Convertible top
Convertible top
General information
The comprehensively engin eered design of the
f abric convertib le top a llows it to be operated
qu ickly and simply. When open, the convert i­
b le top is stowed completely in a tonneau pro­
vided spec ifically for this purpose.
I n normal operating conditions, the converti­
b le top is wind -and waterp roof. Under certa in
circumstances, a small quantity o f droplets
might form, but on ly in extremely inclement
weather, e.g . torrentia l or contin uous heavy
rain. This is normal and not a cause for con­
cern.
F ollow the care instructions
Q page 155 to
maintain the convertible top's attractive ap­
pearance and to keep it wind- and waterproof.
Please follow these instructions as well:
- Stow and open the convertib le top only
when it is clean. When the top is folded
away, sharp-edged contaminants can build
up as silt and cause wear spots o n the rear
window, which may damage the convertible
top over time. Of course, ice and snow should also be removed before open ing the
convertible top.
- Under no c ircumstances should you use
sharp-edged or abrasive objects to remove
ice and snow . Use a commerc ial ice scraper
to remove ice from o f the rear window.
- T he convert ible top should be opened only if
it is complete ly d ry. If the convertib le top is
opened and then stored wet, unattractive
indentations may develop . In addition, over
time, mold and mildew stains can develop.
- Do no t leave the convertible top open for
several weeks at a time; instead, open and
close it from time to time so that the fabric
does not disco lor where it folds, and to pre­
vent creases from forming. This is espec ially
important if it happens to be stowed wh ile
still damp on occasion.
- Because the fabric becomes less flexible
when temperatures drops below zero, we
Convertible top 41
recommend not operating the convertible
top below O°C.
A WARNING -
- When operat ing the convertible top,
make sure that any external factors (e.g.
the wind) do not impair its funct ion or
e ndanger other drivers.
- Never drive wh ile the convertib le top is
not properly secured. Otherwise , it may
be pulled open by the wind. This can
cause injur ies and damage to the vehicle
- danger of an accident!
- When opening and closing the converti-
ble top make sure to keep yourself and
o thers clear of a ll movi ng pa rts. Risk of
in jur y!
d) Note
-Always make su re that there is enough
clearance above the veh icle so that the
c onvertib le top is not damaged when
opening and clos ing.
- Do not place any objects in the tonneau
t o avoid damage when open ing the con­
ver tible top.
(D Tips
- Th e convert ible top should be operated
only wi th the ign ition sw itched on.
- When pa rking the ca r with the convert i­
ble top open, bear in mind t hat the vehi­
cle's in terior is not p rotec ted fro m dam­
age due to unexpec ted weather condi­
tions, o r unauthorized access . It is there ­
fore advisab le to close the convertib le
top before leaving the veh icle. If objects
are left inside the vehicle, they should be
locked in the luggage compartment.

Climate controls
Controls
The air conditioning automatically maintains the selected temperature in the vehicle interior
throughout each season .
Fig. 79 Climate contro ls
We recommend the following sett ing :
> Rotate the knob 9 fig. 79 @ to the right to
switch on the air conditioning .
> Set the temperature to 72 °F (22 °().
> Press the !AUTO !~ fig. 79 button .
Using the previously recommended setting is
the quickest way to achieve a comfortable cli ­
mate in the vehicle . This setting should there­
fore only be changed when personal comfort
l eve ls or certain circumstances require it.
The climate controls are a combination of au ­
tomatic heating and ventilation systems and a
coo ling system which dehum idifies and coo ls
the air inside the vehicle.
The climate controls automatically maintain a temperature once it has been set. The tem­
perat ure of the air from the vents, fan speed
(air vol ume) and air distribution are also auto­
matically adjusted . The system also takes into
account strong sunshine so that manua l ad­
justment is not necessary. So in almost all
cases,
automatic mode offers the best condi­
tions for the comfort of the occupants at all
times of the year
9 page 71 .
Please note :
In cooling mode , relative humidity in the inte­
rior is reduced . This prevents the windows
from fogg ing up.
When relative humidity and temperatures outside are high ,
condensation can drip from
the a ir condition ing evaporator and form a
pool of water under the vehicle. This is normal
and not an ind ication 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 ­
tu re, with the exception of the defrost set­
t in g.
When accelerating at wide-open throttle, the air conditioning compressor is temporarily
switched off to maintain full engine power.
In order to ensure engine cooling under ex­
treme engine loads, the compressor is switch­
ed off if coolant temperatures climb too high.
Functions are set by turning the rotary knob
or switched on and off by tapp ing the buttons.

Pollutant filt er
The pollutant filter (particle filter) ensures
that contaminants in the outside air (such as
dust or po llen) are greatly reduced or stop­
ped. The air is also filtered in recirculation
mode.
The pollutant filter element must be changed
according to the intervals specified in the
maintenance schedule so that the air condi­
tioning system's performance is not adversely
affected .
If the fi lter's effectiveness is weakened by
driving the vehicle in areas with heavily pollut­
ed outside air, the filter element should also
be changed in between the listed services.
A WARNING
For safety reasons, it is important that all
w indows are free of ice, snow, and conden­
sa tion. Only then is good visib ility ensured.
Please fam iliarize yourse lf w ith the correct
operation of the air conditioning and how
to de humidify/defrost the windows .
(D Note
-If yo u suspect that the clima te controls
have been damaged, switch the system
Warm and c old 69
off to avoid damaging it, and have it in ­
spected by an authorized Audi dealer .
- Audi climate control system repairs re ­
quire special expertise and the proper
tools . You should contact an authorized
Audi dealer in the event of malfunctions.
(D Tips
- To avoid adversely affecting heating and
cooling performance and to prevent con­
densation on the windows, the air intake
in front of the windshield must be free of
ice, snow, and leaves.
- The air coming from the vents and circu­
lat ing through the entire interior is ex­
tracted through the out let slots in the
side pane ls in t he luggage compartment.
Make sure that the outlet slots are not
covered by clothing, etc.
- Climate control works most effectively if
the windows are closed. Howeve r, if the
inter io r of a par ked vehicle is ext reme ly
hot from the sun's rays, briefly open ing
t he windows can speed up the cooling
process .

& WARNING
Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating function. To reduce
the risk of injury, these individuals should
not use seat heat ing .
To avo id damage to the heating e lements
in the seats, do not kneel on the seats or
place heavy loads on a small area of the
seat .
Using the climate controls economically
Economical use of the climate controls helps
to save fuel .
When climate control is working in coo ling
mode, engine performance is reduced and
fuel consumption is affected . To keep the time the air cond
itioning is on as short as possible,
you should do the following:
.,. If you would like to save fuel, switch the air
conditioning off .
.,. If you open the windows while driving,
switch the air conditioning off .
.,. If the veh icle is extreme ly hot due to the
heat of the sun, br iefly open doors and w in­
dows .
@ For the sake of the environment
When yo u save fuel, you reduce emissions
from the vehicle.

_& WARNING
-Always adapt your driving to the traffic
flow.
- Only use Launch Control when road and
traffic conditions allow it and other driv­
ers will not be endangered or annoyed by
your driving and the acceleration of the
vehicle .
- Make sure that ESC remains enabled .
With the ESC disabled, the veh icle could
brake away, particularly on a slick and
slippery road -risk of skidding!
- Once acce lerat ion is finished, switch ASR
on again by briefly pushing the ESC but­
ton.
@ Tips
- The transm ission temperature may in­
crease significantly after using the
Launch Control Program. If that hap­
pens, the program may not be available
for a few minutes. I t will be availab le
again after a coo l-down period.
- When accelerating using the Launch
Control program, all vehicle parts are
subject to heavy loads . This can result in
increased wear.

What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle, the driver as well as the
driver's ability to concentrate on the road
without being distracted.
The driver is responsible for the safety of the
veh icle and a ll of its occupants . If your ability
to drive is impaired, safety risks for everybody
in the vehicle increase and you also become a
hazard to everyone else on the road ¢
,&..
Therefore:
.,. Do not let yourself be distracted by passen­
gers or by us ing a cellular telephone.
.. NEVER drive when your driv ing ability is im ­
paired (by medicat ions, alcohol, drugs, etc.) .
.. Observe all traffic laws, ru les of the road
and speed limits and plain common sense.
.. ALWAYS adjust your speed to road, traffic
and weather conditions.
.. Take frequent breaks on long trips. Do not
drive for more than two hours at a stretch .
.. Do NOT drive when you are tired, under
pressure or when you are stressed.
A WARNING
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used.

For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the driver's seat to the
f o ll ow ing pos ition:
.,. Adjust the driver's seat so that you can easi­
ly push the pedals all the way to the floo r
while keeping your knee(s) slightly bent
q&_ ,
.. Adjust the angle of the seatback so that it is
in an upright position so that your back
comes in full contact with it when you drive.
.. Adjust the steering wheel so that there is a
distance of at least 10 inches (25 cm) be­
tween the steering wheel and your breast
bone¢
fig. 101. If not possible, see your au­
thorized Audi dealership about adaptive
equ ipment .
.. Adjust the steering wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face .
.. Grasp the top of the steering whee l with
your elbow(s) slightly bent .
.. Adjust the head restraint so the upper edge
is as even as possible with the top of your
head . If that is not poss ible, try to adjust
the head restraint so that it is as close to
this pos ition as possib le .
.. Fasten and wear safety belts correctly

Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be t urned off ("sup­
pressed") if a child up to about one year of
age restrained in one of the rear -facing or for­
ward -facing infant restra ints listed in Federal
Motor Vehicle Safety Standard 208 with wh ich
the Advanced Airbag System in your vehicle
was certified has been installed on the front passenger seat. Fo r a listing of the child re­
straints that were used to certify compliance
with the US Safety Standard
¢ page 132.
The PAS SENG ER AIR BAG OFF light in the in­
strument panel tells you when the front Ad­
vanced A irbag on the passenger side has been
turned off by the e lectronic control u nit.
Each t ime you turn on the ignition, the
PAS ­
SENGER AIR BAG OFF
l ight w ill come on for a
few seconds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small child or child
restraint on the front passenger seat,
- wi ll go off if the front passenger seat is oc­
cupied by an adult as registered by the
weight-sensing mat
¢ page 119, Monitor­
ing the Advanced Airbag System.
The PASSENGER AIR BAG OFF light comes on
when the control un it detects a total weight
on the front passenger seat that requires the
front airbag to be turned off .
If the total weight on the front passenger
seat is more than that of a typical 1 year-old
chi ld but less than the weight of a small
ad ult, the front airbag on the passenge r side
can dep loy (the
PASSENGER AIR BAG OFF
light does not come o n). If the PASSENGER
AIR BAG OFF
l ight does not come on, the
front airbag on the passenger side has not
been turned off by the electronic control unit
and can dep loy if the control unit senses an
impact that meets the conditions stored in its
memory.
For e xample , the airbag may deploy if :
Airbag system 11 1
- a small child that is heav ie r th an a typical 1
year -old chi ld is o n the front passenger seat
(regard less o f whether the child is in one o f
the child safety seats listed ¢
page 132), or
- a child who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instr ument pane l and stays on.
T he front airbag on the passenge r side may
not deploy (t he PASSENGER AIR BAG OFF
light does not illuminate a nd stay lit) even if a
small ad ult or teenager, or a passenger who is
not sitting upright with their back against a
non-recl ined backrest w ith their feet on the
vehicle floor in front of the seat is on the front
passenger seat ¢
page 93, Proper seating po ­
sition for the driver.
If the front passenger airbag dep loys, the
Federa l Standard requ ires the airbag to meet
the "low risk" dep loyment criteria to reduce
the risk of injury th rough interact ion w ith the
airbag. "Low risk" deployment occurs in those
crashes that ta ke place at lower dece le rat io ns
as de fined in the e lectronic co ntrol unit
¢ page 1 20, PASSENG ER AIR BAG O FF light.
Always remember, a c hild safety seat or infant
ca rr ier installed on the front seat may be
stru ck and kno cked out of po sit io n by the rap­
idly in flat ing passenger 's airbag in a fronta l
collision. The ai rbag co uld great ly red uce the
effectiveness of the chi ld restraint and even
seriously in jure the child during inflation.
A WARNING
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be ser ious ly injured and can be killed if
the front airbag inflates - even with an Ad­
van ced A irbag System.
- The inflating airbag will h it the ch ild

Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants .
Fig. 112 Location of dri ver airbag: in steering whee l
Fig. 113 Location of front passe nger's ai rb ag : in the in­
strument panel
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured . The safety belts
for the front seats have "pretensioners" that
help to take slack out of the belt system. The
pretensioners are also activated by the elec­
tronic control unit for the airbag system.
The front safety belts also have load limiters
to help reduce the forces applied to the body
in a crash .
The airbag for the driver is in the steering
wheel hub¢
fig. 112 and the airbag for the
front passenger is in the instrument panel
¢fig. 113. The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air­
bags in your vehicle. We urge you to read the
Airbag system 113
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature .
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in ­
fants and small children.
A WARNING ,.;;
Never rely on airbags alone for protection .
- Even when they deploy, airbags provide
only supplementa l protection.
- Airbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts
and make sure that everybody in your ve­
hicle is properly restrained.
A WARNING
A person on the front passenger seat, es­
pecially infants and small children, will re­
ceive serious injuries and can even be kil­
led by being too close to the airbag when
it inflates .
- Although the Advanced Airbag System in
your vehicle is designed to turn off the
front passenger airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
that deployment under these special
conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle .
- The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U.S. Federal Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other condit ions for airbag de­
ployment are met.
- For its own safety, a child should always
ride properly restrained for its age and
size.

-
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
Ill>

114 Airbag sys te m
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was manufactured .
The front Advanced Airbag Sys tem supp le­
ments the safety belts to provide additional
protection for the driver's and front passeng­
er 's heads and upper bodies in fronta l crashes.
The airbags inflate only in fronta l impacts
when the vehicle dece lerat ion is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of the over­ all occupant restraint system in your veh icle.
A lways remember that the airbag system ca n
only help to protect you, if you are s itting up­
right, wearing yo ur safety belt and wea ring it
p roperly. This is why you and you r passenge rs
must always be properly restr ained , not just
beca use the law requires you to be.
The Advanced Airbag System i n your veh icle
has been cer tified to meet the " low r is k " re­
qu iremen ts for
3 an d 6 year-o ld childre n on
the passenger side and very small adu lts on
the driver side. The low risk deploymen t crite ­
ria are intended to he lp red uce the risk of in­
jury through interaction with the front airbag that can occur, for example, by be ing too
close to the steer ing whee l and instrument
panel when the airbag i nflates .
In addition, the system has been certif ied to
comp ly w ith the "suppression" requ irements
of the Safety Standard, to tur n off the front
a irbag for infants
12 months old and younger
who a re restra ined on the front passenger
seat in c hild restra ints that a re listed in the
St anda rd ¢
page 132, Child restraints and
Advanced Airbags.
"Suppression" requires the front airbag on the passenger side to be turned off if :
- a ch ild up to about one year of age is re­
stra ined on the front passenger seat in one
of the rear-facing or forwa rd-fac ing infa nt
rest raints listed in Federa l Motor Veh icle
Safety Standard 208 wit h whi ch the Ad­
vanced Airbag System in your vehicle w as
certified . For a list ing of the child rest rain ts t
ha t were used to certify your vehicle 's com ­
pliance with the US Safety Standa rd
¢ page 132,
-weight less than a thres ho ld level stored in
the control unit is detected on the front pas­
senger seat.
When a person is dete cted on the front pas ­
senger seat, weighing more than the tota l
weight of a chi ld that is about
1 year old re­
stra ined in one of the rear-facing or forward­
facing infant restraints ( listed in Federal Mo­
tor Vehicle Safety Standard 208 w it h which
the Advanced Airbag System in your vehicle
was ce rtified), the front airbag on the passen­
ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
whe n the electro nic con trol unit detects a to­
ta l we ight on the front passenger seat that re­
quires t he front airbag to be tu rned off. If t he
PASSENGER AIR BAG OFF ligh t does no t
come o n, the fron t airbag on the passenger
s ide has not been turne d off by the cont ro l
u nit and can dep loy if the control unit senses
an impact that meets the conditions stored in
its memory.
If the total weight on the front passenge r
seat is more than that of a typica l
1 year-old,
but less than the we ight of a small ad ult, the
front a irbag on the passenger side may dep loy
(the
PASSENGER AIR BAG OFF light does not
come on).
For example , the airbag may deploy if:
- a small ch ild that is heav ier t han a typic al 1
yea r-old ch ild is on the front passenger seat
(regard less of whethe r the child is in one of
the child safety seats listed
¢ page 132),
-a child who has outgrown ch ild restraints is
on the front passenge r seat .
If the fron t passenger a irbag is turned off, the
PASSENGER AIR BAG OFF ligh t in the cen ter
of the ins trument panel will come on and stay
o n.
T he front airbag on the passenge r sid e may
not dep loy (the PASSENGER AIR BAG OFF
li ght does not illuminate a nd stay lit) i f:
