-L Engine cooling system
A malfunction in the engine cooling system
must be repaired as soon as possible.
When the. symbol in the display flashes,
then either the eng ine coolant
temperature is
too high, or the coolant
level is too low . In ad ­
d ition to the symbol, the following message
a lso appears in the display:
S witc h off engin e and ch eck c ool ant l evel
~ Pull off the road and stop the vehicle.
~ Turnoff the engine.
~ Check coolant level ¢ page 172.
~ Add coolant if necessary¢ page 172.
~ Conti nue driving only after the eng ine cool ­
ant warn ing/ indicator l ight goes out .
~ Contact you r authorized Audi dea le r fo r as-
s istance if necessary.
If the engine coolant level is correct, then the radiator fan may be the cause of the malf unc­
tion .
If the generator warning/ind icator light
should also illuminate¢
page 16, then the
fan belt may be damaged .

(D Note
Do not continue driving if the. symbo l
illuminates . There is a malfunct ion in the engine cooling system
-you could damage
your engine.
~ Electro-mechanical power assist
If the indicator light i lluminates while you are
driv ing, there is a malfunction in the electro­
mechan ica l steer ing. If the indicator light is
showing £~ ). there may be a reduction in pow ­
er steeri ng assist . If the indicator light is
showing ., there may be a total loss of pow­
er steeri ng assist. The steer ing must be in ­
spected immed iately by a qualified wo rkshop
Q & . With the engine not running (e.g. when
the car is being towed), there is a lso no power

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) Ill in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes o ut after
the engine starts and the idle has stabilized.
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
is started, or illuminates whi le you are driv­
ing, a ma lfunction may exist in the engine sys­
tem. If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
information ¢

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 154 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.

Warm and cold Climate controls
Controls
W arm and cold 6 7
The air conditioning automatically maintains the selected temperature in the vehicle interior
throughout each season .
Fig. 78 Climate contro ls
We recommend the following sett ing :
• Rotate the knob
c::> fig. 78 @ to the right to
switch on the air conditioning .
• Set the temperature to 72 °F (22 °() .
• Press the
!AUTO I c::> fig . 78 button .
Using the previously recommended setting is
the quickest way to achieve a comfortable cli ­
mate in the vehicle . Th is setting should there­
fore only be changed when persona l comfort
l eve ls o r certain circumstances requ ire 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 tem­pe rat ure of the air from the v ents, fan speed
(air vo lume) and ai r distribu tion are also auto ­
mat ica lly adjusted . The system also takes into
account strong sunshine so that manua l ad ­
justment is not necessary . So in almost all
cases,
a utomatic mode offers the best cond i­
tions for the comfort of the occupants at all
times of the year
c::> page 70 .
Plea se note:
In cooling mode, relative humidity in the inte­
rior is reduced . This prevents the w indows
from fogg ing up .
When relative hum idity and temperatures
outside are high,
condensation can drip from
the a ir cond ition ing evaporator and form a
poo l of water under the veh icle. 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 ing.
When accelerating at wide-open throttle, the
air condit ioning compressor is temporar ily
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 cl imb too high .
Funct ions are set by turn ing the rotary knob
or switched o n and off by tapp ing the buttons.

Pollutant filt er
The pollutant filter (particle filter) ensures
that contaminants in the outside air (such as
d ust or pollen) are greatly reduced or stop­
ped. The air is also filtered in recircu lation
mode.
The po llutant 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 filter'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
sation. Only then is good visib ility ensured.
Please fam iliari ze yourse lf with the co rrec t
operation of the air conditioning and how
to de humidify/defrost the windows .
([) Note
-If you suspect that the clima te controls
have been damaged, swi tch the system off to avoid damaging it, and have it in­
spected by an authorized Audi dea
ler .
- 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 a ir 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 the luggage compartment .
Make sure that the outlet slots are not
covered by clothing, etc.
- Climate contro l works most effectively if
the windows are closed. However, if the
inter io r of a par ked veh icle is ext reme ly
hot from the sun's rays, briefly opening
the windows can speed up the cooling process .

86 Transmis sion
& 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 vehicle 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.
(j) Tips
- The transmission 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.

- When accelerating using the Launch
Control program, all vehicle parts are
subject to heavy loads . This can result in
increased wear.
Back-up program
In the event of a system malfunction, there is
a back-up program.
In the event of system malfunction, the auto­
matic transmission switches to the fail-safe
mode. Al l of the selector lever position dis­
plays for the automatic transmission are high­
lighted with a light background in the instru­
ment cluster display . In some cases you can­
not use reverse gear any more.
If the transmission switches to fail-safe mode, you should take the vehicle to an au­
thorized Audi dealership as soon as possible
to have the condition corrected .

92 Driving Safel y
• Fasten your safety be lt and wear it properly .
Also instruct your passengers to fasten their
safety belts proper ly ¢
page 100.
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 rood
without being distracted.
The driver is responsible for the safety of the
vehicle and all 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 using a cellular telephone.
• NEVER drive when your dr iving ability is im­
paired (by medicat ions, alcohol, drugs, etc.) .
• Observe all traffic laws, rules 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 ,.
Impai red driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used.
Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving.
Fig. 99 The correct distance between driver and steer­
ing whee l
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 llow ing position:
• 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. 99 . If not possible, see your au­
thorized Audi dealersh ip 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 he ad restraint so the upper edge
is as even as possible with the top of your
head . If that is not possible, 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
