will increase your risk of being injured or killed.•
Improperly worn safety belts .
Incorrectly positioned safety belts can cause severe inju­
ries.
Wearing safety belts improperly can cause serious injury or
death. Safety belts can only work when they are correctly
positioned on the body. Improper seating positions reduce
the effectiveness of safety belts and w ill even increase the
risk of injury and death by moving the safety belt to critical
areas of the body. Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and strikes an occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all vehicle occu­
pants and especially for children . Therefore:
- Never permit anyone to assume an incorrect sitting posi­
tion in the vehicle while traveling=>,& .
& WARNING
Improperly worn safety belts increase the risk of serious personal
injury and death whenever a vehicle is being used.

Child Safety Ill
-------------------"'---
& WARNING (continued)
• 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 arm rest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure on
the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
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, immediately install the rearward-facing child safety seat
in a rear seating position and have the airbag system inspected by
your authorized Audi dealer. •
Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer 's instruc­
tions when installing a child restraint in your vehicle. To acti­
vate the convertible locking retractor:
- Place the child restraint on a seat, preferably on the rear
seat .
Controls and equip­
ment Safety first Vehicle operation
-
Slowly pull the belt all the way out.
-Route it around or through the child restraint belt path
=>& .
- Push the child safety seat down w ith your 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 retractor. The convertible locking
retractor is now activated.
- Make sure that the red release button is facing 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).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety 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 crash.

Child Safety --------------------"'---l'ff'II
Installing a child restraint that requires a top tether without one can
seriously impair the performance of the child restraint and its ability
to protect the child in a collision. Installing a child restraint that
requires a top tether without the top tether may be a violation of
state law.
Child restraint manufacturers offer LATCH lower anchorages on their
child seats with hook-on or push-on connectors attached to adjust­
able straps.
In addition to the LATCH lower anchorages, these child restraint
systems usually require the use of tether straps to help keep the child
restraint firm ly in place.
Tether anchorages
Your Audi Cabriolet is not equipped w ith a LATCH system. It is not
equipped with top tether anchorages. It is equipped with lower
anchorages only .
Your Cabriolet is equipped with the Active Rollover Protection
System, which is integrated into the backrest of the rear seat. The
Active Rollover Protection System deploys upwards to help provide
additional protection in certain collisions and crash situations. For
this reason, your vehicle is
not equipped with top tether anchorages
for use with forward-facing child restraints.
In Canada, provincial law requires that forward-facing child
restra ints use both top tether anchorages and lower anchorages;
therefore, it is
not possible to install a forward-facing child restraint
in this vehicle.
In the United States, child restraint installation must conform with
the child restraint manufacturer's instructions. Check the instruc­
tions that come with the child restraint or contact the manufacturer
to determine if the child restraint may be installed facing forward
without securing the top tether strap.
Controls and equip­
ment Safety first Vehicle operation
& 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 vehicle.
• Improper use of child restraint LATCH lower anchorage points
c an lead to injury in a collision . The LATCH lower anchorage points
are designed to withstand only those loads imposed by correctly
fitted child restraints.
• Never mount two child restraint systems on one LATCH lower
anchorage point.
• Never secure or attach any luggage or other item to the LATCH
lower anchorages.
(I) Tips
In other countr ies, the term "ISOFIX " is used to descr ibe the lower
anchorages. •

The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR w ill also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self-test. You can activate a deactivated ASR if required by
pressing the=>
page 240, fig. 213 button. When it is activated, the
message
ESP/ASR on appears briefly in the display .
Deactivating
You can deactivate the ASR if required by pressing the button (for less
than 3 seconds) =>
page 240, fig. 213. With the ASR deactivated , the
ESP check light comes on, see=>
page 14 . The message ASR off
appears in the display as well. The ASR can be deactivated at any
speed .
The ASR should normally be activated a ll the time. Only in certain
exceptional situations when some slip is desirable does it make sense
to deactivate the ASR. Examples:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck .
When the abnormal situation is over, you should activate the ASR again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[I] Tips
To ensu re that the ASR works properly, all four whee ls must be fitted
with ident ical t ires. Any differences in rolling radius of the t ires can
cause the system to reduce eng ine power when this is not desired.

Safety first
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending la rgely on ope rating 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 authorized
Audi dealer more often than specified in the
Warranty & Mainte­
nance booklet.
Failure to have your brake pads inspected can result
in reduced brake performance .
On steep slopes, you should use the braking effect of the engine. This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when brak ing depending on the speed, braking
force and outside cond itions such as temperatu re and humid ity.
Moisture or road salt
If you are driving faster than 31 mph (50 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regula r interva ls so as to improve reaction time when braking on wet
surfaces. You, the driver, will not not ice anything.
Under certain condit ions, for example, when driving through water or
very heavy rai n, or even after washing your vehicle, the braking effect
can be reduced due to moisture (or in free zing conditions ice) on the
bra ke pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings.
Th e effectiveness of the brakes can be reduced when the vehicle is
dr iven on a salt-covered road and the brakes are not used. H ere too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=>&,.
Vehicle care Technical data

Intelligent technology
'-------------------------------------------------
Corrosion
T he re may be a te ndency fo r d irt to build u p on the bra ke pads and
co rrosion to form on the d iscs if the car is not dr iven reg ularly o r only
for short trips with litt le use of the bra kes .
If the brakes a re not used freq uen tly, or if co rrosion has formed o n
the discs, it is advisable to clean off the pads and discs by braking
fir mly a few times from a mode rat ely h igh spee d~ & .
Faults in the brake system
If yo u sh ou ld noti ce a sudden increase in b rake peda l trave l, then one
of the two brake circu its may have failed~& .
Low brake fluid level
Ma lfunctions can occ ur in t he brake system if the brake fluid level is
t oo low. The bra ke f lu id level is moni tore d elec tron ically.
Brake lin ing wear status
Brake lin ing wear may be checked by v isua l inspect ion of the condi­
tion of the brake pads throu gh the open ings in the whee l.
If neces­
sary, the whe el may be removed fo r thi s insp ection~
page 320,
"Changing a w hee l".
& WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk - you may cau se an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake . This may cause the brakes to overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s not obstructed .
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.

& WARNING
• 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 mu st be pressed considerably harder to
make up for the lack of booster assistance. •
