Folding top
General
The comprehensively engineered design of the fabric folding top
allows it to be operated quickly and simply. When open, the folding
top is stowed completely in a tonneau provided specifically for this
purpose.
In normal operating conditions, the folding top is wind -and water ­
proof. Under certain circumstances, a small quantity of droplets might form, but only in extremely inclement weather, e.g. torrential
or continuous heavy rain. This is normal and not a cause for
concern .
Follow the care instructions =>
page 203, "Folding top care" to main ­
tain the folding top's attractive appearance and to keep it wind- and
waterproof. Please follow these instructions as well:
• Stow and open the folding top only when it is clean . When the
top is folded away, sharp -edged contaminants can build up as silt
and cause wear spots on the rear window, which may damage the
folding top over time. Of course, ice and snow should also be
removed before opening the folding top.
• Under no circumstances should you use sharp -edged or abrasive
objects to remove ice and snow. Use a commercial ice scraper to
remove ice from of the rear window.
• The folding top should be opened only if it is completely dry . If
the folding top is opened and then stored wet, unattractive indenta ­
tions may develop. In addition, over time, mold and mildew stains
can develop.
• Do not leave the folding top open for several weeks at a time;
instead, open and close it from time to time so that the fabric does
not discolor where it folds, and to prevent creases from forming. This is especially
important if it happens to be stowed while still
damp on occasion.
• Because the fabric becomes less flexible when temperatures
drops below zero, we recommend not operating the folding top
below0°C.
& WARNING
• When operating the folding top, make sure that any external
factors {e.g. the wind) do not impair its function or endanger other
drivers.
• Never drive while the folding top is not properly secured. Other­
wise, it may be pulled open by the wind. This can cause injuries
and damage to the vehicle -danger of an accident!
• When opening and closing the folding top make sure to keep
yourself and others clear of all moving parts. Risk of injury!
0 Note
• Always make sure that there is enough clearance above the
vehicle so that the folding top is not damaged when opening and
closing.
• Do not place any objects in the tonneau to avoid damage when
opening the folding top.
[ i] Tips
• The folding top should be operated only with the ignition
switched on.
• When parking the car with the folding top open, bear in mind
that the vehicle's interior is not protected from damage due to unex­ pected weather conditions, or unauthorized access. It is therefore
advisable to close the folding top before leaving the vehicle. If

In freezing or near freezing conditions:
• Always check that the wiper blades are not frozen to the glass
before you turn the wipers on. Loosen a wiper blade which is frozen
in place before operating the wipers to prevent damage to the wiper
blade or the wiper motor.
• Do not use the wipers to clear a frosted window. Using the
wipers as a convenient ice scraper wil l destroy the wiper blades.
• Before you take your vehicle to an automatic car wash, make sure
you have the windshield wiper system switched off (lever in position
0), otherwise the windshield wiper system could get damaged in the
car wash if it should sudden ly come on .
[ i] Tips
• The rain sensor is pa rt of the interva l wiping system. Turning off
the ignition will also deactivate the rain sensor . To reactivate the
sensor, switch off the interva l wiping function, then switch it back
on again.
• Worn or dirty windshield wiper b lades cause smearing, which
can affect the operation of the light/rain sensor *. Check the condi ­
tion of your windshield wiper b lades regular ly .

Using the previously recommended setting is the quickest way to
achieve a comfortable climate in the vehicle . T his setting should
therefore on ly be changed when persona l comfort levels or certain
circumstances require it .
The climate contr ols are a combination of automatic heating and
ventilation systems and a cooling system which dehumidifies and coo ls the a ir inside the veh ic le .
The climate controls automa tically ma intain a temperature once it
has been set . T he temperature of the air from the vents, fan speed
(air volume) and air dis tribution are also automa tica lly adjusted . The
system also takes into account strong sunshine so that manual
adjustment is no t necessary. So in al most a ll cases,
automatic mode
offers the best conditions for the comfort of the occupants at all
times of the year~
page 101.
Please note :
In cooling mode, relative humidity in the interior is reduced. This
prevents the w indows from fogging up.
When relative humidity and temperatures outside are high,
conden­
sate
can drip from the air conditioning evaporator and form a poo l
of water under the vehicle . This is normal and not an indication of a
leak!
When outside temperatures are low, the fan does not switch to a
higher speed until the coolant has reached an adequate tempera­
ture, with the exception of the defrost setting .
When accelerating at wide -open throttle, the air conditioning
compressor is temporarily switched off to maintain full engine
power .
I n order to ensure eng ine cooling under extreme engine loads, the
compressor is switched off if coolant temperatures climb too high. _,,,

-Airbag system ----=---'---------------------------------------------
& WARNING (continued)
• To reduce the risk of injury when the airbags inflate, the driver
and passengers must always sit in an upright position, must not
lean against or place any part of their body too close to the area
where the airbags are located .
• Occupants who are unbelted, out of position or too close to the
airbag can be seriously injured by an airbag as it unfolds with
great force in the blink of an eye~ page
147.
& WARNING
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.
• If you must install a rearward facing child safety seat on the
front passenger seat because of 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 airbag system inspected by your
Audi dealer .
& WARNING
Objects between you and the airbag will increase the risk of injury
in a crash by interfering with the way the airbag unfolds or by
being pushed into you as the airbag inflates .
• Never hold things in your hands or on your lap when the vehicle
is in use .
• Never transport items on or in the area of the front passenger
seat . Objects could move into the area of the front airbags during
& WARNING (continued)
braking or other sudden maneuver and become dangerous projec­
tiles that can cause serious personal injury if the airbags inflate.
• Never place or attach accessories or other objects (such as cup
holders, telephone brackets, large , heavy or bulky objects) on the
doors , over or near the area marked "AIRBAG" on the steering
wheel, instrument panel , seat backrests or between those areas
and yourself . These objects could cause injury in a crash, espe­
cially when the airbags inflate .
• Never recline the front passenger's seat to transport objects .
Items can also move into the area of the side airbag or the front
airbag during braking or in a sudden maneuver . Objects near the
airbags can become projectiles and cause injury, particularly when
the seat is reclined.
& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a history of asthma or other breathing
conditions.
• To reduce the risk of breathing problems , those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the vehicle or opening windows or doors .
• If you are in a collision in which airbags deploy, wash your
hands and face with mild soap and water before eating .
• Be careful not to get the dust into your eyes, or into any cuts or
scratches .
• If the residue should get into your eyes , flush them with
water. •

Repair, care and disposal of the airbags
Parts of the airbag system are installed at many different places on
your Audi. Ins tal li n g, r em ovin g, s erv ic ing o r re pairi ng a part in an
area of the veh icle can damage a part of an a irbag system and
prev ent th at system from working pr oper ly in a c ollisio n.
There are some important things you have to know to make sure
that the effect ive ness of the system will not be impai red and that
discarded co mpone nts do not cause inju ry or po llute t he env iro n­
ment .
& WARNING
Improper care , servicing and repair procedures can increase the
r isk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly:
• Never cover , obstruct , or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way.
• Never attach any objects such as cup holders or telephone
mountings to the surfaces covering the airbag units.
• For cle aning the horn pad or instrument panel , use only a soft ,
dry cloth or one moi stened with plain water. Solvents or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adjust , or change any parts of the airbag system.
• All work on the steering wheel , instrument panel, front seats or
electrical system (including the installation of audio equipment ,
cellular telephones and CB radios, etc .} must be performed by a
qualified technician who has the training and spec ial equipment
ne cessary .
• For any work on the airbag system , we strongly recommend
that you see your authorized Audi dealer or qualified workshop .
• Never modify the front bumper or parts of the vehicle body.
& WARNING (continued)
• Always make sure that the side airbag can inflate without inter­
ference :
- Never install seat covers or replacement upholstery over the
front seatbacks that have not been specifically approved by
Audi .
- Never use addit ional seat cushions that cover the areas
where the side airbags inflate.
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi ­
ately by an authorized Audi dealer .
• The airbag system can be activated only once . After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information , training
and special equipment necessary.
• The airbag sy stem can be deployed only once . After an airbag
has been deployed , it must be replaced with new replacement
parts designed and approved especially for your Audi model
version. Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .

Braking
General "nformation
What aff ects braking effi cie ncy?
Operating condition s and driving habits
The brakes on today's automob iles a re sti ll sub ject to wea r,
depending large ly o n operati ng co nditions and driving habits~&.
On vehicles which are driven mostly in stop -and -go city traffic or
whic h are driven hard, the brake pa ds shou ld be checked by your
authorized Audi dea ler more often than specified in the
Mainte ­
nance
& Warranty booklet.
On steep slopes, you should use the braking effect of the en gine.
Th is way, you prevent u nneces sary wea r on the brake syste m. If you
must use your brakes, do not ho ld the brakes down continuous ly.
P ump the brakes at interva ls.
Moisture or road salt
U nde r certain co nditi ons, for example, when driving th rough water
or v ery heavy rain, or eve n after washing your vehicle, the braking
effec t can be red uced d ue to mo isture (o r in freezing c onditions ice)
o n the brake pads . A few cautious brake appl ica tions should dry off
the brake pads or remove any ice coat ings.
T he effe ctiveness of the brakes can be reduced when the ve hicle is
driven on a sa lt -covered road and the brakes are not used. Li kewise,
you clean off accu mulated sa lt co atin g fr om bra ke discs a nd pads
with a few cautious applications of the brake~&.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corr osi on to for m on the d iscs if the ca r is no t driven regu lar ly or
only for short trips with litt le use of the brakes .
I f the b ra kes a re not used frequently, or if co rros ion ha s formed on
the d iscs, it is adv isable to clean off the pads a nd discs by braking
firm ly a few times from a moderately high speed~& . .,_
