172 Child Safety
-Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat in 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 air­
bag system inspected immediately by
your Audi dealer.
_&, WARNING
- Forward-facing child seats installed on
the front passenger seat may interfere
with the deployment of the airbag and
cause serious personal injury to the
child.
- 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 the follow­ ing special precautions to be taken:
- Always make sure that the forward-fac­
ing seat has been designed and certi­
fied by its manufacturer for use on a
front passenger seat with a front and
side airbag.
- Always carefully follow the manufac­
turer's instructions provided with the
child seat or infant carrier.
- Never install a child restraint without a
properly attached top tether strap if
the child restraint manufacturer's in­
structions require the top tether strap
to be used.
- Never put the forward-facing child re­
straint up against or very near the in­
strument panel.
- Always set the safety belt upper an­
chorage to the adjustment position
that permits proper installation in ac­
cordance with the child restraint manu­
facturer's instructions.
-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 in­
stalling the child restraint. The back­
rest must be adjusted to an upright po­
sition .
- Always make sure that nothing pre­
vents the front passenger's seat from
being moved to the rearmost position
in its fore and aft adjustment range.
- Never place objects on the seat (such
as a laptop, CD player, electronic
games device or power inverter). These
may influence the electrical capaci­
tance measured by the capacitive pas­
senger detection system and can also
fly around in an accident and cause se­
rious personal injury.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device or power inverter) on the
front passenger seat if the device is
connected to the 12-volt socket or the
cigarette lighter socket.
- If a seat heater has been retrofitted or
otherwise added to the front passen­
ger seat, never install any child re­
straint system on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or
other liquids on the front passenger
seat cushion .
- Always 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
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the forward-facing child
seat in a rear seating position and have
the airbag system inspected by your
authorized Audi dealer.
- Always buckle the child seat firmly in
place even if a child is not sitting in it.

176 Child Safety
-The child and the passenger can also
injure each other in an accident.
- Never install rear-facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen­ ger 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 rear-facing child safety
seats or infant carriers on the rear seat.
- Forward-facing child safety seats instal­
led on the front passenger's seat can in­
terfere with the airbag when it inflates
and cause serious injury to the child. Al­
ways install forward-facing child safety
seats on the rear seat.
- 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 precautions be taken:
- Make sure the forward-facing seat has
been designed and certified by its man­
ufacturer for use on a front seat with a
passenger front and side airbag.
- Always carefully follow the manufac­
turer's instructions provided with the
child safety seat or carrier.
- Always move the front passenger seat
into the rearmost position of the pas­
senger 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 pre­
vents the front passenger's seat from
being moved to the rearmost position
in its fore and aft adjustment range.
- Always make sure that the backrest is
in the upright position .

The vehicle's safety belts alone will not fit
most children until they are at least 4 ft . 9 in .
(57 inches/1.45 meters) tall and weigh about
80 lbs.
(36 kg). Booster seats raise these chil­
dren up so that the safety belt will pass prop­
erly over the stronger parts of their bodies
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 re­
strain a child on a booster seat.
"" The shoulder belt must lie as close to th e
center of the child's collar bone as possible
and mu st 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 .
"" If you must transport an older child in a

Activating the convertible locking
retractor
Use the convertible locking retractor to se­
cure a child restraint.
A lways heed the child safety seat manufactur ­
er's instructions when install ing a ch ild re­
straint in your vehicle. To activate the conver­
tib le locking retractor:
,. Place the child restraint on a seat, prefera­
bly on the rear seat .
,. Slow ly pull the be lt

,. Route it around or thro ugh the ch ild re­
stra int be lt path¢ &.
,. Push the child sa fety seat down wit h your
f ull weight to get the safety belt rea lly tight .
,. Inse rt the be lt tongue into the buckle for
that seating position.
,. Gu ide the safety belt back into the retractor
until the belt lies flat and snug on the child
safety seat .
,. You should hear a "click ing" noise as the
belt w inds bac k into the ine rtia reel. Test the
conve rtible locking retractor by pull ing on
the belt . Yo u should no longe r be able to
pull the belt out of the ret ractor . The con­
vertib le locking retractor is now activated .

LATCH 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, 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 lowe r anchorages is now generally called
the
LAT CH system for " Lower Anchorages and
T ethers for Children."
F orward-facing child restraints manufactured
after September 1, 1999, are requi red by U .S.
federal regulations to comply with new chi ld
head movement performance requirements.
Child Sa fet y 185
These new performance req uirements make a
tether necessary on most new child seats.
Installing a ch ild restra int that requires a top
tether without one can seriously impair the
performance of the child restraint and its abil ­
ity to protect the child in a collision . Insta lling
a chi ld restraint that requires a top tether
without the top tether may be a violat ion of
sta te law.
Child restraint manufacturers offer LA TCH
l ower anchorages on their child seats w ith
hook-on or push-on connectors attached to
adjustable st raps.
In addition to the LATCH lower anchorages,
these chi ld restraint systems usually require
the use of tether straps to he lp keep the child
restraint f irmly in place .
A WARNING
Improper installat ion of child restra ints
will increase the r isk 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 vehi­
cle.
- Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instruc­
tions require the top tether st rap to be
used .
- Improper use of child restraint LATC H
lower anchorage points can lead to injury
in a collision. The LATCH lowe r anchorage
points are designed to withstand on ly
those loads imposed by correctly fitted
child restraints.
- Never mo unt two child restraint systems
on one LATCH lower anchorage point.
- Never secure or attach any luggage or
other item to the LATCH lower anchorag­
es.

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EDR), ins talled by some manu­
facture rs fo r the express p urpose of capturing
data for retrieval after an accident or cras h
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restr ict 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 ltho ugh yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine f unction, 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 norma l vehicle op­
erat ion for diagnostic and repa ir 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 ove r a ve ry limited pe riod of
time and stored when a sys tem faul t or o ther
cond ition is sensed by a cont ro l u nit. Some of
the data then stored may re late to vehicle

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 ve hicle control. It works
only when the eng ine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
o ut of control and he lps you to get the veh icle
back under control by se lectively braking the
whee ls, and/or reducing eng ine power and
providing steer ing ass istance to he lp hold the
vehicle o n the dr iver's intended course. The in­
dicator light
G) in the inst rument cluster
blinks when ESC is ta king action to help yo u
control the veh icle.
ESC has limitations.
It is importa nt to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under a ll cond it ions you may come up aga inst.
F or example, ESC may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is sudden ly covered w ith water,
s lush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the ve hicle
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 in terrupted
and the vehicle cannot be braked or steered .
D uring 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 availab le tract ion, or keep a ve hicle
on the road if road departure is a result of
drive r inattent io n. Instead, ESC imp roves the
poss ibil ity of keeping the vehi cle under con ­
trol and on the road during ex treme maneu­
vers by using the d river's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
ca uses you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

efficiency .
- Do not "ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to brake . This may cause the brakes to
overheat, p remature wear and increased
stopping distance.
- Under certain cl imatic and operating
conditions such as passing thro ugh wa ­
ter, dr iv ing in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced . In winter, ice can
accumu late on the brake pads, lin ings,
discs and drums . Carefully app ly brakes
for a test. Brakes will dry and ice coat­
ings w il l be cleaned
off after a few care­
fu l brake applicat ions.
- Driving for an extended period o f time on
salt- covered roads wi thout using your
brakes can a lso affect braking efficiency .
Clean
off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
f low to the front brakes is not obstruct­
ed. Otherw ise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capab ility result ing in an in­
creased stopping distance . Avoid driving
the vehicle and have it towed to the near-
est A udi dealer or qualified wo rkshop.

-Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .

Q _& .
Winter tires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, eve n wit h
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea ­
son tires) for improved driveability and brak ­
ing : these tires must be mo unted on
all fou r
wheel s. See also ¢ page 255 , Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this no rma lly also app lies to ve hicles
