Defective light bulb warning
The defective light bulb warning tells you when a vehicle
light bulb has become defective.
If a defective bulb has been detected by the system or a light bulb
burns out, the symbol with a message appears in the display to
tell you which bulb is burnt out and where it is located. For example:
REAR LEFT TURN SIGNAL
After 5 seconds, the message disappears. If you want to recall the
message into the display, press the CHECK button.
There are three reasons why the defective bulb message would appear in the display:
• the light bulb has burnt out=> page 277.
• the fuse is "blown" => page 273, "Replacing a fuse".
• the wire connection to the light bulb is defective.
Have the bulb replaced or the connection repaired by your autho ­
rized Audi Service department.
& WARNING
• Light bulbs are pressurized and could explode while they are
being changed causing serious personal injury.
• Work with due care when handling the high-voltage section of
gas discharge (xenon) lamps*. Failing to do so could result in death
or serious injury! •
Brake light defective K: U (USA

In case of a malfunction or component failure, the acoustic warning
will sound and the symbol&;

The following electrical components should be checked, repaired or
replaced, as necessary :
• Brake light bulbs
• All wiring connections
• Brake light switch
Contact your authorized Audi dealer for assistance if necessary.
[ i] Tips
The brake light switch is only inspected as part of the functional
check after the engine is started. •

System malfunction
If the t warning light in the instrument cluster flashes for approxi ­
mately one minute and then remains continuously illuminated and
additionally the
r fin'-=> fig. 30 symbo l appears in the display, the
tire pressure monitoring system is not available. This can have
various causes .
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a whee l sensor were
installed.
• A wheel sensor or other component may have failed .
• During initia lization the system has detected more than 4 wheels
on the vehicle, for example whi le driving next to another car with a
tire pressure monitoring system.

• A wheel change was made but the button => page 44, fig. 29 was
not pressed .
• Audi replacement parts were not used.
• If snow chains are being used, system function can be compro­
mised due to the shielding properties of the chains.
• The tire pressure monitoring system may not be available
because of a radio malfunction.
• Transmitters with the same frequency, such as radio head ­
phones in the vehic le or radio equipment, can cause a temporary
disruption of the system through excessive e lectromagnetic fields.
• Eliminate the interference if possible/if you can and then
proceed as follows: Turn off the engine for 20 minutes . Then drive
another 10 min. If the warning light comes on again, you should
contact your authorized Audi dealer immediately to have the
problem corrected.
• Do not use commercially available tire sealants. Otherwise, the
e lectrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system will have to be replaced by a qualified workshop. •

Folding top
Folding top
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
~

-Press and hold the switch down throughout the closing
procedure.
The folding top is completely open or closed when the indicator
light <:-in the instrument cluster goes out. The door windows are
automatically lowered about 20 mm while the top is opening .
& WARNING
Never drive the vehicle with the top not properly latched! Other­
wise there is a risk that the top will be opened by the wind. This
can result in injuries and damage to the vehicle.
[ i] Tips
• Opening and closing the automatic convertible top is possible
below posted speed limits in city driving . At speeds above 4 mph (6
km/h), you can use the "convenience opening" function. The folding
top is completely opened by briefly pulling on the switch.
• The indicator light for the folding top goes out as soon as it is
correctly latched .
• In order not to discharge the battery unnecessarily, the top
should not be lowered or raised several times in succession with the
engine not running.
• I f the indicator light for the folding top flashes when the switch
is actuated, there is a malfunction. •
