~ Secure unused safety belts on the rear seat
¢page 181.
Children up to at least 8 years old (over 40 lbs
or 18 kg) are best protected in child safety
seats designed for their age and weight. Ex­
perts say that the skeletal structure, particu­
larly the pelvis, of these children is not fully
developed, and they must not use the vehicle
safety belts without a suitable child restraint .
It is usually best to put these children in ap­
propriate booster seats. Be sure the booster
seat meets all applicable safety standards .
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass
across the child 's body in the right places. The
routing of the belt over the child's body is very
important for the child's protection, whether
or not a booster seat is used . Children age 12
and under must always ride in the rear seat.
Children who are at least 4
ft . 9 in. (57 in­
ches/1.45 meters) tall can generally use the
vehicle's three point lap and shoulder belts .
Never use the lap belt portion of the vehicle's
safety belt alone to restrain any child, regard­
less of how big the child is. Always remember
that children do not have the pronounced pel­
vic structure required for the proper function
of lap belt portion of the vehicle's three point
lap and shoulder belts. The child's safety ab­
solutely requires that a lap belt portion of the
safety belt be fastened snugly and as low as
possible around the pelvis. Never let the lap
belt portion of the safety belt pass over the
child's stomach or abdomen.
In a crash, airbags must inflate within a blink
of an eye and with considerable force. In order
to do its job, the airbag needs room to inflate
so that it will be there to protect the occupant
as the occupant moves forward into the air­
bag.
A vehicle occupant who is out of position and
too close to the airbag gets in the way of an inflating airbag. When an occupant is too
close, he or she will be struck violently and
Child Safety 185
will receive serious or possibly even fatal in­
jury.
In order for the airbag to offer protection, it is
important that all vehicle occupants, especial­
ly any children, who must be in the front seat
because of exceptional circumstances, be
properly restrained and as far away from the
airbag as possible . By keeping room between
the child's body and the front of the passen­
ger compartment, the airbag can inflate com ­
pletely and provide supplemental protection
in certain frontal collisions .
_&. WARNING
Not using a booster seat, using the boos­
ter seat improperly, incorrectly installing a booster seat or using the vehicle safety
belt improperly increases the risk of seri­
ous personal injury and death in a collision
or other emergency situation. To help re­
duce the risk of serious personal injury
and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possi­
ble and must lie flat and snug on the up­
per 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 that 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 inju­
ries in an accident or other emergency
situation
¢ page 140.
- The rear side of the child safety seat
should be positioned as close as possible
to the backrest on the vehicle seat. Ad­
just or remove the rear seat head re­ straint if it is difficult to install the child
seat with the head restraint in place
¢ page 57. Install the head restraint
again immediately once the child seat is
removed . Driving without head restraints
or with head restraints that are not prop­
erly adjusted increases the risk of serious
.
or fatal neck injury dramatically. ~

bly on the rear seat.
""Slowly pull the belt
all the way out.
""Route it around or through the child re­
straint belt path¢,&. .
"" Push the child safety se at down with you r
full weight to get the safety belt really tight.
"" Insert the belt tongue into the buckle for
that seating position.
""Guide the safety belt back into the retractor
until the belt lies flat and snug on the child
safety seat.
""You should hear a "clicking" noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to
pull the belt out of the retracto r. The con­
vertible locking retractor is now activated.
"" Make sure that the red release button is fac ­
ing away from the child restraint so that it
can be unbuckled quickly .
""Pull on the belt to make sure the safety belt
is properly tight and fastened so that the seat cannot move forward or sideways more
than one inch (2.5 cm).
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 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-
-
es. Ill-

@ Tips
-In Canada, the terms "top tether" with
"lower universal 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 chi ld restraint in
the seat without using the vehicle 's safety
belts. Anchorages provide a secure and easy­
to -use attachment and minimize the possib ili­
ty of improper child restraint installation .
All child restraints manufactured after Sep­
tember 1, 2002, must have lower anchorage
attachments for the
LATCH system .
Please remember that the lower anchorage
po ints are only intended for installat ion and
attachment of child restraints spec ifically cer­
tified for use with
LATCH lower anchorages .
Child restraints that are not equipped with the
lower anchorage attachments can still be in­
sta lled in compliance w ith th e child restra int
manufactu rer's instr uctions on using veh icle
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

Tether anchors and tether straps
Fig. 180 Tether ancho rs: attachment hook locations
behind the rear seatbacks
The tether anchors for the two/three* rear
seating positions are located o n the backside
of the rear seatbacks ¢
fig. 180. Vehicles with
two rear seating positions are equipped with
two tether anchors.
A tether is a straight or V-shaped strap that attaches the top part o f a child restraint to
specia l anchorage points in the veh icle.
The purpose of t he tether is to reduce the for­
ward movemen t of the ch ild restra int in a
crash, in order to help reduce the risk of head
injury that could be caused by striking the ve ­
hicle interior.
F orward facing child rest ra 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.
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 prov ided
by the manufacturer of the ch ild re­
st rain t you intend to install in your Audi.
- Improper use of ch ild restra int anchors
(including tether anchors) can lead to in­
jury in a co llision. The anchors are de­
signed to w ithstand on ly those loads im ­
posed by corre ctly fitted ch ild restraints. -
Never mount two child restraint systems
on one LATCH lower anchor point.
- Never attach two child restraint systems

Audi pre sense
Preventative passenger
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 deploy­
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 92
- 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)
Audi pre sense plus*
Audi pre sense plus includes the functions 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.
_& 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 r isk of a collis ion and serious personal
in juries .
- The sensors cannot always detect all ob­
jects. This increases the risk of a colli­
s10n.
-Aud i pre sense does not detect people or
an im als or objects that are crossing the
veh icle's path
c::> page 86.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road sp ray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from being ac ­
curately detected and in some cases they
may not be detected at all.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au­
thorized Audi dealer check to make sure
that the system is working properly.

196 Intelligent technology
Intelligent technology
Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather condit ions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
drive r inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road during ex treme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
