lt must lie as clo se to the cen­
t er of the child's collar bone as poss ible and
must lie flat and sn ug on the upper body . It
must never lie across the throat or neck . The
lap belt must lie across the pelvis and never
across the stomach or abdomen . Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if necessary.
• Secu re unused safety belts on the rear seat
~ page 155.
Children up to about 40 lbs. (18 kg) are best pro­
tected in child safety seats designed for their age
and weight . Experts say that the skeletal struc­
ture, part icularly the pelvis, of these ch ildren is
not f ully deve loped, and they must not use the
158
vehicle safety be lts without a suitable child re­
straint.
It i s usually best to put t hese chi ldren in appro­
pr iate booste r seats . Be sure the boos ter seat
meets a ll applicab le safety standards.
Booster seats ra ise the sea ting pos ition of t he
ch ild an d repos ition bo th the lap and shoulder
parts o f the safety bel t so th at they pass across
the chi ld's body in the right places . The rout ing of
the be lt over the chi ld's body is very important
for t he chi ld's protection, whether or not a boos­
ter seat is used. C hildren age 12 and under must
always ride in the rear seat.
Children who are at least 4
ft . 9 in . (57 inc hes/
1.45 meters) tall ca n generally use the vehicle's
three po int lap and shoulder be lts. Never use the
lap belt portion of the vehicle's safety belt alone
to rest rain any child, regardless of how b ig the
c hi ld is . A lways remember that ch ild ren do not
have the p ronounced pe lvic st ructure required for
the p roper func tion of lap belt port ion of the ve­
h icle 's th ree po int lap and shoulder be lts. The
ch ild' s sa fety abso lutely requires tha t a lap belt
portion of the safety belt be fastened snug ly and
as low as possible around the pelvis . Never let
the lap be lt portion of the safety belt pass over
the child's stomach or abdomen.
In a crash, a irbags must inflate within a blink of
an eye and with considerable force . In order to do
i ts job, the airbag needs room to inflate so that it
will be there to protect the occ upant as the occu­
pant moves forward into the airbag .
A ve hicle occupant who is out of pos ition and too
close to the a irbag gets in the way of an inflating
airbag. When an occupant is too close, he or she
will be struck vio lent ly 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 ch ildren, who must be in the front seat be­
cause of exceptional circumstances, be prope rly
restrained and as far away from the airbag as
poss ible. By keep ing room betw een the ch ild 's ..,

body and the front of the passenger compart­
ment, the airbag can inflate completely and pro­
vide supplemental protection in certain frontal
collisions .
& WARNING
Not using a booster seat, using the booster
seat improperly, incorrectly installing a boos­
ter seat or using the vehicle safety belt im­ properly increases the risk of serious personal
injury and death in a collision or other emer­
gency situation. To help reduce the risk of se­
rious personal injury and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possible
and must lie flat and snug on the upper
body.
It must never lie across the throat or
neck. The lap belt must lie across the pelvis
and never across the stomach or abdomen.
Make sure the belt lies flat and snug. Pull on
the belt to tighten if necessary.
- Failure to properly route safety belts over a
child's body will cause severe injuries in an
accident or other emergency situation
~ page 120.
-The rear side of the child safety seat should
be positioned as close as possible to the
backrest on the vehicle seat . Adjust or re­
move the rear seat head restraint if it is dif­
ficult to install the child seat with the head
restraint in place
~page 56. Install the
head restraint again immediately once the
child seat is removed. Driving without head
restraints or with head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates.
- Never let a child stand or kneel on any seat.
- Never let a child ride in the cargo area of
your vehicle.
- Always remember that a child leaning for­
ward, sitting sideways or out of position in any way during an accident can be struck by
a deploying airbag. This will result in serious
personal injury or death .

Securing child seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas­
senger's seat can be locked with the convertible
locking retractor to properly secure child safety
seats.
The safety belts emergency locking retractors for
the rear seats safety belts and for the front pas­
senger 's seat safety belt have a convertible lock­
ing retractor for child restraints. The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving. A child
safety seat can only be properly installed when
the safety belt is locked so that the child and child safety seat will stay in place .
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 re-
strained for their age and weight . ..,_

Child safety
A WARNING
Improperly installed child safety seats in­
crease the risk of serious personal injury and
death in a collision .
- Always make sure that the safety belt re­
tractor is locked when installing a child safe ­
ty seat . An unlocked safety belt retractor
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 collision.
- If the backrest is not securely latched, the
child and the child restraint will be thrown
forward together with the backrest and will
strike parts of the vehicle interior. The child
can be seriously injured or killed.
- Never install rearward-facing child safety seats or infant carriers on the front passen­
ger seat . A child will be seriously injured and
can be killed when the passenger airbag in­
flates.
- 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 install rearward-facing child safety
seats or infant carriers on the rear seat.
- Forward-facing child safe ty seats or infant
carriers installed on the front passenger's
seat may interfere with the deployment 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.

A WARNING
-
Always take special precautions if you must
install a forward or rearward-facing child re ­
straint on the front passenger's seat in excep­
tional situations:
- Whenever a forward or rearward -facing
child restraint is installed on the front pas­
senger 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 ~
page 138, Monitoring
the Advanced Airbag System.
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER 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 protection.
- An improperly installed child restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child .
- Always carefully follow the manufacturer 's
instructions provided with the child safety
seat or carrier.
- Never place additional items on the seat
that can increase the total weight registered
by the weight-sensing mat and can cause in­
jury in a crash .
A WARNING
Forward-facing child restraints:
- Always make sure the forward-facing seat
has been designed and certified by its man ­
ufacturer for use on a front seat with a pas­
senger front and side airbag .
- Never put the forward-facing child restraint up , against or very near the instrument pan­
el.
-Always move the passenger seat into its
rearmost position in the seat's fore and aft
-

Child safety
-Always make sure the seat backrest to which
the child restraint is installed is in an up­
right position and securely latched into
place and cannot fold forward. Otherwise,
the seatback with the child safety seat at­
tached to it could fly forward in the event of
an accident or other emergency situation.

vertible locking retractor for child restraints.
If the convertible locking retractor should be ac­
tivated inadvertently, the safety belt must be un­
fastened 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.
_& WARNING
Improperly installed child safety seats in­
crease the risk of serious personal injury and
death in a collision.

LATCH system (Lower
anchorages and tethers
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, Fed­
e ral regulations requi re specia l lower anchorages
i n veh icles and devices on new child restrain ts to
attach to the vehicle anchorages.
The combination of the tether anchorages and
the lower anchorages is now generally called the
L A TCH system for " Lower Anchorages and
Tethers for Children ."
F orward-facing child restrain ts manufactured af­
ter September 1, 1999, are requi red by U.S. fed­
eral regu lations to comply with new child head
movement per formance requirements . These
new performance requirements make a tether
necessary on most new chi ld seats.
I nstall ing a chi ld restraint that requ ires a top
tether witho ut one can serio usly impair the per ­
formance of the chi ld restraint and its ability to
protect the child in a coll is ion. Insta lling a child
restra int that requires a top tether without the
top tether may be a violation of state law.
Child restraint manufact urers offer LATCH lower
anchorages on their child seats with hook-on or
push-on connectors attached to adjustable
s t raps .
In add ition to the LATCH lower anchorages , these
child restraint systems usua lly require the use of
tether straps to help keep the child restraint
f irmly in place .
A WARNING
Improper installation of chi ld restraints will
increase the risk of in ju ry and death in a crash.
- Always follow the instructions prov ided by
the manufacturer of the child restra int you
intend to install i n your veh icle.
- Never install a child restraint without a properly attached top tether strap if the
Chil d sa fe ty
child restraint manufacturer's instructions
require the top tether strap to be used.
- Improper use of child rest raint LATCH lower
anchorage points can lead to injury in a co lli­
sion . The LATCH lower anchorage points are
des igned to w ithstand only those loads im­
posed by correctly fitted child restraints .
- Never mount two child restra int systems on
one LATCH lower anchorage po int .
- Never secure or attac h any luggage or other
item to the LATCH lower anchorages.
(D Tips
In Canada, the terms "top tether" with "lower
universa l anchorages" (or " lower universal an ­
chorage bars") are used to describe the sys­
tem.
- In other countries, the term "ISOFIX" is used to describe the lower anchorages.

Child safety
-Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether anchorages
to secure safety belts or other kinds of occu­
pant restraints.
- Never secure or attach any luggage or other
items to the LATCH lower anchorages or to
the tether anchors.
- If a tether or other strap is used to attach a
child restraint 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 .
- The heavier weight registered can make the
Advanced Airbag System work as though an
adult were on the seat and deploy the Ad­
vanced 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 be­ cause 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 authorized Audi dealer.

(D Note
If you leave the child restraint with the tether
strap firmly installed for several days, this
could leave a mark on the upholstery on the
seat cushion and backrest in the area where
the tether strap was installed. The upholstery
would also be permanently 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 sys­
tems come with a tether. Please read and heed
the child restraint system manufacturer's instruc­
tions carefully to determine how to properly in­
stall 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 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, or
door.

Qpage 16.
What you should know
The highest priority is given to maintaining start­
ing capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time of
year . Ab undant electrical energy is required, but
only a little is generated. It is also critical if the
engine is not runn ing and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situat ions that you wi ll no­
tice energy management actively regulating the
d istr ibut io n of energy.
Vehicle s tand s for an exte nded p eriod
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca­
pability over a longer period. Some of the con­
ven ience funct ions may not operate, such as the
interior lights or the powe r seat adjustment. The
conven ience functions will be ava ilable again
when you sw itch on the ign it io n and start the en­
g ine.
With th e engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI funct ions,
the battery is being discha rged .
If starting capability is jeopardized due to energy
consumption, a message appears in the MMI dis­ p lay . The message ind icates that the system will
be sw itched off automat ica lly in a moment. If
you wish to cont inue using the functions , you
have to start the engine .
176 With the en
gine running
Although elec trical energy is generated when the
vehicle is being d riven, the battery can become
discharged . This happens mostly when litt le en­
ergy is being generated and a great deal con­
sumed and the battery's state of charge is not
optimal.
T o bring the energy ba lance back into equilibri­
u m, consumers whic h req uire especially large
amounts of energy are temporari ly cut back or
switched off. Heating systems in part icular re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* o r the heated rear
window are not heating, they have been tempo­
r ari ly cut back o r switched off . Th ese systems w ill
be ava ilable again as soon as the ene rgy ba lance
has been res tored.
You w ill also notice that engine id le speed has
been increased slightly . Thi s is normal and not a
ca use for concer n. By increasing eng ine idle
speed the addi tional energy required is gene rated
and the battery is charged.
