On-Board Diagnostic system (OBD)
On-Board Diagnostics
Fig. 9 Location of
Data Link Connector
(DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each controlled component in your eng ine system
has been assigned a code. In case of a malfunction, the component
wi ll be identified and the fault stored as a code in the control module
memory .
The MIL lamp may also illuminate if there is a leak in the on-board
fuel vapor recovery system.
If the Light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed~
page 222.
In order to make an accurate diagnosis, the stored data can only be
displayed using special 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 engine hood release lever~ fig. 9. Your authorized
Audi dealer or a qualified service station can inter­
pret the code and perform the necessary repair.•
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models )
The Malfunction Indicator Lamp (MIL) in the instrument cluster
~ page 11, fig. 5 is part of the On-Board Diagnostic (OBD II) system.
T he warn ing/indicator light illum inates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicates that the MIL is working properly .
If the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed limiter may also be
ma lfunction ing. For more information~
page 20, "E lectronic speed
limiter" .
An improperly closed fuel filler cap may also cause the MIL light to
illuminate~
page 222 . •
Electronic speed limiter
Your vehicle may be factory equ ipped with tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your veh icle . To reduce the risk of sudden tire
fai lure and loss of control if the vehicle is operated at excessive
speeds, your vehicle a lso has an electronic speed limiter . The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information~
page 259, "Speed rating
(letter code)".

• reverse gear is engaged.
& WARNING
Broken glass of automatic dimming mirror can cause electrolyte
fluid leakage . Electrolyte fluid can irritate skin , eyes, and respira­
tory system .
• Repeated or p rolonged expo sur e to electrolyte can cau se irrita­
tion to the resp iratory system, esp ecially among people with
asthma or other r espiratory conditions. Get fre sh air immediately

large am ount s of clean water f or at lea st 15 minute s; medical
attention is re commended .
• If electrolyte contacts skin , flush affected area with clean
water for at l east 15 minutes and then wash aff ected area with
s oap and water; medical attention is rec ommended . Thoroughly
wash affected clothing and shoe s before reu se.
• If swallowed and person i s con sciou s, rinse mouth with water

0 Note
Liquid e lectrolyte leaked from a broken mir ror g lass will damage any
plastic surfaces it comes in contact with. Clean up spi lled electrolyte
immediately with clear wate r and a sponge.
[I) Tips
• Check to make su re t he re are no obje cts preventing light from
reac hing the inside mirror.
• Do not attach any st ick er s to the w indshield in front of the light
sensor, as this would interfere with the a utomatic operation of the
head lights and the a utomat ic dimming of the inside mir ror. •

°F (+28 °().
- Press the [AUTO] but ton .
With this setting, you attain maximum comfort in the least amount

Th e system automatica lly compensates for changes in the outside
tempe ra ture and for the intensity of the sunlight enteri ng the
vehicle. We recommend you use the
Automatic mode ~ page 98 for
year- ro und co mfort.
Please note the following:
T urn on the air conditioner to reduce humidity in the vehicle . This also
preven t the wi ndows from fogging up .
When the outs ide temperature is hig h and the air is very humid,
condensation from t he ev apo ra to r m ay d rip under t he veh icle . T his is
normal and does not indicate a leak.
Controls and equip ­
ment Safety first
Warm and cold
If the outside temp

highe r speed once the engine coolant has warmed up s ufficient ly .
Th e air condi tioner tempo rari ly swi tches off when yo u drive off from
a standstill using full throttle to save engine power.
Th e comp resso r also switches off if the coolant temperature is too
high so that the engine can be adeq uate ly coo led unde r extreme
loads.
Air pollutants filter
Th e a ir po llutants filter (a combined pa rticle filte r and activated cha r­
coa l f il ter) reduces or elim inates outs ide a ir pollution (dus t, or
pollen) from entering the veh icle.
Th e air pollutants fi lter mus t be changed at t he in terv als specified i n
