crash
c:>fig. 161.
The airbag on the passenger side makes the front
seat a potentially dangerous p lace for a child to
ride. The front seat is not the safest place for a
child in a forward -facing child seat. It is a very
dangerous place for an infant or a larger child in
a rearward-facing seat.
_&. WARNING
Not using a chi ld safety seat, using the wrong
child safety seat or improperly install ing a
child restra int increases the r isk of serious
personal injury and death in a crash.
- Never install rearward-fac ing ch ild safety
seats or infant carriers on the front passen­
ger seat - even w ith an Advanced A irbag Sys­
tem. A child w ill be seriously injured and can
be k il led when the inflat ing airbag hits the
child safety seat or infant carrier with great
force and smashes the child safety seat and
child against the backrest, center armrest,
door or roof
c:> page 139, Child restraints on
the front seat -some important things to
know.
-Always install rearward-fac ing ch ild safety
seats or infant carriers on t he rear seat.
- Never install a rearward-facing child re­
straint in the forward-facing direction. Such
restra ints are des igned for the special needs
of infants and very small ch ildren and can­
not protect them properly if the seat is for­
ward-facing.
- If you must install a rearward fac ing ch ild
safety seat on the front passenger seat be­
c a use of exceptiona l circumsta nces and the

_&. 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 situat ion. To help red uce the risk of se­
rious personal injury and/or death:
- T he shoulder be lt must lie as close to the
center of the child's collar bone as possible
and must lie f lat 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 130.
-The rear side of the child safety seat should
be pos itioned as close as poss ible to the
backrest on the vehicle seat. Adjust or re­
move the rear seat head restraint if it is d if­
ficult to install the child seat with the head restra int in place
¢page 62. 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.

Child safety
_& 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 restraint you intend to install in your Audi.
- Improper use of child restra int anchors (in­
clud ing tether anchors) can lead to injury in
a collision. The anchors are designed to
withstand only those loads imposed by cor­ rectly fitted child restraints.
- Never mount two chi ld restraint systems on
one LATCH lower anchor po int.
- 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 ch ild restraint tether anchorages
to secure safety belts or other kinds of occu­
pant restra ints.
- Never secure or attach any luggage or other
items to the LATCH lower anchorages or to
the tether ancho rs.
- If a tether or other strap is used to attach a
child res traint to the front passenger seat,
make sure that it is not so tight, that it
ca uses the we ight-sens ing mat to measure
more weight than is ac tually on the seat.
- T he heav ier we igh t registered can make the
Advanced Airbag System work as though an adult were on the seat and dep loy the Ad ­
vanced Airbag when it must be suppressed
ca using serious or even fatal injury to the
child.

Intelligent Technology
Braking
What affects braking efficiency?
New brake pads
During the firs t 25 0 miles (400 km), new b rake
pads do not possess their full braking effect , they
have to be "broken i n" first ¢& . You can com­
pensate for this slight ly reduced braking power
by push ing harder on the brake pedal. Avoid
heavy braking loads during the break-in period .
Operating conditions and driving habits
The brakes on today's automobiles a re still sub ­
ject to wear, depend ing largely on ope rating con ­
ditions and driving habits¢& . On vehicles that
are either dr iven most ly in stop-and-go city traf­
f ic or are driven hard, the brake pads should be
checked by you r authorized Aud i dea ler more of­
ten than spec ified in the
Warranty & Mainte­
nance booklet .
Failu re to have your brake pads
i n spected c an resu lt in reduced bra ke pe rform­
ance.
O n steep slopes, you sho uld use the braking ef ­
fect of the eng ine . This way, you prevent unnec­
es sary wear on t he b rake system. If yo u m ust use
your b rake s, d o not hold the brakes down cont in­
uously. Pum p th e b rakes at intervals.
Operating noise
Noises may occur when brak ing depend ing on the
speed, b raking force and outs ide cond it ions such
as tempe ra tu re and humidi ty.
Effect of water and road salt
In certain s ituations, for example after driving
through water, in heavy ra in, afte r ove rnig ht con ­
densat ion or after washing your car, the b raking
effect can be reduced by mo isture or ice on the
b rake rotors and b rake pads . T he brakes must be
d ried first w ith a few careful b rake a pplica tions.
At highe r speeds and with t he windsh ield wipers
tur ned on, the br ake pads press aga inst the brake
rotors for a sho rt amoun t of time. This occur s at
regular intervals w it h out t he dr iver noticing and
p rov ides for better bra ke response time under
wet conditions.
180
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and t he b rakes are not used . Likewise, yo u clean
off accum ulated salt coating from brake discs
and pads with a few caut ious app lications of the
brake ¢& .
Corrosi on
There may be a tendency fo r dirt to build up on
the b rake pads and corrosion to form on the discs
i f the car is not driven regu larly or only for short
trips with little use of the brakes .
If the bra kes are not used frequent ly, or if corro­
s ion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed ¢ &.
Faults in th e brake system
If you shou ld notice a sudden increase in brake
pedal travel , then one of t he two brake circu its
may have failed¢& .
Low brake fluid level
Malfu nctions can occu r in the brake system if the
br ake fluid level is too low . The brake fluid leve l
is mo nitored electronica lly .
Brake booster
The bra ke booster i ncreases the press ure t hat
yo u ge nera te with the brake ped al.
It works only
whe n the eng ine is ru nning .¢ &
Brake lining wear status
Brake lining wea r may be c hecked by visua l in­
spection o f the condition of the brake pads
t hr ough t he openings in t he wheel. If necessary,
t h e wheel m ay be removed fo r thi s inspe ction

_& WARNING
- New brake pads don't have the be st sto p­
ping power and m ust be " broken-in" du ring
the initial 250 miles (400 kilometers). You
can compensate for this by p ressing the
brake pedal more firmly. This also app lies
later w hen new pads are installed.

..... N
0 ::..:: co ..... ..... -You should perform braking maneuvers for
the p urpose of clean ing the brake system
only if road conditions permit. Other road
users must not be put at risk - you may
cause an accident!
- Before descend ing a steep grade, reduce
speed and shift transm iss io n into a lower
gear or lowe r d riv ing range. Do not ride the
bra kes or hold the pedal down too long or
t oo often. This could ca use the bra kes to get
hot an d diminish brak ing efficiency.
- Do not "r ide t he b rakes" by resting your foot
on the pe dal when yo u do not inten d to
br ak e. This may cause the br akes to over­
heat, p remat ure wea r and increased stop ­
ping distance.
- Under certa in climatic and operating condi­
tions such as passing thro ugh water, driving
in heavy ra in or after washing the vehicle,
the effectiveness of the brakes can be re ­
duced. In w inte r, ice can acc umulate on the
brake pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry and ice coatings w ill be cleaned off after a
few careful b rake applica tions.
- Driv ing for an ex tended period of time on
salt-covered roads witho ut using your
bra kes can also affe ct bra king efficie ncy .
C le an off a ccumula ted s alt co ating from
bra ke discs and pads with a few caref ul
bra ke app lications.
- If you dam age the fro nt sp oiler, or if yo u in­
st all a diff erent spoi le r, be sure the ai r flow
to the front brakes is not obstr ucte d. Othe r­
wise the bra ke system could overheat reduc ­
ing the e ffectiveness of the entire b rake sys­
tem.
- Failure of one brake circuit will impair the
brak ing capability resulting in an increased
stopp ing distance. Avoid driving the vehicle
and have it towed to the nearest authorized
Audi dealer or qualif ied workshop.
- Never let the veh icle roll to a stop w ith the
engi ne shut off .
-If the brake booster is not working, the
bra ke pedal m ust be pressed conside rably
harder to make up for the lac k of booster
assista nee .
