Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack­
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on.
The control unit mo nitors the Advanced Air­
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you m ust take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air­
bag System abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .

A WARNING
If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's safe ­
ty and well-being require that the follow­ ing special precautions be taken :
- Make sure the forward -facing seat has
been designed and certified by its manu­
facturer for use on a front seat with a
passenger front and side airbag.
-Always follow the manufacturer's in­
structions provided with the child safety
seat or infant carrier.
- Always move the front passenger seat in­
to the rearmost position of the passen­
ger seat's fore and aft adjustment range,
and as far away from the airbag as possi­
ble 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 adjustment range.
- Always make sure the backrest is in 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 .
- If the light does not stay on, perform the
checks ¢
page 148, Monitoring the Ad ·
vanced 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 .
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 are
less than 4
ft. 9 in. (57 inches/1.45 meters) tall.
Fig. 164 Rea r seat : child p rop erly r estrained in a boo s­
te r se at
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 the
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 .
.. Secure unused safety belts on the rear seat
c::>page 163.
Children up to about 40 lbs. (18 kg) are best
protected in child safety seats designed for
their age and weight. Experts say that the
skeletal structure, particularly the pelvis, of
these children is not fully developed, and they must not use the vehicle safety belts without
a suitable child res traint.

Installing a child safety
seat
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 con­
vertible locking retractor to properly secure
child safety seats.
The safe ty belts eme rgency lock ing re tractors
fo r the re ar seats safe ty belts and for the
fro nt passenger's seat safety belt have a con­
vertible locking retracto r fo r child restraints.
The safety belt must be locked so that belt
webbing cannot unree l. The retractor can be
activated to lock the safety be lt 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
i s locked so that the child and child safety
seat will stay in place.
A lways remember: Even thoug h your veh icle is
eq uipped w it h an Advanced A irbag system, all
ch ildren , espec ia lly those 12 yea rs and yo ung­
e r, should always ride in the ba ck seat proper­
l y res traine d for thei r age and weig ht.

_& WARNING
--
Always take specia l precautions if you
must install a forwa rd 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
~ page 148, 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
<;hild.
- 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.
_&. 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
Child Safety 169
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 .
_&. 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
though an adult were on the seat and de­
ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child.
- 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 rearward-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer. •

LATCH Lower
anchorages and tether
for children
Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicable way
to attach the ch ild restraint on the vehicle
seat, Federa l regu lations require specia l lower
anchorages in vehicles and dev ices on new
child restraints to attach to the vehicle ancho­
rages .
The combination of the tether anchorages and
the lower anchorages is now generally called
the
LAT CH system for " Lower Anchorages and
Tethers for Children ."
F orward-facing child restraints 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 seats.
Installing a chi ld restraint that requires a top
tether without one can serious ly impair the
performance of the chi ld restraint and its abi l­
ity to protect the ch ild in a collision. Installing
a child restraint that requires a top tether
without the top tether may be a v iolation of
state law .
Ch ild restra int manufacturers offer LATCH
lower anchorages on the ir ch ild seats with
hook -on or push-on connectors attached to
adjustable straps .
In addition to the LATCH lower anchorages,
these child restraint systems usually require
the use of tether straps to help keep the child restra int firmly in place .
Tether ancho rage s
Your Audi Cabriolet is not equipped with a
LATCH system. It is no t equ ipped with top
tether anchorages. It is equipped with lower
anchorages only.
Your Cabriolet is equipped with the Active Rollover Protection System, which is integrat- ed into the backrest o
f the rear seat . The Ac ­
tive Ro llover Protection System dep loys up­
wards to he lp provide addit ional protection in
certain co llisions and crash s ituations. For this
reason, your vehicle is
not equipped with top
tether anchorages for use with forward -facing
child restra ints .
In Canada , provinc ial law requ ires that for­
ward-fac ing ch ild restra ints use both top teth­
er anchorages and lower anchorages; there ­
fore, it is
not possible to install a forward-fac­
ing ch ild restra int in this vehicle.
In the United States , child restraint installa­
t ion must conform w ith the child restraint
manufacture r's instructions . Check the in­
structions that come w ith the child restra int
o r contact the manufactu rer to determine if
the ch ild restraint may be insta lled fac ing fo r­
ward witho ut securing the top tether s trap .
A WARNING
=
Improper installation of child restraints
will increase the r isk of injury and death in
a crash.
- Always follow the instr uctions provided
by the manufacturer of the child re­
straint you intend to install in your vehi­
cle.
- Improper use of child restraint LATCH
lower anchorage points can lead to injury
in a collision. The LATC H 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 LATC H lower anchorage point .
- Never secure or attach any luggage or other item to the LATCH lower anchorag­
es .
(D Tips
In other countries, the term "ISOFIX" is
used to describe the lower anchorages .

You can compensate for th is sligh tly re duced
brak ing power by push ing harder on the brake
pedal. Avoid heavy braking loads d uring the
break-in per iod.
Operating condit ion s and d riv ing hab it s
The brakes on today's automobi les are st ill
subject to wear, depend ing largely on operat ­
ing conditions and driving habits¢.&. . On
vehicles that are either driven mostly in stop­ and-go city traffic or are driven hard, the brake pads should be checked by your author­
i zed Audi dealer more often than specified i n
the
Warranty & Maint enan ce booklet . Failure
to have your brake pads inspected can result
in reduced b rake performance.
On steep slopes, you should use the brak ing
effect of the engine . Th is way, you prevent un­
necessary wea r on the brake system. If you
must use you r brakes, do not hold the brakes
down continuously. P ump the b rakes a t inter ­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, braki ng force and outside condi­
tions such a s tempe ratu re a nd h umidity .
Due to the nature of the materials used i n ce ­
ramic brake rotors*, nois es may become more
apparent at low speeds.
Effect of w ater and ro ad s alt
In certain situat ions, for example after driving
through water, i n heavy ra in, after over night
condensation or after washing your car, the
b rak ing effect can be reduced by moistu re or
i ce on the bra ke roto rs and b rake pads . The
b ra kes must be dried fi rs t w it h a few caref ul
b ra ke app lications.
At h igher speeds and with the w indshield w ip­
e rs turned on, the brake pads p ress against
the brake rotors for a short amount of time.
This occurs a t reg ular in tervals wi tho ut the
d river noticing and provides for better brake
response time un der wet conditions.
The effectiveness of the brakes can be reduced
when the vehi cle is dr iven o n a salt -cove re d
Int ellig ent technolog y 179
road and the b ra kes are no t used. Likewise ,
you clean off acc umulated salt coating from
brake d iscs and pads with a few cautio us ap ­
plications of the brake
9 ,&. .
Due to the ir sur face character istics, ceramic
brake rotors* absorb moisture i n such condi­
tions. T his can cause a tempo rary reduction in
braking force compared to dry brakes. Yo u can
compensate for this by pressing the brake
pedal harder .
Corrosio n
There may be a tendency for dirt to b uild up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regularly or
o nly for short trips w ith litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros ion has formed on the discs, i t is adv isable
to clean off the pads a nd d iscs by braking
firmly a few times from a moderately high
speed

A WARNING ,~
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for you r vehi­
cle to drive through safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv­ ing.
When warming up, the vehicle is driven at a maximum engine speed of 6000 RPM in order
to raise the engine oil temperature to a mini­ mum of 140 °F (60 °C) . The tires also only
reach their full road holding capability once
they have warmed up .
The cooling fan can continue to run in your ve­ h icle after the engine is switched off. Howev­
er, driving the vehicle to cool it down is part ic­
ularly important . Du ring sporty driving, the
engine and brakes, the exha ust system, and
the transm ission all become ext remely hot.
Before you park the vehicle, you shou ld drive
Dri vin g and en vironm ent 185
it for a few miles/kilometers at light load in
the low rpm range to allow it to cool down.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in on environmentally sound manner.
"" Always use lead-free gasoline c> page 202,
Fuel supply.
"" Never run the tank down all the way to emp­
ty.
"" Never put too much motor o il in your engine
<=> page 212, ~ Adding engine oil .
""Never try to push- or tow-sta rt you r vehicle.
The catalyt ic converter is an efficient "clean­
up" device bui lt into the exhaust system of
the ve hicl e. The cata lytic conve rter bu rns
many of t he pollutants in the exha ust gas be­
fo re t hey are re leased into the atmosphere.
The exclusive use of unleaded fue l is critically
important for the life of the catalyt ic convert­
er and proper funct ion ing of the engine.
A WARNING ~
- The temperature of the exhaust system
is high, both when driving and after stop ­
ping the engine.
- Never touch the exhaust tail pipes once they have become hot . This could result
in burns .
- Do not park or operate the vehicle in areas where the hot exha ust system may
come in contact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire.
- Do not apply additional undercoating or rustproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substanc e used fo r undercoating could
overheat and cause a fire. •
•

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
""Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
"" Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l than is
burned starting the engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which cou ld result in over-
Driving and environment 187
'
heating or othe r damage to the vehicle or
