On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) II! 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 while 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

Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c:>page 218.
On-Board Diagnostics
Fig. 16 Locat ion of Data L ink Con nector (DLC)
On-Board D iagnost ics monitors the compo­
nents of your em iss ion control system . Each
monitored component in your engine system
has been assigned a code . In case of a mal­
function, the component will be identified
and the fault stored as a code in the control
module memory.
T he MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem.
If the light illum inates after a refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed
c:> page 218.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe ­
cial diagnostic equipment (generic scan tool
for OBD).
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the
right of the hood release
r=.> fig . 16 .
Your authorized Audi dea ler or a qualified
serv ice station can interpret the code and per­
form the necessary repair.
A WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause

malfunctions, which can increase the risk
of a coll is ion!
Electronic speed limiter
Instruments and warning/indicator lights 31
Your vehicle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h) . This is less than the
maximum speed of your vehicle. To reduce the
risk of sudden tire failure and loss of control if
the veh icle is ope rated at excessive speeds,
your veh icle also has an elect ronic speed limit­
er. The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating . For more information
c:::> page 251.
If the engine control unit receives faulty vehi­
cle road speed s ignals, the Malfunction Indi­
cator Lamp (MIL)
¢,llij will illuminate . If this
occurs, contact the nearest authorized Audi
dealer for assistance.
S models
Your veh icle's top speed is electronically limit­
ed to 155 mph (250 km/h).
I f the engine control unit receives faulty vehi­
cle roadspeed signals, the Malfunction Indica­
tor Lamp (MIU
¢,llij will illum inate. If this oc­
curs, contact the nea rest authorized Audi
dealer for assistance.
8_ WARNING
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather conditions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires insta lled.

Warm and cold Climate controls
Description
App lies to vehicles: with three -zone cl imate contro l or
four -zone a uto mat ic climate contro l
The climate control system warms, cools and
adds humidity to the air in the vehicle interior .
It is the most effective when the windows and
sunroof* are closed . If the temperature inside
the parked veh icle becomes very warm, open­
i ng the w indow br iefly will speed up the cool­
ing process.
In all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip and form a puddle of wate r under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filt er
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals specified in your Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work .
If you drive your vehicle in an area with high
a ir pollution, the filter may need to be
changed more frequently than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authori zed Audi Service Ad­
visor for adv ice.
K ey coded settings
Three-zone climate control: T he b lower set­
ting and air d istribution are stored automati­
cally and ass igned to the remote control key

emitted into the air.
(D Tips
- Keep the air intake s lo ts ( in front of the
w indshield) free from ice, snow and de­
bris in order to maintain the proper func­
tion of the climate control system.
