On-Board Diagnostics
Fig. 15 Lo cat ion of D ata Link Connec tor (D LC)
On-Board Diagnostics monitors the compo­
nents of your emission con trol system. Each
monitored component in your engine system
has been assigned a code . In case of a mal­
function, the component will be ident ified
and the fau lt stored as a code in the control
module memory .
The MIL light may also illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem.
If the lig ht illuminates after a refuelling ,
stop the veh icle and ma ke sure the fuel filler
cap is proper ly closed
<> page 212.
I n o rder to make an accurate d iagnosis, the
stored data can only be displayed using spe­
cia l diagnostic eq uipment (gener ic s can tool
for OBD).
I n o rder to connect the special diagnostic
equipment, push the p lug i nto the Data Link
Connector (DLC). The DLC is located to the
right of the hood release¢

Your author ized A udi dealer or a qualified
service station can interp ret the code and pe r­
form the necessary repa ir .
A WARNING
Do not use the diagnostic con nector for
personal use. Incorrect usage can ca use
ma lf u nctions, which can increase the risk
of a coll ision!

Electronic speed limiter*
Applies to vehicles: with electronic speed limiter
Your vehicle may be factory eq uipped w ith
t ir es that are rated fo r a max imum speed of
130 mph (210 km/h) . This is less than the
maximum speed of your vehicle. To reduce the
risk of sudden tire fa ilure and loss of contro l if
the vehicle is operated at excessive speeds,
your vehicle a lso has an electronic speed limit­
er . The elec tronic speed limi ter prevents your
vehicle from going faster than the tire speed rating . For more information ¢
page 248.
If the engine control unit receives faulty veh i­
cle road speed signa ls, the Malfunction Ind i­
cator Lamp (M IL)
¢..fi will illuminate . If this
occurs, contact the nea rest authorized A udi
dealer for assistance .
A WARNING
Always observe the posted speed lim its
a nd adjust your speed to suit prevai ling
road, traffic and weather cond itions. Never

Power top
Automatic power top
General information
The power top opens and closes automatical­ ly . When open, the power top is stored com­
pletely in the power top compartment. The
power top can be opened or closed at speeds
up to 30 mph (SO km/h).
Under normal conditions, the power top is
wind and waterproof. In rare cases, small
droplets of water may form under extreme
weather conditions such as torrential or pro­ longed rain. That is normal and no cause for
concern.
Follow the care instructions to keep the power
top free of leaks and to maintain its appear­
ance
c::> page 204, Core and cleaning. Also ob­
serve the following:
- Op en and stow the power top only when it is
clean and dry . Sharp-edged dirt particles can
cause damage to the rear window and the
power top. Stowing the power top when it is
damp can create imprints in it, and if it is
left that way for long periods of time, mil­
dew and other damage can form.
- Do not leave the power top open for several
weeks or the creases in it may become dis­
colored.
- Remove ice and snow before opening the
power top. Do not use any sharp edged ob­
jects to remove ice and snow or the power
top could be scratched or damaged. The rear
window may be cleared with a standard ice
scraper.
- Do not open the power top when the tem­
perature is below 32 °F (0 °C). The fabric in
the power top loses elasticity in sub-ze ro
temperatures.
_& WARNING
- When positioning the power top, avoid
contact with the supports or other mov­
ing parts. Make sure all of the windows
.
Power top 41
are lowered. Otherwise you could pinch
your hands.
- Never drive when the power top is not
locked correctly. The wind from driving
could cause the power top to open. This
can result in injuries and damage to the
vehicle.
Opening and closing the power top
Fig. 27 Center console: power top switch
Requirement: The power top storage com­
partment must be lowered
c::> page 43 and
the luggage compartment lid must be closed.
.. Switch the ignition on.
.. To open or close the power top, pull or press
the button @during the entire process.
T he status of the power top is shown in the in­
strument cluster display when operating the
power top switch.
You can close the power top when the wind
deflector is installed
~ page 44.
A message will appear in the instrument clus­
ter if the power top cannot be opened or
closed
c::> page 43.
A WARNING
- When operating the power top, make
sure the function is not affected by wind
or other factors and that it does not in­
terfere with other drivers.
- Never drive when the power top is not
locked correctly. The wind from driving
could cause the power top to open. This
can result in injuries and damage to the
vehicle.

parking brake
Operating
The electromechanical parking brake replaces
the hand brake.
Fig. 82 Ce nter conso le: Park ing brake
~ Pull the switch@~ fig. 82 to set the park­
ing brake . The . (USA models)/ . (Cana­
da models) indicator lights in the button
and in the instrument cluster display turn
on .
~ To release the parking brake, press the brake
or acce le rator pedal while the ignit ion is
switched on and press the button @at the
same time. The. (USA models)
I. (Can­
ada models) indicator lights in the button
and in the display turn off .
Your veh icle is eq uipped with an electrome­
chanical parking brake. The parking brake is
designed to prevent the vehicle from rolling unintentionally and replaces the hand brake.
I n addition to the normal functions of a tradi­
tional hand brake, the electromechanical parking brake provides various convenience
and safety functions.
When starting from a stop
- T he integral hill start assist helps you when
dr iving by automatically releasing the park­
ing brake ~
page 83, Starting from a
stop .
-When starting on inclines, the hill start as­
sist prevents the vehicle from unintentional­
l y rolling back. The braking force of the
parking brake is not released until sufficient driving force has been built up at the
wheels.
Emergency brake function
An emergency braking functions ensu res that
the vehicle can be slowed down even if the
normal brakes fail~ page 84, Emergency
braking function.
_.&. WARNING
- Do not press the accelerator pedal inad­
vertently when the vehicle is stationary
and the engine is running and a gear is
selected. Otherwise the vehicle will start
to move immediately and could result in
a crash .
- If the power supply fails, the released
parking brake can no longer engage . In
this case, park the vehicle on leve l
g round and secure it by placing these­
lecto r lever in the P position. See an au­
thorized Audi dealer or authorized Audi
Service Facility for assistance.
(D Note
If the. or. (USA models) I. (Cana­
da models) indicator light in the instru­
ment cluster blinks, there is a malfunction
i n the brake system. Refer to the detai led
description of the indicator lights
~page 18.
- If the . (USA models) I. (Cana-
da models) or
Ill indicator light turns
on, there is a malfunction in the parking
brake
c> page 19.
(D Tips
- If the electromechanica l parking brake is
set while the ignition is switched off, the
¢@'A indicator light in the button and in
the instrument cluster dis-
play . (USA models) /. (Cana-
da models) will turn off after a certain
amount of time.
- If driver's door is opened while the igni­
tion is switched on, the park ing brake
sets automatically. This prevents unin­
tended rolling of the vehicle.
